Division of the Use and Objects of the Faculties of the Soul into Logic 

 and Ethics. Division of Logic into the Arts of Invention, Judg-

*" ^HE doctrine of the human understanding-, and of the 



human will, excellent King, are like twins ; for the purity 



of illumination, and the freedom of will, began and fell 



together ; nor is there in the universe so intimate a sympathy, 



as that betwixt truth and goodness. The more shame for men 



of learning, if in knowledge they are like the winged angels, 



but in affections like the crawling serpents, having their minds 



indeed like a mirror ; but a mirror foully spotted. 



The doctrine of the use and objects of the mental faculties 

 has two parts, well known and generally received; viz., logic 

 and ethics. Logic treats of the understanding and reason, and 

 ethics of the will, appetite, and affections ; the one producing 

 resolutions^ the other actions. The imagination, indeed, on 

 both sides, performs the office of agent, or ambassador, and as- 

 sists alike in the judicial and ministerial capacity. Sense com- 

 mits all sorts of notions to the imagination, and the reason 

 afterwards judges of them. In like manner reason transmits 

 select and approved notions to the imagination before the de- 

 cree is executed : for imagination always precedes and excites 

 voluntary motion, and is therefore a common instrument, both 

 to the reason and the will, only it has two faces: that turned 

 towards reason bearing the effigy of truth ; but that towards 

 action the effigy of goodness ; yet they are faces :

 ing invested with, or, at least, usurping no small authority, be-
