The Celt in all ages of his long history, like the ancient Greek thinkers with whom his ancestors were contemporary, has always been inclined, unlike modern scientists, to seek an explanation for the phenomena of evolutionary life by postulating a noumenal world of causes as the background of the phenomenal world of effects. To-day, the rapid march of scientific pioneers, chiefly those in psychical research, is bringing our own cold and exact science very close to that indefinable boundary which separates the two worlds; and for that reason alone a presentation of the Celtic theory of the causes operating to produce death and birth will be, at least by way of suggestion, of some value.
Facts of common everyday knowledge are apt to lose their significance through too great familiarity. A fact of this character is that when each child is born it must awaken into life. Often it is not known whether the newly-born babe is dead or alive until it stretches forth its arms and breathes or cries. And this phenomenon of our first awakening and entry upon the visible plane of life and conscious action seems to corroborate what the early Celt who thoughtfully observed it held to be true, and what the Celt of to-day holds to be true: that the material substance composing the body of man is merely a means of expression for life, a conductor for an unknown force which exhibits volition and individual consciousness; just as material substance in a condition called inanimate is a conductor for another unknown force called electricity, which does not exhibit any volition or consciousness. Destroy the human body, and there is no manifestation of its life force; destroy a wire, and there is no manifestation of electric light: the human body seems to be merely incidental in the history of the individual consciousness, as a wire is incidental to electric light.
But is this consciousness of man which we call life simply a phenomenon of matter non-existent without a physical means of expression, or does it—like electricity after the wire is destroyed—continue to exist in an unmanifested state when the human body is cold and motionless in death? And in the case of a child born dead has this consciousness found some organic imperfection in the newly-constructed infant body which made its manifestation impossible? A few thoughts to aid in answering these questions will probably suggest themselves if we briefly consider the great difference between a human body in life and a human body in death. In life, there is the highly organized, delicately adjusted, perfectly balanced human body responding to the will of an invisible power; and it is admitted by all schools of philosophers, moralists, and scientists that this invisible power—whatever it may be—is the real man.
This invisible power, beginning its manifestation through a microscopic bit of germ-plasm, gradually builds for itself a more and more complex physical habitation, until, after the short space of nine months, it claims membership among the ranks of men. During the many years of its sojourn on our planet, it renews its habitation many times. Every atom it began with in childhood is discarded and replaced by a new one long before the age of manhood is reached, and yet upon reaching manhood the invisible power remembers what it did in a child’s frame. This indicates that memory or consciousness as a psychical process does not depend essentially upon a material brain nor upon a certain grouping of ever-changing brain-substance; for if it did, apparently it would slowly and imperceptibly undergo change as completely as the whole physical body and brain. This physiological process furnishes sufficient data to allow us to postulate that there is a psychical organ of memory behind the physical sense-consciousness, and that such an organ in itself is, at least during a human-life period, unchanging in its composition. Without such an organ, the process of memory when more fully analysed (in a way we cannot here attempt) is inexplicable.[608]
The simplest hypothesis is to conceive that organ as the one connected with the subconsciousness or super-sense-consciousness, by means of which the invisible power or rememberer is able to remember and to impress its memory upon the temporary and continually unstable physical brain. In the process of memory there must be first of all a thing to be remembered; second, a record of that thing to be remembered; and third, something to remember that thing. The thing remembered is the result of a conscious experience, the record of it the result of its impress at the time it was experienced, but the rememberer is neither.
That invisible power, which we have called the real man, animates the body, it places food in it as fuel to produce animal heat, animal vitality and force, and tries to keep it in good working order as long as possible. If the body is imperfect at birth or becomes so later, that invisible power is forced to act through it imperfectly; if the brain is diseased, there is insanity, if undeveloped, idiocy; and when the body ceases to respond either perfectly or imperfectly, the invisible power must surrender it entirely, and there is what we call death.
Now what is this invisible power or force which has entirely vanished, leaving the physical body and brain cold and motionless? Let us see if there is an answer. Chemical analysis proves that the visible parts of the body of man are merely transformed gases; but in a complete analysis of a living body such as man’s there are certain elements to be considered which are always invisible.[609] Thus at death there is instantly a cessation of all bodily consciousness—of all willing, thinking, movement. The power which has made the body conscious, and which cannot be compared to any known form of matter, is entirely gone. But there is left in the body a moment after its departure everything which we know to be material—the animal heat, the animal magnetism, the animal vitality. When these are gone, the body is cold and stiff, and in no essential way unlike any other mass of inert matter. If heat be applied to the body, or magnetism, or vital forces, there is nothing in it to retain them any more than there would be in a stone. The real man is gone. Then the body begins to disintegrate. The law of the conservation of energy and the indestructibility of matter makes it certain that in the process of death nothing has been lost, certainly nothing material. The animal heat has gone off somewhere in the atmosphere or in some other matter; the animal magnetism and vitality are momentarily lost sight of, but soon they will be attached to other organic beings such as plants or animals to begin a new cycle of embodiment. The physical constituents of the body will go to their appropriate places, into the air as gases, into the water as fluids, into the earth as salts and minerals, and in a short time may form the parts of a flower, or fruit, or animal. But where or what is the willing, the thinking, the remembering, the directing force which once controlled all these and held them together in unity? Ultra-violet rays are invisible, but they show their existence through their chemical action; similarly a soul or Ego may exist invisibly and show its existence through the vital and physical unity manifested by a living human being. As we have already seen in the preceding chapter, there are a number of the first men of science who feel that when all the data of the latest scientific discoveries in the realm of psychology and of psychical research are impartially examined there is no escape from some such hypothesis as the ancient hypothesis of a soul.
If we accept the soul hypothesis, as it seems we must, and regard a soul as an indestructible unit of invisible power possessing consciousness and volition, and normally able to exist independently of a human body, then it becomes a logical and a scientific necessity to postulate its pre-existence, because as such a unit it is indestructible, in accordance with the law of the conservation of energy and indestructibility of matter. We speak here not of the ordinary soul or human personal consciousness, but of that Ego which Celtic mystics conceive as the permanent principle (though probably itself relative to some still higher power) behind the personality—which, in turn, they believe is a temporary combination wholly dependent upon the Ego. Accordingly, it is scientifically possible for such a soul as a homogeneous unit of force or conscious energy to pass from one mass of matter or physical body to another without disintegration, diminution, or loss of its own identity. It is scientifically certain, also, from experiments performed to test the power of resistance to decomposition exhibited by the force which we call life in an organic body, that such a force is capable of outwearing many physical embodiments.[610] Recent demonstrations tend to show that the heredity hypothesis cannot be held to account fully for such widely varied character or soul individuality as may be exhibited by members of one family. We must therefore account for mental, moral, and certainly psychical inequalities among our race by some other hypothesis; and no hypothesis is more scientific, more in line with known physiological and psychical processes, or more in accord with the law of evolution, than that of re-birth.
The theory of the mechanical transmission of acquired characteristics in a purely physical manner through the germ-plasm is no longer tenable when all the data of physiology and psychology are admitted. A vitalistic view of evolution is rapidly developing in the scientific world, and the weight of evidence is decidedly in favour of regarding all evolutionary processes, reaching from the lowest to the highest organisms, as illustrating a gradual unfolding in the sensuous world of a pre-existing psychical power through an ever-increasing complexity of specialized structures, this complexity being brought about by natural selection. Such a view is also strongly supported if not confirmed by the general scientific belief that spontaneous generation of life is and always has been impossible on our planet or on any planet: there must have been life before its physical manifestation or its physical evolution began.
We may regard this psychical power as like a vast reservoir of consciousness ever trying to force itself through matter, the walls of the reservoir. Through the microscopic body of an amoeba there has percolated a very minute drop from the reservoir. As evolution advances, the walls of the reservoir become more and more porous, and little by little the drop increases to a tiny rivulet. Through the higher animals, the tiny rivulet flows as a brook. Through man as he is, the brook flows as a deep and broad river. Throughout the completely evolved man of the far distant future, the deep and broad river will have overflowed all its banks, it will have inundated and completely overwhelmed the animal-human nature of the individual through whom it flows, as the whole volume of the vast reservoir pours itself out. The ordinary consciousness of man will then have been transmuted into the subconsciousness, of which it had always been a pale reflection. In other words, if the theory of the mechanical transmission of acquired characteristics has failed, as seems to be the case, then we must assume that there is, as the bearer of all gains made from generation to generation, some sort of psychical or vitalistic principle. This, making use of the germ-plasm merely as a physical basis for its manifestation, begins to build up a body suited to its further evolutionary needs.
