One striking oddity about Democritus and Epicurus is that, even though Epicurus' theory of perception is largely the same as that of Democritus, Democritus and his followers draw skeptical conclusions from this theory of perception, whereas Epicurus declares that all perceptions are true or real. I believe that the dispute between Democritus and Epicurus stems from a question over what sort of ontological status should be assigned to sensible qualities. In this paper, I address three questions: 1) Why were Democritus (...) and his followers skeptical? 2) How did Epicurus modify Democritus' metaphysics in order to avoid these skeptical conclusions? and 3) How successful was he? -/- 1) I argue that Democritus allows only the intrinsic properties of atoms into his ontology, and then runs into skeptical difficulties because of the relativity of perception. 2) I propose that Epicurus modifies Democritus' ontology by allowing dispositional and relational properties as real properties of bodies. Sensible qualities are conceptualized as dispositional properties of bodies to cause certain experiences in percipients. 3) I argue that Epicurus does not run into the same problems as Democritus. Finally, I consider how my interpretation of Epicurus' ontology helps to make sense of his claim that all perceptions are alethes--'true' or 'real.'. (shrink)

Appeals to nature are ubiquitous in Epicurean ethics and politics. The foundation of Epicurean ethics is its claim that pleasure is the sole intrinsic good and pain the sole intrinsic evil, and this is supposedly shown by the behavior of infants who have not yet been corrupted, "when nature's judgement is pure and whole." Central to their recommendations about how to attain pleasure is their division between types of desires: the natural and necessary ones, the natural but non-necessary ones, and (...) the vain and empty ones. Elsewhere, the Epicureans talk about the "natural goods" of political power and fame, and they contrast "natural wealth" with wealth as "defined by empty opinion." Finally, in their politics, Epicurus claims that the "the justice of nature is a pledge of reciprocal usefulness, [i.e.,] neither to harm one another nor to be harmed." This paper explores two questions regarding these various appeals to nature. The first is: what is it for these things to be natural, i.e., what notion of "natural" or "nature" is at play here? (Furthermore, is there a single notion being used across these appeals, and if not, how are they related?) The second is: what normative work does a thing's being natural do? That is, what reason, if any, does a desire's being natural give me for pursuing the object of that desire and trying to fulfill that desire, as opposed to not doing so and trying to eliminate it, and similarly for the other appeals to nature?

Socrates has an implicit argument for his afterlife story that concludes the Gorgias, with two key premises. One is at 527a–c, where he summarizes the ethical position he has been arguing for through most of the dialogue, regarding the intrinsic goodness of justice, the intrinsic badness of injustice, and the desirability of rehabilitative punishments. The second occurs at 507e–508a, where Socrates asserts that the universe is held together by justice. This argument explains why Socrates regards his story as a logos, (...) not merely a muthos. It also helps us understand the nature of the rewards and punishments in his story. (shrink)

Unlike mainstream Cyrenaics, the Annicereans deny that friendship is chosen only because of its usefulness. Instead, the wise person cares for her friend and endures pains for him because of her goodwill and love. Nonetheless, the Annicereans maintain that your own pleasure is the telos and that a friend’s happiness isn’t intrinsically choiceworthy. Their position appears internally inconsistent or to attribute doublethink to the wise person. But we can avoid these problems. We have good textual grounds to attribute to the (...) Annicereans a doctrine of “non-hedonic habits,” which allows them to abandon psychological hedonism while still maintaining hedonism regarding well-being. (shrink)
