" No shadow of reason can be assigned for the belief that variations 

 which have been the groundwork, through natural selection, of the 

 formation of the most perfectly adapted animals in the world, were 

 intentionally and specially guided" (Far. Ans. and Pts., 1st ed. 

 vol. ii. 431). 



" The old argument from design in Nature fails, now that the law 

 of natural selection has been discovered. There seems to be no more 

 design in the variability of organic beings, than in the course which 

 the wind blows" (Life and Letters, i. 309). 



ARISTOTLE.

Since we see several causes existent in nature, as the final cause 

 on the one hand, and the efficient cause on the other, it is for us to 

 determine in their regard, which is by nature the first, and which 

 the second. But that is seen to be first which we call the final 

 cause, design. For this is reason, but reason is the principle alike 

 in the things of art and in the things of nature. In these latter, 

 however in the works of nature, the final cause and the good is 

 more plainly manifest than in the works of art, for necessity does 

 not similarly obtain in them (De partibus, i. 1, 2).
