A broad overview of Intelligence

Put another way:
The world is knowable, but it is knowable through the categories of the knower, which were shaped by evolution.
So evolutionary adaptation by natural selection results in a partial correspondence, a kind of isomorphism between the structure of the world and the organization of the knower. On that account, organisms do not make theories of the world, they are theories of the world.

The biosphere = a deeply nested array of INTELLIGENT/COGNITIVE SYSTEMS
- All these INFERENTIAL-REPRESENTATION-STRATEGIES or intelligent/cognitive systems are COMPETING for statistical survival.
- All these cognitive-survival-strategies are competing to be the best-fit cognitive-survival-strategy within the larger context of their ever evolving and mutually-adaptive sibling-level(organism/cell/gene) competitors.
- This competition between cognitive-survival-strategies also plays itself out repeatably at numerously nested cognitive-sub-system levels such as cellular and gene levels.
- All theses mutually-adaptive layers of cognitive-survival-strategy, from gene/cell through to biosphere, participate to varying degrees in a globally adaptive gestalt of evolutionary-level-mixing crosstalk/feedback.
- Intelligence/cognition is ubiquitous throughout nature
- Intelligent/cognitive organisms are themselves assemblages of nested Intelligent/cognitive sub-systems
- Many organisms are themselves cognitive-cogs nested within larger more globally distributed biological or social intelligent/cognitive systems.
1- INTELLIGENCE = REPRESENTATIONAL efficiency/simplicity/minimalism
- The most intelligent REPRESENTATIONAL system is the simplest one that effectively meets the strategic challenge at hand.
- Representational COMPRESSION = representational choices that are more direct and more isomorphic
- Representational COMPOSITION = representational choices that can be easily transposed, scaled, repurposed or otherwise reused via a simply set of rule driven manipulations
2- INTELLIGENCE = ACTIONABLE INFERENCE
… . deductive - inductive - abductive
3- INTELLIGENCE = KEY STRATEGY
- Biologically-embodied statistical trial and error search or a multi-cellular distributed redundancy survival-niche trial and error search strategy.

“Soon there will be computers of such huge power that we will be using for tools who’s output we might not comprehend and we will be using them in domains of critical social importance
Unless we start thinking very carefully about the way we program and engage with their intelligence… . our demise will be a consequence of owning a tool which we are not qualified to own”
Supersizing the Mind - key concepts
Principle of Ecological Balance
one … that given a certain task environment there has to be a match between the complexities of the agent’s sensory, motor, and neural systems
second… that there is a certain balance or task-distribution between morphology, materials, control,and environment.
The “matching” of sensors, morphology, motor system, materials,controller, and ecological niche yields a spread of responsibility for efficient adaptive response in which “not all the processing is performed by the brain, but certain aspects of it are taken over by the morphology,materials, and environment [yielding] a ‘balance’ or task-distribution between the different aspects of an embodied agent” (see Pfeifer et al.}
In such cases, the details of embodiment may take over some of the work that would otherwise need to be done by the brain or the neural network controller, an effect that can aptly be described as “morphological computation.”
I.E - Once the body itself is“equipped” with the right kind of passive dynamics, powered walking can be brought about in a remarkably elegant and energy-efficient way. In essence, the tasks of actuation and control have now been massivelyreconfigured so that powered, directed locomotion can come about by systematically pushing, damping, and tweaking a system in whichpassive-dynamic effects still play a major role. The control design isdelicately geared to utilize all the natural dynamics of the passive base-line, and the actuation is consequently efficient and fluid.
Some of the core flavor of such a solution is captured by the broadernotion of “ecological control,” where an ecological control system is one in which goals are not achieved by micromanaging every detail of the desired action or response but by making the most of robust reliable sources of relevant order in the bodily or worldly environmentof the controller. In such cases,
part of the “processing” is taken over by the dynamics of the agent-environment interaction, and only sparse neural control needs to be exerted when the self-regulating and stabilizing properties of the natural dynamics can be exploited. (Pfeiferet al.) -page 6-7
Principle of Inhabited/embodied/embedded Interaction
- The exploitation of passive-dynamic effects or “nontrivial causal spread”
this characteristic occurs whenever something we might have expected to be achieved by a certain well-demarcated system turns out to involve the exploitation of more far-flung factors and forces
Principle of Ecological Assembly (PEA)
the canny cognizer tends to recruit, on the spot, whatever mix of problem solving resources will yield an acceptable result with a minimum of effort - page 13

When historian Charles Weiner found pages of Nobel Prize-winning physicist Richard Feynman’s notes, he saw it as a “record” of Feynman’s work. Feynman himself, however, insisted that the notes were not a record but the work itself.
In Supersizing the Mind , Andy Clark argues that our thinking doesn’t happen only in our heads but that “certain forms of human cognizing include inextricable tangles of feedback, feed-forward and feed-around loops: loops that promiscuously criss-cross the boundaries of brain, body and world.” The pen and paper of Feynman’s thought are just such feedback loops, physical machinery that shape the flow of thought and enlarge the boundaries of mind.
Drawing upon recent work in psychology, linguistics, neuroscience, artificial intelligence, robotics, human-computer systems, and beyond, Supersizing the Mind offers both a tour of the emerging cognitive landscape and a sustained argument in favor of a conception of mind that is extended rather than “brain-bound.”
The importance of this new perspective is profound. If our minds themselves can include aspects of our social and physical environments, then the kinds of social and physical environments we create can reconfigure our minds and our capacity for thought and reason.

or put another way
We don’t just map/model/fit the world of phenomenon onto the strategic-goal-seeking representational-fabric of our brain mechanics.
Much more importantly, throughout eons of evolution, the world has pre-configured our brains so as to optimize the receptivitive-fabric/power of our brains to synch up with, to enmesh with the fabric of reality in such a way that both the brain and reality have evolved as mutual expressions/extensions of one another.
It is this bridge of mutual adaptive, evolution-synchronized, shared-fabric between the human brain and the universe of phenomena that symbiotically bootstraps both into the networked realm of universal creative mind.
This reminds me of the old saying:
First man creates tools then his tools reshape him.
this transposes to:
First the universe creates man then man reshape his universe.
Reality seems to engulf both in an endless self-referential repeating loop!
- (a strange loop)
put yet another way
The universe is
an integrated, self-refereniial, chain-reactive
morphogenic-field-array of processes
all organically entangled in mutually adaptive feedback loops
of network synchronizing interplay
the whole universal dance ubiquitously underpinned by
standing waves of pure probability.
standing waves of mutually-reenforcing survival-niche probability interactions
standing waves of self-replication mediated via symbiotic probability networks
a universal probability-diven complexity gradient-trap
an irrepressible self-reenforcing mesh of nested probability feedback loops
relentless single-minded probability flowing like water
into a valley of increasingly complex synchronicity
inextricably swelling the river of collective inter-nodal consciousness
Maybe Albert Einstein was wrong when he said:
“God does not play dice”
maybe
God is the dice!

And at the other end of the cognitive scale
The cognitive power embodied in cultural activity systems

Cultural activity systems have cognitive properties of their own that are different from the cognitive properties of the individuals who participate in them.
