"Egocentrism in children clearly appears to be a simple continuation of solipsism in infants. Egocentrism, as we have seen, is not an intentional or even a conscious process. A child has no idea that he is egocentric. He believes everybody thinks the way he does, and this false universality is due simply to an absence of the sense of limits on his individuality. In this light, egocentrism and solipsism are quite comparable: both stem from the absence or the weakness of the sense of self."
