Homer on wisdom

Who dares think one thing, and another tell,
My heart detests him as the gates of hell.

A glorious death is his
Who for his country falls.

Bird-signs!
Fight for your country⁠—that is the best, the only omen!

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.
