Postmodernism is a sophisticated set of ideas constructed to account for the failure of Socialism, both ideological and ‘scientific’ in theory and in practice, by changing the values associated with the language and symbolism of realism (truth is objectively knowable by scientific means) and the nature of man (equality, diversity), and morality ( moral relativism).
The same Left that traditionally promoted reason, science, optimism and equality for all – has now switched to themes of anti-reason, anti-science, double standards, and cynicism But why? Because with the failure of socialism it has adopted the strategy of abrahamic and zoroastrian religions which involves reciting blatant falsehoods in by repetition, peer pressure and indoctrination: that multiculturalism and diversity are ‘good’, and that equality of outcome rather than opportunity is desirable and possible, despite the contrary theory and evidence. That norms – morals, ethics, and manners – have no meaning or value. That all cultures are relative except european, which is bad. That men and women are equal, but men are bad.
This ideology, like Marxism, is present largely in liberal arts departments, despite being rejected by STEM and Economics departments where science retains it’s superiority over anti-realism (and where IQ’s are significantly higher.)
Thorough attempts have been made by Heidegger and Rorty in particular, to attempt to create a non-rational language for discussing experience in subjective terms, rather than objective.
However, despite the failure of these intellectual endeavors, ideological Postmodernism has in fact been adopted as the religion of the state, left intellectuals, and liberal arts graduates at all levels.
However, genetic science, neurobiology, anthropology, and economics continue to counter ideological postmodernism with scientific realism with scholars in each field continuing to undermine these attempts to construct a secular religion of anti-scientific irrationality without the burden of mysticism.
The best way to explain postmodernism today, is the philosophical equivalent of christianity as was used against Roman pragmatism: the promise of magic to motivate the masses.
