CHAPTER XIV 
THE RACIAL INFLUENCE OF INDUSTRIAL 
DEVELOPMENT. 
“A few good and healthy men, rather than a multitude of diseased 
rogues; and a little real milk and wine rather than much chalk and 
petroleum; but the gist of the whole business is, that the men, and 
their property, must both be produced together—not one to the loss of 
the other. Property must not be created in lands desolate by exile of 
their people,—nor multiplied and depraved humanity, in lands barren 
of bread.” —Ruskin, The Queen of the Air. 
It is obvious that many of the most potent of the factors 
which influence the inherited qualities of man are the result of the 
great industrial development which has taken place during the 
past century. To give an adequate account of the complex and 
indirect ways in which the growth of modern industry has affected 
the development of the race is at present an impossible task. 
Even most of the simpler problems cannot be solved with the 
data at present available, and where the immediate result of 
certain forces seems fairly obvious there are commonly secondary 
and more indirect effects to be considered which stand in various 
relations with, and sometimes in direct antagonism to, the 
primary ones. 
The magnitude and rapidity of the changes which industrial 
development has effected in the institutions of mankind tend to 
divert attention from the more obscure biological problems with 
which they are associated. It will perhaps be useful to formulate 
some of these problems, although we may not be able to contrib- 
ute much to their solution. 
Among the more immediate effects of industrial development 
are (1) the increase of population in many countries which has 
been rendered possible by the creation of additional occupations 
and the expansion of trade; (2) the growth and multiplication of
