vi CREATIVE EVOLUTION 



Aristotelian Society of London, and the writer of several 

 studies of "Evolution Creatrice." 1 We asked him to be 

 kind enough to revise the proofs of our work. He has 

 done much more than revise them: they have come from 

 his hands with his personal mark in many places. We 

 cannot express all that the present work owes to him.
