Jiddu Krishnamurti on wisdom

Where there is fear there is aggression.

Only the free mind knows what Love is.

Without love the acquisition of knowledge only increases confusion and leads to self-destruction.

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.
