Cicero on wisdom

A room without books is like a body without a soul.

In the very books in which philosophers bid us scorn fame, they inscribe their names.

Wise men are instructed by reason; men of less understanding, by experience; the most ignorant, by necessity; the beasts, by nature.

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.
