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

Vienna is relatively small. And it had wonderful salons, opportunities for people to get together. There was a lot of interaction between scientists and non-scientists, between Jews and non-Jews, between artists, writers and scientists, including medical scientists.

It is this potential for plasticity of the relatively stereotyped units of the nervous system that endows each of us with our individuality.

Memory is everything. Without it we are nothing.

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 don't think biology is replacing the feeling experienced through art. Biology is capable of giving additional insights. It's a parallel, not a substitutive process.

There are cells in the brain that respond to faces. This is one of the reasons that I deal with portraiture. We can learn a lot about our perception of facial expression from the behavior of these cells.

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

In art, as in science, reductionism does not trivialize our perception - of color, light, and perspective - but allows us to see each of these components in a new way.

Not only Freud but artists and writers were also interested in the unconscious. It was medicine that made the first steps toward modernity.

After the war, the Austrians just denied their role in it all. They didn't teach it in school. But since 1990 they have openly acknowledged their role in the Holocaust and I feel more comfortable in Austria. I feel a sort of reconciliation.

Has it ever struck you ... that life is all memory, except for the one present moment that goes by you so quickly you hardly catch it going? It’s really all memory ... except for each passing moment.
