Edwards is far from being the only necessitarian who has fallen into the error of identifying the sensibility with the will; thus reducing his doctrine to an unassailable truism. In his famous controversy with Clarke, Leibnitz has done the same thing. “Thus,” says he, “in truth, the motives comprehend all the dispositions which the mind can have to act voluntarily; for they include not only reasons, but also the inclinations and passions, or other preceding impressions. Wherefore if the mind should prefer a weak inclination to a strong one, it would act against itself, and otherwise than it is disposed to act.”

Now is it not wonderful, that so profound a thinker, and so acute a metaphysician, as Leibnitz, should have supposed that he was engaged in a controversy to show that the mind never acts otherwise than it acts; that it never acts against itself? Having reduced his doctrine to this truism, he says, this “shows that the author's notions, contrary to mine, are superficial, and appear to have no solidity in them, when they are well considered.” True, the notions of Clarke were superficial, and worse than superficial, if he supposed that the mind ever acts contrary to its act, or otherwise than it really acts. But Clarke distinguished between the disposition and the will.

In like manner Thummig, the disciple of Leibnitz, has the following language, as quoted by Sir William Hamilton: “It is to philosophize very crudely concerning mind, and to image everything in a corporeal manner, to conceive that actuating reasons are something external, which make an impression on the mind, and to distinguish motives from the active principle itself.” Now this language, it seems, is found in Thummig's defence of the last paper of Leibnitz (who died before the controversy was terminated) against the answer of Clarke. But, surely, if it is a great mistake, as the author insists it is, to distinguish motives from the active principle itself; then to say that the active principle is determined by motives, is to say that the active principle is determined by itself. And having reached this point, the disciple of Leibnitz finds himself planted precisely on the position he had undertaken to overthrow, namely, that the will is determined by itself. And again, if it be wrong to distinguish the motive from the active principle itself, then to say that the active principle never departs from the motive, is to affirm that a thing is always as itself.

The great service which a false psychology has rendered to the cause of necessity is easily seen. For having identified an act of the will with a state of the sensibility, which is universally conceived to be necessitated, the necessitarian is delivered from more than half his labours. By merging a phenomenon or manifestation of the will in a state of the sensibility, it seems to lose its own characteristic, which is incompatible with the scheme of necessity, and to assume the characteristic of feeling, which is perfectly reconcilable with it; nay, which demands the scheme of necessity to account for its existence. Thus, the [pg 142] system of necessity is based on a false psychology, on which it has too securely stood from the earliest times down to the present day. But the stream of knowledge, ever deepening and widening in its course, has been gradually undermining the foundations of this dark system.

Section II.

The scheme of necessity is directed against a false issue.

As we have seen in the last section, the argument of the necessitarian is frequently directed against a false issue; but the point is worthy of a still more careful consideration.

We shall never cease to admire the logical dexterity with which the champions of necessity assail and worry their adversaries. They have said, in all ages, that “nothing taketh beginning from itself;” but who ever imagined or dreamed of so wild an absurdity? It is conceded by all rational beings. Motion taketh not beginning from itself, but from action; action taketh not beginning from itself, but from mind; and mind taketh not beginning from itself, but from God. It is false, however, to conclude that because nothing taketh beginning from itself, it is brought to pass “by the action of some immediate agent without itself.” The motion of body, as we have seen, is produced by the action of some immediate agent without itself; but the action of mind is produced, or brought to pass, by no action at all. It taketh beginning from an agent, and not from the action of an agent. This distinction, though so clearly founded in the nature of things, is always overlooked by the logic of the necessitarian. They might well adopt the language of Bacon, that the subtilty of nature far surpasseth that of our logic.

Hobbes was content to rest on a simple statement of the fact, that nothing can produce itself; but it is not every logician who is willing to rely on the inherent strength of such a position. Ask a child, Did you make yourself? and the child will answer, No. Propound the same question to the roving savage, or to the man of mere common sense, and he will also answer, No. Appeal to the universal reason of man, and the same emphatic No, will come up from its profoundest depths. But your redoubtable logicians are not satisfied to rely on such testimony [pg 143] alone: they dare not build on such a foundation unless it be first secured and rendered firm by the aid of the syllogistic process. I know “I did not make myself,” says Descartes, “for if I had made myself, I should have given myself every perfection.” Now this argument in true syllogistic form stands thus: If I had made myself, I should have endowed myself with every perfection; I am not endowed with every perfection; therefore I did not make myself. Surely, after so clear a process of reasoning, no one can possibly doubt the proposition that Descartes did not make himself! In the same way we might prove that he did not make his own logic: for if he had made his logic, he would have endowed it with every possible perfection; but it is not endowed with every possible perfection, and therefore he did not make it.
