Unlike, say, the Enlightenment or Romanticism, postmodernism (even as a word) summons up the movement it intends to overturn. In this way, postmodernism might be seen as the delayed germination of an older seed, planted by artists like Marcel Duchamp, during modernism’s high noon of the 1920s and 1930s. (Seen in this light, the start-date that the V&A offers for postmodernism—1970—is quite late.)
Thus, if modernists like Picasso and Cézanne focused on design, hierarchy, mastery, the one-off, then postmodernists, such as Andy Warhol and Willem de Kooning, were concerned with collage, chance, anarchy, repetition. If modernists such as Virginia Woolf relished depth and metaphysics, then postmodernists such as Martin Amis favoured surface and irony. As for composers, modernists like Béla Bartók were hieratic and formalist, and postmodernists, like John Adams, were playful and interested in deconstructing. In other words, modernism preferred connoisseurship, tended to be European and dealt in universals. Postmodernism preferred commodity and America, and embraced as many circumstances as the world contained.
In the beginning, postmodernism was not merely ironical, merely gesture, some kind of clever sham, a hotchpotch for the sake of it. It became these things later in lesser works by lesser artists: Michael Nyman, Takashi Murakami, Tracey Emin and Jonathan Safran Foer. Rather, in the beginning artists, philosophers, linguists, writers and musicians were bound up in a movement of great force that sought to break with the past, and which did so with great energy. A new and radical permissiveness was the result. Postmodernism was a high-energy revolt, an attack, a strategy for destruction. It was a set of critical and rhetorical practices that sought to destabilise the modernist touchstones of identity, historical progress and epistemic certainty.
Above all, it was a way of thinking and making that sought to strip privilege from any one ethos and to deny the consensus of taste. Like all the big ideas, it was an artistic tendency that grew to take on social and political significance. As Ihab Hassan, the Egyptian-American philosopher, has said, there moved through this (our) period “a vast will to un-making, affecting the body politic, the body cognitive, the erotic body, the individual psyche, the entire realm of discourse in the west.”The pendulum swings. Enter the postmodern Tea-Party.
