This article provides, through a discussion of the work of Jacques Derrida, an examination of the philosophical basis of postmodernism. The first section identifies and explains the positive claims of postmodernism, including the key claim that all identities, presences, etc. depend for their existence on something which is absent and different from themselves. The second section further illustrates the positive claims through an analysis of Derrida's "deconstructionist" reading of Plato. The final section raises a number of critical problems for postmodernism: that it confuses aesthetics with metaphysics; that it mistakes assertion for argument in philosophy; that it is guilty of relativism; and that it is self-contradictory.
