=Literary Activity.=--Herbart's literary activity at Koenigsberg was great. He worked out his psychological system, and wrote also on philosophy, history, and pedagogy. But his greatest works in the latter field are his "A B C der Anschauung,"[159] and his "Allgemeine Paedagogik,"[160] both of which appeared while he was still at Goettingen.[161] In 1833, after twenty-four years in Koenigsberg, he returned to Goettingen, where his lifework was completed in 1841. Upon his retirement from Koenigsberg, the practice school was closed. Ten years later, a pupil of Herbart, Karl Volkmar Stoy, established the practice school at Jena, of which mention has already been made. Two schools of Herbartians exist in Germany, the Stoy school, which attempts to follow Herbart very closely, and the Ziller school, which is freer in its interpretation of him. The chief exponent of the latter is Professor Wilhelm Rein of Jena, the place which is at present the center of Herbartian activity. In America this movement is under the direction of the National Herbart Society. =His Pedagogical Work.=--Aside from the educational movements organized by Herbart and his followers, the credit is due to him of being the _first to elevate pedagogy to the dignity of a science_. Professor Rein says, "Herbart has rendered an undisputed service in that he has elevated pedagogics to the rank of a science. No one has ever repented of having become familiar with Herbart's teachings, for, in any case, he has thereby added richly to his own attainments. The development of our people will be fortunate if the education of the youth shall be intrusted more and more to those who stand and work upon the lines laid down by Comenius, Pestalozzi, Herbart. "The pedagogic thinking of Herbart has indeed borne rich fruit in Germany. Other peoples, also, have been blessed by his teachings. Thus Herbart, whose span of life did not reach to the middle of this century, lives in the present. He created the basis of a science of education, which furnishes a safe starting point for all pedagogical theories, and which bears in itself the most fruitful germs for future development."[162] =Modern Herbartians= have carried forward that development far beyond its original outline. The terms "many-sided interest," "apperception," "concentration," "culture-epochs," "the formal steps of instruction," "correlation," and "harmonious development," are phrases that have become common in educational literature. The limits of this volume do not permit a discussion of these subjects. Indeed, many of them belong more properly to the disciples of Herbart, rather than to Herbart himself.[163] Herbart's ideal was that education should aim to produce well-rounded men, fit for all the duties of life; men well developed physically, intellectually, morally, and spiritually. He himself was not one-sided, being an enthusiastic teacher as well as psychologist and philosopher. FOOTNOTES:
