I postulate that the function of art and all creative thought is to make us aware of what we know and don't know that we know. You can't tell anybody anything he doesn't know already. Like those folks living on the sea coast in the Middle Ages, watching those ships come in mast-first year after year - then Galileo wises them up and they are ready to burn him as an egghead deviant. But they cool it out over the years and finally have to admit: "It's round, boys, it's round. We knew it all along." Cezanne showed the viewer objects seen from a certain angle in a certain light and they attacked his canvases with umbrellas at the first exhibition. Well, that doesn't happen any more and any child would recognize the objects in a Cezanne canvas. Joyce made readers aware of their own stream of consciousness and was accused of promulgating a cult of unintelligibility.

If the function of art is to make us aware of what we know and don't know we know, the function of the Christian Church and all its metastases has been and still is to keep us in ignorance of what we know.
