WHAT PSYCHICAL RESEARCH HAS ACCOMPLISHED.
"The great field for new discoveries," said a scientific friend to me the other day, "is always the unclassified residuum." Round about the accredited and orderly facts of every science there ever floats a sort of dust-cloud of exceptional observations, of occurrences minute and irregular and seldom met with, which it always proves more easy to ignore than to attend to. The ideal of every science is that of a closed and completed system of truth. The charm of most sciences to their more passive disciples consists in their appearing, in fact, to wear just this ideal form. Each one of our various _ologies_ seems to offer a definite head of classification for every possible phenomenon of the sort which it professes to cover; and so far from free is most men's fancy, that, when a consistent and organized scheme of this sort has once been comprehended and assimilated, a different scheme is unimaginable. No alternative, whether to whole or parts, can any longer be conceived as possible. Phenomena unclassifiable within the system are therefore paradoxical absurdities, and must be held untrue. When, moreover, as so often happens, the reports of them are vague and indirect; when they come as mere marvels and oddities rather than as things of serious moment,--one neglects or denies them with the best of scientific consciences. Only the born geniuses let themselves be worried and fascinated by these outstanding exceptions, and get no peace till they are brought within the fold. Your Galileos, Galvanis, Fresnels, Purkinjes, and Darwins are always getting confounded and troubled by insignificant things. Any one will renovate his science who will steadily look after the irregular phenomena. And when the science is renewed, its new formulas often have more of the voice of the exceptions in them than of what were supposed to be the rules.
No part of the unclassified residuum has usually been treated with a more contemptuous scientific disregard than the mass of phenomena generally called _mystical_. Physiology will have nothing to do with them. Orthodox psychology turns its back upon them. Medicine sweeps them out; or, at most, when in an anecdotal vein, records a few of them as 'effects of the imagination,'--a phrase of mere dismissal, whose meaning, in this connection, it is impossible to make precise. All the while, however, the phenomena are there, lying broadcast over the surface of history. No matter where you open its pages, you find things recorded under the name of divinations, inspirations, demoniacal possessions, apparitions, trances, ecstasies, miraculous healings and productions of disease, and occult powers possessed by peculiar individuals over persons and things in their neighborhood. We suppose that 'mediumship' originated in Rochester, N. Y., and animal magnetism with Mesmer; but once look behind the pages of official history, in personal memoirs, legal documents, and popular narratives and books of anecdote, and you will find that there never was a time when these things were not reported just as abundantly as now. We college-bred gentry, who follow the stream of cosmopolitan culture exclusively, not infrequently stumble upon some old-established journal, or some voluminous native author, whose names are never heard of in _our_ circle, but who number their readers by the quarter-million. It always gives us a little shock to find this mass of human beings not only living and ignoring us and all our gods, but actually reading and writing and cogitating without ever a thought of our canons and authorities. Well, a public no less large keeps and transmits from generation to generation the traditions and practices of the occult; but academic science cares as little for its beliefs and opinions as you, gentle reader, care for those of the readers of the Waverley and the Fireside Companion. To no one type of mind is it given to discern the totality of truth. Something escapes the best of us,--not accidentally, but systematically, and because we have a twist. The scientific-academic mind and the feminine-mystical mind shy from each other's facts, just as they fly from each other's temper and spirit. Facts are there only for those who have a mental affinity with them. When once they are indisputably ascertained and admitted, the academic and critical minds are by far the best fitted ones to interpret and discuss them,--for surely to pass from mystical to scientific speculations is like passing from lunacy to sanity; but on the other hand if there is anything which human history demonstrates, it is the extreme slowness with which the ordinary academic and critical mind acknowledges facts to exist which present themselves as wild facts, with no stall or pigeon-hole, or as facts which threaten to break up the accepted system. In psychology, physiology, and medicine, wherever a debate between the mystics and the scientifics has been once for all decided, it is the mystics who have usually proved to be right about the _facts_, while the scientifics had the better of it in respect to the theories. The most recent and flagrant example of this is 'animal magnetism,' whose facts were stoutly dismissed as a pack of lies by academic medical science the world over, until the non-mystical theory of 'hypnotic suggestion' was found for them,--when they were admitted to be so excessively and dangerously common that special penal laws, forsooth, must be passed to keep all persons unequipped with medical diplomas from taking part in their production. Just so stigmatizations, invulnerabilities, instantaneous cures, inspired discourses, and demoniacal possessions, the records of which were shelved in our libraries but yesterday in the alcove headed 'superstitions,' now, under the brand-new title of 'cases of hystero-epilepsy,' are republished, reobserved, and reported with an even too credulous avidity.
Repugnant as the mystical style of philosophizing maybe (especially when self-complacent), there is no sort of doubt that it goes with a gift for meeting with certain kinds of phenomenal experience. The writer of these pages has been forced in the past few years to this admission; and he now believes that he who will pay attention to facts of the sort dear to mystics, while reflecting upon them in academic-scientific ways, will be in the best possible position to help philosophy. It is a circumstance of good augury that certain scientifically trained minds in all countries seem drifting to the same conclusion. The Society for Psychical Research has been one means of bringing science and the occult together in England and America; and believing that this Society fulfils a function which, though limited, is destined to be not unimportant in the organization of human knowledge, I am glad to give a brief account of it to the uninstructed reader.
According to the newspaper and drawing-room myth, soft-headedness and idiotic credulity are the bond of sympathy in this Society, and general wonder-sickness its dynamic principle. A glance at the membership fails, however, to corroborate this view. The president is Prof. Henry Sidgwick, known by his other deeds as the most incorrigibly and exasperatingly critical and sceptical mind in England. The hard-headed Arthur Balfour is one vice-president, and the hard-headed Prof. J. P. Langley, secretary of the Smithsonian Institution, is another. Such men as Professor Lodge, the eminent English physicist, and Professor Richet, the eminent French physiologist, are among the most active contributors to the Society's Proceedings; and through the catalogue of membership are sprinkled names honored throughout the world for their scientific capacity. In fact, were I asked to point to a scientific journal where hard-headedness and never-sleeping suspicion of sources of error might be seen in their full bloom, I think I should have to fall back on the Proceedings of the Society for Psychical Research. The common run of papers, say on physiological subjects, which one finds in other professional organs, are apt to show a far lower level of critical consciousness. Indeed, the rigorous canons of evidence applied a few years ago to testimony in the case of certain 'mediums' led to the secession from the Society of a number of spiritualists. Messrs. Stainton Moses and A. R. Wallace, among others, thought that no experiences based on mere eyesight could ever have a chance to be admitted as true, if such an impossibly exacting standard of proof were insisted on in every case.
The S. P. R., as I shall call it for convenience, was founded in 1882 by a number of gentlemen, foremost among whom seem to have been Professors Sidgwick, W. F. Barrett, and Balfour Stewart, and Messrs. R. H. Hutton, Hensleigh Wedgwood, Edmund Gurney, and F. W. H. Myers. Their purpose was twofold,--first, to carry on systematic experimentation with hypnotic subjects, mediums, clairvoyants, and others; and, secondly, to collect evidence concerning apparitions, haunted houses, and similar phenomena which are incidentally reported, but which, from their fugitive character, admit of no deliberate control. Professor Sidgwick, in his introductory address, insisted that the divided state of public opinion on all these matters was a scandal to science,--absolute disdain on _a priori_ grounds characterizing what may be called professional opinion, while indiscriminate credulity was too often found among those who pretended to have a first-hand acquaintance with the facts.
As a sort of weather bureau for accumulating reports of such meteoric phenomena as apparitions, the S. P. R. has done an immense amount of work. As an experimenting body, it cannot be said to have completely fulfilled the hopes of its founders. The reasons for this lie in two circumstances: first, the clairvoyant and other subjects who will allow themselves to be experimented upon are few and far between; and, secondly, work with them takes an immense amount of time, and has had to be carried on at odd intervals by members engaged in other pursuits. The Society has not yet been rich enough to control the undivided services of skilled experimenters in this difficult field. The loss of the lamented Edmund Gurney, who more than any one else had leisure to devote, has been so far irreparable. But were there no experimental work at all, and were the S. P. R. nothing but a weather-bureau for catching sporadic apparitions, etc., in their freshness, I am disposed to think its function indispensable in the scientific organism. If any one of my readers, spurred by the thought that so much smoke must needs betoken fire, has ever looked into the existing literature of the supernatural for proof, he will know what I mean. This literature is enormous, but it is practically worthless for evidential purposes. Facts enough are cited, indeed; but the records of them are so fallible and imperfect that at most they lead to the opinion that it may be well to keep a window open upon that quarter in one's mind.
In the S. P. R.'s Proceedings, on the contrary, a different law prevails. Quality, and not mere quantity, is what has been mainly kept in mind. The witnesses, where possible, have in every reported case been cross-examined personally, the collateral facts have been looked up, and the story appears with its precise coefficient of evidential worth stamped on it, so that all may know just what its weight as proof may be. Outside of these Proceedings, I know of no systematic attempt to _weigh_ the evidence for the supernatural. This makes the value of the volumes already published unique; and I firmly believe that as the years go on and the ground covered grows still wider, the Proceedings will more and more tend to supersede all other sources of information concerning phenomena traditionally deemed occult. Collections of this sort are usually best appreciated by the rising generation. The young anthropologists and psychologists who will soon have full occupancy of the stage will feel how great a scientific scandal it has been to leave a great mass of human experience to take its chances between vague tradition and credulity on the one hand and dogmatic denial at long range on the other, with no body of persons extant who are willing and competent to study the matter with both patience and rigor. If the Society lives long enough for the public to become familiar with its presence, so that any apparition, or house or person infested with unaccountable noises or disturbances of material objects, will as a matter of course be reported to its officers, we shall doubtless end by having a mass of facts concrete enough to theorize upon. Its sustainers, therefore, should accustom themselves to the idea that its first duty is simply to exist from year to year and perform this recording function well, though no conclusive results of any sort emerge at first. All our learned societies have begun in some such modest way.
But one cannot by mere outward organization make much progress in matters scientific. Societies can back men of genius, but can never take their place. The contrast between the parent Society and the American Branch illustrates this. In England, a little group of men with enthusiasm and genius for the work supplied the nucleus; in this country, Mr. Hodgson had to be imported from Europe before any tangible progress was made. What perhaps more than anything else has held the Society together in England is Professor Sidgwick's extraordinary gift of inspiring confidence in diverse sorts of people. Such tenacity of interest in the result and such absolute impartiality in discussing the evidence are not once in a century found in an individual. His obstinate belief that there is something yet to be brought to light communicates patience to the discouraged; his constitutional inability to draw any precipitate conclusion reassures those who are afraid of being dupes. Mrs. Sidgwick--a sister, by the way, of the great Arthur Balfour--is a worthy ally of her husband in this matter, showing a similarly rare power of holding her judgment in suspense, and a keenness of observation and capacity for experimenting with human subjects which are rare in either sex.
The _worker_ of the Society, as originally constituted, was Edmund Gurney. Gurney was a man of the rarest sympathies and gifts. Although, like Carlyle, he used to groan under the burden of his labors, he yet exhibited a colossal power of dispatching business and getting through drudgery of the most repulsive kind. His two thick volumes on 'Phantasms of the Living,' collected and published in three years, are a proof of this. Besides this, he had exquisite artistic instincts, and his massive volume on 'The Power of Sound' was, when it appeared, the most important work on aesthetics in the English language. He had also the tenderest heart and a mind of rare metaphysical power, as his volumes of essays, 'Tertium Quid,' will prove to any reader. Mr. Frederic Myers, already well known as one of the most brilliant of English essayists, is the _ingenium praefervidum_ of the S. P. R. Of the value of Mr. Myers's theoretic writings I will say a word later. Dr. Hodgson, the American secretary, is distinguished by a balance of mind almost as rare in its way as Sidgwick's. He is persuaded of the reality of many of the phenomena called spiritualistic, but he also has uncommon keenness in detecting error; and it is impossible to say in advance whether it will give him more satisfaction to confirm or to smash a given case offered to his examination.
It is the opinion of all who took part in these latter experiments that sources of conscious and unconscious deception were sufficiently excluded, and that the large percentage of correct reproductions by the subjects of words, diagrams, and sensations occupying other persons' consciousness were entirely inexplicable as results of chance. The witnesses of these performances were in fact all so satisfied of the genuineness of the phenomena, that 'telepathy' has figured freely in the papers of the Proceedings and in Gurney's book on Phantasms as a _vera causa_ on which additional hypotheses might be built. No mere reader can be blamed, however, if he demand, for so revolutionary a belief, a more overwhelming bulk of testimony than has yet been supplied. Any day, of course, may bring in fresh experiments in successful picture-guessing. But meanwhile, and lacking that, we can only point out that the present data are strengthened in the flank, so to speak, by all observations that tend to corroborate the possibility of other kindred phenomena, such as telepathic impression, clairvoyance, or what is called 'test-mediumship.' The wider genus will naturally cover the narrower species with its credit.
Gurney's papers on hypnotism must be mentioned next. Some of them are less concerned with establishing new facts than with analyzing old ones. But omitting these, we find that in the line of pure observation Gurney claims to have ascertained in more than one subject the following phenomenon: The subject's hands are thrust through a blanket, which screens the operator from his eyes, and his mind is absorbed in conversation with a third person. The operator meanwhile points with his finger to one of the fingers of the subject, which finger alone responds to this silent selection by becoming stiff or anaesthetic, as the case may be. The interpretation is difficult, but the phenomenon, which I have myself witnessed, seems authentic.
Another observation made by Gurney seems to prove the possibility of the subject's mind being directly influenced by the operator's. The hypnotized subject responds, or fails to respond, to questions asked by a third party according to the operator's silent permission or refusal. Of course, in these experiments all obvious sources of deception were excluded. But Gurney's most important contribution to our knowledge of hypnotism was his series of experiments on the automatic writing of subjects who had received post-hypnotic suggestions. For example, a subject during trance is told that he will poke the fire in six minutes after waking. On being waked he has no memory of the order, but while he is engaged in conversation his hand is placed on a _planchette_, which immediately writes the sentence, "P., you will poke the fire in six minutes." Experiments like this, which were repeated in great variety, seem to prove that below the upper consciousness the hypnotic consciousness persists, engrossed with the suggestion and able to express itself through the involuntarily moving hand.
Gurney shares, therefore, with Janet and Binet, the credit of demonstrating the simultaneous existence of two different strata of consciousness, ignorant of each other, in the same person. The 'extra-consciousness,' as one may call it, can be kept on tap, as it were, by the method of automatic writing. This discovery marks a new era in experimental psychology, and it is impossible to overrate its importance. But Gurney's greatest piece of work is his laborious 'Phantasms of the Living.' As an example of the drudgery stowed away in the volumes, it may suffice to say that in looking up the proofs for the alleged physical phenomena of witchcraft, Gurney reports a careful search through two hundred and sixty books on the subject, with the result of finding no first-hand evidence recorded in the trials except the confessions of the victims themselves; and these, of course, are presumptively due to either torture or hallucination. This statement, made in an unobtrusive note, is only one instance of the care displayed throughout the volumes. In the course of these, Gurney discusses about seven hundred cases of apparitions which he collected. A large number of these were 'veridical,' in the sense of coinciding with some calamity happening to the person who appeared. Gurney's explanation is that the mind of the person undergoing the calamity was at that moment able to impress the mind of the percipient with an hallucination.
Apparitions, on this 'telepathic' theory, may be called 'objective' facts, although they are not 'material' facts. In order to test the likelihood of such veridical hallucinations being due to mere chance, Gurney instituted the 'census of hallucinations,' which has been continued with the result of obtaining answers from over twenty-five thousand persons, asked at random in different countries whether, when in good health and awake, they had ever heard a voice, seen a form, or felt a touch which no material presence could account for. The result seems to be, roughly speaking, that in England about one adult in ten has had such an experience at least once in his life, and that of the experiences themselves a large number coincide with some distant event. The question is, Is the frequency of these latter cases too great to be deemed fortuitous, and must we suppose an occult connection between the two events? Mr. and Mrs. Sidgwick have worked out this problem on the basis of the English returns, seventeen thousand in number, with a care and thoroughness that leave nothing to be desired. Their conclusion is that the cases where the apparition of a person is seen on the day of his death are four hundred and forty times too numerous to be ascribed to chance. The reasoning employed to calculate this number is simple enough. If there be only a fortuitous connection between the death of an individual and the occurrence of his apparition to some one at a distance, the death is no more likely to fall on the same day as the apparition than it is to occur on the same day with any other event in nature. But the chance-probability that any individual's death will fall on any given day marked in advance by some other event is just equal to the chance-probability that the individual will die at all on any specified day; and the national death-rate gives that probability as one in nineteen thousand. If, then, when the death of a person coincides with an apparition of the same person, the coincidence be merely fortuitous, it ought not to occur oftener than once in nineteen thousand cases. As a matter of fact, however, it does occur (according to the census) once in forty-three cases, a number (as aforesaid) four hundred and forty times too great. The American census, of some seven thousand answers, gives a remarkably similar result. Against this conclusion the only rational answer that I can see is that the data are still too few; that the net was not cast wide enough; and that we need, to get fair averages, far more than twenty-four thousand answers to the census question. This may, of course, be true, though it seems exceedingly unlikely; and in our own twenty-four thousand answers veridical cases may possibly have heaped themselves unduly.
The next topic worth mentioning in the Proceedings is the discussion of the physical phenomena of mediumship (slate-writing, furniture-moving, and so forth) by Mrs. Sidgwick, Mr. Hodgson, and 'Mr. Davey.' This, so far as it goes, is destructive of the claims of all the mediums examined. 'Mr. Davey' himself produced fraudulent slate-writing of the highest order, while Mr. Hodgson, a 'sitter' in his confidence, reviewed the written reports of the series of his other sitters,--all of them intelligent persons,--and showed that in every case they failed to see the essential features of what was done before their eyes. This Davey-Hodgson contribution is probably the most damaging document concerning eye-witnesses' evidence that has ever been produced. Another substantial bit of work based on personal observation is Mr. Hodgson's report on Madame Blavatsky's claims to physical mediumship. This is adverse to the lady's pretensions; and although some of Madame Blavatsky's friends make light of it, it is a stroke from which her reputation will not recover.
Physical mediumship in all its phases has fared hard in the Proceedings. The latest case reported on is that of the famous Eusapia Paladino, who being detected in fraud at Cambridge, after a brilliant career of success on the continent, has, according to the draconian rules of method which govern the Society, been ruled out from a further hearing. The case of Stainton Moses, on the other hand, concerning which Mr. Myers has brought out a mass of unpublished testimony, seems to escape from the universal condemnation, and appears to force upon us what Mr. Andrew Lang calls the choice between a moral and a physical miracle.
In the case of Mrs. Piper, not a physical but a trance medium, we seem to have no choice offered at all. Mr. Hodgson and others have made prolonged study of this lady's trances, and are all convinced that super-normal powers of cognition are displayed therein. These are _prima facie_ due to 'spirit-control.' But the conditions are so complex that a dogmatic decision either for or against the spirit-hypothesis must as yet be postponed.
One of the most important experimental contributions to the Proceedings is the article of Miss X. on 'Crystal Vision.' Many persons who look fixedly into a crystal or other vaguely luminous surface fall into a kind of daze, and see visions. Miss X. has this susceptibility in a remarkable degree, and is, moreover, an unusually intelligent critic. She reports many visions which can only be described as apparently clairvoyant, and others which beautifully fill a vacant niche incur knowledge of subconscious mental operations. For example, looking into the crystal before breakfast one morning she reads in printed characters of the death of a lady of her acquaintance, the date and other circumstances all duly appearing in type. Startled by this, she looks at the 'Times' of the previous day for verification, and there among the deaths are the identical words which she has seen. On the same page of the Times are other items which she remembers reading the day before; and the only explanation seems to be that her eyes then inattentively observed, so to speak, the death-item, which forthwith fell into a special corner of her memory, and came out as a visual hallucination when the peculiar modification of consciousness induced by the crystal-gazing set in.
Passing from papers based on observation to papers based on narrative, we have a number of ghost stories, etc., sifted by Mrs. Sidgwick and discussed by Messrs. Myers and Podmore. They form the best ghost literature I know of from the point of view of emotional interest. As to the conclusions drawn, Mrs. Sidgwick is rigorously non-committal, while Mr. Myers and Mr. Podmore show themselves respectively hospitable and inhospitable to the notion that such stories have a basis of objectivity dependent on the continued existence of the dead.
I must close my gossip about the Proceedings by naming what, after all, seems to me the most important part of its contents. This is the long series of articles by Mr. Myers on what he now calls the 'subliminal self,' or what one might designate as ultra-marginal consciousness. The result of Myers's learned and ingenious studies in hypnotism, hallucinations, automatic writing, mediumship, and the whole series of allied phenomena is a conviction which he expresses in the following terms:--
"Each of us is in reality an abiding psychical entity far more extensive than he knows,--an individuality which can never express itself completely through any corporeal manifestation. The self manifests itself through the organism; but there is always some part of the self unmanifested, and always, as it seems, some power of organic expression in abeyance or reserve."
The ordinary consciousness Mr. Myers likens to the visible part of the solar spectrum; the total consciousness is like that spectrum prolonged by the inclusion of the ultra-red and ultra-violet rays. In the psychic spectrum the 'ultra' parts may embrace a far wider range, both of physiological and of psychical activity, than is open to our ordinary consciousness and memory. At the lower end we have the _physiological_ extension, mind-cures, 'stigmatization' of ecstatics, etc.; in the upper, the hyper-normal cognitions of the medium-trance. Whatever the judgment of the future may be on Mr. Myers's speculations, the credit will always remain to them of being the first attempt in any language to consider the phenomena of hallucination, hypnotism, automatism, double personality, and mediumship as connected parts of one whole subject. All constructions in this field must be provisional, and it is as something provisional that Mr. Myers offers us his formulations. But, thanks to him, we begin to see for the first time what a vast interlocked and graded system these phenomena, from the rudest motor-automatisms to the most startling sensory-apparition, form. Quite apart from Mr. Myers's conclusions, his methodical treatment of them by classes and series is the first great step toward overcoming the distaste of orthodox science to look at them at all.
One's reaction on hearsay testimony is always determined by one's own experience. Most men who have once convinced themselves, by what seems to them a careful examination, that any one species of the supernatural exists, begin to relax their vigilance as to evidence, and throw the doors of their minds more or less wide open to the supernatural along its whole extent. To a mind that has thus made its _salto mortale_, the minute work over insignificant cases and quiddling discussion of 'evidential values,' of which the Society's reports are full, seems insufferably tedious. And it is so; few species of literature are more truly dull than reports of phantasms. Taken simply by themselves, as separate facts to stare at, they appear so devoid of meaning and sweep, that, even were they certainly true, one would be tempted to leave them out of one's universe for being so idiotic. Every other sort of fact has some context and continuity with the rest of nature. These alone are contextless and discontinuous.
Hence I think that the sort of loathing--no milder word will do--which the very words 'psychical research' and 'psychical researcher' awaken in so many honest scientific breasts is not only natural, but in a sense praiseworthy. A man who is unable himself to conceive of any _orbit_ for these mental meteors can only suppose that Messrs. Gurney, Myers, & Co.'s mood in dealing with them must be that of silly marvelling at so many detached prodigies. And such prodigies! So science simply falls back on her general _non-possumus_; and most of the would-be critics of the Proceedings have been contented to oppose to the phenomena recorded the simple presumption that in some way or other the reports _must_ be fallacious,--for so far as the order of nature has been subjected to really scientific scrutiny, it always has been proved to run the other way. But the oftener one is forced to reject an alleged sort of fact by the use of this mere presumption, the weaker does the presumption itself get to be; and one might in course of time use up one's presumptive privileges in this way, even though one started (as our anti-telepathists do) with as good a case as the great induction of psychology that all our knowledge comes by the use of our eyes and ears and other senses. And we must remember also that this undermining of the strength of a presumption by reiterated report of facts to the contrary does not logically require that the facts in question should all be well proved. A lot of rumors in the air against a business man's credit, though they might all be vague, and no one of them amount to proof that he is unsound, would certainly weaken the _presumption_ of his soundness. And all the more would they have this effect if they formed what Gurney called a fagot and not a chain,--that is, if they were independent of one another, and came from different quarters. Now, the evidence for telepathy, weak and strong, taken just as it comes, forms a fagot and not a chain. No one item cites the content of another item as part of its own proof. But taken together the items have a certain general consistency; there is a method in their madness, so to speak. So each of them adds presumptive value to the lot; and cumulatively, as no candid mind can fail to see, they subtract presumptive force from the orthodox belief that there can be nothing in any one's intellect that has not come in through ordinary experiences of sense.
But it is a miserable thing for a question of truth to be confined to mere presumption and counter-presumption, with no decisive thunderbolt of fact to clear the baffling darkness. And, sooth to say, in talking so much of the merely presumption-weakening value of our records, I have myself been wilfully taking the point of view of the so-called 'rigorously scientific' disbeliever, and making an _ad hominem_ plea. My own point of view is different. For me the thunderbolt _has_ fallen, and the orthodox belief has not merely had its presumption weakened, but the truth itself of the belief is decisively overthrown. If I may employ the language of the professional logic-shop, a universal proposition can be made untrue by a particular instance. If you wish to upset the law that all crows are black, you must not seek to show that no crows are; it is enough if you prove one single crow to be white. My own white crow is Mrs. Piper. In the trances of this medium, I cannot resist the conviction that knowledge appears which she has never gained by the ordinary waking use of her eyes and ears and wits. What the source of this knowledge may be I know not, and have not the glimmer of an explanatory suggestion to make; but from admitting the fact of such knowledge I can see no escape. So when I turn to the rest of the evidence, ghosts and all, I cannot carry with me the irreversibly negative bias of the 'rigorously scientific' mind, with its presumption as to what the true order of nature ought to be. I feel as if, though the evidence be flimsy in spots, it may nevertheless collectively carry heavy weight. The rigorously scientific mind may, in truth, easily overshoot the mark. Science means, first of all, a certain dispassionate method. To suppose that it means a certain set of results that one should pin one's faith upon and hug forever is sadly to mistake its genius, and degrades the scientific body to the status of a sect.
We all, scientists and non-scientists, live on some inclined plane of credulity. The plane tips one way in one man, another way in another; and may he whose plane tips in no way be the first to cast a stone! As a matter of fact, the trances I speak of have broken down for my own mind the limits of the admitted order of nature. Science, so far as science denies such exceptional occurrences, lies prostrate in the dust for me; and the most urgent intellectual need which I feel at present is that science be built up again in a form in which such things may have a positive place. Science, like life, feeds on its own decay. New facts burst old rules; then newly divined conceptions bind old and new together into a reconciling law.
And here is the real instructiveness of Messrs. Myers and Gurney's work. They are trying with the utmost conscientiousness to find a reconciling conception which shall subject the old laws of nature to the smallest possible strain. Mr. Myers uses that method of gradual approach which has performed such wonders in Darwin's hands. When Darwin met a fact which seemed a poser to his theory, his regular custom, as I have heard an able colleague say, was to fill in all round it with smaller facts, as a wagoner might heap dirt round a big rock in the road, and thus get his team over without upsetting. So Mr. Myers, starting from the most ordinary facts of inattentive consciousness, follows this clue through a long series which terminates in ghosts, and seeks to show that these are but extreme manifestations of a common truth,--the truth that the invisible segments of our minds are susceptible, under rarely realized conditions, of acting and being acted upon by the invisible segments of other conscious lives. This may not be ultimately true (for the theosophists, with their astral bodies and the like, may, for aught I now know, prove to be on the correcter trail), but no one can deny that it is in good scientific form,--for science always takes a known kind of phenomenon, and tries to extend its range.
I have myself, as American agent for the census, collected hundreds of cases of hallucination in healthy persons. The result is to make me feel that we all have potentially a 'subliminal' self, which may make at any time irruption into our ordinary lives. At its lowest, it is only the depository of our forgotten memories; at its highest, we do not know what it is at all. Take, for instance, a series of cases. During sleep, many persons have something in them which measures the flight of time better than the waking self does. It wakes them at a preappointed hour; it acquaints them with the moment when they first awake. It may produce an hallucination,--as in a lady who informs me that at the instant of waking she has a vision of her watch-face with the hands pointing (as she has often verified) to the exact time. It may be the feeling that some physiological period has elapsed; but, whatever it is, it is subconscious.
A subconscious something may also preserve experiences to which we do not openly attend. A lady taking her lunch in town finds herself without her purse. Instantly a sense comes over her of rising from the breakfast-table and hearing her purse drop upon the floor. On reaching home she finds nothing under the table, but summons the servant to say where she has put the purse. The servant produces it, saying; "How did you know where it was? You rose and left the room as if you did n't know you 'd dropped it." The same subconscious something may recollect what we have forgotten. A lady accustomed to taking salicylate of soda for muscular rheumatism wakes one early winter morning with an aching neck. In the twilight she takes what she supposes to be her customary powder from a drawer, dissolves it in a glass of water, and is about to drink it down, when she feels a sharp slap on her shoulder and hears a voice in her ear saying, "Taste it!" On examination, she finds she has got a morphine powder by mistake. The natural interpretation is that a sleeping memory of the morphine powders awoke in this quasi-explosive way. A like explanation offers itself as most plausible for the following case: A lady, with little time to catch the train, and the expressman about to call, is excitedly looking for the lost key of a packed trunk. Hurrying upstairs with a bunch of keys, proved useless, in her hand, she hears an 'objective' voice distinctly say, "Try the key of the cake-box." Being tried, it fits. This also may well have been the effect of forgotten experience.
Now, the effect is doubtless due to the same hallucinatory mechanism; but the source is less easily assigned as we ascend the scale of cases. A lady, for instance, goes after breakfast to see about one of her servants who has become ill over night. She is startled at distinctly reading over the bedroom door in gilt letters the word 'small-pox.' The doctor is sent for, and ere long pronounces small-pox to be the disease, although the lady says, "The thought of the girl's having small-pox never entered my mind till I saw the apparent inscription." Then come other cases of warning; for example, that of a youth sitting in a wagon under a shed, who suddenly hears his dead mother's voice say, "Stephen, get away from here quick!" and jumps out just in time to see the shed-roof fall.
After this come the experiences of persons appearing to distant friends at or near the hour of death. Then, too, we have the trance-visions and utterances, which may appear astonishingly profuse and continuous, and maintain a fairly high intellectual level. For all these higher phenomena, it seems to me that while the proximate mechanism is that of 'hallucination,' it is straining an hypothesis unduly to name any ordinary subconscious mental operation--such as expectation, recollection, or inference from inattentive perception--as the ultimate cause that starts it up. It is far better tactics, if you wish to get rid of mystery, to brand the narratives themselves as unworthy of trust. The trustworthiness of most of them is to my own mind far from proved. And yet in the light of the medium-trance, which is proved, it seems as if they might well all be members of a natural kind of fact of which we do not yet know the full extent.
Thousands of sensitive organizations in the United States to-day live as steadily in the light of these experiences, and are as indifferent to modern science, as if they lived in Bohemia in the twelfth century. They are indifferent to science, because science is so callously indifferent to their experiences. Although in its essence science only stands for a method and for no fixed belief, yet as habitually taken, both by its votaries and outsiders, it is identified with a certain fixed belief,--the belief that the hidden order of nature is mechanical exclusively, and that non-mechanical categories are irrational ways of conceiving and explaining even such things as human life. Now, this mechanical rationalism, as one may call it, makes, if it becomes one's only way of thinking, a violent breach with the ways of thinking that have played the greatest part in human history. Religious thinking, ethical thinking, poetical thinking, teleological, emotional, sentimental thinking, what one might call the personal view of life to distinguish it from the impersonal and mechanical, and the romantic view of life to distinguish it from the rationalistic view, have been, and even still are, outside of well-drilled scientific circles, the dominant forms of thought. But for mechanical rationalism, personality is an insubstantial illusion. The chronic belief of mankind, that events may happen for the sake of their personal significance, is an abomination; and the notions of our grandfathers about oracles and omens, divinations and apparitions, miraculous changes of heart and wonders worked by inspired persons, answers to prayer and providential leadings, are a fabric absolutely baseless, a mass of sheer _un_truth.
Now, of course, we must all admit that the excesses to which the romantic and personal view of nature may lead, if wholly unchecked by impersonal rationalism, are direful. Central African Mumbo-jumboism is one of unchecked romanticism's fruits. One ought accordingly to sympathize with that abhorrence of romanticism as a sufficient world-theory; one ought to understand that lively intolerance of the least grain of romanticism in the views of life of other people, which are such characteristic marks of those who follow the scientific professions to-day. Our debt to science is literally boundless, and our gratitude for what is positive in her teachings must be correspondingly immense. But the S. P. R.'s Proceedings have, it seems to me, conclusively proved one thing to the candid reader; and that is that the verdict of pure insanity, of gratuitous preference for error, of superstition without an excuse, which the scientists of our day are led by their intellectual training to pronounce upon the entire thought of the past, is a most shallow verdict. The personal and romantic view of life has other roots besides wanton exuberance of imagination and perversity of heart. It is perennially fed by _facts of experience_, whatever the ulterior interpretation of those facts may prove to be; and at no time in human history would it have been less easy than now--at most times it would have been much more easy--for advocates with a little industry to collect in its favor an array of contemporary documents as good as those which our publications present. These documents all relate to real experiences of persons. These experiences have three characters in common: They are capricious, discontinuous, and not easily controlled; they require peculiar persons for their production; their significance seems to be wholly for personal life. Those who preferentially attend to them, and still more those who are individually subject to them, not only easily may find, but are logically bound to find, in them valid arguments for their romantic and personal conception of the world's course. Through my slight participation in the investigations of the S. P. R. I have become acquainted with numbers of persons of this sort, for whom the very word 'science' has become a name of reproach, for reasons that I now both understand and respect. It is the intolerance of science for such phenomena as we are studying, her peremptory denial either of their existence or of their significance (except as proofs of man's absolute innate folly), that has set science so apart from the common sympathies of the race. I confess that it is on this, its humanizing mission, that the Society's best claim to the gratitude of our generation seems to me to depend. It has restored continuity to history. It has shown some reasonable basis for the most superstitious aberrations of the foretime. It has bridged the chasm, healed the hideous rift that science, taken in a certain narrow way, has shot into the human world.
I will even go one step farther. When from our present advanced standpoint we look back upon the past stages of human thought, whether it be scientific thought or theological thought, we are amazed that a universe which appears to us of so vast and mysterious a complication should ever have seemed to any one so little and plain a thing. Whether it be Descartes's world or Newton's, whether it be that of the materialists of the last century or that of the Bridgewater treatises of our own, it always looks the same to us,--incredibly perspectiveless and short. Even Lyell's, Faraday's, Mill's, and Darwin's consciousness of their respective subjects are already beginning to put on an infantile and innocent look. Is it then likely that the science of our own day will escape the common doom; that the minds of its votaries will never look old-fashioned to the grandchildren of the latter? It would be folly to suppose so. Yet if we are to judge by the analogy of the past, when our science once becomes old-fashioned, it will be more for its omissions of fact, for its ignorance of whole ranges and orders of complexity in the phenomena to be explained, than for any fatal lack in its spirit and principles. The spirit and principles of science are mere affairs of method; there is nothing in them that need hinder science from dealing successfully with a world in which personal forces are the starting-point of new effects. The only form of thing that we directly encounter, the only experience that we concretely have, is our own personal life. The only complete category of our thinking, our professors of philosophy tell us, is the category of personality, every other category being one of the abstract elements of that. And this systematic denial on science's part of personality as a condition of events, this rigorous belief that in its own essential and innermost nature our world is a strictly impersonal world, may, conceivably, as the whirligig of time goes round, prove to be the very defect that our descendants will be most surprised at in our own boasted science, the omission that to their eyes will most tend to make it look perspectiveless and short.
 This Essay is formed of portions of an article in Scribner's Magazine for March, 1890, of an article in the Forum for July, 1892, and of the President's Address before the Society for Psychical Research, published in the Proceedings for June, 1896, and in Science.
 Written in 1891. Since then, Mr. Balfour, the present writer, and Professor William Crookes have held the presidential office.
