Abstract

Did classical kalām debates about how thing and existent relate to each other pave the way for Avicenna's distinction between essence and existence? There are some indications that the concept of thingness may have played a bridging role between the mutakallimūn's discussions and those of Avicenna. Nevertheless, Avicenna's appeals to thingness occur most densely in passages devoted to analyzing the relationship between efficient and final causes, an entirely Aristotelian topic. A philological question arises: should these passages be emended to read causality in place of thingness? I argue that the balance of evidence compels us to retain thingness. For Avicenna, thingness is the respect in which the final cause is prior to the efficient cause ; existence, by contrast, is the respect in which the efficient cause is prior to the final cause. In fact, over the course of Avicenna's career a progression from the kalām problematic of šay' v. maw[gcaron]ūd to his own problematic of māhiyya v. wu[gcaron]ūd can be detected in his discussions of efficient and final causation.
