СКАЧАТЬ but the demonstration of the law itself, persist the metaphysicians, had not been strengthened in any degree. "Ocular, physical proof," however, of attraction, here upon Earth, in accordance with the Newtonian theory, was, at length, much to the satisfaction of some intellectual grovellers, afforded. This proof arose collaterally and incidentally (as nearly all important truths have arisen) out of an attempt to ascertain the mean density of the Earth. In the famous Maskelyne, Cavendish and Bailly experiments for this purpose, the attraction of the mass of a mountain was seen, felt, measured, and found to be mathematically consistent with the immortal theory of the British astronomer.

      But in spite of this confirmation of that which needed none –in spite of the so-called corroboration of the "theory" by the so-called "ocular and physical proof" –in spite of the character of this corroboration – the ideas which even really philosophical men cannot help imbibing of gravity –and, especially, the ideas of it which ordinary men get and contentedly maintain, are seen to have been derived, for the most part, from a consideration of the principle as they find it developed –merely in the planet upon which they stand.

      Now, to what does so partial a consideration tend –to what species of error does it give rise? On the Earth we see and feel, only that gravity impels all bodies towards the centre of the Earth. No man in the common walks of life could be made to see or feel anything else – could be made to perceive that anything, anywhere, has a perpetual, gravitating tendency in any other direction than to the centre of the Earth; yet (with an exception hereafter to be specified) it is a fact that every earthly thing (not to speak now of every heavenly thing) has a tendency not only to the Earth's centre but in every conceivable direction besides.

      Now, although the philosophic cannot be said to err with the vulgar in this matter, they nevertheless permit themselves to be influenced, without knowing it, by the sentiment of the vulgar idea. "Although the Pagan fables are not believed," says Bryant, in his very erudite "Mythology," "yet we forget ourselves continually and make inferences from them as from existing realities." I mean to assert that the merely sensitive perception of gravity as we experience it on Earth, beguiles mankind into the fancy of Concentralization or especiality respecting it –has been continually biasing towards this fancy even the mightiest intellects –perpetually, although imperceptibly, leading them away from the real characteristics of the principle; thus preventing them, up to this date, from ever getting a glimpse of that vital truth which lies in a diametrically opposite direction –behind the principle's essential characteristics –those, not of concentralization or especiality –but of universality and diffusion. This "vital truth" is Unity as the source of the phaenomenon.

      Let me now repeat the definition of gravity: –Every atom, of every body, attracts every other atom, both of its own and of every other body, with a force which varies inversely as the squares of the distances of the attracting and attracted atom.

      Here let the reader pause with me, for a moment, in contemplation of the miraculous –of the ineffable –of the altogether unimaginable complexity of relation involved in the fact that each atom attracts every other atom –involved merely in this fact of the attraction, without reference to the law or mode in which the attraction is manifested –involved merely in the fact that each atom attracts every other atom at all, in a wilderness of atoms so numerous that those which go to the composition of a cannon-ball, exceed, probably, in mere point of number, all the stars which go to the constitution of the Universe.

      Had we discovered, simply, that each atom tended to some one favorite point –to some especially attractive atom –we should still have fallen upon a discovery which, in itself, would have sufficed to overwhelm the mind: –but what is it that we are actually called upon to comprehend? That each atom attracts –sympathizes with the most delicate movements of every other atom, and with each and with all at the same time, and forever, and according to a determinate law of which the complexity, even considered by itself solely, is utterly beyond the grasp of the imagination of man. If I propose to ascertain the influence of one mote in a sunbeam upon its neighboring mote, I cannot accomplish my purpose without first counting and weighing all the atoms in the Universe and defining the precise positions of all at one particular moment. If I venture to displace, by even the billionth part of an inch, the microscopical speck of dust which lies now upon the point of my finger, what is the character of that act upon which I have adventured? I have done a deed which shakes the Moon in her path, which causes the Sun to be no longer the Sun, and which alters forever the destiny of the multitudinous myriads of stars that roll and glow in the majestic presence of their Creator.

      These ideas –conceptions such as these –unthought-like thoughts – soul-reveries rather than conclusions or even considerations of the intellect: –ideas, I repeat, such as these, are such as we can alone hope profitably to entertain in any effort at grasping the great principle, Attraction.

      But now, –with such ideas –with such a vision of the marvellous complexity of Attraction fairly in his mind –let any person competent of thought on such topics as these, set himself to the task of imagining a principle for the phaenomena observed –a condition from which they sprang.

      Does not so evident a brotherhood among the atoms point to a common parentage? Does not a sympathy so omniprevalent, so ineradicable, and so thoroughly irrespective, suggest a common paternity as its source? Does not one extreme impel the reason to the other? Does not the infinitude of division refer to the utterness of individuality? Does not the entireness of the complex hint at the perfection of the simple? It is not that the atoms, as we see them, are divided or that they are complex in their relations –but that they are inconceivably divided and unutterably complex: –it is the extremeness of the conditions to which I now allude, rather than to the conditions themselves. In a word, not because the atoms were, at some remote epoch of time, even more than together –is it not because originally, and therefore normally, they were One –that now, in all circumstances –at all points –in all directions –by all modes of approach –in all relations and through all conditions –they struggle back to this absolutely, this irrelatively, this unconditionally one?

      Some person may here demand: –"Why –since it is to the One that the atoms struggle back –do we not find and define Attraction 'a merely general tendency to a centre?' –why, in especial, do not your atoms –the atoms which you describe as having been irradiated from a centre –proceed at once, rectilinearly, back to the central point of their origin?"

      I reply that they do; as will be distinctly shown; but that the cause of their so doing is quite irrespective of the centre as such. They all tend rectilinearly towards a centre, because of the sphereicity with which they have been irradiated into space. Each atom, forming one of a generally uniform globe of atoms, finds more atoms in the direction of the centre, of course, than in any other, and in that direction, therefore, is impelled –but is not thus impelled because the centre is the point of its origin. It is not to any point that the atoms are allied. It is not any locality, either in the concrete or in the abstract, to which I suppose them bound. Nothing like location was conceived as their origin. Their source lies in the principle, Unity. This is their lost parent. This they seek always –immediately –in all directions – wherever it is even partially to be found; thus appeasing, in some measure, the ineradicable tendency, while on the way to its absolute satisfaction in the end. It follows from all this, that any principle which shall be adequate to account for the LA0 or modus operandi, of the attractive force in general, will account for this law in particular: – that is to say, any principle which will show why the atoms should tend to their general centre of irradiation with forces inversely proportional to the squares of the distances, will be admitted as satisfactorily accounting, at the same time, for the tendency, according to the same law, of these atoms each to each: – for the tendency to the centre is merely the tendency each to each, and not any tendency to a centre as such. –Thus it will be seen, also, that the establishment of my propositions would involve no necessity of modification in the terms of the Newtonian definition of Gravity, which declares that each atom attracts each other atom and so forth, and declares this merely; but (always under the supposition that what I propose be, in the end, admitted) it seems СКАЧАТЬ
