Edmund Burke on wisdom

All that is required for evil to prevail is for good men to do nothing.

No passion so effectually robs the mind of all its powers of acting and reasoning as fear.

The people never give up their liberties but under some delusion.

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.
