A man can be prevented from breaking into other persons' houses by shutting him up, but shutting him up may not alter his disposition to commit burglary.

A narrow and moralistic view of morals is responsible for the failure to recognize that all the aims and values which are desirable in education are themselves moral. Discipline, natural development, culture, social efficiency, are moral traits - marks of a person who is a worthy member of that society which it is the business of education to further.

The real process of education should be the process of learning to think through the application of real problems.

Not only does social life demand teaching and learning for its own permanence, but the very process of living together educates. It enlarges and enlightens experience; it stimulates and enriches imagination; it creates responsibility for accuracy and vividness of statement and thought.

Nature is the mother and the habitat of man, even if sometimes a stepmother and an unfriendly home.

The educational process has no end beyond itself; it is its own end.

One might as well say he has sold when no one has bought as to say he has taught when no one has learned.
