Exact knowledge is the enemy of vitalism.

Trying to determine the structure of a protein by UV spectroscopy was like trying to determine the structure of a piano by listening to the sound it made while being dropped down a flight of stairs.

There is no scientific study more vital to man than the study of his own brain. Our entire view of the universe depends on it.

A busy life is a wasted life.

One of the most frightening things in the Western world, and in this country in particular, is the number of people who believe in things that are scientifically false. If someone tells me that the earth is less than 10,000 years old, in my opinion he should see a psychiatrist.

I also suspect that many workers in this field [molecular biology] and related fields have been strongly motivated by the desire, rarely actually expressed, to refute vitalism.

A good scientist values criticism almost higher than friendship: no, in science criticism is the height and measure of friendship.
