296 THE GENESIS OF SPECIES. [CHAP. 



human conceptions are but faint and obscure adumbra- 

 tions of corresponding ideas which exist in the mind of 

 God in perfection and fulness. 1 



The theist, having arrived at his theistic convictions from 

 quite other sources than a consideration of zoological or 

 botanical phenomena, comes to the consideration of such 

 phenomena and views them in a theistic light without of 

 course asserting or implying that such light has been 

 derived from them, or that there is an obligation of reason 

 so to view them on the part of others who refuse to enter 

 upon or to accept those other sources whence have been 

 derived the theistic convictions of the theist. 



But Mr. Darwin is not so inconsequent as to argue 

 against metaphysical ideas on physical data only, for he 

 employs very distinctly metaphysical ones; namely, his 



1 The Rev. Baden Powell says: "All sciences approach perfection as 

 they approach to a unity of first principles, in all cases occurring to or 

 tending towards certain high elementary conceptions which are the repre- 

 sentatives of the unity of the great archetypal ideas according to which 

 the whole system is arranged. Inductive conceptions, very partially and 

 imperfectly realized and apprehended by human intellect, are the ex- 

 ponents in our minds of these great principles in nature." 



"All science is but the partial reflexion in the reason of man, of the 

 great all-pervading reason of the universe. And thus the unity of science is 

 the reflexion of the unity of nature, and of the unity of that supreme 

 reason and intelligence which pervades and rules over nature, and from 

 whence all reason and all science is derived." (Unity of Worlds, Essay i., 

 ii. ; Unity of Sciences, pp. 79 and 81.) Also he quotes from Oersted's 

 "Soul in Nature" (pp. 12, 16, 18, 87, 92, and 377): "If the laws of 

 reason did not exist in nature, we should vainly attempt to force them 

 upon her : if the laws of nature did not exist in our reason, we should 

 not be able to comprehend them." .... "We find an agreement 

 between our reason and works which our reason did not produce." .... 

 " All existence is a dominion of reason." " The laws of nature are laws of 

 reason, and altogether form an endless unity of reason ; . . . . one and 

 the same throughout the universe."
