In this course we shall investigate several aspects of the metaphysics of free will, time, and causation. First, we shall discuss the question about the nature of efficient causes of free actions, i.e. whether they are events or agents. Second, we shall consider arguments for and against the compatibility of free will and physical determinism. Third, we shall investigate how temporal, causal and counterfactual asymmetries are related to our free agency. And finally, we shall discuss the possibility of affecting the past by our actions.
