Mankind likes to think in terms of extreme opposites.

Personality must be educated, and personality cannot be educated by confining its operations to technical and specialized things, or to the less important relationships of life. Full education comes only when there is a responsible share on the part of each person, in proportion to capacity, in shaping the aims and policies of the social groups to which he belongs.

We have three approaches at our disposal: the observation of nature, reflection, and experimentation. Observation serves to assemble the data, reflection to synthesise them and experimentation to test the results of the synthesis. The observation of nature must be assiduous, just as reflection must be profound, and experimentation accurate. These three approaches are rarely found together, which explains why creative geniuses are so rare.

A large part of the art of instruction lies in making the difficulty of new problems large enough to challenge thought, and small enough so that, in addition to the confusion naturally attending the novel elements, there shall be luminous familiar spots from which helpful suggestions may spring.

What nutrition and reproduction are to physiological life, education is to social life.

We are a people of many races, many faiths, creeds, and religions. I do not think that the men who made the Constitution forbade the establishment of a State church because they were opposed to religion. They knew that the introduction of religious differences into American life would undermine the democratic foundations of this country. What holds for adults holds even more for children, sensitive and conscious of differences. I certainly hope that the Board of Education will think very, very seriously before it introduces this division and antagonism in our public schools.

Thinking and feeling that have to do with action in association with others is as much a social mode of behavior as is the most overt cooperative or hostile act.
