Now in my previous paper I showed how a theoretic knowledge of good conduct had better not be given to children. By exposition of holy laws they are not nourished, but enfeebled. What they need is right habits, not an understanding of them: to become good persons rather than to acquire a critical acquaintance with goodness. What moral function then remains for the schools? To furnish knowledge of morality has been proved dangerous. For teachers to turn away from imparting knowledge and devote their scanty time to fashioning character is to abandon work which they alone are fitted to perform. Yet to let them send forth boys and girls alert in mind and loose in character is something which no community will long endure. Until one has clearly faced these alternative perplexities he is in no condition to advise about grafting morality into a school curriculum; for until then he will be pretty sure to be misled by the popular notion of morality as a thing apart, demanding separate study, a topic like geography or English literature. But the morality nutritious for school-children is nothing of this kind. No additional hour need be provided for its teaching. In teaching anything, we teach it. A false antithesis was therefore set up just now when we suggested that a teacher's business was to impart knowledge rather than to fashion character. He cannot do the one without the other. Let him be altogether true to his scientific aims and refuse to accommodate them to anything else; he will be all the better teacher of morality. Carlyle tells of a carpenter who broke all the ten commandments with every stroke of his hammer. A scholar breaks or keeps them with every lesson learned. So conditioned on morality is the process of knowing, so inwrought is it in the very structure of the school, that a school might well be called an ethical instrument and its daily sessions hours for the manufacture of character. Only the species of character manufactured will largely depend on the teacher's acquaintance with the instrument he is using. To increase that acquaintance and give greater deftness in the use of so exquisite an instrument is the object of this paper. Once mastered, the tools of his own trade will be more prized by the earnest teacher than any additional handbook of ethics. It will be easiest to point out the kind of moral instruction a school is fitted to give, if we distinguish with somewhat exaggerated sharpness its several lines of activity. A school is primarily a place of learning; it is unavoidably a social unit, and it is incidentally a dependent fellowship. No one of these aspects is ever absent from it. Each affords its own opportunity for moral training. The combination of them gives a school its power. Yet each is so detachable that it may well become the subject of independent study.
