On the connections between philosophy and politicizing education:
“Kant’s philosophic successors, Fichte and Hegel, elaborated the idea that the chief function of the state is educational; that in particular the regeneration of Germany is to be accomplished by an education carried on in the interests of the state, and that the private individual is of necessity an egoistic, irrational being, enslaved to his appetites and to circumstances unless he submits voluntarily to the educative discipline of state institutions and laws. In this spirit, Germany was the first country to undertake a public, universal, and compulsory system of education extending from the primary school through the university, and to submit to jealous state regulation and supervision all private educational enterprises.”
