  But the broader, realist personalism does posit, in the classical and scholastic tradition, the essential difference between man and all other objects on man’s ability to reason (and its corollary of language), which differentiates a person from the whole world of objective entities. Since it is precisely his intellectual and spiritual nature that makes subjectivity possible, one can say that in the subjectivity of the human person is also something objective. Yet these personalists insist on the clear separation between non-personal beings and this subjectivity of the person which is derivative of his rational nature in a broader or higher sense.  Regardless of how, more precisely, animals are to be understood, the person differs from even the most advanced among them by a specific kind of inner self, an inner life, which, ideally, revolves around his pursuit of truth and goodness, and generates person-specific theoretical and moral questions and concerns.
