A further turn is to be found in some "unmasking" accounts of natural science, which aim to show that its pretensions to deliver the truth are unfoun… - Bernard Williams

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 important areas of our thought and in traditional interpretations of those areas; they sense that it has something to do with truth; and (no doubt driven by the familiar desire to say something at once hugely general, deeply important, and reassuringly simple) they extend their worry to the notion of truth itself.

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.

There continue to be complex debates about what Nietzsche understood truth to be. Quite certainly, he did not think, in pragmatist spirit, that beliefs are true if they serve our interests or welfare: we have just seen some of his repeated denials of this idea. The more recently fashionable view is that he was the first of the deniers, thinking that there is no such thing as truth, or that truth is what anyone thinks it is, or that it is a boring category that we can do without. This is also wrong, and more deeply so. Nietzsche did not think that the ideal of truthfulness went into retirement when its metaphysical origins were discovered, and he did not suppose, either, that truthfulness could be detached from a concern for the truth. Truthfulness as an ideal retains its power, and so far from his seeing truth as dispensable or malleable, his main question is how it can be made bearable.
