It is hard to predict（预言）how science is going to turn out, and whether it is really good science, it is impossible to predict. If the things to be found are actually new, they must be unknown in advance. You cannot make choices on this matter. You either have science or you don't and if you have it you have to accept the surprising and disturbing pieces of information, along with the neat and useful bits.
The only solid piece of scientific truth about which I feel totally confident is that we don't know enough about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, a clear piece of news. It would have amazed the brightest minds of the 18th century to be told by any of us how little we know and how strange the way ahead seems. In earlier times, they either pretended to understand how things worked or simply made up stories to give answers. Now that we have begun exploring seriously, we are catching sight of how huge the questions are, and how far from being answered. Because of this, we are sorry. It is not so bad being ignorant（无知的）if you are totally ignorant; the hard thing is knowing in some details the reality of ignorance, the worst spots and here and there the not so bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted.
