organs of sense arc struck by any of the bodies that 

 surround us, and the motion caused thereby continued 

 through the nerves to the brain, the soul, residing 

 there, is suitably affected : God having so closely 

 connected the soul and the body, that on certain mo- 

 tions of the body, (if conveyed to the brain by means 

 of the nerves) certain perceptions of the mind always 

 follow : as, on the other hand, on certain perceptions 

 of the mind, certain bodily motions follow. 



8. They suppose, if these motions, which are by 

 the nerves communicated to the brain, continue there 

 after the objects are removed, the perception of these 

 is imagination : which, if it occurs after it has ceased, 

 is then stiled memory. Others suppose, that imagi- 

 nation results from the motion of the animal spirits, 

 through fhose traces which were made in the brain, 

 while the outward objects were present ; and memory, 

 from the spirits moving through them afresh^ after 

 some intermission. 



9. Once more. They suppose there are two facuU 

 ties in the soul ; one that is passive, the Understand-

 and knows and reflects on its own operations : 'the 

 other active ; the Will, by which we incline to good, 

 and are averse to evil. The affections -are only 

 the Will exerting itself variously on various objects. 



10. To speak freely upon the matter. I know the 

 body of man is contrived with such exquisite wisdom, 

 that he is able, by means of the organs of sense, to 

 perceive outward objects ; to continue those percep- 

 tions, to recal them after they are gone, and by a 

 reflex act, to know what passes in his mind or body. 

 But I know not how to account for any of these 

 things. 



11. That the soul is immaterial, is clear from hence 

 that it is a thinking substance. If it be said, " God
