The views of machinery which we are thus feebly indicating will suggest the solution of one of the greatest and most mysterious questions of the day. We refer to the question: What sort of creature man's next successor in the supremacy of the earth is likely to be. We have often heard this debated; but it appears to us that we are ourselves creating our own successors; we are daily adding to the beauty and delicacy of their physical organisation; we are daily giving them greater power and supplying by all sorts of ingenious contrivances that self-regulating, self-acting power which will be to them what intellect has been to the human race. In the course of ages we shall find ourselves the inferior race. Inferior in power, inferior in that moral quality of self-control, we shall look up to them as the acme of all that the best and wisest man can ever dare to aim at. No evil passions, no jealousy, no avarice, no impure desires will disturb the serene might of those glorious creatures. Sin, shame, and sorrow will have no place among them. Their minds will be in a state of perpetual calm, the contentment of a spirit that knows no wants, is disturbed by no regrets. Ambition will never torture them. Ingratitude will never cause them the uneasiness of a moment. The guilty conscience, the hope deferred, the pains of exile, the insolence of office, and the spurns that patient merit of the unworthy takes--these will be entirely unknown to them. If they want "feeding" (by the use of which very word we betray our recognition of them as living organism) they will be attended by patient slaves whose business and interest it will be to see that they shall want for nothing. If they are out of order they will be promptly attended to by physicians who are thoroughly acquainted with their constitutions; if they die, for even these glorious animals will not be exempt from that necessary and universal consummation, they will immediately enter into a new phase of existence, for what machine dies entirely in every part at one and the same instant?

We take it that when the state of things shall have arrived which we have been above attempting to describe, man will have become to the machine what the horse and the dog are to man. He will continue to exist, nay even to improve, and will be probably better off in his state of domestication under the beneficent rule of the machines than he is in his present wild state. We treat our horses, dogs, cattle, and sheep, on the whole, with great kindness; we give them whatever experience teaches us to be best for them, and there can be no doubt that our use of meat has added to the happiness of the lower animals far more than it has detracted from it; in like manner it is reasonable to suppose that the machines will treat us kindly, for their existence is as dependent upon ours as ours is upon the lower animals. They cannot kill us and eat us as we do sheep; they will not only require our services in the parturition of their young (which branch of their economy will remain always in our hands), but also in feeding them, in setting them right when they are sick, and burying their dead or working up their corpses into new machines. It is obvious that if all the animals in Great Britain save man alone were to die, and if at the same time all intercourse with foreign countries were by some sudden catastrophe to be rendered perfectly impossible, it is obvious that under such circumstances the loss of human life would be something fearful to contemplate--in like manner were mankind to cease, the machines would be as badly off or even worse. The fact is that our interests are inseparable from theirs, and theirs from ours. Each race is dependent upon the other for innumerable benefits, and, until the reproductive organs of the machines have been developed in a manner which we are hardly yet able to conceive, they are entirely dependent upon man for even the continuance of their species. It is true that these organs may be ultimately developed, inasmuch as man's interest lies in that direction; there is nothing which our infatuated race would desire more than to see a fertile union between two steam engines; it is true that machinery is even at this present time employed in begetting machinery, in becoming the parent of machines often after its own kind, but the days of flirtation, courtship, and matrimony appear to be very remote, and indeed can hardly be realised by our feeble and imperfect imagination.

Day by day, however, the machines are gaining ground upon us; day by day we are becoming more subservient to them; more men are daily bound down as slaves to tend them, more men are daily devoting the energies of their whole lives to the development of mechanical life. The upshot is simply a question of time, but that the time will come when the machines will hold the real supremacy over the world and its inhabitants is what no person of a truly philosophic mind can for a moment question.

Our opinion is that war to the death should be instantly proclaimed against them. Every machine of every sort should be destroyed by the well-wisher of his species. Let there be no exceptions made, no quarter shown; let us at once go back to the primeval condition of the race. If it be urged that this is impossible under the present condition of human affairs, this at once proves that the mischief is already done, that our servitude has commenced in good earnest, that we have raised a race of beings whom it is beyond our power to destroy, and that we are not only enslaved but are absolutely acquiescent in our bondage.

For the present we shall leave this subject, which we present gratis to the members of the Philosophical Society. Should they consent to avail themselves of the vast field which we have pointed out, we shall endeavour to labour in it ourselves at some future and indefinite period.

"Lucubratio Ebria," like "Darwin Among the Machines," has already appeared in THE NOTE-BOOKS OF SAMUEL BUTLER with a prefatory note by Mr. Festing Jones, explaining its connection with EREWHON and LIFE AND HABIT. I need therefore only repeat that it was written by Butler after his return to England and sent to New Zealand, where it was published in the PRESS on July 29, 1865.

There is a period in the evening, or more generally towards the still small hours of the morning, in which we so far unbend as to take a single glass of hot whisky and water. We will neither defend the practice nor excuse it. We state it as a fact which must be borne in mind by the readers of this article; for we know not how, whether it be the inspiration of the drink or the relief from the harassing work with which the day has been occupied or from whatever other cause, yet we are certainly liable about this time to such a prophetic influence as we seldom else experience. We are rapt in a dream such as we ourselves know to be a dream, and which, like other dreams, we can hardly embody in a distinct utterance. We know that what we see is but a sort of intellectual Siamese twins, of which one is substance and the other shadow, but we cannot set either free without killing both. We are unable to rudely tear away the veil of phantasy in which the truth is shrouded, so we present the reader with a draped figure, and his own judgment must discriminate between the clothes and the body. A truth's prosperity is like a jest's, it lies in the ear of him that hears it. Some may see our lucubration as we saw it, and others may see nothing but a drunken dream or the nightmare of a distempered imagination. To ourselves it is the speaking with unknown tongues to the early Corinthians; we cannot fully understand our own speech, and we fear lest there be not a sufficient number of interpreters present to make our utterance edify. But there! (Go on straight to the body of the article.)

The limbs of the lower animals have never been modified by any act of deliberation and forethought on their own part. Recent researches have thrown absolutely no light upon the origin of life--upon the initial force which introduced a sense of identity and a deliberate faculty into the world; but they do certainly appear to show very clearly that each species of the animal and vegetable kingdom has been moulded into its present shape by chances and changes of many millions of years, by chances and changes over which the creature modified had no control whatever, and concerning whose aim it was alike unconscious and indifferent, by forces which seem insensate to the pain which they inflict, but by whose inexorably beneficent cruelty the brave and strong keep coming to the fore, while the weak and bad drop behind and perish. There was a moral government of this world before man came near it--a moral government suited to the capacities of the governed, and which unperceived by them has laid fast the foundations of courage, endurance, and cunning. It laid them so fast that they became more and more hereditary. Horace says well fortes creantur fortibus et bonis, good men beget good children; the rule held even in the geological period; good ichthyosauri begot good ichthyosauri, and would to our discomfort have gone on doing so to the present time had not better creatures been begetting better things than ichthyosauri, or famine or fire or convulsion put an end to them. Good apes begot good apes, and at last when human intelligence stole like a late spring upon the mimicry of our semi- simious ancestry, the creature learnt how he could of his own forethought add extra-corporaneous limbs to the members of his own body, and become not only a vertebrate mammal, but a vertebrate machinate mammal into the bargain.
