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 with the greatest diversity, and in their course arousing millions of emerging, waning, and vanishing impressions. It is this that Goethe means when he depicts in such splendid language how

‘...ein Tritt tausend FÄden regt,
Die Schifflein herÜber, hinÜber schiessen,
Die FÄden ungesehen fliessen,
Ein Schlag tausend Verbindungen schlÄgt.’[71]

Now, memory is a property not only of the nerve-cell, but also of the nerve-fibre, which is only a modification of the cell. The fibre has a recollection of the stimulus which it conveyed, in the same way as the cell has of that which it has transformed into presentation and motion. A stimulus will be more easily conducted by a fibre which has already conveyed it, than by one which propagates it for the first time from one cell to another. Every stimulus which reaches a cell will take the line of least resistance, and this will be set out for it along those nerve-tracks which it has already traversed. Thus a definite path is formed for the course of a stimulus-wave, a customary line of march; it is always the same nerve-cells which exchange mutually their stimulus-waves. Presentation always awakens the same resulting presentations, and always appears in consciousness accompanied by them. This procedure is called the association of ideas.

It is neither volition nor accident that determines to which other cells a disturbed cell habitually communicates its stimulus, which accompanying impressions an aroused presentation draws with it into consciousness. On the contrary, the linking of presentations is dependent upon laws which Wundt especially has well formulated.

Those who have not been born blind and deaf (like the unfortunate Laura Bridgman, cited by all psychologists) will never be influenced by one external stimulus only, but invariably by many stimuli at once. Every single phenomenon of the outer world has, as a rule, not only one quality, but many; and since that which we call a quality is the assumed cause of a definite sensation, it results that phenomena appeal at once to several senses, are simultaneously seen, heard, felt, and moreover are seen in different degrees of light and colour, heard in various nuances of timbre, etc. The few phenomena which possess only one quality and arouse therefore only one sense, e.g., thunder, which is only heard, although with varying intensity, occur nevertheless in conjunction with other phenomena, such as, to keep to thunder, with a clouded sky, lightning and rain. Our brains are therefore accustomed to receive at once from every phenomenon several stimuli, which proceed partly from the many qualities of the phenomenon itself, and partly from the phenomena usually accompanying it. Now, it is sufficient that only one of these stimuli should reach the brain, in order to call into life, in virtue of the habitual association of the memory-images, the remaining stimuli of the same group as well. Simultaneity of impressions is therefore a cause of the association of ideas.

One and the same quality belongs to many phenomena. There is a whole series of things which are blue, round, and smooth. The possession of a common quality is a condition of similarity, which is greater in proportion to the number of common qualities. Every single quality, however, belongs to a habitually associated group of qualities, and can by the mechanism of simultaneity arouse the memory-image of this group. In consequence of their similarity, therefore, the memory-images can be aroused of all those groups, which resemble each other in some quality. The colour blue is a quality which belongs equally to the cheerful sky, the cornflower, the sea, certain eyes, and many military uniforms. The perception of blue will awaken the memory of some or many blue things which are only related through their common colour. Similarity is therefore another cause of the association of ideas.

It is a distinctive characteristic of the brain-cell to elaborate at the same time both a presentation and its opposite. It is probable that what we perceive as its opposite is generally, in its original and simplest form, only the consciousness of the cessation of a certain presentation. As the fatigue of the optic nerve by a colour arouses the sensation of the complimentary colour, so, on the exhaustion of a brain-cell through the elaboration of a presentation, the contrary presentation appears in consciousness. Now, whether this interpretation be right or not, the fact itself is established through the ‘contradictory double meaning of primitive roots,’ discovered by K. Abel.[72] Contrast is the third cause of the association of ideas.

Many phenomena present themselves in the same place close to, or after, one another; and we associate there, presentation of the particular place with those objects, to which it is used to serve as a frame. Simultaneity, similarity, contrast, and occurrence in the same place (contiguity), are thus, according to Wundt, the four conditions under which phenomena will be connected in our consciousness through the association of ideas. To these James Sully[73] believes yet a fifth should be added: presentations which are rooted in the same emotion. Nevertheless all the examples cited by the distinguished English psychologist demonstrate without effort the action of one or more of Wundt’s laws.

In order that an organism should maintain itself, it must be in a position to make use of natural resources, and protect itself from adverse conditions of every sort. It can accomplish this only if it possesses a knowledge of these adverse conditions, and of such natural resources as it can use; and it can do this better and more surely the more complete this knowledge is. In the more highly differentiated organism it devolves upon the brain and nervous system to acquire knowledge of the outer world, and to turn that knowledge to the advantage of the organism. Memory makes it possible for the brain to perform its task, and the mechanism by which memory is made to serve the purport of knowledge is the association of ideas. For it is clear that a brain, in which a single perception awakens through the operation of the association of ideas a whole train of connected representations, will recognise, conceive and judge far more rapidly than one in which no association of ideas obtains, and which therefore would form only such concepts as had for their content direct sense-perceptions and such representations as originated in those cells which, by the accident of their contiguity, happened to lie in the circuit of a stimulus-wave. For the brain which works with association of ideas, the perception of a ray of light, of a tone, is sufficient, in order instantly to produce the presentation of the object from which the sensation proceeds, as well as of its relations in time and space, to group these presentations as concepts, and from these concepts to arrive at a judgment. To the brain without association of ideas that perception would only convey the presentation of having something bright or sonant in front of it. In addition, presentations would be aroused which had nothing in common with this bright or sonant something; it could form no image of the exciter of the sense, but it would first have to receive a train of further impressions from several or all of the senses, in order to learn to recognise the various properties of the object, of which at first only a tone or a colour was perceived, and to unite them in a single presentation. Even then the brain would only know in what the object consisted, i.e., what it had in front of it, but not how the object stood in relation to other things, where and when it had already been perceived, and by what phenomena it was accompanied, etc. Knowledge of objects thus acquired would be wholly unadapted to the formation of a right judgment. It can now be seen what a great advantage was given to the organism in the struggle for existence by the association of ideas, and what immense progress in the development of the brain and its activity the acquirement of it signified.

But this is only true with a limitation. The association of ideas as such does not do more to lighten the task of the brain in apprehending and in judging than does the uprising throng of memory-images in the neighbourhood of the excited centre. The presentations, which the association of ideas calls into consciousness, stand, it is true, in somewhat closer connection with the phenomenon which has sent a stimulus to the brain, and by the latter has been perceived, than do those occurring in the geometrical circuit of the stimulus-wave; but even this connection is so slight, that it offers no efficient help in the interpretation of the phenomenon. We must not forget that properly all our perceptions, ideas, and conceptions are connected more or less closely through the association of ideas. As in the example cited above the sensation of blue arouses the ideas of the sky, the sea, a blue eye, a uniform, etc., so will each of these ideas arouse in its turn, according to Wundt’s law, ideas associated with them. The sky will arouse the idea of stars, clouds and rain; the sea, that of ships, voyages, foreign lands, fishes, pearls, etc.; blue eyes, that of a girl’s face, of love and all its emotions; in short, this one sensation, through the mechanism of the association of ideas, can arouse pretty well almost all the conceptions which we have ever at any time formed, and the blue object which we have in fact before our eyes and perceive, will, through this crowd of ideas which are not directly related to it, be neither interpreted nor explained.

In order, however, that the association of ideas may fulfil its functions in the operations of the brain, and prove itself a useful acquisition to the organism, one thing more must be added, namely, attention. This it is which brings order into the chaos of representations awakened by the association of ideas, and makes them subserve the purposes of cognition and judgment.

What is attention? Th. Ribot[74] defines this attribute as ‘a spontaneous or an artificial adaptation of the individual to a predominating thought’. (I translate this definition freely because too long an explanation would be necessary to make the uninitiated comprehend the expressions made use of by Ribot.) In other words, attention is the faculty of the brain to suppress one part of the memory-images which, at each excitation of a cell or group of cells, have arisen in consciousness, by way either of association or of stimulus-wave; and to maintain another part, namely, only those memory-images which relate to the exciting cause, i.e., to the object just perceived.

Who makes this selection among the memory-images? The stimulus itself, which rouses the brain-cells into activity. Naturally those cells would be the most strongly excited which are directly connected with the afferent nerves. Somewhat weaker is the excitement of the cells to which the cell first excited sends its impulse by way of the customary nerve channels; still weaker the excitement of those cells which, by the same mechanism, receive their stimulus from the secondarily excited cell. That idea will be the most powerful, therefore, which is awakened directly by the perception itself; somewhat weaker that which is aroused by the first impression through association of ideas; weaker still that which the association in its turn involves. We know further that a phenomenon never produces a single stimulus, but several at once. If, for example, we see a man before us, we do not merely perceive a single point in him, but a larger or smaller portion of his exterior, i.e., a large number of differently coloured and differently illuminated points; perhaps we hear him as well, possibly touch him, and, at all events, perceive besides him somewhat of his environment, of his spacial relations. Thus, there arise in our brain quite a number of centres of stimulation, operating simultaneously in the manner described above. There awakes in consciousness a series of primary presentations, which are stronger, i.e., clearer, than the associated or consequent representations, namely, just those presentations which the man standing before us has himself aroused. They are like the brightest light-spots in the midst of others less brilliant. These brightest light-spots necessarily predominate in consciousness over the lesser ones. They fill the consciousness, which combines them in a judgment. For what we call a judgment is, in the last resort, nothing else than a simultaneous lighting up of a number of presentations in consciousness, which we in truth only bring into relation with each other because we ourselves became conscious of them at one and the same moment. The ascendency which the clearer presentations acquire over the more obscure, the primary presentations over derived representations, in consciousness, enables them, with the help of the will, to influence for a time the whole brain-activity to their own advantage, viz., to suppress the weaker, i.e., the derived, representations; to combat those which cannot be made to agree with them; to reinforce, to draw into their circuit of stimulation, or simply to arouse, others, through which they themselves are reinforced and secure some duration in the midst of the constant emergence and disappearance of representations in their pursuit of each other. I myself conceive the interference of the will in this struggle for life amongst representations as giving motor impulses (even if unconsciously) to the muscles of the cerebral arteries. By this means the bloodvessels are dilated or contracted as required,[75] and the consequent supply of blood becomes more or less copious.[76] The cells which receive no blood must suspend their action; those which receive a larger supply can, on the contrary, operate more powerfully. The will which regulates the distribution of blood, when incited by a group of presentations temporarily predominating, thus resembles a servant who is constantly occupied in a room in carrying out the behests of his master: to light the gas in one place, in another to turn it up higher, in another to turn it off partly or wholly, so that at one moment this, and at another that, corner of the room becomes bright, dim, or dark. The preponderance of a group of presentations allows them during their period of power to bring into their service, not only the brain-cells, but the whole organism besides; and not only to fortify themselves through the representations which they arouse by way of association, but also to seek certain new sense-impressions, and repress others, in order, on the one hand, to obtain new excitations favourable to their persistence—new original perceptions—and on the other hand, through the exclusion of the rest, to ward off such excitations as are adverse to their persistence.

For instance, I see in the street a passer-by who for some reason arouses my attention. The attention immediately suppresses all other presentations which, an instant before, were in my consciousness, and permits those only to remain which refer to the passer-by. In order to intensify these presentations I look after him, i.e., the ciliary and ocular muscles, then the muscles of the neck, perhaps also the muscles of the body and of the legs, receive motor impulses, which serve the purpose only of keeping up continually new sense-impressions of the object of my attention, by means of which the presentations of him are continuously strengthened and multiplied. I do not notice other persons who for the time come into my field of vision, I disregard the sounds which meet my ears, if my attention is strong enough I do not perhaps even hear them; but I should at once hear them if they proceeded from the particular passer-by, or if they had any reference to him.

This is the ‘adaptation of the whole organism to a predominant idea’ of which Ribot speaks. This it is which gives us exact knowledge of the external world. Without it that knowledge would be much more difficult of attainment, and would remain much more incomplete. This adaptation will continue until the cells, which are the bearers of the predominating presentations, become fatigued. They will then be compelled to surrender their supremacy to other groups of cells, whereupon the latter will obtain the power to adapt the organism to their purposes.

Thus we see it is only through attention that the faculty of association becomes a property advantageous to the organism, and attention is nothing but the faculty of the will to determine the emergence, degree of clearness, duration and extinction of presentations in consciousness. The stronger the will, so much the more completely can we adapt the whole organism to a given presentation, so much the more can we obtain sense impressions which serve to enhance this presentation, so much the more can we by association induce memory-images, which complete and rectify the presentation, so much the more definitely can we suppress the presentations which disturb it or are foreign to it; in a word, so much the more exhaustive and correct will our knowledge be of phenomena and their true connection.

Culture and command over the powers of nature are solely the result of attention; all errors, all superstition, the consequence of defective attention. False ideas of the connection between phenomena arise through defective observation of them, and will be rectified by a more exact observation. Now, to observe means nothing else than to convey deliberately determined sense-impressions to the brain, and thereby raise a group of presentations to such clearness and intensity that it can acquire preponderance in consciousness, arouse through association its allied memory-images, and suppress such as are incompatible with itself. Observation, which lies at the root of all progress, is thus the adaptation through attention of the sense-organs and their centres of perception to a presentation or group of presentations predominating in consciousness.

A state of attention allows no obscurity to persist in consciousness. For either the will strengthens every rising presentation to full clearness and distinctness, or, if it cannot do this, it extinguishes the idea completely. The consciousness of a healthy, strong-minded, and consequently attentive man, resembles a room in the full light of day, in which the eye sees all objects distinctly, in which all outlines are sharp, and wherein no indefinite shadows are floating.

Attention, therefore, presupposes strength of will, and this, again, is the property only of a normally constituted and unexhausted brain. In the degenerate, whose brain and nervous system are characterized by hereditary malformations or irregularities; in the hysterical, whom we have learnt to regard as victims of exhaustion, the will is entirely lacking, is possessed only in a small degree. The consequence of weakness or want of will is incapacity of attention. Alexander Starr[77] published twenty-three cases of lesions, or diseases of the convolutions of the brain, in which ‘it was impossible for the patients to fix their attention’; and Ribot[78] remarks: ‘A man who is tired after a long walk, a convalescent who has undergone a severe illness—in a word, all weakened persons are incapable of attention.... Inability to be attentive accompanies all forms of exhaustion.’

Untended and unrestrained by attention, the brain activity of the degenerate and hysterical is capricious, and without aim or purpose. Through the unrestricted play of association representations are called into consciousness, and are free to run riot there. They are aroused and extinguished automatically; and the will does not interfere to strengthen or to suppress them. Representations mutually alien or mutually exclusive appear continuously. The fact that they are retained in consciousness simultaneously, and at about the same intensity, combines them (in conformity with the laws of conscious activity) into a thought which is necessarily absurd, and cannot express the true relations of phenomena.

Weakness or want of attention, produces, then, in the first place, false judgments respecting the objective universe, respecting the qualities of things and their relations to each other. Consciousness acquires a distorted and blurred view of the external world. And there follows a further consequence. The chaotic course of stimuli along the channels of association and of the adjacent structures arouses the activity both of contiguous, of further, and of furthest removed groups of cells, which, left to themselves, act only so long and with such varying intensity as is proportionate to the intensity of the stimulus which has reached them. Clear, obscure, and yet obscurer representations rise in consciousness, which, after a time, disappear again, without having attained to greater distinctness than they had when first appearing. The clear representations produce a thought, but such a one as cannot for a moment become firmer or clearer, because the definite representations of which it is composed are mingled with others which consciousness perceives indistinctly, or scarcely perceives at all. Such obscure ideas cross the threshold of even a healthy person’s consciousness; but in that case attention intervenes at once, to bring them fully to the light, or entirely to suppress them. These synchronous overtones of every thought cannot, therefore, blur the tonic note. The emergent thought-phantoms can acquire no influence over the thought-procedure because attention either lightens up their faces, or banishes them back to their under-world of the Unconscious. It is otherwise with the degenerate and debilitated, who suffer from weakness of will and defective attention. The faint, scarcely recognisable, liminal presentations are perceived at the same time as those that are well lit and centrally focussed. The judgment grows drifting and nebulous like floating fog in the morning wind. Consciousness, aware of the spectrally transparent shapes, seeks in vain to grasp them, and interprets them without confidence, as when one fancies in a cloud resemblances to creatures or things. Whoever has sought on a dark night to discern phenomena on a distant horizon can form an idea of the picture which the world of thought presents to the mind of an asthenic. Lo there! a dark mass! What is it? A tree? A hayrick? A robber? A beast of prey? Ought one to fly? Ought one to attack it? The incapacity to recognise the object, more guessed at than perceived, fills him with uneasiness and anxiety. This is just the condition of the mind of an asthenic in the presence of his liminal presentations. He believes he sees in them a hundred things at once, and he brings all the forms that he seems to discern into connection with the principal presentation which has aroused them. He has, however, a strong feeling that this connection is incomprehensible and inexplicable. He combines presentations into a thought which is in contradiction to all experience, but which he must look upon as equal in validity to all his remaining thoughts and opinions, because it originated in the same way. And even if he wishes to make clear to himself what is really the content of his judgment, and of what particular presentations it is composed, he observes that these presentations are, as a matter of fact, nothing but unrecognisable adumbrations of presentations, to which he vainly seeks to give a name. Now, this state of mind, in which a man is straining to see, thinks he sees, but does not see—in which a man is forced to construct thoughts out of presentations which befool and mock consciousness like will-o’-the-wisps or marsh vapours—in which a man fancies that he perceives inexplicable relations between distinct phenomena and ambiguous formless shadows—this is the condition of mind that is called Mysticism.

From the shadowy thinking of the mystic, springs his washed-out style of expression. Every word, even the most abstract, connotes a concrete presentation or a concept, which, inasmuch as it is formed out of the common attributes of different concrete presentations, betrays its concrete origin. Language has no word for that which one believes he sees as through a mist, without recognisable form. The mystic, however, is conscious of ghostly presentations of this sort without shape or other qualities, and in order to express them he must either use recognised words, to which he gives a meaning wholly different from that which is generally current, or else, feeling the inadequacy of the fund of language created by those of sound mind, he forges for himself special words which, to a stranger, are generally incomprehensible, and the cloudy, chaotic sense of which is intelligible only to himself; or, finally, he embodies the several meanings which he gives to his shapeless representations in as many words, and then succeeds in achieving those bewildering juxtapositions of what is mutually exclusive, those expressions which can in no way be rationally made to harmonize, but which are so typical of the mystic. He speaks, as did the German mystics of the seventeenth and eighteenth centuries, of the ‘cold fire’ of hell, and of the ‘dark light’ of Satan; or, he says, like the degenerate in the twenty-eighth pathological case of Legrain,[79] ‘that God appeared to him in the form of luminous shadows;’ or he remarks, as did another of Legrain’s patients:[80] ‘You have given me an immutable evening’ (soirÉe immutable).[81]

The healthy reader or listener who has confidence in his own judgment, and tests with lucidity and self-dependence, naturally discerns at once that these mystical expressions are senseless, and do but reflect the mystic’s confused manner of thinking. The majority of mankind, however, have neither self-confidence nor the faculty of judging, and cannot throw off the natural inclination to connect some meaning with every word. And since the words of the mystic have no definite meaning in themselves, or in their juxtaposition, a certain meaning is arbitrarily imputed to them, is mysteriously conjured into them. The effect of the mystical method of expression on people who allow themselves to be bewildered is for this reason a very strong one. It gives them food for thought, as they call it; that is to say, it allows them to give way to all kinds of dream-fancies, which is very much easier, and therefore more agreeable, than the toil of reflecting on firmly outlined presentations and thoughts admitting of no evasions and extravagances.[82] It transports their minds to the same condition of mental activity determined by unbridled association of ideas that is peculiar to the mystic; it awakens in them also his ambiguous, unutterable presentations, and makes them divine the strangest and most impossible relations of things to each other. All the weak-headed appear therefore ‘deep’ to the mystic, and this designation has, from the constant use made of it by them, become almost an insult. Only very strong minds are really deep, such as can keep the processes of thought under the discipline of an extraordinarily powerful attention. Such minds are in a position to exploit the association of ideas in the best possible way, to impart the greatest sharpness and clearness to all representations which through them are called into consciousness; to suppress them firmly and rapidly if they are not compatible with the rest; to procure new sense-impressions, if these are necessary in order to make the presentations and judgments predominant at the time in their minds still more vivid and distinct; they gain in this way an incomparably clear picture of the world, and discover true relations among phenomena which, to a weaker attention, must always remain hidden. This true depth of strong select minds is wholly luminous. It scares shadows out of hidden corners, and fills abysses with radiant light. The mystic’s pseudo-depth, on the contrary, is all obscurity. It causes things to appear deep by the same means as darkness, viz., by reason of its rendering their outlines imperceptible. The mystic obliterates the firm outlines of phenomena; he spreads a veil over them, and conceals them in blue vapour. He troubles what is clear, and makes the transparent opaque, as does the cuttle-fish the waters of the ocean. He, therefore, who sees the world through the eyes of a mystic, gazes into a black heaving mass, in which he can always find what he desires, although, and just because, he actually perceives nothing at all. To the weak-headed everything which is clearly, firmly defined, and which, therefore, has strictly but one meaning, is flat. To them everything is profound which has no meaning, and which, therefore, allows them to apply what meaning they please. To them mathematical analysis is flat; theology and metaphysics, deep. The study of Roman law is flat; the dream-book and the prophecies of Nostradamus are deep. The forms assumed by pouring molten lead on New Year’s Eve are the true symbols of their depth.

The content of mystic thought is determined by the individual character and level of culture possessed by each degenerate and hysteric. For we should never forget that the morbidly-affected or exhausted brain is only the soil which receives the seed sown by nurture, education, impressions and experience of life, etc. The seed-grains do not originate in the soil; they only receive in and through it their special irregularities of development, their deformities, and crazy offshoots. The naturalist who loses the faculty of attention becomes the so-called ‘Natural Philosopher,’ or the discoverer of a fourth dimension in space, like the unfortunate ZÖllner. A rough, ignorant person from the low ranks of the people falls into the wildest superstition. The mystic, nurtured in religion and nourished with dogma, refers his shadowy impressions to his beliefs, and interprets them as revelations of the nature of the Trinity, or of the condition of existence before birth or after death. The technologist who has fallen into mysticism worries over impossible inventions, believes himself to be on the track of the solution of the problem of a perpetuum mobile, devises communication between earth and stars, shafts to the glowing core of the earth, and what not. The astronomer becomes an astrologist, the chemist an alchemist and a seeker after the philosopher’s stone; the mathematician labours to square the circle, or to invent a system in which the notion of progress is expressed by a process of integration, the war of 1870 by an equation, and so on.

As was set forth above, the cerebral cortex receives its stimuli, not only from the external nerves, but also from the interior of the organism, from the nerves of separate organs, and the nerve-centres of the spinal cord and the sympathetic system. Every excitement in these centres affects the brain-cells, and arouses in them more or less distinct presentations, which are necessarily related to the activity of the centres from which the stimulus proceeds. A few examples will make this clear, even to the uninitiated. If the organism feels the need of nourishment, and we are hungry, we shall not only be generally conscious of an indeterminate desire for food, but there will also arise in our minds definite representations of dishes, of served repasts, and of all the accessories of eating. If we, from some cause, maybe an affection of the heart or lungs, cannot breathe freely, we have not only a hunger for air, but also accompanying ideas of an uneasy nature, presentiments of unknown dangers, melancholy memories, etc., i.e., representations of circumstances which tend to deprive us of breath or affect us oppressively. During sleep also organic stimuli exert this influence on the cerebral cortex, and to them we owe the so-called somatic dreams (LeibestrÄume), i.e., dream-images about the functioning of any organs which happen not to be in a normal condition.

Now, it is known that certain organic nerve-centres, the sexual centres, namely, in the spinal cord and the medulla oblongata, are frequently malformed, or morbidly irritated among the degenerate. The stimuli proceeding from them therefore awaken, in the brain of patients of this sort, presentations which are more or less remotely connected with the sexual activity. In the consciousness, therefore, of such a subject there always exist, among the other presentations which are aroused by the varying stimuli of the external world, presentations of a sexual character, erotic thoughts being associated with every impression of beings and things. In this way he attains to a state of mind in which he divines mysterious relations among all possible objective phenomena, e.g., a railway-train, the title of his newspaper, a piano on the one hand, and woman on the other; and feels emotions of an erotic nature at sights, words, odours, which would produce no such impression on the mind of a sound person, emotions which he refers to unknown qualities in those sights, words, etc. Hence it comes that in most cases mysticism distinctly takes on a decidedly erotic colouring, and the mystic, if he interprets his inchoate liminal presentations, always tends to ascribe to them an erotic import. The mixture of super-sensuousness and sensuality, of religious and amorous rapture, which characterizes mystic thought, has been noticed even by those observers who do not understand in what way it is brought about.

The mysticism which I have hitherto investigated is the incapacity, due to weakness of will, either innate or acquired, to guide the work of the association of ideas by attention, to draw shadowy liminal representations into the bright focal circle of consciousness, and to suppress presentations which are incompatible with those attended to. There exists, however, another form of mysticism, the cause of which is not defective attention, but an anomaly in the sensitivity of the brain and nervous system. In the healthy organism the afferent nerves convey impressions of the external world in their full freshness to the brain, and the stimulation of the brain-cell is in direct ratio to the intensity of the stimulus conducted to it. Not so is the deportment of a degenerate or exhausted organism. Here the brain may have forfeited its normal irritability; it is blunted, and is only feebly excited by stimuli conveyed to it. Such a brain, as a rule, never succeeds in elaborating sharply-defined impressions. Its thoughts are always shadowy and confounded. There is, however, no occasion for me to depict in detail the characteristics of its mental procedure, for in the higher species of the degenerate a blunted brain is hardly ever met with, and plays no part in art or literature. To the possessor of a sluggishly-reacting brain it hardly ever occurs to compose or paint. He is of account only as forming the creative mystic’s partial and grateful public. Inadequate excitability may moreover be a property of the sensory nerves. This irregularity leads to anomalies in mental life, with which I shall deal exhaustively in the next book. Finally, instead of slow reaction there may exist excessive excitability, and this may be peculiar to the whole nervous system and brain, or only to a portion of the latter. A generally excessive excitability produces those morbidly-sensitive natures in whom the most insignificant phenomena create the most astonishing perceptions; who hear the ‘sobbing of the evening glow,’ shudder at the contact of a flower; distinguish thrilling prophecies and fearful threatenings in the sighing of the wind, etc.[83] Excessive irritability of particular groups of cells of the cerebral cortex gives rise to other phenomena. In the affected part of the brain, stimulated either externally or by adjacent stimuli, in other words, by sense impressions or by association, the disturbance does not in this case proceed in a natural ratio to the strength of the exciting cause, but is stronger and more lasting than is warranted by the stimulus. The aroused group of cells returns to a state of rest either with difficulty or not at all. It attracts large quantities of nutriment for purposes of absorption, withdrawing them from the other parts of the brain. It works like a machine which an unskilful hand has set in motion but cannot stop. If the normal action of the brain-cells may be compared to quiet combustion, the action of a morbidly-irritable group of cells may be said to resemble an explosion, and one, too, which is both violent and persistent. With the stimulus there flames forth in consciousness a presentation, or train of presentations, conceptions and reasonings, which suffuse the mind as with the glare of a conflagration, outshining all other ideas.

The degree of exclusiveness and insistence in the predominance of any presentation is in proportion to the degree of morbid irritability in the particular tract of brain by which it is elaborated. Where the degree is not excessive there arise obsessions which the consciousness recognises as morbid. They do not preclude the coexistence of healthy functioning of the brain, and consciousness acquires the habit of treating these co-existent obsessions as foreign to itself, and of banishing them from its presentations and judgments. In aggravated cases these obsessions grow into fixed ideas. The immoderately excitable portions of the brain work out their ideas with such liveliness that consciousness is filled with them, and can no longer distinguish them from such as are the result of sense-impressions, the nature and strength of which they accurately reflect. Then we reach the stage of hallucinations and delirium. Finally, in the last stage, comes ecstasy, which Ribot calls ‘the acute form of the effort after unity of consciousness.’ In ecstasy the excited part of the brain works with such violence that it suppresses the functioning of all the rest of the brain. The ecstatic subject is completely insensible to external stimuli. There is no perception, no representation, no grouping of presentations into concepts, and of concepts into judgments and reasoning. A single presentation, or group of presentations, fills up consciousness. These presentations are of extreme distinctness and clearness. Consciousness is, as it were, flooded with the blinding light of mid-day. There therefore takes place exactly the reverse of what has been noticed in the case of the ordinary mystic. The ecstatic state is associated with extremely intense emotions, in which the highest bliss is mixed with pain. These emotions accompany every strong and excessive functioning of the nerve-cells, every extraordinary and violent decomposition of nerve-nutriment. The feeling of voluptuousness is an example of the phenomena accompanying extraordinary decompositions in a nerve-cell. In healthy persons the sexual nerve-centres are the only ones which, conformably with their functions, are so differentiated and so adapted that they exercise no uniform or lasting activity, but, for by far the greatest part of the time, are perfectly tranquil, storing up large quantities of nutriment in order, during very short periods, to decompose this suddenly and, as it were, explosively. Every nerve-centre which operates in this way would procure us voluptuous emotion; but precisely among healthy persons there are, except the sexual nerve-centres, none which are compelled to act in this manner, in order to serve the purpose of the organism. Among the degenerate, on the contrary, particular morbidly excited brain-centres operate in this way, and the emotions of delight which accompany their explosive activity are more powerful than sexual feelings, in proportion as the brain-centres are more sensitive than the subordinate and more sluggish spinal centres. One may completely believe the assurances of great ecstatics, such as a St. Theresa, a Mohammed, an Ignatius Loyola, that the bliss accompanying their ecstatic visions is unlike anything earthly, and almost more than a mortal can bear. This latter statement proves that they were conscious of the sharp pain which accompanies nerve-action in overexcited brain-cells, and which, on careful analysis, may be distinguished in every very strong feeling of pleasure. The circumstance that the only normal organic sensation known to us which resembles that of ecstasy is the sexual feeling, explains the fact that ecstatics connect their ecstatic presentations by way of association with the idea of love, and describe the ecstasy itself as a kind of supernatural act of love, as a union of an ineffably high and pure sort with God or the Blessed Virgin. This drawing near to God and the saints is the natural result of a religious training, which begets the habit of looking on everything inexplicable as supernatural, and of bringing it into connection with the doctrines of faith.

We have now seen that mysticism depends upon the incapacity to control the association of ideas by the attention, and that this incapacity results from weakness of will; while ecstasy is a consequence of the morbid irritability of special brain-centres. The incapacity of being attentive occasions, however, besides mysticism, other eccentricities of the intellect, which may here be briefly mentioned. In extreme stages of degeneration, e.g., in idiocy, attention is utterly wanting. No stimulus is able to arouse it, nor is there any external means of making an impression on the brain of the idiot, and awakening his consciousness to definite presentations. In less complete degeneration, i.e., in cases of mental debility, attention may exist, but it is extremely weak and fleeting. Imbeciles (weak minds) present, in graduated intensity, the phenomenon of fugitive thought (Gedankenflucht), i.e., the incapacity to retain, or to unite in a concept or judgment, the representations automatically and reciprocally called into consciousness in conformity with the laws of association, and also that of reverie, which is another form of fugitive thought, but which differs from it in that the particular representations of which it is composed are feebly elaborated, and are therefore shadowy and undefined, sometimes so much so that an imbecile, who in the midst of his reveries is asked of what he is thinking, is not able to state exactly what happens to be present in his consciousness. All observers maintain that the ‘higher degenerate’ is frequently ‘original, brilliant, witty,’ and that whereas he is incapable of activity which demands attention and self-control, he has strong artistic inclinations. All these peculiarities are to be explained by the uncontrolled working of association.

The reader should recall the procedure of that brain which is incapable of attention. A perception arouses a representation which summons into consciousness a thousand other associated representations. The healthy mind suppresses the representations which are contradictory to, or not rationally connected with, the first perception. This the weak-minded cannot do. The mere similarity of sound determines the current of his thought. He hears a word, and feels compelled to repeat it, once or oftener, sometimes to the extent of ‘Echolalia’; or it calls into his consciousness other words similar to it in sound, but not connected with it in meaning,[84] whereupon he thinks and talks in a series of completely disconnected rhymes; or else the words have, besides their similarity of sound, a very remote and weak connection of meaning; this gives rise to punning. Ignorant persons are inclined to call the rhyming and punning of imbeciles witty, not bearing in mind that this way of combining ideas according to the sound of the words frustrates the purposes of the intellect by obscuring the apprehension of the real connections of phenomena. No witticism has ever made easier the discovery of any truth. And whoever has tried to hold a serious conversation with a quibbling person of weak mind will have recognised the impossibility of keeping him in check, of getting from him a logical conclusion, or of making him comprehend a fact or a causal connection. When presentations are connected, not merely according to auditory impressions of simple similarity of sound, but also according to the other laws of association, those juxtapositions of words are effected which the ignorant designate as ‘original modes of expression,’ and which confer upon their originator the reputation of a ‘brilliant’ conversationalist or author. Sollier[85] cites some characteristic examples of the ‘original’ modes of expression of imbeciles. One said to his comrade, ‘You look like a piece of barley-sugar put out to nurse.’ Another expresses the thought that his friend made him laugh so much he could not restrain his saliva, by saying, ‘Tu me fais baver des ronds de chapeaux.’ The junction of words which by their sense have little or no relation to each other is, as a rule, an evidence of imbecility, although it often enough is sensational and mirth-provoking. The cleverness which in Paris is called blague, or boulevard-esprit, the psychologist discerns as imbecility. That this condition goes hand-in-hand with artistic tendencies is easy to understand. All callings which require knowledge of fact, and adaptation to it, presuppose attention. This capacity is wanting in imbeciles; hence they are not fitted for serious professions. Certain artistic occupations, especially those of a subordinate kind, are, on the contrary, quite compatible with uncontrolled association of ideas, reverie, or fugitive thought, because they exact only a very limited adaptation to fact, and therefore have great attractions for persons of weak intellect.

Between the process of thought and movement there exists an exact parallelism explicable by the fact that the elaboration of presentations is nothing else than a modification of the elaboration of the motor impulses. The phenomena of movement make the mechanism of thought more easily apprehensible to the lay mind. The automatic association of muscular contractions corresponds to the association of ideas, their co-ordination to attention. As with defective attention there ensues no intelligent thought, so with faulty co-ordination there can be no appropriate movement. Palsy is equivalent to idiocy, St. Vitus’s dance to obsessions and fixed ideas. The attempts at witticisms of the weak-minded are like beating the air with a sword; the notions and judgments of sound brains are like the careful thrust and parry of skilful fencing. Mysticism finds its reflected image in the aimless and powerless, often hardly discernible, movements of senile and paralytic trembling; and ecstasy is, for a brain-centre, the same state as a prolonged and violent tonic contraction for a muscle or group of muscles.
