“Pleasure is the bait of sin”

“if you are willing to reflect on the courage and moderation of other people, you will find them strange...they all consider death a great evil...and the brave among them face death, when they do, for fear of greater evils...therefore, it is fear and terror that make all men brave, except for philosophers. yet it is illogical to be brave through fear and cowardice...what of the moderate among them? is their experience not similar?...they master certain pleasures because they are mastered by others...i fear this is not the right exchange to attain virtue, to exchange pleasures for pleasures, pains for pains, and fears for fears, the greater for the less like coins, but that they only valid currency for which all these things should be exchanged is wisdom.”

“What a strange thing that which men call pleasure seems to be, and how astonishing the relation it has with what is thought to be its opposite, namely pain! A man cannot have both at the same time. Yet if he pursues and catches the one, he is almost always bound to catch the other also, like two creatures with one head.”

“All the same, we ought to point out that if the kinds of poetry and representation which are designed merely to give pleasure can come up with a rational argument for their inclusion in a well-governed community, we'd be delighted -- short of compromising the truth as we see it, which wouldn't be right -- to bring them back from exile: after all, we know from our own experience all about their spell. I mean haven't you ever fallen under the spell of poetry, Glaucon, especially when the spectacle is provided by Homer?”

“To conquer oneself is the best and noblest victory; to be vanquished by one's own nature is the worst and most ignoble defeat.”

“I am the wisest man alive, for I know one thing, and that is that I know nothing.”

“I really do not know, Socrates, how to express what I mean. For somehow or other our arguments, on whatever ground we rest them, seem to turn round and walk away from us.”
