Abstract
Abstract: The first purpose of this article is to present a new theory of libertarian free will—the boundary theory of libertarian free will—which provides a new framework by means of employing boundaries as a “conceptual scheme” for understanding libertarian free will. This theory consists of two parts. One part suggests that the agent’s will should be viewed as the intermediate boundary between an agent’s reasons and his alternative choices. The second part is a model where the agent’s will is a faculty that solely operates by permitting or resisting reasons (that are potential causes) to become actual causes for the agent’s choices. The second purpose of the paper is to argue that the boundary theory of libertarian free will has several advantages, the most important of which are: (a) it defeats the charge that libertarian free will is a mystery; (b) it defeats the standard objections against the compatibility of libertarian free will and indeterminism (that is, the luck argument, the roll-back argument, the difference argument, the assimilation argument, etc.); and (c) it is simultaneously an argument for indeterminism as such (that is, that determinism is false).
