Only two centuries ago, we could explain everything about everything, out of pure reason, and now most of that elaborate and harmonious structure has come apart before our eyes. We are dumb..... We have discovered how to ask important questions, and now we really do need, as an urgent matter, some answers. We now know that we cannot do this any longer by searching our minds, for there is not enough there to search, nor can we find the truth by guessing at it or by making up stories for ourselves. We cannot stop where we are, stuck with today's level of understanding, nor can we go back. I do not see that we have any real choice in this, for I can see only the one way ahead. We need science, more and better science, not for its technology, not for leisure, not even for health and longevity, but for the hope of wisdom which our kind of culture must acquire for its survival. - Lewis Thomas, 1979
