Intellection or judgment consists in giving a-sent 

 to some proposition, such as " Zeid is standing," 

 or "Zeid is not standing." 



Each of those, namely, perception nnd intellection, 

 are necessarily divided into two kinds, viz. Those ac- 

 quired by intuition without any previous argument or 

 proof, and therefore called intuitive; and those ac- 

 quired by investigation and reasoning, and therefore 

 called demonstrable. We have therefore estabHshed 

 four distinctions, viz. perceptions intuitive, and per- 

 ceptions demonstrable : or in other words, 



1 . The known perceptible. 



2. The unknown perceptible ; 



and intellection or truth intuitive, and intellection 

 or truth demonstrable ; in other words, 



1. The known demonstrable. 

 1. The unknown demonstrable. 



The idea of heat and cold, is an example of the 



known perceptible. 

 The idea of angels and genii, is an example of 



the unknown perceptible. 



The proposition that the sun shines, is an exam- 

 ple ot the known demonstrable ; and 



The proposition that the world was created, and 

 that there is a Creator, is an example of the 

 unknown demonstrable. 



In the language of logicians, examination or in- 

 spection is the contemplation of the thing known to 

 obtain a knowledge of the thing unknowr ; that is 

 to say, the contemplation of the known perceptible, 

 and the known demonstrable to obtain a k noivledge 

 of the unknown perceptible and unknown demon- 

 strable ; and as mistakes often happen in this investi-
