The idea of a philosophical absolutism is rightly repugnant to many people since it is, as a rule, combined with a dogmatic and authoritarian claim to possess the truth, or a criterion of truth.
But there is another form of absolutism—a fallibilistic absolutism—which indeed rejects all this: it merely asserts that our mistakes, at least, are absolute mistakes, in the sense that if a theory deviates from the truth, it is simply false, even if the mistake made was less glaring than that in another theory. Thus the notions of truth, and of falling short of the truth, can represent absolute standards for the fallibilist. This kind of absolutism is completely free from any taint of authoritarianism.
