We may remark here, that the exercise is not limited in its application to the young. For if an adult were first told, that the squalid beggar before him, though once respectable and rich, had made himself wretched by a course of idleness and dissipation, and were then asked, "What does that teach you?" he would instantly perceive the lesson, and would be stimulated to apply it. When, in like manner, the farmer is told that his neighbour has ruined himself by over-cropping his ground; or the iron master, that the use of the hot-blast has doubled the profits of his rival; a similar question would at once lead to the legitimate conclusion, and most likely to the proper conduct.
In all these examples, the operation of mind which we have endeavoured to describe, is so exceedingly simple, that it is perhaps difficult to decide how much is the work of Nature, and how much belongs to the exercise here recommended. This at once proves its efficiency, as an imitation of her process, in following her in the path which she has here pointed out; and it at the same time recommends itself as strictly accordant with observation and experience. The teacher then, in order to render the knowledge he communicates useful, has only to do regularly and by system, that which, under the direction of Nature, every intelligent and enquiring mind in its best moments does for itself. Wherever a useful truth has been communicated in the school or family, or a moral act or precept has been read or announced, the question by the parent or the teacher, "What does that teach you?" will lead the pupil to reflection, not only on its nature, but on its use; and the ability to do so, as we shall afterwards see, may be acquired by almost any individual with ease. Regular training in this way, leads directly to habits of reflection and observation, which are of themselves of great value; but which, when found acting in connection with the desire and ability to turn every truth observed into a practical channel, become doubly estimable, and a public blessing. The pupil therefore ought early to be trained of himself to supplement the question, "What does this teach me?" or, "What can I learn from this?" to every circumstance or truth to which his attention is called; because the ability to answer it forms the chief, if not the only correct measure of a well educated person. In proof of this it is only necessary to remark, that as it is not the man who has accumulated the greatest amount of anatomical and surgical knowledge, but he who can make the best use of it, that is really the best surgeon; so it is not the man who has acquired the largest portion of knowledge, but he who can make the best use of the largest portion, that is the best scholar. Hence it is, that all the exercises in a child's education should have in view the practical use of what he learns, and of what he is to continue through life to learn, as the great end to which all his learning should be subservient.
The moral advantages likely to result from the general adoption of this mode of teaching useful knowledge are exceedingly cheering, and the only surprise is, that it has been so long overlooked. That the principle, though not directly applied to the purposes of education, was well known, and frequently practised by our forefathers, appears obvious from many of their valuable writings. One beautiful example of its application is familiar to thousands, though not always perceived, in the illustration given of the Lord's prayer towards the close of the Assembly's Larger and Shorter Catechisms. The study of the lessons there drawn from the truths stated or implied in that prayer, will afford a better idea of the value of this mode of teaching, than perhaps any farther explanation we could give, and to these therefore we refer the reader.
Before closing these general observations upon the value and necessity of this method of training the young to the practical use of knowledge, there is a circumstance which should not be omitted, as it tends to double all the advantages of the exercise, both to the teacher and the pupil. It will be found in general, especially in morals, that every practical lesson that is drawn from a truth or passage, actually embodies two,—both of which are equally legitimate and connected with the subject. There is always a negative lesson implied, when the positive lesson is expressed; and there is in like manner a positive implied, whenever it is the negative that is expressed. As for example, when the child, from the history of Cain and Abel, draws the negative lesson that he should not hate his brother; the opposite of that lesson is equally binding in the positive form, that he should love his brother. And when, from the history of Job, the positive lesson is drawn that we ought to be patient; the negative of that lesson becomes equally binding, and the child may, by the very same fact, be taught and enjoined not to be fretful, discontented, or impatient, during sickness or trouble. Of this method of multiplying the practical uses of knowledge, we have a most appropriate example in the Assembly's Larger and Shorter Catechisms, where the illustrations given of the decalogue are conducted upon this important principle, and in a similar way.
CHAP. VIII.
On the Imitation of Nature in Teaching the Use of Knowledge
by means of the Animal or Common Sense.
A large portion of what has been advanced in the foregoing chapter, has reference to the practical application of all kinds of knowledge, whether by the Animal or Moral sense; and we shall here offer a few additional remarks on the teaching of those branches which are more immediately connected with the former.
When a person is sent to learn an art or trade, such as a carpenter, he is not sent to hear lectures, or to get merely an abstract knowledge of the several truths connected with it; but he is sent to practise the little knowledge that he is able of himself to pick up. His is a practical learning; ninety-nine parts in every hundred being employed in the practice, for one that is employed in acquiring the abstract principles of his occupation. When, on the contrary, a child is sent to school, to prepare him for this practical application of his knowledge, the former proportions are generally reversed, and ninety-nine parts of his time and labour are taken up in attaining abstract knowledge, for one that is occupied in assisting him to reduce it to practice. Both modes of teaching the boy are obviously wrong. He would, when sent to it, learn his business in much less time by a previous acquaintance with its principles; and all these ought to have been furnished him as a part of his general knowledge while he attended the school. Such information, indeed, ought to have formed a large portion of his education;—and it will be a matter of surprise to every one who closely considers the subject, how soon and how easily the principles, even of so complicated a trade as a carpenter, may be acquired when they are taught in the right way, and at the proper time. A few of the simplest principles in mechanics practically learned,—a knowledge of the strength and adhesion of bodies,—of the nature of edge tools,—and the importance of accuracy and caution, might have been made familiar to him while attending his studies; and if carefully and constantly reduced to practice, these would have been of the greatest service to him when called to the work-shop.
