The Only Hebrew Commentary on Metaphysics Lambda: Eli Habillo, the Unmoved Mover, and the Influence of Christian Philosophers

The explicit aim of Eli Habillo's 15th century short Commentary on Aristotle's Metaphysics, which is the only Hebrew commentary on the Metaphysics to include Book Lambda, is to provide for Hebrew reading Jews a taste of the richness of Scholastic literature on the topic and an account similar to that which the Christians received in their academies. In other works, Habillo disparages his Hebrew audience for their slavish adherence to Averroes and for not recognizing that there many other important commentators among the Christians, particularly Scotus and the Scotists. In his own Commentary on the Metaphysics Habillo gives a Scotist-style argument for the necessity of the Unmoved Mover as First Cause, which he works in to Aristotle's cosmological argument. Habillo criticizes many of those who theorized about the Metaphysics for rejecting the cosmological argument for the existence of God on the grounds that it is too weak, but says that it is nevertheless the strongest argument we (humans) have. Which metaphysical theorizers does he have in mind? Could the weakness Hebrew scholars perceived in the cosmological argument given in Metaphysics Lambda be the reason for its neglect by all other medieval Hebrew authors?
