Life and Habit

by Samuel Butler

Why should the embryo of any animal go through so many stages—embryological allusions to forefathers of a widely different type? And why, again, should the germs of the same kind of creature always go through the same stages? If the germ of any animal now living is, in its simplest state, but part of the personal identity of one of the original germs of all life whatsoever, and hence, if any now living organism must be considered without quibble as being itself millions of years old, and as imbued with an intense though unconscious memory of all that it has done sufficiently often to have made a permanent impression; if this be so, we can answer the above questions perfectly well. The creature goes through so many intermediate stages between its earliest state as life at all, and its latest development, for the simplest of all reasons, namely, because this is the road by which it has always hitherto travelled to its present differentiation; this is the road it knows, and into every turn and up or down of which, it has been guided by the force of circumstances and the balance of considerations. These, acting in such a manner for such and such a time, caused it to travel in such and such fashion, which fashion having been once sufficiently established, becomes a matter of trick or routine to which the creature is still a slave, and in which it confirms itself by repetition in each succeeding generation.

Thus I suppose, as almost every one else, so far as I can gather, supposes, that we are descended from ancestors of widely different characters to our own. If we could see some of our forefathers a million years back, we should find them unlike anything we could call man; if we were to go back fifty million years, we should find them, it may be, fishes pure and simple, breathing through gills, and unable to exist for many minutes in air.

It is admitted on all hands that there is more or less analogy between the embryological development of the individual, and the various phases or conditions of life through which his forefathers have passed. I suppose, then, that the fish of fifty million years back and the man of to-day are one single living being, in the same sense, or very nearly so, as the octogenarian is one single living being with the infant from which he has grown; and that the fish has lived himself into manhood, not as we live out our little life, living, and living, and living till we die, but living by pulsations, so to speak; living so far, and after a certain time going into a new body, and throwing off the old; making his body much as we make anything that we want, and have often made already, that is to say, as nearly as may be in the same way as he made it last time; also that he is as unable as we ourselves are, to make what he wants without going through the usual processes with which he is familiar, even though there may be other better ways of doing the same thing, which might not be far to seek, if the creature thought them better, and had not got so accustomed to such and such a method, that he would only be baffled and put out by any attempt to teach him otherwise.

And this oneness of personality between ourselves and our supposed fishlike ancestors of many millions of years ago, must hold also between each individual one of us and the single pair of fishes from which we are each (on the present momentary hypothesis) descended; and it must also hold between such pair of fishes and all their descendants besides man, it may be some of them birds, and others fishes; all these descendants, whether human or otherwise, being but the way in which the creature (which was a pair of fishes when we first took it in hand though it was a hundred thousand other things as well, and had been all manner of other things before any part of it became fishlike) continues to exist—its manner, in fact, of growing. As the manner in which the human body grows is by the continued birth and death, in our single lifetime, of many generations of cells which we know nothing about, but say that we have had only one hand or foot all our lives, when we have really had many, one after another; so this huge compound creature, LIFE, probably thinks itself but one single animal whose component cells, as it may imagine, grow, and it may be waste and repair, but do not die.

It may be that the cells of which we are built up, and which we have already seen must be considered as separate persons, each one of them with a life and memory of its own—it may be that these cells reckon time in a manner inconceivable by us, so that no word can convey any idea of it whatever. What may to them appear a long and painful process may to us be so instantaneous as to escape us altogether, we wanting some microscope to show us the details of time. If, in like manner, we were to allow our imagination to conceive the existence of a being as much in need of a microscope for our time and affairs as we for those of our own component cells, the years would be to such a being but as the winkings or the twinklings of an eye. Would he think, then, that all the ants and flies of one wink were different from those of the next? or would he not rather believe that they were always the same flies, and, again, always the same men and women, if he could see them at all, and if the whole human race did not appear to him as a sort of spreading and lichen-like growth over the earth, not differentiated at all into individuals? With the help of a microscope and the intelligent exercise of his reason, he would in time conceive the truth. He would put Covent Garden Market on the field of his microscope, and would perhaps write a great deal of nonsense about the unerring “instinct” which taught each costermonger to recognise his own basket or his own donkey-cart; and this, mutatis mutandis, is what we are getting to do as regards our own bodies. What I wish is, to make the same sort of step in an upward direction which has already been taken in a downward one, and to show reason for thinking that we are only component atoms of a single compound creature, LIFE, which has probably a distinct conception of its own personality though none whatever of ours, more than we of our own units. I wish also to show reason for thinking that this creature, LIFE, has only come to be what it is, by the same sort of process as that by which any human art or manufacture is developed, i.e., through constantly doing the same thing over and over again, beginning from something which is barely recognisable as faith, or as the desire to know, or do, or live at all, and as to the origin of which we are in utter darkness,—and growing till it is first conscious of effort, then conscious of power, then powerful with but little consciousness, and finally, so powerful and so charged with memory as to be absolutely without all self-consciousness whatever, except as regards its latest phases in each of its many differentiations, or when placed in such new circumstances as compel it to choose between death and a reconsideration of its position.

No conjecture can be hazarded as to how the smallest particle of matter became so imbued with faith that it must be considered as the beginning of LIFE, or as to what such faith is, except that it is the very essence of all things, and that it has no foundation.

In this way, then, I conceive we can fairly transfer the experience of the race to the individual, without any other meaning to our words than what they would naturally suggest; that is to say, that there is in every impregnate ovum a bonâ fide memory, which carries it back not only to the time when it was last an impregnate ovum, but to that earlier date when it was the very beginning of life at all, which same creature it still is, whether as man or ovum, and hence imbued, so far as time and circumstance allow, with all its memories. Surely this is no strained hypothesis; for the mere fact that the germ, from the earliest moment that we are able to detect it, appears to be so perfectly familiar with its business, acts with so little hesitation and so little introspection or reference to principles, this alone should incline us to suspect that it must be armed with that which, so far as we observe in daily life, can alone ensure such a result—to wit, long practice, and the memory of many similar performances.

The difficulty is, that we are conscious of no such memory in our own persons, and beyond the one great proof of memory given by the actual repetition of the performance—and of some of the latest deviations from the ordinary performance (and this proof ought in itself, one would have thought, to outweigh any save the directest evidence to the contrary) we can detect no symptom of any such mental operation as recollection on the part of the embryo. On the other hand, we have seen that we know most intensely those things that we are least conscious of knowing; we will most intensely what we are least conscious of willing; we feel continually without knowing that we feel, and our attention is hourly arrested without our attention being arrested by the arresting of our attention. Memory is no less capable of unconscious exercise, and on becoming intense through frequent repetition, vanishes no less completely as a conscious action of the mind than knowledge and volition. We must all be aware of instances in which it is plain we must have remembered, without being in the smallest degree conscious of remembering. Is it then absurd to suppose that our past existences have been repeated on such a vast number of occasions that the germ, linked on to all preceding germs, and, by once having become part of their identity, imbued with all their memories, remembers too intensely to be conscious of remembering, and works on with the same kind of unconsciousness with which we play, or walk, or read, until something unfamiliar happens to us? and is it not singularly in accordance with this view that consciousness should begin with that part of the creature’s performance with which it is least familiar, as having repeated it least often—that is to say, in our own case, with the commencement of our human life—at birth, or thereabouts?

It is certainly noteworthy that the embryo is never at a loss, unless something happens to it which has not usually happened to its forefathers, and which in the nature of things it cannot remember.

When events are happening to it which have ordinarily happened to its forefathers, and which it would therefore remember, if it was possessed of the kind of memory which we are here attributing to it, it acts precisely as it would act if it were possessed of such memory.
