It is hard to predict how science is
going to turn out, and if it is really good science it is impossible to predict.
If the things to be found are actually new, they are by definition unknown in
advance. You cannot make choices in this matter. You either have science or you
don’t, and if you have it you are obliged to accept the surprising and
disturbing pieces of information, along with the neat and promptly useful
bits. The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead.
