vis iftfita in the Body, and not by Mhid. — The iron is moved alfo 

 only occafionally when tlie loadftone is within a certain diftance of 

 it, and not till then : And, fhall we fay that the-iron is moved by a 

 *vis injita^ and not by Mind \ If we go on in that way, muft we 

 not maintain that all the i>'Iotions in the univerfe are produced by a 

 nj'is infita in Bodies? And, as all the Motions in the univerfe are evi- 

 dently for fome end, and conduced by certain rule and meafure, 

 muft we not give to matter Intelligence as well as a Power of mo- 

 tion ? and, indeed, when the Newtonians fay that the Body moves 

 itfelf in a ftraight line, in which it had never been moved be- 

 fore, and this uniformly with the fame velocity as well as in the 

 fame dired:ion, is not this giving to matter the power of doing 

 things by rule and meafure, which cannot be without intelligence ? 

 And it is but to fuppofe that Body performs other Motions in the 

 fame way, and then v/e have complete the philofophy of Strato the 

 Peripatetic, which was certainly the moft rational fyftem, (if any 

 fyftem of Atheifm can be faid to be fo), that ever was devifed, but 

 which 1 do not fuppofe that the Newtonians are inclined to a.- 

 dopt '^. 



Another confequence of Motion, once begun, being carried on 

 by a power inherent in Body and effential to it, is, that there 

 can be no fnch thing as Motion by trufion in vacuo ; for other- 

 wife it would not be true, in every cafe, that Motion once be- 

 gun goes on by itfelf, becaufe Motion by trufion ceafes as foon as 

 the Body protruding ceafes to ad ; therefore there is but one way 

 in which Body ading upon Body can produce Motion in vaciio^ and 

 that is, by pulfion. Of this I have faid a good deal elfewhere, and, 

 I think, 1 have fhown that it is a propofition as contrary to found 

 •philofophy as to common fenfe t*
