78 ANTIENT METAPHYSICS. Book. 11. 



per to apply it to the Greek word ^i.vx,n, though it appears that Thales, 

 the founder of the Ionian fchool, was not fo fcrupuious, but afcribed 

 the 7notio?i of the atcradtion of the iron by the loadftone to mind or 

 ^•'Aji* And, in the fame way, he, no doubt, accounted for all the other 

 phaenomcna of nature of the fam.e kind. 



Laflly^ When he tells us that the mind is i\\eJon?i of an organized 

 hody^ he tells us what is true, but he does not tell us enough ; for he 

 does not tell us in what \.\\\%fo>m confifts : And it is, as if one fhould 

 fay, that the dcfi:iition of any one thing was \\.s form, without letting 

 us know what x\\q form is. Now, I have exprelfeJ, in my definition, 

 what that form is, and have laid, that it is a ?7iotive poijuer) a defini- 

 tion, which, I think, mort perted;ly diftinguifhes mind irom.body, and 

 comprehends every kind of mind frv)m the higheil to the lowelb. And 

 fo much for Ariftotltr's definition of mind. 



Plato*s definition is, * That mindh what \% fdf-moved\\^ thereby di- 

 ftinguilliing it from tody^ which is either moved by mind, or by another 

 body ; for both Plato and Ariftotle, and all philofophers, both antient 

 ^nd modern, who are not atheifts, agree in this, that body cannot mo'vs 

 itfelf. Agalnft this definition of Plato, Ariftotle has argued at great 

 length, in his firft book De Anima, cap. 3. where he maintains, not 

 only that the mind is no\. felf -moved, bat that it is not moved at all. 

 And he adds, that it is impofTible, by its nature, that it can be moved. 

 And, upon the fuopofition, that Plato meant bodily motion, in which 

 fenfe Ariftotle underftands him, it is evident that mind, not being a 



mate^ 



the works of nature and thofe of art, that the former have the principles of motion in 

 themfelves, and the latter are moved from without; lib. 2. phyf. cap. i. And not onlydoes 

 this principle move, but it moves with defign, and for a certain purpole, in the fame 

 manner as art moves the materials upon which it works. It is, fays he, as if the art 

 of ftiip-building was in the wood. This, he adds, is mofl manifeft in the inftance of 

 a phyfician curing himfelf; for that is likefl: of all to nature. Lib. 2. Phyf. cap. y in

 is, * capable of being moved by it/elf,*
