In his version of atomism, Lucretius made explicit reference to the concept of an intrinsic declination of the atom, the atomic swerve (clinamen in Latin), stressing that the time and space of the infinitesimal atomic vibration is uncertain. The topic of this article is the Epicurean and Lucretian arguments in favour of the swerve. Our exposition of the Lucretian model of the atomic clinamen will present and elucidate the respective considerations on the alleged role of the swerve in the generation (...) of free-action.

Epicurean ethics has been subject to withering ancient and contemporary criticism for the supposed irreconcilability of Epicurus’s emphatic endorsement of friendship and his equally clear and striking ethical egoism. Recently, Matthew Evans (2004) has suggested that the key to a plausible Epicurean response to these criticisms must begin by understanding why friendship is valuable for Epicurus. In the first section of this paper I develop Evans’ suggestion further. I argue that a shared conception of the human telos and of what (...) is required to attain it structures the confidence that characterizes friendship. In the second part of the paper I return to two contemporary criticisms of Epicurean friendship. The first criticism focuses on the problem of free riders. The second criticism points to a seeming inconsistency in Epicurean doctrine. I suggest that both criticisms can be adequately addressed once we understand Epicurean friendship in greater depth.

Although the Epicurean ethical system is fundamentally egoistic and hedonistic, it attributes a surprisingly significant role to friendship. Even so, I argue that traditional discussions of Epicurean friendship fail to adequately account for the value of individual friends. In this thesis I present an amended notion of Epicurean friendship that better accounts for all of the pleasure friends afford. However, the success of my project requires rejecting an Epicurean ethical principle. Because of this, I explore textual evidence both in favor (...) and against the amended notion I propose and the problematic ethical principle. After arguing against the problematic ethical principle and dispelling additional objections to my project, I conclude that Epicureans should endorse the amended notion of friendship I have developed.

While the aim of the present paper is to analyze Olympiodorus’ commentary to Plato’s Phaedo, particular attention will be paid here to the role of hēdonē. The first part of the text presents the four conceptions of the pleasure that can be found in Plato’s dialogue. Although pleasure does not play the most prominent role either in the Plato’s dialogue or in the Neoplatonic commentary, Olympiodorus’ attitude to this issue reveals an important change and difference between the philosophical views of (...) Plato and those of Olympiodorus. The latter does not seem to discern the possibility that pleasure can have its spiritual dimension. Thus, the experience of hēdonē is reduced solely to the sphere of the senses and even in this area its role needs to be minimized: in this form it has to be carefully measured and controled. Furthermore, Olympiodorus does not see that so-called hedonistic calculus: whilst it is not strictly speaking connected with virtuous actions, it still can have some significance for the the philosopher’s life.

Sextus Empiricus ascribes to Epicurus a curious account of truth and falsehood, according to which these characteristics belong to things in the world about which one speaks, not to what one says about them. I propose an interpretation that takes this account seriously and explains the connection between truth and existence that the Epicureans also seem to recognise. I then examine a second Epicurean account of truth and falsehood and show how it is related to the first.

Epicurean epistemology is usually summarised in a controversial thesis according to which all perceptions are true. Although it seems very problematic and counterintuitive, careful investigation of the main sources shows us that Epicurus ’ claim for the truth of perceptions is not so hasty but is supported with some serious arguments. In the paper, I examine the thesis according to which “all perceptions are true”, but my main focus is to analyse the content of Epicurean perception through the following questions: (...) what kind of content do Epicurean perceptions have; what are the proper objects of perception; can we ascribe to such content truth and falsity? In the first part, I say something general about the thesis and point out some basic characteristics of perceptions due to which they serve as a criterion of truth. Next I try to show that the proper objects of perceptions are eidola and not external objects because only in that case can Epicurus maintain the truth of all perceptions, including illusions, hallucinations, dreams and other misperceptions. In the third part, I argue that such Epicurean perceptual content can be explained by the modern notion of non-conceptual content, which helps us to understand the special feature of Epicurean perceptions and also the important difference between perception and belief in Epicurean epistemology. In the final part, I discuss the notion of alethes which I suggest implies that perception is “factive”. (shrink)

Friendship and hedonism are both major components of Epicureanism. I attempt to relieve the tension that seems to follow from endorsing both of these. I argue that Epicurean friendships require valuing a friend’s well-being in the same way as one’s own and that embarking on such friendships is what David Schmidtz terms a maieutic end – one that is achieved by taking on a new set of ends. This conception fits with other-regarding concern that is espoused throughout the Epicurean texts (...) discussing friendship and, as I argue, remains consistent with other psychological and ethical commitments of Epicureanism.

The meaning of the term logagogy is elucidated, and logagogic practices are outlined in the history of medicine. It is shown how the traditional medicine of India, Ayurveda, shows signs of logagogic practices(sattvavajaya), and that not only Ayurveda but also the famous Greek physician Galenus emphasize a philosophical approach to medicine. As Galenus’s logagogic practices have their roots in the tradition of practical philosophy in Greek antiquity, the most important Greek schools of thought that are relevant to logagogic approaches are (...) sketched. It is shown that the Stoics created a rationalistic system emphasizing the importance of the logos for human beings, and that Epicurus made advances in psychoeducation and cognitive reframing that are important for logagogic practices. These logagogic approaches of antiquity have been taken up by modern counseling in philosophical practices. The article closes with an outline of a clinical logagogy. (shrink)
