455. The phenomena of natural somnambulism occur spontaneously and independently of any known external cause; but, in persons endowed with a special organisation, they may be produced artificially through the action of the mesmeric agent. The only difference between the state designated as mesmeric somnambulism, and natural somnambulism is, that the one is artificially produced, while the other is spontaneous.

Natural somnambulism is a notorious fact, the reality of which few now dispute, notwithstanding the marvellous character of the phenomena it presents. Why, then, should mesmeric somnambulism be regarded as more extraordinary or incredible, simply because it is produced artificially, like so many other things? It has been abused by charlatans, some persons will reply; but that fact only affords an additional reason for not leaving it in their hands. When science shall have taken possession of it, charlatanism will have much less credit with the masses; but, meanwhile, as somnambulism, both natural and artificial, is a fact, and as a fact cannot be argued down, it is making its way, despite the ill-will of its adversaries, and obtaining a footing even in the temple of science, which it is entering by a multitude of side-doors, instead of entering by the principal one. Its right to be there will, ere long, be fully recognised.

For the spiritist, somnambulism is more than a physical phenomenon; it is a light thrown on the subject of psychology; it is a state in which we can study the soul, because in it the soul shows itself, so to say, without covering. Now, one of the phenomena which characterise the soul is clear-seeing independently of the ordinary visual organs. Those who contest this fact do so on the ground that the somnambulist does not see at all times, and at the will of the experimentalist, as with the eyes. Need we be astonished if, the means employed being different, the results are not the same? Is it reasonable to demand identical effects in cases in which the instruments employed are not the same? The soul has its properties just as has the eye; and the former must be judged of by themselves, and not by analogy with the latter.

The cause of the clairvoyance of the mesmeric and of the natural somnambulist is identically the same: it is an attribute of the soul, a faculty inherent in every part of the incorporeal being which is in us, and has no other limits than those assigned to the soul itself. The somnambulist sees wherever his soul can transport itself, at no matter what distance.

In sight at distance, the somnambulist does not see from the point at which his body is, and as though through a telescope. The things he sees are present with him, as though he were at the place where they exist, because his soul is there in reality; and it is for this reason that his body is, as it were, annihilated, and seems to he deprived of sensation, until the moment when the soul comes back and retakes possession of it. This partial separation of the soul and the body is an abnormal state, which may last for a longer or shorter time, but not indefinitely; it is the cause of the fatigue felt by the body after a certain lapse of time, especially when the soul, during that partial separation, busies itself with some active pursuit. The fact that soul-sight or spirit-sight is not circumscribed, and has no definite seat, explains why somnambulists are unable to assign to it any special organ or focus. They see, because they see, without knowing why or how; their sight, as spirit-sight, having no special focus. If they refer their perception to their body, this focus seems to them to be in the organic centres in which the vital activity is greatest, especially in the brain, in the epigastric region, or in whatever organ appears to them to be the point at which the bond between the spirit and the body is most tenacious.

The scope of somnambulistic lucidity is not unlimited. A spirit, even when completely free, only possesses the faculties and the knowledge appertaining to the degree of advancement at which he has arrived, a limitation which becomes still further narrowed when he is united with matter, and thus subjected to its influence. This is the reason why somnambulistic clairvoyance is neither universal nor infallible; and its infallibility is all the less to be counted on when it is turned aside from the aim which has been assigned to it by nature, and made a mere matter of curiosity and experimentation.

In the state of comparative freedom in which the somnambulist finds himself, he enters more easily into communication with other spirits, incarnate or disincarnate; and this communication is established through the contact of the fluids which compose their perispirits, and serve, like the electric wire, for the transmission of thought. The somnambulist, therefore, has no need of articulate speech as a vehicle of thought, which he feels and divines; a mode of perception that renders him eminently accessible to, and impressionable by, the influences of the moral atmosphere in which he finds himself. For the same reason, a numerous concourse of spectators, and especially of those who are attracted by a more or less malevolent curiosity, is essentially unfavourable to the manifestation of his peculiar faculties, which close up, so to say, at the contact of hostile influences, and only unfold freely in intimacy, and under the influence of sympathetic surroundings. The presence of those who are malevolent or antipathetic produces upon him the effect of the contact of the hand upon a sensitive plant.

The somnambulist sees, at the same time, his own spirit and his body; they are, so to say, two beings which represent to him his double existence, spiritual and corporeal, and which, nevertheless, are blended into one by the ties which united them together. The somnambulist does not always comprehend this duality, which often leads him to speak of himself as though he were speaking of another person; in such cases, the corporeal being sometimes speaking to the spiritual being, and the spiritual being sometimes speaking to the corporeal being.

The spirit acquires an increase of knowledge and experience in each of his corporeal

existences. He loses sight of part of these gains during his reincarnation in matter, which is too gross to allow of his remembering them in their entirety; but he remembers them as a spirit. It is thus that some somnambulists give evidence of possessing knowledge beyond their present degree of instruction, and even of their apparent intellectual capacity. The intellectual and scientific inferiority of a somnambulist in his waking state, therefore, proves nothing against his possession of the knowledge he may display in his lucid state. According to the circumstances of the moment and the aim proposed, he may draw this knowledge from the stores of his own experience, from his clairvoyant perception of things actually occurring, or from the counsels which he receives from other spirits; but, in proportion as his own spirit is more or less advanced, he will make his statements more or less correctly.

In the phenomena of somnambulism, whether natural or mesmeric, Providence furnishes us with undeniable proof of the existence and independence of the soul, by causing us to witness the sublime spectacle of its emancipation from the fetters of the body, and thus enabling us to read our future destiny as in an open book. When a somnambulist describes what is taking place at a distance, it is equally evident that he sees what he describes, and that he does not see it with his bodily eyes. He sees himself at that distant point, and he feels himself to be transported thither. Something of himself, therefore, is really present at that distant point; and that something, not being his body, can only be his soul or his spirit.

While man, in search of the causes of his moral being, loses himself in abstract and unintelligible metaphysical subtleties, God places daily before his eyes, and within reach of his hand, the simplest and most certain means for the study of experimental psychology.

Trance is the state in which the soul's independence of the body is made most clearly visible, and, so to say, palpable, to the senses of the observer.

In dreaming and somnambulism, the soul wanders among terrestrial worlds; in trance, it penetrates into a sphere of existence of another order, into that of the etherealised spirits with whom it enters into communication, without, however, being able to overstep certain limits which it could not pass without entirely breaking the links that attach it to the body. Surrounded by novel splendours, enraptured by harmonies unknown to earth, penetrated by bliss that defies description, the soul enjoys a foretaste of celestial beatitude, and may be said to have placed one foot on the threshold of eternity.

In the state of trance, the annihilation of corporeal ties is almost complete. The body no longer possesses anything more than organic life; and we feel that the soul is only held thereto by a single thread, which any further effort on its part would break for ever.

In this state, all earthly thoughts disappear, and give place to the purified perception that is the very essence of our immaterial being. Entirely absorbed in this sublime contemplation, the ecstatic regards the earthly life as being merely a momentary halt upon our eternal way; the successes and misfortunes of this lower world, its gross joys and sorrows, appear to him only as the futile incidents of a journey of which he is delighted to foresee the end.

It is with ecstatics as with somnambulists; their lucidity may be more or less perfect, and their spirit, according as it is more or less elevated, is also more or less apt to apprehend the truth of things. In their abnormal state, there is sometimes more of nervous excitement than of true lucidity; or, to speak more correctly, their nervous excitement impairs their lucidity, and, for this reason, their revelations are often a mixture of truths and errors, of sublime ideas and absurd or even ridiculous fancies. Inferior spirits often take advantage of this nervous excitement (which is always a source of weakness to those who are unable to control it), in order to subjugate the ecstatic; and to this end they assume to his eyes the appearances which confirm him in the ideas and prejudices of his waking state. This subjugation of clairvoyants by the presentation of false appearances is the "rock ahead" of this order of revealment. But all of them are not equally subject to this dangerous misleading; and it is for us to weigh their statements coolly and carefully, and to judge their revelations by the light of science and of reason.

The emancipation of the soul occurs sometimes in the waking state, and gives, to those who are endowed with the faculty designated by the name of second-sight, the power of seeing, hearing, and feeling, beyond the limits of the bodily senses. They perceive things at a distance, at all points to which their soul extends its action; they see them, so to say, athwart their ordinary sight, and as though in a sort of mirage.

At the moment when the phenomenon of second-sight occurs, the physical state of the seer is visibly modified. His glance becomes vague; he looks before him without seeing; his physiognomy reflects an abnormal state of the nervous system. It is evident that his organs of sight have nothing to do with his present perceptions; for his vision continues, even when his eyes are shut.

The faculty of second-sight appears to those who are endowed with it to be as natural as ordinary sight. It seems to them to be an attribute of their being; and they are not aware of its exceptional character. They generally forget this fugitive lucidity, the remembrance of which, becoming more and more vague, disappears at length from their memory like a dream.

The power of second-sight varies from a confused sensation to a clear and distinct perception of things present or distant. In its rudimentary state, it gives to some persons tact, perspicacity, a sort of sureness, in their decisions and actions, that may be styled the rectitude of the moral glance. At a higher degree of development, it awakens presentiments; still further developed, it shows to the seer events that have already happened, or that are about to happen.

Natural and artificial somnambulism, trance, and second-sight are only varieties or modifications of the action of one and the same cause. Like dreams, they are a branch of natural phenomena, and have therefore existed in every age. History shows us that they have been known, and even abused, from the remotest antiquity; and they furnish the explanation of innumerable facts which superstitious prejudices have led men to regard as supernatural.
