The distinguishing characteristic of postmodernist theorizing is its rejection of traditional philosophy and metaphysics. The Western philosophical tradition itself is, of course, a record of debate rather than consensus. The postmodernists, however, claim to have rejected not one thesis or another but rather the entire philosophical tradition from Plato through George Santayana. Deconstructionists, pragmatists and New Historicists certainly make assertions and criticize opposing views, just as traditional thinkers did. Unlike traditional philosophers, however, postmodernists make no attempt to tell the truth about reality. They realize, what in their view their predecessors failed to grasp, that human reason is an inadequate instrument for achieving truth. They have therefore renounced metaphysics and philosophy in favor of what Carl Rapp calls "post-rational criticism."
