Francis Bacon on wisdom

A prudent question is one-half of wisdom.

It is impossible to love and to be wise.

Never exaggerate your faults. Your friends will attend to that.

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.
