Chap. IV. ANTIENT METAPHYSICS. loi 



headed under one head, — The Form or the Nature of the thing it 

 contemplates, which we muft be able to dlftinguilh from the Matter 

 and thofe material qualities that afFeft the fenfes. 



Thus, it appears, that, as Man has one gno/lic power more than 

 the Brute, fo he has, correfpondent to it, likewife one oreclic power 

 more ; and, therefore, he is, in both ways, eflentially diftinguiflied 

 from the Brute. 



This defire of knowledge belongs, as Ariftotle has obferved, not 

 only to the philofopher, but to all men more or lefs * ; and the 

 reafon is plain, that it is effential to Intelled: : So, if there be any 

 thing of the human form entirely void of curiofity or defire of 

 knowledge, we need not hefitate to pronounce that animal no Man, 

 but a Brute, who, having no intelled, has no defire of knowledge; 

 all his defires being fuch as belong to the Animal Nature, and tend 

 only to the prefervation of the individual or continuation of the 

 race.
