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.

This paper is a commentary on Epicurus’ Kuria Doxa 33, according to which “justice is not anything in itself [τι καθ᾽ ἑαυτό].” It explores what it means for something to exist ‘in itself’ in Hellenistic philosophy, speculating on the sources of Epicurean technical vocabulary and suggesting an ontological reading of KD 33.

This paper analyzes the ontology and epistemology of time in Lucretius’ De rerum natura. It uses the physiology of perception as well as epistemology to shed new light on the metaphysics. It presents an exegesis-based interpretation of the nature of time and of its perception, both arguing for and refining this interpretation by showing its explanatory power. The paper shows that Lucretius represents the perception of time or sensus temporis as a distinct sensory faculty, reconstructs how it emerges and operates, (...) and relates it to his account of perception more generally. The sense of time in turn is seen to explain aspects of related faculties, including thought and sight, and cases of apparent simultaneity. The paper thus contributes to, among other things, our understanding of the speed of perception and Lucretius’ account of the nature of time itself — arguing that Lucretius represents time as both continuous (not atomic) and real, as well as something perceived.
