“Nobody is qualified to become a statesman who is entirely ignorant of the problem of wheat.”

“The only good is knowledge and the only evil is ignorance.”

“I know nothing except the fact of my ignorance.”

“There is only one good, knowledge, and one evil, ignorance.”

“By all means marry; if you get a good wife, you’ll become happy; if you get a bad one, you’ll become a philosopher.”

“And a thing is not seen because it is visible, but conversely, visible because it is seen; nor is a thing led because it is in the state of being led, or carried because it is in the state of being carried, but the converse of this. And now I think, Euthyphro, that my meaning will be intelligible; and my meaning is, that any state of action or passion implies previous action or passion. It does not become because it is becoming, but it is in a state of becoming because it becomes; neither does it suffer because it is in a state of suffering, but it is in a state of suffering because it suffers. Do you not agree?”

“The mind is everything; what you think you become”
