The alphabet will create forgetfulness in the learners' souls. They will trust the written characters and not remember themselves.

Not I, but the city teaches.

No one can teach, if by teaching we mean the transmission of knowledge, in any mechanical fashion, from one person to another. The most that can be done is that one person who is more knowledgeable than another can, by asking a series of questions, stimulate the other to think, and so cause him to learn for himself.

The easiest and noblest way is not to be crushing others, but to be improving yourselves.

The more I know, the more I know that I don't know.

Beware the barrenness of a busy life.

He is a man of courage who does not run away, but remains at his post and fights against the enemy.
