"The organization of reality occurs, as we shall see, to the extent that the self is freed from itself by finding itself and so assigns itself a place as a thing among things, an event among events.The transition from chaos to cosmos, which we shall study in the perception and representation of the world in the first two years, is brought about through an elimination of egocentrism comparable to that which we have described on the plane of the child's reflective thought and logic."--P. xiii.
