“I suspect gentlemen, that you're regarding me with pity; you keep repeating to me that an enlightened and cultured man -- such as, in short, as the man of the future will be -- cannot knowingly desire anything unprofitable for himself -- that that's mathematics. I agree totally that it really is mathematics. But I repeat to you for the hundredth time: there is only one case, only one, when a man can intentionally and consciously desire for himself even what is harmful and stupid, even what is extremely stupid: namely, in order to have the right to desire for himself even what is extremely stupid and not be constrained by the obligation to desire for himself only what is intelligent.”

“[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.”

“"Ha! ha! ha! But after all, if you like, in reality there is not such thing as choice," you will interrupt with a laugh. "Science has even now succeeded in analysing man to such an extent that we know already that choice and what is called freedom of will are nothing other than--"Wait, gentlemen, I meant to begin with that myself. I admit I was even frightened. I was just going to shout that after all the devil only knows what choice depends on, and that perhaps that is a very good thing, but I remembered the teaching of science-- and pulled myself up. And here you have begun to speak. After all, really, well, if someday they truly discover a formula for all our desires and caprices-- that is, an explanations of what they depend upon, by what laws they arise, just how they develop, what they are aiming at in one case or another and so on, and so on, that is, a real mathematical formula-- then, after all, man would most likely at once stop to feel desire, indeed, he will be most certain to. For who would want to choose by rule? Besides, he will at once be transformed from a human being into an organ stop or something of the sort; for what is a man without desire, without free will and without choice, if not a stop in an organ? What do you think? Let us consider the probability-- can such a thing happen or not?”

“I am a wicked man... But do you know, gentlemen, what was the main point about my wickedness? The whole thing, precisely was, the greatest nastiness precisely lay in my being shamefully conscious every moment, even in moments of the greatest bile, that I was not only not a wicked man but was not even an embittered man, that I was simply frightening sparrows in vain, and pleasing myself with it.”

“A wise man can't seriously make himself anything, only a fool makes himself anything.”

“There are certain things in a man's past which he does not divulge to everybody but, perhaps, only to his friends. Again there are certain things he will not divulge even to his friends; he will divulge them perhaps only to himself, and that, too, as a secret. But, finally, there are things which he is afraid to divulge even to himself, and every decent man has quite an accumulation of such things in his mind. I can put it even this way: the more decent a man is, the larger will the number of such things be.”

“Now I'm living out my life in a corner, trying to console myself with the stupid, useless excuse that an intelligent man cannot turn himself into anything, that only a fool can make anything he wants out of himself.”
