There are countries where it would be considered a truism that a teacher in order to exercise his profession intelligently should know something about the chief authorities in it. Here, however, I suppose such an assertion will seem paradoxical; but there is a good deal to be said in defence of it. De Quincey has pointed out that a man who takes up any pursuit without knowing what advances others have made in it works at a great disadvantage. He does not apply his strength in the right direction, he troubles himself about small matters and neglects great, he falls into errors that have long since been exploded. An educator is, I think, liable to these dangers if he brings to his task no knowledge but that which he learnt for the tripos, and no skill but that which he acquired in the cricket ground or on the river. If his pupils are placed entirely in his hands, his work is one of great difficulty, with heavy penalties attached to all blundering in it; though here, as in the case of the ignorant doctor and the careless architect, the penalties, unfortunately, are paid by his victims. If (as more commonly happens) he has simply to give a class prescribed instruction, his smaller scope of action limits proportionally the mischief that may ensue; but even then it is obviously desirable that his teaching should be as good as possible, and he is not likely to employ the best methods if he invents as he goes along, or simply falls back on his remembrance of how he was taught himself, perhaps in very different circumstances. I venture to think, therefore, that practical men in education, as in most other things, may derive benefit from the knowledge of what has already been said and done by the leading men engaged in it, both past and present. All study of this kind, however, is very much impeded by want of books. “Good books are in German,” says Professor Seeley. I have found that on the history of Education, not only _good_ books but _all_ books are in German or some other foreign language.[1] I have, therefore, thought it worth while to publish a few such imperfect sketches as these, with which the reader can hardly be less satisfied than the author. They may, however, prove useful till they give place to a better book.
