CHAP. VIII.

On Nature's Methods of Teaching her Pupils to make use of their Knowledge.

We come now to another operation of Nature with the young, to which she appears to attach more importance than she does to any of her previous educational processes, and to which she obviously intends that a more than ordinary attention should be paid on our parts. This is the training of her pupils to make use of their knowledge, and to apply the information they possess to guide them in the common affairs of life. This is obviously the great end which she has all along had in view; and to which the cultivation of the mind, and the acquisition of knowledge are merely preparatives. We shall first direct attention to a few of the indications of this principle as they actually appear in ordinary life; and then we shall endeavour to point out some of the laws by which she appears to regulate them.

In the early periods of infancy we can plainly distinguish between certain actions which depend upon instinct, and which are performed by the infant perfectly and at once, without experience, and without teaching;—and others of which the infant at first appears to be incapable, but which it gradually acquires by experience, or more correctly, which it learns by an application of the knowledge which it is daily realizing. Among the former, or instinctive class, we may rank the acts of sucking, swallowing, and crying, which are purely acts of instinct; while among the numerous class belonging to the latter, we include all those actions which are progressively improved, and which are really the result of experience, derived from the application of their acquired knowledge. As an example of these, we may instance the acts of winking with the eyelids on the approach of an object to the eye; the avoiding of a blow; the rejection of what is bitter or unpalatable; the efforts made to possess that which has been found pleasant; and the shunning of those acts for which it has been reproved or punished. All these, and thousands of similar acts, are really the result of a direct application of previous knowledge, and which, without the possession of that knowledge, never are, nor could be performed.

Mankind in infancy being, in the intention of Nature, placed under the care of tender and intelligent parents are not provided with many instinctive faculties. Their physical welfare is at first left altogether to the care of the nurse; but, from a very early period of consciousness, they intellectually become the pupils of Nature. Almost all their actions are the results of experience;—of knowledge acquired, and knowledge applied. Their attainments at the beginning are no doubt few;—but, from the first, they are well marked, and go on with increasing rapidity. The acquisition of knowledge by them, and especially the application of it, are evident to the most cursory observer. For example, we see a child cling to its keeper, and refuse to go to a stranger;—we see it when hungry stretch out its arms, and cry to get to its nurse;—and when it has fallen in its efforts to walk, it will not for some time attempt it again. These, and many more which will occur to the reader, are the results of Nature's teaching;—her suggestions to her pupil for the right application of its knowledge. The child has been taught from experience that it is safe and comfortable with its keeper, and it applies this knowledge by refusing to leave her. It has learned how, and by whom, its hunger is to be satisfied; and it applies this knowledge by seeking to be with its nurse. It has learned by experience, that the attempt to walk is dangerous; and it applies that knowledge by avoiding the danger. Here the child is wholly as yet in the hands of Nature; and it is quite evident, that her design in first enabling the pupil to acquire those portions of knowledge, was, that she might induce him to apply them for his safety and comfort. No doubt the mental powers of the child were cultivated and disciplined by the acquisition of the knowledge, and still more by its application; but this disciplining of the mind, and accumulation of knowledge, were evidently a secondary object, and not the primary one. Health and cheerfulness are gained by tilling the ground; yet the ground is not tilled for the purpose of securing health and cheerfulness. It is for the produce of the harvest. So, in like manner, the cultivation of the child's mind, and the reception of the seeds of knowledge, are merely means employed for a further end,—the harvest of comfort and usefulness to be afterwards reaped. From all this we are directly led to the conclusion, that it is the intention of Nature, that all the knowledge acquired should be put to use; and therefore, that nothing should be taught the young, in the first place at least, except that which is really useful; while the proper use of all that they learn should be diligently pointed out.

It may appear to some, that this truth is so plain and obvious, as to require no further illustration or enforcement.—We sincerely wish that it were so. But long experience justifies us in being sceptical on the point. And as the establishment of this principle, and a thorough knowledge of its working, are perhaps of more value than any other truth in the whole range of educational science, we shall offer a few remarks on its validity and importance, before proceeding to examine the means by which Nature carries it into operation.

That knowledge, when once acquired, is intended by Nature to be put to use, is proved negatively by the well known fact, that almost all our mental acquirements, when not used, are soon lost. They gradually fade from the mind, and are at last blotted from the memory. Hence the disappearance in after life of all the academical and collegiate acquirements of those youths who move in a sphere where their use is not required; and of those portions of the early attainments of even professional men, which are not necessary for their particular pursuits. By the universal operation of this principle, Nature gives fair warning of the folly of useless learning; and plainly indicates, that whenever the benefits which she confers are not put to use as she designed, they will gradually, but most certainly, be withdrawn.

The same fact is also proved positively:—For we find, that the proper use of any portion of our knowledge, is invariably rewarded by its becoming still more familiar. The student who puts a principle in chemistry to the test of experiment, will understand it better, remember it longer, and be able to apply it to useful purposes, much more readily than his companion who merely reflects upon it. And of two individuals, who by a lecture have been taught the duty and the delights of mercy, that one will learn it best, and remember it longest, who, immediately on hearing it, is prompted to relieve a fellow creature from distress, or to save a family from ruin.

This principle of making every thing conduce to the promotion of practical good, seems to pervade all the works of God; and there is no department in Nature, mineral, vegetable, or animal, that does not afford proofs of its existence. Every thing that the Almighty has formed is practically useful; and is arranged in such a manner as to give the clearest indications, that it was designed to be turned to some useful purpose by man. The annual and diurnal motions of the earth in its orbit; the obliquity of its axis; the inequality of its surface, and the disposition and disruption of its strata, all shew the most consummate wisdom, and are severally a call to intelligent man to turn them to use. On these, and on every other department of Nature's works, there is written in legible characters, that it is the use of knowledge, and not the possession of it merely, that is recommended. This she teaches by every operation of her hand, both directly, and by analogy. For could we suppose that the vegetable creation were capable of receiving knowledge, we might conclude from various facts, that this principle was not confined to the animal kingdom alone, but that it regulated the operations of all organic existences. The living vegetable has at least the appearance of acting under its influence; for, as if it knew that light was necessary for its health and growth, it invariably turns towards the light;—as if it knew that certain kinds of decayed matter were better fitted for its nourishment than others, it pushes out new fibrous roots in the direction of the spot where they are to be found;—and even when isolated on a rock, or a wall, at a distance from sufficient soil and moisture, it husbands its scanty means, and sends down from its elevation an extra root to the ground, to collect additional nourishment where it is to be had.

In every department of animal life, also, the principle appears to exist, and exhibits itself in the conduct of all free agents, from the insect to the elephant. The dog that has been kindly treated in a particular house, seldom fails to visit it again; and when he is violently driven from another, the same principle indisposes him to return. It is upon record, that a surgeon who had bandaged the broken leg of a dog, was afterwards visited by his patient, who brought another, requiring a similar operation. The horse, in like manner, is proverbially sagacious in the application of his knowledge. Mismanagement in a groom in one instance, may create a "vice," which may lessen his value during life. This "vice," which is confirmed by practice, is nothing more than the repeated application of his knowledge. Such a "vice," accordingly, is best cured by avoiding the circumstances which originally gave rise to it, till it dies from his memory. Many other instances of a similar kind in the lower animals will readily occur to the reader, all of which lead directly to the conclusion, that, even in the brute creation, Nature not only prompts them to collect information from what happens around them, and to act in correspondence to its indications; but that, in fact, all the knowledge they receive, or are capable of acquiring above instinct, is retained or lost, exactly in proportion as it is, or is not, put to use.
