McGilchrist starts from Ancient Greek civilization which is already problematic because we should be looking way earlier
Jaynes starts from an archeology perspective, way before McG starts (with civilization, literature, culture -- which is game over for Jaynes)
If the problems arise with the start of language, they can't have started in Ancient Athens. McGilchrist thinks that Athens is a mostly right-hemisphere society that needs more left
But if we're interested in phylogenetic questions, like the creations of categories in the first place, McGilchrist just starts way too late for this
Yaklovelian torque: Chimpanzees
If macular vision is controlled by the left hemisphere then it must start way before any of the stuff from the last few thousand years
McG believes he's arguing against Jaynes but he's actually providing more details/argument FOR Jaynes view
He gets Jaynes wrong, in part because of this schizophrenia issue. He believes that schizophrenia is "too much left brain" but this in some ways seems unlikely.
McGilchrist believes anger starts in the left hemisphere
Left is about delaying/distancing/planning which allows instrumental violence in pursuit of ultimate ends
Instrumental (proactive) Bivs reactive aggression is a huge distinction
Rage can be distinguish anger
Nietzsche: Punishment starts with reactive hitting children
Jaynes has two modes:
Bicameral, which ranges from everyone has direct access to gods all the way to mediated through strict hierarchies (like Egyptians)
Consciousness which is really more like metacognition/introspective awareness
Bicameral mind has its benefits: the long-view (not really right?) of building pyramids and such require the bicameral mind… so there are benefits (which McG totally denies)
McG presents an almost uninterrogated right brain supremacy view
How to steelman this argument?
It's a polemic against a left-brain society, cognitive science, rationalism, Effective Altruism, demotion of emotion
In the process of trying to level the right/left brain focus in science (generally), he gets Jaynes wrong and misses important distinctions and goes too far with what is good about right and bad about left
Overall timelines
Alpha male, hierarchy, high reactive violence. Rewards go to the strong.
Sociability is rewarded but not as much as violence.
Eventually, with coalition forming (tool use? Planning? language?) the tables turn. A critical threshold. Now sociability (planning to kill the alpha) is rewarded more than violence.
This is an example of bottom-up pressure overcoming top-down. Introducing the chaos of empowering weaker males disrupts the previous order, and this leads to a revolution.
Now any leader must not only appease but form stronger coalitions. It rewards planning and sociability.
Probably also involves deception.
Planned violence as cold and calculated, so it rewards left brain.
Differential Susceptibility
Work at fleshing out differential susceptibility (orchid vs dandelion children) in relation to survival, socialibility, and resilience
Rule inversion: Thriving at extremes, like bullied kid who becomes CEO
Orchid children are highly sensitive to their environment, especially to the quality of parenting they receive. If neglected, orchid children promptly wither--but if they are nurtured, they not only survive but flourish [ ] Isabela flesh out
Franz De Waal
De Waal's work with Bonobos (vs chimps) and role of repair in group dynamics/cohesion and survival
There's the role of tool-use as providing an opportunity for lesser males in the troop to form coalitions and become more powerful than the alpha; social capacities and processes become selected for with this innovation (tools) such that violence/aggression/physical power is no longer the most critical for selection
BUT! De Waal's work (and others) with Bonobos but also chimps shows that "repair" or "reconciliation" processes (post violent outbursts/fights) are also key for determining the extent of closeness and collaborative effectiveness of a troop; those groups who could remain closely bonded (through processes like grooming), in turn, were healthier, happier, and stronger. And functioned better at the level of the group, but also in comparison to other troops who were less cohesive and therefore faired worse in inter-group fights
Timelines
Genes code for things that are and will change and these revolutions happen
Timing matters: critical periods for transformations that allow for them or do nothing at all
Part of the unique contribution of Bryan's work is to tell several example-stories of the Darwin account
We need to think and maybe organize our thinking (at times) around the fractal nature and iteratively constraining properties and fractal nature of:
(Physics time)
(Chemistry time)
Genetic evolutionary time
Culutural time
Ontogenetic time
Each of the above levels of change across time are hierarchically embedded and partially constrained by the level above (there should be no circular causality because time's arrow goes in only one direction… presumably)
Example of Janus-faces
Chimpanzee aggression in order to repair
Childhood development (apparently excitatory) is prompted/facilitated by inhibitory system
Learning by pruning. Pruning as selection.
GABA switches from excitatory to inhibitory
Hemoglobin switches direction/polarity
Dose-dependent responses? Alcohol/kratom in low/high dosage? Smokers modulating breath length?
Recombination: individual as having to shift to get around various filters. Butterflies: different environment. Babies, adolescents.
6/2c1c Revolutions make the Environment into Fuel
- e.g., oxygen is the product of photosynthesis… until it's not
- then used for cellular respiration that are far more efficient
- results may be mixed though (not always positive tradeoff)
6/2c1d Revolutions occur when far-from-equilibrium states persist
- Bitcoin and energy usage
