I. Rosier (ed.); — Gosvin de Marbais, Tractatus de constructione,

Turnhout, Brepols, 1998 Paperback, LIII+112 p., 165 x 240 mm. ISBN 9789070419394. John Buridan (ca. 1300-1361) was one of the most influential philosophers of his time. During his long career at the Faculty of Arts at the University of Paris, he taught many logic courses, for which he wrote a textbook, entitled Summulae dialecticae. This work consists of nine treatises. The present volume presents a new critical edition of Buridan's Sophismata based on a collection of six manuscripts and an incunabulum. It forms part of an international project to edit the whole of John Buridan's Summulae dialecticae, the most extensive version of which consists of nine treatises (tractatus). The treatise on sophisms is the ninth treatise of the Summulae dialecticae and deals with most of the major subjects discussed by the fourteenth century logicians (signification, supposition, appellation, truth-conditions, insolubles, etc.). Although it illustrates how some of the theorems of the preceding treatises may be put to use, it can not be considered a systematic practical companion to the preceding collection of theorems. It is nevertheless one of the most important pieces among Buridan's works. Languages: Latin, English.
