We do not know what education can do for us, because we have never tried it.

...The task is overwhelming, and the chance is slight. We must take the chance or die.

Education is a kind of continuing dialogue, and a dialogue assumes different points of view.

This is a do-it-yourself test for paranoia: you know you've got it when you can't think of anything that's your fault.

The policy of repression of ideas cannot work and never has worked.

Whenever the urge to exercise comes upon me, I lie down for a while and it passes.

It must be remembered that the purpose of education is not to fill the minds of students with facts... it is to teach them to think.
