We have seen that we can apprehend neither the beginning nor the end of our personality, which comes up out of infinity as an island out of the sea, so gently, that none can say when it is first visible on our mental horizon, and fades away in the case of those who leave offspring, so imperceptibly that none can say when it is out of sight. But, like the island, whether we can see it or no, it is always there. Not only are we infinite as regards time, but we are so also as regards extension, being so linked on to the external world that we cannot say where we either begin or end. If those who so frequently declare that man is a finite creature would point out his boundaries, it might lead to a better understanding.

Nevertheless, we are in the habit of considering that our personality, or soul, no matter where it begins or ends, and no matter what it comprises, is nevertheless a single thing, uncompounded of other souls. Yet there is nothing more certain than that this is not at all the case, but that every individual person is a compound creature, being made up of an infinite number of distinct centres of sensation and will, each one of which is personal, and has a soul and individual existence, a reproductive system, intelligence, and memory of its own, with probably its hopes and fears, its times of scarcity and repletion, and a strong conviction that it is itself the centre of the universe.

True, no one is aware of more than one individuality in his own person at one time. We are, indeed, often greatly influenced by other people, so much so, that we act on many occasions in accordance with their will rather than our own, making our actions answer to their sensations, and register the conclusions of their cerebral action and not our own; for the time being, we become so completely part of them, that we are ready to do things most distasteful and dangerous to us, if they think it for their advantage that we should do so. Thus we sometimes see people become mere processes of their wives or nearest relations. Yet there is a something which blinds us, so that we cannot see how completely we are possessed by the souls which influence us upon these occasions. We still think we are ourselves, and ourselves only, and are as certain as we can be of any fact, that we are single sentient beings, uncompounded of other sentient beings, and that our action is determined by the sole operation of a single will.

But in reality, over and above this possession of our souls by others of our own species, the will of the lower animals often enters into our bodies and possesses them, making us do as they will, and not as we will; as, for example, when people try to drive pigs, or are run away with by a restive horse, or are attacked by a savage animal which masters them. It is absurd to say that a person is a single “ego” when he is in the clutches of a lion. Even when we are alone, and uninfluenced by other people except in so far as we remember their wishes, we yet generally conform to the usages which the current feeling of our peers has taught us to respect; their will having so mastered our original nature, that, do what we may, we can never again separate ourselves and dwell in the isolation of our own single personality. And even though we succeeded in this, and made a clean sweep of every mental influence which had ever been brought to bear upon us, and though at the same time we were alone in some desert where there was neither beast nor bird to attract our attention or in any way influence our action, yet we could not escape the parasites which abound within us; whose action, as every medical man well knows, is often such as to drive men to the commission of grave crimes, or to throw them into convulsions, make lunatics of them, kill them—when but for the existence and course of conduct pursued by these parasites they would have done no wrong to any man.

These parasites—are they part of us or no? Some are plainly not so in any strict sense of the word, yet their action may, in cases which it is unnecessary to detail, affect us so powerfully that we are irresistibly impelled to act in such or such a manner; and yet we are as wholly unconscious of any impulse outside of our own “ego” as though they were part of ourselves; others again are essential to our very existence, as the corpuscles of the blood, which the best authorities concur in supposing to be composed of an infinite number of living souls, on whose welfare the healthy condition of our blood, and hence of our whole bodies, depends. We breathe that they may breathe, not that we may do so; we only care about oxygen in so far as the infinitely small beings which course up and down in our veins care about it: the whole arrangement and mechanism of our lungs may be our doing, but is for their convenience, and they only serve us because it suits their purpose to do so, as long as we serve them. Who shall draw the line between the parasites which are part of us, and the parasites which are not part of us? Or again, between the influence of those parasites which are within us, but are yet not us, and the external influence of other sentient beings and our fellow-men? There is no line possible. Everything melts away into everything else; there are no hard edges; it is only from a little distance that we see the effect as of individual features and existences. When we go close up, there is nothing but a blur and confused mass of apparently meaningless touches, as in a picture by Turner.

The following passage from Mr. Darwin’s provisional theory of Pangenesis, will sufficiently show that the above is no strange and paradoxical view put forward wantonly, but that it follows as a matter of course from the conclusions arrived at by those who are acknowledged leaders in the scientific world. Mr. Darwin writes thus:—

The functional independence of the elements or units of the body.—Physiologists agree that the whole organism consists of a multitude of elemental parts, which are to a great extent independent of one another. Each organ, says Claude Bernard, has its proper life, its autonomy; it can develop and reproduce itself independently of the adjoining tissues. A great German authority, Virchow, asserts still more emphatically that each system consists of ‘an enormous mass of minute centres of action. . . . Every element has its own special action, and even though it derive its stimulus to activity from other parts, yet alone effects the actual performance of duties. . . . Every single epithelial and muscular fibre-cell leads a sort of parasitical existence in relation to the rest of the body. . . . Every single bone corpuscle really possesses conditions of nutrition peculiar to itself.’ Each element, as Sir J. Paget remarks, lives its appointed time, and then dies, and is replaced after being cast off and absorbed. I presume that no physiologist doubts that, for instance, each bone corpuscle of the finger differs from the corresponding corpuscle of the corresponding joint of the toe,” &c., &c. (“Plants and Animals under Domestication,” vol. ii. pp. 364, 365, ed. 1875).

In a work on heredity by M. Ribot, I find him saying, “Some recent authors attribute a memory” (and if so, surely every attribute of complete individuality) “to every organic element of the body;” among them Dr. Maudsley, who is quoted by M. Ribot, as saying, “The permanent effects of a particular virus, such as that of the variola, in the constitution, shows that the organic element remembers for the remainder of its life certain modifications it has received. The manner in which a cicatrix in a child’s finger grows with the growth of the body, proves, as has been shown by Paget, that the organic element of the part does not forget the impression it has received. What has been said about the different nervous centres of the body demonstrates the existence of a memory in the nerve cells diffused through the heart and intestines; in those of the spinal cord, in the cells of the motor ganglia, and in the cells of the cortical substance of the cerebal hemispheres.”

Now, if words have any meaning at all, it must follow from the passages quoted above, that each cell in the human body is a person with an intelligent soul, of a low class, perhaps, but still differing from our own more complex soul in degree, and not in kind; and, like ourselves, being born, living, and dying. So that each single creature, whether man or beast, proves to be as a ray of white light, which, though single, is compounded of the red, blue, and yellow rays. It would appear, then, as though “we,” “our souls,” or “selves,” or “personalities,” or by whatever name we may prefer to be called, are but the consensus and full flowing stream of countless sensations and impulses on the part of our tributary souls or “selves,” who probably know no more that we exist, and that they exist as part of us, than a microscopic water-flea knows the results of spectrum analysis, or than an agricultural labourer knows the working of the British constitution: and of whom we know no more, until some misconduct on our part, or some confusion of ideas on theirs, has driven them into insurrection, than we do of the habits and feelings of some class widely separated from our own.

These component souls are of many and very different natures, living in territories which are to them vast continents, and rivers, and seas, but which are yet only the bodies of our other component souls; coral reefs and sponge-beds within us; the animal itself being a kind of mean proportional between its house and its soul, and none being able to say where house ends and animal begins, more than they can say where animal ends and soul begins. For our bones within us are but inside walls and buttresses, that is to say, houses constructed of lime and stone, as it were, by coral insects; and our houses without us are but outside bones, a kind of exterior skeleton or shell, so that we perish of cold if permanently and suddenly deprived of the coverings which warm us and cherish us, as the wing of a hen cherishes her chickens. If we consider the shells of many living creatures, we shall find it hard to say whether they are rather houses, or part of the animal itself, being, as they are, inseparable from the animal, without the destruction of its personality.
