Document Summary

Ordering the motions", or making the course of the stars conform to what is seen" in. Tolemey"s system is depends on 2 principles: epicycles, eccentric spheres or equants (the more stretched out an object is, the more eccentricity it has) According to maimonides, both those principles are entirely outside the bounds of reasoning. & opposed to all that has been made clear in natural science". Problem: epicycles change their place completely, contradicting the assumption that movements in the heavens do not change their place --- but aris. Says that all circular motions revolve around a common centre. Aristotle doesn"t: everything that moves with the circular movement, except the 1st sphere (stellar sphere), is observed to be passed & to move with more than 1 motion". We learn from aristotle that it is necessary that the earth should be immobile & that there should be some immobile thing around which circular motion takes place.
