Of all philosophical doctrines relativism surely gets the worst press. It is routinely described by its critics as "foolish", "simple-minded", "sophomoric", or "obviously self-refuting." It has been blamed for everything from rising crime to falling rates of literacy. The received view among a large part of the philosophical establishment is that it was decisively refuted by Plato almost two and half thousand years ago. And in modern times many illustrious Champions of Reason, including Karl Popper, Hilary Putnam, Jürgen Habermas, and Donald Davidson, have all sought to slay once and for all what Richard Rorty labeled "the relativist menace." But this fact in itself should give us pause. For as Alasdair MacIntyre says:
"Nothing is perhaps a surer sign that a doctrine embodies some not-to-be-neglected truth than that in the course of the history of philosophy it should have been refuted again and again. Genuinely refutable doctrines only need to be refuted once."
The two main species of relativism are usually described as "moral relativism", which asserts the relativity of moral values, and "cognitive relativism" which asserts the relativity of truth. Some form of moral relativism strikes many people, including professional philosophers, as somewhat plausible, or at least not very easy to refute. A relativistic view of truth, however, is widely thought of as a doctrine for the birds. After all, surely, some statements are just true, period; others are just false. Anyone who thinks otherwise should go and jump off a high building and see if there is any possible world in which the prediction that that this will be bad for their health turns out not to be true.
In my view, though, cognitive relativism is, at bottom, just a form of pragmatism, a philosophical outlook that is generally treated with much greater respect. I believe an effective way of showing this is by means of an analogy. First, though, a brief clarification regarding what relativists assert is in order.
