Understand that for every rule which I have mentioned from the Quran, the Devil has one to match it, which he puts beside the proper rule to cause error.
Every man, however obscure, however far removed from the general recognition, is one of a group of men impressible for good, and impressible for evil, and it is in the nature of things that he cannot really improve himself without in some degree improving other men.
He that will not apply new remedies, must expect new evils: for Time is the greatest innovator: and if Time, of course, alter things to the worse, and wisdom and counsel shall not alter them to the better, what shall be the end?.
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.
So far as we are human, what we do must be either evil or good: so far as we do evil or good, we are human: and it is better, in a paradoxical way, to do evil than to do nothing: at least we exist.
