 A key factor in the evaluation of the later impact of Avicenna’s metaphysics is the assessment of those of his works which mainly influenced later reflections on metaphysics, their ways of transmission, and their audience, since each of them, as we have seen, conveys a particular version and format of metaphysics. Among them, the metaphysical section of the Book of Pointers and Reminders has been singled out in scholarship because of the proliferation of independent commentaries on this work from the late XII until the early XVIII century by leading figures of Arabic-Islamic philosophy like Faḫr al-Dīn al-Rāzī (d. 1209) and Naṣīr al-Dīn al-Ṭūsī (d. 1274). Scholars attribute the success of Avicenna’s Pointers and Reminders to doctrinal, stylistic, and chronological factors. Doctrinally, Avicenna’s use of the essence-existence distinction to support the distinction between what is intrinsically necessary in something (like its essence) and what is extrinsically necessary in it (like its existence) was particularly obvious in the Pointers and Reminders. Stylistically, the work’s abbreviated and allusive style invites elaboration and commentary. Chronologically, this was Avicenna’s final comprehensive work and therefore could be presented as the definitive expression of his views. For these reasons, the Pointers and Reminders are currently considered to be the work of Avicenna privileged by subsequent Muslim philosophers (including the mutakallimūn).
