which the patient drops suddenly to the floor with loss of consciousness, and quite as suddenly rises again in full possession of his faculties. I have watched such cases for hours, and always with increasing marvel. The loss of consciousness is complete, and often lasts but a fraction of a second. How account for such phenomenon! If consciousness were a diffused attribute of the whole brain, what spasm of blood-vessels or other physical process familiar to us could act and be adjusted with such speed? If, however, the 'seat' of consciousness be limited to some very small portion of the brain, some physical process such as is suggested could easily account for the instantaneous loss and regaining of consciousness."
Other facts in support of this theory are given, and the statement of Dr. C. L. Dana that, in poisoning by illuminating gas, the chief symptom is loss of consciousness, and the only lesion discovered is softening of the corpora striata; then the following:
"Assuming now that it were proved that the power which creates consciousness has some definite seat, and that it is a summation of energies physiologically varying in sleep and waking, which may be directed to any part of our store of experiences for purposes of illumination, what portion of the brain is so constructed as to be in apparently intimate connection with every other? The corpora striata! … There is no portion of the brain we know so little of. … Here we have a portion of the brain which must be of enormous significance, otherwise it would not be always present, from the fish up to man."
It will be seen that Dr. Peterson is here opposed to the doctrine maintained by both Lotze[5] and MacDougall,[6] who both maintained that: "There are a number of separate points in the brain which form so many 'seats' of the soul. Each of these would be of equal value with the rest; at each of them the soul would be present with equal completeness." But whether there be one or several "seats" of consciousness, it is obvious that there must be contact of some sort, at one or several points (granting the correctness of the theory that spirit acts upon matter at all), and the question is: How may this action be supposed to take place?
In discussing this question in a former book[7] I said:
"It is more than probable, it seems to me, that there exists some sort of etheric medium between mind and even organic nervous tissue, upon which the mind must act first of all. Thus, we should have the chain of connection: mind, vital or etheric medium, nervous tissue, muscle, bone. So mind acts upon matter; and it will be seen that there is an increasing density of structure, and that just in proportion to this density is mind incapable of affecting matter directly. We must, it seems to me, always postulate some sort of etheric medium through which mind acts, in order to affect and move matter—organic or inorganic. And without this vital intermediary there can be no action, and consequently no manifestation."
Now, it would appear rational to suppose that some action of this sort takes place when mind acts upon, or influences, matter. Air is invisible, and practically imperceptible to our senses—when stationary. But set into motion, a current of air will close a door with a bang—will have the effect of definitely moving a heavy mass of inanimate matter, in the manner indicated. It may be that in somewhat the same way mind affects brain. Mind may reside in a sort of etheric vehicle, and be more or less stable or stationary, save at the times when volition or intense, active conscious operations are in progress—when, in short, effort is exerted. At such times, it is surely conceivable that what was static becomes dynamic; something is set into motion which in turn brings into activity some more "physical" energy, and so on, until sufficient material momentum has been gained to affect that most unstable and mobile substance, nervous tissue. It is certainly quite conceivable that certain nervous centres in the brain (which centres, we cannot say) might be set into actual operation by some such process; or at least that the impulse or energy supplied in this manner might be sufficient to release the nervous energy stored in the cell, much as the trigger of a rifle would, when pressed, release the energy contained within the cartridge. Such "hair trigger" action has been postulated by both William James and Bergson, and is certainly in line with modern speculations in this direction. There are also certain analogies to be drawn from physical science to guide us here.
In electricity, e.g., what are known as "relays" are constantly employed, and beautifully illustrate the principle here outlined. In working over long lines, or where there are a number of instruments in one circuit, the currents are often not strong enough to work the recording instruments directly. In such a case there is interposed a "relay" or "repeater." This instrument consists of an electro-magnet round which the line current flows, and whose delicately-poised armature, when attracted, makes contact for a local circuit, in which a local battery and the receiving Morse instrument (sounder, writer, etc.) are included. The principle of the relay is, then, that a current too weak to do the work itself may get a strong local current to do its work for it.
It may be the same in the case of mental action. Volition or thought may be too weak, per se, to influence nervous processes; but, when exceptionally active or potent, they may set into activity specific nerve energies which manifest in the manner known to us as motor and physical phenomena. Here is, it seems to me, a rational explanation of the facts, and one which is in accord, not only with ordinary psychological phenomena, but with those more puzzling and obscure manifestations witnessed from time to time in psychic research.
13. It may be objected that such a conception of the facts supposes that will (and conscious thought) are physical energies—for however slight we make this energy, it is still energy none the less. The air which closed the door would not move it of itself—unless some pressure were exerted upon it from without. Could "life" act otherwise?
One reply to this objection is that the distinguishing characteristic of life is this very power of original, spontaneous movement. It is life, and life alone, which possesses this power. Were this doctrine true, it would of course upset the present theory of the Conservation of Energy, for it would admit the constant infusion into the world of energy from without. Despite the theoretical difficulty thus presented, it seems probable that life is, in a certain sense, a physical energy, or at least its manifestation is. It is possible that the two states are similar to the difference between potential and kinetic energy; and we must remember that energy is always noticed or experienced by us, as energy, in its expenditure, never in its accumulation.[8]
If life be a physical force, if vitality be a specific energy, then, it seems to me, many things fall into line—many phenomena, hitherto inexplicable, become at once intelligible.
Let me illustrate this conclusion by mentioning a few such facts:
Take, for instance, the phenomena manifested in the presence of Eusapia Palladino. I shall not now stop to discuss the reality of these manifestations, because I consider them just as certain as any other facts in life, and not at all open to discussion. Now, in these phenomena there is an intelligence of some sort at work producing them; that is certain. But as to the nature of this intelligence—what it is—that is altogether another matter, and a much more difficult question to answer. Whether this be a low order of deceiving and "lying spirits," as Professor Barrett and others are apparently inclined to believe, or whether it be a fraction of the medium's own mind (Flournoy, Morselli), or whether it be the spirit it claims to be, or whether it belongs to some other even more doubtful order of intelligence, such as postulated by the Theosophists and certain Mystics and Occultists, that is a question which we cannot at present answer, and for which we may have to wait for several hundred years before one can be satisfactorily given.
But, granting the reality of the phenomena, they themselves demand solution, solely from the point of view of physics and physiology, and quite aside from the nature of the intelligence with which they are at times associated. The facts themselves still need elucidation.
Some years ago a gentleman of my acquaintance started out with the intention of constructing a telephone by means of which it would be possible to speak directly to the spirit world! He had in mind great delicacy of apparatus, a system of "relays," by means of which it would be possible to augment an initial stimulus, however slight, a magnifying apparatus which would greatly increase the volume of sound, on the lines of the ampliphone and the microphone, etc. I do not believe that very definite results were ever achieved, and he is still at work upon the problem. Needless to say,
