ABSTRACT
Psychology as the discipline of interiority is grounded on the notion of psychological difference, which may be expressed as the notional difference between the concepts of "man" and "soul". The generic sense of "soul" may guide us into anthropology provided we take it from an ontological viewpoint, whereas the specific notion necessarily leads to psychology proper. In the psychological use, as constituting one pole of the psychological difference, "man" and "ego" are equivalent, synonymous, have exactly the same meaning. Hence, as "ego" means "a mode of perceiving, a style of thinking", this is the meaning of "man", when this concept is taken psychologically. The gross misunderstanding that chapter have pointed out above comes from an undialectical and unpsychological understanding of the psychological difference, which takes the constitutive terms of the difference as simple opposites, excluding one another, and also substantializes both terms as ontological entities.
