The rediscovery of Aristotle in the late twelfth century led to a fresh development of logical theory, culminating in Buridan's crucial comprehensive treatment in the Treatise on Consequences. Buridan's novel treatment of the categorical syllogism laid the basis for the study of logic in succeeding centuries. This new translation offers a clear and accurate rendering of Buridan's text. It is prefaced by a substantial Introduction that outlines the work's context and explains its argument in detail. Also included is a translation of the Introduction (in French) to the 1976 edition of the Latin text by Hubert Hubien.

John Buridan was a fourteenth-century philosopher who enjoyed an enormous reputation for about two hundred years, was then totally neglected, and is now being 'rediscovered' through his relevance to contemporary work in philosophical logic. The final chapter of Buridan's Sophismata deals with problems about self-reference, and in particular with the semantic paradoxes. He offers his own distinctive solution to the well-known 'Liar Paradox' and introduces a number of other paradoxes that will be unfamiliar to most logicians. Buridan also moves on from these problems to more general questions about the nature of propositions, the criteria of their truth and falsity and the concepts of validity and knowledge. This edition of that chapter is intended to make Buridan's ideas and arguments accessible to a wider range of readers. The volume should interest many philosophers, linguists and logicians, who are increasingly finding in medieval work striking anticipations of their own concerns.
