224 The Wisdom of GO D Part IL 

 that it is plain that Nature intended us to walk 

 as we do, and not upon all four. 



2. I argue from the SifuSy or Pofition of our 

 F^ces ; for had we been to walk upon all four, 

 we had been the moft prone of all Animals, our 

 Faces being parallel to the Horizon, and look- 

 ing diredtly downwards. 



3. The Greatnefs and Strength of the Mufcles 

 of the Thighs and Legs above thofe of the Arms, 

 is a clear Indication that they were by Nature in- 

 tended for a more difficult and laborious Adion, 

 even the moving and transferring the whole Bo- 

 dy, and that Motion to be fometimes continued 

 for a great while together. 



As for that Argument taken from the contrary 

 Flexure of the Joints of our Arms and Legs to 

 that of Quadrupeds, as that our Knees bend for- 

 ward, whereas the fame Joint of their hind Legs 

 bends backward ; and that our Arms bend back- 

 ward, whereas the Knees of their fore Legs bend 

 forward ; although the Obfervation be as old as 

 Jrijlotle, becaufe I think there is a Miftake in it, 

 in not comparing the fame Joints (for the firft 

 and uppermoft Joint in a Quadruped's hind Legs 

 bends forward as well as a Man's Knees, which 

 anfwer to it, being the uppermoft Joint of our 

 Legs, and the like mutatis mutandh may be faid 

 of the Arms) I fl:iall not infift upon it.
