In the pedagogical as in certain other spheres freedom is not allowed to erupt, the power of the opposition is not allowed to put a word in edgewise: they want submissiveness. Only a formal and material training is being aimed at and only scholars come out of the menageries of the humanists, only "useful citizens" out of those of the realists, both of whom are indeed nothing but subservient people. Our good background of recalcitrancy [sic] gets strongly suppressed and with it the development of knowledge to free will. The result of school is then philistinism.
