 exact truth that can be expected in those theories ; for as 

 the same phenomena in astronomy are satisfied by the 

 received astronomy of the diurnal motion, and the proper 

 motions of the planets, with their eccentrics and epicycles, 

 and likewise by the theory of Copernicus, who supposed 

 the earth to move, and the calculations are indifferently 

 agreeable to both, so the ordinary face and view of expe 

 rience is many times satisfied by several theories and 

 philosophies; whereas to find the real truth requireth 

 another manner of severity and attention. For as Aris
