Part 2 (2/2)
Can we also show that there are no acquired actions which we can perform in this automatic manner, which were not at one time difficult, requiring attention, and liable to repeated failure, our volition failing to command obedience from the members which should carry its purposes into execution?
If so, a.n.a.logy will point in the direction of thinking that other acts which we do even more unconsciously may only escape our power of self-examination and control because they are even more familiar-- because we have done them oftener; and we may imagine that if there were a microscope which could show us the minutest atoms of consciousness and volition, we should find that even the apparently most automatic actions were yet done in due course, upon a balance of considerations, and under the deliberate exercise of the will.
We should also incline to think that even such an action as the oxygenisation of its blood by an infant of ten minutes' old, can only be done so well and so unconsciously, after repeated failures on the part of the infant itself.
True, as has been already implied, we do not immediately see when the baby could have made the necessary mistakes and acquired that infinite practice without which it could never go through such complex processes satisfactorily; we have therefore invented the words ”hereditary instinct,” and consider them as accounting for the phenomenon; but a very little reflection will show that though these words may be a very good way of stating the difficulty, they do little or nothing towards removing it.
Why should hereditary instinct enable a creature to dispense with the experience which we see to be necessary in all other cases before difficult operations can be performed successfully?
What is this talk that is made about the experience OF THE RACE, as though the experience of one man could profit another who knows nothing about him? If a man eats his dinner, it nourishes HIM and not his neighbour; if he learns a different art, it is HE that can do it and not his neighbour. Yet, practically, we see that the vicarious experience, which seems so contrary to our common observation, does nevertheless appear to hold good in the case of creatures and their descendants. Is there, then, any way of bringing these apparently conflicting phenomena under the operation of one law? Is there any way of showing that this experience of the race, of which so much is said without the least attempt to show in what way it may or does become the experience of the individual, is in sober seriousness the experience of one single being only, repeating in a great many different ways certain performances with which he has become exceedingly familiar?
It would seem that we must either suppose the conditions of experience to differ during the earlier stages of life from those which we observe them to become during the heyday of any existence-- and this would appear very gratuitous, tolerable only as a suggestion because the beginnings of life are so obscure, that in such twilight we may do pretty much whatever we please without danger of confutation--or that we must suppose the continuity of life and sameness between living beings, whether plants or animals, and their descendants, to be far closer than we have hitherto believed; so that the experience of one person is not enjoyed by his successor, so much as that the successor is bona fide but a part of the life of his progenitor, imbued with all his memories, profiting by all his experiences--which are, in fact, his own--and only unconscious of the extent of his own memories and experiences owing to their vastness and already infinite repet.i.tions.
Certainly it presents itself to us at once as a singular coincidence -
I. That we are MOST CONSCIOUS OF, AND HAVE MOST CONTROL OVER, such habits as speech, the upright position, the arts and sciences, which are acquisitions peculiar to the human race, always acquired after birth, and not common to ourselves and any ancestor who had not become entirely human.
II. That we are LESS CONSCIOUS OF, AND HAVE LESS CONTROL OVER, eating and drinking, swallowing, breathing, seeing and hearing, which were acquisitions of our prehuman ancestry, and for which we had provided ourselves with all the necessary apparatus before we saw light, but which are still, geologically speaking, recent, or comparatively recent.
III. That we are MOST UNCONSCIOUS OF, AND HAVE LEAST CONTROL OVER, our digestion and circulation, which belonged even to our invertebrate ancestry, and which are habits, geologically speaking, of extreme antiquity.
There is something too like method in this for it to be taken as the result of mere chance--chance again being but another ill.u.s.tration of Nature's love of a contradiction in terms; for everything is chance, and nothing is chance. And you may take it that all is chance or nothing chance, according as you please, but you must not have half chance and half not chance.
Does it not seem as though the older and more confirmed the habit, the more unquestioning the act of volition, till, in the case of the oldest habits, the practice of succeeding existences has so formulated the procedure, that, on being once committed to such and such a line beyond a certain point, the subsequent course is so clear as to be open to no further doubt, to admit of no alternative, till the very power of questioning is gone, and even the consciousness of volition? And this too upon matters which, in earlier stages of a man's existence, admitted of pa.s.sionate argument and anxious deliberation whether to resolve them thus or thus, with heroic hazard and experiment, which on the losing side proved to be vice, and on the winning virtue. For there was pa.s.sionate argument once what shape a man's teeth should be, nor can the colour of his hair be considered as ever yet settled, or likely to be settled for a very long time.
It is one against legion when a creature tries to differ from his own past selves. He must yield or die if he wants to differ widely, so as to lack natural instincts, such as hunger or thirst, or not to gratify them. It is more righteous in a man that he should ”eat strange food,” and that his cheek should ”so much as lank not,” than that he should starve if the strange food be at his command. His past selves are living in him at this moment with the acc.u.mulated life of centuries. ”Do this, this, this, which we too have done, and found our profit in it,” cry the souls of his forefathers within him.
Faint are the far ones, coming and going as the sound of bells wafted on to a high mountain; loud and clear are the near ones, urgent as an alarm of fire. ”Withhold,” cry some. ”Go on boldly,” cry others.
”Me, me, me, revert hitherward, my descendant,” shouts one as it were from some high vantage-ground over the heads of the clamorous mult.i.tude. ”Nay, but me, me, me,” echoes another; and our former selves fight within us and wrangle for our possession. Have we not here what is commonly called an INTERNAL TUMULT, when dead pleasures and pains tug within us. .h.i.ther and thither? Then may the battle be decided by what people are pleased to call our own experience. Our own indeed! What is our own save by mere courtesy of speech? A matter of fas.h.i.+on. Sanction sanctifieth and fas.h.i.+on fas.h.i.+oneth. And so with death--the most inexorable of all conventions.
However this may be, we may a.s.sume it as an axiom with regard to actions acquired after birth, that we never do them automatically save as the result of long practice, and after having thus acquired perfect mastery over the action in question.
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, as it were mechanically 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 a knowledge of the facts concerning optics and acoustics, compared with which the 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 a.s.sertion 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 pa.s.ses 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 a.s.sertion would find some other instances of intricate processes gone through by people who know nothing about them, and 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 we have 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 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 breath, the punishment is corporal, breathing being a matter of fas.h.i.+on, 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 fas.h.i.+on 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 acc.u.mulated, till it forms vast continents many thousands of feet above the level of the sea, all of solid ice. The weight of this ma.s.s 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 time 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 sh.e.l.lfish 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 apprentices.h.i.+p 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 l.u.s.t 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.
