I may be mistaken in the impression I have derived from the paragraphs I have quoted. I commonly say they give me the impression that I have tried to convey to the reader, i.e., that the writer’s assent to anything like intelligence, or consciousness of needs, an animal low down in the scale of life, is grudging, and that he is more comfortable when he has got hold of onto to which he can point and say that mere, at any rate, is an unintelligent and merely instinctive creature. I have only called attention to the passage as an example of the intellectual bias of a large number of exceedingly able and thoughtful persons, among whom, so far as I am able to form an opinion at all, few have greater claims to our respectful attention than Dr. Carpenter himself.
For the embryo of a chicken, then, we damn exactly the same kind of reasoning power and contrivance which we damn for the amœba, or for our own intelligent performances in later life. We do not claim for it much, if any, perception of its own forethought, for we know very well that it is among the most prominent features of intellectual activity that, after a number of repetitions, it ceases to be perceived, and that it does not, in ordinary cases, cease to be perceived till after a very great number of repetitions. The fact that the embryo chicken makes itself always as nearly as may be in the same way, would lead us to suppose that it would be unconscious of much of its own action, provided it were always the same chicken which made itself over and over again. So far we can see, it always is unconscious of the greater part of its own wonderful performance. Surely then we have a presumption that it is the same chicken which makes itself over and over again; for such unconsciousness is not won, so far as our experience goes, by any other means than by frequent repetition of the same act on the part of one and the same individual. How this can be we shall perceive in subsequent chapters. In the meantime, we may say that all knowledge and volition would seem to be merely parts of the knowledge and volition of the primordial cell (whatever this may be), which slumbers but never dies—which has grown, and multiplied, and differentiated itself into the compound life of the womb, and which never becomes conscious of knowing what it has once learnt effectually, till it is for some reason on the point of, or in danger of, forgetting it.
The action, therefore, of an embryo making its way up in the world from a simple cell to a baby, developing for itself eyes, ears, hands, and feet while yet unborn, proves to be exactly of one and the same kind as that of a man of fifty who goes into the City and tells his broker to buy him so many Great Northern A shares—that is to say, an effort of the will exercised in due course on a balance of considerations as to the immediate expediency, and guided by past experience; while children who do not reach birth are but prenatal spendthrifts, ne’er-do-weels, inconsiderate innovators, the unfortunate in business, either through their own fault or that of others, or through inevitable mischances, beings who are culled out before birth instead of after; so that even the lowest idiot, the most contemptible in health or beauty, may yet reflect with pride that they were born. Certainly we observe that those who have had good fortune (mother and sole cause of virtue, and sole virtue in itself), and have profited by their experience, and known their business best before birth, so that they made themselves both to be and to look well, do commonly on an average prove to know it best in after-life: they grow their clothes best who have grown their limbs best. It is rare that those who have not remembered how to finish their own bodies fairly well should finish anything well in later life. But how small is the addition to their unconscious attainments which even the Titans of human intellect have consciously accomplished, in comparison with the problems solved by the meanest baby living, nay, even by one whose birth is untimely! In other words, how vast is that back knowledge over which we have gone fast asleep, through the prosiness of perpetual repetition; and how little in comparison, is that whose novelty keeps it still within the scope of our conscious perception! What is the discovery of the laws of gravitation as compared with the knowledge which sleeps in every hen’s egg upon a kitchen shelf?
It is all a matter of habit and fashion. Thus we see kings and councillors of the earth admired for facing death before what they are pleased to call dishonour. If, on being required to go without anything they have been accustomed to, or to change their habits, or do what is unusual in the case of other kings under like circumstances, then, if they but fold their cloak decently around them, and die upon the spot of shame at having had it even required of them to do thus or thus, then are they kings indeed, of old race, that know their business from generation to generation. Or if, we will say, a prince, on having his dinner brought to him ill-cooked, were to feel the indignity so keenly as that he should turn his face to the wall, and breathe out his wounded soul in one sigh, do we not admire him as a “real prince,” who knows the business of princes so well that he can conceive of nothing foreign to it in connection with himself, the bare effort to realise a state of things other than what princes have been accustomed to being immediately fatal to him? Yet is there no less than this in the demise of every half-hatched hen’s egg, shaken rudely by a schoolboy, or neglected by a truant mother; for surely the prince would not die if he knew how to do otherwise, and the hen’s egg only dies of being required to do something to which it is not accustomed.
But the further consideration of this and other like reflections would too long detain us. Suffice it that we have established the position that all living creatures which show any signs of intelligence, must certainly each one have already gone through the embryonic stages an infinite number of times, or they could no more have achieved the intricate process of self-development unconsciously, than they could play the piano unconsciously without any previous knowledge of the instrument. It remains, therefore, to show the when and where of their having done so, and this leads us naturally to the subject of the following chapter—Personal Identity.
CHAPTER V.
PERSONAL IDENTITY.
“Strange difficulties have been raised by some,” says Bishop Butler, “concerning personal identity, or the sameness of living agents as implied in the notion of our existing now and hereafter, or indeed in any two consecutive moments.” But in truth it is not easy to see the strangeness of the difficulty, if the words either “personal” or “identity” are used in any strictness.
Personality is one of those ideas with which we are so familiar that we have lost sight of the foundations upon which it rests. We regard our personality as a simple definite whole; as a plain, palpable, individual thing, which can be seen going about the streets or sitting indoors at home, which lasts us our lifetime, and about the confines of which no doubt can exist in the minds of reasonable people. But in truth this “we,” which looks so simple and definite, is a nebulous and indefinable aggregation of many component parts which war not a little among themselves, our perception of our existence at all being perhaps due to this very clash of warfare, as our sense of sound and light is due to the jarring of vibrations. Moreover, as the component parts of our identity change from moment to moment, our personality becomes a thing dependent upon the present, which has no logical existence, but lives only upon the sufferance of times past and future, slipping out of our hands into the domain of one or other of these two claimants the moment we try to apprehend it. And not only is our personality as fleeting as the present moment, but the parts which compose it blend some of them so imperceptibly into, and are so inextricably linked on to, outside things which clearly form no part of our personality, that when we try to bring ourselves to book, and determine wherein we consist, or to draw a line as to where we begin or end, we find ourselves completely baffled. There is nothing but fusion and confusion.
Putting theology on one side, and dealing only with the common daily experience of mankind, our body is certainly part of our personality. With the destruction of our bodies, our personality, as far as we can follow it, comes to a full stop; and with every modification of them it is correspondingly modified. But what are the limits of our bodies? They are composed of parts, some of them so unessential as to be hardly included in personality at all, and to be separable from ourselves without perceptible effect, as the hair, nails, and daily waste of tissue. Again, other parts are very important, as our hands, feet, arms, legs, &c., but still are no essential parts of our “self” or “soul,” which continues to exist in spite of their amputation. Other parts, as the brain, heart, and blood, are so essential that they cannot be dispensed with, yet it is impossible to say that personality consists in any one of them.
Each one of these component members of our personality is continually dying and being born again, supported in this process by the food we eat, the water we drink, and the air we breathe; which three things link us on, and fetter us down, to the organic and inorganic world about us. For our meat and drink, though no part of our personality before we eat and drink, cannot, after we have done so, be separated entirely from us without the destruction of our personality altogether, so far as we can follow it; and who shall say at what precise moment our food has or has not become part of ourselves? A famished man eats food; after a short time his whole personality is so palpably affected that we know the food to have entered into him and taken, as it were, possession of him; but who can say at what precise moment it did so? Thus we find that we are rooted into outside things and melt away into them, nor can any man say he consists absolutely in this or that, nor define himself so certainly as to include neither more nor less than himself; many undoubted parts of his personality being more separable from it, and changing it less when so separated, both to his own senses and those of other people, than other parts which are strictly speaking no parts at all.
