The subject of the present work is one which will generally be thought to need some words of explanation, if not of apology. Mysticism is almost everywhere synonymous with what is most visionary in religion and most obscure in speculation. But a history of Mysticism—old visions and old obscurities—who is bold enough to expect a hearing for that? Is the hopeful present, struggling toward clear intelligence, to pause and hear how, some hundreds of years ago, men made themselves elaborately unintelligible? Is our straining after action and achievement to be relaxed while you relate the way in which Mystics reduced themselves to utter inactivity? While we are rejoicing in escape from superstitious twilight, is it well to recall from Limbo the phantasms of forgotten dreamers, and to people our sunshine with ghostly shadows? And since Mysticism is confessedly more or less a mistake, were it not better to point out to us, if you can, a something true and wise, rather than offer us your portrait of an exaggeration and a folly?

Such are some of the questions which it will be natural to ask. The answer is at hand. First of all, Mysticism, though an error, has been associated, for the most part, with a measure of truth so considerable, that its good has greatly outweighed its evil. On this ground alone, its history should be judged of interest. For we grow more hopeful and more charitable as we mark how small a leaven of truth may prove an antidote to error, and how often the genuine fervour of the spirit has all but made good the failures of the intellect.

In the religious history of almost every age and country, we meet with a certain class of minds, impatient of mere ceremonial forms and technical distinctions, who have pleaded the cause of the heart against prescription, and yielded themselves to the most vehement impulses of the soul, in its longing to escape from the sign to the thing signified—from the human to the divine. The story of such an ambition, with its disasters and its glories, will not be deemed, by any thoughtful mind, less worthy of record than the career of a conqueror. Through all the changes of doctrine and the long conflict of creeds, it is interesting to trace the unconscious unity of mystical temperaments in every communion. It can scarcely be without some profit that we essay to gather together and arrange this company of ardent natures; to account for their harmony and their differences, to ascertain the extent of their influence for good and evil, to point out their errors, and to estimate even dreams impossible to cold or meaner spirits.

These Mystics have been men of like passions and in like perplexities with many of ourselves. Within them and without them were temptations, mysteries, aspirations like our own. A change of names, or an interval of time, does not free us from liability to mistakes in their direction, or to worse, it may be, in a direction opposite. To distinguish between the genuine and the spurious in their opinion or their life, is to erect a guide-post on the very road we have ourselves to tread. It is no idle or pedantic curiosity which would try these spirits by their fruits, and see what mischief and what blessing grew out of their misconceptions and their truth. We learn a lesson for ourselves, as we mark how some of these Mystics found God within them after vainly seeking Him without—hearkened happily to that witness for Him which speaks in our conscience, affections, and desires; and, recognising love by love, finally rejoiced in a faith which was rather the life of their heart than the conclusion of their logic. We learn a lesson for ourselves, as we see one class among them forsaking common duties for the feverish exaltation of a romantic saintship, and another persisting in their conceited rejection of the light without, till they have turned into darkness their light within.

But the interest attaching to Mysticism is by no means merely historic. It is active under various forms in our own time. It will certainly play its part in the future. The earlier portion of this work is occupied, it must be confessed, with modes of thought and life extremely remote from anything with which we are now familiar. But only by such inquiry into those bygone speculations could the character and influence of Christian Mysticism be duly estimated, or even accounted for. Those preliminaries once past, the reader will find himself in contact with opinions and events less removed from present experience.

The attempt to exhibit the history of a certain phase of religious life through the irregular medium of fiction, dialogue, and essay, may appear to some a plan too fanciful for so grave a theme. But it must be remembered, that any treatment of such a subject which precluded a genial exercise of the imagination would be necessarily inadequate, and probably unjust. The method adopted appeared also best calculated to afford variety and relief to topics unlikely in themselves to attract general interest. The notes which are appended have been made more copious than was at first designed, in order that no confusion may be possible between fact and fiction, and that every statement of importance might be sustained by its due authority. It is hoped that, in this way, the work may render its service, not only to those who deem secondary information quite sufficient on such subjects, but also to the scholar, who will thus be readily enabled to test for himself my conclusions, and who will possess, in the extracts given, a kind of anthology from the writings of the leading Mystics. To those familiar with such inquiries it may perhaps be scarcely necessary to state that I have in no instance allowed myself to cite as an authority any passage which I have not myself examined, with its context, in the place to which I refer. In the Chronicle of Adolf Arnstein the minimum of invention has been employed, and no historical personage there introduced utters any remark bearing upon Mysticism for which ample warrant cannot be brought forward. Wherever, in the conversations at Ashfield, any material difference of opinion is expressed by the speakers, Atherton may be understood as setting forth what we ourselves deem the truth of the matter. Some passages in these volumes, and the substance of the chapters on Quietism, have made their appearance previously in the pages of one of our quarterly periodicals.

It should be borne in mind that my design does not require of me that I should give an account of all who are anywhere known to have entertained mystical speculation, or given themselves to mystical practice. I have endeavoured to portray and estimate those who have made epochs in the history of Mysticism, those who are fair representatives of its stages or transitions, those whose enthusiasm has been signally benign or notoriously baneful. I have either mentioned by name only, or passed by in silence, the followers or mere imitators of such men, and those Mystics also whose obscure vagaries neither produced any important result nor present any remarkable phænomena. Only by resolute omission on this principle has it been possible to preserve in any measure that historical perspective so essential to the truth of such delineations.

The fact that the ground I traverse lies almost wholly unoccupied, might be pleaded on behalf of my undertaking. The history of Mysticism has been but incidentally touched by English writers. Germany possesses many monographs of unequal value on detached parts of the subject. Only recently has a complete account of Christian Mysticism appeared, at all on a level with the latest results of historical inquiry.[[1]] This laborious compilation presents the dry bones of doctrinal opinion, carefully separated from actual life—a grave defect in any branch of ecclesiastical history, absolutely fatal to intelligibility and readableness in this. If we except the researches of the Germans into their own mediæval Mysticism, it may be truly said that the little done in England has been better done than the much in Germany. The Mysticism of the Neo-Platonists has found a powerful painter in Mr. Kingsley. The Mysticism of Bernard meets with a wise and kindly critic in Sir James Stephen.

If, then, the subject of this book be neither insignificant in itself, nor exhausted by the labours of others, my enterprise at least is not unworthy, however questionable its success.
