 Causality plays an important role in medieval philosophical writing: the dominant genre of medieval academic writing was the commentary on an authoritative work, very often a work of Aristotle. Of the works of Aristotle thus commented on, the Physics plays a central role.  Other of Aristotle’s scientific works – On the Heavens and the Earth, On Generation and Corruption, and, of course, the Metaphysics – are also significant for the study of causation: so there is a rather daunting body of work to survey.
