Euripides on wisdom

When good men die their goodness does not perish, but lives though they are gone. As for the bad, all that was theirs dies and is buried with them.

There is one thing alone that stands the brunt of life throughout its course: a quiet conscience.

‘Twas but my tongue, ‘twas not my soul that swore.

The only true wisdom is in knowing you know nothing.

Socrates470–399 BC

By three methods we may learn wisdom: First, by reflection, which is noblest; Second, by imitation, which is easiest; and third by experience, which is the bitterest.

Confucius551–479 BC

True wisdom comes to each of us when we realize how little we
understand about life, ourselves, and the world around us.
