THE ordinary fields of psychological inquiry, largely in possession of the pathologist, are fringed by a borderland of occult and dubious experiment into which pathologists may occasionally venture, but it is left for the most part to unchartered explorers. Beyond these fields and this borderland there lies the legendary wonder-world of Theurgy, so called, of Magic and Sorcery, a world of fascination or terror, as the mind which regards it is tempered, but in either case the antithesis of admitted possibility. There all paradoxes seem to obtain actually, contradictions coexist logically, the effect is greater than the cause and the shadow more than the substance. Therein the visible melts into the unseen, the invisible is manifested openly, motion from place to place is accomplished without traversing the intervening distance, matter passes through matter. There two straight lines may enclose a space; space has a fourth dimension, and untrodden fields beyond it; without metaphor and without evasion, the circle is mathematically squared. There life is prolonged, youth renewed, physical immortality secured. There earth becomes gold, and gold earth. There words and wishes possess creative power, thoughts are things, desire realises its object. There, also, the dead live and the hierarchies of extra-mundane intelligence are within easy communication, and become ministers or tormentors, guides or destroyers, of man. There the Law of Continuity is suspended by the interference of the higher Law of Fantasia.
But, unhappily, this domain of enchantment is in all respects comparable to the gold of Faerie, which is presumably its medium of exchange. It cannot withstand daylight, the test of the human eye, or the scale of reason. When these are applied, its paradox becomes an anticlimax, its antithesis ludicrous; its contradictions are without genius; its mathematical marvels end in a verbal quibble; its elixirs fail even as purges; its transmutations do not need exposure at the assayer's hands; its marvel-working words prove barbarous mutilations of dead languages, and are impotent from the moment that they are understood; departed friends, and even planetary intelligences, must not be seized by the skirts, for they are apt to desert their draperies, and these are not like the mantle of Elijah.
