Imagination is the source of every form of human achievement. And it's the one thing that I believe we are systematically jeopardizing in the way we educate our children and ourselves.

I am indebted to my father for living, but to my teacher for living well.

Free the child's potential, and you will transform him into the world.

The idea is to try to give all the information to help others to judge the value of your contribution; not just the information that leads to judgment in one particular direction or another.

I cannot live without books.

Medicine is my lawful wife and literature my mistress; when I get tired of one, I spend the night with the other.

I don't look on poetry as closed works. I feel they're going on all the time in my head and I occasionally snip off a length.

No power and no treasure can outweigh the extension of our knowledge.

Imagination is more important than knowledge.

An investment in knowledge pays the best interest.

Evil being the root of mystery, pain is the root of knowledge.

What sculpture is to a block of marble, education is to a human soul.

Study hard what interests you the most in the most undisciplined, irreverent and original manner possible.

There is nothing more awful, insulting, and depressing than banality.

Investigate, educate and organize.

Learning never exhausts the mind.

Education is the kindling of a flame, not the filling of a vessel.

Intelligence plus character-that is the goal of true education.

If help and salvation are to come, they can only come from the children, for the children are the makers of men.

The first principle is that you must not fool yourself and you are the easiest person to fool.

Those who fail to learn the lessons of history are doomed to repeat them.
