No one on this thread, up till now, has mentioned an arbitrarily changing or anything goes model of truth. Perhaps you misunderstood what I meant by 'gerrymandered.' All I meant was that the referent of 'truth' in physical or biological terms may be an extremely complicated and ugly array of truth-bearing states. Conceding that doesn't mean that we should allow 'truth' (or any word) to be used completely anarchically.
