"/ liave no theory to propose to explain the origin of organic fit)iess 

 and human purpose other tluin the endowment of living beings ivith the 

 differential sensitiinly and reactivity tropisms, organic memory, trial 

 and error beliaviour, leading in higher animals to intelligence and purpose. 

 I do not doubt the reality of the niechanistic principles of physics and 

 chemistry and natural selection in the evolution of organis)ns with all 

 their adaptations. But with crude niechanism that finds everything the 

 result of accident ami cluince I liave no )nore sympathy than with tra)is- 

 cendental vitalism. Those who say there are no ends, values, purposes 

 in the living world may understand atoms, molecules, and even genes, 

 but they do not understand organisms. They see the elements of which 

 life is composed, but they fail to see the pattern and beauty of the entire 

 tapestry of life. " 



E. G. Conk I in 1944
