In performances of this kind, a superior understanding is not by any means exhibited, but a stronger memory and faculty of association. These associations are not, however, of a logical sort, but are habits acquired through training, and they may even retard the development of the intellect if they become numerous. For they may obstruct the formation, at an early period, of independent ideas, merely on account of the time they claim. Often, too, these artificial associations are almost useless for the development of the intellect. They are too special. On this ground I am compelled to censure the extravagancies, that are wide-spread especially in Germany, of the Froebel methods of occupying young children. The _logic of the child_ naturally operates at the beginning with much more extensive, and therefore less intensive, notions than those of adults, with notions which the adult no longer forms. But the child does not, on that account, proceed illogically, although he does proceed awkwardly. Some further examples may illustrate. The adult does not ordinarily try whether a door that he has just bolted is fast; but the one-year-old child tests carefully the edge of the door he has shut, to see whether it is really closed, because he does not understand the effect of lock and bolt. For even in the eighteenth month he goes back and forth with a key, to the writing-desk, with the evident purpose of opening it. But at twelve months, when he tries whether it is fast, he does not think of the key at all, and does not yet possess a single word. An adult, before watering flowers with a watering-pot, will look to see whether there is water in it. The child of a year and a half, who has seen how watering is done, finds special pleasure in going from flower to flower, even with an empty watering-pot, and making the motions of pouring upon each one separately, as if water would really come out. For him the notion "watering-pot" is identical with the notion "filled watering-pot," because at first he was acquainted with the latter only.
