EDITOR'S PREFACE 



SO much emphasis has been placed upon the 

 biological factor in the writings of sociolo- 

 gists, that Professor Davies' book brings a 

 new element into the discussion of social 

 problems. How far does the .accumulated 

 knowledge and experience of the world modify 

 the individual and give him control over bio- 

 logical factors? The source of ability, mental 

 p^vver, and moral force, after all, appears as 

 the important element in society. The contri- 

 bution which this book makes is in the empha- 

 sis given to influences of social environment 

 upon the growth and personality of the indi- 

 vidual. War and war talk are the logical 

 outcome of the biological contest, but in real- 

 ity should be offset by an appreciation of the 

 psychological and spiritual elements of civiliza- 

 tion, which, when properly measured, are larger 

 factors than the biological forces so reverently 

 referred to by most
