My research rethinks the central aspects of Aristotle's philosophy of action. Aristotle worked on many topics that contemporary philosophers working on action are interested in although he did so within a different philosophical framework and historical context. While recent scholarship has done much to show the unique features of Aristotle's philosophy, a comprehensive study of his philosophy of action is missing. My research aims to fill this gap by systematically working out his views on action by studying his natural philosophy, metaphysics, psychology, and ethics. In my DPhil dissertation I discuss some of the basic features of Aristotle's views on the ontology, causation, and explanation of change and action. I plan to expand on this research to include Aristotle's psychology and ethics, and to consider underexplored themes in Aristotle-scholarship, like habitual actions and social agency.

Aristotle on Action and Agency

In my dissertation I develop Aristotle's ontology of action, and his views on the causation and explanation of action. I argue that actions are hylomorphic processes: continuous entities which have both formal and material features. This sets Aristotle's views apart from certain contemporary views that hold that actions are events of bodily motion, caused by mental events or events in the agent's body.

I argue that Aristotle did not accept a notion of causation where causes and effects are distinct events. The entities in the causal relation are substances of some kind; and the agent’s action and the affection the patient undergoes through the agent's action, are two different ways of describing one and the same process. Since Aristotle's notion of agency includes non-living substances, I also discuss how he distinguishes between this broad notion of agency and the agency of living substances.


I plan to complement my dissertation by researching two related themes in Aristotle's philosophy. The first is to how cognitive activities like perception, reason, and desire relate to each other, on the one hand, and to bodily motion and action, on the other. This complements our understanding of actions as goal-directed, hylomorphic, processes. The second theme is Aristotle's views on responsibility for action. This complements our understanding of Aristotle's views on human agency, which gives us a better understanding of his philosophy of action in general.
