§ 9. The second division unfolds the subject of the physical, intellectual and practical culture of the human race, and constitutes the main part of all books on Pedagogy. Here arises the greatest difficulty as to the limitations, partly because of the undefined nature of the ideas, partly because of the degree of amplification which the details demand. Here is the field of the widest possible differences. If e.g. one studies out the conception of the school with reference to the qualitative specialities which one may consider, it is evident that he can extend his remarks indefinitely; he may speak thus of technological schools of all kinds, to teach mining, navigation, war, art, &c. § 10. The third division distinguishes between the different standpoints which are possible in the working out of the conception of Education in its special elements, and which therefore produce different systems of Education wherein the general and the particular are individualized in a special manner. In every system the general tendencies of the idea of education, and the difference between the physical, intellectual and practical culture of man, must be formally recognized, and will appear. The How is decided by the standpoint which reduces that formalism to a special system. Thus it becomes possible to discover the essential contents of the history of Pedagogics from its idea, since this can furnish not an indefinite but a certain number of Pedagogic systems. ——The lower standpoint merges always into the higher, and in so doing first attains its full meaning, e.g.: Education for the sake of the nation is set aside for higher standpoints, i.g., that of Christianity; but we must not suppose that the national phase of Education was counted as nought from the Christian standpoint. Rather it itself had outgrown the limits which, though suitable enough for its early stage, could no longer contain its true idea. This is sure to be the case in the fact that the national individualities become indestructible by being incorporated into Christianity——a fact that contradicts the abstract seizing of such relations.—— § 11. The last system must be that of the present, and since this is certainly on one side the result of all the past, while on the other seized in its possibilities it is determined by the Future, the business of Pedagogics cannot pause till it reaches its ideal of the general and special determinations, so that looked at in this way the Science of Pedagogics at its end returns to its beginning. The first and second divisions already contain the idea of the system necessary for the Present. FIRST PART. The General Idea of Education. § 12. The idea of Pedagogics in general must distinguish, (1) The nature of Education in general; (2) Its form; (3) Its limits. I. _The Nature of Education._
