William Wordsworth on wisdom

We must be free or die, who speak the tongue
That Shakespeare spake; the faith and morals hold
Which Milton held.

To me the meanest flower that blows can give
Thoughts that do often lie too deep for tears.

And ‘t is my faith, that every flower
Enjoys the air it breathes.

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.
