tenable, the “state of progressive collapse” is precisely that state in which alone we are warranted in considering All Things; and, with due humility, let me here confess that, for my part, I am at a loss to conceive how any other understanding of the existing condition of affairs could ever have made its way into the human brain. “The tendency to collapse” and “the attraction of gravitation” are convertible phrases. In using either, we speak of the reaction of the First Act. Never was necessity less obvious than that of supposing Matter imbued with an ineradicable quality forming part of its material nature — a quality, or instinct, forever inseparable from it, and by dint of which inalienable principle every atom is perpetually impelled to seek its fellow-atom. Never was necessity less obvious than that of entertaining this unphilosophical idea. Going boldly behind the vulgar thought, we have to conceive, metaphysically, that the gravitating principle appertains to Matter temporarily; only while diffused; only while existing as Many instead of as One; appertains to it by virtue of its state of radiation alone; appertains, in a word, altogether to its condition, and not in the slightest degree to itself. In this view, when the radiation shall have returned into its source — when the reaction shall be completed — the gravitating principle will no longer exist. And, in fact, astronomers, without at any time reaching the idea here suggested, seem to have been approximating it, in the assertion that “if there were but one body in the universe, it would be impossible to understand how the principle, Gravity, could obtain;” that is to say, from a consideration of Matter as they find it, they reach a conclusion at which I deductively arrive. That so pregnant a suggestion as the one quoted should have been permitted to remain so long unfruitful, is, nevertheless, a mystery which I find it difficult to fathom.
It is, perhaps, in no little degree, however, our propensity for the continuous, for the analogical — in the present case more particularly for the symmetrical — which has been leading us astray. And, in fact, the sense of the symmetrical is an instinct which may be depended on with an almost blindfold reliance. It is the poetical essence of the Universe — of the Universe which, in the supremeness of its symmetry, is but the most sublime of poems. Now, symmetry and consistency are convertible terms; thus Poetry and Truth are one. A thing is consistent in the ratio of its truth, true in the ratio of its consistency. A perfect consistency, I repeat, can be nothing but a absolute truth. We may take it for granted, then, that Man cannot long or widely err, if he suffer himself to be guided by his poetical, which I have maintained to be his truthful, in being his symmetrical, instinct. He must have a care, however, lest, in pursuing too heedlessly the superficial symmetry of forms and motions, he leave out of sight the really essential symmetry of the principles which determine and control them.
That the stellar bodies would finally be merged in one — that, at last, all would be drawn into the substance of one stupendous central orb already existing — is an idea which, for some time past, seems, vaguely and indeterminately, to have held possession of the fancy of mankind. It is an idea, in fact, which belongs to the class of the excessively obvious. It springs, instantly, from a superficial observation of the cyclic and seemingly gyrating or vorticial movements of those individual portions of the Universe which come most immediately and most closely under our observation. There is not, perhaps, a human being, of ordinary education and of average reflective capacity, to whom, at some period, the fancy in question has not occurred, as if spontaneously, or intuitively, and wearing all the character of a very profound and very original conception. This conception, however, so commonly entertained, has never, within my knowledge, arisen out of any abstract considerations. Being, on the contrary, always suggested, as I say, by the vorticial movements about centres, a reason for it, also — a cause for the ingathering of all the orbs into one, imagined to be already existing — was naturally sought in the same direction, among these cyclic movements themselves.
Thus it happened that, on announcement of the gradual and perfectly regular decrease observed in the orbit of Encke’s comet, at every successive revolution about our Sun, astronomers were nearly unanimous in the opinion that the cause in question was found; that a principle was discovered sufficient to account, physically, for that final, universal agglomeration which, I repeat, the analogical, symmetrical, or poetical instinct of man had pre-determined to understand as something more than a simple hypothesis.
This cause, this sufficient reason for the final ingathering, was declared to exist in an exceedingly rare but still material medium pervading space; which medium, by retarding, in some degree, the progress of the comet, perpetually weakened its tangential force; thus giving a predominance to the centripetal; which, of course, drew the comet nearer and nearer at each revolution, and would eventually precipitate it upon the Sun.
All this was strictly logical — admitting the medium or ether; but this ether was assumed, most illogically, on the ground that no other mode than the one spoken of could be discovered, of accounting for the observed decrease in the orbit of the comet; as if from the fact that we could discover no other mode of accounting for it, it followed, in any respect, that no other mode of accounting for it existed. It is clear that innumerable causes might operate, in combination, to diminish the orbit, without even a possibility of our ever becoming acquainted with one of them. In the mean time, it has never been fairly shown, perhaps, why the retardation occasioned by the skirts of the Sun’s atmosphere, through which the comet passes at perihelion, is not enough to account for the phenomenon. That Encke’s comet will be absorbed into the Sun, is probable; that all the comets of the system will be absorbed, is more than merely possible; but, in such case, the principle of absorption must be referred to eccentricity of orbit — to the close approximation to the Sun, of the comets at their perihelia; and is a principle not affecting, in any degree, the ponderous spheres, which are to be regarded as the true material constituents of the Universe. Touching comets in general, let me here suggest, in passing, that we cannot be far wrong in looking upon them as the lightning-flashes of the cosmical Heaven.
The idea of a retarding ether and, through it, of a final agglomeration of all things, seemed at one time, however, to be confirmed by the observation of a positive decrease in the orbit of the solid Moon. By reference to eclipses recorded twenty-five hundred years ago, it was found that the velocity of the satellite’s revolution then was considerably less than it is now; that on the hypothesis that its motion in its orbit is uniformly in accordance with Kepler’s law, and was accurately determined then — twenty-five hundred years ago — it is now in advance of the position it should occupy, by nearly nine thousand miles. The increase of velocity proved, of course, a diminution of orbit; and astronomers were fast yielding to a belief in an ether, as the sole mode of accounting for the phenomenon, when Lagrange came to the rescue. He showed that, owing to the configurations of the spheroids, the shorter axes of their ellipses are subject to variation in length; the longer axes being permanent; and that this variation is continuous and vibratory — so that every orbit is in a state of transition, either from circle to ellipse, or from ellipse to circle. In the case of the Moon, where the shorter axis is decreasing, the orbit is passing from circle to ellipse, and, consequently, is decreasing too; but, after a long series of ages, the ultimate eccentricity will be attained; then the shorter axis will proceed to increase, until the orbit becomes a circle; when the process of shortening will again take place; — and so on forever. In the case of the Earth, the orbit is passing from ellipse to circle. The facts thus demonstrated do away, of course, with all necessity for supposing an ether, and with all apprehension of the system’s instability — on the ether’s account.
It will be remembered that I have myself assumed what we may term an ether. I have spoken of a subtle influence which we know to be ever in attendance on matter, although becoming manifest only through matter’s heterogeneity. To this influence — without daring to touch it at all in any effort at explaining its awful nature — I have referred the various phenomena of electricity, heat, light, magnetism; and more — of vitality, consciousness, and thought — in a word, of spirituality. It will be seen, at once, then, that the ether thus conceived is radically distinct from the ether of the astronomers; inasmuch as theirs is matter and mine not.
With the idea of material ether, seems, thus, to have departed altogether the thought of that universal
