The second volume of Jonathan Barnes' papers on ancient philosophy contains twenty-seven pieces under the broad heading of Logic. The essays were written over a period of some forty years. Some of them were published in obscure places (and two or three of them in a foreign language). The French essays have been done into English; and all the essays have been retouched, and a few of them substantially revised. The first three essays in the volume are of a general nature, being concerned with ancient views on the status of logic--and with the distinction between formal and material inferences. The next nine items deal with different aspects of Aristotelian logic--the copula, negation, the categories, homonymy, and the principle of contradiction. Then come three papers about the connection (or lack of connection) between Aristotelian logic and Stoic logic. Two of the pieces discuss Theophrastus' theory of 'hypothetical' syllogisms. After that, things run more or less chronologically--a short notice on the Dialecticians, three essays on aspects of Stoic logic, a pair of papers on ancient theories of meaning, items on adverbs and connectors, on Philoponus and Boethius, and on an anonymous tract written in the autumn of 1007 AD. All in all, there is matter to divert scholars and students of ancient philosophy.

Proof, Knowledge, and Scepticism is the third volume of Jonathan Barnes' papers on ancient philosophy. It contains twenty-two pieces on epistemological matters, some of them revised, and one or two which appear for the first time in English. Anyone with an interest in ancient philosophy will find them enriching and amusing.

The late Mario Mignucci was one of the most authoritative, original, and influential scholars in the area of ancient philosophy, especially ancient logic. Collected here for the first time are sixteen of his most important essays on Ancient Logic, Language, and Metaphysics. These essays show a perceptive historian and a skillful logician philosophically engaged with issues that are still at the very heart of history and philosophy of logic, such as the nature of predication, identity, and modality. As well as essays found in disparate publications, often not easily available online, the volume includes an article on Plato and the relatives translated into English for the first time and an unpublished paper on De interpretatione 7. Mignucci thinks rigorously and writes clearly. He brings the deep knowledge of a scholar and the precision of a logician to bear on some of the trickiest topics in ancient philosophy. This collection deserves the close attention of anyone concerned with logic, language, and metaphysics, whether in ancient or contemporary philosophy.

Method and Metaphysics presents twenty-six essays in ancient philosophy by Jonathan Barnes, one of the most admired and influential scholars of his generation. The essays span four decades of his career, and are drawn from a wide variety of sources: many of them will be relatively unknown even to specialists in ancient philosophy. Several essays are now translated from the original French and made available in English for the first time; others have been substantially revised for republication here. The volume opens with eight essays about the interpretation of ancient philosophical texts, and about the relationship between philosophy and its history. The next five essays examine the methods of ancient philosophers. The third section comprises thirteen essays about metaphysical topics, from the Presocratics to the late Platonists. This collection will be a rich feast for students and scholars of ancient philosophy.

The essays in this volume treat a wide variety of fundamental topics and problems in ancient Greek philosophy. The scope of the section on pre-Socratic thought ranges over the views which these thinkers have on such areas of concern as religion, natural philosophy and science, cosmic periods, the nature of elements, theory of names, the concept of plurality, and the philosophy of mind. The essays dealing with the Platonic dialogues examine with unusual care a great number of central themes and discuss them in considerable depth: problems in language and logic, myth, reason, hypothesis, eros, friendship, reason, morality, society, art, the nature of soul, and immortality. In addition, they offer fresh discussions on a number of basic morphological, methodological, and philological issues related to philosophical arguments and introduce new aspects for a critical reexamination of controversies surrounding the doctrines and the authenticity of certain Platonic works. The essays on the philosophy of Aristotle are closely reasoned analyses of such basic themes as the universality of the sensible, the nature of kinesis, the problem of future contingencies, the meaning of qualitative change, the doctrine of phantasia, the essence of intelligence, and the metaphysical foundations for the ethical life. The essays on post-Aristotelian developments in ancient philosophy offer challenging and well-documented discussions on topics in the history of ancient logic, categorical thought, the ethical doctrines of ancient Scepticism, epistemological issues in the physical theory of the Epicureans, and basic concepts in the metaphysics of the neo-platonists.

This Companion provides a comprehensive guide to ancient logic. The first part charts its chronological development, focussing especially on the Greek tradition, and discusses its two main systems: Aristotle's logic of terms and the Stoic logic of propositions. The second part explores the key concepts at the heart of the ancient logical systems: truth, definition, terms, propositions, syllogisms, demonstrations, modality and fallacy. The systematic discussion of these concepts allows the reader to engage with some specific logical and exegetical issues and to appreciate their transformations across different philosophical traditions. The intersections between logic, mathematics and rhetoric are also explored. The third part of the volume discusses the reception and influence of ancient logic in the history of philosophy and its significance for philosophy in our own times. Comprehensive coverage, chapters by leading international scholars and a critical overview of the recent literature in the field will make this volume essential for students and scholars of ancient logic.

Mantissa is the fourth (and last) volume of Jonathan Barnes' collected essays on ancient philosophy. It contains twenty-three papers on a diverse range of subjects, from the size of the sun to Plato and Aristotle in Victorian Oxford. One of the essays is new, and the others are all retouched or revised; six are newly translated into English.
