B 115 is generally regarded as the reference fragment of Empedocles’ doctrine of rebirth, being the place where he presents himself as a god banished from the divine community as a result of certain crimes, sent into exile on our earth and here condemned to be reborn as all kinds of mortal beings. In Chapter 1 I argue that, contrary to the vast majority of editions of Empedocles’ fragments, B 115 belongs to the incipit of his physical poem. The chapter mostly focuses on the Strasbourg papyrus and the evidence it uncovered that is relevant to the question of the character and content of the physical poem. After questioning the basis on which scholars have placed B 115 within the Purifications, I will show that the Strasbourg papyrus provides strong proof for its allocation within On Nature. The relocation of this central fragment thus sets the stage for a re-evaluation of Empedocles’ physical system in its entirety, by indicating that it consists of mythical and religious themes in synergy with more strictly physical principles.

By first providing a summary of the main arguments in each chapter and then highlighting the ways, elaborated in this study, in which Empedocles’ physics is consistent with his religious interests in rebirth and purification, Chapter 8 sets out the main conclusion of this book, namely that rebirth and purification are an integral part of Empedocles’ physical system; indeed, that rebirth seems to be a premise of some of his physical principles and theories. In doing so, in addition to a new textual reconstruction of the proem of the physical poem, this book offers new insights into pivotal concepts and much debated issues of Empedocles’ thought, such as the conceptualization of rebirth and the notions of daimon, soul and personal survival, the purpose and role of physical doctrine for release from rebirth, the reconstruction of the cosmic cycle and the analysis of its moral significance. Finally, it is emphasized that this novel reconstruction of Empedocles’ thought, together with the book’s methodological standard, can provide a key to approaching and re-evaluating the character and aims of the thought of other early thinkers and of fifth-century natural philosophy in general.

Aiming at reconstructing the prologue to On Nature, the first part of this chapter focuses on the collocation of the demonological fragments which, by expanding on Empedocles’ exile introduced in B 115, depict his katabasis into the realm of the dead. The narrative of this extraordinary journey serves Empedocles as authorial legitimation on matters beyond ordinary human knowledge. The second part of Chapter 2 reconstructs the rest of the proem by interweaving traditionally introductory themes, such as the dedication to Pausanias and the invocation to the Muse, with novel topics concerning the rejection of ritual sacrifice based on Empedocles’ concept of rebirth. The proem thus reconstructed presents a coherent programmatic structure and makes sense of several Empedoclean fragments that are essential for a comprehensive and impartial understanding of his thought. Moreover, by showing that religious concerns inform the entire introductory section, the new proem indicates that the concept of rebirth is central to Empedocles’ physical system and thus offers a new basis to rethink the interplay of myth, religion, and physics in his natural philosophy.

In the Introduction I set out the main argument of the book, namely the demonstration that Empedocles’ doctrine of rebirth is not only a positive doctrine within On Nature, but is central to his physical system. Then, after briefly tracing the history of the reception of Empedocles’ thought up to the modern era and showing thereby the importance of this thinker in the history of ancient philosophy, I discuss the state of the art related to the book’s main argument. Building on Kahn’s fundamental reappraisal of Empedocles’ doctrinal unity, my book considers the Strasbourg papyrus as evidence for a new reconstruction of Empedocles’ physical poem and thus for a rethinking of his philosophy in terms of a unified system of thought. Therefore, by aiming to demonstrate the ways in which Empedocles’ physics integrates, on a textual and contextual basis, the details of his doctrine of rebirth, sometimes even giving the impression of being premised on it, it is argued that this study is also relevant to a reassessment of the nature and intent of ancient Greek philosophy in general.
