The exercise of synchronic self-control is the way in which an actor can attempt to bring a desire into alignment with his better judgement at the moment and during the interval of time over which, but for the exercise of such self-control, the desire would become the actor’s preponderant desire, which the actor would then translate into an act contrary to his better judgment. The moral psychology of an actor who fails to achieve such self-control can be analyzed in two (...) ways. One way is meant to be consistent with compatibilist metaphysics; the other with libertarian metaphysics. The implications of these analyses for the criminal law are complicated, but perhaps the most important is this: the criminal law should in principle recognize a partial excuse for an actor who exercises synchronic self-control but who gives up his effort because he believes that he can no longer continue to resist. His effort to achieve self-control thus fails, and he ends up translating into action the very desire he set out to control. (shrink)

What is self-control and how does the concept of self-control relate to the notion of will-power? A widespread philosophical opinion has been that the notion of will-power does not add anything beyond what can be said using other motivational notions, such as strength of desire and intention. One exception is Richard Holton who, inspired by recent research in social psychology, has argued that will-power is a separate faculty needed for persisting in one's resolutions, what he calls 'strength of will'. However, (...) he distinguishes strength of will from self-control. In this paper I argue that will-power is essential also to a certain form of self-control. I support this claim by arguments showing that the traditional philosophical accounts of self-control run into difficulties because they pay insufficient attention to will-power as an independent source of motivation.
