I have often wondered how proponents of the doctrine of "historical relativity" manage to avoid an inherent contradiction.
For example, if one asserts "all truths are relative" (to an historical epoch or weltenschaung, e.g.), must one not also apply that observation to the "truth" that "all truths are relative?" Which means, of course, that the relativist's position is untenable, because it is itself merely relative and, hence, untrue in a trans-historical sense, at least based upon the relatavist's own assertion.
If the only truth that is NOT relative is the relativist's supposed insight, one must ask on what grounds it is exempted. I suppose it might relate to the fact that the relativist stands at the end of Hegelian history, but still, it smacks of inconsistency.
Thank you for your time.
