Evolution and Ethics, Revisited by Gertrude Himmelfarb.
They persuade the world of what is false by urging upon it what is true.” That is John Henry Newman in The Idea of a University (1852) referring to the sciences of his day, which threatened to dominate and even overwhelm theological education in the university. A science’s teaching might be true in its proper place but fallacious “if it be constituted the sole exponent of all things in heaven and earth, and that, for the simple reason that it is encroaching on territory not its own, and undertaking problems which it has no instruments to solve.”
While Newman’s notion of science was far broader than ours, including even painting and music, his description of the overreach of science is still apt. We now have a term — “scientism” — for that fallacy, exemplified, as has been demonstrated in these pages, by Richard Dawkins’s pronouncement that genes “created us, body and mind,” and Edward O. Wilson’s claim that biology is the “basis of all social behavior.” If scientism has become so prevalent, it is partly because of the emergence of new sciences, each encroaching, as Newman said, on “territory not its own” (invading, we would now say, the turf of others), and each professing to comprehend (in both senses of that word) the whole. Intended as an epithet, the term has been adopted as an honorific by some of its practitioners. A chapter in the book Every Thing Must Go: Metaphysics Naturalized (2007) by three philosophers is entitled “In Defense of Scientism.”
