In the olden times, the diversity of groups was largely a geographical matter. There were many societies, but each, within its own territory, was comparatively homogeneous. But with the development of commerce, transportation, intercommunication, and emigration, countries like the United States are composed of a combination of different groups with different traditional customs. It is this situation which has, perhaps more than any other one cause, forced the demand for an educational institution which shall provide something like a homogeneous and balanced environment for the young.
John DeweyHistorically the great movements for human liberation have always been movements to change institutions and not to preserve them intact. It follows from what has been said that there have been movements to bring about a changed distribution of power to do - and power to think and to express thought is a power to do- so that there would be a more balanced, a more equal, even, and equitable system of human liberties.
