generates mechanical power. And thus a bridge of connection is 

 estabhshed between physical and moral causation, which enables 

 us to pass without any sense of interruption or inconsistency from 

 the scientific to the theological interpretation of Nature, as here 

 formulated :

With these views of the relations between science and theology, 

 I have never myself been able to see why anything else than a 

 complete harmony should exist between them. True it is that 

 there have been, from time to time, men of science, who, from 

 what I believe to be an equally limited and illogical conception of 

 the subject, have drawn the conclusion that there is " no room" 

 for a God in Nature ; the " properties of matter " being, in their 

 view, all-sufficient to account for the phenomena of the universe 

 and for the powers and actions of the human mind. But this 

 seems to me only a natural reaction against what all history 

 teaches, as to the constancy with which, ever since science 

 emancipated itself from theology and set up for itself, it has been 

 hampered and impeded in its search for the truth as it is in Nature, 

 by the restraints which theologians have attempted to impose upon 

 its inquiries. The Romish Church, adopting the philosophy of 

 Aristotle into its own theological system, opposed as heretical 

 every attempt to call in question the authority of Aristotle, even 

 as to matters of fact ; and while it could not repudiate the proof 

 afforded by the experiments of Galileo, that a weight of lolb. does
