In The American Religion, Bloom says that as a religious critic he has tried to follow something uttered by his secular deity, William Blake, that "Everything Possible to be Believed is an Image of Truth." One would need such an aphorism to avoid breaking out into derision at the Mormons, the Christian Scientists, and the fundamentalists. It looks like one of Blake's sillier lines, itself an image of untruth; unless, of course, Blake actually meant that everything possible to be doubted is an image of truth--that every doubtful thought contains a truth. Harold Bloom, aloft on his sublime religion of art, has never been much enamored of doubt. The hint of it at the end of his book gives his writing a new, and decidedly belated, energy.
