The full significance of the Gary plan can scarcely be understood unless it is seen against this background. “It is impossible,” says Professor Dewey, “to exaggerate the amount of mental and moral training secured by our forefathers in the course of the ordinary pursuits of life. They were engaged in subduing a new country. Industry was at a premium, and instead of being of a routine nature pioneer conditions required initiative, ingenuity, and pluck.... Production had not yet been concentrated in factories in congested centers, but was distributed through villages.... The occupations of daily life engaged the imagination and enforced knowledge of natural materials and processes.... Children had the discipline that came from sharing in useful activities.... Under such conditions the schools could hardly have done better than devote themselves to books.... But conditions changed, and school materials and methods did not change to keep pace. Population shifted to urban centers. Production became a mass affair carried on in big factories, instead of a household affair.... Industry was no longer a local or neighborhood concern. Manufacturing was split up into a very great variety of separate processes through the economies incident upon extreme division of labor.... The machine worker, unlike the older hand worker, is following blindly the intelligence of others instead of his own knowledge of materials, tools and processes.... Children have lost the moral and practical discipline that once came from sharing in the round of home duties. For a large number there is little alternative, especially in large cities, between irksome child labor and demoralizing child idleness.”
