Steven Pinker on Evolutinary Psychology

Variation is partly due to being genetic

Evoltionary Psychology - study of the universal human nature. Put most differences in people due to the environemnt, not genes. It depends on where you grew up.

Underneath all the variation, there is something more abstact with more rules of a language. A universal language is the stamp of those hidden rules. If you look superficiary at muscle movement and what they say, behavior is all over the map. But motives are all the same, usually.

Motions/patterns of thought is the nature of behavior.

Key insight of AI -- its hard to get computers to do intelligent things. They can't do waht we take for granted (walking without stepping over shadows). Gives appreciation to complexity to our brain, and have to ask where it came from? Could it be natual selection? what is evolutions role?

intelligence is a generic property, not something that came from nowhere. Evolution wasn't enough to evolve our brain.

Kin selection - key to understanding our social relationships. Our blood relatives are more important than strangers, why? Why are airports clogged at christmas? Whats up with strategic marriages, wars over succession ..

The existance of consciousness gives us the idea that there's something more to life... is it beyond neural science? is it beyond science?

what was life like before the big bang? what do you mean time only started when the big bang started? its a circle we fall into, which makes me think this thinking game is making us a victim , into thinking we don't need a purpose because our mind can't grasp it.

bottom line -- the brain is a limited organ. It was designed to finish a finite set of tasks, problems that are life and death matters ... we can't hold 10,000 words in short term or mentally rotate objects in the 4th dimension or solve complex issues like free will... so stop trying!
