The Snake Eats Its Own Tail
Protagoras (490-420 bc): “Man is the measure of all things.”
Such is the fate of all relativistic theories, ancient or modern. They are self-destructive because self-contradictory. When a pragmatist asserts the impossibility of attaining the absolute, when an instrumentalist with his emphasis on change deplores the dogmatism of unchanging truth, or when a Freudian dismisses conscious reasoning as hypocritical rationalization, he means to except his own view. It is absolutely true that we miss the absolute; it is fixed truth that nothing is fixed; it is validly reasoned that reasoning is hypocrisy. Objections to dogmatism are always dogmatic, and relativisms are always asserted absolutely. For this the Man-measure theory must be rejected, and knowledge is shown to be other than perception.
