This volume reconstructs Martin Heidegger's lecture course at the University of Marburg in the winter semester of 1924-25, which was devoted to an interpretation of Plato and Aristotle. Published for the first time in German in 1992 as volume 19 of Heidegger's Collected Works, it is a major text not only because of its intrinsic importance as an interpretation of the Greek thinkers, but also because of its close, complementary relationship to Being and Time, composed in the same period. In Plato's Sophist, Heidegger approaches Plato through Aristotle, devoting the first part of the lectures to an extended commentary on Book VI of the Nichomachean Ethics. In a line-by-line interpretation of Plato's later dialogue, the Sophist, Heidegger then takes up the relation of Being and non-being, the ontological problematic that forms the essential link between Greek philosophy and Heidegger's thought.

Plato's later dialogue, the Sophist, is deemed one of the greatest works in the history of philosophy, but scholars have been shy of confronting the central problem of the dialogue. For Plato, defining the sophist is the basic philosophical problem: any inquirer must face the 'sophist within us' in order to secure the very possibility of dialogue, and of philosophy, against sophistic counterattack. Examining the connection between the large and difficult philosophical issues discussed in the Sophist (appearance, image, falsehood, and 'what is not') in relation to the basic problem of defining the sophist, Dr Notomi shows how Plato struggles with and solves all these problems in a single line of inquiry. His interpretation of the whole dialogue finally reveals how the philosopher should differ from the sophist.

Marina McCoy explores Plato's treatment of the rhetoric of philosophers and sophists.

This book consists of a selection of papers which throw new light on old problems in one of Plato's most difficult dialogues. The papers included fall into three broad categories: a) those dealing directly with the ostensible aim of the dialogue, the various definitions of a sophist from different perspectives (T. Robinson, F. Casadesús, J. Monserrat-P. Sandoval, A. Bernabé, M. Narcy and K. Dorter ; b) a number which tackle a specific question brought up in the dialogue, and that is, how Plato relates to Heraclitus and to Parmenides in the matter of his understanding of being and non-being (E. Hülsz, D. O'Brien, B. Bossi, P. Mesquita and N. Cordero) ; and c) those discussing various other broad issues brought to the fore in the dialogue, such as the 'greatest kinds', true and false statement, difference and mimesis (F. Fronterotta, J. de Garay, D. Ambuel and L. Palumbo).The variety of schools and backgrounds of the authors makes this book unique as a tool for the appreciation of the different approaches possible to well-known hermeneutical problems.

"Sophist" is one of Plato's dialogues, believed to have been written in the middle period of his philosophical career, around 380 BCE. In this dialogue, Plato explores the nature of sophistry, the art of persuasion, and the distinction between true knowledge and mere opinion. The dialogue takes place between Socrates and several interlocutors, including a Visitor from Elea and a young philosopher named Theaetetus. The conversation revolves around the question of whether or not it is possible to define what a sophist is, and if so, how to distinguish between sophists and philosophers. The central theme of "Sophist" is the examination of the nature of reality and the challenge of distinguishing between appearance and reality. The characters engage in a dialectical inquiry, attempting to define the essence of sophistry and to differentiate it from genuine philosophical inquiry. Plato uses the dialogue form to present various arguments and counterarguments, illustrating the Socratic method of inquiry and philosophical investigation. Through logical analysis and rigorous questioning, Socrates and his interlocutors explore the complexities of language, knowledge, and ontology. Overall, "Sophist" is a profound philosophical work that delves into fundamental questions about truth, knowledge, and the nature of reality. It is a challenging and thought-provoking dialogue that continues to stimulate scholarly debate and philosophical inquiry to this day.

Of all Plato’s dialogues, the Parmenides is notoriously the most difficult to interpret. Scholars of all periods have disagreed about its aims and subject matter. The interpretations have ranged from reading the dialogue as an introduction to the whole of Platonic metaphysics to seeing it as a collection of sophisticated tricks, or even as an elaborate joke. This work presents an illuminating new translation of the dialogue together with an extensive introduction and running commentary, giving a unified explanation of the Parmenides and integrating it firmly within the context of Plato's metaphysics and methodology. Scolnicov shows that in the Parmenides Plato addresses the most serious challenge to his own philosophy: the monism of Parmenides and the Eleatics. In addition to providing a serious rebuttal to Parmenides, Plato here re-formulates his own theory of forms and participation, arguments that are central to the whole of Platonic thought, and provides these concepts with a rigorous logical and philosophical foundation. In Scolnicov's analysis, the Parmenides emerges as an extension of ideas from Plato's middle dialogues and as an opening to the later dialogues. Scolnicov’s analysis is crisp and lucid, offering a persuasive approach to a complicated dialogue. This translation follows the Greek closely, and the commentary affords the Greekless reader a clear understanding of how Scolnicov’s interpretation emerges from the text. This volume will provide a valuable introduction and framework for understanding a dialogue that continues to generate lively discussion today.

Heidegger’s philosophy has an extraordinarily complex relationship to Plato. Heidegger sees Plato as the founder of that Western metaphysics which he claims should be overcome. However, his interpretation of Plato, upon which his reconstruction of the history of philosophy rests, is anything but incontestable from a philological point of view, and has generated much criticism. This criticism, however, has been hampered by the fact that the only example in Heidegger’s work of a detailed analysis of a Platonic dialogue, namely the Lectures on Plato’s Sophist held in Marburg in 1924–25, remained unpublished until 1992. Thus, only in the last twenty years have scholars been able to develop a more nuanced understanding of Heidegger’s interpretation of Plato. Even then, however, the focus has been primarily on the importance of the lectures for Heidegger’s own thought. The possible impact of Heidegger’s interpretation on the study of Platonic philosophy itself has been neglected. This volume, therefore, offers a critical re-evaluation of Heidegger as an interpreter of Plato.
