21. _Nordau_. "The word Mysticism describes a state of mind in which the subject imagines that he perceives or divines unknown and inexplicable relations among phenomena, discerns in things hints at mysteries, and regards them as symbols by which a dark power seeks to unveil, or at least to indicate, all sorts of marvels.... It is always connected with strong emotional excitement.... Nearly all our perceptions, ideas, and conceptions are connected more or less closely through the association of ideas. But to make the association of ideas fulfil its function, one more thing must be added--_attention_, which is the faculty to suppress one part of the memory-images and maintain another part." We must select the strongest and most direct images, those directly connected with the afferent nerves; "this Ribot calls adaptation of the whole organism to a predominant idea.... Attention presupposes strength of will. Unrestricted play of association, the result of an exhausted or degenerate brain, gives rise to Mysticism. Since the mystic cannot express his cloudy thoughts in ordinary language, he loves mutually exclusive expressions. Mysticism blurs outlines, and makes the transparent opaque." The Germans have two words for what we call Mysticism--_Mystik_ and _Mysticismus_, the latter being generally dyslogistic. The long chapter in Nordau's _Degeneration_, entitled "Mysticism," treats it throughout as a morbid state. It will be observed that the last sentence quoted flatly contradicts one of the statements copied from Lasson's essay. But Nordau is not attacking religious Mysticism, so much as that unwholesome development of symbolic "science, falsely so called," which has usurped the name in modern France. Those who are interested in Mysticism should certainly study the pathological symptoms which counterfeit mystical states, and from this point of view the essay in _Degeneration_ is valuable. The observations of Nordau and other alienists must lead us to suspect very strongly the following kinds of symbolical representation, whether the symbols are borrowed from the external world, or created by the imagination:--(a) All those which include images of a sexual character. It is unnecessary to illustrate this. The visions of monks and nuns are often, as we might expect, unconsciously tinged with a morbid element of this kind. (b) Those which depend on mere verbal resemblances or other fortuitous correspondences. Nordau shows that the diseased brain is very ready to follow these false trains of association. (c) Those which are connected with the sense of smell, which seems to be morbidly developed in this kind of degeneracy. (d) Those which in any way minister to pride or self-sufficiency. 22. _Harnack_. "Mysticism is rationalism applied to a sphere above reason."
