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

“In any case civilisation has made mankind if not more bloodthirsty, at least more vilely, more loathsomely bloodthirsty.”

“Civilization merely develops man's capacity for a greater variety of sensations, and... absolutely nothing else. And through the development of this capacity, man may yet come to find pleasure in the spilling of blood.”

“...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”

“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.”

“You see, gentlemen, reason is an excellent thing, there's no disputing that, but reason is nothing but reason and satisfies only the rational side of man's nature, while will is a manifestation of the whole life, that is, of the whole human life including reason and all the impulses. And although our life, in this manifestation of it, is often worthless, yet it is life and not simply extracting square roots. Here I, for instance, quite naturally want to live, in order to satisfy all my capacities for life, and not simply my capacity for reasoning, that is, not simply one twentieth of my capacity for life. What does reason know? Reason only knows what it has succeeded in learning (some things, perhaps, it will never learn; this is a poor comfort, but why not say so frankly?) and human nature acts as a whole, with everything that is in it, consciously or unconsciously, and, even if it goes wrong, it lives.”

“How can you tell a man there’s nothing to do? I can’t imagine a situation in which there could ever be nothing to do! Do it for mankind and don’t worry about the rest. There’s so much to do that a lifetime won’t be enough, if you look around attentively.”
