THE DOGMA OF EVOLUTION 



itself must have developed some inherent and fatal 

 weakness. But these are mere post hoc, propter hoc 

 statements; if natural selection is a force which can 

 destroy but cannot create species and if the reasons 

 for this destruction are unknown, of what value is 

 the theory to mankind *? We can leave to the biolo- 

 gists the hope that some day they may enter the tem- 

 ple of life through the doors of evolution, but the 

 collapse of the theory of natural selection leaves the 

 philosophy of mechanistic materialism in a sorry 

 plight. Those who are trying to use its conclusions as 

 a guide to social polity and ethics will find them- 

 selves without any ground on which to stand if they 

 address themselves to a real study of biological evo- 

 lution.
