Deniers do not get their views just from simple mistakes about language and truth. Rather, they believe that there is something to worry about in imp… - Bernard Williams

Two currents of ideas are very prominent in modern thought and culture. On the one hand, there is an intense commitment to truthfulness--or, at any rate, a pervasive suspiciousness, a readiness against being fooled, an eagerness to see through appearances to the real structures and motives that lie behind them. Always familiar in politics, it stretches to historical understanding, to the social sciences, and even to interpretations of discoveries and research in the natural sciences.

Nietzsche ... did not settle for a demure civic conversation in the style of Richard Rorty's ironist, or saunter off with the smug nod that registers a deconstructive job neatly done. He was aware that his own criticisms and exposures owed both their motivation and their effect to the spirit of truthfulness. His aim was to see how far the values of truth could be revalued, how they might be understood in a perspective quite different from the Platonic and Christian metaphysics which had provided their principal source in the West up to now.

Those who say that all historical accounts are ideological constructs (which is one version of the idea that there is really no historical truth) rely on some story which must itself claim historical truth. They show that supposedly "objective" historians have tendentiously told their stories from some particular perspective; they describe, for example, the biasses that have gone into constructing various histories of the United States. Such an account, as a particular piece of history, may very well be true, but truth is a virtue that is embarrassingly unhelpful to a critic who wants not just to unmask past historians of America but to tell us that at the end of the line there is no historical truth. It is remarkable how complacent some "deconstructive" histories are about the status of the history that they deploy themselves.
