156 THE IMMORTALITY OF ANIMALS 



necessary for its existence disappears. Now if an 

 infant has a soul, according to theology, while 

 under the government of instinct, it is certainly the 

 vital cause of all its actions. So that instinct is the 

 immortal part of the child. 



In the lowest types of the human race, instinct 

 forms the human constitution, and there are in- 

 stances where there are no traces of any faculty 

 above instinct. If such types of mankind have 

 souls, and are governed by only one form of vital 

 energy, it is certainly soul energy. 



The same argument may be used in the case of an 

 idiot or lower animals. "We perceive the diversified 

 operations of the soul and call this energy by differ- 

 ent names according to different manifestations. 

 When inferring truth from truth, it is called un- 

 derstanding ; when tracing a cause to an effect, it 

 is reasoning ; when contemplating the future, im- 

 agination ; when reviewing the past, memory ; 

 when choosing or refusing, will ; and when spon. 

 taneous, instinct. 



As they all refer to the phenomena of vital 

 action, and there is but one soul to each being, it 

 must be true that the soul has many faculties, or 

 else it has nothing to do in controlling the body.
