In contemporary metaphysics, the Eleatic Principle (EP) is a causal criterion for reality. Articulating the EP with precision is notoriously difficult. The criterion purportedly originates in Plato’s Sophist, when the Eleatic Visitor articulates the EP at 247d-e in the famous Battle of the Gods and the Giants. There, the Visitor proposes modifying the ontologies of both the Giants (who are materialists) and the Gods (who are friends of the many forms), using a version of the EP according to which only (...) items which have the capacity to affect or to be affected are real. Recently, it has been argued that while there are some genetic connections between the EP and the views of some of the historical Eleatics (Parmenides and Zeno), the views of Melissus are generally incompatible with the EP. This raises the following question: What, exactly, is Eleatic about the Eleatic Principle? In this paper, I look to the dialectical context in which the Visitor’s appeal to the EP appears, and I propose that there are at once three relevant senses of affecting and being affected in the text: (1) tangible contact (as in the interactions between the bodies of the materialists), (2) Cambridge change (as in the form's being affected by a soul via the act of coming to know), and (3) the notion of a cause that does not itself change (as in a form’s affecting another form, a soul, or any sensible item). I argue that these have clear parallels to the metaphysics of all three main Eleatic philosophers, and that the views of Parmenides, Zeno, and Melissus are therefore compatible with the EP. This has interesting consequences for narratives about the reception of the Eleatics in Plato, the inclusion of an Eleatic Visitor as an interlocutor in the Sophist, and for the metaphysics of subsequent schools (such as the Stoics) who are widely thought to have been influenced by the EP.

Giovanni Pico della Mirandola (1463-1494) decided to study all the ancient and medieval schools of philosophy, including the Pre-Socratics, in order to broaden his scope. Pico showed interest in ancient monists. He commented that only Xenophanes’ One is the One simply, while Parmenides’ One is not the absolute One, but the oneness of Being. Melissus’ One is in extreme correspondence to that of Xenophanes. As for Xenophanes, Pico seems to have fallen victim of ancient sources, who referred to Xenophanes (...) and Parmenides as members of the Eleatic “tribe”. In the case of Parmenides Pico draws mainly on the Platonic dialogues Parmenides and Sophist and not on intermediaries such as the Neoplatonists and other commentators. Despite of Pico’s knowledge of Empedocles’ philosophy, it is worth noticing that Pico was also strongly influenced by the medieval kabbalistic literature and the pseudo Empedocles. While Neoplatonists, such as Proclus, commented Empedocles and interpreted him according to the Neoplatonic spectrum, Pico’s appreciation of the philosophy of Empedocles was mediated through Arab and Jewish mysticism. Pico counted among his sources the Pre-Socratics, but the way he read them was not always direct and consistent. He intentionally chose to interpret them through the spectrum of intermediaries such as the ancient Commentators, the Neoplatonists, the Arabs and Jews mystics. (shrink)
