Chapter 8

But given the practice or experience, and the intricacy of the process to be performed appears to matter very little. There is hardly anything conceivable as being done by man, which a certain amount of familiarity will not enable him to do, unintrospectively, and without conscious effort. "The most complex and difficult movements," writes Mr. Darwin, "can in time be performed without the least effort or consciousness." All the main business of life is done thus unconsciously or semi-unconsciously. For what is the main business of life? We work that we may eat and digest, rather than eat and digest that we may work; this, at any rate, is the normal state of things; the more important business then is that which is carried on unconsciously. So again, the action of the brain, which goes on prior to our realising the idea in which it results, is not perceived by the individual. So also all the deeper springs of action and conviction. The residuum with which we fret and worry ourselves is a mere matter of detail, as the higgling and haggling of the market, which is not over the bulk of the price, but over the last halfpenny.

Shall we say, then, that a baby of a day old sucks (which involves the whole principle of the pump, and hence a profound practical knowledge of the laws of pneumatics and hydrostatics), digests, oxygenises its blood (millions of years before Sir Humphry Davy discovered oxygen), sees and hears--all most difficult and complicated operations, involving an unconscious knowledge of the facts concerning optics and acoustics, compared with which the conscious discoveries of Newton sink into utter insignificance? Shall we say that a baby can do all these things at once, doing them so well and so regularly, without being even able to direct its attention to them, and without mistake, and at the same time not know how to do them, and never have done them before?

Such an assertion would be a contradiction to the whole experience of mankind. Surely the _onus probandi_ must rest with him who makes it.

A man may make a lucky hit now and again by what is called a fluke, but even this must be only a little in advance of his other performances of the same kind. He may multiply seven by eight by a fluke after a little study of the multiplication table, but he will not be able to extract the cube root of 4913 by a fluke, without long training in arithmetic, any more than an agricultural labourer would be able to operate successfully for cataract. If, then, a grown man cannot perform so simple an operation as that, we will say, for cataract, unless he have been long trained in other similar operations, and until he has done what comes to the same thing many times over, with what show of reason can we maintain that one who is so far less capable than a grown man, can perform such vastly more difficult operations, without knowing how to do them, and without ever having done them before? There is no sign of "fluke" about the circulation of a baby's blood. There may perhaps be some little hesitation about its earliest breathing, but this, as a general rule, soon passes over, both breathing and circulation, within an hour after birth, being as regular and easy as at any time during life. Is it reasonable, then, to say that the baby does these things without knowing how to do them, and without ever having done them before, and continues to do them by a series of lifelong flukes?

It would be well if those who feel inclined to hazard such an assertion would find some other instances of intricate processes gone through by people who know nothing about them, and who never had any practice therein. What _is_ to know how to do a thing? Surely to do it. What is proof that we know how to do a thing? Surely the fact that we can do it. A man shows that he knows how to throw the boomerang by throwing the boomerang. No amount of talking or writing can get over this; _ipso facto_, that a baby breathes and makes its blood circulate, it knows how to do so; and the fact that it does not know its own knowledge is only proof of the perfection of that knowledge, and of the vast number of past occasions on which it must have been exercised already. As has been said already, it is less obvious when the baby could have gained its experience, so as to be able so readily to remember exactly what to do; _but it is more easy to suppose that the necessary occasions cannot have been wanting_, _than that the power which we observe_, _should have been obtained without practice and memory_.

If we saw any self-consciousness on the baby's part about its breathing or circulation, we might suspect that it had had less experience, or had profited less by its experience, than its neighbours--exactly in the same manner as we suspect a deficiency of any quality which we see a man inclined to parade. We all become introspective when we find that we do not know our business, and whenever we are introspective we may generally suspect that we are on the verge of unproficiency. Unfortunately, in the case of sickly children we observe that they sometimes do become conscious of their breathing and circulation, just as in later life we become conscious that we have a liver or a digestion. In that case there is always something wrong. The baby that becomes aware of its breathing does not know how to breathe and will suffer for his ignorance and incapacity, exactly in the same way as he will suffer in later life for ignorance and incapacity in any other respect in which his peers are commonly knowing and capable. In the case of inability to breathe, the punishment is corporal, breathing being a matter of fashion, so old and long settled that nature can admit of no departure from the established custom, and the procedure in case of failure is as much formulated as the fashion itself. In the case of the circulation, the whole performance has become one so utterly of rote, that the mere discovery that we could do it at all was considered one of the highest flights of human genius.

It has been said a day will come when the Polar ice shall have accumulated, till it forms vast continents many thousands of feet above the level of the sea, all of solid ice. The weight of this mass will, it is believed, cause the world to topple over on its axis, so that the earth will be upset as an ant-heap overturned by a ploughshare. In that day the icebergs will come crunching against our proudest cities, razing them from off the face of the earth as though they were made of rotten blotting-paper. There is no respect now of Handel nor of Shakespeare; the works of Rembrandt and Bellini fossilise at the bottom of the sea. Grace, beauty, and wit, all that is precious in music, literature, and art--all gone. In the morning there was Europe. In the evening there are no more populous cities nor busy hum of men, but a sea of jagged ice, a lurid sunset, and the doom of many ages. Then shall a scared remnant escape in places, and settle upon the changed continent when the waters have subsided--a simple people, busy hunting shellfish on the drying ocean beds, and with little time for introspection; yet they can read and write and sum, for by that time these accomplishments will have become universal, and will be acquired as easily as we now learn to talk; but they do so as a matter of course, and without self-consciousness. Also they make the simpler kinds of machinery too easily to be able to follow their own operations--the manner of their own apprenticeship being to them as a buried city. May we not imagine that, after the lapse of another ten thousand years or so, some one of them may again become cursed with lust of introspection, and a second Harvey may astonish the world by discovering that it can read and write, and that steam-engines do not grow, but are made? It may be safely prophesied that he will die a martyr, and be honoured in the fourth generation.

PERSONAL IDENTITY. (CHAPTER V. OF LIFE AND HABIT.)

"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; as something 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 time 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 baffled. There is nothing but fusion and confusion.

Putting theology on one side, and dealing only with the common sense 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 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, though in a modified condition, 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 melt away into outside things and are rooted into them as plants into the soil in which they grow, 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.

A man's clothes, for example, as they lie on a chair at night are no part of him, but when he wears them they would appear to be so, as being a kind of food which warms him and hatches him, and the loss of which may kill him of cold. If this be denied, and a man's clothes be considered as no part of his self, nevertheless they, with his money, and it may perhaps be added his religious opinions, stamp a man's individuality as strongly as any natural feature can stamp it. Change in style of dress, gain or loss of money, make a man feel and appear more changed than having his chin shaved or his nails cut. In fact, as soon as we leave common parlance on one side, and try for a scientific definition of personality, we find that there is none possible, any more than there can be a demonstration of the fact that we exist at all--a demonstration for which, as for that of a personal God, many have hunted but which none have found. The only solid foundation is, as in the case of the earth's crust, pretty near the surface of things; the deeper we try to go, the damper, darker, and altogether more uncongenial we find it. There is no quagmire of superstition into which we may not be easily lured if we once cut ourselves adrift from those superficial aspects of things, in which alone our nature permits us to be comforted.

Common parlance, however, settles the difficulty readily enough (as indeed it settles most others if they show signs of awkwardness) by the simple process of ignoring it: we decline, and very properly, to go into the question of where personality begins and ends, but assume it to be known by every one, and throw the onus of not knowing it upon the over- curious, who had better think as their neighbours do, right or wrong, or there is no knowing into what villany they may not presently fall.

Assuming, then, that every one knows what is meant by the word "person" (and such superstitious bases as this are the foundations upon which all action, whether of man, beast, or plant, is constructed and rendered possible; for even the corn in the fields grows upon a superstitious basis as to its own existence, and only turns the earth and moisture into wheat through the conceit of its own ability to do so, without which faith it were powerless; and the lichen only grows upon the granite rock by first saying to itself, "I think I can do it;" so that it would not be able to grow unless it thought it could grow, and would not think it could grow unless it found itself able to grow, and thus spends its life arguing most virtuously in a most vicious circle--basing action upon hypothesis, which hypothesis is in turn based upon action)--assuming that we know what is meant by the word "person," we say that we are one and the same person from birth till death, so that whatever is done by or happens to any one between birth and death, is said to happen to or be done by one individual. This in practice is found sufficient for the law courts and the purposes of daily life, which, being full of hurry and the pressure of business, can only tolerate compromise, or conventional rendering of intricate phenomena. When facts of extreme complexity have to be daily and hourly dealt with by people whose time is money, they must be simplified, and treated much as a painter treats them, drawing them in squarely, seizing the more important features, and neglecting all that does not assert itself as too essential to be passed over--hence the slang and cant words of every profession, and indeed all language; for language at best is but a kind of "patter," the only way, it is true, in many cases, of expressing our ideas to one another, but still a very bad way, and not for one moment comparable to the unspoken speech which we may sometimes have recourse to. The metaphors and _facons de parler_ to which even in the plainest speech we are perpetually recurring (as, for example, in this last two lines, "plain," "perpetually," and "recurring," are all words based on metaphor, and hence more or less liable to mislead) often deceive us, as though there were nothing more than what we see and say, and as though words, instead of being, as they are, the creatures of our convenience, had some claim to be the actual ideas themselves concerning which we are conversing.

This is so well expressed in a letter I have recently received from a friend, now in New Zealand, and certainly not intended by him for publication, that I shall venture to quote the passage, but should say that I do so without his knowledge or permission which I should not be able to receive before this book must be completed.

"Words, words, words," he writes, "are the stumbling-blocks in the way of truth. Until you think of things as they are, and not of the words that misrepresent them, you cannot think rightly. Words produce the appearance of hard and fast lines where there are none. Words divide; thus we call this a man, that an ape, that a monkey, while they are all only differentiations of the same thing. To think of a thing they must be got rid of: they are the clothes that thoughts wear--only the clothes. I say this over and over again, for there is nothing of more importance. Other men's words will stop you at the beginning of an investigation. A man may play with words all his life, arranging them and rearranging them like dominoes. If I could _think_ to you without words you would understand me better."

If such remarks as the above hold good at all, they do so with the words "personal identity." The least reflection will show that personal identity in any sort of strictness is an impossibility. The expression is one of the many ways in which we are obliged to scamp our thoughts through pressure of other business which pays us better. For surely all reasonable people will feel that an infant an hour before birth, when in the eye of the law he has no existence, and could not be called a peer for another sixty minutes, though his father were a peer, and already dead,--surely such an embryo is more personally identical with the baby into which he develops within an hour's time than the born baby is so with itself (if the expression may be pardoned), one, twenty, or it may be eighty years after birth. There is more sameness of matter; there are fewer differences of any kind perceptible by a third person; there is more sense of continuity on the part of the person himself, and far more of all that goes to make up our sense of sameness of personality between an embryo an hour before birth and the child on being born, than there is between the child just born and the man of twenty. Yet there is no hesitation about admitting sameness of personality between these two last.

On the other hand, if that hazy contradiction in terms, "personal identity," be once allowed to retreat behind the threshold of the womb, it has eluded us once for all. What is true of one hour before birth is true of two, and so on till we get back to the impregnate ovum, which may fairly claim to have been personally identical with the man of eighty into which it ultimately developed, in spite of the fact that there is no particle of same matter nor sense of continuity between them, nor recognised community of instinct, nor indeed of anything which on a _prima facie_ view of the matter goes to the making up of that which we call identity.

There is far more of all these things common to the impregnate ovum and the ovum immediately before impregnation, or again between the impregnate ovum, and both the ovum before impregnation and the spermatozoon which impregnated it. Nor, if we admit personal identity between the ovum and the octogenarian, is there any sufficient reason why we should not admit it between the impregnate ovum and the two factors of which it is composed, which two factors are but offshoots from two distinct personalities, of which they are as much part as the apple is of the apple-tree; so that an impregnate ovum cannot without a violation of first principles be debarred from claiming personal identity with both its parents, and hence, by an easy chain of reasoning, _with each of the impregnate ova from which its parents were developed_.

So that each ovum when impregnate should be considered not as descended from its ancestors, but as being a continuation of the personality of every ovum in the chain of its ancestry, every which ovum _it actually is_ as truly as the octogenarian _is_ the same identity with the ovum from which he has been developed. The two cases stand or fall together.

This process cannot stop short of the primordial cell, which again will probably turn out to be but a brief resting-place. We therefore prove each one of us to _be actually_ the primordial cell which never died nor dies, but has differentiated itself into the life of the world, all living beings whatever, being one with it, and members one of another.

To look at the matter for a moment in another light, it will be admitted that if the primordial cell had been killed before leaving issue, all its possible descendants would have been killed at one and the same time. It is hard to see how this single fact does not establish at the point, as it were, of a logical bayonet, an identity between any creature and all others that are descended from it.

The fencing (for it does not deserve the name of serious disputation) with which Bishop Butler meets his opponents is rendered possible by the laxness with which the words "identical" and "identity" are ordinarily used. Bishop Butler would not seriously deny that personality undergoes great changes between infancy and old age, and hence that it must undergo some change from moment to moment. So universally is this recognised, that it is common to hear it said of such and such a man that he is not at all the person he was, or of such and such another that he is twice the man he used to be--expressions than which none nearer the truth can well be found. On the other hand, those whom Bishop Butler is intending to confute would be the first to admit that, though there are many changes between infancy and old age, yet they come about in any one individual under such circumstances as we are all agreed in considering as the factors of personal identity rather than as hindrances thereto--that is to say that there has been no entire and permanent death on the part of the individual between any two phases of his existence, and that any one phase has had a lasting though perhaps imperceptible effect upon all succeeding ones. So that no one ever seriously argued in the manner supposed by Bishop Butler, unless with modifications and saving clauses, to which it does not suit his purpose to call attention.

No doubt it would be more strictly accurate to say "you are the now phase of the person I met last night," or "you are the being which has been evolved from the being I met last night," than "you are the person I met last night." But life is too short for the periphrases which would crowd upon us from every quarter, if we did not set our face against all that is under the surface of things, unless, that is to say, the going beneath the surface is, for some special chance of profit, excusable or capable of extenuation.
