has been once Imprefled upon it, bat begin a new Motion of a quite 

 different kind ; and this not once, but at different times, and in dif- 

 ferent diredions ; a proportion wliich I hold to be mofl dangerous 

 to the dodrine of Theifm, and, indeed, leading diredly to Materl- 

 alifm. For it appears to me to be reviving the philofophy of Epicu- 

 rus, who maintained that there is a principle of Motion in Matter 

 different from Mind ; and, therefore, that all the Motions in the 

 univerfe are produced by material neceiTity. And further, it is giving, 

 as I before obferved *, a principle of intelligence, as well as of Mo- 

 tion, to Matter ; for there can be nothing done uniformly, or by cer- 

 tain rule and meafure, Vv^ithout Intelligence. 



If they will not give up the fyftem, which leads, by neceflary 

 confequence, to fuch extraordinary proportions, they fhould at Icatl 

 endeavour to defend it by more plaufible arguments than any I have 

 yet heard, and, in that way, to prove themfelves, if not good phi- 

 lofophers, at leaft good fcholars, and learned in the antient arts of 

 fophiftry, fo as to be able to argue againfl: Motion bv Mind as fub- 

 tilely, as Zeno of old did againft Motion in general. If they will 

 do neither, they muft forgive me for thinking that they are mere 

 mechanics, and, that whatever value they may put upon the fcience 

 of mechanics, even a fcientific mechanic is not more different from 

 a common mechanic, than a theoretic geometer is from a land mea- 

 furer. 



There is another thing I would beg leave to recommend to them, 

 and that is, to deal more in diftindions, and not to forget that old 

 maxim of the Schools, qui bene dijlingnit^ bene docet • which is ne- 

 ceffary in all branches of philofophy, and efpecially in metaphyfics. 

 This is a thing, in which I obferve all thofe, who have not fludied the 

 antient philofophy, are defective ; and particularly the Newtonians, in 

 this inquiry concerning the beginning and continuation of Motion,
