The three papers on differences between sexes, races, and individuals serve as an introduction into the problem of differentiating the aspects of behavior which are in original nature from those that are acquired through social experience. Are the apparent differences between men and women, white and colored, John and James, those which arise from differences in the germ plasm or from differences in education and in cultural contacts? The selections must not be taken as giving the final word upon the subject. At best they represent merely the conclusions reached by three investigators. Attempts to arrive at positive differences in favor either of original nature or of education are frequently made in the interest of preconceived opinion. The problem, as far as science is concerned, is to discover what limitations original nature places upon response to social copies, and the ways in which the inborn potentialities find expression or repression in differing types of social environment.

b) Human nature and social life.—Original nature is represented in human responses in so far as they are determined by the innate structure of the individual organism. The materials assembled under this head treat of inborn reactions as influenced, modified, and reconstructed by the structure of the social organization.

The actual reorganization of human nature takes place in response to the folkways and mores, the traditions and conventions, of the group. So potentially fitted for social life is the natural man, however, so manifold are the expressions that the plastic original tendencies may take, that instinct is replaced by habit, precedent, personal taboo, and good form. This remade structure of human nature, this objective mind, as Hegel called it, is fixed and transmitted in the folkways and mores, social ritual, i.e., Sittlichkeit, to use the German word, and convention.

c) Personality and the social self.—The selections upon "Personality and the Social Self" bring together and compare the different definitions of the term. These definitions fall under three heads:

(1) The organism as personality: This is a biological statement, satisfactory as a definition only as preparatory to further analysis.

(2) Personality as a complex: Personality defined in terms of the unity of mental life is a conception that has grown up in the recent "individual psychology," so called. Personality includes, in this case, not only the memories of the individual and his stream of consciousness, but also the characteristic organization of mental complexes and trends which may be thought of as a supercomplex. The phenomena of double and multiple personalities occur when this unity becomes disorganized. Disorganization in releasing groups of complexes from control may even permit the formation of independent organizations. Morton Prince's book The Dissociation of a Personality is a classic case study of multiple personality. The selections upon "The Natural Person versus the Social and Conventional Person" and "The Divided Self and the Moral Consciousness" indicate the more usual and less extreme conflicts of opposing sentiments and interests within the organization of personality.

(3) Personality as the rôle of the individual in the group: The word personality is derived from the Latin persona, a mask used by actors. The etymology of the term suggests that its meaning is to be found in the rôle of the individual in the social group. By usage, personality carries the implication of the social expression of behavior. Personality may then be defined as the sum and organization of those traits which determine the rôle of the individual in the group. The following is a classification of the characteristics of the person which affect his social status and efficiency:

(a) physical traits, as physique, physiognomy, etc.;
(b) temperament;
(c) character;
(d) social expression, as by facial expression, gesture, manner,
speech, writing, etc.;
(e) prestige, as by birth, past success, status, etc.;
(f) the individual's conception of his rôle.

The significance of these traits consists in the way in which they enter into the rôle of the individual in his social milieu. Chief among these may be considered the individual's conception of the part which he plays among his fellows. Cooley's discriminating description of "the looking-glass self" offers a picture of the process by which the person conceives himself in terms of the attitudes of others toward him.

The reflected or looking-glass self seems to have three principal elements: the imagination of our appearance to the other person; the imagination of his judgment of that appearance; and some sort of self-feeling, such as pride or mortification. The comparison with a looking-glass self hardly suggests the second element, the imagined judgment, which is quite essential. The thing that moves us to pride or shame is not the mere mechanical reflection of ourselves, but an imputed sentiment, the imagined effect of this reflection upon another's mind. This is evident from the fact that the character and weight of that other, in whose mind we see ourselves, makes all the difference with our feeling.[56]
