“The statement that ‘there is no such thing as truth’ is itself a truth statement, and implies that it is truer than its opposite, the statement that ‘truth exists’. If we had no concept of truth, we could not state anything at all, and it would even be pointless to act. There would be no purpose, for example, in seeking the advice of doctors, since there would be no point in having their opinion, and no basis for their view that one treatment was better than another. None of us actually lives as though there were no truth. Our problem is more with the notion of a single, unchanging truth.”
