Memory is everything. Without it we are nothing.

The task of neural science is to explain behaviour in terms of the activities of the brain. How does the brain marshall its millions of individual nerve cells to produce behaviour, and how are these cells influenced by the environment...? The last frontier of the biological sciences – their ultimate challenge – is to understand the biological basis of consciousness and the mental processes by which we perceive, act, learn, and remember.

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.

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

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.

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

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.
