Opinion is the medium between knowledge and ignorance.

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

Books are as useful to a stupid person as a mirror is useful to a blind person.

A little knowledge that acts is worth infinitely more than much knowledge that is idle.

It is better to know how to learn than to know.

If you can't explain it simply, you don't understand it well enough.

God created man in His own image, says the Bible; philosophers reverse the process: they create God in theirs.

Any knowledge that doesn't lead to new questions quickly dies out: it fails to maintain the temperature required for sustaining life.

Imagination is more important than knowledge.

You can never be overdressed or overeducated.

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.

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.

If I could explain it to the average person, I wouldn't have been worth the Nobel Prize.

A child educated only at school is an uneducated child.

Education is a human right with immense power to transform. On its foundation rest the cornerstones of freedom, democracy and sustainable human development.

If there were no bad people, there would be no good lawyers.

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

Don't worry that children never listen to you; worry that they are always watching you.

Necessity is the mother of invention.

If you want the present to be different from the past, study the past.

A thought is an idea in transit.
