Wherever smart people work, doors are unlocked.

Ignorance is no excuse, it's the real thing.

Don't leave home without your sword - your intellect.

To be able to fill leisure intelligently is the last product of civilization.

When I see a dolphin, I know it's just as smart as I am.

Remember to be as smart as you are.

Intelligence is not a science.

Intellectuals are too sentimental for me.

The function of education is to teach one to think intensively and to think critically. Intelligence plus character - that is the goal of true education.

The true sign of intelligence is not knowledge but imagination.
