From the Unconscious to the Conscious 



imposed a particular rhythm on evolution, and have 

 favoured it, but they have not produced it. 



One might, strictly speaking, imagine evolution 

 proceeding without the intervention of selection or 

 adaptation ; but we cannot conceive it as proceeding by 

 them alone. 



This is the main conclusion to which we are irre- 

 sistibly led. 



Thus, classical naturalism, travelling by a very long 

 road, which it has vainly explored in every direction, 

 finds itself willingly or unwillingly, brought back to 

 seek the first cause which it has sought to avoid. Its 

 avowed inability to find the essential factors of evolution 

 allows of no more fresh starts on the same road. 



Fiske said that transformism had restored to the 

 world as much ' teleology ' 1 as it had taken away. 

 This is not happily expressed, for it implies the kind 

 of finality which would fix arbitrarily and in advance 

 the trend of evolution. 



But what is indubitable, and results clearly from a 

 thorough study of transformism, is the conclusion, that 

 evolutionary science cannot dispense with philosophy. 



1 Teleology the doctrine of adaptation to purpose.
