The imagination, when thus employed to anticipate or correct the conclusions of the understanding, is of course not called imagination by those, who appeal to it. The religious teachers call it prophecy or revelation, the philosophers call it a higher reason. But these names are merely eulogistic synonyms for imagination, implying (what is perfectly possible) that the imagination has not misled us. They imply on the contrary that in the given instances the imagination has hit upon an ultimate truth. A prophet, unless he be the merely mechanical vehicle of truths he does not understand, cannot be conceived as anything but a man of imagination, whose visions miraculously mirror the truth. A metaphysician who transcends the intellect by his reason can be conceived only as using his imagination to such good purpose as to divine by it the ideal laws of reality or the ultimate goals of moral effort. His reason is an imagination that succeeds, an intuition that guesses the principle of experience. But if this intuition were of such a nature that experience could verify it, then that higher reason or imagination would be brought down to the level of the understanding; for understanding, as we have defined it, is itself a kind of imagination, an imagination prophetic of experience, a spontaneity of thought by which the science of perception is turned into the art of life. The same absence of verification distinguishes revelation from science; for when the prophecies of faith are verified, the function of faith is gone. Faith and the higher reason of the metaphysicians are therefore forms of imagination believed to be avenues to truth, as dreams or oracles may sometimes be truthful, not because their necessary correspondence to truth can be demonstrated, for then they would be portions of science, but because a man dwelling on those intuitions is conscious of a certain moral transformation, of a certain warmth and energy of life. This emotion, heightening his ideas and giving them power over his will, he calls faith or high philosophy, and under its dominion he is able to face his destiny with enthusiasm, or at least with composure.
