Experience is the cornerstone of Epicurean philosophy and nowhere is this more apparent than in the Epicurean views about the nature, formation, and application of concepts. ‘The Epicureans on Preconceptions and Other Concepts’ by Gábor Betegh and Voula Tsouna aims to piece together the approach to concepts suggested by Epicurus and his early associates, trace its historical development over a period of approximately five centuries, compare it with competing views, and highlight the philosophical value of the Epicurean account on that subject. It is not clear whether, properly speaking, the Epicureans can be claimed to have a theory about concepts. However, an in-depth discussion of the relevant questions will show that the Epicureans advance a coherent if elliptical explanation of the nature and formation of concepts and of their epistemological and ethical role. Also, the chapter establishes that, although the core of the Epicurean account remains fundamentally unaffected, there are shifts of emphasis and new developments marking the passage from one generation of Epicureans to another and from one era to the next.

This chapter sums up the main argument of the book and offers a brief overview of the reception of the Epicurean theory of justice.

This chapter provides an account of the agreements that lead to the creation of justice on the Epicurean view. In doing so, the three sections of the chapter complete the argument of Chapter 1 by focusing on the textual evidence in Epicurus and later Epicurean authors. The first section elaborates on the claim that the Epicureans defend a middle position in the nomos-phusis debate. The second section describes in more detail the content and function of agreements in Epicureanism. And the third section deals with the topic of who can make agreements on the Epicurean view, including the question of whether there can be agreements with nonhuman animals.

This chapter discusses the nomos-phusis debate of the fifth and fourth century BCE and introduces the book’s main argument: that the Epicureans defend a sophisticated middle position (vis-à-vis Plato and Aristotle, on the one hand, and some sophists, on the other) in this debate when it comes to justice. On the Epicurean view, justice is neither fully natural nor conventional; there is a robust virtue of justice and it is always better to be just than to be unjust, but it is not always better to obey the laws.

Modern discussions of Epicureanism often use the descriptions “legal positivism” and “natural law theory” without providing clear definitions of what is meant by these terms. This chapter remedies this deficiency by characterizing the Epicurean theory of justice and law from the perspective of contemporary philosophy of law. The first section develops a clear conceptual framework by distinguishing between different theses that characterize a view as leaning more toward legal positivism or natural law theory. The second section then tests Epicurean theory against these theses, concluding that even if the Epicurean account has some legal positivist leanings, it is overall closer to a kind of natural law theory.

This chapter argues that while being just is of supreme importance in Epicureanism, obeying the law in all cases is not: the Epicureans allow that laws whose adherence is not useful and whose violation does not entail negative consequences may be violated. In arguing for this claim, the chapter discusses a question that Epicurus posed himself in a work that is no longer extant, namely, whether a sage, an ideal agent, would violate a law, knowing he will escape detection. The chapter provides a detailed suggestion on how to understand Epicurus’ pronouncement, discusses alternative readings that have been advanced by other scholars, and addresses some objections that one could raise against the suggestion of the chapter.

This chapter shows that although the Epicureans claim that justice comes to be by agreements, they also argue for the existence of a robust virtue of justice. The first section of the chapter gives a general overview of the Epicurean theory of the virtues, while the second section examines in detail the passages in which Epicurean authors discuss the virtue of justice. The third and last section of the chapter turns to the precise relationship between contractual and aretaic justice on the Epicurean view. It argues that the former is a precondition for latter, as contractual justice specifies the content of aretaic justice and provides the developmental basis for aretaic justice to emerge.

This chapter argues that the Epicureans defend a kind of ethical naturalism. The first section of the chapter, focusing on ontology, shows that for the Epicureans justice is conceived of as an accidental property (sumptōma/eventum) and is of the same general sort as the properties that are investigated in science. The second section, turning to moral epistemology, argues that, on the Epicurean view, what is just is directly perceived, showing that the investigation of ethical properties happens in the same general way as investigation in the sciences on the Epicurean view.

This chapter relates how justice comes to be on the Epicurean view by examining in detail the Epicurean account preserved in Lucretius’ On the Nature of Things V. In doing so, the chapter shows that the Epicureans are defenders of a kind of social contract theory and so side with defenders of nomos in the nomos-phusis debate. Nevertheless, their conception of nomos is importantly constrained by phusis. Furthermore, the chapter also argues against those readers who have characterized the Epicurean account of the social contract as Hobbesian. If the Epicurean account is to be assimilated to a modern view, the ideas of Jean-Jacques Rousseau are a much better fit.

This chapter investigates ancient accounts of women Epicureans and considers how critics of Epicureanism attempted to undermine hedonism by sexualizing their accounts of the school’s women. The misogyny directed at women Epicureans was noteworthy insofar as its primary goal seems not to have been to undermine the women themselves but rather to undermine the school’s main ethical tenets; in other words, anti-hedonists used misogyny as a tool for philosophical criticism. The chapter aims to show that, despite the scarcity of extant philosophical works by Epicurean women, there is still much to be gained from studying the extant accounts of their activities and relationships: we stand to deepen our understanding of the place of women in the school, particularly our knowledge of how they were viewed by other members, as well as our understanding of the polemical tactics employed by ancient critics of Epicurean hedonism.

Chapter 4 is an in-depth study of Seneca’s handling of Epicurean material throughout his philosophical writings. It is primarily because of his interest in Epicurus that Seneca in the past was sometimes labeled an “eclectic” philosopher. In reality, he is implacably hostile to the philosophical doctrines of Epicureanism, from atomism and the idleness of the gods to the pleasure principle and the utilitarian basis of friendship and justice. In the Letters on Ethics, however, he signals receptivity to some of Epicurus’s therapeutic strategies, where he finds them psychologically plausible. These strategies include the use of maxims in teaching and certain arguments against the fear of death and of bodily pain. Seneca is able to adapt these to his own purposes without sacrificing his own Stoic principles.

This paper reexamines the intertextual connection between Lucretius and Ennius from a multi-medial angle. Ennius’ tragedies were regularly revived in the late Republic, and selections from his epic Annals appear to have been recited in public contexts as well. These performances seem to have stood in a relationship of reciprocal influence with wall paintings, as stagings inspired painters, and their artwork influenced actors in turn. Accordingly, Lucretius treats Ennius’ works as particularly influential expressions of a harmful philosophy that threatens Epicurean ataraxia in a variety of contexts. Analyzing familiar points of contact between the two authors in Book One of On the Nature of Things and highlighting a number of as-yet undiscussed allusions, I argue that Lucretius equips his readers with the tools to challenge Ennius in all three of the relevant media, be it on the page, on the stage, or in images.

This paper offers a provocative re-reading of the passage about the sizes of the sun, moon, and stars late in Lucretius’ De Rerum Natura (5.564-613). Attention to not only details of argumentation but also shades of meaning and contorted syntax shows a more complex, ambiguous presentation than generally acknowledged. This paper suggests that Lucretius' narrator—rather than merely parroting wrong, ridiculed doctrines—pulls student-readers into the process of inquiry. It becomes the didactic audience’s task to receive data from sense-perception and use lessons learned earlier in the poem in making correct judgments based upon that data. In Epicurean and Lucretian accounts of reality, the senses themselves are infallible; so the Lucretius-ego’s assertion that the sun as big as perceived by our senses must also be infallible. But our interpretation of what that assertion entails about the sun’s actual size is a matter of judgment, and thus fallible and uncertain indeed.

This book examines the role and influence of Greek philosophy in the final days of the Roman republic. It focuses primarily (although not exclusively) on the works and views Cicero, premier politician and Roman philosopher of the day, and Lucretius, foremost among the representatives and supporters of Epicureanism at the time.

Lucian’s satires on Peregrinus of Parium and Alexander of Abonoteichos illustrate the growing importance of religion in contests over cultural authority in the second century CE. Prophecy in particular plays a central role in the establishment of Peregrinus’s and Alexander’s authority, and in the satirist’s reframing of these men as charlatans. In fabricating his own prophecies, and thus competing with these would-be holy men at their own game (however satirically), Lucian threatens to reveal himself as just another fame-seeker within the agonistic display culture of the high Roman empire.
