Postmodernism - root of all modern evil?

From How French "Intellectuals" Ruined The West: Postmodernism and Its Impact Explained by Helen Pluckrose.

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.

It rejected philosophy which valued ethics, reason and clarity with the same accusation. Structuralism, a movement which (often over-confidently) attempted to analyze human culture and psychology according to consistent structures of relationships, came under attack. Marxism, with its understanding of society through class and economic structures was regarded as equally rigid and simplistic. Above all, postmodernists attacked science and its goal of attaining objective knowledge about a reality which exists independently of human perceptions which they saw as merely another form of constructed ideology dominated by bourgeois, western assumptions. Decidedly left-wing, postmodernism had both a nihilistic and a revolutionary ethos which resonated with a post-war, post-empire zeitgeist in the West. As postmodernism continued to develop and diversify, its initially stronger nihilistic deconstructive phase became secondary (but still fundamental) to its revolutionary “identity politics” phase.

It has been a matter of contention whether postmodernism is a reaction against modernity. The modern era is the period of history which saw Renaissance Humanism, the Enlightenment, the Scientific Revolution and the development of liberal values and human rights; the period when Western societies gradually came to value reason and science over faith and superstition as routes to knowledge, and developed a concept of the person as an individual member of the human race deserving of rights and freedoms rather than as part of various collectives subject to rigid hierarchical roles in society.

The Encyclopaedia Britannica says postmodernism “is largely a reaction against the philosophical assumptions and values of the modern period of Western (specifically European) history” whilst the Stanford Encyclopaedia of Philosophy denies this and says “Rather, its differences lie within modernity itself, and postmodernism is a continuation of modern thinking in another mode.” I’d suggest the difference lies in whether we see modernity in terms of what was produced or what was destroyed. If we see the essence of modernity as the development of science and reason as well as humanism and universal liberalism, postmodernists are opposed to it. If we see modernity as the tearing down of structures of power including feudalism, the Church, patriarchy, and Empire, postmodernists are attempting to continue it, but their targets are now science, reason, humanism and liberalism. Consequently, the roots of postmodernism are inherently political and revolutionary, albeit in a destructive or, as they would term it, deconstructive way.

Indeed. The whole piece is worth reading.
