We believe that education is one of the principal causes of discontent of late years manifesting itself among the laboring classes. (The Senate Committee on Education, 1888)The book is freely downloadable from here.
Every teacher should realize he is a social servant set apart for the maintenance of the proper social order and the securing of the right social growth. (John Dewey, 1897)
[schools should be factories]... "in which raw products, children, are to be shaped and formed into finished products...manufactured like nails, and the specifications for manufacturing will come from government and industry." (Elwood Cubberly—the future Dean of Education at Stanford, 1905)
In our dreams...people yield themselves with perfect docility to our molding hands... (Rockefeller Education Board—which funded the creation of numerous public schools, 1906).
