“What is truth?”. This provokes perplexity because, on the one hand, it demands an answer of the form, “Truth is such–and-such,” but on the other hand, despite hundreds of years of looking, no acceptable answer of that kind has ever been found. We’ve tried truth as “correspondence with the facts,” as “provability,” as “practical utility,” and as “stable consensus”; but all turned out to be defective in one way or another — either circular or subject to counterexamples. Reactions to this impasse have included a variety of theoretical proposals. Some philosophers have been led to deny that there is such a thing as absolute truth. Some have maintained (insisting on one of the above definitions) that although truth exists, it lacks certain features that are ordinarily attributed to it — for example, that the truth may sometimes be impossible to discover. Some have inferred that truth is intrinsically paradoxical and essentially incomprehensible. And others persist in the attempt to devise a definition that will fit all the intuitive data.

But from Wittgenstein’s perspective each of the first three of these strategies rides roughshod over our fundamental convictions about truth, and the fourth is highly unlikely to succeed. Instead we should begin, he thinks, by recognizing (as mentioned above) that our various concepts play very different roles in our cognitive economy and (correspondingly) are governed by defining principles of very different kinds. Therefore, it was always a mistake to extrapolate from the fact that empirical concepts, such as red or magnetic or alive stand for properties with specifiable underlying natures to the presumption that the notion of truth must stand for some such property as well.
