Re: Check out Jordan B. Peterson
But, ya know, it's all about post-modernists.
Post-modernism can be as readily dismissed as can be Jungian psychology. There hasn't been any advance in post-modernism for 30 years. No new Derrida carrying the flag, nothing like that. I don't expect that Peterson holds much of a positive opinion about Jungian ideas, given its lack of a scientific basis. Both are dead in the water.
So why does Peterson attack post-modernism? Because it's an easy target and it carries associations. He uses it as an inroad to undermine his perception of socialism, due to his pre-existing ideas on the subject (no wonder he's so popular with the alt-right). Just as in the way you've inserted Marxists alongside post-modernism; you might have failed to notice that one school significantly pre-dates the other and that neither is dependant upon the other. This is why I originally said that a person's consumption of Peterson's verbiage can give an insight into the way that person's mind works. I'd like to think that, what with him being a psychologist, Peterson would appreciate that.
BTW, while I will happily state that my politics lean mostly leftwards I don't describe myself as a socialist, nor do I think anyone else with a reasonable understanding of the term could describe me as one either. I just say that so that no-one need bother with any replies beginning "Well your pre-existing ideas..." Because obviously I'd prefer replies which examine my id, ego and anima, or which deconstruct fundamental human perceptions of the universe, or which critique me on the basis of Marxist dialectic.
