Friedrich Nietzsche on wisdom

Blessed are the forgetful: for they get the better even of their blunders.

A few hours of mountain climbing turn a villain and a saint into two rather equal creature. Exhaustion is the shortest way to equality and fraternity, and liberty is added eventually by sleep.

What is happiness? The feeling that power is growing, that resistance is overcome.

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.
