The reader who may feel disposed to give his adhesion to this culminating group of the long series of evidences which have pointed with more and more clearness to the survival of human personality, and to the possibility for men on earth of actual commerce with a world beyond, may feel perhaps that the desiderium orbis catholici, the intimate and universal hope of every generation of men, has never till this day approached so near to fulfilment. There has never been so fair a prospect for Life and Love. But the goal to which we tend is not an ideal of personal happiness alone. The anticipation of our own future is but one element in the prospect which opens to us now. Our inquiry has broadened into a wider scope. The point from which we started was an analysis of the latent faculties of man. The point towards which our argument has carried us is the existence of a spiritual environment in which those faculties operate, and of unseen neighbours who speak to us thence with slowly gathering power. Deep in this spiritual environment the cosmic secret lies. It is our business to collect the smallest indications; to carry out from this treasury of Rhampsinitus so much as our bare hands can steal away. We have won our scraps of spiritual experience, our messages from behind the veil; we can try them in their connection with certain enigmas which philosophy hardly hoped to be able to put to proof. Can we, for instance, learn anything,—to begin with fundamental problems,—of the relation of spiritual phenomena to Space, to Time, to the material world?
As to the idea of Space, the evidence which will have been presented will enable us to speak with perhaps more clearness than could have been hoped for in such a matter. Spiritual life, we infer, is not bound and confined by space-considerations in the same way as the life of earth. But in what way is that greater freedom attained? It appears to be attained by the mere extension of certain licenses (so to call them) permitted to ourselves. We on earth submit to two familiar laws of the ordinary material universe. A body can only act where it is. Only one body can occupy the same part of space at the same moment. Applied to common affairs these rules are of plain construction. But once get beyond ponderable matter,—once bring life and ether into play, and definitions become difficult indeed. The orator, the poet, we say, can only act where he is;—but where is he? He has transformed the sheet of paper into a spiritual agency;—nay, the mere memory of him persists as a source of energy in other minds. Again, we may say that no other body can be in the same place as this writing-table; but what of the ether? What we have thus far learnt of spiritual operation seems merely to extend these two possibilities. Telepathy indefinitely extends the range of an unembodied spirit's potential presence. The interpenetration of the spiritual with the material environment leaves this ponderable planet unable to check or to hamper spiritual presence or operation. Strange and new though our evidence may be, it needs at present in its relation to space nothing more than an immense extension of conceptions which the disappearance of earthly limitations was certain immensely to extend.
How, then, does the matter stand with regard to our relation to Time? Do we find that our new phenomena point to any mode of understanding or of transcending Time fundamentally different from those modes which we have at our command?
In dealing with Time Past we have memory and written record; in dealing with Time Future we have forethought, drawing inferences from the past.
Can, then, the spiritual knowledge of Past and Future which our evidence shows be explained by assuming that these existing means of knowledge are raised to a higher power? Or are we driven to postulate something in the nature of Time which is to us inconceivable;—some co-existence of Past and Future in an eternal Now? It is plainly with Time Past that we must begin the inquiry.
The knowledge of the past which automatic communications manifest is in most cases apparently referable to the actual memory of persons still existing beyond the tomb. It reaches us telepathically, as from a mind in which remote scenes are still imprinted. But there are certain scenes which are not easily assigned to the individual memory of any given spirit. And if it be possible for us to learn of present facts by telæsthesia as well as by telepathy;—by some direct supernormal percipience without the intervention of any other mind to which the facts are already known,—may there not be also a retrocognitive telæsthesia by which we may attain a direct knowledge of facts in the past?
Some conception of this kind may possibly come nearest to the truth. It may even be that some World-Soul is perennially conscious of all its past; and that individual souls, as they enter into deeper consciousness, enter into something which is at once reminiscence and actuality. But nevertheless a narrower hypothesis will cover the actual cases with which we have to deal. Past facts are known to men on earth not from memory only, but by written record; and there may be records, of what kind we know not, which persist in the spiritual world. Our retrocognitions seem often a recovery of isolated fragments of thought and feeling, pebbles still hard and rounded amid the indecipherable sands over which the mighty waters are "rolling evermore."
When we look from Time Past to Time Future we are confronted with essentially the same problems, though in a still more perplexing form, and with the world-old mystery of Free Will versus Necessity looming in the background. Again we find that, just as individual memory would serve to explain a large proportion of Retrocognition, so individual forethought—a subliminal forethought, based often on profound organic facts not normally known to us—will explain a large proportion of Precognition. But here again we find also precognitions which transcend what seems explicable by the foresight of any mind such as we know; and we are tempted to dream of a World-Soul whose Future is as present to it as its Past. But in this speculation also, so vast and vague an explanation seems for the present beyond our needs; and it is safer—if aught be safe in this region which only actual evidence could have emboldened us to approach—to take refuge in the conception of intelligences not infinite, yet gifted with a foresight which strangely transcends our own.
Closely allied to speculations such as these is another speculation, more capable of subjection to experimental test, yet which remains still inconclusively tested, and which has become for many reasons a stumbling-block rather than a corroboration in the spiritual inquiry. I refer to the question whether any influence is exercised by spirits upon the gross material world otherwise than through ordinary organic structures. We know that the spirit of a living man controls his own organism, and we shall see reason to conclude that discarnate spirits may also control, by some form of "possession," the organisms of living persons,—may affect directly, that is to say, some portions of matter which we call living, namely, the brain of the entranced sensitive. There seems to me, then, no paradox in the supposition that some effect should be produced by spiritual agency—possibly through the mediation of some kind of energy derived from living human beings—upon inanimate matter as well. And I believe that as a fact such effects have been observed and recorded in a trustworthy manner by Sir W. Crookes, the late Dr. Speer, and others, in the cases especially of D. D. Home and of W. Stainton Moses. If, indeed, I call these and certain other records still inconclusive, it is mainly on account of the mass of worthless narratives with which they have been in some sense smothered; the long history of so-called investigations which have consisted merely in an interchange of credulity and fraud. For the present the evidence of this kind which has real value is better presented, I think, in separate records than collected or discussed in any generalised form. All that I purpose in this work, therefore, is briefly to indicate the relation which these "physical phenomena" hold to the psychical phenomena with which my book is concerned. Alongside of the faculty or achievement of man's ordinary or supraliminal self I shall demarcate the faculty or achievement which I ascribe to his subliminal self; and alongside of this again I shall arrange such few well-attested phenomena as seem primâ facie to demand the physical intervention of discarnate intelligences.
I have traced the utmost limits to which any claim to a scientific basis for these inquiries can at present be pushed. Yet the subject-matter has not yet been exhausted of half its significance. The conclusions to which our evidence points are not such as can be discussed or dismissed as a mere matter of speculative curiosity. They affect every belief, every faculty, every hope and aim of man; and they affect him the more intimately as his interests grow more profound. Whatever meaning be applied to ethics, to philosophy, to religion, the concern of all these is here.
