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.
If now, on the basis of the preceding definition, we seek to define the significance of personality in social and public life, it appears that personality is the basis upon which all social institutions, movements, and conditions, in short all the phenomena of social life, rest. The people of our time are no more, as in the Golden Age, inarticulate masses. They are a totality of more or less active personalities connected by common interests, in part by racial origin, and by a certain similarity of fundamental psychic traits. A people is a kind of collective personality possessing particular ethnic and psychological characteristics, animated by common political aspirations and political traditions. The progress of peoples, their civilization, and their culture naturally are determined by the advancement of the personalities which compose them. Since the emancipation of mankind from a condition of subjection, the life of peoples and of societies has rested upon the active participation of each member of society in the common welfare which represents the aim of all. The personality, considered as a psychic self-determining individual, asserts itself the more energetically in the general march of historical events, the farther a people is removed from the condition of subjection in which the rights of personality are denied.
In every field of activity, the more advanced personality "blazes a new trail." The passive personality, born in subjection, is disposed merely to imitate and to repeat. The sheer existence of modern states depends less on the crude physical force and its personified agencies, than on the moral cohesion of the personalities who constitute the nation.
Since the beginning of time, it is only the moral values that have endured. Force can support the state only temporarily. When a nation disregards the moral forces and seeks its salvation in the rude clash of arms, it bears within itself the seeds of its own destruction. No army in the world is strong enough to maintain a state, the moral basis of which is shaken, for the strength of the army rests upon its morale.
The importance of personality in the historic life of peoples is manifest in periods when social conditions accelerate the movement of social life. Personality, like every other force, reaches its maximum when it encounters resistance, in conflict and in rivalry—when it fights—hence its great value in friendly rivalry of nations in industry and culture, and especially in periods of natural calamities or of enemies from without. Since the fruits of individual development contribute to the common fund of social values, it is clear that societies and peoples which, other things being equal, possess the most advanced and active personalities contribute most to the enrichment of civilization. It does not seem necessary to demonstrate that the pacific competition of nations and their success depends on the development of the personalities which compose them. A nation weak in the development of individualities, of social units which compose it, could not defend itself against the exploitation of nations composed of personalities with a superior development.
D. BIOLOGICAL AND SOCIAL HEREDITY
1. Nature and Nurture[75]
We have seen that the scientific position in regard to the transmissibility of modifications should be one of active scepticism, that there seems to be no convincing evidence in support of the affirmative position, and that there is strong presumption in favor of the negative.
A modification is a definite change in the individual body, due to some change in "nurture." There is no secure evidence that any such individual gain or loss can be transmitted as such, or in any representative degree. How does this affect our estimate of the value of "nurture"? How should the sceptical or negative answer, which we believe to be the scientific one, affect our practice in regard to education, physical culture, amelioration of function, improvement of environment, and so on? Let us give a practical point to what we have already said.
a) Every inheritance requires an appropriate nurture if it is to realize itself in development. Nurture supplies the liberating stimuli necessary for the full expression of the inheritance. A man's character as well as his physique is a function of "nature" and of "nurture." In the language of the old parable of the talents, what is given must be traded with. A boy may be truly enough a chip of the old block, but how far he shows himself such depends on "nurture." The conditions of nurture determine whether the expression of the inheritance is to be full or partial. It need hardly be said that the strength of an (inherited) individuality may be such that it expresses itself almost in the face of inappropriate nurture. History abounds in instances. As Goethe said, "Man is always achieving the impossible." Corot was the son of a successful milliner and prosperous tradesman, and he was thirty before he left the draper's shop to study nature.
