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.
