This paper aims to investigate the equivalent of Epicurus’ πρόληψις, the second criterion of the Epicurean Canonic (DL X 31 = fr. 35 Usener), in Lucretius’ De rerum natura (DRN). Taking stock of the several occurrences of the Latin terms notitia and notities in the six books of the poem, I show that Lucretius’ view about preconception remains faithful to Epicurus’ πρόληψις, and that the poet does not endorse a less empiricist position than his Master because of some influence of (...) the Stoic ἔννοια. To this end, I will also briefly address an important case in which πρόληψις, albeit not clearly mentioned, plays an essential role, namely the prolepsis of the deity (DRN V 1169–1182). Finally, I explain how Lucretius can be of some help in grasping the controversial relationship between the criterion of πρόληψις and that of ἐπιβολὴ τῆς διανοίας (animi inectus/iactus), showing in which way the poet seems to consider the latter as a criterion of truth in its own right.

The surviving writings of Epicurus and his followers contain several references to epibolê – a puzzling notion that does not receive discussion in the extant Epicurean texts. There is no consensus about what epibolê is, what it is of, and what it operates on and, moreover, its epistemological status is controversial. This article aims to address these issues in both Epicurus and later Epicurean authors. Part One focuses mainly on Epicurus’ Letter to Herodotus, highlights a crucial distinction hitherto unnoticed in (...) the literature between two different types of epibolê, and brings out he necessary connection between epibolê and the application of the criteria of truth. Part Two considers the philosophical merits of the traditional interpretation of epibolê as projection and/or attention. Part Three examines the two aforementioned types of epibolê in Lucretius and Philodemus and shows that these authors accord epibolê paramount epistemological and ethical importance. (shrink)

This paper discusses ἐπιβολαὶ τῆς διανοίας, which later Epicureans are supposed to have elevated to a fourth criterion of truth to complement perceptions, preconceptions and feelings. By examining Epicurus’ extant writings, the paper distinguishes three different senses of the term: ‘thought in general’, ‘act of attention’ and ‘mental perception’. It is argued that only the sense ‘mental perception’ yields a plausible reading of ἐπιβολαί as a criterion of truth. The paper then turns to the textual evidence on ἐπιβολαί in later (...) authors. While the term ἐπιβολή is not used by Cicero, Lucretius and Philodemus in the sense of mental perception, it is argued that this still is the most plausible way of understanding ἐπιβολή as a criterion of truth.

There is no single ancient Greek word in the surviving fragments and testimonies of Hellenistic philosophy that is directly translatable by the term ‘intuition’. But if we are in search of intuitions in the context of Hellenistic epistemology, it could be said that both the Stoics and the sceptics made use of them in their philosophical debates; for intuitions seem to be closely connected with the formation of conceptions, which were abundantly used by all Hellenistic philosophers. It is important to (...) understand, though, that the Stoics’ and the sceptics’ attitude towards the epistemic status of intuitions would greatly differ: The Stoics would explain intuitions by invoking a rational capacity of human beings, which based on experience would put them in touch with the reality of things, so that their intuitions could be thought of as somehow rationally admissible. The sceptics, on the other hand, would suggest that intuitions guide our everyday life merely on the basis of our previous experiences, and thus their intuitions could be regarded as empirically justified, although they would not guarantee any access to how things actually are.

Este artículo examina la preconcepción epicúrea y diversos problemas relacionados con su adquisición y función, tanto en el ámbito teórico como en el práctico. Los autores ponen de relieve que en el modelo contractual epicúreo la justicia constituye una modalidad de lo útil y la preconcepción de lo justo opera como un canon para validar las leyes en las comunidades políticas. Examinan asimismo el vínculo entre el lenguaje y la justicia en el epicureísmo, centrándose primero en el papel del lenguaje (...) en la genealogía epicúrea de la justicia y, luego, en las conexiones entre el aprendizaje del lenguaje y la prolepsis de lo justo en las comunidades políticas constituidas. Subrayan, para concluir, que el aprendizaje del lenguaje es un ingrediente relevante de la experiencia para comprender la génesis empírica de la preconcepción epicúrea. (shrink)

À partir de l’analyse d’un passage du Contre les géomètres de Sextus Empiricus, cet article tente d’évaluer la signification réelle ainsi que les con­séquences épistémiques de la destruction épicurienne des objets de la géométrie. L’existence du clinamen ainsi que le schème explicatif des explications multiples sont interprétés comme des résultats positifs du refus par Épicure de toute géo­métrisation de la nature.
