The two studies, "Indivisible Magnitudes," and “Aristotle and Epicurus on Voluntary Action,” explain two doctrines in the philosophy of Epicurus, first by a detailed examination of the ancient Greek and Latin texts which describe them, and second by showing how earlier Greek philosophy gave rise to the problems Epicurus tackled.

A new presentation of the evidence for the thought of Leucippus and Democritus, based on the original sources. Includes the Greek text of the fragments with facing English translation, notes, commentary, and complete indexes and concordances.

The earliest phase of philosophy in Europe saw the beginnings of cosmology and rational theology, metaphysics, epistemology, and ethical and political theory. It saw the development of a wide range of radical and challenging ideas: from Thales' claim that magnets have souls and Parmenides' account that there is only one unchanging existent to the development of an atomist theory of the physical world. This general account of the Presocratics introduces the major Greek philosophical thinkers from the sixth to the middle of the fifth century BC. It explores how we might go about reconstructing their views and understanding the motivation and context for their work as well as highlighting the ongoing philosophical interest of their often surprising claims. Separate chapters are devoted to each of the major Presocratic thinkers, including Xenophanes, Heraclitus, Parmenides, Anaxagoras, Empedocles, Leucippus and Democritus, and an introductory chapter sets the scene by describing their intellectual world and the tradition through which their philosophy has been transmitted and interpreted. With a useful chronology and guide to further reading, the book is an ideal introduction for the student and general reader.

Scholars have long recognized Lucretius's De Rerum Natura as an important allusive source for the Aeneid, but significant disagreement persists regarding the scope and purpose of Virgil's engagement with Epicurean philosophy. In Atomism in the Aeneid, Matthew M. Gorey investigates that engagement and argues that atomic imagery functions as a metaphor for cosmic and political disorder in Virgil's epic, associating the enemies of Aeneas and of Rome's imperial destiny with the haphazard, purposeless chaos of Epicurean atoms in the void. While nearly all of Virgil's allusions to atomism are constructed from Lucretian intertextual material, Gorey shows how the poet's negative reception of atomism draws upon a long and popular tradition of anti-atomist discourse in Greek philosophy that metaphorically likened the non-teleological cosmology of atomism to civic disorder and mob rule. By situating Virgil's atomic allusions within the tradition of philosophical opposition to Epicurean physics, Atomism in the Aeneid illustrates the deeply ideological nature of his engagement with Lucretius.

The legacy of ancient Greece and Rome has been imitated, resisted, misunderstood, and reworked by every culture that followed. In this volume, some five hundred articles by a wide range of scholars investigate the afterlife of this rich heritage in the fields of literature, philosophy, art, architecture, history, politics, religion, and science.

This collection introduces readers to some of the most respected Pre-Socratic scholarship of the twentieth century. It includes translations of important works from European scholars that were previously unavailable in English and incorporates the major topics and approaches of contemporary scholarship. Here is an essential book for students and scholars alike. "Students of the Pre-Socratics must be grateful to Mourelatos and his publishers for making these essays available to a wider public."--T. H. Irwin, American Journal of Philology "Mourelatos is a superb editor, and teaching Pre-Socratics in the future with this collection on the reading list will not only be easier but also better."--Jorgen Mejer, The Classical World "The editor has done his work judiciously. It would be difficult to devise a better balance between different parts of the subject."--Edward Hussey, Archives internationales d'histoire des sciences "[This book] will undoubtedly become an indispensable aid for beginning and advanced students of the Pre-Socratics."--David E. Hahm, Isis Originally published in 1994.

These first philosophers paved the way for the work of Plato and Aristotle - and hence for the whole of Western thought. This is a unique and invaluable collection of the works of the Presocratics and the Sophists. Waterfield brings together the works of these early thinkers with brilliant new translation and exceptional commentary. This is the ideal anthology for the student of this increasingly appreciated field of classical philosophy.

In Knowledge and Cosmos: Development and Decline of the Medieval Perspective, 2nd Edition, Robert K. DeKosky focuses on issues in astronomy, cosmology, physics, matter theory, philosophy, and theology vital to the “Copernican Revolution.” This book describes efforts among individuals advocating different world views to fit new ideas compatibly into broad perspectives reflecting four traditional patterns of interpretation: teleological, mechanical, occultist, and mathematico-descriptive. These four modes had guided medieval accounts of heavenly phenomena, material process, and motion. The teleological explanation, prevalent in Aristotle’s natural philosophy, posited “final causes” (ends or goals toward which objects strove or attempted to become). Ancient classical atomists had emphasized strictly mechanical explanations, invoking direct material contact and collision of moving matter as agents of physical change. Traditions of astrology, magic, and alchemy embraced an occultist pattern of interpretation—citing hidden forces opaque to both sensual detection and rational understanding as explanations of various phenomena. Finally, the mathematico-descriptive approach interpreted natural phenomena according to geometric or arithmetic relationships; unlike the other three, this did not involve causal explanation of a process. Part I discusses development of the four patterns in the ancient period and their uneasy medieval relationships with each other and with basic Judaeo-Muslim-Christian exigencies of faith. Theory of the heavens follows, including the mathematico-descriptive approach of Ptolemaic astronomy, the teleological and mechanical cosmology of Aristotle, and occultist interpretations of astrologers and magicians. Part I then turns to matter and materiality, discussing differences among the mechanical philosophy of classical atomism, teleological emphases in Aristotle’s material theory, and occultist assumptions of some alchemists. Finally, Part I analyzes conceptions of motion, focusing on Aristotelian interpretations and critical commentaries thereon during the Middle Ages. Part II relates struggles of leading early-modern figures to adapt new concepts (e.g., Copernicus’ heliocentric astronomy/cosmology, Galileo’s inertial theories of motion, and Kepler’s elliptical planetary orbit) to an allegiance to two or more of the four patterns of interpretation. By this approach, it identifies decreasing dependence on teleological explanation of physical phenomena as crucial to decline of medieval interpretations of those phenomena, followed by rejection of teleology in the natural philosophy of Descartes, and subsequent fruitful confluence of the mechanical, mathematico-descriptive, and occultist patterns in the physics and cosmology of Isaac Newton.

This book presents two new interpretations of the evidence regarding the metaphysical ideas of two important figures in Plato's Academy, Eudoxus and Speusippus, and of Aristotle's reaction to those ideas. The central question has to do with Plato's "Theory of Forms." The first interpretation portrays Eudoxus reviving a view of Anaxagoras' and advocating that the Forms are physical ingredients in things. This has affinities with Aristotle's own view, so it is interesting that Aristotle argues for its rejection. The essay extracts Aristotle's arguments from material in late sources and examines them in depth. The second interpretation discusses Speusippus' replacement of the Theory of Forms with a theory that derives all that there is from the One, which does not itself exist. His argument for this strange position is reconstructed, and the relations between the theory of causality, to which it is opposed, are laid out. The Academy was not a source of dogma, but of discussion. In reconstructing central aspects of that discussion, these interpretations seek to get behind mere reportage of what little is known to the actual arguments current in the halls of the Academy.

The translation is based on the most authoritative edition of the Greek text. 'Lives of the Eminent Philosophers' is a crucial source for much of what we know about the origins of philosophy in ancient Greece. Accompanied by dozens of artworks and newly commissioned essays that shed light on Diogenes' context and influence, this new, complete translation provides a revealing glimpse into the philosophers of Plato's Academy, Aristotle's Lyceum, and Epicurus' Garden.
