How can one claim that any of the following theories themselves are true, when by their
own assertions truth is merely the cognitive product of the comprehensively explaining-determining factors that those theories specify?
Is belief that naturalism is true itself completely determined by natural causes and laws, merely the function of our adjustment as organisms to our environment? If physical matter is the only reality, how can materialism itself be true, in addition to being merely a physical object? Is relativism itself relative? Is subjectivism itself subjective? Is Marxism itself merely an economically determined set of brain actions? Is behaviorism itself merely an observable and quantifiable behavioral event? Is psychologism itself merely the product of psychological factors? Is skepticism itself as uncertain and unknowable as all the other items of possible knowledge it denies? Does empiricism itself have any empirical evidence or sense experience that justifies believing it? Is existentialism itself unexplainable and absurd? Is idealism itself a mere mental construct about alleged objects of external perception? Is logical positivism itself meaningless because it can't be logically analyzed into elementary tautologies or empirically verifiable statements? Is pragmatism itself true, or merely practical? Is there a reason why rationalism excludes empirical factors in knowing? Is utilitarianism itself merely an attempt to be happy, and not even a theory?

Everything postmodern I've read seems to just be generic old fixed-factor reductionism, the same as Marxism, Behaviorism, Materialism, Contextualism, and so on. Pick your favorite universally determining factors and away we go, spawning universal explanatory reductionisms, arbitrating the existence, nature, and status of what's real, and so on.
Postmodern rhetoric is good for 1) logical analysis, 2) defense attorneys, 3) sociopaths and others into hoodwinking people in various senses, and 4) students who want to rhetorically hoax their way through a substantial number of school courses with writing requirements. Viva Joey Skaggs! [Look up "Sokel Hoax" to see what I mean]
But postmodernism in general makes it much easier when I'm lobbying rich alumni to close down those useless and meaningless wastes of money called philosophy departments---as an expression of their nihilism. Others can play the nihilism game too---but in this case by redirecting the money that's normally used to prop up people who insult the views of those funding them.
