Up From Dragons - Chapters

Chapters

1. Cosmic Mirror: The questions of who and what humans are explored in terms of the history of the universe, life and humankind as when looking in a mirror.
2. Up from Dragons: Modern human genes arose when humans evolved as hunter-gatherers. But in the last 120,000 years humans have changed from hunter-gatherers to hi-tech citizens. The book seeks to answer why and how.
3. Neurons Unlimited: The brain is neurally plastic (NP) – evolution left open the function of human neurons. The capacity of its neurons to engage in imagination extends its potential to think and feel.
4. Superbrain: The prefrontal cortex (PC) is the brain's "conductor". It directs using inner representations as prompts which organize the brain's "orchestra" of neural “talents”.
5. Mind-Engine: Cognition depends upon brain waves that bind through synchronization of diverse brain areas into mental unity. The prefrontal cortex controls this unification of the brain.
6. Neural Revolution: The large sized human brain has extensive "blank" cortex available for processing nonevolved skills. But acquiring such skills requires that the brain’s neural networks get “trained”—which the prefrontal cortex does by acting as a “cortical catalyst”.
7. Machiavellian Neurons: Humans like other apes live in social groups that split and reform. Humans are novel in their ability to decouple these social and personal bonds from direct sensory contact. The human brain does this by carrying around its social group as an "inner troop within our heads".
8. The Troop within Our Heads: Humans think they are free—but this troop within their heads rules human thoughts, feelings and actions. Due to it humans feel guilt, shame, pride and self-consciousness.
9. Our Living Concern: Underlying human experience are mindmakers. One such mindmaker is the anterior cingulate as it creates attention to what is done. It underlies not only social consciousness, but pain, and a sense of reality.
10. Doing the Right Thing: Our sense of right and wrong arises from our origins as social apes. Morality is a byproduct of the troop within our heads that is created by the orbitofrontal cortex mindmaker. This limits human freedom by preventing psychopathic-like actions.
11. Where Memories are Made: The human sense of identity arises from the need of the brain to experience a past linked to the present. Here, the mindmaker is the hippocampus. It underlies memory and the sense of continuity of self, other and place.
12. What Are We?: Mindmakers are not consciousness but they make it possible. They become the consciousness of "I" and "will" by embodiment. The human brain embodies not only its body extension, but its “troop within its head” and the inner orchestration done by its prefrontal cortex.
13. Of Human Bonding: The change that turned apes into humans was the ability to decouple social and personal bonds from everyday contact. This allowed new kinds of bonds such as those of marriage, in-law kin, culture and religion.
14. The Symbolic Brain: Symbols enabled this decoupling of bonds. Symbols are cognitive stand-ins—a wedding ring stands in for a marriage bond. The prefrontal cortex generates symbols. This enabled hunter-gatherer genes to develop new forms of social life including that of modern people.
15. Lucy and Kanzi: The symbol making potential of the prefrontal cortex arose to enable extended family bonds across the African savannah. “Gifted environments” also arose created by adults so young brains could be helped to learn and enrich their minds with symbols.
16. The Runaway Species: Homo brains expanded to be good parents. Successful brains selected partners with brains with which they could best raise children. A runaway selection resulted between brain size, mate selection and skilled parenting.
17. The Billion-Hour Journey: That modern people are not hunter-gatherers is due to mindware – the mind expanding systems of symbols – that evolved in the last 120,000 years. The process started slow, but then “bootstrapped” itself and accelerated. It now underlies the thoughts and feelings of modern huma
18. Third Millennium Brain: The rewriting of the brain's potentials that started in the past still continues. “Braintech” is arising and will enhance humans even more. It is suggested that humans knowing that their origins lie in their brains, rather than ancient myth, will gain Brain Rights and enter a new Era—that of the Brain.
