The question of the place of science in knowledge, and in society, and in life, is not a scientific question. Science confers no special authority, it confers no authority at all, for the attempt to answer a nonscientific question. It is not for science to say whether science belongs in morality and politics and art. Those are philosophical matters, and science is not philosophy, even if philosophy has since its beginnings been receptive to science. Nor does science confer any license to extend its categories and its methods beyond its own realms, whose contours are of course a matter of debate. The credibility of physicists and biologists and economists on the subject of the meaning of life—what used to be called the ultimate verities, secularly or religiously constructed—cannot be owed to their work in physics and biology and economics, however distinguished it is.
