#13. Thinking Principles.#--In addition to the subject-matter, the teacher should know something of the laws of thought, and the best way to use knowledge as an agency in _forming_ these laws of thought. All these laws are scheduled in any elementary treatise on psychology, and the best method of using knowledge to train the soul is set forth in any good treatise on pedagogy. Thus to a knowledge of the subject-matter the teacher must add a knowledge of psychology and of pedagogy. Scholarship alone is not the test of a good teacher. #14.# If one reflects for a time upon his own methods of acquiring knowledge, he will begin to understand the operations of the human soul. When one reads that knowledge enters the soul only through the special senses, or that ideas may be recalled by memory, it is of the utmost importance that he should ask himself the question: What do these statements mean? An illustration will help to answer this question: I know that fire will burn my hand; the knowledge of this fact entered my consciousness through the sense of touch, and my memory recalls it. #15. Teaching Principles.#--When the laws of soul growth are fairly well understood, it is time to investigate the principles of pedagogy, the laws that govern the teacher in the act of using knowledge to occasion activity in the soul of a learner. For the laws of teaching rest upon the laws of the soul. We cannot know how to proceed in the teaching process until we know how the soul acts under given conditions. #16.# This act of teaching is a vastly significant one. It results in changing the viewpoint of the pupil's life. It should produce in his soul new knowledge, or power, or skill, or all of these combined. Consider well, teacher, what this means. How the child is taught determines in no small way how he will in the years to come regard his fellow-man, his country, his church, his own duty, and his loyalty to all that makes for progress in the life that is hid with Christ in God. #17.# There are certain educational principles of great value to the teacher. Consider what it means to adapt knowledge to the capacity of the learner, or what it means to secure interest in the learner, or what it means to proceed from the simple to the complex in teaching, and you will begin to understand something of the power of right activities in the recitation.
