Anaxarchus accompanied Pyrrho on Alexander the Great’s expedition to India and was known as “the Happy Man” because of his impassivity and contentment. Our sources on his philosophy are limited and largely consist of anecdotes about his interactions with Pyrrho and Alexander, but they allow us to reconstruct a distinctive ethical position. This position overlaps with several disparate ethical traditions, but is not merely a hodge-podge; it hangs together as a unified whole. Like Pyrrho, Anaxarchus asserts that things are indifferent in value and that realizing this indifference leads to contentment. But this doctrine of indifference is rooted in Democritean atomism. And in his pursuit of pleasure and dismissiveness of conventional standards of what is just, noble, and pious, Anaxarchus is closer to fifth-century thinkers such as Aristippus, Antiphon, and Critias.

Unlike mainstream Cyrenaics, the Annicereans deny that friendship is chosen only because of its usefulness: 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 is not intrinsically choiceworthy. I argue that this is to be explained by evidence for an Annicerean doctrine of ‘non-hedonic habits’, which allows them to abandon psychological hedonism while still maintaining hedonism regarding well-being.

I begin by considering an argument for why there would not be justice in a community of wise Epicureans: justice only exists where there is an agreement "neither to harm nor be harmed," and such an agreement would be superfluous in a community of wise Epicureans, since they would have no vain desires which would lead them to wish to harm one another. I argue that, if the 'justice contract' prohibits only direct harm of one person by another, then it would be superfluous among Epicureans. However, Lucretius and Hermarchus make it clear that people enter into communities in order to protect themselves from harm from animals and from starvation, and that regulations needed in order for the community to protect the members from these dangers also fall under the purview of justice. Given this more expansive reading of the content of the 'justice contract,' such agreements would be needed in any community, even ones which had only wise Epicureans as members.

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.

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?

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.'

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.

What is distinctive about Lucretius’s version of Epicureanism? The answer might appear to be “nothing,” for two reasons. First, Epicureanism in general is doctrinally conservative, with followers of Epicurus claiming to follow his authority. Second, Lucretius claims to be merely transmitting the arguments of his beloved master Epicurus in a pleasing manner. I argue that these considerations do not prevent De Rerum Natura from presenting a distinct version of Epicureanism. Its arguments in physics are almost certainly drawn from Epicurus himself. But in the examples Lucretius uses to illustrate these arguments, as well as in his descriptions of things like the fear of death and the formation of society, Lucretius delivers unexpected insights into human psychology, ones not clearly present in the other sources we have on Epicureanism. Furthermore, the way in which Lucretius presents his arguments can rightly be considered original philosophically and not just poetically.

A fairly long (~15,000 word) overview of ancient theories of freedom and determinism. It covers the supposed threat of causal determinism to "free will," i.e., the sort of control we need to have in order to be rightly held responsible for our actions. But it also discusses fatalistic arguments that proceed from the Principle of Bivalence, what responsibility we have for our own characters, and god and fate. Philosophers discussed include Aristotle, Epicurus, the Stoics, Carneades, Alexander of Aphrodisias, and Plotinus. Plato is mentioned in passing a few times in connection with other philosophers.

Epicurus thought that the conventional values of Greek society—in particular, its celebration of luxury and wealth—often led people astray. It is by rejecting these values, reducing our desires, and leading a moderately ascetic life that we can attain happiness. But Epicurus’ message is also pertinent for those of us in modern Western culture, with an economy based on constant consumption and an advertising industry that molds us to serve that economy by enlarging our desires. This paper begins with an outline of some of the basic tenets of Epicurean ethics, followed by an explanation of how these tenets lead to an Epicurean diagnosis of what ails modern consumers and of the cure they would propose. The paper closes with a consideration of recent psychological research in well-being and how it supports the Epicurean position.

The first part of this paper looks into the question of Lucretius’ philosophical sources and whether he draws almost exclusively from Epicurus himself or also from later Epicurean texts. I argue that such debates are inconclusive and likely will remain so, even if additional Epicurean texts are discovered, and that even if we were able to ascertain Lucretius’ philosophical sources, doing so would add little to our understanding of the De Rerum Natura. The second part of the paper turns to a consideration of what Lucretius does with his philosophical sources. The arguments within the De Rerum Natura are not original. Nonetheless, the way Lucretius presents these arguments establishes him as a distinctive philosopher. Lucretius deploys non-argumentative methods of persuasion such as appealing to emotions, redeploying powerful cultural tropes, and ridicule. These methods of persuasion do not undercut or displace reasoned argumentation. Instead, they complement it. Lucretius’ use of these methods is rooted in his understanding of human psychology, that we have been culturally conditioned to have empty desires, false beliefs, and destructive emotions, ones that are often subconscious. Effective persuasion must take into account the biases, stereotypes, and other psychological factors that hinder people from accepting Epicurus’ healing gospel.

Because of the "swerve," it is often thought that Epicurus is the first philosopher to offer a libertarian solution to the so-called "problem of free will." I argue that Epicurus is not a libertarian. The rest of Epicurus' philosophy is incompatible with libertarianism. Epicurus is a materialist and a reductionist. Only atoms and void exist per se, and all events are explicable in terms of the mechanical interaction of atoms. This reductionism holds in his philosophy of mind also: the mind is identified with a group of atoms, and mental events are identified with atomic events. It would be difficult to accommodate a libertarian version of agent-causation with such views. I also engage in a close reading of On Nature 25 and argue that it does not support David Sedley's contention that Epicurus is here asserting the causal independence of the self from the atoms. ;Using Cicero's De Fato as my main source, I maintain that Epicurus is an incompatibilist of a certain sort, but that his concerns differ significantly from those of modern libertarians. He is not trying to show that the agent "could have done otherwise" as a necessary condition of moral responsibility. Instead, he is trying to solve the problem Diodorus Cronus poses in the "Master Argument" and Aristotle addresses in De Interpretatione 9, the seeming incompatibility of logical determinism and deliberation: e.g., if it has always been true that there will be a sea-battle tomonrow, how can my deliberating about it now make a difference? Epicurus' response to this problem is similar to Aristotle's: he undercuts the determinist's arguments by denying that all statements about the future presently have a truth-value. The swerve is his means of doing so, since Epicurus thinks that causal determinism and logical determinism are inter-entailing. Given the swerve, there do not presently exist sufficient conditions for the truth of all statements about the future. The swerve thus preserves contingency in the universe, which is a precondition of effective deliberation, but it plays no direct role in Epicurus' action-theory

This paper focuses on two questions: (I) why do the Cyrenaics deny that we can gain knowledge concerning "external things," and (II) how wide-ranging is this denial? On the first question, I argue that the Cyrenaics are skeptical because of their contrast between the indubitable grasp we have of own affections, versus the inaccessibility of external things that cause these affections. Furthermore, this inaccessibility is due to our cognitive and perceptual limitations--it is an epistemological doctrine rooted in their psychology--and not (pace Zilioli) due to any metaphysical theses regarding the external world. On the second question, I argue (pace Tsouna and Warren) that the scope of the Cyrenaics' skepticism is quite wide. Our reports on the Cyrenaics are inconsistent, but the most charitable and plausible reading results in attributing to the Cyrenaics skepticism not merely about the properties of external things (e.g., that the fire that warms me is really hot) of also of their nature and identity (e.g., that the object that warms me is a fire). However, it does not extend to skepticism regarding the existence of an external world.
