Post-modernism itself isn’t easy to grasp, as it has so many variations and applications, but it works on the concept of deconstructionism (a la “this is not a pipe”, see http://en.wikipedia.org/wiki/Ren%C3%A9_Magritte). Or, maybe in the modern sense of the word “fact” would mean “absolute” (“facts are simple and facts are straight”) where a post-modernist would say facts are determined by the decentralized interpretation.

I’m a fan of the Talking Heads who put it this way:

Facts are simple and facts are straight
Facts are lazy and facts are late
Facts all come with points of view
Facts don’t do what I want them to
Facts just twist the truth around
Facts are living turned inside out
Facts are getting the best of them
Facts are nothing on the face of things
Facts don’t stain the furniture
Facts go out and slam the door
Facts are written all over your face
Facts continue to change their shape
(from “Crosseyed and Painless”)

In the case of religion, interpretation (in this case, faith) and action (in this case, practice) takes precedence over the authority and emphasis on belief. Hence it’s application to Quakerism in the modern world where faith and practice create a basis for a post-modern Quaker.

I’m completely oversimplifying here, for the sake of brevity, and am in no way truly versed in philosophy, but am summarizing and smashing atoms together here to try and capture the point.
