Abstract

The purpose of this dissertation is to present and defend a view regarding the freedom of human action which I call "Causationism," a view which incorporates some of the more fundamental commitments of traditional Determinism while allowing for the possibility of statistically regular actions or components of actions. Premise I of Causationism essentially maintains that all human actions are caused either by statistical regularities or deterministically. The inclusion of statistically regular events or components of actions in a causal account is based on an appeal to the Dretske-Snyder thesis of "Causal Irregularity." Premise II of Causationism is essentially identical to the Incompatibility Thesis of traditional Determinism. My theory then proceeds along traditional Deterministic lines, concluding with the claim that "No one is morally responsible for his or her actions." ;Premise I is defended by appeal to empirical evidence. It is then demonstrated that traditional Libertarian arguments intended to weaken the force of this evidence fail. ;In Chapter III, I consider objections to the Incompatibility Thesis. I argue that a hypothetical reading of "he could have done otherwise" not only fails to capture what we mean when we speak of an individual's "acting freely," but also that a hypothetical reading of this phrase fails to provide a sufficient condition for a morally relevant sense of "freedom." ;In Chapter IV, I argue, by appeal to the concept of "novelty" and to Davidson's Mind/Body Theory, that, contrary to the opinion of some philosophers, an event's being caused does not require that it be predictable or subsumable under statements of probability expectations. ;Chapter V addresses the claim that if all actions are caused, then no action can be rational. A variety of arguments are formulated to demonstrate that various versions of the "Determinist Dilemma" fail. ;Finally, in Chapter VI, I argue that adoption of Causationism does not destroy morality although the denial of moral responsibility significantly alters traditional morality and requires a reanalysis of certain basic ethical terms. I offer the required reanalyses and consider the ramifications of their adoption to ethical theory
