“...a friend of mankind with shaky moral foundation is a cannibal of mankind, to say nothing of his vainglory; insult the vainglory of one of these numberless friends of mankind, and he is ready at once to set fire to the four corners of the world out of petty vengence”

“We've already had Malthus, the friend of humanity. But the friend of humanity with shaky moral principles is the devourer of humanity, to say nothing of his conceit; for, wound the vanity of any one of these numerous friends of humanity, and he's ready to set fire to the world out of petty revenge—like all the rest of us, though, in that, to be fair; like myself, vilest of all, for I might well be the first to bring the fuel and run away myself.”

“I love mankind, he said, "but I find to my amazement that the more I love mankind as a whole, the less I love man in particular.”

“The only gain of civilisation for mankind is the greater capacity for variety of sensations - and absolutely nothing more.”

“The vast mass of mankind is mere material, and only exists in order by some great effort, by some mysterious process, by means of some crossing of races and stocks, to bring into the world at last perhaps one man out of a thousand with a spark of independence.”

“[The Devil] In my opinion, there is no need to destroy anything, one needs only destroy the idea of God in mankind, that's where the business should start! One should begin with that, with that--oh, blind men, of no understanding! Once mankind has renounced God, one and all (and I believe that this period, analogous to the geological periods, will come), then the entire old world view will fall of itself, without antrhopophagy, and, above all, the entire former morality, and everything will be new. People will come together in order to take from life all that it can give, but, of course, for happiness and joy in this world only. Man will be exalted with the spirit of the divine, tatanic pride, and the man-god will appear. Man, his will and his science no longer limited, conquering nature every hour, will thereby every hour experience such lofty delight as will replace for him all his former hopes of heavenly delight. Each will know himself utterly mortal, without resurrection, and will accept death proudly and calmly, like a god. Out of pride he will understand that he should not murmur against the momentariness of life, and he will love his brother then without any reward. Love will satisfy only the moment of life, but the very awareness of its momentariness will increase its fire, inasmuch as previously it was diffused in hopes of an eternal love beyond the grave.”

“Is it true that you insisted you knew no difference in beauty between some brutal sensual stunt and any great deed, even the sacrifice of life for mankind? Is it true that you found a coincidence in beauty, a sameness of pleasure at both poles?...You married out of a passion for torture, out of a passion for remorse, out of moral sensuality.”
