Real knowledge is to know the extent of one's ignorance.

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

A child educated only at school is an uneducated child.

It is not enough for the teacher to love the child. She must first love and understand the universe. She must prepare herself, and truly work at it.

Suddenly degrees aren't worth anything. Isn't that true? When I was a student, if you had a degree, you had a job. If you didn't have a job it's because you didn't want one. And I didn't want one, frankly.

Never help a child with a task at which he feels he can succeed.

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.

Reading without reflecting is like eating without digesting.

If the facts don't fit the theory, change the facts.

Science is what we have learned about how to keep from fooling ourselves.

Common sense is the collection of prejudices acquired by age eighteen.

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

Make it a rule never to give a child a book you would not read yourself.

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

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

To educate a person in the mind but not in morals is to educate a menace to society.

Reading furnishes the mind only with materials of knowledge; it is thinking that makes what we read ours.

Many much-learned men have no intelligence.

I cannot teach anybody anything. I can only make them think

The fullness of knowledge only comes through the awareness of ignorance.
