You seem to identify postmodernism with relativism (just one of several postmodern paths). I maintain that it is postmodernism to accept a single truth, or to accept many truths, philosophically; the postmodernism is to say that we can only know those truths subjectively. Knowledge can be revealed, and more knowledge can be revealed later. This knowledge is not objective, but is subjective—mediated and conditioned. Nevertheless, since all our knowledge is subjective, this per se should not prejudice us. Not all subjective knowledge is equal. My knowledge that my wife likes Cadbury’s chocolate may be subjective, conditioned, mediated, and socially constructed—yet it remains real knowledge. What I have yet to learn about my wife may be a number of possibilities, but other possibilities are excluded.
