ill. That we are most unconscious of, and have least control over, our digestion, which we have in common even with our invertebrate ancestry, and which is a habit 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 illustration 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—which, however, in practice is just what you must have.
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, and 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 passionate 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 passionate argument once what shape a man’s teeth should be, nor can the colour of his hair be considered as even 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 unruly hordes within him at this moment and overmastering him. “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 multitude. “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 hither 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 fashion. Sanction sanctifieth and fashion fashioneth. And so with death—the most inexorable of all conventions.
However this may be, we may assume 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, 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.
