PREFACE 



IN 1924 the Corporation of Yale University did 

 me the honor of asking me to deliver the first 

 series of Dwight H. Terry Lectures. I have to thank 

 the Corporation for this fine opportunity and for the 

 many kindnesses shown to me during my visit to 

 Yale. 



I was led by the widespread discussion of Evolu- 

 tion to devote the three lectures to different aspects 

 of evolutionist inquiry. They deal with the Making 

 of Worlds, the Evolution of Organisms, and the 

 Emergence of Man. My object was to show that evo- 

 lutionist description is not inconsistent with religious 

 interpretation. Indeed the evolutionist view of Na- 

 ture and of Man makes for enrichment and encour- 

 agement. The lectures are not systematic expositions 

 of evolution in the domain of things, the realm of 

 organisms, and the kingdom of man: they are in- 

 tended rather to show how evolutionary science may 

 illumine the religious outlook. The lectures are pub- 

 lished almost as they were spoken, except that the 

 second has been much expanded. I am greatly in- 

 debted to Professor J. H. McGregor of Columbia 

 University for his permission to use a photograph of 

 three of his remarkable restorations.
