Postmodernism (n.) is incredulity toward meta-narratives.
Postmodernism (n.) is modernism in the nascent state... that is, in process of emerging rather than being identifiable as part of an aesthetic creed operating according to agreed ground rules by which artworks could then be judged.
Postmodernism (n.) is not an age, but a mood or better, a state of mind.
Postmodernism (n.) is not modernism at its end but modernism in the nascent state... thus, a work can become modern only if it is first postmodern.
Postmodernism (n.) is that which in the modern invokes the unpresentable in presentation itself, that which refuses the consolation of correct forms, refuses the consensus of taste permitting a common experience of nostalgia for the impossible, and inquires into new presentations not to take pleasure in them, but to better produce the feeling that there is something unpresentable.
Postmodernism (n.) is a celebration of the capability of the signifier itself to create new forms and, indeed, new rules.
