486 ANTIENT METAPHYSICS. Book V. 



praedlcate and fubjed: were generals ; and tbofe of which the prae- 

 dicate was a general, but the lubject a particular thing. Thefe, again, 

 I lubdivided into luch whofe lubje(ii was a particular corporeal thing, 

 and fuch whofe fubje:t was a particular mind. Of all the other kinds 

 of proportions 1 have already fpokca. And it only remains that I 

 fliould fay fomeihing of the laft kind. 



Every particular body is the objed of fenfe, and of fenfe only; 

 and, for that reafon, and on account of its perifhable nature, it ne- 

 ver can be the fubjedt of fcieuce. Mind, on the other hand, whe- 

 ther general or particular, is the obje£t only of intelledt ; for it cannot 

 be apprehended by fenfe, nor otherwife conceived but by intellect. 

 And as it is, of its nature, eternal and incorruptible, there is nothing to 

 hinder even a particular mind to be the fubject of fcience and de- 

 monftration. And though we do not perfedly know the fubltance 

 or efTence of mind, any more than of body, yet, knowing perfectly fome 

 efTential properties of it, we can, from thence, by ftrid demonftration, 

 deduce others. Thus, for example, we know that a^ivity is of the 

 eflence of mind ; from which we have already feen, that many impor- 

 tant confequences follow, and many more will be deduced from it, 

 when we come to treat of God and Nature. 



Again, mind is, by its nature, immaterial : What is immaterial has 

 no parts : And what has no parts cannot be moved. This is a propo- 

 fition that I have taken for granted in the preceding part of this 

 work; "but, if any body fhould doubt of it, it may be thus eafily demon- 

 flrated from the nature of motion : What is moved has its parts 

 fucceffively in different parts of fpace : What, therefore, has no parts, 

 cannot be moved. And thus we conclude, as Ariftotle does, that no 

 particular mind, fuch asthe human, can be moved diredly, immediately, 

 or of itfelf, and by its own nature, but by accidenty that is, by its 

 happening to be conjoined with another fubilance by its nature 

 moveable, viz. body, along with which it is therefore moved.
