Moreover, ‘Abd al-Latif summarizes in the contents, but not in the order, a selection of twenty propositions of Proclus (1–3, 5, 62, 86, 15–17, 21, 54, 76, 78, 91, 79, 80, 167, and 72–74: see Zimmermann 1986), four quaestiones of Alexander of Aphrodisias (Van Ess 1966; Fazzo &amp; Wiesner 1993) and the adaptation of John Philoponus’ De aeternitate mundi contra Proclum IX,8 and IX,11 (Hasnawi 1994), entitled What Alexander of Aphrodisias Extracted from the Book of Aristotle Called Theology, Namely the Doctrine of Divine Sovereignty (Endress 1973). In doing that ‘Abd al-Latif sets for himself three objectives. In the first place, he wants to stress the crucial aspects of the doctrine of the First Cause understood as One, presented in the previous chapters. In the second place, he discusses the relationship between the One and the many, and, not by chance, he does so after a series of chapters (16–20) devoted to the relationship between the First Cause and the world. As for these two objectives, he stresses the basic features of the First Cause: it is One and it gives unity to that which is multiple; it is One in itself and the True One without composition; it is the cause of all that which is multiple in that, although it is by essence One, its causal action propagates in a multiplicity of effects; it is above eternity and time; it is life that does not end, light that does not extinguish, it is Pure Being, it is the first agent, it is ineffable and nothing can be properly predicated of it, it is unknowable, the apex of the hierarchy of being which is composed of the intellect, intelligible realities, the Soul, the souls, and, finally, the corporeal realities of nature. Then he turns to the providence of the First Cause with regard to its effects: this providence exists, is mediated by the spheres and preserves the species on earth. The divine power acts upon the sublunary world by contact, and, starting from the first sphere of fire, the divine power is in matter according to the receptivity of the various matters.
