Postmodernism presents a threat not only to liberal democracy but to modernity itself. That may sound like a bold or even hyperbolic claim, but the reality is that the cluster of ideas and values at the root of postmodernism have broken the bounds of academia and gained great cultural power in western society. The irrational and identitarian “symptoms” of postmodernism are easily recognizable and much criticized, but the ethos underlying them is not well understood. This is partly because postmodernists rarely explain themselves clearly and partly because of the inherent contradictions and inconsistencies of a way of thought which denies a stable reality or reliable knowledge to exist. However, there are consistent ideas at the root of postmodernism and understanding them is essential if we intend to counter them. They underlie the problems we see today in Social Justice Activism, undermine the credibility of the Left and threaten to return us to an irrational and tribal “pre-modern” culture.
Postmodernism, most simply, is an artistic and philosophical movement which began in France in the 1960s and produced bewildering art and even more bewildering “theory.” It drew on avant-garde and surrealist art and earlier philosophical ideas, particularly those of Nietzsche and Heidegger, for its anti-realism and rejection of the concept of the unified and coherent individual. It reacted against the liberal humanism of the modernist artistic and intellectual movements, which its proponents saw as naïvely universalizing a western, middle-class and male experience.
