204 ANTIENT METAPHYSICS. Book IIL 



v'ith mntter, from which we are obliged to difengage it, and to 

 finv^le it out as we would do a friend or old acquaintance out of a 

 crcuLl ; for, in this world, all things are fo mixed with all things, 

 as an antient philofopher ohferved, that it requires a great deal of 

 accuracy and attention to fmgle any one idea out of a great ma- 

 ny, and to prefent it to the mind by itfelf. And, indeed, I fhould 

 think it inipoffible, that a creature, with only the capacity of intel- 

 lect, fhould be able, even with the affiftance of his fenfes, to difcover 

 the ideas of things wrapt up, as they are, with the integuments of 

 matter, and to put them together fo as to form arts and fciences, 

 without the aid of reminifcence. 



Having mentioned intellect and fenfe, as two faculties of the mind 

 quite diftind, as diftinct as what is perceived by them, namely, ideas 

 and perceptions of fenfe, it may not be improper, for the fake of 

 thofe who know nothing of philoibphy, except from what they 

 have read in Mr Locke, who plainly confounds ideas and fenfations, 

 to explain, in few words, the difference betwixt fenfe and intelled: : 

 And, I fay, they are fo different, not only in the manner of their 

 operation, but in the objed:s upon which they operate, that what 

 the one perceives the other does not perceive; for fenfe does not 

 perceive ideas, which are the objeds of intelled:, any more than in- 

 teiled perceives the objeds of fenfe, that is the qualities of bodies ; 

 For a blind man, let his intelled be ever fo perfed, cannot perceive 

 colours, any more than a deaf man can hear founds. And again 

 as the fenfe cannot perceive the idea of any individual thing, but 

 only the material form, far lefs can it gencralife or form the idea of 

 a fpecies, becaufe fenfe cannot compare or perceive a whole in any 

 thing, but only receives the impreffions made upon it by the adion 

 of corporeal objeds. And this leads us to obferve not only the dif- 

 ference in the objeds of thofe two faculties of the mind, but alfo in 

 the manners of their operation : For fenfe does not operate by itfelf,
