Did Epicurus Discover the Free-Will Problem?
This chapter shows, through painstaking analysis of the extant texts (Epicurus, Lucretius, Diogenes Laertius, et al.), that there is no evidence that Epicurus dealt with the kind of free-will problem with which he is traditionally associated, i.e. that he discussed free choice or moral responsibility grounded on free choice, or that the ‘swerve’ was involved in decision processes. Rather, for Epicurus, actions are fully determined by the agent’s mental disposition at the outset of the action. Moral responsibility presupposes not free choice but that the person is unforced and causally responsible for the action. This requires the agent’s ability to influence causally, more specifically on the basis of their beliefs, the development of their behavioural dispositions. The ‘swerve’ was intended to explain the non-necessity of agency without undermining Epicurus’ atomistic explanation of the order in the universe, viz. by making the mental dispositions of adults non-necessary.
