What is PoMo? Postmodernism, Postmodernity, PostModern Philosophy
The instability of your question leaves me with several contradictorily layered responses whose interconnectivity cannot express the logocentric coherency you seek.

(SOURCE: Hassan "The Culture of Postmodernism" Theory, Culture, and Society, V 2 1985, 123-4.) PostModern Philosophy is practically the game of negating all the philosophies which originated before it (classical, romantic, modern). This movement began through Nietzche, Kant, Hegel, and Heidegger, who implanted the ideas of the separation between the āIā and that which exists. All becomes perception and everything is a mis-reading. Major Players
