Plato famously promised to complement the Sophist and the Statesman with another work on a third sort of expert, the philosopher-but we do not have this final dialogue. Mary Louise Gill argues that Plato promised the Philosopher, but did not write it, in order to stimulate his audience and encourage his readers to work out, for themselves, the portrait it would have contained. The Sophist and Statesman are themselves members of a larger series starting with the Theaetetus, Plato's investigation of knowledge, and the whole series relies on the Parmenides, the second part of which presents a philosophical exercise, introduced as the first step in a larger philosophical program. Gill contends that the dialogues leading up to the missing Philosopher, though they reach some substantive conclusions, are philosophical exercises of various sorts designed to train students in dialectic, the philosopher's method; and that a second version of the Parmenides exercise, closely patterned on it, spans parts of the Theaetetus and Sophist and brings the philosopher into view. This is the exercise about being, the subject-matter studied by Plato's philosopher. Plato hides the pieces of the puzzle and its solution in plain sight, forcing his students (and modern readers) to dig out the pieces and reconstruct the project. Gill reveals how, in finding the philosopher through the exercise, the student becomes a philosopher by mastering his methods. She shows that the target of Plato's exercise is internally related to its pedagogical purpose.

The Parmenides is often described as one of the most complex and problematic of the Platonic dialogues. In it a group of characters, including Parmenides, an eccentric teacher and poet from Elea, Zeno, the student and lover of Plato, and the young Socrates and Aristotle, engage in a series of conversations on some of the most abstract philosophical concepts: the nature of Forms, and the meaning of the One. Forms are the principles or sources of explanation of all the parts of the Whole in the world: earth, fire, man and even mortal qualities such as justice and prudence. The One, is the source of our knowledge of the Whole itself - the underlying principles of experience. Despite its structural complexity, the Parmenides gives us the clearest insight into the working of the mind of Socrates. It is the only surviving example of a conversation between Socrates and another philosopher. By studying this dialogue, the reader can gain some insight to the source of Socratic philosophy, and about the development of early Greek philosophy in general.

The concept of self-motion is not only fundamental in Aristotle's argument for the Prime Mover and in ancient and medieval theories of nature, but it is also central to many theories of human agency and moral responsibility. In this collection of mostly new essays, scholars of classical, Hellenistic, medieval, and early modern philosophy and science explore the question of whether or not there are such things as self-movers, and if so, what their self-motion consists in. They trace the development of the concept of self-motion from its formulation in Aristotle's metaphysics, cosmology, and philosophy of nature through two millennia of philosophical, religious, and scientific thought. This volume contains "Self-Movers" (David Furley), "Aristotle on Self-Motion" (Mary Louise Gill), "Aristotle on Perception, Appetition, and Self-Motion" (Cynthia Freeland), "Self-Movement and External Causation" (Susan Sauve Meyer), "Aristotle on the Mind's Self-Motion" (Michael Wedin), "Mind and Motion in Aristotle" (Christopher Shields), "Aristotle's Prime Mover" (Aryeh Kosman), "The Transcendence of the Prime Mover" (Lindsay Judson), "Self-Motion in Stoic Philosophy" (David Hahm), "Duns Scotus on the Reality of Self-Change" (Peter King), "Ockham, Self-Motion, and the Will" (Calvin Normore), and "Natural Motion and Its Causes: Newton on the 'Vis Insita' of Bodies" (J. E. McGuire). Originally published in 1994. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

This book explores a fundamental tension in Aristotle's metaphysics: how can an entity such as a living organisma composite generated through the imposition of form on preexisting matterhave the conceptual unity that Aristotle demands of primary substances? Mary Louise Gill bases her treatment of the problem of unity, and of Aristotle's solution, on a fresh interpretation of the relation between matter and form. Challenging the traditional understanding of Aristotelian matter, she argues that material substances are subverted by matter and maintained by form that controls the matter to serve a positive end. The unity of material substances thus involves a dynamic relation between resistant materials and directive ends.

Aristotle on Substance offers both a general account of matter, form, and substantial unity and a specific assessment of particular Aristotelian arguments. At every point, Gill engages Aristotle on his own philosophical ground through the detailed analysis of central, and often controversial, texts from the Metaphysics, Physics, On Generation and Corruption, De Anima, De Caelo, and the biological works. The result is a coherent, firmly grounded rethinking of Aristotle's central metaphysical concepts and of his struggle toward a fully consistent theory of material substances.

"Gill's and Ryan's Parmenides is, simply, superb: the Introduction, more than a hundred pages long, is transparently clear, takes the reader meticulously through the arguments, avoids perverseness, and still manages to make sense of the dialogue as a whole; there is a fine selective bibliography; and those parts of the translation I have looked at in detail suggest that it too is very good indeed." --Christopher Rowe, Phronesis

Composed in the fourth century b.c., the "Phaedrus--"a dialogue between Phaedrus and Socrates--deals ostensibly with love but develops into a wide-ranging discussion of such subjects as the pursuit of beauty, the nature of humanity, the immortality of the soul, and the attainment of truth, ending with an in-depth discussion of the principles of rhetoric. This erudite commentary, which also includes the original Greek text, is designed to help intermediate-level students of Greek read, understand, and enjoy Plato's magnificent work.""
Drawing on his extensive classroom experience and linguistic expertise, Paul Ryan offers a commentary that is both rich in detail and--in contrast to earlier, more austere commentaries on the "Phaedrus"--fully engaging."" Line by line, he explains subtle points of language, explicates difficulties of syntax, and brings out nuances of tone and meaning that students might not otherwise notice or understand. Ryan sections his commentary into units of convenient length for classroom use, with short summaries at the head of each section to orient the reader.
Never straying far from the text itself, Ryan provides useful historical glosses and annotations for the student, introducing information ranging from the architecture of the Lyceum to Athenian politics. Further historical and philosophical context is provided in the introduction by Mary Louise Gill, who outlines the issues addressed in the "Phaedrus "and situates it in relation to Plato's other dialogues.

The essays in this volume are all devoted to Plato's Theaetetus. In the first part, each of the three definitions of knowlege given in the dialogue are examined in turn. The second part then studies the various readings, interpretations and uses that were made of the Theaetetus throughout history, from Ancient times to Montaigne, constituting thus a rich and complex heritage.
