In response to the links, which I admit I haven't yet fully read, I can still speculate that taken literally, "post-modern" means something that is occuring after now. Physically, that is impossible. If that something is indeed occuring, it is then in the "now" and is therefore modern. We could have no conception as to what post modern is, simply because it hasn't occured yet. If one was to say of a post modern idea, unless that someone doesn't really know what the idea is, he is still brandishing the idea. As "soliloquy" has pointed out, something can be called "post modern" if it is viewed from past, and only if that past is still in the notion of being modern. Obviously, we have a contradiction. Past cannot ever be modern, and modern can never be post modern.
