82 ANTIENT METAPHYSICS. Book II. 



Co perfcd. What then is their Idea ? It is certainly fomething 

 more than tlie fimple perception of Senfe ; for they know, in the 

 Jifjl place, of what Senfe it is the perception ; that it is of the Senfe 

 of Sight, and of none other : 2d/j, That it is perceived at a cer- 

 tain diftancc, not too near, nor too far oil': ;^J/f, That it cannot be 

 perceived without Hght, and therefore not in the dark. The brute 

 knows none of thefe things, and therefore he has no Idea of the 

 Colour White ; and this is the cafe of a very young child, before he 

 has got the ufe of Intelledl. 



I will give the example of another Senfatlon, of a kind quite 

 different, which is not perceived at a diftance like Colour, nor is not 

 confined to one organ of Perception, but is diffufed all over the 

 body, and is perceived in the dark as well as in the light. This is 

 Touch, of which every animal has the Perception, though \\t may 

 want every other Senfation. But he has not, therefore, the Idea of 

 it, unlefs he can diftinguifh it from the Senfe of Sight, and the o- 

 ther fenfes, by its different manner of operating : And the fame is 

 to be faid of the Perceptions of the other Senfes, of Tailing, Smel- 

 ling, and Hearing. In fhort, unlefs the Mind can diftinguifli 

 the Perceptions of one Senfe from thofe of another, even 

 from thofe that appear to refemble it the moft, as Tailing refem- 

 bles Touching more than the Perception of any other Senfe, and is 

 able to give fome account of the difference, it is no more than a 

 fimple Perception of Senfe, fuch as a Zoophite has, not an objedt 

 of Intelledt. 



I will give one example more in the Perception of any particular 

 Figure, which enters by two Senfes, the Touch and the Sight. All 

 that I perceive by the Touch is a certain fubftance, which refifts my 

 Touch : But this is no more than a Senfation, though I perceive 

 that this refiftance is not every where, but in a certain fpot. Again,
