One of the wonderful things about Internet is its like a salon. It brings people together from different intellectual walks of life.

I went to medical school after having decided to do so somewhere between my junior and senior year at Harvard - very late. I initially wanted to be an intellectual historian.

I see psychoanalysis, art and biology ultimately coming together, just like cognitive psychology and neuroscience have merged.

Biology is a way of approaching the truth about the mind. In biology most people don't tackle problems at the level of complexity that psychoanalysis does. But psychoanalysis has a degree of uncertainty about it. A psychoanalyst may have some deep insights, but cannot, at the moment, run experiments to establish whether it's really the truth.

Memory is everything. Without it we are nothing.

Truth has many dimensions, and the way you arrive at truth in complex situations is through many perspectives.

Life is sort of a circle. You come back to a lot of the interests that you had early in life.
