By a consideration of French regions by departments, provinces, and principal sections, as to their yield of talent, the physical environment was found to have had no perceptible influence. The mountain-situated Geneva and the lowland Paris produced alike prolifically talented men. The valley of the Seine and that of the Loire competed for hegemony in fecundity. The facts contradicted the highland theory, the lowland theory, the coast theory, and every other theory of the dominance of physical environment. To get at the influence of the ethnological factor the Gaulic, Cimbrian, Iberian, Ligurian and Belgic elements of the population were examined as to their fecundity in talent. Odin confesses to being unable to discover "the least connection between races and fecundity in men of letters." Attention was paid likewise to races speaking other than French language. Again there was a conflict of facts. Inside of France ethnological elements exerted "no appreciable influence upon literary productivity." In Belgium and Lorraine, where the German language dominated, it was found that French literature mastered the situation, thus indicating that a common language does not necessitate a common literature. The conclusion ethnologically is that races possess an equality in yielding talent. The religious factor was found to have been more influential formerly in bringing to light talent than at the close of the five-hundred-year period. From 1300 to 1700 the church furnished on the average 37.8 per cent. of all literary talent. Its fecundity dropped to 29 in the period from 1700 to 1750. Between 1750 and 1825 it produced but 6.5 of the talent. As Galton has shown, eminent men were killed or driven out during the period of religious persecution in Spain, France and Italy. The celibacy of the clergy which gave undisturbed leisure may have been an element in making the church productive in the earlier years. On the other hand, the quieting effect of family life of the protestant ministry seems to have had a propitious influence in later times, as there appeared a relative increase among protestant clergy of talent, while the output among the catholic clergy continued to decline. In this investigation the local environment appeared to have the most influence in the production of talent. Odin gave witness to having a suspicion that somewhere there was a neglected factor. The facts connected talent with the cities in an overwhelming manner. The statement that genius is the product of the rural regions seems to have had no legs to stand on. The majority of the talented were born in the cities and practically all of them were connected with city life.
