“We do not like to be robbed of an enemy; we want someone to hate when we suffer. It is so depressing to think that we suffer because we are fools; yet, taking mankind in the mass, that is the truth.”

“We know very little, and yet it is astonishing that we know so much, and still more astonishing that so little knowledge can give us so much power.”

“In the part of this universe that we know there is great injustice, and often the good suffer, and often the wicked prosper, and one hardly knows which of those is the more annoying.”

“Truth is for the gods; from our human point of view, it is an ideal, towards which we can approximate, but which we cannot hope to reach.”

“We have in fact, two kinds of morality, side by side: one which we preach, but do not practice, and another which we practice, but seldom preach.”

“In the modern world, those whom we effectively hate are distant groups, especially foreign nations. We conceive them abstractly, and deceive ourselves into the belief that acts which are really embodiments of hatred are done from love or justice or some lofty motive. Only a large measure of skepticism can tear away the veils which hide this truth from us.”

“Love is wise; hatred is foolish. In this world, which is getting more and more closely interconnected, we have to learn to tolerate each other, we have to learn to put up with the fact that some people say things that we don't like. We can only live together in that way. But if we are to live together, and not die together, we must learn a kind of charity and a kind of tolerance, which is absolutely vital to the continuation of human life on this planet.”
