Not I, but the city teaches.

A painter will paint a cobbler, carpenter, or any other artist, though he knows nothing of their arts; and, if he is a good artist, he may deceive children or simple persons, when he shows them his picture of a carpenter from a distance, and they will fancy that they are looking at a real carpenter.

If he who does not know kept silent, discord would cease.

The Delphic Oracle said I was the wisest of all the Greeks. It is because that I alone, of all the Greeks, know that I know nothing.

The only true wisdom is in knowing you know nothing.

An envious man waxeth lean with the fatness of his neighbors. Envy is the daughter of pride, the author of murder and revenge, the beginner of secret sedition and the perpetual tormentor of virtue. Envy is the filthy slime of the soul; a venom, a poison, or quicksilver which consumeth the flesh and drieth up the marrow of the bones.

You too must be of good hope as regards death, gentlemen of the jury, and keep this one truth in mind, that a good man cannot be harmed either in life or in death, and that his affairs are not neglected by the gods. What has happened to me now has not happened of itself, but it is clear to me that it was better for me to die now and to escape from trouble. That is why my divine sign did not oppose me at any point. So I am certainly not angry with those who convicted me, or with my accusers. Of course that was not their purpose when they accused and convicted me, but they thought they were hurting me, and for this they deserve blame.
