As Roland Barthes said, those who do not re-read condemn themselves to reading the same story everywhere: "they recognize what they already think and… - Bernard Williams

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 unfounded, because of social forces that control its activities. Unlike the case of history, these do not use truths of the same kind; they do not apply science to the criticism of science. They apply the social sciences, and typically depend on the remarkable assumption that the sociology of knowledge is in a better position to deliver truth about science than science is to deliver truth about the world.

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.

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.
