“I don't need a friend who changes when I change and who nods when I nod; my shadow does that much better.”

“Such contentedness and change of view in regard to every kind of life does the infusion of reason bring about. When Alexander heard from Anaxarchus of the infinite number of worlds, he wept, and when his friends asked him what was the matter, he replied, "Is it not a matter for tears that, when the number of worlds is infinite, I have not conquered one?”

“When Alexander saw the breadth of his domain, he wept for there were no more worlds to conquer. (Technically a misquote, but I like the misquote better)”

“When a man's eyes are sore his friends do not let him finger them, however much he wishes to, nor do they themselves touch the inflammation: But a man sunk in grief suffers every chance comer to stir and augment his affliction like a running sore; and by reason of the fingering and consequent irritation it hardens into a serious and intractable evil.”

“I, for my part, wonder of what sort of feeling, mind or reason that man was possessed who was first to pollute his mouth with gore, and to allow his lips to touch the flesh of a murdered being: who spread his table with the mangled forms of dead bodies, and claimed as daily food and dainty dishes what but now were beings endowed with movement, perception and with voice.…but for the sake of some little mouthful of flesh, we deprive a soul of the sun and light, and of that portion of life and time it had been born in to the world to enjoy.”

“Many things which cannot be overcome when they are together yieldthemselves up when taken little by little.”

“Know how to listen, and you will profit even from those who talk badly.”
