3'64 ANTIENT METAPHYSICS. Book V. 



And there Is a further analogy that, I think, may be obfcrved be- 

 twixt tlie Motions of Animals, or of fuch Bodies as the Magnet and 

 Iron, and the Motion of Projediles ; for the impreffion of external 

 obje«fl;s upon the Organs of Senfe of the Animal cannot properly be 

 laid to be the Caufc of the Motion of the Animal, but is rather the 

 Occafion of it ; for it is the Mind in the Animal that is truly the 

 Caufe of the Motion ; which Caufe operates upon occafion of the 

 impreffion of external objedts upon the organs of the Animal. In 

 like manner, the loadftone is not the Caufe of the Motion of the 

 iron, nor the Iron of the Motion of the loadftone ; for it is impof- 

 fible to conceive that Bodies can operate upon one another at a di- 

 ftance, or otherwife than in contadl : But there is a principle of ac- 

 tivity in the Loadftone and the Iron, which, upon occafion of their 

 being prefented to one another, at a certain diftance, makes them 

 move towards one another. And I fay there is the fame principle 

 in the Body Impelled, which makes it move in a ftraight line, upon 

 occafion of the impulfe. And there a;re in Nature many other oc- 

 cafional Motions by which Bodies are moved, not only to one ano- 

 ther, \)\\X.fvom one another. At the fame time, if any one choofe to 

 call the impulfe the firft or remoter caufe of the Motion, as I have 

 hitherto confidered it, I have no objedion ; for, though it be not 

 the Moving Power, and therefore certainly not the immediate Caufe 

 of the Motion, yet it is a Caufe, in the moft general fenfe of the 

 word, being that without which the event, called the efFedt, could 

 not have happened. But, by whatever name we call it, we ought 

 carefully to diftlnguilh it from the Motive Principle which carries 

 on the Body, fince, by not making that diftindion, it appears that 

 the Newtonians have fallen into the error concerning the Eternity of 

 Motion produced by Impulfe. 



And thus, I think, I have proved, that my hypothefis of Mind 

 being the Moving Power of the Body impelled, is not afTumed 



merely
