Let us return then to the point from which we set out, namely: that one important difference between the teacher and other operatives arises from the difference in the objects on which they operate. The one operates upon matter, the other upon mind. The one attains perfection in his art by a process which in the other would produce an ignoramus, a bungler, a narrow-minded, conceited charlatan. Hence the necessity on the part of those who would excel in the profession of teachers, of endeavoring continually to enlarge the bounds of their knowledge. Hence the error of those who think that to teach anything well it is necessary to know only that one thing. That young woman who undertakes to teach a primary school, or even an infant class, has mistaken her calling if she supposes that because she has to teach only the alphabet or the "table card," she has therefore no need to know many other things. There are some things which every teacher needs. Every teacher needs a cultivated taste, a disciplined intellect, and that enlargement of views which results only from enlarged knowledge.
We all know how much we are ourselves benefited by associating habitually with persons of superior abilities. So it is in a still higher degree with children. There is something contagious in the fire of intellect. The human mind, as well as the human heart, has a wonderful power of assimilation. Every judicious parent will say: Let not my child be consigned to the care of an ill-informed, dull, spiritless teacher. Let it be his happy lot, if possible, to be under one who has some higher ambition than merely to go through a certain prescribed routine of duties and lessons; one whose face beams with intelligence and whose lips drop knowledge; one who can cultivate in him the disposition to inquire, by his own readiness and ability to answer childish inquiries; who can lead the inquiries of a child into proper channels, and train him to a correct mode of thinking by being himself familiar with the true logical process, by having himself a cultivated understanding. Such a teacher finds a pleasure in his task. He finds that he is not only teaching his pupils to read and to spell, to write and to cipher, but he is acquiring an ascendancy over them. He is exerting upon them a moral and intellectual power. He is leaving, upon a material far more precious than any coined in the Mint, the deep and inerasible impress of his own character.
