We are products of complexity,
but our evolution has focused our
understanding on the situation of hunter gatherers on the
African savanna.
As humanity has become more powerful we can significantly impact
the systems we depend on. But we struggle to comprehend
them. So this web frame
explores significant real world complex
adaptive systems (CAS):
- Assumptions of randomness & equilibrium allowed the
wealthy & powerful to expand the size and leverage of
stock markets, by placing at risk the insurance and
retirement savings of the working class. The
assumptions are wrong but remain entrenched.
- The US nation was built from two
divergent political views
of: Jefferson and Hamilton. It also reflects the development of competing
ancient ideas of Epicurus and Cyril. But the
collapse of Bretton Woods forced Wall Street into a position
of power, while the middle and working class were abandoned
by the elites. Housing financed with cash from oil and
derivative transactions helped hide the shift.
- Most US health care is still
operating the way cars built in the 1940s did.
Geisinger is an example of better solution. But
transforming the whole network is a challenge. And
public health investment has proved far more
beneficial.
- Helping our children learn to be
effective adults is part of our humanity, but we have
created a robust but deeply flawed education system.
Better alternatives have emerged.
- Spoken language, reading and writing emerged allowing our
good ideas to
become a second genetic material.
- The emergence
of the global economy in the 1600s and its subsequent
development;
It explains how the examples relate to each other, why we all
have trouble effectively comprehending these systems and
explains how our inexperience with CAS can lead to catastrophe. It
outlines the items we see as key to the system and why.
Example systems frame |
Dietrich Dorner argues complex adaptive systems (CAS) are hard to understand and
manage. He provides examples of how this feature of these
systems can have disastrous consequences for their human
managers. Dorner suggests this is due to CAS properties
psychological impact on our otherwise successful mental
strategic toolkit. To prepare to more effectively manage
CAS, Dorner recommends use of:
- Effective iterative planning and
- Practice with complex scenario simulations; tools which he
reviews.
Complexity catastrophes |
E. O. Wilson reviews the effect of man on the natural world to
date and explains how the two systems can coexist most
effectively.
Adaptive ecology |
Barton Gellman details the strategies used by Vice President
Cheney to align the global system with his economics, defense, and
energy goals.
US vds alignment |
Kevin Kruse argues that from 1930 onwards the corporate elite
and the Republican party have developed and relentlessly
executed strategies to undermine Franklin Roosevelt and the New Deal. Their
successful strategy used the credibility of conservative
religious leaders to:
- Demonstrate religious issues
with the New Deal.
- Integrate the corporate
elite and evangelicals.
- Use the power of corporate
advertising and Hollywood to reeducate the American
people to view the US as historically religious and
the New Deal and liberalism as anti-religious
socialism.
- Focus the message through evangelicals including Vereide and Graham.
- Centralize the strategy through President Eisenhower.
- Add religious elements to
mainstream American symbols: money, pledge;
- Push for prayer in
public school
- Push Congress to promote prayer
- Make elections more
about religious positions.
Following our summary of his arguments RSS frames them from the
perspective of complex adaptive system (CAS) theory.
Strategy is the art of the possible. But it also depends
on persistence.
Inventing Christian America |
Charles Ferguson argues that the US power structure has become
highly corrupt.
Ferguson identifies key events which contributed to the
transformation:
- Junk bonds,
- Derivative
deregulation,
- CMOs,
ABS and analyst fraud,
- Financial network deregulation,
- Financial network consolidation,
- Short term incentives
Subsequently the George W. Bush administration used the
situation to build
a global bubble, which Wall Street
leveraged. The bursting of the
bubble: managed
by the Bush Administration and Bernanke Federal Reserve;
was advantageous to some.
Ferguson concludes that the restructured and deregulated
financial services industry is damaging to
the American economy. And it is supported by powerful, incentive aligned academics.
He sees the result being a rigged system.
Ferguson offers his proposals
for change and offers hope that a charismatic young FDR will appear.
Following our summary of his arguments, RSS comments on them framed by
complex adaptive system (CAS)
theory. Once the constraints are removed from CAS
amplifiers, it becomes advantageous to leverage the increased flows. And it is often
relatively damaging not to participate. Corruption and parasitism can become
entrenched.
Financial WMD |
Matt Taibbi describes the phenotypic
alignment of the American justice system. The result
he explains relentlessly grinds the poor and undocumented into
resources to be constrained, consumed and ejected. Even as
it supports and aligns the financial infrastructure into a
potent weapon capable of targeting any company or nation to
extract profits and leave the victim deflated.
Taibbi uses five scenarios to provide a broad picture of the:
activities, crimes, policing, prosecutions, court processes,
prisons and deportation network. The scenarios are:
Undocumented people's neighborhoods, Poor neighborhoods, Welfare
recipients, Credit card debtors and Financial institutions.
Following our summary of his arguments, RSS comments on them framed by
complex adaptive system (CAS) theory. The alignment of the
justice system reflects a set of long term strategies and
responses to a powerful global arms race that the US leadership intends to
win.
Aligned justice |
Jonathan Powell describes how the government of, the former UK Prime Minister, Tony Blair,
actually operated. Powell was Blair's only chief of
staff.
Mechanics of power |
H. A. Hayek compares and contrasts collectivism and
libertarianism.
Libertarianism |
John Doerr argues that company leaders and their
organizations, hugely benefit from Andy Grove's OKRs.
He promotes strategies
that help OKR success: Focus,
Align, Track, Stretch; replaces yearly performance
reviews, and provides illustrative success
stories.
Doerr stresses Dov Seidman's
view that employees are adaptive and will
respond to what they see being measured. He asserts culturally supported OKRs/CFR processes will be transformative.
Following our summary of his arguments, RSS comments on them
framed by complex adaptive system (CAS) theory. Doerr's architecture
is tailored for the startups KPCB
invests in. It is a subset of the general case of schematic plans, genetic operators and Shewhart cycles that drive all
CAS. Doerr's approach limits support of learning and deemphasizes the
association to planning.
Startup PDCA |
David Bodanis illustrates how disruptive effects can take
hold. While the French revolution had many driving forces
including famine and
oppression the emergence of a new philosophical vision ensured
that thoughtful leaders
were constrained and conflicted in their responses to the
crisis.
Voltaire's disruptive network |
An epistatic meme suppressed for a thousand years reemerges
during the enlightenment.
It was a poem
encapsulating the ideas of Epicurus rediscovered by a
humanist book hunter.
Greenblatt describes the process of suppression and
reemergence. He argues that the rediscovery was the
foundation of the modern world.
Complex adaptive system (CAS) models of the memetic mechanisms
are discussed.
Constraining happiness |
Isaacson uses the historic development of the global cloud of
web services to explore Ada
Lovelace's ideas about thinking
machines and poetic
science. He highlights the value of computer
augmented human creativity and the need for liberal arts to
fulfill the process.
Complex adaptive system (CAS) models of agent networks and
collaboration are discussed.
Arts technology & intelligence |
Haikonen juxtaposes the philosophy and psychology of
consciousness with engineering practice to refine the debate on
the hard problem of consciousness. During the journey he
describes the architecture of a robot that highlights the
potential and challenges of associative neural
networks.
Complex adaptive system (CAS) theory is then used to illustrate the
additional requirements and constraints of self-assembling
evolved conscious animals. It will be seen that
Haikonen's neural
architecture, Smiley's Copycat
architecture and molecular biology's intracellular
architecture leverage the same associative properties.
Associatively integrated robots |
Good ideas are successful because they build upon prior
developments that have been successfully implemented.
Johnson demonstrates that they are phenotypic expressions of
memetic plans subject to the laws of complex adaptive systems (CAS).
Developing ideas |
A government sanctioned monopoly
supported the construction of a superorganism
American Telephone and
Telegraph
(AT&T). Within this Bell Labs was at the center of
three networks:
- The evolving global scientific
network.
- The Bell telephone network. And
- The military
industrial network deploying 'fire and missile
control' systems.
Bell Labs strategically leveraged each network to create an innovation
engine.
They monitored the opportunities to leverage the developing
ideas, reorganizing to replace incumbent
opposition and enable the creation and growth of new
ideas.
Once the monopoly was
dismantled, AT&T disrupted.
Complex adaptive system (CAS) models of the innovation mechanisms are
discussed.
Strategic innovation |
Roger Cohen's New York Times opinion about the implications of
BREXIT is summarized. His ideas are then framed by complex
adaptive system (CAS) theory and
reviewed.
BREXIT |
Scott Galloway argues that Apple, Amazon, Facebook and Google
are monopolists that
trade workers for technology. Monopolies that he argues
should be broken up to ensure the return of a middle
class.
Following our summary of his arguments, RSS comments on these arguments
assuming they relate to a complex adaptive system (CAS).
While Scott's issue is highly significant his analysis conflicts
with relevant CAS history and theory.
Monopoly job killers |
The IPO of Netscape is
defined as the key emergent event of
the New Economy by Michael Mandel. Following the summary
of Mandel's key points the complex adaptive system (CAS) aspects are highlighted.
New economy |
Ed Conway argues that Bretton Woods produced a unique set of
rules and infrastructure for supporting the global economy. It was
enabled by the experience of Keynes
and White during and after the First World War, their dislike of the Gold Standard,
the necessity of improving
the situation between the wars and the opportunity created
by the catastrophe of the Second
World War.
He describes how it was planned
and developed. How it
emerged from the summit.
And he shows how the opportunity inevitably allowed the US to replace the UK at the center of the global economy.
Like all plans there are
mistakes and Conway takes us through them and how the US recovered the situation as
best it could.
And then Conway describes the period after
Bretton Woods collapsed. He explains what followed
and also compares the relative performance of the various
periods before during and after Bretton Woods.
Following our summary of his arguments RSS comments from the
perspective of Complex Adaptive System (CAS)
theory. Conway's book illustrates the rule making and
infrastructure that together build an evolved amplifier.
He shows the strategies at play of agents that were for and
against the development
and deployment of the system. And The Summit provides a
key piece of the history of our global economic CAS.
Bretton woods |
A key agent in the 1990 - 2008
housing expansion Countrywide is linked into the residential
mortgage value delivery system (VDS)
by Paul Muolo and Mathew Padilla. But they show the VDS
was full of amplifiers and control points. With no one
incented to apply the brakes the bubble grew and burst.
Following the summary of Muolo and Padilla's key points the
complex adaptive system (CAS)
aspects are highlighted.
Housing amplifiers |
Satyajit Das uses an Indonesian company's derivative trades to
introduce us to the workings of the international derivatives
system. Das describes the components of the value delivery
system and the key
transactions. He demonstrates how the system
interacted with emerging economies
expanding them, extracting profits and then moving on as the
induced bubbles burst. Following Das's key points the
complex adaptive system (CAS)
aspects are highlighted.
Derivative systems |
Johnson & Kwak argue that expanding the national debt
provides a hedge against unforeseen future problems, as long as
creditors are willing to continue lending. They illustrate
different approaches to managing the debt within the US over its history and of the
eighteenth century administrations of England and France.
The US embodies two different political and economic systems which
approach the national debt differently:
- Taxes to support a sinking
fund to ensure credit to leverage fiscal power in:
Wars, Pandemics, Trade disputes, Hurricanes, Social
programs; Starting with Hamilton,
Lincoln & Chase,
Wilson, FDR;
- Low taxes, limited infrastructure, with risk assumed by
individuals: Advocated by President's Jefferson & Madison,
Reagan,
George W. Bush (Gingrich);
Johnson & Kwak develop a model of what the US
government does. They argue that the conflicting
sinking fund and low tax approaches leaves the nation 'stuck in
the middle' with a future problem.
And they offer their list of 'first principles' to help
assess the best approach for moving from 2012 into the
future.
They conclude the question is still political. They hope
it can be resolved with an awareness of their detailed
explanations. They ask who is willing to
push all the coming risk onto individuals.
Following our summary of their arguments RSS frames them from the
perspective of complex adaptive system (CAS) theory.
Historically developing within the global cotton value delivery
system, key CAS features are highlighted.
National debt |
Robert Gordon argues that the inventions of the second
industrial revolution were the foundation for
American economic growth. Gordon shows how flows of people
into difficult rural America built a population base
which then took the opportunity to move on to urban settings: Houses, Food in supermarkets,
Clothes in
department stores;
that supported increasing productivity and standard of living.
The deployment of nationwide networks: Rail, Road, Utilities;
terminating in the urban housing and work places allowing the workers to
leverage time saving goods and services, which helped grow
the economy.
Gordon describes the concomitant transformation of:
- Communications
and advertising
- Credit
and finance
- Public
health and the health
care network
- Health insurance
- Education
- Social
and welfare services
Counter intuitively the constraints
introduced before and in the Great Depression and the demands of World War 2
provide the amplifiers that drive the inventions deeply and
fully into every aspect of the economy between 1940 and 1970
creating the exceptional growth and standard of living of post
war America.
Subsequently the
rate of growth was limited until the shift of women
into the workplace and the full networking of
voice and data supported the Internet and World Wide Web
completed the third industrial revolution, but the effects were
muted by the narrow reach of the technologies.
The development of Big Data, Robots,
and Artificial Intelligence may support additional growth,
but Gordon is unconvinced because of the collapse of
the middle class.
Following our summary of Gordon's book RSS frames his arguments from
the perspective of complex adaptive system (CAS) theory.
American growth |
Carl Menger argues that the market induced the emergence of
money based on the attractive features of precious metals.
He compares the potential for government edicts to create money
but sees them as lacking.
Following our summary of his arguments RSS frames his arguments from
the perspective of complex adaptive system (CAS) theory.
With two hundred years of additional knowledge we conclude that
precious metals are not as attractive as Menger asserts.
Government backed promissory notes are analogous to:
- Other evolved CAS forms of ubiquitous high energy
transaction intermediates and
- Schematic strategies that are proving optimal in
supporting survival and replication in the currently
accessible niches.
Emergence of money |
Eric Beinhocker sets out to answer a question Adam Smith
developed in the Wealth of Nations: what is wealth? To do
this he replaces traditional
economic theory, which is based on the assumption that an
economy is a system in
equilibrium, with complexity
economics in which the economy is modeled as a complex
adaptive system (CAS).
He introduces Sugerscape
to illustrate an economic CAS model in action. And then he
explains the major features of a CAS economy: Dynamics,
Agents, Networks, Emergence, and
Evolution.
Building on complexity economics Beinhocker reviews how evolution applies to
the economy to build wealth. He explains how design spaces
map strategies to instances of physical and
social
technologies. And he identifies the interactors and
selection mechanism of economic
evolution.
This allows Beinhocker to develop a new definition
of wealth.
In the rest of the book Beinhocker looks at the consequences of
adopting complexity economics for business and society: Strategy, Organization, Finance,
& Politics
& Policy.
Following our summary of his arguments, RSS explores his conclusions
and aligns Beinhocker's model of CAS with the CAS theory and evidence we
leverage.
Economic complexity |
Sven Beckert describes the historic transformation of the
growing, spinning, weaving, manufacture of cotton goods and
their trade over time. He describes the rise of a first global
commodity, its dependence on increasing: military power, returns for
the control points in the value delivery system(VDS), availability of land
and labor to work it including slaves.
He explains how cotton offered the opportunity for
industrialization further amplifying the productive capacity of
the VDS and the power of the control points. This VDS was quickly
copied. The increased capacity of the industrialized
cotton complex adaptive system (CAS) required more labor to
operate the machines. Beckert describes the innovative introduction of wages
and the ways found to
mobilize industrial labor.
Beckert describes the characteristics of the industrial cotton
CAS which made it flexible enough to become globally interconnected.
Slavery made the production system so cost effective that all
prior structures collapsed as they interconnected. So when
the US civil war
blocked access to the major production nodes in the
American Deep South the CAS began adapting.
Beckert describes the global
reconstruction that occurred and the resulting destruction of the traditional ways
of life in the global countryside. This colonial expansion
further enriched and empowered the 'western' nation states. Beckert explains
how other countries
responded by copying the colonial strategies and creating
the opportunities for future armed conflict among the original
colonialists and the new upstarts.
Completing the adaptive
shifts, Beckert describes the advocates for industrialization in
the colonized global south and how over time they joined
the global cotton CAS disrupting the early western manufacturing
nodes and creating the current global CAS
dominated by merchants like Wal-Mart
pulling goods through a network of clothing manufacturers,
spinning and weaving factories, and growers competing with each
other on cost.
Following our summary of Beckert's book, RSS comments from the
perspective of CAS theory. The transformation of
disconnected peasant farmers,
pastoral warriors and their lands into a supply chain for a
highly profitable industrial CAS required the development over
time: of military force, global transportation and communication
networks, perception and representation control networks, capital stores and flows,
models, rules, standards and markets; along with the support at
key points of: barriers, disruption, and infrastructure and
evolved amplifiers. The emergent
system demonstrates the powerful constraining influence of
extended phenotypic alignment.
Globalization from cotton |
The structure and problems of the US
health care network is described in terms of complex adaptive
system (CAS) theory.
The network:
- Is deeply embedded in the US nation
state. It reflects the conflict between two
opposing visions for the US: high tax with safety net
or low tax without. The emergence
of a parasitic elite supported by tax policy, further
constrains the choices available to improve the efficiency
and effectiveness of the network.
- The US is optimized to sell its citizens dangerous
levels of: salt,
sugar, cigarettes,
guns, light, cell phones, opioids,
costly education, global travel,
antibacterials, formula, foods including
endocrine disrupters;
- Accepting the US controlled global supply chain's
offered goods & services results in: debt, chronic stress,
amplified consumption and toxic excess, leading to obesity, addiction, driving instead of
walking, microbiome
collapse;
- Globalization connects disparate environments in a network. At the edges,
humans are drastically altering the biosphere. That
is reducing the proximate natural environment's
connectedness, and leaving its end-nodes disconnected and
far less diverse. This disconnects predators from
their prey, often resulting in local booms and busts that
transform the local parasite
network and their reservoir and amplifier
hosts. The situation is setup so that man is
introduced to spillover
from the local parasites' hosts. Occasionally, but
increasingly, the spillover results in humanity becoming
broadly infected. The evolved
specialization of the immune system
to the proximate environment during development
becomes undermined as the environment transforms.
- Is incented to focus on localized competition generating
massive & costly duplication of services within
physician based health care operations instead of proven
public health strategies. This process drives
increasing research & treatment complexity and promotes hope
for each new technological breakthrough.
- Is amplified by the legislatively structured separation
and indirection of service development,
provision, reimbursement and payment.
- Is impacted by the different political strategies for
managing the increasing
cost of health care for the demographic bulge of retirees.
- Is presented with acute
and chronic
problems to respond to. As currently setup the network
is tuned to handle acute problems. The interactions
with patients tend to be transactional.
- Includes a legislated health insurance infrastructure
which is:
- Costly and inefficient
- Structured around yearly
contracts which undermine long-term health goals and
strategies.
- Is supported by increasingly regulated HCIT
which offers to improve data sharing and quality but has
entrenched commercial EHR
products deep within the hospital systems.
- Is maintained, and kept in
alignment, by massive network
effects across the:
- Hospital platform
based
sub-networks connecting to
- Physician networks
- Health insurance networks - amplified by ACA
narrow network legislation
- Hospital clinical supply and food
production networks
- Medical school and academic research network and NIH
- Global
transportation network
- Public health networks
- Health care IT supply
network

Problems of US health care |
Glenn Steele & David Feinberg review the development of the
modern Geisinger healthcare business after its near collapse
following the abandoned merger with Penn State AMC. After an overview of the
business, they describe how a calamity
unfolding around them supported building a vision of a
better US health care network. And they explain:
- How they planned
out the transformation,
- Leveraging an effective
governance structure,
- Using a strategy
to gain buy in,
- Enabling
reengineering at the clinician patient
interface.
- Implementing the reengineering for acute, chronic
& hot
spot care; to help the patients and help the
physicians.
- Geisinger's leverage of biologics.
- Reengineering healing with ProvenExperience.
- Where Geisinger is headed next.
Following our summary of their arguments RSS comments on them. We
frame their ideas with complex adaptive system (CAS)
theory.
E2E insured quality care |
Robert Pearl explains the perspectives of a health care leader
and son who know that the current health care network interacts
with human behavior to induce a poorly performing system that
caused his father's death. But he is confident that these
problem perceptions can be changed. Once that occurs he
asserts the network will become more integrated, coordinated,
collaborative, better led, and empathetic to their
patients. The supporting technology infrastructure will be
made highly interoperable. All that will reduce medical
errors and make care more cost effective.
Following our summary of his arguments RSS comments on them. We
frame his ideas with complex adaptive system (CAS) theory
including synergistic examples of these systems in
operation. The health care network is built out of
emergent human agents. All agents must model the signals
they perceive to represent and respond to them. Pinker
explains how this occurs. Sapolsky explains why fear and
hierarchy are so significant. He includes details of Josh
Green's research on morality and death. Charles Ferguson
highlights the pernicious nature of financial incentives.
Bad medical models |
US healthcare is ripe for
disruption. Christensen, Grossman and Hwang argue that
technologies are emerging which will support low cost business
models that will undermine the current network. Applying
complex adaptive system (CAS)
theory to these arguments suggests that the current power hierarchy can effectively resist
these progressive forces.
Disrupting health care |
Atul Gawande writes about the opportunity for a thirty per cent
improvement in quality in medicine by organizing
to deploy as agent based teams using shared schematic
plans and distributed signalling or as he puts it the use of checklists.
With vivid examples from a variety of situations including construction, air crew support and global health care Gawande illustrates
the effects of
complexity and how to organize to cope with it.
Following the short review RSS
additionally relates Gawande's arguments to its models of
complex adaptive systems (CAS) positioning his discussion within
the network of US health care,
contrasting our view of complexity, comparing the forces shaping
his various examples and reviewing facets of complex
failures.
Complexity checklists |
Friedman and Martin leverage the lifelong data collected on
1,528 bright individuals selected by Dr. Lewis Terman
starting in 1921, to understand what aspects of the subjects'
lives significantly affected their longevity. Looking
broadly across each subject's: Personality,
Education, Parental impacts,
Energy
levels, Partnering,
Careers, Religion,
Social networks,
Gender, Impact from war and
trauma; Friedman and Martin are able to develop a set of model pathways,
which each individual could be seen to select and travel
along. Some paths led to the traveler having a long
life. Others were problematic. The models imply that
the US approach to health and
wellness should focus
more on supporting
the development and selection of beneficial pathways.
Following our summary of their arguments RSS comments from the
perspective of CAS theory. The pathways are most
applicable to bright individuals with the resources and support
necessary to make and leverage choices they make. Striving
to enter and follow a beneficial pathway seems sensible but may
be impossible for individuals trapped in a collapsing network,
starved of resources.
Promoting longevity |
Gawande uses his personal experience, analytic skills and lots
of stories of innovators to demonstrate better ways of coping
with aging and death. He introduces the lack of focus on
aging and death in traditional medicine. And goes on to
show how technology has amplified
this stress point. He illustrates the traditional possibility of the
independent self, living fully while aging with the
support of the extended family. Central
planning responded to the technological and societal changes
with poorly designed infrastructure and funding. But
Gawande then contrasts the power of
bottom up innovations created by experts responding to
their own family situations and belief
systems.
Gawande then explores in depth the challenges
that unfold currently as we age and become infirm.
He notes that the world is following the US path. As such it will
have to understand the dilemma of
integrating medical treatment and hospice
strategies. He notes that all parties
involved need courage to cope.
He proposes medicine must aim to assure
well being. At that point all doctors will practice
palliative care.
Complex adaptive system (CAS) models of agency, death,
evolution, cooperation and adaptations
to new technologies are discussed.
Agent death |
Sonia Shah reviews the millennia old (500,000 years) malarial arms race between Humanity, Anopheles

Using John Holland's theory of adaptation in complex
systems Baldwin and Clark propose an evolutionary theory of
design. They show how this can limit the interdependencies
that generate complexity
within systems. They do this through a focus on
modularity.
Modular designed systems |
Lou Gerstner describes the challenges he faced and the
strategies he used to successfully restructure the computer
company IBM.
Compartmented systems |
Grady Booch advocates an object oriented approach to computer
software design.
Object based systems |
Bertrand Meyer develops arguments, principles and strategies for
creating modular software. He concludes that abstract data
types and inheritence make object orientation a superior
methodology for software construction. Complex adaptive
system (CAS) theory suggests agents provide an alternative strategy
to the use of objects.
Software construction |
Joseph Tainter introduces
the problem of collapse and then develops a theory of complexity and
reviews prior theories of collapse
of societies. He then builds a general
explanation of collapse and explains declining
marginal returns in significant aspects of complex societies,
and evaluates the theory by examining its
applicability to historical examples. He then subsumes other explanatory
themes into his marginal
returns logic and applies it to our current situation.
Following our summary of his arguments, RSS frames these from the
perspective of complex adaptive system (CAS) theory: CAS entities provide an effective emergence and
collapse point. The history of
events which results in each emergence point Tainter reviews
introduces constraints
on the aggregate entity. These constraints can help
define the emergence and collapse point and remove
inconsistencies from the analytic framework. Tainter's economic framework,
conforming to the equilibrium proposed by Walras and Jevons, can
benefit from alignment with complexity
economics.
Fall of societal entities |
Tools and the businesses that produce them have evolved
dramatically. W Brian Arthur shows how this occurred.
Tools |
Matt Ridley demonstrates the creative effect of man on the
World. He highlights:
- A list of
preconditions resulting in
- Additional niche
capture & more free time
- Building a network
to interconnect memes processes & tools which
- Enabling inter-generational
transfers
- Innovations
that help reduce environmental stress even as they leverage fossil
fuels
Memetic trading networks |
E O. Wilson argues that campfire gatherings on the savanna supported
the emergence of human creativity. This resulted in man
building cultures and
later exploring them, and their creator, through the humanities. Wilson
identifies the transformative events, but he notes many of these
are presently ignored by the humanities. So he calls for a
change of approach.
He:
- Explores creativity:
how it emerged from the benefits of becoming an omnivore hunter-gatherer,
enabled by language & its catalysis of invention, through stories told in the
evening around the campfire. He notes the power of
fine art, but suggests music provides the most revealing
signature of aesthetic
surprise.
- Looks at the current limitations of the
humanities, as they have suffered through years of neglect.
- Reviews the evolutionary processes of heredity and
culture:
- Ultimate causes viewed
through art, & music
- The bedrock of:
- Ape senses and emotions,
- Creative arts, language, dance, song typically studied
by humanities,
&
- Exponential change in science and
technology.
- How the breakthrough from
our primate past occurred, powered by eating meat,
supporting: a bigger brain, expanded memory &
language.
- Accelerating changes now driven by genetic cultural coevolution.
- The impact on human nature.
- Considers our emotional attachment to the natural world: hunting, gardens; we are
destroying.
- Reviews our love of metaphor, archetypes,
exploration, irony, and
considers the potential for a third enlightenment,
supported by cooperative
action of humanities and science
Following our summary of his arguments RSS frames these from the
perspective of complex adaptive system (CAS) theory:
- The humanities are seen to be a functionalist framework
for representing the cultural CAS while
- Wilson's desire
to integrate the humanities and science gains support from
viewing the endeavor as a network of layered CAS.
Evening campfire rituals |
Brynjolfsson and McAfee explore the effects of Moore's law on the
economy. They argue it has generated exponential
growth. This has been due to innovation.
It has created a huge bounty of
additional wealth.
But the wealth is spread unevenly across
society. They look at the short and long term implications of
the innovation bounty and spread
and the possible future of
technology.

Brilliant technologies |
Salman Khan argues that the evolved global education system is
inefficient and organized around constraining and corralling
students into accepting dubious ratings that lead to mundane
roles. He highlights a radical and already proven
alternative which offers effective self-paced deep learning
processes supported by technology and freed up attention of
teams of teachers. Building on his personal experience of
helping overcome the unjustified failing grade of a relative,
Khan:
- Iteratively learns how to teach: Starting with Nadia, Leveraging

change but if its force is used to support the current teachers
to adopt new processes can it overcome the extended phenotypic alignment and evolutionary amplifiers sustaining the

Peter Turchin describes how major pre-industrial empires
developed due to effects of geographic boundaries constraining
the empires and their neighbors' interactions. Turchin
shows how the asymmetries of breeding rates and resource growth
rates results in dynamic cycles within cycles. After the

E. O. Wilson & Bert Holldobler illustrate how bundled cooperative strategies can
take hold. Various social insects have developed
strategies which have allowed them to capture the most valuable
available niches. Like humans they invest in
specialization and cooperate to subdue larger, well equipped
competitors.

The stages of development of the human female, including how her brain changes and the
impacts of this on her 'reality' across a full life span:
conception, infantile
puberty, girlhood,
juvenile pause, adolescence, dating years, motherhood, post-menopause; are
described. Brizendine notes the significant difference in
how emotions are processed
by women compared to men.
Complex adaptive system (CAS) theory associates the stages with
the evolutionary under-pinning, psychological implications and
behavioral CAS.

The complexity of behavior is explored through Sapolsky
developing scenarios of our best and worst behaviors across time
spans, and scientific subjects including: anthropology,
psychology, neuroscience, sociology. The rich network of adaptive flows he
outlines provides insights and highlight challenges for
scientific research on behavior.
Complex adaptive system (CAS) theory builds on Sapolsky's
details highlighting the strategies that evolution has captured
to successfully enter niches we now occupy.

Carlo Rovelli resolves the paradox of time.
Rovelli initially explains that low level physics does not
include time:
- A present that is common throughout the universe does not exist
- Events are only partially ordered. The present is
localized
- The difference between past and future is not foundational.
It occurs because of state that through our blurring appears
particular to us
- Time passes at different speeds dependent on where we are and how fast we travel
- Time's rhythms are due to
the gravitational field
- Our quantized physics shows neither
space nor time, just processes transforming physical
variables.
- Fundamentally there is no time. The basic equations
evolve together with events, not things
Then he
explains how in a physical world without time its perception can
emerge:
- Our familiar time emerges
- Our interaction with the world is partial, blurred,
quantum indeterminate
- The ignorance determines the existence of thermal time
and entropy that quantifies our uncertainty
- Directionality of time is real
but perspectival. The entropy of the world in
relation to us increases with our thermal time. The
growth of entropy distinguishes past from future: resulting in
traces and memories
- Each human is a
unified being because: we reflect the world, we
formed an image of a unified entity by
interacting with our kind, and because of the perspective
of memory
- The variable time: is one
of the variables of the gravitational field.
With our scale we don't
register quantum fluctuations, making space-time
appear determined. At our speed we don't perceive
differences in time of different clocks, so we experience
a single time: universal, uniform, ordered; which is
helpful to our decisions
Emergence of time |
Consciousness has confounded philosophers and scientists for
centuries. Now it is finally being characterized
scientifically. That required a transformation of
approach.
Realizing that consciousness was ill-defined neuroscientist
Stanislas Dehaene and others characterized and focused on conscious access.
In the book he outlines the limitations of previous
psychological dogma. Instead his use of subjective
assessments opened the
window to contrast totally unconscious
brain activity with those
including consciousness.
He describes the research methods. He explains the
contribution of new sensors and probes that allowed the
psychological findings to be correlated, and causally related to
specific neural activity.
He describes the theory of the brain he uses, the 'global neuronal
workspace' to position all the experimental details into a
whole.
He reviews how both theory and practice support diagnosis and
treatment of real world mental illnesses.
The implications of Dehaene's findings for subsequent
consciousness research are outlined.
Complex adaptive system (CAS) models of the brain's development and
operation introduce constraints which are discussed.
Conscious access |
Reading and writing present a conundrum. The reader's
brain contains neural networks tuned to reading. With
imaging a written word can be followed as it progresses from the
retina through a functional chain that asks: Are these letters?
What do they look like? Are they a word? What does it sound
like? How is it pronounced? What does it mean? Dehaene
explains the importance of
education in tuning the brain's networks for reading as
well as good strategies for teaching reading and countering dyslexia. But
he notes the reading
networks developed far too recently to have directly evolved.
And Dehaene asks why humans are unique in developing
reading and culture.
He explains the cultural
engineering that shaped writing to human vision and the exaptations and neuronal structures that
enable and constrain reading and culture.
Dehaene's arguments show how cellular, whole animal and cultural
complex adaptive system (CAS) are
related. We review his explanations in CAS terms and use
his insights to link cultural CAS that emerged based on reading
and writing with other levels of CAS from which they emerge.
Evolved reading |
Read Montague explores how brains make decisions. In
particular he explains how:
- Evolution can create indirect abstract models, such as the dopamine system, that
allow
- Life changing real-time
decisions to be made, and how
- Schematic structures provide
encodings of computable control
structures which operate through and on incomputable,
schematically encoded, physically active structures and
operationally associated production
functions.

Daniel Goleman and Richard Davidson describe a scientific
investigation of meditation's
impact on the brain. They introduce
the book by describing their experiences with meditation,
science and the research establishment, their friendship, how
meditation is now used in two distinct ways: deep - leading to altered
traits & wide - that can reach the multitudes; which
the book reviews as it critiques the claims and research used to
back them up.
Goleman and Davidson describe meeting as Harvard psychology
graduate students, interested in consciousness, and how minds
work. They rebel against the behavioral orthodoxy, visit Asia and discover the Eastern
tradition of exploring and altering the mind.
Goleman had travelled to Sri Lanka to understand an Asian model
of the mind, which he presented to the undergraduates at
Harvard. Goleman and Davidson developed it into a shared vision of
consciousness. It took over twenty years for
scientific theory and experimental data to catch up and align
with this model. Much of the prior
experimental data had to be abandoned.
They introduce meditation's
impact on the amygdala
responding to pain and stress.
They look at the changes in:
- Stress
- Compassion
- Attention
- Self-awareness; and the
potential for use of mediation
in psychiatry.
And they warn of the occurrence of dark
nights.
They detail how scientists were able to study the brains of Tibetan meditation masters,
starting with Mingyur Rinpoche,
and detect meditation altering
traits.
Finally they discuss the potential
benefits of meditation and strategies to distribute it
broadly to a busy America.

Tara Brach was worried from
a young age that there was something terribly wrong with
her: she like many others felt unworthy. She responded
by developing Radical
Acceptance. Brach then explains the steps in
applying it: pause,
greet what happens next with unconditional
friendliness; allowing us to:
- Initially attend to the sensations
of our body,
- Accept the
wanting self and discover its source of boundless
love.
- Welcome
fear with a widening
attention, accept the pain of death and become
free.
- Use adversity as a gateway to limitless compassion for ourselves
and others.
- Focus on
our basic goodness to counter Western culture turning anger, at being betrayed,
towards ourselves. Extend observing this goodness in
everyone. This enables the use of loving-kindness.
- Leverage
friendships to understand more about our shared nature
and strengthen Radical Acceptance.
- Realize our Buddha nature.
Complex adaptive system (CAS) theory describes the emergence of
the dualistic self and the tree of life linked by the genetic
code and machinery. It provides an analog of the Buddhist
presence.
Compassionate CAS |
The influence of childhood on behavior is significant.
Enneagrams define personality
types: Reformer, Helper, Achiever,
Individualist, Investigator, Loyalist, Enthusiast,
Challenger and Peacemaker; based on the impact of
childhood driven wounds.
The Enneagram becomes
a tool to enable interested people to transform from the
emotionally wounded base, hidden within
the armor of the type, to the liberated underlying essence.
Childhood leaves each of us with some environmentally specific Basic Fear. In response each
of us adopts an induced Basic Desire
of the type. But as we develop the inner observer, it will
support presence and
undermine the identification
that supports the armor of the type.
The Enneagram reveals three sets of relations about our type
armor:
- Triadic self
revealing: Instinctive,
feeling, thinking; childhood needs
that became significant wounds
- Social style
groupings: Assertive, compliant, withdrawn; strategies for
managing inner conflict
- Coping styles: Positive outlook, competency, reactive; strategies for
defending childhood wounds
Riso and Hudson augment the Enneagram with instinctual
distortions reflected in the interests of the variants.
The Enneagram also offers tools for understanding a person's level of development:
unhealthy, average, healthy,
liberation; including their
current center of gravity,
steriotypical social role,
wake-up call, leaden rule, red
flag, and direction
of integration and disintegration.
Complex adaptive system (CAS) theory associates the models
presented by the Enneagram with evolved behaviors and structures
in the mind: feelings, emotions, social behaviors, ideas; driven
by genetic and cultural evolution and the constraints of family
and social life. Emergent evolved amplifers can be
constrained by Riso and Hudson's awareness strategies.
Enneagram strategies |
Antonio Damasio argues
that ancient
& fundamental homeostatic processes,
built into
behaviors and updated by evolution
have resulted in the emergence
of nervous systems and feelings. These
feelings, representing the state of the viscera, and represented with general
systems supporting enteric
operation, are later ubiquitously
integrated into the 'images'
built by the minds of higher animals
including humans.
Damasio highlights the separate
development of the body frame in the building of
minds.
Damasio explains that this integration of feelings by minds
supports the development of subjectivity and consciousness. His chain of
emergence suggests the 'order of things.' He stresses the
end-to-end
integration of the organism which undermines dualism. And he reviews Chalmers
hard problem of consciousness.
Damasio reviews the emergence of cultures
and sees feelings, integrated with reason, as the judges of the
cultural creative process, linking culture to
homeostasis. He sees cultures as supporting the
development of tools
to improve our lives. But the results of the
creative process have added
stresses to our lives.
Following our summary of his arguments RSS frames his arguments from
the perspective of complex adaptive system (CAS) theory.
Each of the [super]organisms
discussed is a CAS reflecting the theory of such systems:
- Damasio's proposals about homeostasis routed signalling, aligns
well with CAS theory.
- Damasio's ideas on cultural stresses are elaborated by CAS
examples.
Emergence of feelings |
Robert Coram highlights the noble life of John Boyd. John
spent a lot of time alone
during his childhood.
He: excelled at swimming and was a lifeguard, enlisted in the
Army Air Corp while at school which rejected him for pilot
training, was part of the Japan occupation force where he swam;
so the US paid for him to attend University
of Iowa, where he: joined the Air Force Officers' training
corps, was accepted to be an Air Force pilot, and got engaged to
Mary Bruce.
Boyd trained at Nellis AFB to become a
combat ready pilot in
the Korean War.
While the US Air Force focused on
Strategic bombing, Boyd loved
dogfights. His exceptional tactical ability was
rewarded with becoming an instructor. Boyd created new
ways to think about dogfighting and beat all-comers
by using them in the F-100.
He was noticed and enabled by Spradling. As he trained, and defeated the top
pilots from around the US and allied base network, his
reputation spread. But he needed to get
nearer to the hot spring in Georgia, and when his move to
Tyndall AFB was blocked he used the AFIT to train in engineering at
Georgia tech. While preparing to move he documented his FWS training
and mentored Ronald Catton.
While there he first realized the
link between energy
and maneuverability.
At Eglin, in partnership with Tom Christie,
he developed tools to model the link. They developed
comparisons of US and Soviet aircraft which showed the US
aircraft performing poorly. Eventually General Sweeney
was briefed on
the theory and issues with the F-105, F-4, and F-111.
Sent to the Pentagon
to help save the F-X budget, Boyd joined forces with Pierre Sprey to
pressure procurement into designing and
building tactically exceptional aircraft: a CAS tank killer and a
lightweight maneuverable
fighter. The navy aligned with
Senators of states with navy bases, prepared to sink the
F-X and force the F-14 on
the Air Force. Boyd saved
the plane from the Navy and the budget from Congress, ensuring
the Air Force executive and its career focused hierarchy had the
freedom to compromise
on a budget expanding over-stuffed F-X (F-15). Boyd requested to
retire, in disgust.
Amid mounting hostility from the organizational hierarchy Boyd
and Sprey secretly
developed specifications for building prototype lightweight
fighters with General Dynamics: YF-16;
and Northrop: YF-17; and enabled by Everest Riccioni.
David Packard
announced a budget of $200 million for the services to spend on
prototypes. Pierre Sprey's friend Lyle Cameron picked a
short takeoff and landing transport aircraft and Boyd's lightweight fighter to
prototype.
Boyd was transferred to Thailand
as Vice Commander of Task
Force Alpha, inspector general and equal opportunity
training officer; roles in which he excelled. And he
started working on his analysis of creativity: Destruction
and Creation. But on completion of the tour Boyd was
apparently abandoned and sent to run
a dead end office at the Pentagon.
The power hierarchy moved to protect the F-15, but: Boyd,
Christie, Schlesinger,
and the Air Force chief of staff; kept the
lightweight fighter budgeted and aligned with Boyd's
requirements in a covert campaign. The Air Force
threw a phalanx of developers at the F-16, distorting Boyd's
concept. He accepted he had lost the fight and retired
from the Air Force.
Shifting to scholarship Boyd reflects on how rigidity must be destroyed to enable
creative new assemblies. He uses the idea to explain
the operational success of the YF16 and F-86 fighters, and then
highlights how the pilot can take advantage of their
infrastructure advantage with rapid decision making he
explains with the O-O-D-A Loop.
Boyd encouraged Chuck Spinney
to expose the systemic cost overruns
of the military procurement process. The military
hierarchy moved to undermine the
Spinney Report and understand the
nature of the reformers. Boyd acted as a progressive
mentor to Michael
Wyly, who taught the
Marine Corps about maneuver
warfare, and Jim Burton.
Finally, after the military hierarchy appears to have
beaten him, Boyd's ideas are tested during
the First Gulf War.
Following our summary of his main points, RSS frames the details from the
perspective of complex adaptive system (CAS) theory. Boyd was Darwinesque, placing the art of
air-to-air combat within a CAS framework.

Reginald Dwight, better known as Elton John, writes a hilarious
memoir, full of anecdotal and sometimes morbid humor and gossip, which describes his
immediate family, upbringing, development as a singer
songwriter, stardom and its support for his problems, collapse
and eventual recovery.
Elton stresses the serendipitous nature
of his emergence as a musician. He describes
the contributions of his parents, Stanley & Sheila, mother's
sister, and her mother Ivy;
who formed his early
childhood proximate environment which prepared
him for a job in entertainment: he
developed his performance in the club circuits, setup a
commercial partnership with Bernie Taupin to write songs;
entering a network based around Dick James Music.
And he almost got married.
DJM focused Elton and Bernie's initial song writing
while they studied the songs they admired and Elton did session
work, tightening his performance skills and paying for the
food. A first album supported touring and the formation of
a band. A second one sent them to the US where Elton became an
overnight sensation. And during this period of time
Elton's testosterone
level ramped. Life changed
dramatically.
Stardom provided many rewards but there
were still life's problems to deal with. Elton was
befriended by his idol, John Lennon; he achieved new heights of
success but, sensitive to any hint of failure and fraud, suicidally disassociated.
His career crested, he struggled with loneliness and drugs, and
foresaw a fearful vision of his future, as fame caged him idly
in hotels between concerts. His hair abandoned him.
But he was saved by the challenge of
transforming the collapsed Watford football club. He
retired from touring which allowed him the time to reconstruct his life.
Empowered by success, supported by the removal of constraints,
Elton dominates - limiting feedback, doing whatever he
hopes will bring him happiness:
trying new options, expanding the range and increasing the
quantity of mind altering substances; eventually hitting John Reid and marrying
Renata.
He allows his drug use to enter the recording studio. Problems stress him. He is
frightened by a cancer
scare, AIDS, inspired by
Ryan White, angered by the
Sun, and saddened at
breaking Renata's heart. But he was there for Ryan White's
final days. And his lover Hugh Williams confronted Elton
about his string of addictions.
Elton finally agreed he had a problem.
He went to rehab, stopped hating himself,
gave up his current addictions, accepted the influence of a
higher force, and began admiring the everyday world and other
people.
It seemed the higher force was
supporting Elton's progress: he wrote the music for the
Lion King, met David Furnish who accepted Elton warts and all;
they both enjoyed a friendship with Gianni Versace; until Gianni
was murdered. Princess Diana
died soon after, and Elton performed at the funeral.
He toured with Billy Joel and aimed to do the same with Tina
Turner. While his new records sold well he found
himself in debt and terminated the management relationship
with John Reid
Enterprises.
Elton and Bernie improved their
situations: Elton started writing film scores, he helped
turn the film Billy Elliot into a musical, Bernie lobbied Elton
to improve the way they were making records, Elton and David
entered into a civil partnership, and Elton made a record with
his seminal influence: Leon
Russell.
Elton and David became parents of
two boys: Zachary and Elijah; using their sperm a surrogate
mother and network in California. They quietly get married
when the UK allows.
Elton's mum remains
difficult and cruel to him, but he is sad when she dies, and many
at the funeral recall her fun side with him. Being parents
increases the long-term
stresses on their lives, forcing them to adjust, so they can be there for their boys.
But Elton needs to go out with a bang!
And everyone helps.

Bob Iger writes about his leadership strategies based on his
life experiences, which describes his immediate family,
upbringing, development
as a weatherman,
production studio
supervisor, divisional: ABC Television,
Disney Media - where he had the
challenge of integrating a centralized and a distributed
corporate culture; and enterprise leader at ABC, Capital Cities and Disney: COO, and CEO.
He describes the struggle
Disney CEO Eisner had with giving Iger the COO role, explaining
how he learned to approach this challenge. When the board
concluded Disney was floundering and forced out Eisner, Iger had to convince them he
was the solution to their dilemma.
Iger was chosen as the
next CEO by the board but also had to convince Roy Disney,
and signal the world that he could revitalize the company and partner with
Steve Jobs.
Jobs was a catalyst in Iger's
acquisition of Marvel, and
Lucas Film, and he became a friend and advisor who died
too young.
Iger had to
respond to the disruption of Disney's mainline
businesses. He transformed Disney's loose aggregate of
businesses into a platform based on BAMTech's streaming media
platform which supported the delivery of emotionally charged
content direct to the consumer.
Rupert Murdoch agreed with Iger's response to the disruptive
environment and decided
to sell Fox to Disney, but there
were complications.
Following our summary of his main points, RSS places Iger's creations
within the phalanx of global forces buffeting Disney using the perspective
of complex adaptive system (CAS) theory.
Bob's global technology marvel |
Richard Feynman
outlines a series of amusing vignettes, as he reviews his life story.
Richard's personality
encouraged him to patiently
seek out fun: performing Shewhart cycles
with electricity, in his childhood laboratory, and aligning theory, and
practice through building and fixing radios.
Leonardo's life inspired him to try
innovation, which he
concluded was hard. He played
with the emotion
in communications, a skill
which he used later at
Caltech. And he made a game of avoiding following
orders at MIT. Working during
the holidays revealed the benefit of joining theory and
practice.
Feynman enrolled as a graduate
student at Princeton, where the successful
approach to science was just like his.
His approach was based on
patience and fun: he used his home lab and other tools for
qualitative exploration. Overtime he added experimental
techniques. He would test
the assertions in articles with amusing investigations;
with his mind aligned by
feelings of joy. Everyone at Princeton heard he would want to be hypnotized.
He was driven to compare the challenges of complex subjects being
taught at Princeton to his current pick. In his summer
recess he explored biology.
Gathering problems in challenging areas of science, and then picking one to solve, supported his
creativity. And his practical
orientation and situation when growing up in Far Rockaway,
supported his desire for choices
and adolescent dislike for purely intellectual and cultural
pursuits. Being mostly self-taught, he
developed different approaches to problems than the
standard strategies provided by mass education.
Richard saw his skill set as very different to that exhibited by his father. But are they very
different?
While Richard was at Princeton, America became concerned about
the implications of the European war. After a friend
enlisted he decided to dedicate his
summer holiday to helping the war effort. Feynman got involved in the
Manhattan Project, and went to Los Alamos where he
experienced constraints, applied by: the military, the
physics of the project, him on Niels
Bohr; but was
freed from them by Von
Neumann. The records & reports of the project
were kept in filing cabinets. Richard explored the weaknesses of
the locks and safes deployed to secure these
secrets. Just after the war he was called up by the draft
board for a medical but was rejected for being mentally
unfit.
After the war, Richard was asked to become a professor at Cornell.
He initially struggled in this role: Too young to match
expectations, stressed by the demands of his new job and his
recent experiences; until he adopted an approach that focused on
fun. He enjoyed knowing
about numbers: using, learning about them and the tools to
use them, and competing with others; to calculate, interpolate
and approximate a value the fastest.
Traveling to Buffalo in a light plane once a week to give a
physics lecture before flying back the next morning wasn't much
fun for Richard. So he used
the stipend to visit a bar after each lecture to meet
beautiful women. Richard liked bars and nightclubs, spending a summer in Albuquerque
frequenting one, and later
ones in Las Vegas, as he explored how to get the girls he
drank with to sleep with him.
Richard reflects on various times when he made government
officials obey their parts of contracts: patent fees, limits on red tape;
Richard became frustrated with his life at Cornell, seeing more
things that interested him on the sunny west coast at Caltech. Both
institutions, and Chicago, offered him incentives to help his decision making,
but Richard began to find reevaluating the alternatives a waste
of time and he saw risks in
a really high salary, deciding he would move to Caltech
and stay there.
Richard is invited to attend a scientific symposium in
Japan. Each of the US attendees is asked to learn a little
Japanese. Richard takes lessons, persists, can converse
effectively, but stops when he
finds the cultural parts of the language conflict with his
individualism.
Richard was unhappy with his achievements in physics. He
felt: slower than his peers, not keeping up or understanding the
latest details, fearful that
he could not cope; as the community
worked to understand the laws of beta decay. But
Martin Block pushed him to question the troubling parity
premise. Encouraged by Oppenheimer the community focused
on parity and failures were discovered in a cascade of
reports. Richard attended a meeting where Lee & Yang
discussed a failure and a theory to explain it. Richard
felt terrified and could not understand what they said.
His sister pushed him to change his attitude: act like a student
having fun, read every
line and equation of their paper; he would understand it.
And he did, as well as developing additional insights about what
was happening and what still seemed conflicted. He
reported his ideas back to the community. After Richard
returned from Brazil he reviewed the confusion of facts with
Caltech's experimental physicists who made him aware of
Gell-mann abandoning another former premise of Beta decay.
Feynman realized his ideas were consistent: fully and simply
describing the details of beta decay. He had identified
the workings of a fundamental law. Years later he was awarded the Nobel
prize for physics. He was conflicted about the prize
and attending the ceremony, but eventually enjoyed the trip,
where he discussed cultural achievement with the Japanese
ambassador.
Richard was interested in the operation of the brain, modeling
it on a digital computer. He explored hallucinations and the reality of
experiences.
Richard lobbies for integrity
in science.
In aspects of his life that weren't focused directly on science,
Richard was quirky. He would tease those who asked for his
help: pushing bargains to their logical conclusion; insisting on everyone keeping to
their part of the agreement. And he paid no attention to the
logistical details of planning. He loved percussion,
playing: drums, bongos, baskets, tables, Frigideira; and became quite a success. He
eventually discovered art could be
fun, and tried to express his joy at the underlying
mathematical beauty of the physical world. He had a great
art teacher. But he discovered although he could
eventually draw well he did not understand art.
Many of the artists he met were fakers, and even the powerful,
who were interested in integrating art and science, did not
understand either subject. He found the situation was
similar in other complex adaptive systems: philosophy, religion and
economics; which he dabbled in for a while but found the
strategies of other people practicing the study of such subjects
made him angry and
disturbed, so he avoided participating in them. It seemed
ironic that he was eventually asked to help in bringing
culture to the physicists!
He discusses issues in teaching creative physics in Brazil. He gets
involved in the California public school text
book selection process which he concluded was totally
broken, but also reveals how his father
provided him with a vision of how our world works,
inspiring his interest in experimentation and physical
theory.
Following our summary of his main points, RSS reviews how his personality, family and cultural history supported
his creative development from the perspective of complex
adaptive system (CAS) theory.
Richard draws |
Desmond & Moore paint a picture of Charles Darwin's life,
expanded from his own highlights:
- His naughty
childhood,
- Wasted
schooldays,
- Apprenticeship with Grant,
- His extramural
activities at Cambridge, walks with Henslow,
life with FitzRoy on the
Beagle,
- His growing
love for science,
- London: geology, journal and Lyell.
- Moving from
Gower Street to Down and writing Origin and other
books.
- He reviewed his position on
religion: the long
dispute with Emma, his
slow collapse of belief
- damnation for unbelievers like his father and brother, inward conviction
being evolved and unreliable, regretting he had ignored his father's
advice; while describing Emma's side of the
argument. He felt happy with his decision to dedicate
his life to science. He closed by asserting after Self &
Cross-fertilization his strength will be
exhausted.
Following our summary of their main points, RSS frames the details from the
perspective of complex adaptive system (CAS) theory. Darwin placed
evolution within a CAS framework, and built a network of supporters whose
complementary skills helped drive the innovation.

Computationally adapted mind
Summary
Computational
theory of the mind describes the aggregate ideas of: Alan Turing, Alan Newell, Herbert Simon, Marvin Minsky, Hilary Putnam & Jerry Fodor; that beliefs and desires are information, bound through sense organ triggered associations with neuronal or other symbolic representations that once triggered give rise to other symbols and muscular actions generating behaviors.

making sense of the objects is a collection of: happenings, occurrences and processes; including emergent entities, as required by relativity, explains Rovelli. But natural selection has improved our fitness by representing this perception, in our minds, as an unchanging thing, as explained by Pinker. Dehaene explains the object modeling and construction process within the unconscious and conscious brain. Mathematicians view anything that can be defined and used in deductive reasoning and mathematical proofs as an object. These mathematical objects can be values of variables, allowing them to be used in formulas.

essential to human prioritizing and decision making integrates situational context, state and signals to prioritize among strategies and respond in a timely manner. It occurs in all animals, including us and our organizations: - Individual human decision making includes conscious and unconscious aspects. Situational context is highly influential: supplying meaning to our general mechanisms, & for robots too. Emotions are important in providing a balanced judgement. The adaptive unconscious interprets percepts quickly supporting 'fast' decision making. Conscious decision making, supported by the: DLPFC, vmPFC and limbic system; can use slower autonomy. The amygdala, during unsettling or uncertain social situations, signals the decision making regions of the frontal lobe, including the orbitofrontal cortex. The BLA supports rejecting unacceptable offers. Moral decisions are influenced by a moral decision switch. Sleeping before making an important decision is useful in obtaining the support of the unconscious in developing a preference. Word framing demonstrates the limitations of our fast intuitive decision making processes. And prior positive associations detected by the hippocampus, can be reactivated with the support of the striatum linking it to the memory of a reward, inducing a bias into our choices. Prior to the development of the PFC, the ventral striatum supports adolescent decision making. Neurons involved in decision making in the association areas of the cortex are active for much longer than neurons participating in the sensory areas of the cortex. This allows them to link perceptions with a provisional action plan. Association neurons can track probabilities connected to a choice. As evidence is accumulated and a threshold is reached a choice is made, making fast thinking highly adaptive. Diseases including: schizophrenia and anorexia; highlight aspects of human decision making.

Levitin showed that listening to music causes a cascade of brain regions to become activated in a particular order: auditory cortex, frontal regions, such as BA44 and BA47, and finally the mesolimbic system, culminating in the nucleus accumbens. And he found the cerebellum and basal ganglia were active throughout the session. He argues music mimics some of the features of language and conveys some of the same emotions. The brain regions pulse with the beat and predict the next one. As the music is heard it is modeled and generates dopamine rewards for matching each beat and noting creative jokes in the rhythm.

How the Mind Works

our minds operate. Having set
the scene by exposing the complexity of the deceptively
simple challenges we face and introduced the strategy
for investigating how it works, he shows how a cognitive niche is Tooby & DeVore's theory that reflects a flexible competitive strategy, described by Steven Pinker, which leverages the power and flexibility of intelligence to defeat the capabilities of genetically evolved specialists focused on specific niches.

of human ethics, emotions are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism.
and reproduction. He concludes that: sight, action, common
sense, violence and morality provides rules for identifying right from wrong. It develops in stages with children using play to work out rules of appropriate behavior. Kohlberg's 1950s experiments using children led him to conclude moral judgement is a cognitive process that develops in three stages. Sapolsky raises issues with the framework: Its a model, It does not apply to other cultures, Intuition & emotion are as significant as cognition, Moral reasoning doesn't predict moral actions; and notes the capacity of the frontal cortex to regulate emotions and behavior is far more predictive. The marshmallow test, performed on three to six year olds, actually predicted their subsequent SAT scores at high school, social success and lack of aggression, and forty years on more PFC activation during a frontal task and a lower BMI! Jonathan Haidt argues people's moral decisions are rationalizations rather than using reasoning. ;

- Events are only partially ordered. The present is

- The difference between past and future is not foundational.
It occurs because of state that through our blurring appears

- Time passes at different speeds dependent on where we are and how fast we travel
- Time's rhythms are due to

- The ignorance determines the existence of thermal time

- Directionality of time is real

evolution, not culture is how we do and think about things, transmitted by non-genetic means as defined by Frans de Waal. CAS theory views cultures as operating via memetic schemata evolved by memetic operators to support a cultural superorganism. Evolutionary psychology asserts that human culture reflects adaptations generated while hunting and gathering. Dehaene views culture as essentially human, shaped by exaptations and reading, transmitted with support of the neuronal workspace and stabilized by neuronal recycling. Damasio notes prokaryotes and social insects have developed cultural social behaviors. Sapolsky argues that parents must show children how to transform their genetically derived capabilities into a culturally effective toolset. He is interested in the broad differences across cultures of: Life expectancy, GDP, Death in childbirth, Violence, Chronic bullying, Gender equality, Happiness, Response to cheating, Individualist or collectivist, Enforcing honor, Approach to hierarchy; illustrating how different a person's life will be depending on the culture where they are raised. Culture: - Is deployed during pregnancy & childhood, with parental mediation. Nutrients, immune messages and hormones all affect the prenatal brain. Hormones: Testosterone with anti-Mullerian hormone masculinizes the brain by entering target cells and after conversion to estrogen binding to intracellular estrogen receptors; have organizational effects producing lifelong changes. Parenting style typically produces adults who adopt the same approach. And mothering style can alter gene regulation in the fetus in ways that transfer epigenetically to future generations! PMS symptoms vary by culture.

- Can provide varying levels of support for innovation. Damasio suggests culture is influenced by feelings:
- As motives for intellectual creation: prompting
detection and diagnosis of homeostatic
deficiencies, identifying
desirable states worthy of creative effort.
- As monitors of the success and failure of cultural
instruments and practices
- As participants in the negotiation of adjustments

They also signal [social] emotional state to other people. And they have implicit censorious power with pictures of eyes encouraging people within their view to act more honorably. Eyes are poor scanners and use a saccade to present detail slowly to the fovea. The eye's optical structures and retina are supported by RPE.

commodity, its dependence on increasing: military power, returns for
the control points in the value delivery system(VDS), availability of land
and labor to work it including slaves.
He explains how cotton offered the opportunity for
industrialization further amplifying the productive capacity of
the VDS and the power of the control points. This VDS was quickly
copied. The increased capacity of the industrialized
cotton complex adaptive system (CAS) required more labor to
operate the machines. Beckert describes the innovative introduction of wages
and the ways found to
mobilize industrial labor.
Beckert describes the characteristics of the industrial cotton
CAS which made it flexible enough to become globally interconnected.
Slavery made the production system so cost effective that all
prior structures collapsed as they interconnected. So when
the US civil war
blocked access to the major production nodes in the
American Deep South the CAS began adapting.
Beckert describes the global
reconstruction that occurred and the resulting destruction of the traditional ways
of life in the global countryside. This colonial expansion
further enriched and empowered the 'western' nation states. Beckert explains
how other countries
responded by copying the colonial strategies and creating
the opportunities for future armed conflict among the original
colonialists and the new upstarts.
Completing the adaptive
shifts, Beckert describes the advocates for industrialization in
the colonized global south and how over time they joined
the global cotton CAS disrupting the early western manufacturing
nodes and creating the current global CAS
dominated by merchants like Wal-Mart
pulling goods through a network of clothing manufacturers,
spinning and weaving factories, and growers competing with each
other on cost.
Following our summary of Beckert's book, RSS comments from the

evolved and it supports our behaviors. As Dawkins
explained in the
Selfish Gene, genes selfishly spread themselves by the
way they build our brains. By making us enjoy: life,
sex, health, friends and children; genes help themselves get
into the next generation. So our goals are about
health, lovers, children and friends. Our mind's
strategies do not have to be selfish.
Pinker sees an internal struggle between alternate modules
played out on a mental chessboard. Other people's behavior

leveraged by the mind.

- Sex
- Finding and maintaining shelter

Rationality is generated by rules. Desires and

Common sense has the power and precision to explain everyday

He suggests intelligence comes from information processing, via
a Turing machine, a machine specified by mathematician Alan Turing which is the blueprint for the electronic programmable computer. It consists of an infinite tape on which symbols can be written. A movable read/write tape head which can move about the tape and write on or read symbols from the tape. A set of rules that tell the head what to do next.

this is the first useful model of intelligence:

In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy. ,

The defending champion
The computational
theory of the mind describes the aggregate ideas of: Alan Turing, Alan Newell, Herbert Simon, Marvin Minsky, Hilary Putnam & Jerry Fodor; that beliefs and desires are information, bound through sense organ triggered associations with neuronal or other symbolic representations that once triggered give rise to other symbols and muscular actions generating behaviors. For Steven Pinker the theory allows behavior to be explained by beliefs and desires and makes the beliefs and desires part of the physical universe. has two famous criticisms:

natural selection.
McCulloch & Pitts developed a mathematical model of a
network of neurons. The network was built from simple
logical models of neurons representing just their input,
transform by adding inputs and thresholding and output
(signalling) properties. Pinker notes that real neurons
are highly complex and not fully characterized. McCulloch
& Pitts neural networks could be modelled in a computer to
perform: logical AND OR and NOT operations and propositions such
as 'if this then' via patterns of activity over sets of network
units.
Pinker notes that this neural computer can be made biomorphic
by:
Pinker explains that connecting each network element to all the
others constructs an auto-associator with five key properties:
- It is reconstructive and content addressable making it
robust
- It degrades gracefully
- It can perform constraint satisfaction in parallel
- It automatically generalizes
- It can learn by example by being fed both inputs and
correct outputs. Such a network structure is a
Perceptron.
But perceptron's can't perform the logical XOR operation.
To allow the XOR a hidden layer of elements must be added which
can independently represent the intermediate result input
elements of the XOR. Such a hidden layer neural network
can still be trained by adding backpropagation is the backward propagation of errors which is used together with an optimization method such as gradient descent to train artificial neural networks. With GPU performance helped by Moore's law it has become an important strategy. It uses the chain rule to iteratively compute gradients for each layer of the network. Backpropagation assumes there is a known correct output (y) for each training input (x) making it a supervised learning method. Backpropagation typically repeats two phases until performance is satisfactory: - Propagation includes:
- Forward propagation of the training pattern's inputs through the network to generate the output activations: hypothesis (Weight,bias).
- The total weighted sum of inputs to unit i in layer l including bias: z i(l) = sum from j=1 to n of Weight ij (l) xj + bias i(l) -> activation a i(l) = f (z i(l)); Final layer activation vector (a) is the output hypothesis vector.
- Backward propagation of the propagation's output activations of each neuron like element (a) through the network using the training pattern target (y) to determine the deltas of all output and hidden nodes. One determination of the error between y and hidden layer element output activation is error = 1/2*(hypothesis (Weight,bias) - y)**2 + weight decay (Weight).
- Input weights are updated by gradient descent:
- Multiplying the weight's output delta and input activation to generate a gradient from the weight.
- Subtracting a percentage (learning rate) of the gradient from the weight.
connections.
Pinker notes that the point of integration between the mind's
rules and representations and the brains neural networks is not
agreed among psychologists. Some following Rumelhart
and Mclelland's connectionism school assert that backpropagating
neural networks do everything. Pinker is in the other camp
which argues that neurons have to be structured into programs
for manipulating symbols. Once this has been done the
symbol manipulation becomes significant for much of human
intelligence.
Pinker argues that our thoughts
have a delicate logical structure that a network of homogeneous
layers of units can't handle. He highlights five aspects
of everyday thought:
- The concept of the individual is significant. It has
a unique history. Two individuals can't be in the same
place at the same
Carlo Rovelli resolves the paradox of time.
Rovelli initially explains that low level physics does not
include time:
- A present that is common throughout the universe does not exist
- Events are only partially ordered. The present is
localized
- The difference between past and future is not foundational.
It occurs because of state that through our blurring appears
particular to us
- Time passes at different speeds dependent on where we are and how fast we travel
- Time's rhythms are due to
the gravitational field
- Our quantized physics shows neither
space nor time, just processes transforming physical
variables.
- Fundamentally there is no time. The basic equations
evolve together with events, not things
Then he
explains how in a physical world without time its perception can
emerge:
- Our familiar time emerges
- Our interaction with the world is partial, blurred,
quantum indeterminate
- The ignorance determines the existence of thermal time
and entropy that quantifies our uncertainty
- Directionality of time is real
but perspectival. The entropy of the world in
relation to us increases with our thermal time. The
growth of entropy distinguishes past from future: resulting in
traces and memories
- Each human is a
unified being because: we reflect the world, we
formed an image of a unified entity by
interacting with our kind, and because of the perspective
of memory
- The variable time: is one
of the variables of the gravitational field.
With our scale we don't
register quantum fluctuations, making space-time
appear determined. At our speed we don't perceive
differences in time of different clocks, so we experience
a single time: universal, uniform, ordered; which is
helpful to our decisions

cross-talk.
- Recursive ideas are hard to represent in a general neural
network. Each kind of recursive structure would imply
a different hard-wired neural network. The recursions
can be easily represented with a recursive transition
network but they must be specially assembled.
- Fuzzy logic and crisp versions of the same category are
present side by side in our minds. This is hard to
represent with a homogeneous neural network. All such
collections lack a single defining feature but overlap in
many features.
With this critique Pinker aims to highlight the power of human
thought which supports our capacity for love is an emotion, which generates a feeling of pleasure at a genetic relative's well-being and pain in their harm. An inseminated human female is genetically a full relative of her partner since she carries his germ-line gametes. From any of their pooled gene's perspective the offspring have a one-in-two chance of including the specific gene. Hence love supports kin selection driven by the selfish actions of genes. Emotions, including love and anger, help drive the interactions between people. Compassionate love also supports the symbiotic partnership of true friends built on fairness and trust. Sapolsky notes the opposite of love is indifference, not hate.

suggests consciousness is a product of culture is how we do and think about things, transmitted by non-genetic means as defined by Frans de Waal. CAS theory views cultures as operating via memetic schemata evolved by memetic operators to support a cultural superorganism. Evolutionary psychology asserts that human culture reflects adaptations generated while hunting and gathering. Dehaene views culture as essentially human, shaped by exaptations and reading, transmitted with support of the neuronal workspace and stabilized by neuronal recycling. Damasio notes prokaryotes and social insects have developed cultural social behaviors. Sapolsky argues that parents must show children how to transform their genetically derived capabilities into a culturally effective toolset. He is interested in the broad differences across cultures of: Life expectancy, GDP, Death in childbirth, Violence, Chronic bullying, Gender equality, Happiness, Response to cheating, Individualist or collectivist, Enforcing honor, Approach to hierarchy; illustrating how different a person's life will be depending on the culture where they are raised. Culture: - Is deployed during pregnancy & childhood, with parental mediation. Nutrients, immune messages and hormones all affect the prenatal brain. Hormones: Testosterone with anti-Mullerian hormone masculinizes the brain by entering target cells and after conversion to estrogen binding to intracellular estrogen receptors; have organizational effects producing lifelong changes. Parenting style typically produces adults who adopt the same approach. And mothering style can alter gene regulation in the fetus in ways that transfer epigenetically to future generations! PMS symptoms vary by culture.
- Is also significantly transmitted to children by their peers during play. So parents try to control their children's peer group.
- Is transmitted to children by their neighborhoods, tribes, nations etc.
- Influences the parenting style that is considered appropriate.
- Can transform dominance into honor. There are ecological correlates of adopting honor cultures. Parents in honor cultures are typically authoritarian.
- Is strongly adapted across a meta-ethnic frontier according to Turchin.
- Across Europe was shaped by the Carolingian empire.
- Can provide varying levels of support for innovation. Damasio suggests culture is influenced by feelings:
- As motives for intellectual creation: prompting
detection and diagnosis of homeostatic
deficiencies, identifying
desirable states worthy of creative effort.
- As monitors of the success and failure of cultural
instruments and practices
- As participants in the negotiation of adjustments
required by the cultural process over time

fastest, or strongest agent one level down. Pinker
says it corresponds to our having one body to act
with. Coherence demands a unitary executive.
- Sentience
- subjective experience, phenomenal awareness, Raw feelings are subjective models: sad, glad, mad, scared, surprised, and compassionate; of the organism and its proximate environment, including ratings of situations signalled by broadly distributed chemicals and neural circuits. These feelings become highly salient inputs, evolutionarily associated, to higher level emotions encoded in neural circuits: amygdala, and insula. Deacon shows James' conception of feeling can build sentience. Damasio, similarly, asserts feelings reveal to the conscious mind the subjective status of life: good, bad, in between; within a higher organism. They especially indicate the affective situation within the old interior world of the viscera located in the abdomen, thorax and thick of the skin - so smiling makes one feel happy; but augmented with the reports from the situation of the new interior world of voluntary muscles. Repeated experiences build intermediate narratives, in the mind, which reduce the salience. Damasio concludes feelings relate closely and consistently with homeostasis, acting as its mental deputies once organisms developed 'nervous systems' about 600 million years ago, and building on the precursor regulatory devices supplied by evolution to social insects and prokaryotes and leveraging analogous dynamic constraints. Damasio suggests feelings contribute to the development of culture:
- As motives for intellectual creation: prompting detection and diagnosis of homeostatic deficiencies, identifying desirable states worthy of creative effort.
- As monitors of the success and failure of cultural instruments and practices
- As participants in the negotiation of adjustments required by the cultural process over time
.
Pinker accepts the experience is self evident but finds no
link between the findings of neuroscience and
psychology and sentience.
Combinatorial
explosion of conjuctions
The visual computation is divided into an unconscious parallel
stage and a conscious serial stage because conjunctions are
combinatorial. Sprinkling combinatorial detectors at every
location in the visual field would be impractical. Having
the conscious processor focused at one location implies that
features at other locations should float around. Anne
Treisman, by Anne Treisman and Garry Gelade, hypothesizes that perceiving a stimulus is initially a parallel automatic registration of features. Later, objects are identified in a serial stage of processing. Treisman showed that people distracted while looking at colored letter shapes can report the set of letters and the colors but fail to list the correct combinations. found that is exactly what happens.

we can find they assembled incorrectly. Memory in the brain includes functionally different types: Declarative, or explicit, (episodic and semantic), Implicit, Procedural, Spatial, Temporal, Verbal; Hebb suggested that glutamate receptive neurons learn by (NMDA channel based) synaptic strengthening: short term memory. This was shown to happen for explicit memory formation in the hippocampus. This strengthening is sustained by subsequent LTP. The non-real-time learning and planning processes operate through consciousness using the working memory structures, and then via sleep, the salient ones are consolidated while the rest are destroyed and garbage collected. retrieval is also
practically constructed with caches for recent and most used
details.

physical process of forward
causation to iteratively improve an initial autogen generated
by the laws of physics and chemistry. The resulting adaptive in evolutionary biology is a trait that increased the number of surviving offspring in an organism's ancestral lineage. Holland argues: complex adaptive systems (CAS) adapt due to the influence of schematic strings on agents. Evolution indicates fitness when an organism survives and reproduces. For his genetic algorithm, Holland separated the adaptive process into credit assignment and rule discovery. He assigned a strength to each of the rules (alternate hypothesis) used by his artificial agents, by credit assignment - each accepted message being paid for by the recipient, increasing the sender agent's rule's strength (implicit modeling) and reducing the recipient's. When an agent achieved an explicit goal they obtained a final reward. Rule discovery used the genetic algorithm to select strong rule schemas from a pair of agents to be included in the next generation, with crossing over and mutation applied, and the resulting schematic strategies used to replace weaker schemas. The crossing over genetic operator is unlikely to break up a short schematic sequence that provides a building block retained because of its 'fitness'; In Deacon's conception of evolution, an adaptation is the realization of a set of constraints on candidate mechanisms, and so long as these constraints are maintained, other features are arbitrary. complexity

by the compromises inherent in the process used by natural

Hinton & Nowlan demonstrated how the Baldwin effect suggests learning can guide evolution. While some aspects of the organism are setup directly by genes others are left to be set through learning. Trial and error is used to tune the learned settings. Learning can allow a configuration that natural selection is highly unlikely to generate and that is tuned to the proximate environment, to be found by iterative testing. Natural selection can retain the schematic structures that specify the learning infrastructure and the most successful aspects set directly evolving towards a desired outcome. The result looks Lamarckian.

of bits of culture is how we do and think about things, transmitted by non-genetic means as defined by Frans de Waal. CAS theory views cultures as operating via memetic schemata evolved by memetic operators to support a cultural superorganism. Evolutionary psychology asserts that human culture reflects adaptations generated while hunting and gathering. Dehaene views culture as essentially human, shaped by exaptations and reading, transmitted with support of the neuronal workspace and stabilized by neuronal recycling. Damasio notes prokaryotes and social insects have developed cultural social behaviors. Sapolsky argues that parents must show children how to transform their genetically derived capabilities into a culturally effective toolset. He is interested in the broad differences across cultures of: Life expectancy, GDP, Death in childbirth, Violence, Chronic bullying, Gender equality, Happiness, Response to cheating, Individualist or collectivist, Enforcing honor, Approach to hierarchy; illustrating how different a person's life will be depending on the culture where they are raised. Culture: - Is deployed during pregnancy & childhood, with parental mediation. Nutrients, immune messages and hormones all affect the prenatal brain. Hormones: Testosterone with anti-Mullerian hormone masculinizes the brain by entering target cells and after conversion to estrogen binding to intracellular estrogen receptors; have organizational effects producing lifelong changes. Parenting style typically produces adults who adopt the same approach. And mothering style can alter gene regulation in the fetus in ways that transfer epigenetically to future generations! PMS symptoms vary by culture.
- Is also significantly transmitted to children by their peers during play. So parents try to control their children's peer group.
- Is transmitted to children by their neighborhoods, tribes, nations etc.
- Influences the parenting style that is considered appropriate.
- Can transform dominance into honor. There are ecological correlates of adopting honor cultures. Parents in honor cultures are typically authoritarian.
- Is strongly adapted across a meta-ethnic frontier according to Turchin.
- Across Europe was shaped by the Carolingian empire.
- Can provide varying levels of support for innovation. Damasio suggests culture is influenced by feelings:
- As motives for intellectual creation: prompting
detection and diagnosis of homeostatic
deficiencies, identifying
desirable states worthy of creative effort.
- As monitors of the success and failure of cultural
instruments and practices
- As participants in the negotiation of adjustments
required by the cultural process over time
- Produces consciousness according to Dennet.

Pinker views autostereograms are flat pictures that generate a three dimensional illusion within the human visual system. They operate directly through our eyes without support from apparatus. Autostereograms: - Include: Wallpaper, Random-dot, Magic eye; stereograms,
- Depend on four tricks used by natural selection to rapidly resolve a retinal sensor report into a competitively useful representation. The tricks include:
- Leverage the resolution of three dimensional objects projections onto the retina, by building a picture which overlays onto the equivalent 3 dimensional projections. Natural selection leveraged properties of: Surfaces being evenly colored and textured so a gradual change in the markings of the surface is caused by lighting and perspective, Parallel symmetrical right-angled figures appearing to similarly taper are allocated to effects of perspective, Objects have regular compact silhouettes that can be used to predict which ones are nearer.
- Use of the field of overlap from two separate forward facing eyes to rapidly perform the trigonometry operation to obtain stereo depth information about objects in view. This operation of vision is assisted by each eye's lens focusing to maximize fine detail. And each eye is pointed at the same logical spot in the visual world using a control circuit that attempts to minimize double images. These two mechanisms are integrated causing difficulties for stereogram designers.
- A pattern of repeating shapes can lure the eyes into fixating on separate components. When this results in the patterns falling at the same points in both retinas the brain recognizes that it is not seeing double and accepts the alignment driving the objects into three dimensional representations.
- The brain solves the correspondence problem by filtering, assuming that the viewed configuration is typical of those natural selection has experienced on Earth. The resulting cyclopean eye allows the detection of camouflaged prey, unless they have evolved in response by flattening their bodies. The matcher only considers valid matches:
- A valid match must pair up identical points in the two eyes.
- A point in one eye should be matched with no more than one point in the other eye.
- Matter is assumed to be cohesive and smooth. Boundaries take up a small percentage of the view.
- Unconscious constraint matching can apply at the depth the eyes have settled upon using a large array of neural processors. The processors:
- Activate when they get the same input from both eyes.
- Signal nearby processors of their state. Nearby processors registering similar depths excite each other.
- Inhibit other processors for different matches lying along the same line of sight.
- Images may contain parts that are only visible from one eye. There are neurons that report such occlusions as being from an edge in the visual space.

They also signal [social] emotional state to other people. And they have implicit censorious power with pictures of eyes encouraging people within their view to act more honorably. Eyes are poor scanners and use a saccade to present detail slowly to the fovea. The eye's optical structures and retina are supported by RPE. Eyes do not connect to the brain through the brain stem and so still operate in locked-in syndrome. Evo-devo shows eyes have deep homology. High pressure within the eye can result in glaucoma. Genetic inheritance can result in retinoblastoma. Age is associated with AMD.
- Projection of double images as depth indicators
- Correspondence in human vision asks how the marks on the retina of one eye are matched up rapidly with the marks in the other eye's retina. The stereo disparity of a pair of marks is difficult to calculate until you pick the marks to compare. But there are sometimes thousands of candidates, and the brain does not know how far away the marks are. With many candidates for pairing a combinatorial explosion is probable.

processing is the ability to see shapes in stereo that neither eye's visual data can represent in mono.
Stereo vision develops in young children. If input is
withheld from one eye the development is a phase during the operation of a CAS agent. It allows for schematic strategies to be iteratively blended with environmental signals to solve the logistical issues of migrating newly built and transformed sub-agents. That is needed to achieve the adult configuration of the agent and optimize it for the proximate environment. Smiley includes examples of the developmental phase agents required in an emergent CAS. In situations where parents invest in the growth and memetic learning of their offspring the schematic grab bag can support optimizations to develop models, structures and actions to construct an adept adult. In humans, adolescence leverages neural plasticity, elder sibling advice and adult coaching to help prepare the deploying neuronal network and body to successfully compete.

This ground breaking insight induced researchers to explore the temporal cortex and eventually led to Tanaka's identification of neuronal alphabets.
showed that is because all the neurons, specialized eukaryotic cells include channels which control flows of sodium and potassium ions across the massively extended cell membrane supporting an electro-chemical wave which is then converted into an outgoing chemical signal transmission from synapses which target nearby neuron or muscle cell receptors. Neurons are supported by glial cells. Neurons include a: - Receptive element - dendrites
- Transmitting element - axon and synaptic terminals. The axon may be myelinated, focusing the signals through synaptic transmission, or unmyelinated - where crosstalk is leveraged.
- Highly variable DNA schema using transposons.

input layer of the cortex includes the paleocortex a thin sheet of cells that mostly process smell, archicortex and the neocortex. The cerebral cortex is a pair of large folded sheets of brain tissue, one on either side of the top of the head connected by the corpus callosum. It includes the occipital, parietal, temporal and frontal lobes. .
Input from the eye adds to the neurons initial bias.
Internal patterns generated by the eyes will do the
tuning. After birth the neurons of the input layer of the
cortex sum data from both eyes as one. At four months each
neuron decides on a favorite eye. The developmental period
is to accommodate the expansion of the skull which moves the
eyes. Once the expansion finishes the development period
completes. Prey animals can't risk the developmental
period of childhood. Their eyes are set by birth.
Pinker notes that the developmental adjustments of stereo vision
processing are part of an assembly schedule with environmental
tuning being circumscribed intake by a structured system rather
than learning.
People suffering from forms of stereoblindness is loss of stereo depth perception. It is a broad term that includes: - Loss of cyclopean eye (2% of the population)
- Poor stereo vision (4%)
- Selective vision deficits - where any of three neuron pools for detecting differences in the position of spots from the two eyes fail - (1) at the point of focus
- Loss of stereo depth behind the point of fixation - pairs of spots (2) flanking the nose for far objects
- Loss of sterio depth infront of the point of fixation - pairs of spots (3) approaching the temples for near objects

dimensional projection. The most probable state of the
world can be deduced from the evidence in the retina with Beyes theorem specifies a conditional probability P(A|B) the posterior belief = (P(B|A) the likelyhood * P(A) our prior belief) /P(B). This says our belief in hypothesis A is updated in light of new evidence B. The power of Bayes rule is that often P(A|B) may be difficult to compute directly but can be calculated from P(B|A). For example: - A is the event a person has cancer.
- B is the event a person smokes.
- If 10% of people who enter a clinic have cancer then P(A) = 0.1; Assumed accurate Baysian prior.
- P(B) is the percentage of people who smoke = 0.5; Assumed accurate prior.
- P(B|A) = 0.8 is the proportion of smokers among those diagnosed with cancer at the clinic from the clinics records.
- P(A|B) = (0.8 * 0.1)/0.5 = 0.16. With evidence that a person is a smoker we revise our estimate of P(A) from 0.1 to a posterior probability of 0.16.

with probabilities about projection (likelihoods) and some

- Reflectance - provides predictions about surfaces (color,
lightness). The visual system supports processing of visual data into what and how. To do this it has two distinct paths: The ventral path and the dorsal path.

specialist factors out levels of illumination. Land's
Retinex theory developed by Edwin Land aims to effectively describe how reflectance of the viewed scene is processed by the human visual system. It assumes: Earth's illumination includes a large mix of wavelengths; Gradual changes in brightness & color across the visual field are produced by illumination, while abrupt transitions indicate boundaries and earth's surface is a big flat plane. But the mind has a shape analyzer that bends perceived surfaces and surfaces are often slanted from the viewer which compromises the predictions of the theory.
effectively removes lighting gradients similarly to the
brain. But the mind also applies 3-D shaping to the
object. And the mind accounts for the effect of slant
on the reflectance.
- Slanting - assumes: Surface lighting is uniform, Surfaces
are matte.
Adelson showed how costs of modeling can be used to optimize the
contributions of the different analyzers. Pinker concludes
that supervision provides the mind with an effective way to
arbitrate the specialized modeling performed by low level
analyzers. And such optimization may generate equally
expensive alternatives as in the Necker cube which we see as
flipping from one perspective to another.

signals, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy. of: Stereo, Lighting, Shading, and
Shaping; to a cellular mosaic with any element potentially
representing part of a surface or an edge. Neighboring
neurons respond to neighboring parts of the visual field.
The mosaic is a visual map: LGN is lateral geniculate nucleus. It is a contradiction: - It looks like a relay and nothing more. Both anatomically and physiologically it seems to be a relay. The principal cells receive inputs from the retina and send outputs, seen radiating out to the visual cortex, to the first visual area (V1) of the neocortex (in primates - in cats they go to a number of visual areas). These axons have very few collateral branches to other principal cells or to other parts of the LGN. There is a direct map from retinal area to primary visual cortex area. But Francis Crick argued in contradiction to this
- It is probably doing something a lot more complicated which we do not yet fully understand! The macaque LGN has six layers. The inputs from two eyes and M & P cells within them are all kept separate within the LGN.
- Two of these layers have large cells (magnocellular). One of them gets its inputs from the right eye, the other from the left eye. There is little interaction between the layers. Their input is mainly from the M cells of the retina. These two layers specialize in detecting movement and flicker.
- Four of the layers are smaller (parvocellular). They receive input from the P cells of the retina. They seem to carry signals relating to color, texture, shape & steropsis.
- The LGN neurons also get input coming back from the first visual area of the cortex. There are many more axons coming back than go to the neocortex from the LGN. However, they tend to synapse onto those parts of the dendrites rather distant from the cell bodies so their effects are probably subdued.
- There are also inputs from the brain stem that modulate the behavior of the thalamus and especially its reticular nucleus. This means that the LGN freely transmits visual information in the awake higher animal but blocks this transmission somewhat when the animal is in slow wave sleep.
- Dehaene identifies the LGN as at the base of a hierarchy of reading neurons signalling local contrasts and oriented bars. The signals reach
- V1 which associates them with oriented bars,
- V2 - letter fragments,
- V4 Letter shapes,
- V8 abstract letters,
- Left occipital temporal sulcus - bigrams,
- Left occipital temporal sulcus - small words, frequent substrings and morphemes.

Frames of reference
There are various reference
frames is a coordinate system (set of axis) centered on a particular aspect of the situation that describes the location of an object. The brain supports many frames of reference including for vision (2009), hearing & movement planning (Jul 2002). Auditory stimuli are initially coded in a head-centered reference frame. The motor system codes actions in reference frames that depend on motor effectors. Eye movements are codes in a reference frame that depends on the difference between current and desired arm position. It is often necessary to transform the location representation of the sensory stimulus into a representation appropriate for the motor act. An eye-centered reference frame depends on the location of the eye in the head. A retinotopic reference frame depends on the retinal location that is activated by a visual stimulus. Double-saccade tasks show how the location of the second visual target is coded relative to current and desired eye position (eye-centered). maintained by the mind:

Pinker explains how Biederman's Geons are an inventory of 24 simple geometric parts, identified by Irv Biederman, including: Cone, Megaphone, Ball, Tube, Cube, Macaroni elbow; each of which comes in fifteen sizes and builds. They can be assembled into objects with eighty-one object relative frame based relations: Above, Beside, End-to-end, End to off-center, Parallel. Geons are used by visual finders to describe 3-D reference frame oriented basic visual objects. These representations reside next to representations of language in the human brain's left hemisphere. combine with an object
based frame of reference to allow a matcher to compare the
visual object with a memorized construction made of
grammatically joined Geons. Pinker notes that language and complex
shape recognizers reside near one another in the
brain.
But psychologists tests indicated that people may not always use
Geons to represent objects. They identified three
possibilities and concluded that all three are used:
- Multiple-view
theory suggests that a seperate memory representation is created for each orientation in which a visual object regularly appears.
- habitually seen views are rapidly identified
and shaped.
- Mental-rotation
theory suggests that people rapidly identify upright objects, but when the objects are rotated people perform a rotation in their minds to bring the object into its upright position to allow shape recognition. - in odd rotational views people perform
mental rotations in their minds.
- Geon theory - is used for some shapes.

These mathematical objects can be values of variables, allowing them to be used in formulas. in space. And
these images affect both intellect and emotions are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism. . But images
are too concrete, and ambiguous, to represent the abstract ideas we use to reason about the
world.
Images affect perception in various ways:

The patterns are surface representations from specific
orientations and implicitly include perspective. When an
object is examined it is typically repositioned multiple times
so that a series of alternate images are recorded. That
makes the associated perspectives conflict which Pinker suggests
explains why it took so long for artists to deal effectively
with perspective. Thinking about images depends on the visual pathways supports processing of visual data into what and how. To do this it has two distinct paths: The ventral path and the dorsal path. .
Patients suffering from visual neglect occurs when brain injuries or strokes damage the visual pathways of the brain. Right parietal lobe damage typically leads to neglect of the left side of the visual field, where the left side of the cyclopean view is ignored. can't
image a scene in the damaged area. PET is positron emission tomography which uses a radioactive tracer (Nuclear medicine) to look for disease processes. The tracer is intravenously deployed through the blood stream where it collects in organs and tissues. A whole body scanner is then used to count the indirect gamma ray emissions and a computer builds a 3 dimensional representation. If the tracer is an analog of glucose such as fluorodeoxyglucose the concentrations of tracer imaged will indicate tissue metabolic activity (glucose uptake). This can be used to explore for early signs of cancer (unusually active cells) metastasis. scans of mental imaging

Surgically removing part of the visual chain shrank the width of
mental images.
Visual images must be able to be distinguished from mental
images to limit confusion about reality and memory. This
may be why mental images are sensed as faint equivalents of the
original visual images.
Pinker illustrates how mental images are represented:
- Mainly images appear to be fragments of observed scenes
and are represented as a concrete pictorial matrix rather
than a sentence of a grammar. But Pinker notes
- Each image is represented in a propositional
superstructure which allows the mental images to be
found quickly. This superstructure may be 'chunked'
with practice. Pinker notes that
- Images are geometric without any associated meaning but
they can be compared and reasoned with. And they may
be manipulated by well-defined operations: Rotation,
zooming, shrinking, panning, scanning, tracing, coloring;
that can be strung together. Rotation is incremental
and time consuming.

Evolutionarily
significant features: cat claws, bees' stingers; are
registered in a conceptual database via an explicit
statement. Otherwise the image must be reviewed and
the shape analyzers applied. Pinker argues that
discovering previously missed features is a key value of
recalling mental images.
Good Ideas
Pinker continues to dissect the mind, reviewing how of the cerebral cortex is at the front of the brain. It includes the: prefrontal cortex, motor cortex. Sapolsky asserts it makes you do the harder thing when it's the right thing to do. The frontal cortex supports working memory to sustain focus on a task. It also coordinates the strategic actions necessary to achieve success. It provides impulse control, regulation of emotion, and willpower. The prefrontal cortex maintains focus by deprioritizing currently irrelevant streams of information. The frontal cortex tracks rules. Over a lifetime, that builds into a costly activity. Once it tires, responses become less prosocial. But practice shifts operation of tasks to the cerebellum. The frontal cortex signals the tegmentum and accumbens with the conclusions of its expectancy/discrepancy calculations. The frontal lobe provides executive function, considering bits of information, assessing patterns and then prioritizing the strategies. The frontal lobe is the most recent part of the brain to evolve and involves a disproportionate percentage of primate-unique genes in its development and operation. It does not complete development until the mid-20s. It includes spindle neurons. It is easily damaged. Sapolsky (Nauta) notes that its ventromedial prefrontal cortex is a quasi-member of the limbic system. humans' reason to
make sense of the world. He argues that to explain human
reasoning he must resolve Wallace's paradox is Alfred Russel Wallace's conclusion that the mind is overdesigned for the needs of evolving humans and cannot be explained by natural selection. Instead Wallace proposed spiritual powers guided human destiny, which horrified Darwin. .
He suggests that foraging tribe's challenges are similar to our

Hunter-gatherers is a lifestyle organized around a band of relatives, evolved in humans focused on capturing the cognitive niche in the African savanna. It is of great significance in shaping our minds: behaviors, emotions, creativity, intelligence; and developing survival strategies including use of fire and language, according to evolutionary psychologists. It was practiced by all humans, for most of Homo sapiens existence, until the emergence of farming, and still is by some isolated bands: Ju/'hoansi, New Guinea: Gebusi, Mae Enga; & Borneo head hunters, Maasai & Zulu warriors from Africa, Amazonians: Waorani, Jivaro; Brazilian and Venezuelan Yanomamo. Since the band moves on when it has depleted the resources in an area of land, the soil remains vibrant, but the large animals were typically placed in a position of stress from which they did not recover.

them to use abstractions and foresight (PFC) is - The front part of the frontal lobe of the cerebral cortex. It evolved most recently. During adolescence when the PFC is still deploying, older brain agents provide equivalent strategies: ventral striatum. The PFC has been implicated in planning, working memory: dorsolateral; decision making: Orbitofrontal cortex; and social behavior. It regulates feelings. Different PFC circuits track internal reward driven strategies and externally signalled advice. The PFC chooses between conflicting options, letting go or restraint, especially between cognition and emotions. It imposes an overarching strategy for managing working memory. It is essential for thinking about multiple items with different labels. It includes neurons that are interested in particular sub-categories: Dog, Cat. Once it has made a decision it signals the rest of the frontal lobe just behind it. Glucocorticoids decrease excitability of the PFC.

properties of the situation have been placed in a historic
classification, other properties of the local situation can be
predicted from the understanding of the classification.

its costs are prohibitive for hunter-gatherers is a lifestyle organized around a band of relatives, evolved in humans focused on capturing the cognitive niche in the African savanna. It is of great significance in shaping our minds: behaviors, emotions, creativity, intelligence; and developing survival strategies including use of fire and language, according to evolutionary psychologists. It was practiced by all humans, for most of Homo sapiens existence, until the emergence of farming, and still is by some isolated bands: Ju/'hoansi, New Guinea: Gebusi, Mae Enga; & Borneo head hunters, Maasai & Zulu warriors from Africa, Amazonians: Waorani, Jivaro; Brazilian and Venezuelan Yanomamo. Since the band moves on when it has depleted the resources in an area of land, the soil remains vibrant, but the large animals were typically placed in a position of stress from which they did not recover. .
Eleanor Rosch noted that most of our prescientific
classifications are 'basic-level is psychologist Eleanor Rosch's term for evolved mental categories. These categories reflect the way the world works. They are the first words a child learns: Rabbit, Car; categories that in consequence are useful, since they have high predictive value.

Pinker notes there are two types of classification:
- Stereotypes with fuzzy boundaries and family like
resemblances. These are useful because they predict
from similarity.
- Definitions with in-or-out boundaries. These allow
discovery of laws of the structural clusters. They
fall out of the intuitive theories that guess at the
operating mechanisms of the world. These are useful
because of their deductive power.
Items can be placed in both types of class. Science helps
shift items from category 1 to category 2 by identifying the
underlying laws.
The intuitive laws are used by the mind to make predictions and
inferences about unseen members of the set.

evolutionary
theory shows why some classes can be in-or-out like birds,
while others utilizing history are fuzzy like fish. Fish
are a broad class that really includes: Amphibia, Reptiles and
humans. But pre-scientific classification aims to place
similar looking fish into one class which will contain stumps
where the classification has excluded these other related
classes. Fish is fuzzy.
Pinker argues that in-and-out classifications make sense because
the systems of
rules create idealizations that abstract away the complicating
aspects of reality (PFC) is - The front part of the frontal lobe of the cerebral cortex. It evolved most recently. During adolescence when the PFC is still deploying, older brain agents provide equivalent strategies: ventral striatum. The PFC has been implicated in planning, working memory: dorsolateral; decision making: Orbitofrontal cortex; and social behavior. It regulates feelings. Different PFC circuits track internal reward driven strategies and externally signalled advice. The PFC chooses between conflicting options, letting go or restraint, especially between cognition and emotions. It imposes an overarching strategy for managing working memory. It is essential for thinking about multiple items with different labels. It includes neurons that are interested in particular sub-categories: Dog, Cat. Once it has made a decision it signals the rest of the frontal lobe just behind it. Glucocorticoids decrease excitability of the PFC.

Pinker notes could be rational but immoral provides rules for identifying right from wrong. It develops in stages with children using play to work out rules of appropriate behavior. Kohlberg's 1950s experiments using children led him to conclude moral judgement is a cognitive process that develops in three stages. Sapolsky raises issues with the framework: Its a model, It does not apply to other cultures, Intuition & emotion are as significant as cognition, Moral reasoning doesn't predict moral actions; and notes the capacity of the frontal cortex to regulate emotions and behavior is far more predictive. The marshmallow test, performed on three to six year olds, actually predicted their subsequent SAT scores at high school, social success and lack of aggression, and forty years on more PFC activation during a frontal task and a lower BMI! Jonathan Haidt argues people's moral decisions are rationalizations rather than using reasoning. . He explains
that our brains include a switch has been studied by psychologist Paul Rozin. He showed that once the switch turns on key actions are constrained by fundamental moral senses. These constraints are implemented by the medial frontal lobes. When the switch is disabled utilitarian logic, supported in the dorsolateral frontal lobes will be used to make decisions. The conflict between the two areas is registered in the anterior cingulate cortex.

folk psychology mental modules:
- Feelings are subjective models: sad, glad, mad, scared, surprised, and compassionate; of the organism and its proximate environment, including ratings of situations signalled by broadly distributed chemicals and neural circuits. These feelings become highly salient inputs, evolutionarily associated, to higher level emotions encoded in neural circuits: amygdala, and insula. Deacon shows James' conception of feeling can build sentience. Damasio, similarly, asserts feelings reveal to the conscious mind the subjective status of life: good, bad, in between; within a higher organism. They especially indicate the affective situation within the old interior world of the viscera located in the abdomen, thorax and thick of the skin - so smiling makes one feel happy; but augmented with the reports from the situation of the new interior world of voluntary muscles. Repeated experiences build intermediate narratives, in the mind, which reduce the salience. Damasio concludes feelings relate closely and consistently with homeostasis, acting as its mental deputies once organisms developed 'nervous systems' about 600 million years ago, and building on the precursor regulatory devices supplied by evolution to social insects and prokaryotes and leveraging analogous dynamic constraints. Damasio suggests feelings contribute to the development of culture:
- As motives for intellectual creation: prompting detection and diagnosis of homeostatic deficiencies, identifying desirable states worthy of creative effort.
- As monitors of the success and failure of cultural instruments and practices
- As participants in the negotiation of adjustments required by the cultural process over time

danger, contamination is a universal human emotion. Pinker notes it has its own facial expression and is codified in food taboos. The mind must be associated with the proximate environment and parents minimize the risk for their omnivorous children by teaching them what foods to eat and what to avoid. The children's minds are initially receptive to trying all foods but their brains subsequently lock in on the foods they have experienced. These parental choices are affected by schematic influence on what has been beneficial. Adolescent's brain developments undermine these constraints enabling intergroup transfers. Disgust is modulated by the insula cortex which projects signals to the amygdala. Adult humans merge moral and physical disgust enabling metaphorical out grouping. ,
status, dominance, fairness, love is an emotion, which generates a feeling of pleasure at a genetic relative's well-being and pain in their harm. An inseminated human female is genetically a full relative of her partner since she carries his germ-line gametes. From any of their pooled gene's perspective the offspring have a one-in-two chance of including the specific gene. Hence love supports kin selection driven by the selfish actions of genes. Emotions, including love and anger, help drive the interactions between people. Compassionate love also supports the symbiotic partnership of true friends built on fairness and trust. Sapolsky notes the opposite of love is indifference, not hate. The amygdala's projection into the locus ceruleus drives autonomic intensity. , friendship, sexuality is a passionate emotion reflecting the risky agreement to commit resources to the long term activity of raising children. The genes ensure that once a person has chosen, the critical-thinking pathways shut down. That is especially necessary for women to ignore the uncertainty - they become more passionately in love than men. For both partners initial separations remove the oxytocin (and vasopressin in men) and dopamine rewards from touching & hugging, generating withdrawal driving the couple closer. The same circuits, driven again by oxytocin signalling, encourage a mother to fall in love with her newborn baby. , children, relatives & the

understanding of gravity or inertia, according to Galilei-Newton, requires that a body removed sufficiently far from other bodies continues in a state of rest or of uniform motion in a straight line. This law of inertia also constrains which systems of co-ordinates fit with mechanics, aligning the model with experimental results. Einstein postulated that Newton's laws should be covariant when transformed between a fixed and moving reference frame. .
Adults assume forces are acting to explain movement when only
inertia is present. Pinker explains that Newtonian
mechanics is hard to apply effectively being obscured by
the real world's friction.

Babies are upset when faces is a region of the brain which supports advanced mechanisms of shape recognition and implements the early stages of reading. Subliminal priming with words did not depend on the shape of the word. The fusiform gyrus was able to process the abstract identity of a word without caring if it was upper or lower case. While high up in the cortex it can operate below the level of conscious experience. It contributes to social emotions with: - Its face area being more activated by faces with in-group skin color.
- It activating when shown pictures of cars in automobile aficionados.
- It activating when shown pictures of birds in birdwatchers; since it really recognizes examples of items from an individual's emotionally salient categories.

Autistics is a major hereditary mental disorder that starts before age three when it features: a strong preference to be alone, a desire for things to stay the same, and areas of creative ability - they see the ordinary as beautiful and have special talents for: poetry, foreign languages, music, art, and calculations. They generate less but more original ideas. It occurs as a spectrum of symptoms, from mild to severe, across the population of sufferers (ASD). Before age two the circumference of an autistic child's head is larger than typical and regions: amygdala, frontal lobe; develop prematurely, altering activity in other regions. Autism highlights aspects of the brain's specialized regions and processes for interacting with other people. Autistic's interests are restricted. They struggle with social interactions & verbal and nonverbal communications. Autistics do not attribute minds to other people: attributing mental states to others allows us to predict their behavior; a critical skill for social learning and interaction. While their visual area MT detects motion, the superior temporal sulcus does not respond to biological motion in autistics, undermining the understanding of intention. And they gaze at mouths rather than eyes when looking at faces. The default mode network is disrupted. Autistic adolescents have unusually large numbers of synapses, because of a failure of synaptic pruning. Autistics almost never pretend. They can't explain the difference between an instance of an object and a memory of it. Mild autism still maintains some pressure to conform socially and often results in depression and anxiety. Autism occurs in every country and social class. It lasts a lifetime. It has genetic and neurological causes. Identical twins are 90% likely to both have autism if one of them does. With 50% of genes active in the brain, mutations are likely to impact the development and operation of the brain. The genes: SHANK3, CDH10; are involved but account for a very small percentage of the risk. Facial gaze studies indicate a high genetic influence and an opportunity to identify more genes associated with autism (Jul 2017). Copy number variations: an extra copy of a segment of 25 genes of chromosome 7 increases the risk of ASD, while deletion of the segment causes Williams syndrome; and de novo mutations which drive up the number of autism cases as paternal age has increased in the US. ASD is associated with a reduced fusiform face area response. Tests [in development] for autism include: SynapDx's blood test. do not model

Pinker shows that natural selection is able to capture value in
folk varieties of logic,
mathematics and probability.
So there are mental
modules to support these folk capabilities.
Modified trivium -
logic
Humans are poor at applying logic abstractly to general
problems. Pinker argues this is because our understanding
of the world is locked within our representations of folk knowledge,
language based logic is ambiguous, and logical inferences often
generate a near infinite set of useless options. But
Cosmides identified that people apply logic effectively when
they view an interaction as a contract about an exchange of
benefits and are trying to detect cheating.
Modified
trivium - mathematics
Infants and animals gain from accurately assessing if all the
predators have left the immediate vicinity. Children enjoy
counting, lining up sets and other activities that require a
sense of number. It seems likely that mathematics
developed by unravelling various activities and then formalizing
notions of generic, non-arbitrary operations. Pinker
argues that generalizing and practice both support building
formal mathematical tools out of the folk models.
Modified
trivium - probability
Humans struggle with probability, but Pinker notes that it is
even difficult to accurately define. Tversky and Kahneman
have shown that risk, is an assessment of the likelihood of an independent problem occurring. It can be assigned an accurate probability since it is independent of other variables in the system. As such it is different from uncertainty. is
poorly comprehended. But Gigerenzer and Cosmides &
Tooby found that folk judgments about probability are not
necessarily illogical. Gambling leverages a special
situation developed to isolate events from one another.
Often real world situations bind one event to another in ways
that gambling avoids. So it makes sense to leverage
history to help predict the probable future. And
probability often infers future situations from past
history. But real environments are dynamic and so likely
outcomes may change significantly depending on chance
events.
Pinker also notes that the science of probability, proportions
and percentages are all very modern concepts where the
abstractions get in the way of folk reasoning. Worse,
statisticians note that situations are often incorrectly
assigned to single event probabilities which are un-computable,
rather than relative frequencies that are easily
comprehended. Pinker notes that effective framing will
hugely help people understand the implications of their
situation in: Illness,
Law.
Metaphorical mind
Pinker argues the folk capabilities that natural selection has
gathered into humanity's mental toolbox have been extended due to a
capability to abstractly transform concrete ideas through
metaphor
and analogy. He suggests the abstractions not only
co-opt the words but also the This page discusses the interdependence of perception and

language. From his research he has concluded that a
handful of concepts about places, paths, motions, agency and
causation underlie the literal or figurative meanings of tens of
thousands of words and constructions in all languages
studied. Further he suggests these concepts and relations
appear to be the vocabulary and syntax of mentalese.

Bowerman showed that preschool children spontaneously develop

Rovelli initially explains that low level physics does not
include time:
- A present that is common throughout the universe does not exist
- Events are only partially ordered. The present is
localized
- The difference between past and future is not foundational.
It occurs because of state that through our blurring appears
particular to us
- Time passes at different speeds dependent on where we are and how fast we travel
- Time's rhythms are due to
the gravitational field
- Our quantized physics shows neither
space nor time, just processes transforming physical
variables.
- Fundamentally there is no time. The basic equations
evolve together with events, not things
Then he
explains how in a physical world without time its perception can
emerge:
- Our familiar time emerges
- Our interaction with the world is partial, blurred,
quantum indeterminate
- The ignorance determines the existence of thermal time
and entropy that quantifies our uncertainty
- Directionality of time is real
but perspectival. The entropy of the world in
relation to us increases with our thermal time. The
growth of entropy distinguishes past from future: resulting in
traces and memories
- Each human is a
unified being because: we reflect the world, we
formed an image of a unified entity by
interacting with our kind, and because of the perspective
of memory
- The variable time: is one

- Love is a force, madness, magic war
- The visual field is a container
- Self-esteem is a brittle object
- Time is money
- Life is a game of chance.

Pinker uses the extreme example of running amok is a Malay word describing the homicidal actions occasionally performed by lonely Indochinese men who have suffered a loss of love, money or face. The syndrome occurs across cultures. An amok man responds autonomously and can't be reasoned with. But Steven Pinkers explains it is: - An emotional result of lengthy brooding over failure,
- Carefully planned as a means of deliverance from an unbearable situation
- Cognitive - It is triggered by an idea, rather than some immediate stimulus or tumor
- I am not an important or "big man."
- I possess only my personal sense of dignity
- My life has been reduced to nothing by an intolerable insult which means
- I have nothing to lose except by life, which is nothing, so I trade my life for yours, as your life is favored.
- I will kill many of you which will rehabilitate myself in the eye of the group (amok) of which I am a member even though I might be killed in the process.

illustrate the cognitive is the ability to orchestrate thought and action in accordance with internal goals according to Princeton's Jonathan Cohen. ,
irrational nature and universal applicability of emotions are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism. .

works on all aspects of the brain and body in tandem. He
concludes the assumption
of a compartmented, modular, layered triune brain is Dr. Paul MacLean's popular but discredited 1940s theory of the brain. He proposed a three layer structure: - Reptilian inner brain containing circuits for basic survival; which is interfaced to layer 2 through the hypothalamus and together with the brain stem, spine and projections into the body make up the autonomic nervous system.
- Limbic middle brain containing emotional circuits which signal layer 1 through the hypothalamus.
- Rational outer brain which is uniquely human.

flawed. The amygdala contains > 12 distinct areas: Central, Lateral. It receives simple signals from the lower parts of the brain: pain from the PAG; and abstract complex information from the highest areas: Disgust, heart rate, and suffering from the insula cortex, allowing it to orchestrate emotion. It connects strongly to attention focusing networks. It sends signals to almost every other part of the brain, including to the decision making circuitry of the frontal lobes. It has high levels of D(1) dopamine receptors. During extreme fear the amygdala drives the hippocampus into fear learning. It outputs directly to subcortical reflexive motor pathways when speed is required. Its central nucleus projects to the BNST. It signals the locus ceruleus. It directly signals area 25. The amygdala: - Promotes aggression. Stimulating the amygdala promotes rage. It converts anger into aggression and when impaired it impacts the ability to detect angry facial expressions.
- Participates in disgust
- Perceives fear promoting stimuli, focusing our attention on these. In PTSD sufferers the Amygdala overreacts to mildly fearful stimuli and is slow to calm down and the amygdala expands in size over a period of months. Fear is processed by the lateral nucleus which serves as the input from various senses, and the central nucleus which outputs to the brain stem (central grey - freezing, lateral hypothalamus - blood pressure, activates paraventricular hypothalamus => crf -> hormone adjustments).
- Has lots of receptors for and is highly sensitive to glucocorticoids. Stress inhibits the GABA interneurons in the basolateral amygdala (BLA) allowing the excitatory glutamate releasing neurons to excite more.
- Is sensitive to unsettling/uncertain social situations where it promotes anxiety and makes us distracted. It is also interested in uncertain but potentially painful situations. The amygdala contributes to social and emotional decision making where the BLA supports rejecting an unacceptable offer, as allowed in the Ultimatum Game, by injecting implicit mistrust and vigilance, generating an anger driven rejection that is used as punishment. The amygdala is very rapidly excited by subliminal signals from the thalamus of outgroup skin color. The amygdala subsequently tips social emotions against outgroups unless restrained by the frontal lobe or influenced by subliminal priming to prioritize inclusion. The fast path from the thalamus rapidly but inaccurately signals its identified a weapon.
- Sees suffering of others as increasingly salient with loving-kindness meditation practice, Goleman & Davidson explain.
- Promotes male, but not female, sexual motivation when it is an uncertain potential pleasure.
- Responds to the longing for uncertain potential pleasures and fear that the reward will not be worth it if it happens. The amygdala turns off during orgasm.
- Uses but is not directly involved in vision.

processing from the frontal
lobes of the cerebral cortex is at the front of the brain. It includes the: prefrontal cortex, motor cortex. Sapolsky asserts it makes you do the harder thing when it's the right thing to do. The frontal cortex supports working memory to sustain focus on a task. It also coordinates the strategic actions necessary to achieve success. It provides impulse control, regulation of emotion, and willpower. The prefrontal cortex maintains focus by deprioritizing currently irrelevant streams of information. The frontal cortex tracks rules. Over a lifetime, that builds into a costly activity. Once it tires, responses become less prosocial. But practice shifts operation of tasks to the cerebellum. The frontal cortex signals the tegmentum and accumbens with the conclusions of its expectancy/discrepancy calculations. The frontal lobe provides executive function, considering bits of information, assessing patterns and then prioritizing the strategies. The frontal lobe is the most recent part of the brain to evolve and involves a disproportionate percentage of primate-unique genes in its development and operation. It does not complete development until the mid-20s. It includes spindle neurons. It is easily damaged. Sapolsky (Nauta) notes that its ventromedial prefrontal cortex is a quasi-member of the limbic system. as in the cold decision making integrates situational context, state and signals to prioritize among strategies and respond in a timely manner. It occurs in all animals, including us and our organizations: - Individual human decision making includes conscious and unconscious aspects. Situational context is highly influential: supplying meaning to our general mechanisms, & for robots too. Emotions are important in providing a balanced judgement. The adaptive unconscious interprets percepts quickly supporting 'fast' decision making. Conscious decision making, supported by the: DLPFC, vmPFC and limbic system; can use slower autonomy. The amygdala, during unsettling or uncertain social situations, signals the decision making regions of the frontal lobe, including the orbitofrontal cortex. The BLA supports rejecting unacceptable offers. Moral decisions are influenced by a moral decision switch. Sleeping before making an important decision is useful in obtaining the support of the unconscious in developing a preference. Word framing demonstrates the limitations of our fast intuitive decision making processes. And prior positive associations detected by the hippocampus, can be reactivated with the support of the striatum linking it to the memory of a reward, inducing a bias into our choices. Prior to the development of the PFC, the ventral striatum supports adolescent decision making. Neurons involved in decision making in the association areas of the cortex are active for much longer than neurons participating in the sensory areas of the cortex. This allows them to link perceptions with a provisional action plan. Association neurons can track probabilities connected to a choice. As evidence is accumulated and a threshold is reached a choice is made, making fast thinking highly adaptive. Diseases including: schizophrenia and anorexia; highlight aspects of human decision making.

prioritization is provided by our evolved emotions are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism. which select what

competitive responses to life's many challenges. Pinker
explains that each human emotion mobilizes the mind and body to
meet one of the challenges of living and reproducing in the cognitive niche is Tooby & DeVore's theory that reflects a flexible competitive strategy, described by Steven Pinker, which leverages the power and flexibility of intelligence to defeat the capabilities of genetically evolved specialists focused on specific niches. .
These challenges (and associated emotion) are:
- Impending harm (fear is an emotion which prepares the body for time sensitive action: Blood is sent to the muscles from the gut and skin, Adrenalin is released stimulating: Fuel to be released from the liver, Blood is encouraged to clot, and Face is wide-eyed and fearful. The short-term high priority goal, experienced as a sense of urgency, is to flee, fight or deflect the danger. There are both 'innate' - really high priority learning - which are mediated by the central amygdala and learned fears which are mediated by the BLA which learns to fear a stimulus and then signals the central amygdala. Tara Brach notes we experience fear as a painfully constricted throat, chest and belly, and racing heart. The mind can build stories of the future which include fearful situations making us anxious about current ideas and actions that we associate with the potential future scenario. And it can associate traumatic events from early childhood with our being at fault. Consequent assumptions of our being unworthy can result in shame and fear of losing friendships. The mechanism for human fear was significantly evolved to protect us in the African savanna. This does not align perfectly with our needs in current environments: U.S. Grant was unusually un-afraid of the noise or risk of guns and trusted his horses' judgment, which mostly benefited his agency as a modern soldier.

- Food for thought (disgust is a universal human emotion. Pinker notes it has its own facial expression and is codified in food taboos. The mind must be associated with the proximate environment and parents minimize the risk for their omnivorous children by teaching them what foods to eat and what to avoid. The children's minds are initially receptive to trying all foods but their brains subsequently lock in on the foods they have experienced. These parental choices are affected by schematic influence on what has been beneficial. Adolescent's brain developments undermine these constraints enabling intergroup transfers. Disgust is modulated by the insula cortex which projects signals to the amygdala. Adult humans merge moral and physical disgust enabling metaphorical out grouping.

Today happiness is associated with Epicurean ideas that were rediscovered during the renaissance and promoted by Thomas Jefferson. But natural selection has 'designed' happiness to support hunter-gatherer fitness in the African savanna. It is assessed: Relative to other's situations, Based on small gains or losses relative to one's current situation; and so what makes us [un-]happy and our responses can seem a counter-productive treadmill. For Pleistocene hunter-gatherers in the savanna there were many ways for losses to undermine fitness and so losses still make us very unhappy. Smoking, drinking and excessive eating were not significant and so don't make us unhappy even though they impact longevity. )
- The Sirens' song (self-control is an emotion, the ability to trade current for future use of resources. Hunter-gatherers are likely to benefit from immediate use of resources, since they have little opportunity to store them. Otherwise the resources, including men & women to reproduce with, may be lost, stolen or degrade. Since the intense drive for men to breed with any available woman can lead to costly disputes and lack of focus on strategic activities, self-control is promoted by parents and other powerful group leaders. But the frontal cortex can promote willpower to increase self-control. Genes also allocate more resources early in the life-cycle to avoid compounding failure to leverage resources to reproduce, with agent accidents and deaths. )
- I and Thou (anger is an emotion which protects a person who has been cheated by a supposed friend. When the exploitation of the altruism is discovered, Steven Pinker explains, the result is a drive for moralistic aggression to hurt the cheater. Anger is mostly experienced as a rapid wave that then quickly dissipates. When it is repressed, for example by a strong moral sense (superego), it can sustain, inducing long term stress.
, gratitude is an emotion that sets the strength of the desire to reciprocate a favor based on the costs and benefits of the earlier gift. When a favor helps a lot and is costly to the giver we are very grateful. , love is an emotion, which generates a feeling of pleasure at a genetic relative's well-being and pain in their harm. An inseminated human female is genetically a full relative of her partner since she carries his germ-line gametes. From any of their pooled gene's perspective the offspring have a one-in-two chance of including the specific gene. Hence love supports kin selection driven by the selfish actions of genes. Emotions, including love and anger, help drive the interactions between people. Compassionate love also supports the symbiotic partnership of true friends built on fairness and trust. Sapolsky notes the opposite of love is indifference, not hate. The amygdala's projection into the locus ceruleus drives autonomic intensity. )
- Sham emotions (sympathy is an emotion, the desire to help those in need. Steven Pinker suggests it may develop into a sham emotion to earn gratitide. Sapolsky adds that it can describe someone with the power to help, but who choses not to. Alternately it can indicate feeling sorry for someone elses pain while not understanding it, in contrast with empathy. Or it can mean the emotionally distanced sense of feeling for someone. Or the state of feeling their pain as if it were happening to you where it may cause such distress as to focus you onto alleviating you own distress.

,
revenge, or vengeance, is a doomsday machine emotion. In hunter-gatherer bands the major constraint on a relative or loved one being murdered was the 'guarantee' of revenge. Revenge pairs with the emotional signal honor. It must be advertised and hard to turn off. Traditional societies incorporate it into legal frameworks as retribution, a legitimate goal of criminal punishment. &
rage is a doomsday machine emotion of uncontrollable righteous anger. )
- The caprice of romance (romantic love is a passionate emotion reflecting the risky agreement to commit resources to the long term activity of raising children. The genes ensure that once a person has chosen, the critical-thinking pathways shut down. That is especially necessary for women to ignore the uncertainty - they become more passionately in love than men. For both partners initial separations remove the oxytocin (and vasopressin in men) and dopamine rewards from touching & hugging, generating withdrawal driving the couple closer. The same circuits, driven again by oxytocin signalling, encourage a mother to fall in love with her newborn baby. )

Suburban savanna
The African savanna is the environment where hunter-gatherers primarily evolved. Its grassland supported large herbivores that could be hunted easily across the plains. Clumps of Acacia trees: with short trunks, and broad bows; & rocks supported places to hide from large carnivores. Streams, especially important in times of drought, and paths add to the signals enabling orientation.

In situations where parents invest in the growth and memetic learning of their offspring the schematic grab bag can support optimizations to develop models, structures and actions to construct an adept adult.

Sirens' song
Hunter-gatherers is a lifestyle organized around a band of relatives, evolved in humans focused on capturing the cognitive niche in the African savanna. It is of great significance in shaping our minds: behaviors, emotions, creativity, intelligence; and developing survival strategies including use of fire and language, according to evolutionary psychologists. It was practiced by all humans, for most of Homo sapiens existence, until the emergence of farming, and still is by some isolated bands: Ju/'hoansi, New Guinea: Gebusi, Mae Enga; & Borneo head hunters, Maasai & Zulu warriors from Africa, Amazonians: Waorani, Jivaro; Brazilian and Venezuelan Yanomamo. Since the band moves on when it has depleted the resources in an area of land, the soil remains vibrant, but the large animals were typically placed in a position of stress from which they did not recover.

the participants, their
offspring and others in the group including the leaders now aims to develop plans and strategies which ensure effective coordination to improve the common good of the in-group. Pinker notes the evolved pressure of social rivalry associating power with leadership. Different evolved personality types reinforced during development provided hunter-gatherer bands with alternate adult capabilities for coping with the various challenges of the African savanna. As the situation changed different personalities would prove most helpful in leading the band. Big men, chiefs and leaders of early states leveraged their power over the flow of resources to capture and redistribute wealth to their supporters. As the environmental state changed and began threatening the polity's fitness, one leader would be abandoned, replaced by another who the group hoped might improve the situation for all. Sapolsky observes the disconnect that occurs between power hierarchies and wisdom in apes. In modern Anglo-American style corporations, which typically follow Malthus, and are disconnected from the superOrganism nest site, the goal of leadership has become detached from the needs of this broader polity, instead: seeking market and revenue growth, hiring and firing workers, and leveraging power to reduce these commitments further. Dorner notes that corporate executives show an appreciation of how to control a CAS. Robert Iger with personality types: Reformer, Achiever, Investigator; describes his time as Disney CEO, where he experienced a highly aligned environment, working to nurture the good and manage the bad. He notes something is always coming up. Leadership requires the ability to adapt to challenges while compartmentalizing.

people are emotions that are induced in response to other people's signals, are implemented by specific brain regions including: Prefrontal cortex, Insula cortex, Anterior cingulate cortex, Amygdala; receive lots of projections from interoceptive networks. Sapolsky asserts in the moments just before we prioritize a consequential act the process is less rational and autonomous than we assume. There are many significant signals from the prior seconds to minutes that effect social emotions: - Our brains respond subliminally to skin color very quickly: Amygdala activates, Fusiform face area activates; prior to the conscious stream activating the anterior cingulate and DLPFC which then inhibit the amygdala.
- Social dominance is culture independent and accurately subliminally assessed after a 40-millisecond exposure. Stable status relations activate the ventromedial prefrontal cortex and DLPFC, while a dynamic situation also activates the amygdala.
- People who are subliminally judged attractive by the medial orbitofrontal cortex are considered kinder, smarter and more honest. They are given more breaks.
- Faces and eyes in particular are most important subliminal cues. They are monitored by the fusiform. People respond more appropriately under the subliminal influence of eyes.
- Olfactory sensors send more direct projections to the limbic network than other sensory networks. Pheromones signal fear activating the amygdala.
- Observing pain responses in others results in empathy even among young children.
- Words are important emotional signals providing unconscious priming of social responses. Kahneman & Tversky demonstrated how the phrase '95% survival rate' is found to be a more acceptable choice than '5% death rate'. Sapolsky notes that prosocial word priming fosters cooperation with antisocial word priming doing the opposite.
- Cultural objects such as visible: flags, team badges; subliminally modify in-group outgroup decisions.
- The presence of women in a situation alters the responses of men: Increased risk-taking, more focus on luxuries, increased aggression; in circumstances where conflict is already encouraged but not when status is achieved prosocially.
- Physical environment shapes behavior as demonstrated by Philip Zimbardo and leveraged in broken windows policing.
- Bodily adjustments to sensory structures introduce adaptive complexity, with the brain being influenced to become more sensitive and alter the sensor networks to make some more sensitive. But these adaptations also vary culturally. Collectivist cultures focus on a visual scene's surrounding contextual information while people from individualistic cultures focus on the focal object!
's signals, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy. ,

It can be induced by natural selection when there is mutual survival benefit in group activities and cheating can be detected and discouraged. Humans, leveraging the cognitive niche, can particularly easily, build an evolved amplifier, through sharing information at little cost and significant benefit. But African savanna hunters similarly gain from sharing large game meat with other un-related altruistic group members since the meat would otherwise spoil before it could be eaten. ).

When it is repressed, for example by a strong moral sense (superego), it can sustain, inducing long term stress. , Gratitude is an emotion that sets the strength of the desire to reciprocate a favor based on the costs and benefits of the earlier gift. When a favor helps a lot and is costly to the giver we are very grateful. , Sympathy is an emotion, the desire to help those in need. Steven Pinker suggests it may develop into a sham emotion to earn gratitide. Sapolsky adds that it can describe someone with the power to help, but who choses not to. Alternately it can indicate feeling sorry for someone elses pain while not understanding it, in contrast with empathy. Or it can mean the emotionally distanced sense of feeling for someone. Or the state of feeling their pain as if it were happening to you where it may cause such distress as to focus you onto alleviating you own distress. , Guilt is an emotion which alerts us to the risk of cheating on a friend. To be culturally effective the individuals must have respect for the law. Guilt is associated with activation of the posterior cingulate cortex. . Trivers noted a
subtle way to cheat: recipricate but not enough. This
induces an arms race, in a war where both sides use the strategy of development and use of advanced weapon systems to gain an advantage, each advance induces the other side to respond with its own asymmetric advances. Neither side will necessarily gain the upper hand in which case the weapon systems themselves advance rapidly with little direct benefit for the combatants.
where a cheater detector and associated tit-for-tat is a winning iterative Prisoner's Dilemma strategy. Michigan political scientist Robert Axelrod programmed various proposed strategies into a program performing the Prisoner's Dilemma. Anatol Rapoport suggested the Tit for Tat strategy where the prisoner starts by cooperating but defects whenever the other prisoner has defected in the prior round. It is a simple strategy with little cognitive load. W. D. Hamilton worked with Axelrod adding real-world possibilities to the game situations. These included: - Signal errors where the prisoner's intent was different to the signal's interpretation: They acted to cooperate but appeared to request defection. This undermines the Tit for Tat strategy and forces the establishment of trust.
- Cost of adding detectors to monitor for signal errors and sham emotions.

Sham emotions
The cheating is most effective if it is unconscious and uses
sham generosity and friendship
to induce altruism benefits another organism at a cost to the behaver. It is differentiated from kin altruism, by Williams and Trivers, since it can apply between unrelated individuals. It can be induced by natural selection when there is mutual survival benefit in group activities and cheating can be detected and discouraged. Humans, leveraging the cognitive niche, can particularly easily, build an evolved amplifier, through sharing information at little cost and significant benefit. But African savanna hunters similarly gain from sharing large game meat with other un-related altruistic group members since the meat would otherwise spoil before it could be eaten.
and sham moral provides rules for identifying right from wrong. It develops in stages with children using play to work out rules of appropriate behavior. Kohlberg's 1950s experiments using children led him to conclude moral judgement is a cognitive process that develops in three stages. Sapolsky raises issues with the framework: Its a model, It does not apply to other cultures, Intuition & emotion are as significant as cognition, Moral reasoning doesn't predict moral actions; and notes the capacity of the frontal cortex to regulate emotions and behavior is far more predictive. The marshmallow test, performed on three to six year olds, actually predicted their subsequent SAT scores at high school, social success and lack of aggression, and forty years on more PFC activation during a frontal task and a lower BMI! Jonathan Haidt argues people's moral decisions are rationalizations rather than using reasoning. anger is an emotion which protects a person who has been cheated by a supposed friend. When the exploitation of the altruism is discovered, Steven Pinker explains, the result is a drive for moralistic aggression to hurt the cheater. Anger is mostly experienced as a rapid wave that then quickly dissipates. When it is repressed, for example by a strong moral sense (superego), it can sustain, inducing long term stress. to gain reparations

guard against sham emotions can then be used to attack real

Trivers comcludes that this cognitive is the ability to orchestrate thought and action in accordance with internal goals according to Princeton's Jonathan Cohen. arms race, in a war where both sides use the strategy of development and use of advanced weapon systems to gain an advantage, each advance induces the other side to respond with its own asymmetric advances.

Evolution disconnects the emotions are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism. from the intellect to ensure that emotional

unconscious physiological signals, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy.

integrated design and separated strategic actions. This is
contrary to the romantic idea of a vestigial emotional animal
lurking within the rational man. The actual design also
protects to some extent against sham
emotions.

Loneliness; but both people in a partnership are aware that they

it's not likely that the perfect match will be in the proximate
pool of partners when there is only a limited time to do the

fitness is, according to Dawkins, a suitcase word with at least five meanings in biology: - Darwin and Wallace thought in terms of the capacity to survive and reproduce, but they were considering discrete aspects such as chewing grass - where hard enamel would improve the relative fitness.
- Population geneticists: Ronald Fisher, Sewall Wright, J.B.S. Haldane; consider selection at a locus where for a genotype: green eyes vs blue eyes; one with higher fitness can be identified from genotypic frequencies and gene frequencies, with all other variations averaged out.
- Whole organism 'integrated' fitness. Dawkins notes there is only ever one instance of a specific organism. Being unique, comparing the relative success of its offspring makes little sense. Over a huge number of generations the individual is likely to have provided a contribution to everyone in the pool or no one.
- Inclusive fitness, where according to Hamilton, fitness depends on an organism's actions or effects on its children or its relative's children, a model where natural selection favors organs and behaviors that cause the individual's genes to be passed on. It is easy to mistakenly count an offspring in multiple relative's fitness assessments.
- Personal fitness represents the effects a person's relatives have on the individual's fitness [3]. When interpreted correctly fitness [4] and fitness [5] are the same.
issue. But
they must commit to someone!
Pinker notes that romantic
love is a passionate emotion reflecting the risky agreement to commit resources to the long term activity of raising children. The genes ensure that once a person has chosen, the critical-thinking pathways shut down. That is especially necessary for women to ignore the uncertainty - they become more passionately in love than men. For both partners initial separations remove the oxytocin (and vasopressin in men) and dopamine rewards from touching & hugging, generating withdrawal driving the couple closer. The same circuits, driven again by oxytocin signalling, encourage a mother to fall in love with her newborn baby. is another passionate emotion are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal.

It is not
surprising since the complex commitment: Trust, Marriage, Children; is significant and
risky for both partners. Indeed societies extend the
emotional commitment with a contract that is traditionally
difficult to break.
Punishment of grief
Pinker notes that grief can seem illogical. He proposes a
solution: Grief is an internal Doomsday
Machine to constrain us to invest in protecting and

the premise "I am nice and in control." Pinker offers
George Orwell's rationalization from '1984': "The secret of

with a power to learn from past mistakes." Trivers argues
that in a world of walking
lie detectors the best strategy is to believe your own lies is an emotion, the ability to hide your intentions from your self so as to effectively hide them from others. .
Family Values
Pinker introduces this chapter as largely about inborn motives
that place people in conflict with one another. Social
relations between: family, lovers, rivals,
friends, acquaintances,
allies & enemies.
These motives can also identify relations that make us human.
Donald Brown's Human Universals, found in all cultures is how we do and think about things, transmitted by non-genetic means as defined by Frans de Waal. CAS theory views cultures as operating via memetic schemata evolved by memetic operators to support a cultural superorganism. Evolutionary psychology asserts that human culture reflects adaptations generated while hunting and gathering. Dehaene views culture as essentially human, shaped by exaptations and reading, transmitted with support of the neuronal workspace and stabilized by neuronal recycling. Damasio notes prokaryotes and social insects have developed cultural social behaviors. Sapolsky argues that parents must show children how to transform their genetically derived capabilities into a culturally effective toolset. He is interested in the broad differences across cultures of: Life expectancy, GDP, Death in childbirth, Violence, Chronic bullying, Gender equality, Happiness, Response to cheating, Individualist or collectivist, Enforcing honor, Approach to hierarchy; illustrating how different a person's life will be depending on the culture where they are raised. Culture: - Is deployed during pregnancy & childhood, with parental mediation. Nutrients, immune messages and hormones all affect the prenatal brain. Hormones: Testosterone with anti-Mullerian hormone masculinizes the brain by entering target cells and after conversion to estrogen binding to intracellular estrogen receptors; have organizational effects producing lifelong changes. Parenting style typically produces adults who adopt the same approach. And mothering style can alter gene regulation in the fetus in ways that transfer epigenetically to future generations! PMS symptoms vary by culture.

distinct thoughts and feelings are subjective models: sad, glad, mad, scared, surprised, and compassionate; of the organism and its proximate environment, including ratings of situations signalled by broadly distributed chemicals and neural circuits. These feelings become highly salient inputs, evolutionarily associated, to higher level emotions encoded in neural circuits: amygdala, and insula. Deacon shows James' conception of feeling can build sentience. Damasio, similarly, asserts feelings reveal to the conscious mind the subjective status of life: good, bad, in between; within a higher organism. They especially indicate the affective situation within the old interior world of the viscera located in the abdomen, thorax and thick of the skin - so smiling makes one feel happy; but augmented with the reports from the situation of the new interior world of voluntary muscles. Repeated experiences build intermediate narratives, in the mind, which reduce the salience. Damasio concludes feelings relate closely and consistently with homeostasis, acting as its mental deputies once organisms developed 'nervous systems' about 600 million years ago, and building on the precursor regulatory devices supplied by evolution to social insects and prokaryotes and leveraging analogous dynamic constraints. Damasio suggests feelings contribute to the development of culture: - As motives for intellectual creation: prompting detection and diagnosis of homeostatic deficiencies, identifying desirable states worthy of creative effort.
- As monitors of the success and failure of cultural instruments and practices
- As participants in the negotiation of adjustments required by the cultural process over time
about kin & non-kin.
Kith and Kin
Love is an emotion, which generates a feeling of pleasure at a genetic relative's well-being and pain in their harm. An inseminated human female is genetically a full relative of her partner since she carries his germ-line gametes. From any of their pooled gene's perspective the offspring have a one-in-two chance of including the specific gene. Hence love supports kin selection driven by the selfish actions of genes. Emotions, including love and anger, help drive the interactions between people. Compassionate love also supports the symbiotic partnership of true friends built on fairness and trust. Sapolsky notes the opposite of love is indifference, not hate. The amygdala's projection into the locus ceruleus drives autonomic intensity. of kin is a straight

driven by kin altruism, is the property that since kin share genes natural selection will improve the replicator's selfish goals by supporting the survival of such relatives. Improving the chances of survival of non-kin is hard to explain with a gene preservation theory. Why help a competitive gene? Trivers explanation of reciprocal altruism shows the special conditions under which it can occur. .
It is less obvious how it can design compassionate indicates an emotional state where resonance with someone else's distress leads one to help them. The Dalai Lama stresses we must feel compassion for ourselves and others. Tara Brach sees compassion as our capacity to relate in a tender and sympathetic way to what we perceive. Meditation focused on feeling love for the suffering, strengthens compassion by activating the neuron networks for parental love for a child: ACC, insula, striatum, PAG, orbitofrontal cortex; and inducing a reduction in areas responsible for negative emotions. love for

Altruism is beneficial to gene replication in this situation. Love supports the agent's prioritization of appropriate altruistic strategies. E. O. Wilson was originally an advocate of kin selection but subsequently concluded that there is no mechanism by which it can operate. He abandoned kin selection and now asserts neo-group selection is responsible for the effects. Sapolsky describes an array of strategies used to identify kin: - Genetically shaped pheromonal signatures. Rodents leverage the immune systems MHC super variable gene regions to develop unique signals. The more similar the signals are the closer is the relative. Pregnancy triggers adult neurogenesis in the olfactory system of rat mothers to allow them to learn the smell of their newborn.

survival of their shared genes. Kinship keeps hunter-gatherer is a lifestyle organized around a band of relatives, evolved in humans focused on capturing the cognitive niche in the African savanna. It is of great significance in shaping our minds: behaviors, emotions, creativity, intelligence; and developing survival strategies including use of fire and language, according to evolutionary psychologists. It was practiced by all humans, for most of Homo sapiens existence, until the emergence of farming, and still is by some isolated bands: Ju/'hoansi, New Guinea: Gebusi, Mae Enga; & Borneo head hunters, Maasai & Zulu warriors from Africa, Amazonians: Waorani, Jivaro; Brazilian and Venezuelan Yanomamo. Since the band moves on when it has depleted the resources in an area of land, the soil remains vibrant, but the large animals were typically placed in a position of stress from which they did not recover.

Kinship holds their villages together. But such relationships can't be free, fair and equal at the same time. As such families are subversive to centralized organizations including states and religions. Such organizations use incest laws and marriage rules to limit the strategic power of marriage to create threats.

Genetic relatives are unlikely to kill one another, except for parents of infants, when
sustaining the new born will place intolerable stress is a multi-faceted condition reflecting high cortisol levels. Dr. Robert Sapolsky's studies of baboons indicate that stress helps build readiness for fight or flight. As these actions occur the levels of cortisol return to the baseline rate. A stressor is anything that disrupts the regular homeostatic balance. The stress response is the array of neural and endocrine changes that occur to respond effectively to the crisis and reestablish homeostasis. - The short term response to the stressor
- activates the amygdala which: Stimulates the brain stem resulting in inhibition of the parasympathetic nervous system and activation of the sympathetic nervous system with the hormones epinephrine and norepinephrine deployed around the body, Activates the PVN which generates a cascade resulting in glucocorticoid secretion to: get energy to the muscles with increased blood pressure for a powerful response. The brain's acuity and cognition are stimulated. The immune system is stimulated with beta-endorphin and repair activities curtail. In order for the body to destroy bacteria in wounds, pro-inflammatory cytokines increase blood flow to the area. The induced inflammation signals the brain to activate the insula and through it the ACC. But when the stressor is
- long term: loneliness, debt; and no action is necessary, or possible, long term damage ensues. Damage from such stress may only occur in specific situations: Nuclear families coping with parents moving in. Sustained stress provides an evolved amplifier of a position of dominance and status. It is a strategy in female aggression used to limit reproductive competition. Sustained stress:
- Stops the frontal cortex from ensuring we do the harder thing, instead substituting amplification of the individual's propensity for risk-taking and impairing risk assessment!
- Activates the integration between the thalamus and amygdala.
- Acts differently on the amygdala in comparison to the frontal cortex and hippocampus: Stress strengthens the integration between the Amygdala and the hippocampus, making the hippocampus fearful.
- BLA & BNST respond with increased BDNF levels and expanded dendrites persistently increasing anxiety and fear conditioning.
- Makes it easier to learn a fear association and to consolidate it into long-term memory. Sustained stress makes it harder to unlearn fear by making the prefrontal cortex inhibit the BLA from learning to break the fear association and weakening the prefrontal cortex's hold over the amygdala. And glucocorticoids decrease activation of the medial prefrontal cortex during processing of emotional faces. Accuracy of assessing emotions from faces suffers. A terrified rat generating lots of glucocorticoids will cause dendrites in the hippocampus to atrophy but when it generates the same amount from excitement of running on a wheel the dendrites expand. The activation of the amygdala seems to determine how the hippocampus responds.
- Depletes the nucleus accumbens of dopamine biasing rats toward social subordination and biasing humans toward depression.
- Disrupts working memory by amplifying norepinephrine signalling in the prefrontal cortex and amygdala to prefrontal cortex signalling until they become destructive. It also desynchronizes activation in different frontal lobe regions impacting shifting of attention.

It depends on and supports evolved amplifiers which introduce instability and problems with sustainability of the populations that depended on it, unlike the earlier hunting and gathering. Today the uncertainty can be hedged, although third world farmers' businesses are undermined by first world agricultural policy. J.R. McNeill explains the sustainability issue: "all farming is a struggle against the depletion of soil nutrients. Crops absorb nutrients; these are eaten by people or animals; then they spend shorter or longer periods of time in human or animal bodies, before returning to the soil. If these nutrients, in one manner or another, return to farmers' fields, then a nutrient cycle can last indefinitely. If they do not, then those fields gradually lose nutrient and over time produce less and less food - unless some intervention such as fertilizer counteracts the nutrient loss." However, McNeill notes three notable exceptions: Egypt until the Aswan High Dam, Southern China, Medieval Europe; "each ecologically successful over long periods of time." Their success resulted from trial and error and favorable circumstances.

Parents and children
Decisions integrates situational context, state and signals to prioritize among strategies and respond in a timely manner. It occurs in all animals, including us and our organizations: - Individual human decision making includes conscious and unconscious aspects. Situational context is highly influential: supplying meaning to our general mechanisms, & for robots too. Emotions are important in providing a balanced judgement. The adaptive unconscious interprets percepts quickly supporting 'fast' decision making. Conscious decision making, supported by the: DLPFC, vmPFC and limbic system; can use slower autonomy. The amygdala, during unsettling or uncertain social situations, signals the decision making regions of the frontal lobe, including the orbitofrontal cortex. The BLA supports rejecting unacceptable offers. Moral decisions are influenced by a moral decision switch. Sleeping before making an important decision is useful in obtaining the support of the unconscious in developing a preference. Word framing demonstrates the limitations of our fast intuitive decision making processes. And prior positive associations detected by the hippocampus, can be reactivated with the support of the striatum linking it to the memory of a reward, inducing a bias into our choices. Prior to the development of the PFC, the ventral striatum supports adolescent decision making. Neurons involved in decision making in the association areas of the cortex are active for much longer than neurons participating in the sensory areas of the cortex. This allows them to link perceptions with a provisional action plan. Association neurons can track probabilities connected to a choice. As evidence is accumulated and a threshold is reached a choice is made, making fast thinking highly adaptive. Diseases including: schizophrenia and anorexia; highlight aspects of human decision making.
- Organisations often struggle to balance top down and distributed decision making: parliamentry government must use a process, health care is attempting to improve the process: checklists, end-to-end care; and include more participants, but has systemic issues, business leaders struggle with strategy.

childrearing are inherently about allocating the parents' Carlo Rovelli resolves the paradox of time.
Rovelli initially explains that low level physics does not
include time:
- A present that is common throughout the universe does not exist
- Events are only partially ordered. The present is
localized
- The difference between past and future is not foundational.
It occurs because of state that through our blurring appears
particular to us
- Time passes at different speeds dependent on where we are and how fast we travel
- Time's rhythms are due to
the gravitational field
- Our quantized physics shows neither
space nor time, just processes transforming physical
variables.
- Fundamentally there is no time. The basic equations
evolve together with events, not things
Then he
explains how in a physical world without time its perception can
emerge:
- Our familiar time emerges
- Our interaction with the world is partial, blurred,
quantum indeterminate
- The ignorance determines the existence of thermal time
and entropy that quantifies our uncertainty
- Directionality of time is real
but perspectival. The entropy of the world in
relation to us increases with our thermal time. The
growth of entropy distinguishes past from future: resulting in
traces and memories
- Each human is a
unified being because: we reflect the world, we
formed an image of a unified entity by
interacting with our kind, and because of the perspective
of memory
- The variable time: is one
of the variables of the gravitational field.
With our scale we don't
register quantum fluctuations, making space-time

Pinker views Trivers's parent-offspring
conflict is Robert Trivers theory to explain the allocation of parental resources to various offspring, from the implications of genetics on the family. Observing that children want to take more than what their parents want to give Trivers concluded a parent should aim to transfer resources depending on the relative benefits to each child and the costs, since each child has the same percentage of the parent's genes. But each child shares only fifty percent of their genes with their siblings so should aim to get resources until the benefit to the others is twice the cost to the child. And the parent may keep back some resources for allocation to further planned offspring. A variety of conflicts ensue: - In the womb the fetus tries to capture nutrients from the mother at the expense of future children. It ties up the mother's insulin to increase the blood sugar available to it and placing the mother at risk of diabetes. Fathers can assist their offspring in this 'fight with the mother' by supplying imprinted genes that help the offspring capture resources.
- At birth mothers must decide whether to let the baby die. This practice is cross cultural but is considered a depravity by present Western culture. That is probably due to the West having captured a majority of the world's resources for centuries.
- Infants use cuteness to encourage parental investment. A mother's attachment delays until it is clear that the baby will live.
- Infants cry to demand milk. Until weaned the mother won't ovulate limiting her future reproductive potential.
- Young children are in conflict with their father over access to their mother.
- Children are in a position to develop paradoxical tactics to push for more resource allocation.
- Older children may have sexual conflicts with their parents, especially their fathers. Fathers compete with sons for sexual partners in many societies. But this competition is not for their mother.
- Adult children may conflict with their parents over allocation of family resources. This has led to murder.
- Parents attempt to train children to assist the parent's social interests. The implication is that children are wary of their parent's suggestions and typically pay more attention to the advice of their peer group according to Judith Harris.
- Parents sell or trade their children. The price paid for a daughter will likely depend on her virginity. Hence fathers take an interest in their daughters' sexuality.

distinction asserts that babies are collections of instincts which parents socialize into competent members of society. ; for explaining the allocation of resources
between parents and their children. Trivers theory
suggests that children will resist having their personalities describes the operation of the mind from the perspective of psychological models and tests based on them. Early 'Western' models of personality resulted in a simple segmentation noting the tension between: individual desires and group needs, and developing models and performing actions. Dualistic 'Eastern' philosophies promote the legitimacy of an essence which Riso & Hudson argue is hidden within a shell of personality types and is only reached by developing presence. The logic of a coherent essence is in conflict with the evolved nature of emotions outlined by Pinker. Terman's studies of personality identified types which Friedman and Martin link to healthy and unhealthy pathways. Current psychiatric models highlight at least five key aspects: - Extroversion-introversion - whether the person gains mental dynamism from socializing or retiring
- Neuroticism-stability - does a person worry or are they calm and self-satisfied
- Agreeableness-antagonism - is a person courteous & trusting or rude and suspicious
- Conscientiousness-un-directedness - is a person careful or careless
- Openness-non-openness - are they daring or conforming
altered
by their parents. Testing
this hypothesis shows that parents have very little effect
on personality. Identical twins separated at birth have
virtually identical personalities. Adoptive siblings in
the same home are as different as random children are.
Pinker concludes Trivers's theory suggests childrearing will
always be partly a question of ethics and politics as well as
psychology and biology.
Brothers and sisters
Parents generally favor older children over younger. That
makes sense since hunter-gatherer is a lifestyle organized around a band of relatives, evolved in humans focused on capturing the cognitive niche in the African savanna. It is of great significance in shaping our minds: behaviors, emotions, creativity, intelligence; and developing survival strategies including use of fire and language, according to evolutionary psychologists. It was practiced by all humans, for most of Homo sapiens existence, until the emergence of farming, and still is by some isolated bands: Ju/'hoansi, New Guinea: Gebusi, Mae Enga; & Borneo head hunters, Maasai & Zulu warriors from Africa, Amazonians: Waorani, Jivaro; Brazilian and Venezuelan Yanomamo. Since the band moves on when it has depleted the resources in an area of land, the soil remains vibrant, but the large animals were typically placed in a position of stress from which they did not recover.

The second child must adopt an alternative strategy. They
are typically appeasers, cooperators and revolutionaries and are
receptive to change.
The strategies adopted by the children are leveraged by them as
adults due to honed skills, sunk costs and the continued need to
compete with their parents.
Pinker notes brother sister incest is sex between family members. Pinker notes that it is universally avoided between brothers and sisters. This is probably an adaptation since it is universally avoided among long-lived animals and brings increased risks of expression of recessive genes. Father's genes suffer limited genetic consequence and a potential bonus from father daughter incest which does occur.

leverage of nepotism is a broad pattern of kin solidarity. Relatives are natural allies. Hunter-gatherer societies are organized around clans of relatives. Kinship holds their villages together. But such relationships can't be free, fair and equal at the same time. As such families are subversive to centralized organizations including states and religions. Such organizations use incest laws and marriage rules to limit the strategic power of marriage to create threats. .
Men and women
Pinker notes there is a powerful battle between the sexes.
Men and The stages of development of the human female, including how her brain changes and the
impacts of this on her 'reality' across a full life span:
conception, infantile
puberty, girlhood,
juvenile pause, adolescence, dating years, motherhood, post-menopause; are

how emotions are processed
by women compared to men.

women have very different
sexual natures because the sexual desires &
dispositions that is adaptive in evolutionary biology is a trait that increased the number of surviving offspring in an organism's ancestral lineage. Holland argues: complex adaptive systems (CAS) adapt due to the influence of schematic strings on agents. Evolution indicates fitness when an organism survives and reproduces. For his genetic algorithm, Holland separated the adaptive process into credit assignment and rule discovery. He assigned a strength to each of the rules (alternate hypothesis) used by his artificial agents, by credit assignment - each accepted message being paid for by the recipient, increasing the sender agent's rule's strength (implicit modeling) and reducing the recipient's. When an agent achieved an explicit goal they obtained a final reward. Rule discovery used the genetic algorithm to select strong rule schemas from a pair of agents to be included in the next generation, with crossing over and mutation applied, and the resulting schematic strategies used to replace weaker schemas. The crossing over genetic operator is unlikely to break up a short schematic sequence that provides a building block retained because of its 'fitness'; In Deacon's conception of evolution, an adaptation is the realization of a set of constraints on candidate mechanisms, and so long as these constraints are maintained, other features are arbitrary.

emotions are low level fast unconscious agents distributed across the brain and body which associate, via the amygdala and rich club hubs, important environmental signals with encoded high speed sensors, and distributed programs of action to model: predict, prioritize guidance signals, select and respond effectively, coherently and rapidly to the initial signal. The majority of emotion centered brain regions interface to the midbrain through the hypothalamus. The cerebellum and basal ganglia support the integration of emotion and motor functions, rewarding rhythmic movement. The most accessible signs of emotions are the hard to control and universal facial expressions. Emotions provide prioritization for conscious access given that an animal has only one body, but possibly many cells, with which to achieve its highest level goals. Because of this, base emotions clash with group goals and are disparaged by the powerful. Pinker notes a set of group selected emotions which he classes as: other-condemning, other-praising, other-suffering and self-conscious emotions. Evolutionary psychology argues evolution shaped human emotions during the long period of hunter-gatherer existence in the African savanna. Human emotions are universal and include: Anger, Appreciation of natural beauty, Contempt, Disgust, Embarrassment, Fear, Gratitude, Grief, Guilt, Happiness, Honor, Jealousy, Liking, Love, Moral awe, Rage, Romantic love, Lust for revenge, Passion, Sadness, Self-control, Shame, Sympathy, Surprise; and the sham emotions and distrust induced by reciprocal altruism. : Romantic love is a passionate emotion reflecting the risky agreement to commit resources to the long term activity of raising children. The genes ensure that once a person has chosen, the critical-thinking pathways shut down. That is especially necessary for women to ignore the uncertainty - they become more passionately in love than men. For both partners initial separations remove the oxytocin (and vasopressin in men) and dopamine rewards from touching & hugging, generating withdrawal driving the couple closer. The same circuits, driven again by oxytocin signalling, encourage a mother to fall in love with her newborn baby. ; to

almost all the investing; causes two cascades of consequences:
- A single male can fertilize more than one female.
This generates competition between males for the available
females. They can fight each other or court the
females for access.
- Reproductive success of males depends on how many females
they mate with. So females
are more discriminating, looking for signals of good genes
and, in humans and birds, a willingness to feed and protect
the offspring. Males woo females and mate with all that

Its grassland supported large herbivores that could be hunted easily across the plains. Clumps of Acacia trees: with short trunks, and broad bows; & rocks supported places to hide from large carnivores. Streams, especially important in times of drought, and paths add to the signals enabling orientation. :

& through the capacity for self-control is an emotion, the ability to trade current for future use of resources. Hunter-gatherers are likely to benefit from immediate use of resources, since they have little opportunity to store them. Otherwise the resources, including men & women to reproduce with, may be lost, stolen or degrade. Since the intense drive for men to breed with any available woman can lead to costly disputes and lack of focus on strategic activities, self-control is promoted by parents and other powerful group leaders. But the frontal cortex can promote willpower to increase self-control. Genes also allocate more resources early in the life-cycle to avoid compounding failure to leverage resources to reproduce, with agent accidents and deaths. .
Husbands and wives
Polygyny allows powerful men to have multiple wives. This is beneficial to both these men and women, who get access to the resources and genes of the successful males. In situations where power is distributed more evenly, men seek to have polygyny outlawed, creating a cartel which reduces the power of women and the elite males. is beneficial to
women. When power is captured by a small elite, these
males benefit from acceptance of polygyny. Anti-polygyny
laws can be seen as a cartel like strategy by the majority of
men to limit the power of women and elites.
Both sexes commit adultery. Women can trade sex for
resources. And they may aim for the best husband to

Men want faithful wives who have long years of child

Beauty is a signal of health, indicating a lack of parasites is a long term relationship between the parasite and its host where the resources of the host are utilized by the parasite without reciprocity.

Subliminal priming with words did not depend on the shape of the word. The fusiform gyrus was able to process the abstract identity of a word without caring if it was upper or lower case. While high up in the cortex it can operate below the level of conscious experience. It contributes to social emotions with: - Its face area being more activated by faces with in-group skin color.
- It activating when shown pictures of cars in automobile aficionados.
- It activating when shown pictures of birds in birdwatchers; since it really recognizes examples of items from an individual's emotionally salient categories.

in all cultures is how we do and think about things, transmitted by non-genetic means as defined by Frans de Waal. CAS theory views cultures as operating via memetic schemata evolved by memetic operators to support a cultural superorganism. Evolutionary psychology asserts that human culture reflects adaptations generated while hunting and gathering. Dehaene views culture as essentially human, shaped by exaptations and reading, transmitted with support of the neuronal workspace and stabilized by neuronal recycling. Damasio notes prokaryotes and social insects have developed cultural social behaviors. Sapolsky argues that parents must show children how to transform their genetically derived capabilities into a culturally effective toolset. He is interested in the broad differences across cultures of: Life expectancy, GDP, Death in childbirth, Violence, Chronic bullying, Gender equality, Happiness, Response to cheating, Individualist or collectivist, Enforcing honor, Approach to hierarchy; illustrating how different a person's life will be depending on the culture where they are raised.

Men's jealousy is unsophisticated. They don't feel
comfortable with sharing wives. They worry about sexual
betrayal. Women are more sophisticated since they may beneficially share husbands.
Real risk for women is that her partner diverts resources to
other women, which they see as an emotional betrayal.
Pinker argues that killing a wife who leaves her husband, is a doomsday machine response:
"Don't think of leaving."
Men treat wives as property. Established codes and laws of
property have been used to control women. Marriage is structured
as a transfer of property from father to groom. The
groom's family pays for the transfer in 96% of the 76% of
societies that include payments when people get married.
Adultery is treated as a tort. Jealous rage at the
discovery of a woman's adultery is accepted allowing justifiable
homicide.
Rivals
Pinker notes that people strive to build signals, is an emergent capability which is used by cooperating agents to support coordination & rival agents to support control and dominance. In eukaryotic cells signalling is used extensively. A signal interacts with the exposed region of a receptor molecule inducing it to change shape to an activated form. Chains of enzymes interact with the activated receptor relaying, amplifying and responding to the signal to change the state of the cell. Many of the signalling pathways pass through the nuclear membrane and interact with the DNA to change its state. Enzymes sensitive to the changes induced in the DNA then start to operate generating actions including sending further signals. Cell signalling is reviewed by Helmreich. Signalling is a fundamental aspect of CAS theory and is discussed from the abstract CAS perspective in signals and sensors. In AWF the eukaryotic signalling architecture has been abstracted in a codelet based implementation. To be credible signals must be hard to fake. To be effective they must be easily detected by the target recipient. To be efficient they are low cost to produce and destroy. that demonstrate
their DNA (DNA), a polymer composed of a chain of deoxy ribose sugars with purine or pyrimidine side chains. DNA naturally forms into helical pairs with the side chains stacked in the center of the helix. It is a natural form of schematic string. The purines and pyrimidines couple so that AT and GC pairs make up the stackable items. A code of triplets of base pairs (enabling 64 separate items to be named) has evolved which now redundantly represents each of the 20 amino-acids that are deployed into proteins, along with triplets representing the termination sequence. Chemical modifications and histone binding (chromatin) allow cells to represent state directly on the DNA schema. To cope with inconsistencies in the cell wide state second messenger and evolved amplification strategies are used. 's fitness is, according to Dawkins, a suitcase word with at least five meanings in biology: - Darwin and Wallace thought in terms of the capacity to survive and reproduce, but they were considering discrete aspects such as chewing grass - where hard enamel would improve the relative fitness.
- Population geneticists: Ronald Fisher, Sewall Wright, J.B.S. Haldane; consider selection at a locus where for a genotype: green eyes vs blue eyes; one with higher fitness can be identified from genotypic frequencies and gene frequencies, with all other variations averaged out.
- Whole organism 'integrated' fitness. Dawkins notes there is only ever one instance of a specific organism. Being unique, comparing the relative success of its offspring makes little sense. Over a huge number of generations the individual is likely to have provided a contribution to everyone in the pool or no one.
- Inclusive fitness, where according to Hamilton, fitness depends on an organism's actions or effects on its children or its relative's children, a model where natural selection favors organs and behaviors that cause the individual's genes to be passed on. It is easy to mistakenly count an offspring in multiple relative's fitness assessments.
- Personal fitness represents the effects a person's relatives have on the individual's fitness [3]. When interpreted correctly fitness [4] and fitness [5] are the same.

natural selection:
- Dominance signals the power to hurt a rival. Maynard Smith & Parker explain that in group situations females compete for food and males compete for females. Maleness is a huge factor for violence. Fighting to the death is costly for all participants so instead they indicate:
- Size and weapons to demonstrate who will win. Males who are, or look like, better fighters: Large heads, Big men, Height; gain in dominance.
- Political acumen to demonstrate they won't be pushed around and have the support of other powerful groups. Dominant males push other rivals aside and gain interest of females, enabling themselves to replicate more. Being a signal its authenticity can be challenged and so must be defended to remain credible. Hotheads leverage the doomsday machine to constrain rational challenges. Bands and cultures leverage honor. Youth and lack of resources reduce the power of rivals' political constraints.

Michigan political scientist Robert Axelrod programmed various proposed strategies into a program performing the Prisoner's Dilemma. Anatol Rapoport suggested the Tit for Tat strategy where the prisoner starts by cooperating but defects whenever the other prisoner has defected in the prior round. It is a simple strategy with little cognitive load. W. D. Hamilton worked with Axelrod adding real-world possibilities to the game situations. These included: - Signal errors where the prisoner's intent was different to the signal's interpretation: They acted to cooperate but appeared to request defection. This undermines the Tit for Tat strategy and forces the establishment of trust.
- Cost of adding detectors to monitor for signal errors and sham emotions.

cope with cheaters. Reciprocal altruism likely developed
because successful hunting of large herbivores generates huge
surpluses of food that must be shared broadly before the meat rots is a universal human emotion. Pinker notes it has its own facial expression and is codified in food taboos. The mind must be associated with the proximate environment and parents minimize the risk for their omnivorous children by teaching them what foods to eat and what to avoid. The children's minds are initially receptive to trying all foods but their brains subsequently lock in on the foods they have experienced. These parental choices are affected by schematic influence on what has been beneficial. Adolescent's brain developments undermine these constraints enabling intergroup transfers. Disgust is modulated by the insula cortex which projects signals to the amygdala. Adult humans merge moral and physical disgust enabling metaphorical out grouping. .
But Pinker notes that relationships between friends and spouses are not built on
reciprocal altruism, which builds unhappy shallow
relationships. Instead similarities, enabling symbiosis is a long term situation between two, or more, different agents where the resources of both are shared for mutual benefit. Some of the relationships have built remarkable dependencies: Tremblaya's partnership with citrus mealybugs and bacterial DNA residing in the mealybug's genome, Aphids with species of secondary symbiont bacteria deployed sexually from a male aphid sperm reservoir and propagated asexually by female aphids only while their local diet induces a dependency. If the power relations and opportunities change for the participants then they will adapt and the situation may transform into separation, predation or parasitism. , appears to be

By motivating behavior that has an immediate cost, a moral emotion can allow greater benefits later, including reciprocity and intimidating bullies by demonstrations of spiteful behavior. which act as tests and

In hunter-gatherer bands the major constraint on a relative or loved one being murdered was the 'guarantee' of revenge. Revenge pairs with the emotional signal honor.

- Increases the numbers of offspring carrying genes for war,
- More than offsets the impacts of deaths of combatants on
average for the gene pool. Indeed the deaths increase
the odds of getting an additional wife for the

And:
- Men are more willing to go to war when their group is
secure in food, ensuring they can sustain the extra women
they capture and children they intend to produce.
- Females don't naturally go to war, since their genes gain
nothing and they risk death. So societies find sending
women to war disconcerting.
- Foragers typically have similar weapons and tactics are goals and actions which respond to the actions of the enemy in a combat, rather than focusing on ones own strategic direction.

Pinker proposes the patterns of intervals music is a complex emergent capability supported by sexual selection and generating pleasure. It transforms the sensing of epiphenomena: Contour, Rhythm, Tempo, Timbre; to induce salient representations: Harmony, Key, Loudness, Melody, Meter, Pitch, and perceptions: Reverberation - echo; which allow musicians: Elton John, Elvis Presley; to show their fitness: superior coordination, creativity, adolescent leadership, stamina; true for birds and humans. Levitin showed that listening to music causes a cascade of brain regions to become activated in a particular order: auditory cortex, frontal regions, such as BA44 and BA47, and finally the mesolimbic system, culminating in the nucleus accumbens. And he found the cerebellum and basal ganglia were active throughout the session. He argues music mimics some of the features of language and conveys some of the same emotions. The brain regions pulse with the beat and predict the next one. As the music is heard it is modeled and generates dopamine rewards for matching each beat and noting creative jokes in the rhythm. The cerebellum finds pleasure in adjusting itself to stay synchronized. represents become

and the agent programming framework (Smiley) that supports its
operation.
Example test system statements are included.
To begin a test a test statement is loaded into Smiley while
Smiley executes on the Perl
interpreter.
Part of Smiley's Perl code focused on setting up the
infrastructure is included bellow.
The setup includes:
- Loading the 'Meta file'
specification,
- Initializing the Slipnet,
and Workspaces and loading them
- So that the Coderack
can be called.
The Coderack, which is the focus of a separate
page of the Perl frame then schedules and runs the codelets
that are invoked by the test statement structures.

how human adolescence in humans supports the transition from a juvenile configuration, dependent on parents and structured to learn & logistically transform, to adult optimized to the proximate environment. And it is staged, encouraging male adolescents to escape the hierarchy they grew up in and enter other groups where they may bring in: fresh ideas, risk taking; and alter the existing hierarchy: Steve Jobs & Steve Wozniak, Bill Gates & Paul Allen; while females become highly focused on friendships and communications. It marks the beginning of Piaget's formal operational stage of cognitive development. The limbic, autonomic and hormone networks are already deployed and functioning effectively. The frontal cortex has to be pruned: winning neurons move to their final highly connected positions, and are myelinated over time. The rest dissolve. So the frontal lobe does not obtain its adult configuration and networked integration until the mid-twenties when prefrontal cortex control becomes optimal. The evolutionarily oldest areas of the frontal cortex mature first. The PFC must be iteratively customized by experience to do the right thing as an adult. Adolescents: - Don't detect irony effectively. They depend on the DMPFC to do this, unlike adults who leverage the fusiform face area.
- Regulate emotions with the ventral striatum while the prefrontal cortex is still being setup. Dopamine projection density and signalling increase from the ventral tegmentum catalyzing increased interest in dopamine based rewards. Novelty seeking allows for creative exploration which was necessary to move beyond the familial pack. Criticisms do not get incorporated into learning models by adolescents leaving their risk assessments very poor. The target of the dopamine networks, the adolescent accumbens, responds to rewards like a gyrating top - hugely to large rewards, and negatively to small rewards. Eventually as the frontal regions increase in contribution there are steady improvements in: working memory, flexible rule use, executive organization and task shifting. And adolescents start to see other people's perspective.
- Drive the cellular transformations with post-pubescent high levels of testosterone in males, and high but fluctuating estrogen & progesterone levels in females. Blood flow to the frontal cortex is also diverted on occasion to the groin.
- Peer pressure is exceptionally influential in adolescents. Admired peer comments reduce vmPFC activity and enhance ventral striatal activity. Adults modulate the mental impact of socially mean treatment: the initial activation of the PAG, anterior cingulate, amygdala, insula cortex; which generate feelings of pain, anger, and disgust, with the VLPFC but that does not occur in adolescents.
- Feel empathy intensely, supported by their rampant emotions, interest in novelty, ego. But feeling the pain of others can induce self-oriented avoidance of the situations.

Reading and writing present a conundrum. The reader's
brain contains neural networks tuned to reading. With
imaging a written word can be followed as it progresses from the
retina through a functional chain that asks: Are these letters?
What do they look like? Are they a word? What does it sound
like? How is it pronounced? What does it mean? Dehaene
explains the importance of
education in tuning the brain's networks for reading as
well as good strategies for teaching reading and countering dyslexia. But
he notes the reading
networks developed far too recently to have directly evolved.
And Dehaene asks why humans are unique in developing
reading and culture.
He explains the cultural
engineering that shaped writing to human vision and the exaptations and neuronal structures that
enable and constrain reading and culture.

But natural selection has improved our fitness by representing this perception, in our minds, as an unchanging thing, as explained by Pinker. Dehaene explains the object modeling and construction process within the unconscious and conscious brain. Mathematicians view anything that can be defined and used in deductive reasoning and mathematical proofs as an object. These mathematical objects can be values of variables, allowing them to be used in formulas.

It allows for schematic strategies to be iteratively blended with environmental signals to solve the logistical issues of migrating newly built and transformed sub-agents. That is needed to achieve the adult configuration of the agent and optimize it for the proximate environment. Smiley includes examples of the developmental phase agents required in an emergent CAS. In situations where parents invest in the growth and memetic learning of their offspring the schematic grab bag can support optimizations to develop models, structures and actions to construct an adept adult. In humans, adolescence leverages neural plasticity, elder sibling advice and adult coaching to help prepare the deploying neuronal network and body to successfully compete.

the ability to deliver more warriors is the key. Pinker

results of global conflict and woke up to find other
alternatives. Knowledge,
literacy and exchange of ideas are judged key pacifiers.

prior history of hierarchic farming emerged several times and various places, probably first around 11,000 years ago. It depends on and supports evolved amplifiers which introduce instability and problems with sustainability of the populations that depended on it, unlike the earlier hunting and gathering. Today the uncertainty can be hedged, although third world farmers' businesses are undermined by first world agricultural policy. J.R. McNeill explains the sustainability issue: "all farming is a struggle against the depletion of soil nutrients. Crops absorb nutrients; these are eaten by people or animals; then they spend shorter or longer periods of time in human or animal bodies, before returning to the soil. If these nutrients, in one manner or another, return to farmers' fields, then a nutrient cycle can last indefinitely. If they do not, then those fields gradually lose nutrient and over time produce less and less food - unless some intervention such as fertilizer counteracts the nutrient loss." However, McNeill notes three notable exceptions: Egypt until the Aswan High Dam, Southern China, Medieval Europe; "each ecologically successful over long periods of time." Their success resulted from trial and error and favorable circumstances.

It was sponsored by Mexico, the Ford and Rockefeller Foundations, with leadership from Norman Borlaug and it built on the work of geneticist, Nazareno Strampelli. The improved production leveraged the development of: - High yielding varieties of wheat and rice based on:
- High rates of nitrogen metabolism (cross breading, genetic engineering) allowing high yield when combined with
- Strong short stems to resist bending and

through the Sven Beckert describes the historic transformation of the
growing, spinning, weaving, manufacture of cotton goods and
their trade over time. He describes the rise of a first global
commodity, its dependence on increasing: military power, returns for
the control points in the value delivery system(VDS), availability of land
and labor to work it including slaves.
He explains how cotton offered the opportunity for
industrialization further amplifying the productive capacity of
the VDS and the power of the control points. This VDS was quickly
copied. The increased capacity of the industrialized
cotton complex adaptive system (CAS) required more labor to
operate the machines. Beckert describes the innovative introduction of wages
and the ways found to
mobilize industrial labor.
Beckert describes the characteristics of the industrial cotton
CAS which made it flexible enough to become globally interconnected.
Slavery made the production system so cost effective that all
prior structures collapsed as they interconnected. So when
the US civil war
blocked access to the major production nodes in the
American Deep South the CAS began adapting.
Beckert describes the global
reconstruction that occurred and the resulting destruction of the traditional ways
of life in the global countryside. This colonial expansion
further enriched and empowered the 'western' nation states. Beckert explains
how other countries
responded by copying the colonial strategies and creating
the opportunities for future armed conflict among the original
colonialists and the new upstarts.
Completing the adaptive

the colonized global south and how over time they joined

nodes and creating the current global CAS

Following our summary of Beckert's book, RSS comments from the
perspective of CAS theory. The transformation of
disconnected peasant farmers,
pastoral warriors and their lands into a supply chain for a
highly profitable industrial CAS required the development over
