Throughout this Course for teachers, we have steadily laid emphasis on the need in the pupil for the cultivation of self-control as a basis for any satisfactory building of character. Scarcely less have we insisted that the same trait of character is essential in a successful teacher. Our survey of the blunders of disciplinarians leads to the conclusion that by far the larger part committed by school teachers can be traced back to an inexcusable lack of this central virtue of self-control. The passionate, selfish teacher can not see the pupil’s point of view. The measureless transformations of the adolescent period throw a vast majority of people out of sympathy with the adolescent and still more with those of younger years. The system of school discipline advocated in this Course for teachers, frankly rests on coöperation with the pupil, initiative being taken by the teacher in working out disciplinary problems in frank, wholehearted adjustment to pupil needs and characteristics. No teacher can adopt the policy represented by this principle without attaining, in a measure, and further developing his own self-control. Our experience and observation, our fresh survey of all the facts while compiling the data presented in these volumes, have deepened immeasurably the conviction that the teacher who seeks the level of the life of the children whom he wishes to govern, assisting them, aiding them, guiding them according to the dictates of their natures rather than contrariwise, will cure himself of one of his own worst vices, namely, anarchy in mood, temper and judgment; and will develop in its place the basic element of a noble character, self-control. By presenting, as a final word, the contrast between these two teachers, we hope to heighten the impressions that have repeatedly been made as the reader has followed the narratives and discussions contained in the preceding pages. Remember that the two men here described worked under the same circumstances, during the same two years, with the same pupils, in the same building; that each had the benefit of consultation with the other, that both were well received in public and had many friends among the business men and in the homes of the city. The advantage in physical organization lay with him who failed. The essential difference between the two is found in the inner, basic attitude of each toward his pupils.
