PREFACE 



This Inquiry has been prosecuted In 

 close collaboration with Dr. M. R. Gab- 

 bert, Professor of Philosophy In the Uni- 

 versity of Pittsburgh, to whom I here 

 make grateful acknowledgment for guid- 

 ance in that wide borderland where scien- 

 tific and philosophical methods overlap. 

 I am also indebted to Dean Frederick J. E. 

 Woodbridge of Columbia University for 

 helpful criticism. The argument upon 

 which this work is based has been pub- 

 lished In more condensed form In a paper 

 entitled "Biological Determinism and Hu- 

 man Freedom," International Journal of 

 Ethics, vol. 37, 1926. With the kind per- 

 mission of the editors of the Journal, parts 

 of this paper are here Incorporated. 



The present work is directed, not to 

 the philosophical aspects of the subject, 

 but to a more practical end. When hu- 

 man life — all of it — is evaluated biologi- 

 cally, where do we come out of the mazes 

 of human origins and human destiny, of 

 the determining factors of human conduct, 

 of personal control and responsibility, of 

 social betterment — or do we come out at 

 all?
