NATURAL THEOLOGY 1 13 



substance, and regards mind as but a property or 

 particular manifestation of matter. The other class 

 contends that behind the pressure which produces 

 the motions and sensations of animals is a spiritual 

 nature called soul ; and that the material and the 

 mental nature may be regarded from a dualistic 

 point of view as a perfectly distinct kind of 

 reality. 



The greater number of modern scientists adopt 

 the latter scientiiic hypothesis, and contend that the 

 soul is external to the nervous mechanism which it 

 sets in motion, and that there is an external agent 

 in all animal life independent of the body. It is an 

 easy matter, when considering the two schools of 

 philosophy, to see where modern materialism and 

 theology separate. I have for many years been in- 

 vestigating both sides of the question and am thor- 

 oughly convinced that life, or the power which gives 

 motion and sensation, must come from without, and 

 is independent of the nervous mechanism ; and from 

 this life potency proceeds organization, for there 

 cannot be life without organization to receive it. 



The cause of vital movement must exist before 

 the movement. Nothing can exist in an effect 

 which did not previously exist in the cause.
