And first of all, _Religion and Morals_ are clearly pointed out by Nature as a branch of education peculiarly necessary for the young. On this we shall not here again enlarge, but shall merely refer the reader to some of our previous pages, where it has been made sufficiently clear.[30] Next in importance as a branch of education plainly indicated by Nature, we ought to rank _the principles of Natural Philosophy_. We say next _in importance_, not _in time_; because they are evidently not to be taught to the child in this order, although it will be found in experience that these principles may be communicated by successive "steps" much sooner than is generally thought.[31] Nature begins early; and so should we. The very infant becomes practically a natural philosopher, and continues to act regularly upon the truths or principles which experience enables him to detect. He soon learns that flame burns, that clothes keep his body warm, that stumbling will cause a fall, and that the support of a chair or stool will prevent it. As he grows up he learns the danger of handling sharp knives, hot irons, and burning coals; he learns to detect some of the effects of the mechanical powers, which he frequently applies, although he cannot explain them. This we perceive exemplified in his ingenious contrivances in cutting his sticks, wrenching with forks, hammering with stones, kicking with his toes, and afterwards more powerfully with his heels; in trundling his hoop, in sailing his mimic fleets by the force of his breath, and in adapting to the requisite moving powers his wind and water mills. He even learns to know something of the composition of forces, as we perceive by his contrivances in the flying of his kite, the shooting of his marbles, and the rebounding of his ball. Now, as these adaptations are never to be ranked under the class of instinctive actions, but have been in every case acquired by actual experience, it shews, that there is an outgoing of the mind in search of principles, and we think it is probable, that these principles are often, although perhaps but dimly perceived, from the various, and frequently successful contrivances of the child in difficulties, and in circumstances when he is desirous of procuring relief. This at all events shews us, that children are very early prepared, and capable of receiving instruction of this kind.
