In my opinion personality is not merely a unifying and directing principle which controls thought and action, but one which, at the same time, defines the relation of individuals to their fellows. The concept of personality includes, in addition to inner unity and co-ordination of the impulses, a definite attitude directed toward the outer world which is determined by the manner in which the individual organizes his external stimulations. In this definition the objective aspect of personality is emphasized as over against the subjective. We should not in psychological matters be satisfied with subjective definitions. The mental life is not only a sum of subjective experiences but manifests itself invariably also in a definite series of objective expressions. These objective expressions are the contributions which the personality makes to its external social environment. More than that, only these objective expressions of personality are accessible to external observation and they alone have objective value. According to Ribot, the real personality is an organism which is represented at its highest in the brain. The brain embraces all our past and the possibilities of our future. The individual character with all its active and passive peculiarities, with all its antipathies, genius, talents, stupidities, virtues, and vices, its inertia and its energy is predetermined in the brain. Personality, from the objective point of view, is the psychic individual with all his original characters, an individual in free association with his social _milieu_. Neither innate mental ability, nor creative energy, nor what we call will, in and of themselves, constitutes personality. Nothing less than the totality of psychical manifestations, all these including idiosyncrasies which distinguish one man from another and determine his positive individuality, may be said to characterize, from the objective point of view, the human personality. The intellectual horizon of persons on different cultural levels varies, but no one, for that reason (because of intellectual inferiority), loses the right to recognition as a person, provided that he maintains, over against his environment, his integrity as an individual and remains a self-determining person. It is the loss of this self-determined individuality alone that renders man completely impersonal. When individual spontaneity is feebly manifested, we speak of an ill-defined or a "passive" personality. Personality is, in short, from the objective point of view, a self-determining individual with a unique nature and a definite status in the social world around him.
