Epicurus emphatically asserts the veracity of perception, including visual perception, yet most of the literature on Epicurus’ atomistic theory of vision pays scant attention to what Epicurus believed transpires outside the body that leads to it. The treatments by DeWitt, Everson, Hicks, and Rist are all very brief; Glidden focuses primarily on the processes occurring inside the perceiver; and while the discussions by Asmis and Bailey are more detailed, they hardly more than note in passing that the process is problematic.1 (...) In this paper I will critically examine Epicurus’ theory of vision, in particular his theory of the events occurring between perceived objects and the eye. I will argue that while certain common objections to Epicurus’ theory may be answerable, it nevertheless suffers from serious problems. These problems, in turn, occur on two levels. On the mechanical level, it demands that dissimilar atomic complexes behave in strikingly similar ways. And on the theoretical level, there is tension created by the need for the intermediary between objects and the observer to be both like objects and unlike them. (shrink)

Epicurus is one of the first social contract theorists, holding that justice is an agreement neither to harm nor be harmed. He also says that living justly is necessary and sufficient for living pleasantly, which is the Epicurean goal. Some say that there are two accounts of justice in Epicurus -- one as a personal virtue, the other as a virtue of institutions. I argue that the personal virtue derives from compliance with just social institutions, and so we need to (...) attribute only one account of justice to Epicurus. I show how this interpretation makes sense of claims about justice by Epicurus and his followers, including Hermarchus, Lucretius, and Diogenes of Oinoanda. (shrink)

O'Keefe's contention that Epicurus devised the atomic swerve to counter a threat to the efficacy of reason posed by the thesis that the future is fixed regardless of what we do, is not supported by the evidence he adduces. Epicurus' own words in On nature XXV, and testimony from Lucretius and Cicero, tell far more strongly in favour of the traditional view, that Epicurus' concerns were causal determinism and its threat to moral responsiblity for our actions and characters.

For the purpose of this paper, I assume that if a person is morally responsible for an action, this is a necessary and sufhcient condition for moral appraisal of that person for that action. For instance, if the action is morally wrong, moral blame is in order. Other morally relevant responses that are sometimes connected with moral responsibility are praise, pardon, shame, pride, reward, punishment, remorse. I now introduce two quite different concepts of moral responsibility: one grounded on the causal (...) responsibility ofthe agent for an action, the other on the ability of the agent to do otherwise. The one based on the agent’s causal responsibility considers it a necessary condition for praising or blaming an agent for an action, that it was the agent and not something else that brought about the action. The question of moral responsibility becomes one of whether the agent was the or a cause of the action, or whether the agent was forced to act by something else. On this view, actions or choices can be attributed to agents because it is in their actions and choices that the agents, quo moral beings, manifest themselves. The second idea of moral responsibility considers it a prerequisite for blaming or praising an agent for an action that the agent could have done otherwise. This idea is often connected with the agents, sentiments or beliefs that they could have done otherwise, as well as the agents’ feelings of guilt or regret, or pride, for what they have done. Some philosophers consider the causal indeterminedness of the agent’s decision to act as necessary to warrant that the agent could have done otherwise. (shrink)

: In Contra Academicos 3.11.24, Augustine responds to skepticism about the existence of the external world by arguing that what appears to be the world — as he terms things, the "quasi-earth" and "quasi-sky" — cannot be doubted. While some (e.g., M. Burnyeat and G. Matthews) interpret this passage as a subjectivist response to global skepticism, it is here argued that Augustine's debt to Epicurean epistemology and theology, especially as presented in Cicero's De Natura Deorum 1.25.69 - 1.26.74, provides the (...) basis for a much more plausible, realist interpretation of Augustine's argument.

The paper deals with the question of the attribution to Epicurus of the classification of pleasures into 'kinetic' and 'static'. This classification, usually regarded as authentic, confronts us with a number of problems and contradictions. Besides, it is only mentioned in a few sources that are not the most reliable. Following Gosling and Taylor, I believe that the authenticity of the classification may be called in question. The analysis of the ancient evidence concerning Epicurus' concept of pleasure is made according (...) to the following principle: first, I consider the sources that do not mention the distinction between 'kinetic' and 'static' pleasures, and only then do I compare them with the other group of texts which comprises reports by Cicero, Diogenes Laertius and Athenaeus. From the former group of texts there emerges a concept of pleasure as a single and not twofold notion, while such terms as 'motion' and 'state' describe not two different phenomena but only two characteristics of the same phenomenon. On the other hand, the reports comprising the latter group appear to derive from one and the same doxographical tradition, and to be connected with the classification of ethical docrines put forward by the Middle Academy and known as the divisio Carneadea. In conclusion, I argue that the idea of Epicurus' classification of pleasures is based on a misinterpretation of Epicurus' concept in Academic doxography, which tended to contrapose it to doctrines of other schools, above all to the Cyrenaics' views.

Epicurus seems to have thought that death is not bad for the one who dies, since its badness cannot be located in time. I show that Epicurus’ argument presupposes Presentism, and I argue that death is bad for its victim at all and only those times when the person would have been living a life worth living had she not died when she did. I argue that my account is superior to competing accounts given by Thomas Nagel, Fred Feldman and (...) Neil Feit. (shrink)

I reject the traditional picture of philosophical withdrawal in the Hellenistic Age by showing how both Epicureans and Stoics oppose, in different ways, the Platonic and Aristotelian assumption that contemplative activity is the greatest good for a human being. Chrysippus the Stoic agrees with Plato and Aristotle that the greatest good for a human being is virtuous activity, but he denies that contemplation exercises virtue. Epicurus more thoroughly rejects the assumption that the greatest good for a human being is virtuous (...) activity. He maintains that the greatest good for a human being is the tranquility that virtuous activity always and contemplative activity sometimes brings about. (shrink)

This article questions the assumption, held by several philosophers, that the Epicurean argument for death's being “nothing to us” must be fallacious since its acceptance would undermine the principle that killing is (in general) wrong. Two possible strategies are considered, which the Epicurean-sympathizer might deploy in order to show that the non-badness of death (for the person who dies) is compatible with killing's being wrong. One of these is unsuccessful; the other is more promising. It involves arguing that the wrongness (...) of killing is a “basic moral certainty” and hence requires no underpinning by the judgement that death is bad. Problems for this proposal, and possible responses to those problems, are considered. Though the strategy is not decisive, it is deemed to be one that the Epicurean could plausibly adopt. (shrink)

In his article 'The Evil of Death' (henceforth: ED) Harry Silverstein argues that a proper refutation of the Epicurean view that death is not an evil requires the adoption of a particular revisionary ontology, which Silverstein, following Quine, calls 'four-dimensionalism'.1 In 'The Evil of Death Revisited' (henceforth: EDR) Silverstein reaffirms his earlier position and responds to several criticisms, including some targeted at his ontology. There remain, however, serious problems with Silverstein's argument, and I shall highlight five major ones below. I (...) conclude that Silverstein has not shown that an appeal to four-dimensionalism facilitates a refutation of Epicurus, although a consideration of some of Silverstein's points helps to indicate the limited scope of the Epicurean thesis.

According to Epicureans, anticipating one's own annihilation ought not to be a frightening experience. Non-existence precludes the possibility of sensation, and hence annihilation can be neither pleasant nor unpleasant. And that which cannot be felt is unworthy of fear. Certain objectors to this claim have asserted that one's own annihilation really is a terrifying prospect. Against this assertion, I argue that those who make it are guilty of precisely the kind of confusion that Epicurus and his disciples alert us to, (...) namely that of projecting ourselves into the thought of our own non-existence. A further objection to Epicureanism involves the claim that, since the fear of death is merely the converse of the love of life, the one cannot be extinguished without inevitably extinguishing the other (to inevitably disastrous effect). I argue that this objection relies upon an exaggeration of thanatological fear's power and an unduly pessimistic assessment of human reason's capacity to positively modify emotional states and dispositions. I conclude that neither of the objections considered here has vindicated the fear and anxiety commonly associated with anticipating one's annihilation, and that the Epicurean attempt to deflate these debilitating emotions remains valid.

Lucretius' account of the origin of life, the origin of species, and human prehistory (first century BC) is the longest and most detailed account extant from the ancient world. It is a mechanistic theory that does away with the need for any divine design, and has been seen as a forerunner of Darwin's theory of evolution. This commentary seeks to locate Lucretius in both the ancient and modern contexts. The recent revival of creationism makes this study particularly relevant to contemporary (...) debate, and indeed, many of the central questions posed by creationists are those Lucretius attempts to answer.
