That men do not learn very much from the lessons of history is the most important of all the lessons that history has to teach.

It is beyond a doubt that all our knowledge begins with experience.

Learn as though you would never be able to master it; hold it as though you would be in fear of losing it.

You can never learn less, you can only learn more.

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

Study without desire spoils the memory, and it retains nothing that it takes in.

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

All knowledge that the world has ever received comes from the mind; the infinite library of the universe is in our own mind.

A little knowledge is a dangerous thing. So is a lot.

A cynic is a man who knows the price of everything, and the value of nothing.

Education is an admirable thing, but it is well to remember from time to time that nothing that is worth knowing can be taught.

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

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.

If one cannot enjoy reading a book over and over again, there is no use in reading it at all.

Opinion is the medium between knowledge and ignorance.

The man who does not read good books has no advantage over the man who can't read them.

The whole of science is nothing more than a refinement of everyday thinking.

A witty saying proves nothing.

With educated people, I suppose, punctuation is a matter of rule; with me it is a matter of feeling. But I must say I have great respect for the semi-colon; it's a useful little chap.

One test of the correctness of educational procedure is the happiness of the child.

Reading without reflecting is like eating without digesting.
