Mankind likes to think in terms of extreme opposites.

Give the pupils something to do, not something to learn; and the doing is of such a nature as to demand thinking; learning naturally results.

Such words as "society" and "community" are likely to be misleading, for they have a tendency to make us think there is a single thing corresponding to the single word.

To have an idea of a thing is not just to get certain sensations from it. It is to be able to respond to the thing in view of its place in an inclusive scheme of action; it is to foresee the drift and probable consequence of the action of the thing upon us and of our action upon it.

There is not, in fact, any such thing as the direct influence of one human being on another apart from use of the physical environment as an intermediary. A smile, a frown, a rebuke, a word of warning or encouragement, all involve some physical change. Otherwise, the attitude of one would not get over to alter the attitude of another.

Inference is always an invasion of the unknown, a leap from the known.

To the being of fully alive, the future is not ominous but a promise; it surrounds the present like a halo.
