”The vapour-engine must be fed with food and consume it by fire even as man consumes it; it supports its combustion by air as man supports it; it has a pulse and circulation as man has. It may be granted that man's body is as yet the more versatile of the two, but then man's body is an older thing; give the vapour-engine but half the time that man has had, give it also a continuance of our present infatuation, and what may it not ere long attain to?
”There are certain functions indeed of the vapour-engine which will probably remain unchanged for myriads of years--which in fact will perhaps survive when the use of vapour has been superseded: the piston and cylinder, the beam, the fly-wheel, and other parts of the machine will probably be permanent, just as we see that man and many of the lower animals share like modes of eating, drinking, and sleeping; thus they have hearts which beat as ours, veins and arteries, eyes, ears, and noses; they sigh even in their sleep, and weep and yawn; they are affected by their children; they feel pleasure and pain, hope, fear, anger, shame; they have memory and prescience; they know that if certain things happen to them they will die, and they fear death as much as we do; they communicate their thoughts to one another, and some of them deliberately act in concert. The comparison of similarities is endless: I only make it because some may say that since the vapour-engine is not likely to be improved in the main particulars, it is unlikely to be henceforward extensively modified at all. This is too good to be true: it will be modified and suited for an infinite variety of purposes, as much as man has been modified so as to exceed the brutes in skill.
”In the meantime the stoker is almost as much a cook for his engine as our own cooks for ourselves. Consider also the colliers and pitmen and coal merchants and coal trains, and the men who drive them, and the s.h.i.+ps that carry coals--what an army of servants do the machines thus employ!
Are there not probably more men engaged in tending machinery than in tending men? Do not machines eat as it were by mannery? Are we not ourselves creating our successors in the supremacy of the earth? daily adding to the beauty and delicacy of their organisation, daily giving them greater skill and supplying more and more of that self-regulating self-acting power which will be better than any intellect?
”What a new thing it is for a machine to feed at all! The plough, the spade, and the cart must eat through man's stomach; the fuel that sets them going must burn in the furnace of a man or of horses. Man must consume bread and meat or he cannot dig; the bread and meat are the fuel which drive the spade. If a plough be drawn by horses, the power is supplied by gra.s.s or beans or oats, which being burnt in the belly of the cattle give the power of working: without this fuel the work would cease, as an engine would stop if its furnaces were to go out.
”A man of science has demonstrated 'that no animal has the power of originating mechanical energy, but that all the work done in its life by any animal, and all the heat that has been emitted from it, and the heat which would be obtained by burning the combustible matter which has been lost from its body during life, and by burning its body after death, make up altogether an exact equivalent to the heat which would be obtained by burning as much food as it has used during its life, and an amount of fuel which would generate as much heat as its body if burned immediately after death.' I do not know how he has found this out, but he is a man of science--how then can it be objected against the future vitality of the machines that they are, in their present infancy, at the beck and call of beings who are themselves incapable of originating mechanical energy?
”The main point, however, to be observed as affording cause for alarm is, that whereas animals were formerly the only stomachs of the machines, there are now many which have stomachs of their own, and consume their food themselves. This is a great step towards their becoming, if not animate, yet something so near akin to it, as not to differ more widely from our own life than animals do from vegetables. And though man should remain, in some respects, the higher creature, is not this in accordance with the practice of nature, which allows superiority in some things to animals which have, on the whole, been long surpa.s.sed? Has she not allowed the ant and the bee to retain superiority over man in the organisation of their communities and social arrangements, the bird in traversing the air, the fish in swimming, the horse in strength and fleetness, and the dog in self-sacrifice?
”It is said by some with whom I have conversed upon this subject, that the machines can never be developed into animate or _quasi_-animate existences, inasmuch as they have no reproductive system, nor seem ever likely to possess one. If this be taken to mean that they cannot marry, and that we are never likely to see a fertile union between two vapour- engines with the young ones playing about the door of the shed, however greatly we might desire to do so, I will readily grant it. But the objection is not a very profound one. No one expects that all the features of the now existing organisations will be absolutely repeated in an entirely new cla.s.s of life. The reproductive system of animals differs widely from that of plants, but both are reproductive systems.
Has nature exhausted her phases of this power?
”Surely if a machine is able to reproduce another machine systematically, we may say that it has a reproductive system. What is a reproductive system, if it be not a system for reproduction? And how few of the machines are there which have not been produced systematically by other machines? But it is man that makes them do so. Yes; but is it not insects that make many of the plants reproductive, and would not whole families of plants die out if their fertilisation was not effected by a cla.s.s of agents utterly foreign to themselves? Does any one say that the red clover has no reproductive system because the humble bee (and the humble bee only) must aid and abet it before it can reproduce? No one.
The humble bee is a part of the reproductive system of the clover. Each one of ourselves has sprung from minute animalcules whose ent.i.ty was entirely distinct from our own, and which acted after their kind with no thought or heed of what we might think about it. These little creatures are part of our own reproductive system; then why not we part of that of the machines?
”But the machines which reproduce machinery do not reproduce machines after their own kind. A thimble may be made by machinery, but it was not made by, neither will it ever make, a thimble. Here, again, if we turn to nature we shall find abundance of a.n.a.logies which will teach us that a reproductive system may be in full force without the thing produced being of the same kind as that which produced it. Very few creatures reproduce after their own kind; they reproduce something which has the potentiality of becoming that which their parents were. Thus the b.u.t.terfly lays an egg, which egg can become a caterpillar, which caterpillar can become a chrysalis, which chrysalis can become a b.u.t.terfly; and though I freely grant that the machines cannot be said to have more than the germ of a true reproductive system at present, have we not just seen that they have only recently obtained the germs of a mouth and stomach? And may not some stride be made in the direction of true reproduction which shall be as great as that which has been recently taken in the direction of true feeding?
”It is possible that the system when developed may be in many cases a vicarious thing. Certain cla.s.ses of machines may be alone fertile, while the rest discharge other functions in the mechanical system, just as the great majority of ants and bees have nothing to do with the continuation of their species, but get food and store it, without thought of breeding.
One cannot expect the parallel to be complete or nearly so; certainly not now, and probably never; but is there not enough a.n.a.logy existing at the present moment, to make us feel seriously uneasy about the future, and to render it our duty to check the evil while we can still do so? Machines can within certain limits beget machines of any cla.s.s, no matter how different to themselves. Every cla.s.s of machines will probably have its special mechanical breeders, and all the higher ones will owe their existence to a large number of parents and not to two only.
”We are misled by considering any complicated machine as a single thing; in truth it is a city or society, each member of which was bred truly after its kind. We see a machine as a whole, we call it by a name and individualise it; we look at our own limbs, and know that the combination forms an individual which springs from a single centre of reproductive action; we therefore a.s.sume that there can be no reproductive action which does not arise from a single centre; but this a.s.sumption is unscientific, and the bare fact that no vapour-engine was ever made entirely by another, or two others, of its own kind, is not sufficient to warrant us in saying that vapour-engines have no reproductive system. The truth is that each part of every vapour-engine is bred by its own special breeders, whose function it is to breed that part, and that only, while the combination of the parts into a whole forms another department of the mechanical reproductive system, which is at present exceedingly complex and difficult to see in its entirety.
”Complex now, but how much simpler and more intelligibly organised may it not become in another hundred thousand years? or in twenty thousand? For man at present believes that his interest lies in that direction; he spends an incalculable amount of labour and time and thought in making machines breed always better and better; he has already succeeded in effecting much that at one time appeared impossible, and there seem no limits to the results of acc.u.mulated improvements if they are allowed to descend with modification from generation to generation. It must always be remembered that man's body is what it is through having been moulded into its present shape by the chances and changes of many millions of years, but that his organisation never advanced with anything like the rapidity with which that of the machines is advancing. This is the most alarming feature in the case, and I must be pardoned for insisting on it so frequently.”
CHAPTER XXV: THE MACHINES--concluded
Here followed a very long and untranslatable digression about the different races and families of the then existing machines. The writer attempted to support his theory by pointing out the similarities existing between many machines of a widely different character, which served to show descent from a common ancestor. He divided machines into their genera, subgenera, species, varieties, subvarieties, and so forth. He proved the existence of connecting links between machines that seemed to have very little in common, and showed that many more such links had existed, but had now perished. He pointed out tendencies to reversion, and the presence of rudimentary organs which existed in many machines feebly developed and perfectly useless, yet serving to mark descent from an ancestor to whom the function was actually useful.
I left the translation of this part of the treatise, which, by the way, was far longer than all that I have given here, for a later opportunity.
Unfortunately, I left Erewhon before I could return to the subject; and though I saved my translation and other papers at the hazard of my life, I was a obliged to sacrifice the original work. It went to my heart to do so; but I thus gained ten minutes of invaluable time, without which both Arowhena and myself must have certainly perished.
I remember one incident which bears upon this part of the treatise. The gentleman who gave it to me had asked to see my tobacco-pipe; he examined it carefully, and when he came to the little protuberance at the bottom of the bowl he seemed much delighted, and exclaimed that it must be rudimentary. I asked him what he meant.
”Sir,” he answered, ”this organ is identical with the rim at the bottom of a cup; it is but another form of the same function. Its purpose must have been to keep the heat of the pipe from marking the table upon which it rested. You would find, if you were to look up the history of tobacco- pipes, that in early specimens this protuberance was of a different shape to what it is now. It will have been broad at the bottom, and flat, so that while the pipe was being smoked the bowl might rest upon the table without marking it. Use and disuse must have come into play and reduced the function to its present rudimentary condition. I should not be surprised, sir,” he continued, ”if, in the course of time, it were to become modified still farther, and to a.s.sume the form of an ornamental leaf or scroll, or even a b.u.t.terfly, while, in some cases, it will become extinct.”
On my return to England, I looked up the point, and found that my friend was right.
Returning, however, to the treatise, my translation recommences as follows:-
”May we not fancy that if, in the remotest geological period, some early form of vegetable life had been endowed with the power of reflecting upon the dawning life of animals which was coming into existence alongside of its own, it would have thought itself exceedingly acute if it had surmised that animals would one day become real vegetables? Yet would this be more mistaken than it would be on our part to imagine that because the life of machines is a very different one to our own, there is therefore no higher possible development of life than ours; or that because mechanical life is a very different thing from ours, therefore that it is not life at all?
”But I have heard it said, 'granted that this is so, and that the vapour- engine has a strength of its own, surely no one will say that it has a will of its own?' Alas! if we look more closely, we shall find that this does not make against the supposition that the vapour-engine is one of the germs of a new phase of life. What is there in this whole world, or in the worlds beyond it, which has a will of its own? The Unknown and Unknowable only!
”A man is the resultant and exponent of all the forces that have been brought to bear upon him, whether before his birth or afterwards. His action at any moment depends solely upon his const.i.tution, and on the intensity and direction of the various agencies to which he is, and has been, subjected. Some of these will counteract each other; but as he is by nature, and as he has been acted on, and is now acted on from without, so will he do, as certainly and regularly as though he were a machine.
