Jean Buridan developed his theory of consequence within a semantical framework compatible with what we now call token-based semantics. In his Treatise on Consequences and Sophismata, Buridan showed...

This article presents an interpretation of Deleuze’s concept of difference-in-itself. I argue that this is best understood as an adption of Duns Scotus’s concept of ultimate difference. After suggesting that the influence of Scotus on Deleuze extends beyond their shared commitment to the univocity of being, I turn to briefly review Deleuze’s notion of absolute difference. I proceed from there to explain Scotus’s accounts of univocity and ultimate difference, throughout noting the many stark parallels with Deleuze. On the basis of (...) this Scotistic reading of Deleuzian difference, I then show how Deleuze’s synthesis of univocal being and difference-in-itself can be uniquely situated within the fourteenth-century Scotistic disputations on the predicability of univocal being to ultimate difference. I conclude with some suggestions on possible further connections between Deleuze and medieval metaphysics which are opened up through this association of Deleuze with Scotus and the Scotistic tradition.

The article introduces and defends Aristotelian ontological theory of the possible as that which a power is capable of bringing about. It regards this conception to be a sort of middle way between Platonic explanation based on abstracta on one hand and the possibilist theory ultimately making everything possible into actual on the other. The doctrine defended leads to the conception of necessary being. Combined with other assumptions concerning this being, there arise some interesting issues and apparent tensions to be (...) resolved. The article outlines some of the discussions related to these problems in medieval and early modern Scholasticism. (shrink)

This paper comprises two parts. The first part is an introduction to Auriol’s moderate conceptualism, as it is presented in his Commentary on Book II of the Sentences, distinction 9, question 2, article 1. The second part is an edition of the text. In the introduction, I focus on Auriol’s use of the noetic tool of connotation. My thesis, in particular, is that connotation is a necessary prerequisite to his moderate conceptu- alism. To this purpose, the first part of this (...) introduction will be devoted to a brief presentation of Auriol’s conceptualism. In the second part, Auriol’s theory of essential predication will be presented. In the third part, I will present my claim that Auriol’s theory of essential predication can only be made sense of when read against the background of his theory of connotation as applied to intellectual cognition. Finally, I will offer a collation of Auriol’s Commentary on Book II of the Sentences, dis- tinction 9, question 2, article 1, obtained by collating eight manuscripts, which hand down Auriol’s text, that is, Firenze, Biblioteca nazionale centrale, ms. Conv. Soppr. B.6.121, Firenze, ms. Conv. Soppr. A. 3.120, Napoli, Biblioteca nazionale, ms. VII.C.3, Padova, Biblioteca Antoniana, ms. 161, scaff. ix, Paris, Bibliothèque nationale de France, ms. latin 15867; Pelplin, Biblioteka Seminarium duchownego, ms. 46/85, Vaticano (Città del), Biblioteca Apostolica, ms. Borgiano 404, Vaticano (Città del), Biblioteca Apostolica, ms. Vat. lat. 942. (shrink)

I do not think scholars have thought hard enough about Scotus’s position that there are necessary moral truths over which God has no control. Just about everyone who writes on Scotus’s ethics has noted this position, but none has paid sufficient philosophical attention to it. It turns out that necessary moral truths are logically necessary (in Scotus’s sense of logical modalities), and the fact that they are logically necessary significantly alters how we should understand radical-sounding claims in Scotus to the (...) effect that God can do whatever is logically possible. Demonstrably, what Scotus means is that God can do whatever it is logically possible for God to do, and this class is rather smaller than the class of the logically possible simpliciter. (shrink)

La lógica de la Edad Media se presenta a los lógicos contemporáneos, filósofos medievalistas, historiadores y filósofos de la lógica, como un campo tan fascinante como de difícil acceso. Parece demasiado intrincado para casi cualquier investigador de estas áreas encontrar la punta del ovillo que lo conduzca a transitar una presentación ordenada e inteligible de la lógica medieval. Este libro pretende solucionar este problema. Para ello, presenta de manera ordenada y autocontenida los desarrollos lógicos de la parte técnicamente más evolucionada (...) de la lógica de la Edad Media: el siglo XIV. A diferencia de otras presentaciones no evade los hechos históricos y culturales que conforman el panorama de la época ni las cuestiones filosóficas detrás de los desarrollos lógicos, a fin de entender cabalmente las cuestiones técnicas y no desnaturalizar la propuesta medieval. Los primeros tres capítulos se abocan a cuestiones introductorias, históricas y a la genealogía de los tópicos más importantes. El cuarto capítulo está dedicado a la presentación sintáctica del lenguaje de la lógica medieval. El quinto y el sexto a la metateoría de esta lógica. El séptimo explora y presenta la semántica. Los dos últimos nos brindan una reconstrucción racional, en términos del lenguaje simbólico contemporáneo, de la lógica de finales del siglo XIV. (shrink)

Pour Jean Duns Scot, tout ce qui n’est pas contradictoire par essence peut être réalisé. Cet aspect du possible, largement documenté dans la littérature récente, s’explique par la théologie scotiste où Dieu pense tout ce dont l’essence n’est pas contradictoire et peut, par sa toute- puissance, immédiatement poser chacun de ces possibles dans l’existence. On découvre néanmoins un deuxième ordre du possible chez Scot : comme le passé est nécessaire en tant que réalisé, le critère de non-contradiction à l’existant déjà (...) réalisé s’ajoute ainsi au critère de non-contradiction de l’essence du possible à être. J’aimerais ici montrer que, pour Scot, le possible n’est pas que non-contradiction de l’essence de l’étant à être, mais que ce qui a été réalisé est aussi fonction du possible dans la mesure où il pose l’ordre à respecter quant à ce qui peut encore advenir.
