The field of biological research in which there is to-day 

 the greatest activity is unquestionably ^genetics. In any 

 new branch of science little attention is given, in the 

 first flush of investigation, to the logical concepts and 

 philosophical principles which underlie it. This lack 

 of philosophical poise is now becoming rather generally 

 apparent in genetic research. The present book is a 

 contribution to the methodology of genetics, in a philo- 

 sophical sense. It attempts first to examine carefully and 

 then to appraise the value of the more important current 

 methods of attacking the problems of heredity and breed- 

 ing, includine; the statistical or biometrical method, Men- 

 delism, etc. The book should, on the one hand, interest 

 every professional student of biology in any of its 

 branches, who is at all concerned with the question of the 

 philosophical foundation of his science. On the other 

 hand, the publicist and man of affairs who is concerned to 

 know what significance is to be attached to the eugenics 

 movement should find in this book some aid in orienting 

 himself.
