While it appears to be a law of Nature, that there can be no accumulation of knowledge without the act of reiteration, yet there are other principles which she brings into operation in connection with it, by which the amount of the various branches of knowledge received is greatly increased, and the knowledge itself more easily comprehended, and more permanently retained upon the memory.

The first of these principles, which we have before alluded to and described, is that of "individuation;" that principle by which an infant or child is induced to concentrate the powers of its mind upon a new object, and that to the exclusion for the time of every other, till it has become acquainted with it.

In a former chapter we found, that as long as a child remains solely under the guidance of Nature, it will not allow its attention to be distracted by different unknown objects at the same time; but whenever it selects one for examination, it invariably for the time abandons the consideration of every other. The consequence of this is, that infants, with all their physical and mental imbecility, acquire more real knowledge under the tuition of Nature in one year, than children who are double their age usually gain by the imperfect and unnatural exercises of unreformed schools in three or four. The cause of this is easily detected, and may be illustrated by the analogy of any one of the senses. The eye, for example, like the mind, must not only see the object, but it must look upon it—examine it—before the child can either become acquainted with it at the time, or remember it afterwards. But if unknown objects are made rapidly to flit past the eye of the child, so that this cannot be done before there is time to fix the attention upon any of them, the labour of the exhibitor is not only lost, but the sight of the child is impaired;—the eye itself is injured, and is less able, for some time afterwards, to look steadily upon any other object, even when that object is stationary. Such is the injury and the confusion created in the mind of a child when it is hurried forward from object to object, or from truth to truth, before the mind has had leisure to lay hold of them, or to concentrate its powers upon the ideas they suggest. The labour of the teacher in that case is not only lost, and the child harassed and irritated, but the powers of the mind, instead of being brightened and strengthened, are bewildered and mystified, and must therefore be weakened in a corresponding degree.

The method to be adopted therefore for the imitation of Nature in the working of this principle, will consist in bringing forward, for the consideration of the child, every new letter, or word, or truth, or object, by itself. When presented separately and alone, there is no distraction of mind—no confusion of ideas; the child is allowed to consider it well before learning it, so that he will know something of its form or its nature, and will remember it again when it is either presented to his notice alone, or when it is grouped with others. His idea of the object or truth may be indistinct and faint at first, but it is correct so far as it goes; and the ideas which he retains concerning it, are obviously much more extensive, than if the mind at its first presentation had been disturbed or bewildered by the addition of something else.

His idea of the object or the truth, after being repeatedly considered, may still be very inadequate, but it will now be distinct; and it is the want of this precision in the pupil's mind that so frequently deceives teachers, and confuses and obstructs the future advance of the scholars. When a child hears, or reads a passage, the teacher, who understands it himself, too often takes it for granted that the child as he proceeds is reiterating the ideas as well as himself, and is of course master of the subject. But this is not always the case; and wherever the child has not succeeded in doing so, all that follows in that lesson is usually to the child the cause of confusion and difficulty. He finds himself at a stand; and however far he may in these circumstances be dragged forward, he has not advanced a step, and he must at some future period,—and the sooner the better,—return again to the same point, and proceed anew under serious disadvantages.

In almost every stage of a child's education, the neglect of this principle is seriously and painfully felt. It is the cause of acute mental suffering to well affected and zealous pupils; and it is the chief origin of all the heartlessness, and idleness, and apathy, which are found to pervade and regulate the conduct of those that are less active. A careful appliance of this principle of individuation, therefore, is always of importance in education; but it ought never to be forgotten, that it is more peculiarly valuable and necessary at the commencement, than at any other period of a child's progress in learning. We shall advert to a few of the methods by which it may be applied in ordinary school education, in contrast with some instances in which it is neglected.

In teaching the alphabet to children, the principle of individuation is indispensable; and its neglect has been productive of serious and permanent mischief. A child of good capacity, by a proper attention to this principle, will, with pleasure and ease, learn the names and forms of the letters, with the labour of only a few hours;[15] while, by neglecting the principle, the same child would, after years of irritation and weariness, be still found ignorant of its alphabet. The overlooking of the principle at this period has done an immense deal of injury to the cause of education. It has, at the very starting post in the race of improvement, quenched and destroyed all the real, as well as the imaginary delights of learning and knowledge. It has given the tyro such an erroneous but overwhelming impression of the difficulties and miseries which he must endure in his future advance, that the disgust then created has often so interwoven itself with his every feeling, that education has during life appeared to him the natural and necessary enemy to every kind of enjoyment.

It used to be common, and the practice may still we believe be found lingering among some of the lovers of antiquity, to make a child commence at the letter A, and proceed along the alphabet without stopping till he arrived at Z; and this lesson not unfrequently included both the alphabets of capitals and small letters. Now the cruelty of such an exercise with a child will at once be apparent, if we shall only change its form. If a teacher were to read over to an infant twice a-day a whole page or paragraph without stopping of Cæsar or Cicero in Latin, and demand that on hearing it he shall learn it, we could at once judge of the difficulty, and the feelings of a volatile mind chained to the constant and daily repetition of such a task; and if this exercise were termed its "education," we can easily conceive the amount of affection that the child would learn to cherish towards it. Now this is really no exaggerated illustration of the matter in hand, for in both cases the principle of individuation, so carefully guarded and enforced by Nature, is equally outraged; and it is only where, by some means or other, a remedy for the evil accidentally occurs, that the result in the case of the alphabet, is not exactly the same as it would have been in the case of the classics above supposed. The writer once saw in a Sunday school, where the children were taught twice each Sabbath, a class in which some of the children had attended for upwards of two years, and were still in their alphabet; and if the same mode had been pursued, there is little doubt that they would have been in it yet.

The remedy for this evil is obvious. Instead of confounding the eye and the mind of the child, by rapidly parading twenty-six, or fifty-four forms, continuously and without intermission before the pupil, the letters ought to be presented to the child singly, or at most by two at a time; and these two should be rendered familiar, both in name and in form, before another character is introduced. When a few of the more conspicuous letters have become familiar, another is to be brought forward, and the child may be made to amuse himself, by picking out from a page of a book, all the letters he has learned, naming them, and if necessary describing them to a companion or a sub-monitor as they occur. Or he may be set down by himself, with a waste leaf from an old book, or pamphlet, or newspaper, to prick with a pin the new letter or letters last taught him; or, as an introduction to his writing, he may be made to score them gently with ink from a fine tipped pen. In these exercises, and all others which are in their nature similar, the principle of individuation is acknowledged and acted upon; and therefore it is, that a child will, by their means, acquire an acquaintance with the letters in an exceedingly short time, and, which is of still greater importance, without irritation or trouble. These methods may sometimes be rendered yet more effective, by the teacher applying the catechetical exercise to this comparatively dry and rather forbidding part of a child's education. It proceeds upon the principle of describing each letter, and attaching its name to the description, such as "round o," "spectacle g," "top dotted i," &c. as in the "Classified Alphabet." The teacher has thus an opportunity of exercising the child's imagination, as well as its memory, and making a monotonous, and comparatively unintellectual exercise, one of considerable variety and amusement.

In teaching the alphabet to adults, whose minds are capable of appreciating and applying the principle of analysis, the "Classified Alphabet" should invariably be used. By this means their memory, in endeavouring to recall the form and name of any particular letter, instead of having to search through the whole twenty-six, has never to think of more than the four or five which compose its class,—a circumstance which makes the alphabet much more easily acquired by the adult than by a child. But even here, the principle of individuation must not be lost sight of; each letter in the class must be separately learned, and each class must be familiar, before another is taught.
