If it is assumed that one of them is at one time greater than the other and stood in relation to the smaller precisely as greater, then what was said above applies, namely that the greater would gain absolute predominance and the smaller would vanish; it is as something vanishing, lacking support, that the latter is being posited, and nothing is altered in this determination by supposing that the vanishing happens only gradually, or that it decreases only as much as the other increases, for the one force that increases is destroyed together with the other that decreases, since it is what it is only to the extent that the other is what it is.
