Chap.IV. ANTIENT METAPHYSICS. 343 



The moft obvious properties of things are thofe I have mentioned, 

 viz. number^ figure^ and motion^ which are the fabjedts of the particu- 

 lar fciences I have named. But there are many other properties of 

 things, vi^hich, not being of a nature fo fimple or determinate, and 

 therefore not eafily abflraded, have not hitherto been made the fub- 

 je€t of any particular fcience, fuch as hitter SLud/weetj cold and hot 

 moiji and dry, Thefe, and fuch like, are all thrown in together, un- 

 der one category, to which the name of quality is given. In like 

 manner, all adions and energies, however different they may be, are 

 clafled under the category of a^ioji. And fufferings, likewife, however 

 different in kind, are all comprehended under the category of fuffer-^ 

 ing. And fo on, with refped to the reft of the nine categories of acci- 

 dents, all v/hich are inherent in the firft chief category, viz. fubftance 

 which does not belong to any particular fcience, but only to this uni- 

 verfal fcience ; the nature of which is, that it comprehends not only 

 what is the fubjed of particular fciences, but alfo thofe things which 

 hitherto have not been reduced to fcience. 



The metaphyfical ideas I have hitherto mentioned are all abftraded 

 from matter ; more abftraded, indeed, than the mathematical, and 

 more general ; and, confequently, nearer the principles and the original 

 of the univerfe. But the ideas I am now to mention, are offubftances 

 altogether immaterial, which, as I have faid, are the proper fubjea: of 

 metaphyfics. The only pafTage which can lead the philofophcr into 

 this invifible world is motiofi-, {or, having learned to diflinguifh betwixt 

 what movesy and is moved^ he foon difcovers that the moving power 

 of this univerfe cannot be material.. 



It was by this road that the great philofophers of antiquity afcend- 

 cd to the Firft Caufe and Author of all motion, himfelf unmoved and 

 "unchangeable, 



flabilifque manens, dat cundla moveri.
