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.

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

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

As you know, in most areas of science, there are long periods of beginning before we really make progress.

I really like the city of Vienna. I like its art, its music and its architecture. In short, I like the culture that Vienna represents. What really captures me is the period around 1900 - the time of Freud, Schnitzler and Klimt. This is the period in which the modern view of mind was born.

The problem for many people is that we cannot point to the underlying biological bases of most psychiatric disorders. In fact, we are nowhere near understanding them as well as we understand disorders of the liver or the heart.

I have on the one hand a hatred and on the other a yearning for Vienna. I left when I was nine years old because I was Jewish. And even before 1938, the anti-Semitism in Austria was probably deeper than it was in Germany or in other European countries.
