This volume pays homage to the historian of logic Angel d’Ors (1951-2012), by bringing together a set of studies that together illuminate the complex historical development of logic and semantics. Two main traditions, Aristotelian and terminist, are showcased to demonstrate the changes and confrontations that constitute this history, and a number of different authors and texts, from the Boethian reception of Aristotle to the post-medieval terminism, are discussed.
Special topics dealt with include the medieval reception of ancient logic; technical tools for the medieval analysis of language; the medieval theory of consequence; the medieval practice of disputation and sophisms; and the post-medieval refinement of the terminist tools.
Contributors are E.J. Ashworth, Allan Bäck, María Cerezo, Sten Ebbesen, José Miguel Gambra, C.H. Kneepkens, Kalvin Normore, Angel d’Ors, Paloma Pérez-Ilzarbe, Stephen Read, Joke Spruyt, Luisa Valente, and Mikko Yrjönsuuri.
