In this passage from Émile, Rousseau advises that children practice the art of drawing in order to learn how to recognize the size and shape of objects. He justifies his advice by arguing that drawing or copying the shape of objects enhances our grasp of the laws of perspective. The art of drawing is not merely a playful game, it is also an activity with an important cognitive function. In the Critique, too, the notion of drawing appears in the context of cognitive theory. For instance, when I perceive a house, Kant tells us at B 162, it is as if I draw its shape. Especially in his theory of schematism, references to constructive acts like drawing abound. How are we to understand these references? In this chapter I will argue that these constructive acts may be understood as acts involving the body, acts in which we somehow recreate the shape of external objects by moving parts of our bodies, as when we draw an image of them. I do not claim that this idea, in exactly this form, is found in Émile. At a more general level, however, I hold it to represent yet another example of a perspective shared by Rousseau and Kant, a perspective emphasizing that embodied acts and practices have a significant cognitive function.
