Clearer evidences of this reflexion on to nature of the characteristics of his own life appear when a child begins to speculate about mechanical processes, which he invariably conceives of after the analogy of his own actions. This was illustrated in dealing with children’s questions. We see it still more clearly manifested in some of their ideas. One of the most curious instances of this that I have met with is seen in early theorisings about the cause of wind. One of the children examined by Mr. Kratz said the tree was to make the wind blow. A pupil of mine distinctly recalls that when a child he accounted for the wind at night by the swaying of two large elms in front of the house and not far from the windows of his bedroom. This reversing of the real order of cause and effect looks silly, until we remember that the child necessarily looks at movement in the light of his own actions. He moves things, _e.g._, the water, by his moving limbs; we set the air in motion by a moving fan; it seems, therefore, natural to him that the wind-movements should be caused by the pressure of some moving thing; and there is the tree actually seen to be moving. So far I have spoken for the most part of children’s ideas about near and accessible objects. Their notions of what is distant and inaccessible are, as remarked, wont to be formed on the model of the first. Here, however, their knowledge of things will be largely dependent on others’ information, so that the naïve impulse of childish intelligence has, as best it may, to work under the limitations of an imperfectly understood language.
