“Nevertheless I would be a hypocrite not to anticipate that the good intentions I brought to The Prince will also be the root of some other man's evil, if only because the way to the house of the Devil is the same for the good man and the bad - and the journey just as necessary for them both. The times change, but the nature of men does not.”
“[The Devil] Mephistopheles, when he comes to Faust, testifies of himself that he desires evil, yet does only good. Well, let him do as he likes, it's quite the opposite with me. I am perhaps the only man in all of nature who loves the truth and sincerely desires good.”
“The only thing necessary for the continuance of evil is for a good man to do nothing.”
“Does God want goodness or the choice of goodness? Is a man who chooses to be bad perhaps in some way better than a man who has the good imposed upon him?”
“Good works do not make a good man, but a good man does good works; evil works do not make a wicked man, but a wicked man does evil works.”
“Man lives only to learn. And if he learns it is because it is the nature of his lot, for good or bad.”
