Abstract

My dissertation is concerned with Epicurus' attempt to reconcile libertarianism and atomism. I begin by offering my solution to 'the problem of the swerve,' arguing that Lucretius is claiming that swerves cause volitions 'from the bottom up' and that the attempts of scholars to construct a better position for Epicurus to have held were doomed to fail, since this is the only position open to the libertarian atomist. ;I also examine the swerve's role in cosmogony, arguing that 'the cosmogonic argument' for the swerve is an afterthought, 'the libertarian argument' being Epicurus' chief argument for the swerve. ;I discuss the physics of the swerve as a minimal, oblique deviation of an atom from its course. And I explore its implications: atoms move at a speed greater than one minimal unit of distance per minimal unit of time, and there are no minimal units of space. ;Returning to the question of the swerve's role in action, I argue that a typical action involves a series of volitions each caused by a plurality of swerves by atoms of the mind's 'fourth nature.' And I argue that one's power to move at will is directly sensed, though also known through one's innate $\pi\rho\acute{o}\lambda\eta\psi\iota\varsigma$ of one's freedom. ;In the second half of my dissertation, I turn to the question of responsibility. I examine Epicurus' remarks about 'what is due to us' . I examine Epicurus' argument that Democriteans are self-refuting in espousing determinism and 'eliminative materialism.' I explain that Epicurus rejects only Democritus' ontology, not his epistemology . I examine Epicurus' discussion in On Nature of our 'notion of responsibility' , our responsibility as $\alpha\pi o\gamma\varepsilon\gamma\varepsilon\nu\nu\eta\mu\acute \varepsilon\nu\alpha$ , and our responsibility for our thoughts of the $\tau\acute\varepsilon\lambda o\varsigma$ and 'the criterion' . I explain what Epicurus means by the $\tau\acute\varepsilon\lambda o\varsigma$: pleasure, "katastematic" and "kinetic" . And finally, I argue that Epicurus fails to meet the challenge of 'psychological determinism'.
