Much about the same period it became evident that a marked change had passed over certain aspects of thought in "the most enlightened city of the world," and that among the _jeunesse doree_, in particular, there was a strong revulsion against paramount material philosophy; an epoch of transcendental and mystic feeling was, in fact, beginning. Old associations, having transcendental objects, were in course of revival, or were coming into renewed prominence. Martinists, Gnostics, Kabbalists, and a score of orders or fraternities of which we vaguely hear about the period of the French Revolution, began to manifest great activity; periodicals of a mystical tendency--not spiritualistic, not neo-theosophical, but Hermetic, Kabbalistic, and theurgic--were established, and met with success; books which had grievously weighted the shelves of their publishers for something like a quarter of a century were suddenly in demand, and students of distinction on this side of the channel were attracted towards the new centre. The interest was intelligible to professed mystics; the doctrine of transcendentalism has never had but one adversary, which is the density of the intellectual subject, and wherever the subject clarifies, there is idealism in philosophy and mysticism in religion. Moreover, on the part of mystics, especially here in England, the way of that revival had been prepared carefully, and there could be no astonishment that it came, and none, too, that it was accompanied, as it is accompanied almost invariably, by much that does not belong to it in the way of transcendental phenomena. When, therefore, the rumours of Black Magic, diabolism, and the abuse of occult forces began to circulate, there was little difficulty in attributing some foundation to the report.
