It would seem that the matter of population has something to do with the production of talent. Aggregations of population offer frequent contact of persons, division of labor, competition between individuals, a better coordination of society for cooperative results, neutralization of physical qualities, and the ascendancy of innovation over the conservative attitude. It is not the mere density of population which is the effective element. It is rather the dynamic density which is productive, that is, the manifestation of the common life and spirit. City life is specialized in structure and function, rendering men more interdependent and cooperative. Specialization means moral coalescence

The chateaux of France are very prolific in producing talent. They yielded 2 per cent. of all the talent of the period, seemingly out of proportion to their importance.

Why are certain of the cities and the chateaux more fertile than most cities and the country in producing the talented? We have a general reply in the statement as to the dynamic density of cities. A further analysis finds those communities are possessed of elements which the country does not have. Odin calls them "properties." They are the location of the political, administrative and judicial agencies of society; they are in possession of great wealth and talent; they are depositories of learning and the tools of information. The avenues which open upon talent and the tools and agencies by means of which the passage to it is to be made segregate themselves in cities and towns

As the result of his investigation into the distribution of men of science in the United States, Professor Cattell arrives at nearly the same conclusion. He writes:

'The main factors in producing scientific and other forms of intellectual performance seem to be density of population, institutions and social traditions and ideals. All these may be ultimately due to race, but, given the existing race, the scientific productivity of the nation can be increased in quantity, though not in quality, almost to the extent that we wish to increase it.'[4]

It is interesting to note that nearly all of the women of talent have been born in cities and chateaux. This means that women had to be born where the means of development were to be had, as they were not free to move about in society, as were men.

The economic factor has been an important one in offering the leisure which is necessary for the development of talent. Men who have to use their time and energy wholly in the support of themselves and families are deprived of the leisure which productivity and creativeness in work demands. Of the French men of letters 35 per cent. belonged to the wealthy or noble class, 42 per cent. to the middle class, and 23 per cent. to the working class. Odin was able to discover the economic environment of 619 men of talent. They were distributed by periods between the rich and poor as shown in the table on page 169.

Of one hundred foreign associates of the French Academy the membership of the wealthy, middle and working classes were 41, 52 and 7. A combination of two other of Candole's tables yields for those classes in per cents 35, 42 and 23. In ancient and medieval times practically all of the talented came from the wealthy class. On the whole, but about one eleventh of the men of talent had to fight with economic adversity. But when we remember that the wealthy class formed but a small portion of the population in each period, probably not more than one fourth, this means that as compared with members of the working class individuals of the wealthy class had forty or fifty times as good a chance of rising to a position of eminence. The contrast is so sharp that Odin is led to exclaim, "Genius is in things, not in man."
