Postmodernism is allergic to the idea of certainty, and makes a great deal of theoretical fuss over this rather modest everyday notion. As such, it is in some ways the flip side of fundamentalism . . . Some postmodern thought suspects that all certainty is authoritarian. It is nervous of people who sound passionately committed to what they say. In this, it represents among other things an excessive reaction to fascism and Stalinism. The totalitarian politics of the twentieth century did not only launch an assault on truth in their own time; they also helped to undermine the idea of truth for future generations.
