Is this not what the Nazis were trying to achieve, this victorious truth, that ends relativism, not through argument and rationality, but war and irrationality? In attempting to destroy the Jews they were not trying to wipe out a people so much as silence a discourse. Hegelian in form, Foucault's dialectic is not ended through peace, armistice, through synthesis; it is ended by storming the breech, sword in hand, foaming at the mouth and with destruction on its lips.
All oppressed discourses have, at their heart, a teleology; a hero will come and crush the proliferation of truth and reinstigate the golden years of determinacy. For St. Paul it was Christ, for the Jews, another messiah, for the Nazis it was a new Charlemagne and for revolutionary Marxists it would be a new Robespierre or Saint-Just.
Is this acceptable. can we have absolutism from relativism?
