worlds far removed from the actual which are yet living and very near to the heart. Such is the fruit of abstraction when abstraction bears any fruit. If the imagination merely alienates us from reality, without giving us either a model for its correction or a glimpse into its structure, it becomes the refuge of poetical selfishness. Such selfishness is barren, and the fancy, feeding only on itself, grows leaner every day. Mysticism is usually an incurable disease. Facts cannot arouse it, since it never denied them. Reason cannot convince it, for reason is a human faculty, assuming a validity which it cannot prove. The only thing that can kill mysticism is its own uninterrupted progress, by which it gradually devours every function of the soul and at last, by destroying its own natural basis, immolates itself to its inexorable ideal.

Need we ask, after all these reflections, where we should look for that expansion and elevation of the mind which the mystic seeks so passionately and so unintelligently? We can find that expansion, in the first place, in the imagination itself. That is the true realm of man's infinity, where novelty may exist without falsity and perpetual diversity without contradiction. But such exercise of imagination leaves the world of knowledge untouched. Is there no escape from the prison, as the mystic thinks it, of science and history which shall yet not carry us beyond reality? Is there no truth beyond conventional truth, no life behind human existence?

Certainly. Behind the discovered there is the discoverable, beyond the actual, the possible. Science and history are not exhausted. In their determinate directions they are as infinite as fancy in its indetermination. The spectacle which science and history now spread before us is as far beyond the experience of an ephemeral insect as any Absolute can be beyond our own; yet we have put that spectacle together out of just such sensations as the insect may have—out of this sunlight and this buzz and these momentary throbs of existence. The understanding has indeed supervened, but it has supervened not to deny the validity of those sensations, but to combine their messages. We may still continue in the same path, by the indefinite extension of science over a world of experience and of intelligible truth. Is that prospect insufficient for our ambition? With a world so full of stuff before him, I can hardly conceive what morbid instinct can tempt a man to look elsewhere for wider vistas, unless it be unwillingness to endure the sadness and the discipline of the truth.

But can our situation be made better by refusing to understand it? If we
