Proving God's Existence? A Reassessment of al-Rāzī’s Arguments for the Existence of the Creator

Arguments for God's existence, it has often been argued in the secondary academic literature, form an essential part of classical Islamic theology (ʿilm al-kalām) and philosophy (falsafa). In the past decades, numerous scholars have dealt with what could be termed the Islamic discourse on arguments for God's existence, and have commonly analysed these arguments making recourse to Immanuel Kant's (1724–1804) categorisation of such arguments as cosmological, teleological, or ontological. The great Ashʿarī theologian Fakhr al-Dīn al-Rāzī (d. 606/1210) is, unsurprisingly, seen as no exception to this: he, too, has been regarded as a participant in the aforementioned discourse, and in several of his major kalām works he introduces four methods to ‘prove the existence of the creator’. In this article, I will, however, argue that al-Rāzī had no concern for proving God's existence; the arguments in his kalām works, which, in the secondary academic literature, have been described as seeking to prove that God exists, it shall be suggested, serve a different purpose. This shall become clear when al-Rāzī’s commentary on the Qur'an, al-Tafsīr al-kabīr, is taken into account. Previous studies of al-Rāzī’s (alleged) arguments for God's existence have only focused on his kalām works proper, however, in the Tafsīr al-Rāzī not only presents the very same four kalām methods to ‘prove the existence of the creator’ and stresses that they originate in Qur'anic forms of argumentation, but he also places them in a thematic context which, in his theological works, is oftentimes lacking. This article therefore clarifies the objective underlying al-Rāzī’s arguments for the existence of the creator and explains their significance in his broader theological thought.
