The reader is now placed at those points of view whence he can see the new æsthetic tendencies in their true light and their real shape. It will be the task of the following books to demonstrate the pathological character of each one of these tendencies, and to inquire what particular species of degenerate delirium or hysterical psychological process they are related to or identical with.

MYSTICISM.
CHAPTER I.
THE PSYCHOLOGY OF MYSTICISM.
We have already learnt to see in mysticism a principal characteristic of degeneration. It follows so generally in the train of the latter, that there is scarcely a case of degeneration in which it does not appear. To cite authorities for this is about as unnecessary as to adduce proof for the fact that in typhus a rise in the temperature of the body is invariably observed. I will therefore only repeat one remark of Legrain’s:[64] ‘Mystical thoughts are to be laid to the account of the insanity of the degenerate. There are two states in which they are observed—in epilepsy and in hysterical delirium.’ When Federoff,[65] who makes mention of religious delirium and ecstasy as among the accompanying features of an attack of hysteria, puts them down as a peculiarity of women, he commits an error, since they are at least as common in male hysterical and degenerate subjects as in female.
What is really to be understood by this somewhat vague term ‘mysticism’? The word describes a state of mind in which the subject imagines that he perceives or divines unknown and inexplicable relations amongst 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 which he endeavours to guess, though generally in vain. This condition of mind is always connected with strong emotional excitement, which consciousness conceives to be the result of its presentiments, although it is this excitement, on the contrary, which is pre-existent, while the presentiments are caused by it and receive from it their peculiar direction and colour.
All phenomena in the world and in life present themselves in a different light to the mystic from what they do to the sane man. The simplest word uttered before the former appears to him an allusion to something mysteriously occult; in the most commonplace and natural movements he sees hidden signs. All things have for him deep backgrounds; far-reaching shadows are thrown by them over adjacent tracts; they send out wide-spreading roots into remote substrata. Every image that rises up in his mind points with mysterious silence, though with significant look and finger, to other images distinct or shadowy, and induces him to set up relations between ideas, where other people recognise no connection. In consequence of this peculiarity of his mind, the mystic lives as if surrounded by sinister forms, from behind whose masks enigmatic eyes look forth, and whom he contemplates with constant terror, since he is never sure of recognising any shapes among the disguises which press upon him. ‘Things are not what they seem’ is the characteristic expression frequently heard from the mystic. In the history of a ‘degenerate’ in the clinics of Magnan[66] it is written: ‘A child asks drink of him at a public fountain. He finds this unnatural. The child follows him. This fills him with astonishment. Another time he sees a woman sitting on a curb-stone. He asks himself what that could possibly mean.’ In extreme cases this morbid attitude amounts to hallucinations, which, as a rule, affect the hearing; but it can also influence sight and the other senses. When this is so, the mystic does not confine himself to conjectures and guesses at mysteries in and behind phenomena, but hears and sees as real, things which for the sane man are non-existent.
Pathological observation of the insane is content to describe this mental condition, and to determine its occurrence in the hysterical and degenerate. That, however, is not the end of the matter. We also want to know in what manner the degenerate or exhausted brain falls into mysticism. In order to understand the subject, we must refer to some simple facts in the growth of the mind.[67]
Conscious intellection is activity of the gray surface of the brain, a tissue consisting of countless nerve-cells united by nerve-fibres. In this tissue the nerves, both of the external bodily surface and of the internal organs, terminate. When one of these nerves is excited (the nerve of vision by a ray of light, a nerve in the skin by contact, an organic nerve by internal chemical action, etc.), it at once conveys the excitement to the nerve-cell in the cerebral cortex in which it debouches. This cell undergoes in consequence chemical changes, which, in a healthy condition of the organism, are in direct relation to the strength of the stimulus. The nerve-cell, which is immediately affected by the stimulus conveyed to it by the conducting nerve, propagates in its turn the stimulus received to all the neighbouring cells with which it is connected by fibrous processes. The disturbance spreads itself on all sides, like a wave-circle that is caused by any object thrown into water, and subsides gradually exactly as does the wave—more quickly or more slowly, with greater or less diffusion, as the stimulus that caused it has been stronger or weaker.
Every stimulus which reaches a place on the cerebral cortex results in a rush of blood to that spot,[68] by means of which nutriment is conveyed to it. The brain-cells decompose these substances, and transmute the stored-up energy in them into other forms of energy, namely, into ideas and motor impulses.[69] How an idea is formed out of the decomposition of tissues, how a chemical process is metamorphosed into consciousness, nobody knows; but the fact that conscious ideas are connected with the process of decomposition of tissues in the stimulated brain-cells is not a matter of doubt.[70]
In addition to the fundamental property in the nerve-cells of responding to a stimulus produced by chemical action, they have also the capacity of preserving an image of the strength and character of this stimulus. To put it popularly, the cell is able to remember its impressions. If now a new, although it may be a weaker, disturbance reach this cell, it rouses in it an image of similar stimuli which had previously reached it, and this memory-image strengthens the new stimulus, making it more distinct and more intelligible to consciousness. If the cell could not remember, consciousness would be ever incapable of interpreting its impressions, and could never succeed in attaining to a presentation of the outer world. Particular direct stimuli would certainly be perceived, but they would remain without connection or import, since they are by themselves, and without the assistance of earlier impressions, inadequate to lead to knowledge. Memory is therefore the first condition of normal brain activity.
The stimulus which reaches a brain-cell gives rise, as we have seen, to an expansion of this stimulus to the neighbouring cells, to a wave of stimulus proceeding in all directions. And since every stimulus is connected with the rise of conscious presentations, it proves that every stimulus calls a large number of presentations into consciousness, and not only such presentations as are related to the immediate external cause of the stimulation perceived, but also such as are only aroused by the cells that elaborate them happening to lie in the vicinity of that cell, or group of cells, which the external stimulus has immediately reached. The wave of stimulus, like every other wave-motion, is strongest at its inception; it subsides in direct ratio to the widening of its circle, till at last it vanishes into the imperceptible. Corresponding to this, the presentations, having their seat in cells which are in the immediate neighbourhood of those first reached by the stimulus, are the most lively, while those arising from the more distant cells are somewhat less distinct, and this distinctness continues to decrease until consciousness can no longer perceive them—until they, as science expresses it, sink beneath the threshold of consciousness. Each particular stimulus arouses, therefore, not only in the cell to which it was directly led, but also in countless other contiguous and connected cells, the activity which is bound up with presentation. Thus arise simultaneously, or, more accurately, following each other in an immeasurably short interval of time, thousands of impressions of regularly decreasing distinctness; and since unnumbered thousands of external and internal organic stimuli are carried to the brain, so continually thousands of stimulus-waves are coursing through it, crossing and intersecting each other
