Ralph Waldo Emerson on wisdom

It is one of the blessings of old friends that you can afford to be stupid with them.

The only way to have a friend is to be one.

What you do speaks so loudly that I cannot hear what you say.

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.
