This modern mysticism is very much entangled with theories about the cure of bodily disease by suggestion; and it is fair to warn those who are unacquainted with the books of this sect that they will find much fantastic superstition mixed with a stimulating faith in the inner light as the voice of God. But whatever may be the course of this particular movement there can be no doubt that the Americans, like ourselves, are only at the beginning of a great revival of mystical religion. The movement will probably follow the same course as the mediaeval movement in Germany, with which this little book is concerned. It will have its philosophical supportees, who will press their speculation to the verge of Pantheism, perhaps reviving the Logos-cosmology of the Christian Alexandrians under the form of the pan-psychism of Lotze and Fechner. It will have its evangelists like Tauler, who will carry to our crowded town populations the glad tidings that the kingdom of God is not here or there, but within the hearts of all who will seek for it within them. It will assuredly attract some to a life of solitary contemplation; while others, intellectually weaker or less serious, will follow the various theosophical and theurgical delusions which, from the days of Iamblichus downward, have dogged the heels of mysticism. For the "False Light" against which the "Theologia Germanica" warns us is as dangerous as ever; we may even live to see some new "Brethren of the Free Spirit" turning their liberty into a cloak of licentiousness. If so, the world will soon whistle back the disciplinarian with his traditions of the elders; prophesying will once more be suppressed and discredited, and a new crystallising process will begin. But before that time comes some changes may possibly take place in the external proportions of Christian orthodoxy. The appearance of a vigorous body of faith, standing firmly on its own feet, may even have the effect of relegating to the sphere of pious opinion some tenets which have hitherto "seemed to be pillars." For these periodical returns to the "fresh springs" of religion never leave the tradition exactly where it was before. The German movement of the fourteenth century made the Reformation inevitable, and our own age may be inaugurating a change no less momentous, which will restore in the twentieth century some of the features of Apostolic Christianity.
