To be effective, morality has to be reasoned (or worked out). To want ("vouloir", Fr.) to repress evil only by coercion, and to obtain morality by a sort of training with the help of constraint, without motivating it from within, is to make it an unnatural result, devoided of lastind value.
The Law is not in fault, but our evil and wicked nature; even as a heap of lime is still and quiet until water is poured on it, but then it begins to smoke and burn, not from the fault of the water, but from the nature of the lime, which will not endure it.
In the real world in which we live, you always have to choose between evils. And in choosing between evils, you have to have moral criteria for how to make those choices.
Everything is deception: seeking the minimum of illusion, keeping within the ordinary limitations, seeking the maximum. In the first case one cheats the Good, by trying to make it too easy for oneself to get it, and the Evil by imposing all too unfavorable conditions of warfare on it. In the second case one cheats the Good by keeping as aloof from it as possible, and the Evil by hoping to make it powerless through intensifying it to the utmost.
For every life and every act consequence of good and evil can be shown and as in time results of many deeds are blended so good and evil in the end become confounded.
