“ Hence, we may suppose, arises the consciousness of a permanent self and not-self. It should be observed that self-consciousness varies according to the intellectual development, and the term “personality” is usually connected only with the self-consciousness of an advanced type, not, for example, with that of an animal. Even among human beings there is considerable difference. The most elementary form of human self-consciousness includes in the self not only the soul but also the body, while to the developed self-consciousness the physical self is part of the external or objective world. ”
