I'm using the phrase "postmodern critique" as a shorthand for the general critique of modernism of such postmodern philosophers as Nietzsche, Foucault, Derrida, et. al. I did so in the same way that PatrickHenry referenced 'objectivism' without providing a complete description of the philosophy. A google search of 'postmodernism' or 'Foucault' would turn up plenty of material, I would imagine.
