Lucretius devotes some sections of his De rerum natura to the treatment of dreams. He is particularly interested in the phenomenon of dream deception, namely the belief that the dreamt object is the object itself. This psychological phenomenon has some both unwanted and philosophically interesting implications. Firstly, from an ethical point of view, it can stimulate uncontrolled worries and feelings in the dreamer that undermine his/her mental tranquility and health. Secondly, from a physiological perspective, it seems to reveal a failure (...) in the mechanism undergoing the formation of mental representation. Thirdly, from the epistemological point of view, it seems to compromise the veracity of mental representations. This paper aims to explain how Lucretius dealt with this phenomenon. In particular, it will show how he succeeded, on the one hand, to explain the nature and the origin of dream deception and of its emotional aspect, and, on the other hand, to preserve the informative contents of dreams and their correspondence to reality. For this purpose the present essay will address the following issues: which is the condition of the soul and of the mind while sleeping; what kind of mental activity is dreaming; which is the nature and the origin of the simulacra responsible for dreams; which is the contents of dreams and how dream deception comes about; and finally why and how dream deception emotionally effects the dreamer.

En plus de concevoir la vue et la pensée comme des processus empiriques capables de reproduire les caractéristiques des corps, Épicure reconnaît un processus psychophysique intermédiaire par le biais duquel les phantasiai ou représentations sont produites dans l’esprit et synthétisent les caractéristiques des objets sensibles. L’objectif de cet article est de monter qu’Épicure a retravaillé la doctrine de Démocrite dans cette direction, à la lumière de la critique aristotélicienne de certaines théories de la perception et de sa réflexion sur la (...) formation du phantasma. Nous étudions le processus physiologique à l’origine de la phantasia chez Épicure, et nous montrons son lien avec le processus psychophysique adopté par Aristote pour expliquer la représentation.

Aristote estime qu’une vie consacrée à gagner de l’argent ne mérite pas d’être vécue, dans la mesure où elle est sujette à des contraintes et fondée sur une conception pervertie de la richesse. Cependant, il assigne à l’argent une valeur instrumentale en tant qu’il est indispensable au bonheur, et il reconnaît qu’il y a des tendances naturelles à la richesse en tout agent. Cet article se propose de clarifier les thèses d’Aristote concernant la fonction de la richesse dans son rapport (...) à une vie bonne, concernant ce qui garantit l’usage correct des biens et comment il est possible de promouvoir la pratique de la chrématistique naturelle face à l’extension des formes perverties de recherche du profit. L’article entend ensuite montrer quelles vertus sont liées à la richesse – générosité, magnificence et justice ou équité – et comment elles se rattachent aux vices opposés – c’est-à-dire : prodigalité et avarice, tendance dépensière et pingrerie, et injustice ou inéquité. L’intention de cette étude est d’expliquer pourquoi l’enquête aristotélicienne sur les bonnes et mauvaises habitudes liées à l’usage de la richesse est complémentaire de l’enquête sur la genèse des phénomènes économiques, et pourquoi elle vise à garantir dans la pratique une chrématistique parfaitement intégrée à l’éthique et à la politique.

Epicureanism is not only a defence of pleasure: it is also a philosophy of science and knowledge. This edited collection explores new pathways for the study of Epicurean scientific thought, a hitherto still understudied domain, and engages systematically and critically with existing theories. It shows that the philosophy of Epicurus and his heirs, from antiquity to the classical age, founded a rigorous and coherent conception of knowledge. This first part of a two-volume set examines more specifically the contribution of Epicureanism (...) in the fields of language, medicine, and meteorology (i.e., celestial, geological and atmospheric phenomena). Offering a renewed image of Epicureanism, [volume 1] includes studies on the nature of human language and on the linguistic aspects of scientific discourse; on the relationship between Epicureanism and ancient medicine, from Hippocrates to Galen; on meteorological phenomena and the method of explaining them; and on the reception of Epicurus's legacy in Gassendi.

In this paper I will examine a difficulty (aporia), which Aristotle raises in Physics B 5.197a20-25: whether fortuitous things can be held as causes of luck. I will show the meaning of the passage and its relevance within the context of Aristotelian extended analysis of the notions of ``luck'' and ``chance''. I will claim that, in facing the problem, Aristotle has a twofold aim. Firstly, he wants to explain why luck is, after having enquired whether it exists and what it (...) is. Secondly, he wants to prevent his pupils, among others, from denying causal efficacy to luck, by reducing fortuitous events, that are the result of accidental causes, to the action of per se causes, such as nature and human deliberation.
