A period of high civilization is one in which thoughts fly freely from mind to mind, from one country to another-yes, from the past into the present.

The mind never need stop growing. Indeed, one of the few experiences which never pall is the experience of watching one's own mind and how it produces new interests, responds to new stimuli, and develops new thoughts, apparently without effort and almost independently of one's own conscious control.

The best school in the world will scarcely save a boy who hates the school and the purpose it serves and the society that created it.

I believe that much of the maladjustment in our societies is caused, not by malevolence and corruption, but simply by ignorance.

If you do not actually like boys and girls, or young men and young women, give up teaching.

Many of the snarly bad-tempered teachers whom we remember with hatred were really nice people soured by years of anxiety and penny-pinching.

The chief aim of education is to show you, after you make a livelihood, how to enjoy living; and you can live longest and best and most rewardingly by attaining and preserving the happiness of learning.
