XII.] THEOLOGY AXD EVOLUTION 299 



from the inorganic. But all science tends to unity, and this 

 tendency makes it reasonable to extend to all physical ex- 

 istences a mode of formation which we may have evidence 

 for in any one of them. It therefore makes it reasonable 

 to extend, if possible, the very same agency which we find 

 operating in the field of biology, also to the inorganic world. 

 If on the grounds brought forward the action of intelligence 

 may be affirmed in the production of man's bodily structure, 

 it becomes probable a priori that it may also be predicated 

 of the formative action by which has been produced the ani- 

 mals which minister to him, and all organic life whatsoever. 

 Nay, more, it is then congruous to expect analogous action 

 in the development of crystalline and colloidal structures, 

 and in that of all chemical compositions, in geological evo- 

 lutions, and the formation not only of this earth, but of the 

 solar system and whole sidereal universe. 



If such really be the direction in which physical science, 

 philosophically considered, points ; if intelligence may thus 

 be seen to preside over the evolution of each system of 

 worlds and the unfolding of every blade of grass this 

 grand result harmonizes indeed with the teachings of faith 

 that God acts and concurs, in the natural order, with those 

 laws of the material universe which were not only instituted 

 by His will, but are sustained by His concurrence ; and we 

 are thus enabled to discern in the natural order, however 

 darkly, the Divine Author of Nature Him in whom " we 

 live, and move, and have our being." 



But if this view is accepted, then it is no longer abso- 

 lutely necessary to suppose that any action different in kind 

 took place in the production of man's body, from that which 

 took place in the production of the bodies of other animals, 

 and of the whole material universe. 



Of course, if it can be demonstrated that that difference 

 which Mr. Wallace asserts really exists, it is plain that we
