Various Modes in which the Reserved Force reappears.
The force thus stored in the food and liberated within the system by the vital processes, finds scope for action in several different ways, prominent among which are, First, in the production of animal heat; Secondly, in muscular contractions and the motions of the limbs and members resulting from them; and Thirdly, in mental phenomena connected with the action of the brain and the nerves. This last branch of the subject is yet enveloped in great mystery; but the proof seems to be decisive that the nervous system of man comprises organs which are actively exercised in the performance of mental operations, and that in this exercise they consume important portions of the vital force. If, for example, a child is actually engaged at play, and we direct him to take a seat and sit still, he will find it very difficult to do so. The inward force will soon begin to struggle within him to find an issue. But if, while he is so sitting, we begin to relate to him some very surprising or exciting story, to occupy his mind, he will become motionless, and very likely remain so until the story is ended. It is supposed that in such cases the force is drawn off, so to speak, through the cerebral organs which it is employed in keeping in play, as the instruments by which the emotions and ideas which the story awakens in the mind are evolved. This part of the subject, as has already been remarked, is full of mystery; but the general fact that a portion of the force derived from the food is expended in actions of the brain and nervous system seems well established.
Indeed, the whole subject of the reception and the storing up of force from the sun by the processes of vegetable and animal life, and the subsequent liberation of it in the fulfillment of the various functions of the animal system, is full of difficulties and mysteries. It is only a very simple view of the general principle which is presented in these articles. In nature the operations are not simple at all. They are involved in endless complications which are yet only to a very limited extent unravelled. The general principle is, however, well established; and if understood, even as a general principle, by parents and teachers, it will greatly modify their action in dealing with the incessant restlessness and activity of the young. It will teach them, among other things, the following practical rules:
Practical Rules.
1. Never find fault with children for their incapacity to keep still. You may stop the supply of force, if you will, by refusing to give them food; but if you continue the supply, you must not complain of its manifesting itself in action. After giving your boy his breakfast, to find fault with him for being incessantly in motion when his system has absorbed it, is simply to find fault with him for being healthy and happy. To give children food and then to restrain the resulting activity, is conduct very analogous to that of the engineer who should lock the action of his engine, turn all the stop-cocks, and shut down the safety-valve, while he still went on all the time putting in coal under the boiler. The least that he could expect would be a great hissing and fizzling at all the joints of his machine; and it would be only by means of such a degree of looseness in the joints as would allow of the escape of the imprisoned force in this way that could prevent the repression ending in a frightful catastrophe.
Now, nine-tenths of the whispering and playing of children in school, and of the noise, the rudeness, and the petty mischief of children at home, is just this hissing and fizzling of an imprisoned power, and nothing more.
In a word, we must favor and promote, by every means in our power, the activity of children, not censure and repress it. We may endeavor to turn it aside from wrong channels—that is, to prevent its manifesting itself in ways injurious to them or annoying to others. We must not, however, attempt to divert it from these channels by damming it up, but by opening other channels that will draw it away in better directions.
2. In encouraging the activity of children, and in guiding the direction of it in their hours of play, we must not expect to make it available for useful results, other than that of promoting their own physical development and health. At least, we can do this only in a very limited degree. Almost all useful results require for their attainment a long continuance of efforts of the same kind—that is, expenditure of the vital force by the continued action of the same organs. Now, it is a principle of nature that while the organs of an animal system are in process of formation and growth, they can exercise their power only for a very brief period at a time without exhaustion. This necessitates on the part of all young animals incessant changes of action, or alternations of action and repose. A farmer of forty years of age, whose organs are well developed and mature, will chop wood all day without excessive fatigue. Then, when he comes home at night, he will sit for three hours in the evening upon the settle by his fireside, thinking—his mind occupied, perhaps, upon the details of the management of his farm, or upon his plans for the following day. The vital force thus expends itself for many successive hours through his muscles, and then, while his muscles are at rest, it finds its egress for several other hours through the brain. But in the child the mode of action must change every few minutes. He is made tired with five minutes' labor. He is satisfied with five minutes' rest. He will ride his rocking-horse, if alone, a short time, and then he comes to you to ask you to tell him a story. While listening to the story, his muscles are resting, and the force is spending its strength in working the mechanism of the brain. If you make your story too long, the brain, in turn, becomes fatigued, and he feels instinctively impelled to divert the vital force again into muscular action.
If, instead of being alone with his rocking-horse, he has company there, he will seem to continue his bodily effort a long time; but he does not really do so, for he stops continually, to talk with his companion, thus allowing his muscles to rest for a brief period, during which the vital force expends its strength in carrying on trains of thought and emotion through the brain.
He is not to be blamed for this seeming capriciousness. These frequent changes in the mode of action are a necessity, and this necessity evidently unfits him for any kind of monotonous or continued exertion—the only kind which, in ordinary cases, can be made conducive to any useful results.
