The training of the elementary school teacher tends to be dogmatic. True it is that vigilant individuality and passionate love for his exquisitely spiritual calling impel the school teacher to an untiring criticism of his methods, of his actual teaching, and of the life of the school which he directs and promotes. But nevertheless in consequence of those very studies by which he has prepared himself to be an elementary instructor, he is led to look upon that learning which constitutes his mental equipment and the foundation of all his future teaching, as something quite finished, rounded out, enclosed in definite formulas, rules, and laws, all of which have been ascertained once for all and are no longer susceptible of ulterior revision. He looks upon this learning not as a developing organism, but as something definitely moulded and stereotyped. From this the conclusion is drawn that a certain kind of knowledge may serve as a corner stone for the whole school edifice. Since his discipline and his teaching consist mainly of elements which because of their abstractness miss the renovating flow of spiritual life, the teacher slowly but surely ends by shutting himself up in a certain number of ideas, which are final as far as he is concerned. They are never corrected or transformed; in their mechanical fixity they cease to live; and the mind which cherishes and preserves them loses its natural tendency to doubt. Yet what is doubt but dissatisfaction with what is known and with the manner of knowing, and a spur to further inquiry, to better and fuller learning, to self scrutiny, to an examination of one's own sentiments, one's own character, and an inducement to broadmindedness, to a welcoming receptiveness of all the suggestions and all the teachings which life at all moments generously showers on us?
