the animal mind. And, accordingly, natural philofophy treats of all 

 thefe three lubflances, and of the motions in them produced by mind. 



The next ftep, in the progrefs of our knowledge, is to animals 

 intelligent. Of thefe there is, in tins earth, , only one, viz. man; 

 and it is only by the ftudy of him that we can have any knowledge 

 of what intelligence is : And, as we are of that fpecies ourfelves, 

 we may, by the ftudy of ourfelves, acquire what is the moft per- 

 fect knowledge here below. It was, therefore, not without reafon, 

 that, upon one of the gates of the temple of Apollo at Delphi, the 

 precept, knoisj tljyfdf^ was infcribed.

 higheft philofophy, I mean Theology ; and that is the knowledge 

 of an intellectual mind, not embodied or incorporated with matter : 

 For we can have no knowledge of fuperior intelligences, and far 

 lefs of the fupreme intelligence, unlefs we have formed the idea of a 

 pure immaterial fubftance. But, even from the ftudy of ourfelves, we 

 may form the ideaof fuch a fubftance : For man contains in himfelf the 

 intelledlual, the animal, the vegetable minds, and that mind, which is 

 common to all bodies, and which I call the elemental mind, by which 

 bodies are moved up or down, or in the diredion in which they are 

 impelled, and, joined to all thefe minds, body. In fhort, man is an epi- 

 tome of every thing in nature, and therefore is very properly called a 

 microcofm or little world \ So that the ftudy of him may be faid to 

 be the ftudy of Nature and of the great world ; and particularly of 

 that, which is principal, both in the great world and in his little 

 world, that is intelligence, by which we learn every thin-^ clfe ;
