A major new edition of the so-called Presocratics.The fragments and testimonia of the early Greek philosophers (often labeled the ‘Presocratics’) have always been not only a fundamental source for understanding archaic Greek culture and ancient philosophy but also a perennially fresh resource that has stimulated Western thought until the present day. This new systematic conception and presentation of the evidence differs in three ways from Hermann Diels’s groundbreaking work, as well as from later editions: it renders explicit the material’s thematic organization; it includes a selection from such related bodies of evidence as archaic poetry, classical drama, and the Hippocratic corpus; and it presents an overview of the reception of these thinkers until the end of antiquity.Volume I contains introductory and reference materials essential for using all other parts of the edition.Volume II presents preliminary chapters on ancient doxography, the cosmological and moral background, and includes the early Ionian thinkers Pherecydes, Thales, Anaximander, and Anaximenes.Volume III includes the early Ionian thinkers Xenophanes and Heraclitus.Volume IV presents Pythagoras and the Pythagorean School, including Hippasus, Philolaus, Eurytus, Archytas, Hicetas, and Ecphantus, along with chapters on doctrines not attributed by name and reception.Volume V includes the western Greek thinkers Parmenides, Zeno, Melissus, Empedocles, Alcmaeon, and Hippo.Volume Vi includes the later Ionian and Athenian thinkers Anaxagoras, Archelaus, and Diogenes of Apollonia, along with chapters on early Greek medicine and the Derveni Papyrus.Volume VII includes the atomists Leucippus and Democritus.Volume VIII includes the so-called sophists Protagoras, Gorgias, Prodicus, Thrasymachus, and Hippias, along with testimonia relating to the life, views, and argumentative style of Socrates.Volume IX includes the so-called sophists Antiphon, Lycophron, and Xeniades, along with the Anonymous of Iamblichus, the Dissoi Logoi, a chapter on characterizations of the ‘sophists’ as a group, and an appendix on philosophy and philosophers in Greek drama.

Nine leading scholars of ancient philosophy from Europe, the UK, and North America offer a systematic study of Book Beta of Aristotle''s Metaphysics. The work takes the form of a series of aporiai or ''difficulties'' which Aristotle presents as necessary points of engagement for those who wish to attain wisdom. The topics include causation, substance, constitution, properties, predicates, and generally the ontology of both the perishable and the imperishable world. Each contributor discusses one or two of these aporiai in sequence: the result is a discursive commentary on this seminal text of Western philosophy.

The Derveni papyrus is the oldest literary papyrus ever found, and one of the very few from Greece itself, which makes it one of the most interesting new texts from the ancient Greek world to have been discovered this century. The eschatological doctrines and an allegorical commentary on an Orphic theogony in terms of Presocratic physics which it contains make it a uniquely important document for the history of ancient Greek religion, philosophy, and literary criticism.This book is the first to have been published on the text. It includes a full and reliable translation of the Papyrus together with a range of articles by leading European and American classicists who are internationally recognised experts in Greek religion and philosophy. Professor K. Tsantsanoglou, who will publish the papyrus when work on it is complete, presents important new material and has checked all the articles against the Papyrus. Thus for the first time, material is provided which will authorize scholarship upon the Papyrus in a way hitherto impossible, will stimulate further work on it, and will make the book a standard reference work on the subject for years to come.

Hegel's often-echoed verdict on the apolitical character of philosophy in the Hellenistic age is challenged in this collection of essays, originally presented at the sixth meeting of the Symposium Hellenisticum. An international team of leading scholars reveals a vigorous intellectual scene of great diversity: analyses of political leadership and the Roman constitution in Aristotelian terms; Cynic repudiation of the polis - but accommodation with its rulers; Stoic and Epicurean theories of justice as the foundation of society; Cicero's moral critique of the traditional political pursuit of glory. The volume as a whole offers a comprehensive guide to the main currents of social and political philosophy in a period of increasing interest to classicists, philosophers and cultural and intellectual historians.

When we talk about Presocratic philosophy, we are speaking about the origins of Greek philosophy and Western rationality itself. But what exactly does it mean to talk about "Presocratic philosophy" in the first place? How did early Greek thinkers come to be considered collectively as Presocratic philosophers? In this brief book, Andre Laks provides a history of the influential idea of Presocratic philosophy, tracing its historical and philosophical significance and consequences, from its ancient antecedents to its full crystallization in the modern period and its continuing effects today. Laks examines ancient Greek and Roman views about the birth of philosophy before turning to the eighteenth-century emergence of the term "Presocratics" and the debates about it that spanned the nineteenth and twentieth centuries. He analyzes the intellectual circumstances that led to the idea of Presocratic philosophy--and what was and is at stake in the construction of the notion.The book closes by comparing two models of the history of philosophy--the phenomenological, represented by Hans-Georg Gadamer, and the rationalist, represented by Ernst Cassirer--and their implications for Presocratic philosophy, as well as other categories of philosophical history. Other figures discussed include Plato, Aristotle, Cicero, Diogenes Laertius, Schleiermacher, Hegel, Nietzsche, Max Weber, and J.-P. Vernant. Challenging standard histories of Presocratic philosophy, the book calls for a reconsideration of the conventional story of early Greek philosophy and Western rationality.

An argument for why Plato’s Laws can be considered his most important political dialogueIn Plato's Second Republic, André Laks argues that the Laws, Plato’s last and longest dialogue, is also his most important political work, surpassing the Republic in historical relevance. Laks offers a thorough reappraisal of this less renowned text, and examines how it provides a critical foundation for the principles of lawmaking. In doing so, he makes clear the tremendous impact the Laws had not only on political philosophy, but also on modern political history.Laks shows how the four central ideas in the Laws—the corruptibility of unchecked power, the rule of law, a “middle” constitution, and the political necessity of legislative preambles—are articulated within an intricate and masterful literary architecture. He reveals how the work develops a theological conception of law anchored in political ideas about a god, divine reason, that is the measure of political order. Laks’s reading opens a complex analysis of the relationships between rulers and citizens; their roles in a political system; the power of reason and persuasion, as opposed to force, in commanding obedience; and the place of freedom.Plato's Second Republic presents a sophisticated reevaluation of a philosophical work that has exerted an enormous if often hidden influence even into the present day.
