Mind and Body are each of them Subftances.— y/// Things Subftances 

 or Accidents. -Subftances knoivn to us only by their Operations -De- 

 fnitlon given /Body and om'md^.—yld'v ant ages of thoje Definitions. 

 —Mind docs not al-ways move,— nor is Body alivays moved— but 

 the Definition is from the Vov;er.— Difficulty of defining Mind ac 

 knoivkdged by the Jntients.

O L D I N G, therefore, that there are two Subftances in the 

 univerfe, one Mind, the other Body, the next thing to be in- 

 quired into, is, What thefe Subftances are ? That they are Subftances 

 I hold to be certain ; for, as every thing in nature is either Sub- 

 ftancc or Accident, they muft be either one or other. Now, they 

 are not Accidents, (for of what are they Accidents ?) ; they muft, 

 therefore, be Subftances. 



Thofe who have not learned logic will be difpofedto fay, that this 

 is a mere logical diftindlion, without any foundation in the nature 

 of things ; but thofe who have learned their logic know that all lo- 

 gical diftiniTtions are taken from the nature of things ; for from what 

 other fource can they be taken ? — and that every Quality or Acci- 

 dent, of every kind, muft belong to fome fubjed, and be inherent In 

 fomething that is called Subfiancc. And thofe who have ftudied 

 the nature of truth and evidence, know very certainly, that we have 

 not the knowledge of the exiftence of any thing, not even of our- 

 felvcs, but by its operations ; for we do not know that any 

 thing without us ex:fts, except by its operations upon the or- 

 gans
