“I may begin by laying down as a principle that ‘all pain of human or rational beings is to be avoided’; and then afterwards may be led to enunciate the wider rule that ‘all pain is to be avoided’; it being made evident to me that the difference of rationality between two species of sentient beings is no ground for establishing a fundamental ethical distinction between their respective pains.”

“The choice before human beings, is not, as a rule, between good and evil but between two evils.”

Context: The choice before human beings, is not, as a rule, between good and evil but between two evils. You can let the Nazis rule the world: that is evil; or you can overthrow them by war, which is also evil. There is no other choice before you, and whichever you choose you will not come out with clean hands.

Context: “Humanity has evolved—as far as it has evolved,” continued the old priest, “with no thanks to its predecessors or itself. Evolution brings human beings. Human beings, through a long and painful process, bring humanity.”
