Rorty begins this chapter by addressing critics who accuse him of irrationality and moral relativism. He asserts that accusations of irrationality are merely affirmations of vernacular "otherness". We use the term "irrational" when we come across a vocabulary that cannot be synthesized with our own, as when a father calls his son irrational for being scared of the dark, or when a son calls his father irrational for not checking under the bed for monsters. The vocabulary of "real monsters" is not shared between father and son, and so accusations of irrationality fly. As for moral relativism, for Rorty, this accusation can only be considered a criticism if one believes in a metaphysically salient and salutary moral, which Rorty firmly does not.
