IOO AMERICAN MEN OF LETTERS [ IO o 



Nevertheless, in spite of all the evidence of the great 

 influence of environment, Ward's attractive theory that 

 nature is a negligible quantity could not be accepted. 

 In the first place, it was argued that not all persons 

 whose environments are good succeed in rising beyond 

 mediocrity. Again, it was noted that many persons do 

 achieve success when environmental conditions are ex- 

 tremely unfavorable. Finally, it was pointed out that a

 education adequate to develop latent ability, and a social 

 environment furnishing incentive to the naturally en- 

 dowed and amply educated to turn their attention to

 have also been important in so far as they facilitate the

 be held by scientific men. The fact is readily explicable, 

 however. Apparently both men were carried away by 

 their enthusiasm for their theses. Each was desirous of 

 convincing the world that human welfare could be fur- 

 thered by improving the factor which he emphasized. 

 In his eagerness to support his major proposition he as-
