This is the mystic idea, pure and simple; of course there are various grades of it, as there are of the popular one; for no man holds his own creed and nothing more; and it is good for him, in this piecemeal and shortsighted world, that he should not. Were he over-true to his own idea, he would become a fanatic, perhaps a madman. And so the modern evangelical of the Venn and Newton school, to whom mysticism is neology and nehushtan, when he speaks of "spiritual experiences," uses the adjective in its purely mystic sense; while Bernard of Cluny, in his once famous hymn, "Hic breve vivitur," mingles the two conceptions of the unseen world in inextricable confusion. Between these two extreme poles, in fact, we have every variety of thought; and it is good for us that we should have them; for no one man or school of men can grasp the whole truth, and every intermediate modification supplies some link in the great cycle of facts which its neighbours have overlooked. In the minds who have held this belief, that the unseen world is the only real and eternal one, there has generally existed a belief, more or less confused, that the visible world is in some mysterious way a pattern or symbol of the invisible one; that its physical laws are the analogues of the spiritual laws of the eternal world: a belief of which Mr. Vaughan seems to think lightly; though if it be untrue we can hardly see how that metaphoric illustration in which he indulges so freely, and which he often uses in a masterly and graceful way, can be anything but useless trifling. For what is a metaphor or a simile but a mere paralogism--having nothing to do with the matter in hand, and not to be allowed for a moment to influence the reader's judgment, unless there be some real and objective analogy--homology we should call it--between the physical phenomenon from which the symbol is taken, and the spiritual truth which it is meant to illustrate? What divineness, what logical weight, in our Lord's parables, unless He was by them trying to show his hearers that the laws which they saw at work in the lilies of the field, in the most common occupations of men, were but lower manifestations of the laws by which are governed the inmost workings of the human spirit? What triflers, on any other ground, were Socrates and Plato. What triflers, too, Shakespeare and Spenser. Indeed, we should say that it is the belief, conscious or unconscious, of the eternal correlation of the physical and spiritual worlds, which alone constitutes the essence of a poet.
