Fakhr al-Dīn al-Rāzī on the Existence and Nature of the Jinn

This article reconstructs Fakhr al-Dīn al-Rāzī’s (d. 1210) systematic treatment of the jinn in his Great Exegesis (al-Tafsīr al-Kabīr) and his summa The Sublime Objectives in Metaphysics (al-Maṭālib al-ʿĀliya min al-ʿIlm al-Ilāhī). In these works, al-Rāzī treats the jinn not as a marginal curiosity but as a test case for probing core metaphysical categories such as substance, embodiment, and divine action. His analysis unfolds through a sequence of guiding questions. Do the jinn exist at all? If not, we arrive at (1) the Denialist View. If they do exist, they must be either immaterial or material. The first yields (2) the Immaterialist View. The second raises the further question of whether bodies differ in essence or share a single essence. If they differ, we arrive at (3) the Non-Essentialist Corporealist View. Notably, these first three views are associated, in different ways, with various figures in the falsafa tradition. If they share a single essence, this produces the Essentialist Corporealist position, which then divides according to whether bodily structure is metaphysically necessary for life and agency. If not necessary, this produces (4) the Essentialist Corporealist—Structural Independence View, associated with the Ashʿarīs. If necessary, it leads to (5) the Essentialist Corporealist—Structural Dependence View, associated with the Muʿtazilīs. Al-Rāzī rejects (1) and (5), but he leaves (2), (3), and (4) as live possibilities. While he shows greater sympathy for (4), his broader purpose is not to settle the matter but to map the full range of theological and philosophical options. Al-Rāzī’s comprehensive exposition reflects the wider dialectic between falsafa, Ashʿarī theology, and Muʿtazilī theology, showcasing a sophisticated willingness to engage and entertain multiple metaphysical possibilities side by side. The result is an exercise in systematic metaphysics, where the question of the jinn, as liminal beings, becomes a means for interrogating broader ontological commitments in Islamic theology and philosophy.
