 iecn, they are accurately diftlnguifhed. But the philofophy of Plato 

 and Ariftotle has very clearly diftinguifhed them ; and, particularly, 

 the commentators upon Ariftotle, have laid down the diftindiioii 

 mofl: clearly, as I have elfewhere Ihown *. This, as well as other 

 things, Plato and Ariftotle have taken from the Pythagorean School, 

 in which the doctrine of the four Subftances, of which I make Alan 

 to be compofeJ, is moft clearly laid down, and particularly the di-

 See alfo what the fame author fays, p. 57. and 58. And JambHchus, in his Life of 

 Pythagoras, p. 184. tells us that oyr chief bufmefs here below is to free our Intellec-
