Abstract

This article offers an analysis, translation, and edition of a brief, recently uncovered Arabic text by the tenth-century CE Christian Aristotelian thinker Yaḥyā ibn ʿAdī. Ibn ʿAdī here takes issue with an argument for the existence of God, widely used in kalām. According to this argument, bodies cannot exist without being either in motion or at rest; motion and rest must begin; therefore all bodies and hence the universe as a whole must have begun. Ibn ʿAdī diagnoses various flaws in this reasoning, including a supposed part–whole fallacy. The analysis of the text shows how it fits into Ibn ʿAdī’s intellectual profile and the project of the Baghdad Aristotelian school.
