ANALOGIES. 41 



tion of life and of the works of man mere 

 coincidences ? 



Do they not indicate that the intelligence !| 

 and power manifested in the development 

 of the steam-engine are, though infinitely 

 lower in degree, akin to those that evolved 

 successive forms of life, and do they not 

 justify the presumption, that there is a 

 certain analogy between man's method of 

 developing his works and the evolution of 

 life? 



If, then, we are to inquire into Nature's 

 methods, should we not advance most surely 

 by comparison, based on our observation 

 and experience, of the processes of Nature 

 and of man ? 



The homology throughout Nature sug- 

 gests that the laws of the forces which we 

 call life are analogous to those of the forces 

 that pervade inanimate Nature, and are 

 we not bound to assume that in the evol- 

 ution of life there was no effect without 

 a corresponding Cause, nothing spontaneous 

 or accidental ?
