A year after the death of Stoy, 1886, Dr. Wilhelm Rein was called to the chair of pedagogy at Jena. He had studied both with Stoy and Ziller, and had added to this an extensive experience as a teacher and as principal of a normal school. His lectures on pedagogy, both theoretical and practical, in connection with his seminary for discussion and his practice school for application of theory, furnish an admirable introduction to the most progressive educational ideas of Germany.

The Herbart school stands for certain progressive ideas which, while not exactly new, have, however, received such a new infusion of life-giving blood that the vague formulae of theorists have been changed into the definite, mandatory requirements and suggestions of real teachers. The fact that a pedagogical truth has been vaguely or even clearly stated a dozen times by prominent writers, is no reason for supposing that it has ever had any vital influence upon educators. The history of education shows conclusively that important educational ideas can be written about and talked about for centuries without finding their way to any great extent into school rooms. What we now need in education is definite and well-grounded theories and plans, backed up by honest and practical execution.

The Herbartians have patiently submitted themselves to thorough-going tests in both theory and practice. After years of experiment and discussion, they come forward with certain propositions of reform which are designed to infuse new life and meaning into educational labors.

The first proposition is to make the foundation of education immovable by resting it upon growth in moral character, as the purpose which serious teachers must put first. The selection of studies and the organization of the school course follow this guiding principle.

The second is permanent, many-sided interest. The life-giving power which springs from the awakening of the best interests in the two great realms of real knowledge should be felt by every teacher. Though not entirely new, this idea is better than new, because its deeper meaning is clearly brought out, and it is rationally provided for by the selection of interesting materials and by marking out an appropriate method of treatment. All knowledge must be infused with feelings of interest, if it is to reach the heart and work its influence upon character by giving impulse to the will.

Thirdly, the idea of organized unity, or concentration, in the mental stores gathered by children, in all their knowledge and experience, is a thought of such vital meaning in the effort to establish unity of character, that, when a teacher once realizes its import, his effort is toned up to great undertakings.

Fourthly, the culture epochs give a suggestive bird's-eye view of the historical meaning of education, and of the rich materials of history and literature for supplying suitable mental food to children. They help to realize the ideas of interest, concentration, and apperception.

Apperception is the practical key to the most important problems of education, because it compels us to keep a sympathetic eye upon the child in his moods, mental states, and changing phases of growth; to build hourly upon the only foundation he has, his previous acquirements and habits.

Finally, the Herbartians have grappled seriously with that great and comprehensive problem the common school course. The obligation rests upon them to select the materials and to lay out a course of study which embodies all their leading principles in a form suited to children and to our school conditions.

Some of the principal books published in English bearing on Herbart are as follows:
