Giraldus Odonis O.F.M.: Opera Philosophica

This volume contains the first critical edition of the Logica written by Giraldus Odonis, a 14th century anti-occamist Franciscan master, who was minister general of the Order (1329-42) and died of the plague in 1349, as patriarch of Antioch. He is mainly known as the author of an influential commentary on Aristotle's Ethics (Venice, 1500). Despite the fact that the well-known medievalist Dr. Anneliese Maier regarded him as 'one of the most original and most courageous philosophers of the 14th century', most of his other works are still unedited.The three parts of Girald's Logica demonstrate his original approach to common logical and metaphysical doctrines. The third tract, on demonstrative argument, is of singular importance. Throughout his Logica, Girald's view on the relationship between logico-semantics and metaphysics come to the fore.
