Civilization is a race between disaster and education.

Many much-learned men have no intelligence.

Courage, conviction and confidence.

Science is a rising force, It is creating a new world about us. It needs to be watched and pressed into service, and in any case, it would be courting disaster to ignore it.

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

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.

We could never learn to be brave and patient, if there were only joy in the world

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

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

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

Knowledge, Action, Devotion are complementary to each other.

When I am attacked by gloomy thoughts, nothing helps me so much as running to my books. They quickly absorb me and banish the clouds from my mind.

Know what you are talking about.

A man who has never gone to school may steal a freight car; but if he has a university education, he may steal the whole railroad.

I decided to teach because I think that any person who studies philosophy has to be involved actively.

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

There is no authority who decides what is a good idea.

I cannot live without books.

Seek knowledge from the cradle to the grave.
