“A certain bygone philosophy-which certainly must have quite forgotten all about the real child-used to speak of the child's nature as a tabula rasa, or 'blank page,' upon which experience and training might write what they pleased. As a matter of fact, the child's nature at birth, like that of a calf or a chick, is pretty well scribbled over by the experience of its ancestors. It is far from being blank, for as soon as the little organism comes into the world, it begins to do certain things and do them with much zeal and determination, as every one knows who knows real children.”
