FOREWORD 



be borrowed or coined, it should certainly express the new 

 principle that is implied in Lloyd Morgan's "emergence," in 

 Bergson's evolution creatrice, in Osborn's ''creative evolu- 

 tion," or in "creation by evolution," the title of the present 

 volume. 



This originative and creative principle of emergence, of 

 creative evolution, appears to be lacking in the lifeless 

 universe, even as revealed by the recent and most marvelous 

 discoveries in physics and chemistry, and in astronomy. 



Are not new physical elements compounded by the simpli- 

 fication or complication of older physical elements, to give 

 rise to new forms, but without the creation of new forces.'* 

 Is there not invariably in the physical and material world 

 antecedence and consequence, cause and effect? Are we not, 

 therefore, facing in the biological world a new recognition 

 of the order of Nature in the incessant creative, emergent 

 evolution of new forms, of new characteristics, of new 

 powers? Consequently the addition of new powers and new 

 properties seems peculiarly distinctive of life. 



Such questions, such problems, such contrasts as these 

 show that Darwinism, broad and manifold in its implica- 

 tions as the term has become, is only one aspect of the 

 whole evolution of life; there are many other and newer 

 aspects, unknown to Darwin and not implied in the term 

 "Darwinism," or even in the far more comprehensive term 

 "evolution." As Einstein follows Newton, so some great 

 philosopher of biology will follow Darwin, and the new 

 biology of the future will be even more inspiring than the 

 biology revealed by the many and able contributors to 

 the present volume.
