Taşköprizade on Complete Cause and Causal Priority A Critical Edition and Analysis of al-Nahal wa al-‘alal fi tahqiq aqsam al- ilal

Abstract

The post-classical traditions of kalām and philosophy witnessed an important innovation in the c sification of causes. Although the evolution of this classification’s terminology may be traced in various ways, its conceptual content cannot be found either in the classical period of Islamic philosophy or in the Greco-Hellenistic tradition. The classification in question divides causes into “complete” (tāmma) and “incomplete” (nāqiṣa). It emerged from attempts to address a number of significant questions arising from the interaction between Avicennan philosophy and Ashʿarī kalām. As a result of this search, the distinction between complete and incomplete causes was gradually articulated across the works of Athīr al-Dīn al-Abharī. It subsequently became the focal point of a problematic line of discussion in the correspondence between Najm al-Dīn al-Kātibī and Naṣīr al-Dīn al-Ṭūsī, giving rise to a three-century-long tradition of philosophical and theological debate, from the thirteenth century until the time of Taşköprīzāde. The latter’s treatise, which he entitled al-Nahal wa al-ʿalal fī taḥqīq aqsām al-ʿilal (“Quenching Draughts for the Investigation of the Divisions of Causes”), presents this debate as a lively arena of disputation, with Taşköprizāde himself acting as its arbiter. In doing so, the treatise renders visible within a single work a set of positions that had previously appeared only in dispersed form as part of broader writings. The present study offers a critical edition of Taşköprizāde’s treatise al-Nahal wa al-ʿalal fī taḥqīq aqsām al-ʿilal, in which he addresses the question of the complete cause and the problem of causal priority. The edition is based on two manuscriptsone in the author’s own hand and the other copied by his son—and is accompanied by an analysis that seeks to illuminate the treatise’s problematic background.
