'fay likevvifc of them, that what moves them, be it internal or external, 

 7nind or nuitUr^ is fometliing difi^rent from them. 



As to what is faid of mind nwuing itfdj^ 1 have ah*eady fhown 

 in what lenl'e wind can be faid to be inonjed"^ : And it is evi- 

 dent that it caniiot be faid to be moved in the fenfe in which body is 

 moved : For Ioi\J. motion^ as 1 have fhown, is elfential to all the mo- 

 tions oi body. Now, i[t 7/;i72c/ be immaterial, indivifible, and without 

 parts, as 1 hope in the fcquel to dernonftrate it to be, it is incapable of 

 local inotion ; and, if it cannot be moved^ it is evident that it cannot 

 move itftlf ; for, to be moved^ and to move, as I have faid, are rela- 

 tives, which II uft exift together, or not at all. 



As to Plato's definition of mind, it is, as fhall be fhown in the next 

 chapter, inaccurate in the expreffion. And indeed, although, according 

 to that general and mofl: comprehenfive definition of motion given by 

 Ariftotle, inferior minds may, as I have obferved, be faid, in a certain 

 fenfe, to be tiioved, when they change from a (late of reft to a ftate 

 of a6lion, or from one energy to another f, it were to be wiihed that 

 the term which, in all fenfes, is applicable to body, and which, even 

 by phllofophers, is commonly applied only to body, fhould never be 

 applied to mittd ; but that we fhould call thofe changes to which it is 

 liable, its aftions and energies, not its motions ; and Ihould fay, that it 

 is, by its nature and effence, a^live, and that it Juffers only by its 

 connexion with the body. 



And here we have again that diftindion made by fome antient phi- 

 lofophers, quoted above \, betv/ixt mind dnd body, viz. that the oi.e acis, 

 and the other is a^/ed upon ; a diftindion which runs ttirough all na- 

 ture, and is t:ie fundamental principle, in my apprehenfion, ot the fy- 

 ftem of the univ<:rfe. It is true, indeed, that body feems to acl, as 

 well as \.o Jujjtr ; but then it ads only as the inftrument of 7nuid, and 

 cannot, in ftrid pri-^riety, be faid to aSi any more than the lever that 



move s
