In _Metaphysics_ A.4, Aristotle provides crucial information about fundamental aspects of the chemistry and microphysics of the atomic theory of Leucippus and Democritus of Abdera. Besides the plenum and the void, which he identifies as the elements of the atomic theory, he presents what he himself names as _differences_. These fundamental differences are named so because they ought to be responsible for the emergence of all other differences in the physical world, and especially the ones that hit our senses. Aristotle (...) provides a list of three differences both in what is recognized as autochthonous terminology from Leucippus and Democritus, and in a translation to terms apparently more intelligible to Aristotelian listeners. Among those differences there is one in particular that is harder to comprehend than the other ones: _rhysmos_. Aristotle’s translation of _rhysmos_ into _sch__ēma_ has led most interpreters to acknowledge that it referred solely to atoms individually, while the other two differences would refer to relations between atoms. In this paper, I want to propose an interpretation in which _rhysmos_ actually refers to several aspects of the chemistry and microphysics of the atomic theory. (shrink)

Okeanos is at once a mythological figure and a philosophical concept appearing in many ancient accounts of the world. A frequent object of allegoresis, his cosmological role and his name posed an enigma to Homer’s readers, especially those with a rationalizing bent. This paper proposes that the paradoxical representation of Okeanos as a primordial generative power and a geographical limit may be explained by the influence of etymological speculation, which was a popular heuristic method used by Greek intellectuals from the (...) archaic period throughout antiquity.

With respect to Parmenides’ thought Melissus was regarded as a dissident thinker already in antiquity. His polemical introduction of the concept of void and the relative idea of infinite Being seemed particularly controversial. The aim of the present paper is to examine the origins of the Melissian understanding of void in order to trace its philosophical genesis to the criticism of the Atomist Leucippus. According to the philosopher from Abdera, the Eleatic fundamental principles had to conform to the obviousness of (...) bodies’ motion, which is why the Eleatic not-Being had to be understood as void. Melissus took issue with this view and criticized the idea of the void’s reality by means of a methodical argument. In the course of doing so, the philosopher from Samos distorted the original Parmenidean ontology, which is why his theories were often criticized severely as theoretically weak. (shrink)

The inclusion of De astrologia in the Lucianic corpus has been disputed for centuries since it appears to defend astrological practices that Lucian elsewhere undercuts. This paper argues for Lucian’s authorship by illustrating its masterful subversion of a captatio benevolentiae and subtle rejection of Stoic astrological practices. The narrator begins the text by blaming phony astrologers and their erroneous predictions for inciting others to “denounce the stars and hate astrology” (ἄστρων τε κατηγοροῦσιν καὶ αὐτὴν ἀστρολογίην μισέουσιν, 2). The narrator assures (...) readers that he, the knowledgeable astrologer, will correct for the “stupidity and laziness” (ἀμαθίῃ καὶ ῥαθυμίῃ, ibid.) that bring about false predictions. The narrator’s credibility quickly decays when he attempts to recast Orpheus, Bellerophon, Icarus, Daedalus, and a host of other mythological figures as Greek astrologers. Lucian’s audience would expect such far-fetched interpretations of myth from the stereotypical Stoic philosopher, a character lampooned elsewhere in the Lucianic corpus. (shrink)

The label idios apodeixis/logos «particular demonstration or argument» of Gorgias is known to us only from the third section of the little work attributed to Aristotle under the title De Melisso, Xenophane, Gorgia. Its authenticity seems to be unjustly questioned. We try to show that from the Aristotelian perspective we can properly understand the context of Gorgias’ own argument from his lost treatise On Not-Being or On Nature. Parmenides – using implicitly the polysemy of the verb ἔστιν/εἶναι – presented a (...) certain ontological argument «being is, because being is being». Gorgias, however, makes a parody of this by offering a meontological argument: «not-being is because not-being is not-being». Consequently Gorgias then attempts to demonstrate, by means of refutation, that «it is not either to be or not be», i.e. «nothing is». We propose, thus, a reconstruction of Gorgias’ account of meonological and nihilistic argumentation. In this context we find in Plato’s Sophist and in Aristotle’s writings certain allusions to Gorgias’ idios apodeixis, which have not been sufficiently recognized and properly interpreted. (shrink)
