Chap. I. ANTIENT METAPHYSICS. 2?i 



man and that of the brute, is a thing not without difficulty, but I 

 think of importance, as every thing relating to mind is; for it is 

 mind that has produced this univerfe, and for;ned it into a fyftem. 

 And as the fyftem of the univerfe was formed by mind, fo every 

 part of it is. executed by mind ; for it is by motion that all the ope- 

 rations of nature in this univerfe are performed. Now I hope 1 

 have proved, to the reader's fatisfadtion, that all the motions of the 

 univerfe proceed originally from mind ; for, though motion be no 

 doubt produced by one body afting upon another by pulfion, tru- 

 fion, or by drawing it, yet the body, which in this manner afts upon 

 another and puts it in motion, muft itfelf be firft moved ; and 

 that can only be by mind. 



And here the reader may obferve, in paffing, the different ways in 

 which body and mind move bodies. Body, as I have faid, moves ano- 

 ther body by pulfion, trufion, or by drawing it; but in none of thefe 

 ways can we conceive mind moving body. It cannot therefore 

 move body by any outward application to the body, but muft move 

 it by adting upon it inwardly, and not upon the furface of it, as 

 body adls upon body. Now I think this fliows an eflential difference 

 betwixt mind and body ; for we cannot conceive body entering into 

 body without making a breach in the body. And if we could con- 

 ceive it entering the body in this way, how can we conceive it 

 moving the body from within, and not one part of the body but 

 the whole body, fo as to make it go from place to place, and 

 to move in every direction, up or down, from one fide to ano- 

 ther, and in a ftraight or a curve line. And this, as I have 

 obferved already *, may give the moft vulgar man an idea of 

 an immaterial fubftance, which otherwife he cannot eafily con- 

 ceive, and of which it does not appear that even the Greeks had 

 any conception till Pythagoras came among them, and brou^Vt phi-
