 As for Albalag, his account of celestial motion consistently attributes celestial motion to the efficient, formal and final causation of separate intellects. Relaying on Averroes, while giving the credit to Aristotle, Albalag argues that the three modes of causation are one in the divine realm (cf. Averroes Commentary on Metaphysics: 149). While separate intellects are themselves invariable, they produce motion in the spheres in three different manners (Tiqqun n.64: 92).
