The purpose of the article is to (a) show and briefly explain the socio-historical conditions that gave rise to postmodernism as a discipline in the humanities, a discipline that was to become the biggest rival of Marxian sociology (i.e., materialist conception of history and class analysis) in the era of neoliberalism, which took hold at the end of 1970s; (b) to show why the postmodernist critique of such sociology is unwarranted; (c) to outline theoretical as well as political implications of the postmodernist turn and the marginalization of Marxian sociology. The conclusion is that the turn towards postmodernism is unnecessary and, in fact, regressive because of its unfounded marginalization of Marxian sociology.
