Chap. X. ANTIENT METAPHYSICS. 175 



ever was produced by any one man, is taught in no Univerfity in 

 Britain, and is entirely out of fafhion. As it is fo great and fo ufe- 

 ful a work, if what 1 have faid of it in the preceding chapter could 

 revive it, and bring it again into ufe, I fhould think that 1 had made 

 fome progrefs in this great attempt I have made to revive antient 

 philofophy. 



Before I conclude this chapter upon ideas, I will make fome ob- 

 fervations upon a faculty of the human mind, to v>^hich, I think, 

 fufficient attention has not been given by philofophers antient or 

 modern, though it has great influence upon our ideas, and is very 

 ufeful in forming them. The faculty I mean is, what is called in 

 Greek (pctiroca-iu, and in Englifli imagi?iatio?i. It is a faculty which 

 the brutes have as well as we, and which is abfolutely neceiTary for 

 carrying on their animal oeconomy, as I have fhown *. By tliis 

 faculty the images or pidures, as they may be called, of the objeds, 

 which we have at fome time or another perceived by our fenfes, 

 are again prefented to us. It may, therefore, be called a fecon- 

 dary fenfe, fupplying the place of the primary, and often making 

 a greater imprefhon upon us than the primary. 



This faculty of the Phantafia^ v/hich preferves our fenfations, 

 fhould be diilinguifhed from Memory^ which is the cuftodie^ of our 

 ideas ; and, as from our fenfations our firft ideas arife, it was ht that 

 there fhould be a cuftodier for each of them. And our fenfations 

 thus preferved, are of very great ufe to us in forming thofe firfl ideas 

 of particular objeds of fenfe; for unlefs they were retained in the. 

 mind by the phantafia, we could only form thofe ideas when the 

 objeds of fenfe were prefent v/itli us; and as that cannot alwa-^ ' 

 we could not form them fo accurately as we do by the mc : ■ 

 the phantafia.
