The Motion in a Circle

It is not possible for anything to be moved through an infinite right line since that which is thus infinite does not exist. The perfect however is prior by nature by reason and by time to the imperfect and the incorruptible to the corruptible. In these there must necessarily be standing still but if there is standing still the motion is corrupted chapter 14. For every relation as we have before observed is either in a circle or in a right line or mixed from both these it is necessary however that those should be prior to these.
