There's all the difference in the world between having something to say, and having to say something.

Every teacher should realize the dignity of his calling.

A society with too few independent thinkers is vulnerable to control by disturbed and opportunistic leaders. A society which wants to create and maintain a free and democratic social system must create responsible independence of thought among its young.

Selection aims not only at simplifying but at weeding out what is undesirable.

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.

While every social arrangement is educative in effect, the educative effect first becomes an important part of the purpose of the association in connection with the association of the older with the younger.

There is no such thing as educational value in the abstract. The notion that some subjects and methods and that acquaintance with certain facts and truths possess educational value in and of themselves is the reason why traditional education reduced the material of education so largely to a diet of predigested materials.
