I have nothing to say against this maxim. Evil is always attributed to moral causes, and not always to physical causes. Here I observe simply that if I could not prevent the sin of others except by committing a sin myself, I should be justified in permitting it, and I should not be accessary thereto, or its moral cause. In God, every fault would represent a sin; it would be even more than sin, for it would destroy Divinity. And it would be a great fault in him not to choose the best. I have said so many times. He would then prevent sin by something worse than all sins. 132. XVII. 'It is all the same whether one employ a necessary cause, or employ a free cause while choosing the moments when one knows it to be determined. If I imagine that gunpowder has the power to ignite or not to ignite when fire touches it, and if I know for certain that it will be disposed to ignite at eight o'clock in the morning, I shall be just as much the cause of its effects if I apply the fire to it at that hour, as I should be in assuming, as is the case, that it is a necessary cause. [203] For where I am concerned it would no longer be a free cause. I should be catching it at the moment when I knew it to be necessitated by its own choice. It is impossible for a being to be free or indifferent with regard to that to which it is already determined, and at the time when it is determined thereto. All that which exists exists of necessity while it exists. [Greek: To einai to on hotan ei, kai to me einai hotan me ei, ananke.] "Necesse est id quod est, quando est, esse; et id quod non est, quando non est, non esse": Arist., _De Interpret._, cap. 9. The Nominalists have adopted this maxim of Aristotle. Scotus and sundry other Schoolmen appear to reject it, but fundamentally their distinctions come to the same thing. See the Jesuits of Coimbra on this passage from Aristotle, p. 380 _et seq._)' This maxim may pass also; I would wish only to change something in the phraseology. I would not take 'free' and 'indifferent' for one and the same thing, and would not place 'free' and 'determined' in antithesis. One is never altogether indifferent with an indifference of equipoise; one is always more inclined and consequently more determined on one side than on another: but one is never necessitated to the choice that one makes. I mean here a _necessity_ absolute and metaphysical; for it must be admitted that God, that wisdom, is prompted to the best by a _moral_ necessity. It must be admitted also that one is necessitated to the choice by a hypothetical necessity, when one actually makes the choice; and even before one is necessitated thereto by the very truth of the futurition, since one will do it. These hypothetical necessities do no harm. I have spoken sufficiently on this point already.
