Causation is now commonly supposed to involve a succession that instantiates some law-like regularity. Efficient Causation: A History examines how our modern notion developed from a very different understanding of efficient causation. This volume begins with Aristotle’s initial conception of efficient causation, and then considers the transformations and reconsiderations of this conception in late antiquity, medieval and modern philosophy, ending with contemporary accounts of causation. It includes four short Reflections that explore the significance of the concept for literature, the history of music, the history of science, and contemporary art theory.
