Neuroscience about Newton

Quotes from Michael S. Gazzaniga, Who’s in Charge?: Free Will and the Science of the Brain

p. 98 “In moment-to-moment activity, the interpreter [in the brain] is always dealing  with the changing inputs from sites in the brain where activity is going on.  Sitting under the apple tree, Isaac Newton, indulging in that most human traits to constantly seek explanations and causes for things,  asked himself, ‘Why did the apple fall down?  Hmmmm … Nothing pushed it. Why doesn’t it go up?’ Newton was engaging in two different types of processing concerned with causality,  and we have found one type occurs in right hemisphere, and the other in the left.”

p. 99 “So when Newton observed that the apple fell but perceived no observable interaction that caused it, he was using his right hemisphere. For other animals, that is the end of the story. But it was not good enough for Newton. He went to employ causal inference, the application of logical rules, which, as you may have guessed, is a bailiwick of the left hemisphere.”

I love it. It is even cooler than postmodern.
