The brain is the last and grandest biological frontier, the most complex thing we have yet discovered in our universe. It contains hundreds of billio… - James Watson

Crick, however, was right. Our discovery put an end to a debate as old as the human species: Does life have some magical, mystical essence, or is it, like any chemical reaction carried out in a science class, the product of normal physical and chemical processes? Is there something divine at the heart of a cell that brings it to life? The double helix answer that question with a definitive No.

Right now, at my institute in the US we are working on gene-caused failures in brain development that frequently lead to autism and schizophrenia. We may also find that differences in these respective brain development genes also lead to differences in our abilities to carry out different mental tasks. In some cases, how these genes function may help us to understand variations in IQ, or why some people excel at poetry but are terrible at mathematics. All too often people with high mathematical abilities have autistic traits. The same gene that gives some people such great mathematical abilities may also lead to autistic behaviour. This is why, in studying autism and schizophrenia, we believe that we shall come very close to a better understanding of intelligence and, therefore, of the differences in intelligence.

Never do anything that bores you. My experience in science is that someone is always telling to do something that leaves you flat. Bad idea. I'm not good enough to do something I dislike. In fact, I find it hard enough to do something that I like. … Constantly exposing your ideas to informed criticism is very important, and I would venture to say that one reason both of our chief competitors failed to reach the Double Helix before us was that each was effectively very isolated.
