Go where he will, the wise man is at home.

Ralph Waldo Emerson

Not by age but by capacity is wisdom acquired.

Titus Maccius Platus

Wisdom is perishable. Unlike information or knowledge, it cannot be stored in a computer or recorded in a book. It expires with each passing generation.

Sid Taylor

You can tell whether a man is clever by his answers. You can tell whether a man is wise by his questions.

Nagib Mahfuz

He is no wise man who will quit a certainty for an uncertainty.

Samuel Johnson
