Miyamoto Musashi on wisdom

Think lightly of yourself and deeply of the world.

Respect Buddha and the gods without counting on their help.

Do not let yourself be guided by the feeling of lust or love.

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.
