These observations regarding Hume and the doctrine of voluntarism are of considerable relevance to the contemporary ethical debate as it concerns what Bernard Williams has described as “the morality system” (Williams, 1985: Chp. 10). Although Williams’ (hostile) account of the morality system is multifaceted and defies easy summary, its core features are clear enough. The concept that Williams identifies as fundamental to the morality system is its special notion of obligation. Flowing from this special concept of obligation are the related concepts of right and wrong, blame and voluntariness. When agents voluntarily violate their obligations they do wrong and are liable to blame and some measure of retribution. To this extent the morality system, so conceived, involves what Williams calls “the blame system”, which focuses on particular acts (Williams, 1985: 194). According to Williams there is pressure within the blame system “to require a voluntariness that will be total and will cut through character and psychological or social determinism, and allocate blame and responsibility on the ultimately fair basis of the agent’s own contribution, no more and no less” (Williams, 1985: 194).
