Abstract

Compatibilists believe that moral responsibility and causal determinism are compatible. Incompatibilists, on the other hand, believe that if causal determinism is true, then no agent is morally responsible for her actions. The principle of alternative possibilities, or PAP, claims that an agent is morally responsible for an action only if she could have done other than the action in question. In a landmark article, Harry Frankfurt attempts to advance the compatibilist's position by arguing that the principle of alternative possibilities is false. To demonstrate the falsity of PAP, Frankfurt describes a scenario in which an agent appears to have no alternative possibilities yet is still morally responsible. This scenario and others like it have come to be called Frankfurt-style counterexamples, or FSCs. ;One prominent incompatibilist response to FSCs is to argue that, despite Frankfurt's argument, FSCs do not in fact undermine PAP. Many incompatibilists argue that, contrary to Frankfurt's claim, the agent in an FSC still has relevant alternative possibilities. According to some of these incompatibilists, the actual and alternate sequences of an FSC contain numerically distinct events which can serve as the relevant alternatives. Of course, such a response depends upon one's metaphysic of events and their individuation. In this dissertation, I explore the implications of various accounts of event-individuation for the debate surrounding the success of FSCs and their purported repudiation of PAP. I survey the dominant theories of events and their individuation and raise a number of objections to these extant theories. I then develop a property-exemplification view of events and their individuation, situated within a larger Aristotelian metaphysic that avoids these criticisms. I then examine the effect this account has for the debate surrounding FSCs
