This change in practice necessarily brought about a change in theory. The individualistic theory receded into the background. The state furnished not only the instrumentalities of public education but also its goal. When the actual practice was such that the school system, from the elementary grades through the university faculties, supplied the patriotic citizen and soldier and the future state official and administrator and furnished the means for military, industrial, and political defense and expansion, it was impossible for theory not to emphasize the aim of social efficiency. And with the immense importance attached to the nationalistic state, surrounded by other competing and more or less hostile states, it was equally impossible to interpret social efficiency in terms of a vague cosmopolitan humanitarianism. Since the maintenance of a particular national sovereignty required subordination of individuals to the superior interests of the state both in military defense and in struggles for international supremacy in commerce, social efficiency was understood to imply a like subordination. The educational process was taken to be one of disciplinary training rather than of personal development. Since, however, the ideal of culture as complete development of personality persisted, educational philosophy attempted a reconciliation of the two ideas. The reconciliation took the form of the conception of the "organic" character of the state. The individual in his isolation is nothing; only in and through an absorption of the aims and meaning of organized institutions does he attain true personality. What appears to be his subordination to political authority and the demand for sacrifice of himself to the commands of his superiors is in reality but making his own the objective reason manifested in the state--the only way in which he can become truly rational. The notion of development which we have seen to be characteristic of institutional idealism (as in the Hegelian philosophy) was just such a deliberate effort to combine the two ideas of complete realization of personality and thoroughgoing "disciplinary" subordination to existing institutions. The extent of the transformation of educational philosophy which occurred in Germany in the generation occupied by the struggle against Napoleon for national independence, may be gathered from Kant, who well expresses the earlier individual-cosmopolitan ideal. In his treatise on Pedagogics, consisting of lectures given in the later years of the eighteenth century, he defines education as the process by which man becomes man. Mankind begins its history submerged in nature--not as Man who is a creature of reason, while nature furnishes only instinct and appetite. Nature offers simply the germs which education is to develop and perfect. The peculiarity of truly human life is that man has to create himself by his own voluntary efforts; he has to make himself a truly moral, rational, and free being.
