Everybody needs one essential friend.

We can pay teachers a hundred thousand dollars a year, and we'll do nothing to improve our schools as long as we keep the A, B, C, D, F grading system.

No human being will work hard at anything unless they believe that they are working for competence.

To counter the avoidance of intellectual challenge and responsibility, we must reduce the domination of certainty in education.

When we label anyone 'bad', we will have more trouble dealing with him than if we could have settled for a lesser label.

I think education is both using and improving knowledge and that changes the whole picture.

Good or bad, everything we do is our best choice at that moment.
