“Then Prometheus, in his perplexity as to what preservation he could devise, stole from Hephaestus and Athena wisdom in the arts together with fire -- since by no means without fire could it be acquired or helpfully used by any -- and he handed it there and then as a gift to man.”

“But the truth is, O men of Athens, that God only is wise; and by his answer he intends to show that the wisdom of men is worth little or nothing; he is not speaking of Socrates, he is only using my name by way of illustration, as if he said, He, O men, is the wisest, who, like Socrates, knows that his wisdom is in truth worth nothing.”

“Noticing that, he made a trail of the ring, to see if it had that power; and he found that whenever he turned the collet inside, he was invisible, when he turned it outside, visible. After he found this out he managed to be appointed one of the messengers to the king; when he got there, he seduced the king's wife, and with her set upon the king, and killed him, and seized the empire. Then if there could be two such rings, and if the just man put one on and the unjust the other, no one, as it would be thought, would be so adamantine as to abide in the practice of justice, no one could endure to hold back from another's goods and not to touch, when it was in his power to take what he would even out of the market without fear, and to go into any house and lie with anyone he wished, and to kill or set free from prison those he might wish, and to do anything else in the world like a very god. And in doing so he would do just the same as the other; both would go the same way. Surely one would call this a strong proof that no one is just willingly but only under a strong compulsion, believing that it is not a good to him personally; since wherever each thinks he will be able to do injustice, he does injustice.”

“Any one who has common sense will remember that the bewilderments of the eyes are of two kinds, and arise from two causes, either from coming out of the light or from going into the light, which is true of the mind's eye, quite as much as of the bodily eye; and he who remembers this when he sees any one whose vision is perplexed and weak, will not be too ready to laugh; he will first ask whether that soul of man has come out of the brighter life, and is unable to see because unaccustomed to the dark, or having turned from dakness to the day is dazzled by excess of light. And he will count the one happy in his condition and state of being, and he will pity the other; or, if he have a mind to laugh at the soul which comes from below into the light, there will be more reason in this than in the laugh which greets him who returns from above out of the light into the den. (Included in the introduction to "Flowers for Algernon" by Daniel Keyes)”

“He could not harm me, for I do not think it is permitted that a better man be harmed by a worse”

“Rather I think that a man who ... is willing ... to value learning as long as he lives, not supposing that old age brings him wisdom of itself, will necessarily pay more attention to the rest of his life.”

“Imagine that the keeper of a huge, strong beast notices what makes it angry, what it desires, how it has to be approached and handled, the circumstances and the conditions under which it becomes particularly fierce or calm, what provokes its typical cries, and what tones of voice make it gentle or wild. Once he's spent enough time in the creature's company to acquire all this information, he calls it knowledge, forms it into a systematic branch of expertise, and starts to teach it, despite total ignorance, in fact, about which of the creature's attitudes and desires is commendable or deplorable, good or bad, moral or immoral. His usage of all these terms simply conforms to the great beast's attitudes, and he describes things as good or bad according to its likes and dislikes, and can't justify his usage of the terms any further, but describes as right and good the things which are merely indispensable, since he hasn't realised and can't explain to anyone else how vast a gulf there is between necessity and goodness.”
