Demonstration. For let A be that which moves 

 the first motion : for it is necessary that there 

 should be something of this kind, because every- 

 thing which is moved is moved by something. But 

 A, if it is that which first moves, will be im- 

 moveable: for that which is immoveable is the 

 leader of all things which are moved. And, since 

 it moves a perpetual motion, it will possess an 

 infinite power of moving ; for finite powers have 

 also finite energies: for energy proceeds from 

 power. So that if its energy is infinite, its power 

 also will be infinite. Hence, that which first 

 moves a circular motion, must necessarily either 

 be body, or incorporeal. But if body, it is either 

 finite or infinite. There is not however an infinite 

 body. And if it is a finite body, it will not pos- 

 sess an infinite power. But the powers of things 

 bounded according to magnitude are finite, as has 

 been demonstrated. Hence, that which first moves 

 a circular motion, is not a body. It is therefore 

 incorporeal, and possesses infinite power. 



THE END.
