In the pursuit of mysticism there are often several painful facts to record. In the first place, it is common to find a mystical temperament in those whose physical nature is not very strong or passionate. It seems as if certain natures, by the very fact that the ties which hold them to the earth are more than half-loosened already, have a strong affinity to the world of abstractions--as if the very weakness of their corporeal organisation held open a door through which strange shapes are seen moving, and airy voices heard to call; and again the mystical life is, more than any other, subject to deep depressions of spirit, dumb insensibilities, and heavy overshadowings from the towers of death. In the history of More's life no trace of either of these failings can be even faintly discovered. In the first place, he was of a strong and sound constitution; he did not know what it was to be languid or out of health; he was gifted with an extraordinary spring and plenty of pure animal spirits--"a rich ethereal sort of body, for what was inward," to use his own Pythagorean phrase; he says of himself that his body seemed built for a hundred years; that he had a high warmth and activity of thought that never flagged--notably too, that, after a long day of incessant thought, when he came to sleep he had a strange sort of narcotic power; and he was no sooner in a manner laid on his bed, that the falling of a house would scarce wake him, and that he woke in the morning to an inexpressible life and vigour, so that his thoughts and notions "rayed" about him. There would seem to be little of the visionary here; and yet he confesses to a consciousness of what he calls "Enthusiasm"--which we should almost call madness: he could summon up a material object with such distinctness--visualise it, as it is now called--that it produced on him all the sensations of being seen with the outward eye: that is, he could at any moment, with his eyes open, command a scene or a person, so that the vision passed before and effaced the furniture of his room or the page of his book: and he says that all his life he could, with an almost inconsiderable effort of the will, fix his mind so intently on any subject or line of thought that he could spend as much as three hours in an intent uninterrupted reverie.
