From Notes from Underground:
Shower him with all earthly blessings, drown him in happiness completely, over his head, so that only bubbles pop up on the surface of happiness, as on water; give him such economic satisfaction that he no longer has anything left to do at all except sleep, eat gingerbread, and worry about the noncessation of world history — and it is here, just here, that he, this man, out of sheer ingratitude, out of sheer lampoonery, will do something nasty. He will even risk his gingerbread, and wish on purpose for the most pernicious nonsense, the most non-economical meaninglessness, solely in order to mix into all this positive good sense his own pernicious fantastical element. It is just his fantastic dreams, his vulgar folly that he will desire to retain, simply in order to prove to himself–as though that were so necessary—that men still are men and not the keys of a piano.
And on our drive to “live at our own sweet foolish will“:
Man really is stupid, phenomenally stupid. That is, he’s by no means stupid, but rather he’s so ungrateful that it would be hard to find the likes of him. I, for example, would not be the least bit surprised if suddenly, out of the blue, amid the universal future reasonableness, some gentleman of ignoble, or, better, of retrograde and jeering physiognomy, should emerge, set his arms akimbo, and say to us all: “Well, gentlemen, why don’t we reduce all this reasonableness to dust with one good kick, for the sole purpose of sending all these logarithms to the devil and living once more according to our own stupid will!”
