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.
