136 . ANTIENT METAPHYSICS. Book III. 



3^/0, If the Animal Nature did not exift feparately, and if alfo 

 the Intellediial did not exift in that way, it might be thought that 

 the fuppofition of their exifting conjoined in Man was a mere hy- 

 pothefis, and that Man was truly a fimple, uncompounded,fubftance. 

 But we are fure that the Animal cxifts feparately ; and, if we be- 

 lieve in God, we muft believe that Intelledt exifts likewife fepa- 

 rately. And, if fo. What fhould hinder them to exift conjoined ? 

 Body and Mind exift in that way ; and certainly the Animal and 

 Intelledual Minds are not fubftances more different in their natures, 

 than Mind and Body. 



Thus it appears, that, in our various Nature are joined together 

 the Vegetable, Animal, and Intellectual Natures; to which may be 

 adJed a fourth Nature, which I call the Elemental Life. This makes 

 Man the moft wonderful compound here below : And he is truly 

 what the anticnts called him, a Microcofin, or Liitle World ; for we 

 cannot conceive the Great World composed of any other ingredi- 

 ents. And I am perfuaded thefe four are the famous Tetradys of the 

 Pythagoreans; which was thought fo great a myftery of philofophy, 

 that the Pythagoreans fwore by him who firft difcovered to them the 

 Tetra^js, the Eternal Source of ever fioivlng Nature *.

 Know, that the veneration, that the Pythagoreans had for the number/oar, is afcri- 

 bed to its being a fymbol of the progrcfs of Nature in the formation of Phyfical 

 Bodies i the monad ftanding for the point the duad iot the line, the number three 

 for the fimplefl fuperficial figure, viz the triangle, and the nurnberyiur for the 

 fimplefl foiid figure, viz the Triangular Pyramid, confift ng of three fides and a 

 bafe : So th.it the number four completed the progrefs of Nature in the formation 

 of Phyfical Bodies. But though, no domt, the Pythagoreans confidered Arithme- 

 tic as t!'.e Primary Science, and Geometry as nothing more than the application of 

 Numbers to Lines and Figures; yet it is likewife ceitain, that they made Num- 

 bers
