In our investigations into the nature and working of this principle, as detailed in a former chapter, we found several causes which gave rise to certain uniform effects, which, for the purpose of imitation or avoidance, may be classed under the following heads:—We found,
1. That wherever the principle of grouping acted with effect, it had always been preceded by the principle of individuation.
2. That wherever the principle of individuation was made to interfere, the effect intended by the principle of association was in the same degree obstructed or destroyed.
3. That whenever ideas or objects, whether known or unknown, were presented to a child in greater number than the mind could receive or reiterate them, it silently dropped the surplus;—but if these were forced upon the mind, all the mischiefs arising from the interference of the two hostile principles immediately took place.
4. That children, in grouping under the tuition of Nature, received and retained the impressions of objects presented to their notice, in a natural and regular order;—forming in their minds a continuous moving scene, where motion formed a part of it; and that this movement of the objects, actually was a portion of the grouping.
These being the facts connected with this portion of Nature's educational process, the object of the teacher should be to endeavour to imitate her in all these circumstances; carefully avoiding what she has shewn to be inoperative and hurtful, and copying as closely as possible all those that tend to forward the objects of instruction.
The first thing then to be attended to by the teacher, is, that in every attempt to communicate knowledge to a child by the grouping of objects, he takes care that the principle of individuation has preceded it;—that is, that the various ideas or objects to be grouped, be individually familiar to the pupil. In communicating a story, therefore, or an anecdote, or in teaching a child to read, care must be taken that the objects or individual truths, the words, or the letters, be previously taught by themselves, before he be called upon to group them in masses, whether greater or smaller. If this be neglected, an important law of Nature is violated, and the lesson to this extent will be ineffective, or worse. But if, on the contrary, this rule be attended to, the pupil, when he comes to these objects in the act of grouping, is prepared for the process; he meets with nothing that he is not familiar with; he has nothing to learn, and has only to allow the objects to take their proper places, as when he looked into the room, and grouped its contents as before supposed. All this being perfectly natural, is accomplished without effort, and with ease and pleasure.—This precaution on the part of the teacher, will at once remove many of the difficulties and embarrassments which have hitherto pressed so heavily upon the pupil in almost every stage of his advance, but more especially in the early stages of his learning to read.[17]
As an illustration of our meaning, we may notice here, that a child who knows what is meant by "sheep," and "the keeping of sheep," of "tilling the ground," and "making an offering to God," &c. is prepared to hear or to read an abridgement of the story of Cain and Abel. We say an abridgement or first step, for reasons which shall afterwards be explained. Without a previous knowledge of these several elements of which this story is compounded, he could neither have listened to it with pleasure, nor read it with any degree of profit; but as soon as these are individually familiar, the grouping,—the knowledge of the whole story,—is a matter of ease, and generally of delight. As the story advances, it causes a constant and regular series of groupings on the mind by the imagination, which are at once exquisitely pleasing and permanent. The child, as in a living and moving picture, imagines a man laboriously digging the ground, and another man in a distant field placidly engaged in attending to the wants and the safety of a flock of sheep. He imagines the former heaping an altar with fruits and without fire; and the latter killing a lamb, laying its parts on an altar, while a stream of fire descends from the skies and consumes it. His imagination goes on with increasing interest to picture the quarrel-scene in the field; and he in effect sees the blow given by the club of Cain, that destroyed the life of his brother. All this living and moving scene will be remembered in groups; and these groups will be more or less closely linked together, and will be imagined more or less distinctly as a whole, in proportion to the mental advancement of the particular child.
The next thing to be attended to in communicating knowledge to a child by grouping, is, that no strange for unknown object or idea be introduced among those which he is called upon to group; because in that case, the operation will be materially interfered with, and either marred or destroyed. The completeness of this operation in the hands of Nature, depends in a great measure, as we have seen, upon the perfect composure and self-possession of the mind during the process. If there be no interruption,—no element of distraction introduced into the exercise,—all the circumstances, as they arise in the gradual developement of the story, are comprehended and grouped. The living and moving picture is permanently fixed upon the memory, so that it may be recalled and reviewed at any future time. But if, on the contrary, the placidity of the mind be interrupted,—if some strange and unknown object be introduced, whose agency is really necessary for connecting the several parts of the story,—the very attempt of the child to become individually acquainted with it, throws the whole process into confusion; and he has either to drop the contemplation of this necessary part of the machinery, or to lose the benefit of all that is detailed during the time he is engaged with it. In either case the end is not gained; and the great design aimed at by the teacher,—the communication of the knowledge connected with the narrative,—is more or less frustrated. Like the landscape pictured on the placid bosom of the lake, the formation and contemplation of his own undisturbed imaginings are delightful to the child; but the introduction of an unknown object, like the dropping of a stone in the former case, produces confusion and distortion, which are always unpleasant and painful.
One general reason why the introduction of unknown objects into these groupings of the child is so pernicious, may also be here adverted to. It arises from the circumstance, that no person, whether young or old, can form, even in his imagination, the idea of an entirely new thing. This is commonly illustrated by the well known fact, that it is impossible to conceive of a new sense;—but it is equally applicable to the conception of a new object. Adults can no doubt conceive and picture on their imaginations, objects and scenes which they never saw;—but this mental act is not the imagining of an entirely new thing. All such scenes or things are compounded of objects, or parts of objects, which they have seen, and with which they are familiar. They can readily picture to themselves a centaur or a cerberus, a mermaid or a dragon,—creatures which have no existence, and which never did exist; but a little reflection will shew, that nothing which the mind conceives of these supposed animals is really new, but is merely a new combination of elements, or parts of other animals, already familiar. Children accordingly can easily conceive the idea of a giant or a dwarf, a woman without a head, or a man with two, because the elements of which these anomalies are compounded are individually familiar to them;—but were they told of a person sitting in a howdah, or being conveyed in a palanquin, without having these objects previously explained or described to them, the mind would either be drawn from the story to find out what these meant, and thus they would lose it; or they would, on the spur of the moment, substitute in their minds something else which perhaps had no likeness to them, and which would lead them into serious error. For example, they might suppose that the one was a house, and the other a ship;—a supposition which would distort the whole narrative, and would render many of its parts inconsistent and incomprehensible.
