To begin with unlimited freedom is to end with unlimited despotism.

Intelligence alone is not nearly enough when it comes to acting wisely.

I know you'll probably get angry with me for that, shout, stamp your feet: "speak just for yourself and your miseries in the underground, and don't go saying 'we all.'" Excuse me, gentleman, but I am not justifying myself with this allishness. As far as I myself am concerned, I have merely carried to an extreme in my life what you have not dared to carry even halfway, and, what's more, you've taken your cowardice for good sense, and found comfort in thus deceiving yourselves. So that I, perhaps, come out even more "living" than you.

To care only for well-being seems to me positively ill-bred. Whether it’s good or bad, it is sometimes very pleasant, too, to smash things.

But it's precisely in this cold, loathsome half-despair, half-belief, in this deliberate burying of yourself underground for forty years out of sheer pain, in this assiduously constructed, and yet somewhat dubious hopelessness, in all this poision of unfulfilled desires turned inward, this fever of vacillations, of resolutions adopted for eternity, and of repentances a moment later that you find the very essence of that strange, sharp pleasure.

My God, but what do I care about the laws of nature and arithmatic if for some reason these laws and two times two is four are not to my liking?

And now I am eking out my days in my corner, taunting myself with the bitter and entirely useless consolations that an intelligent man cannot seriously become anything; that only a fool can become something. Yes, sir, an intelligent nineteenth-century man must be, is morally bound to be, an essentially characterless creature; and a man of character, a man of action - an essentially limited creature. This is my conviction at the age of forty. I am forty now, and forty years - why, it is all of a lifetime, it is the deepest of old age. Living past forty is indecent, vulgar, immoral!
