Toys are to a child what a grown-up is represented by his power of speech, his pen, pencil and typewriter, his motor car, his bicycle, his power of acting, cooking, and carpentering. From his earliest years a healthy child has an immense curiosity about the outside world. He is not aware of himself as a person separate from his own body. He has, as it were, to think with his body. He uses, therefore, those parts of his body with which he is already familiar—that is to say, his mouth and tongue to begin with, then his hands and feet, and any other part of his body that he can move—with which to investigate new aspects of life.
