Did Political Correctness Kill David Foster Wallace?

Glancing over Lev Grossman's review of Wallace's heavily edited new book, “The Pale King,” I was struck with the idea that if Wallace had been allowed to understand and write about real human nature, for example, as defined by sociobiology, such things as the importance of the biological origin of much of social behavior, human differences, hierarchy, evolution, even future eugenics, rather than following the hollow path of postmodernism, it might have offered a real foundation for Wallace's troubled mind.

Postmodernism is what is left when political correctness decides the subjects. It seems to go back to the phenomenologists and existentialists who decided that man is trapped in his own ego, where only subjective truth is possible, unless you go through philosophical contortions to try to prove parallel egos working, subjectively, together. Heidegger wrote brilliant and deep philosophy, but he must have known that he would be crucified if he wrote about true human nature---attempts have been made to try to destroy him anyway, motivated, it seems, by the fact that Heidegger held a job during the Hitler madness.

With this postmodern foundation, of lack of foundation, it is no wonder that writers like Wallace wrote plot-less, but poetically brilliant books. Postmodernism and existentialism instigated a phony, politically correct death to art and culture. I think it was this that helped to drive an already unstable Wallace to kill himself.
