God, what a beautiful essay Jeanette Winterson has written here.
Art is a different value system. Like God, it fails us continually. Like God, we have legitimate doubts about its existence but, like God, art leaves us with footprints of beauty. We sense there is more to life than the material world can provide, and art is a clue, an intimation, at its best, a transformation. We don't need to believe in it, but we can experience it. The experience suggests that the monolith of corporate culture is only a partial reality. This is important information, and art provides it.
