Presentation 2: MU Team 2 Bennett, Paffenroth, Jaworski: Avicenna on Divine Being in his Metaphysics. Class Readings: For understanding Avicenna’s metaphysics it is important to see how he begins with the first four chapters of Book 1 (1.1-4, Marmura translation). But for our limited time these are the major texts on which to focus for our topic of Divine Being: 1.5 on the ideas of “existent,” “thing,” and “necessary.” Note 1.5 (24) on the necessary; 1.6-7 begins his account of the Necessary Existent; the discussions found in Books 8 and 9 are key for our topic. For secondary sources, see Olga Lizzini’s “Ibn Sina’s Metaphysics” in the Stanford Encyclopedia of Philosophy and Amos Bertolacci’s “Arabic and Islamic Metaphysics” also n the Stanford Encyclopedia of Philosophy. Also for an overview of this thinker’s work, see D. Gutas, “Ibn Sina [Avicenna],” as well n the Stanford Encyclopedia of Philosophy. MU Team 2 will go deeper into the texts and secondary literature.
