Class seventy two

This class discusses the difference between יש מיש, where the material already is and all you are doing is changing the shape, and יש מאין where there is real creating going on. יש מיש can be done once for always. יש מאין must be perpetual. Aristotle held that יש מאין is נמנע. The Rambam considers it the deepest idea of truth. The Alter Rebbe begins his שער היחוד והאמונה where the מורה נבוכים  ends: יש מאין must be constant.
