Beginning in the 1970s, the mission of modernism was extended by the set of styles and philosophies called postmodernism. Postmodernism was even more aggressively relativistic, insisting that there are many perspectives on the world, none of them privileged. It denied even more vehemently the possibility of meaning, knowledge, progress, and shared cultural values. It was more Marxist and far more paranoid, asserting that claims to truth and progress were tactics of political domination which privileged the interests of straight white males.
