Gravity is not proportional to mass (for what is this mass but an abstraction of the specific gravity which you have hypostatized?); but, conversely, the mass of a body is only the expression of the momentum, with which the antithesis in it cancels itself.
(d) By the foregoing, the construction of matter in general is completed, but not the construction of specific difference in matter.
That which all the matter of B, C, &c., in relation to A has common under it, is the difference which is not cancelled by A, and which again cancels itself in part in B and C—hence, therefore, the gravity mediated by that difference.
What distinguishes B and C from A therefore, is the difference which is not cancelled by A, and which becomes the condition of gravity in the case of B and C.—Similarly, what distinguishes C from B (if C is a product subordinate to B), is the difference which is not cancelled by B, and which is again carried over to C. Gravity, therefore, is not the same thing for the higher and for the subaltern world-bodies, and there is as much variety in the central forces as in the conditions of attraction.
The means whereby, in the products A, B, C, which, in so far as they are opposed to each other, represent products absolutely homogeneous [because the antithesis is the same for the whole product,] another difference of individual products is possible, is the possibility of a difference of relation between the factors in the cancelling, so that, for example, in X, the positive factor, and in Y, the negative factor, has the preponderance, (thus rendering the one body positively, and the other negatively, electric).—All difference is difference of electricity.[[34]]
(e) That the identity of matter is not absolute identity, but only indifference, can be proved from the possibility of again cancelling the identity, and from the accompanying phenomena.[[35]] We may be allowed, for brevity’s sake, to include this recancelling, and its resultant phenomena under the expression dynamical process, without, of course, affirming decisively whether anything of the sort is everywhere actual.
Now there will be exactly as many stages in the dynamical process as there are stages of transition from difference to indifference.
(α) The first stage will be marked by objects in which the reproduction and recancelling of the antithesis at every step is still itself an object of perception.
The whole product is reproduced anew at every step,[[36]] that is, the antithesis which cancels itself in it, springs up afresh every moment; but this reproduction of difference loses itself immediately in universal gravity;[[37]] this reproduction, therefore, can be perceived only in individual objects, which seem to gravitate towards each other; since, if to the one factor of an antithesis is offered its opposite (in another) both factors become heavy with reference to each other, in which case, therefore, the general gravity is not cancelled, but a special one occurs within the general.—An instance of such a mutual relation between two products, is that of the earth and the magnetic needle, in which is distinguished the continual recancelling of indifference in gravitation towards the poles[[38]]—the continual sinking back into identity[[39]] in gravitation towards the universal indifference-point. Here, therefore, it is not the object, but the being-reproduced of the object that becomes object.[[40]]
(β) At the first stage, in the identity of the product, its duplicity again appears; at the second, the antithesis will divide up and distribute itself among different objects (A and B). From the fact that the one factor of the antithesis attained a relative preponderance in A, the other in B, there will arise, according to the same law as in α, a gravitation of the factors toward each other, and so a new difference, which, when the relative equiponderance is restored in each, results in repulsion[[41]]—(change of attraction and repulsion, second stage in which matter is seen)—electricity.
