 In Avicenna’s literal commentaries on the philosophical corpus, most of which are lost, metaphysics represents the section about which we are best informed by either Avicenna himself or his disciples (e.g., The Available and the Valid, Al-Ḥāṣil wa-l-maḥṣūl), or by the surviving portions (e.g., Book of the Fair Judgment, Kitāb al-Inṣāf). Judging from the extant fragments, conciseness and selectiveness appear to have been the stylistic and methodological hallmarks of Avicenna’s exegesis of the Metaphysics.
