Formal dialogue systems model rule-based interaction between agents and as such have multiple applications in multi-agent systems and AI more generally. Their conceptual roots are in formal theories of natural argumentation, of which Hamblin’s formal systems of argumentation in Hamblin (Fallacies. Methuen, London, 1970, Theoria 37:130–135, 1971) are some of the earliest examples. Hamblin cites the medieval theory of obligationes as inspiration for his development of formal argumentation. In an obligatio, two agents, the Opponent and the Respondent, engage in an (...) alternating-move dialogue, where the Respondent’s actions are governed by certain rules, and the goal of the dialogue is establishing the consistency of a proposition. We implement obligationes in the formal dialogue system framework of Prakken (Knowl Eng Rev 21(2):163–188, 2006) using Dynamic Epistemic Logic (van Ditmarsch et al. in Dynamic epistemic logic, Synthese Library Series. Springer, Berlin, 2007). The result is a new type of inter-agent dialogue, for consistency-checking, and analyzing obligationes in this way also sheds light on interpretational and historical questions concerning their use and purpose in medieval academia.

This paper is a report of the conference 'Suárez’s Metaphysics. Disputationes Metaphysicae in their Historical and Systematical Context', October 1-3 2008 in Prague.

This study provides a thorough exegesis of the names of metaphysics according to the proem of the Disputationes metaphysicae by Francis Suarez. The key to its consideration lies in the simultaneous unity between this science and the names assigned to it mainly by Aristotle. Due to the scant attention devoted to this work, this study emphasizes that the epistemic unity of metaphysics is given beforehand –prior to the final consideration and determination of its proper object, which is the entity (...) insofar real entity– by the complementarity of the different perspectives each name of metaphysics denotes.

An account of the astrological controversies that arose in Renaissance Italy in the wake of Giovanni Pico della Mirandola’s _Disputationes adversus astrologiam divinatricem_, published in 1496.

Ziel dieser Kölner Habilitationsschrift ist es (S. 10), „einen Beitrag zur wissenschaftlichen Aufarbeitung der byzantinischen Adversus-Judaeos-Literatur zu leisten, wir wollen dabei das gesamte byzantinische Jahrtausend berücksichtigen …“ – „Als wichtigster Vertreter antijüdischen Gedankenguts in der byzantinischen Welt“ wurde „zwangsläufig“ (S. 11) der Dialog gewählt.

Tommaso Giannini was a prominent professor at the ferrarese Studium between sixteenth and seventeenth century. Probably influenced by Platonic sympathies nurtured by the Court and partly by the University milieu, in 1587 he published his first work titled De providentia ad sententiam Platonis et Platonicorum liber unus, which was a catalyst for his academic career. A compilative work in essence, the De providentia displays a large amount of sources always tacitly used: Marsilio Ficino, Jacques Charpentier, Giulio Serina, Stefano Tiepolo, Teofilo (...) Zimara, Bessarion, Agostino Steuco and amid the ancients Plotinus, Plutarcus, Sirianus, Proclus, Giamblicus, Apuleius, Calcidius, Ammonius, Psellus. A small place is reserved to Giovanni Pico della Mirandola and precisely to his Disputationes adversus astrologiam divinatricem. The aim of the paper is to provide a supplement of analysis of Giannini’s interest in Pico’s works considering his later writings, each one commonly identified as Disputationes Aristotelicae.

While the therapeutic effect of post-classical philosophy in antiquity has recently been recognized, Cicero and his oeuvre have been mostly ignored in that respect, because he was deemed too compilatory and eclectic. However, the Tusculanae Disputationes are just that - a philosophical therapy for the soul that pervades all five books of this work - as is brought to light in this new interpretation. German text.

De acuerdo con las D.M. de Francisco Suárez, la ciencia metafísica ha perdido su horizonte. Por esta razón el tratado del Dr. Eximio principia con un estudio de la filosofía primera donde paulatinamente se atenderán las dificultades emergentes relativas a una consideración de las ciencias especulativas. De ese modo la claridad alcanzada en derredor de la metafísica colocaría las bases necesarias para evitar –o tratar de corregir– los errores en teología sagrada por su vinculación necesaria con la filosofía primera. Asimismo, (...) el esclarecimiento del objeto adecuado de la metafísica conlleva la necesidad de evidenciar para la razón aquellos propios de las demás ciencias, configurándose así una división y relación entre ellas en sede objetiva. A su vez este panorama aparece expresado con total claridad en las D.M. I, I, 14-15 sobre el que exclusivamente se hará foco. (shrink)

Nuestro propósito se cifra en esta ocasión, en mostrar los motivos filosóficos que condujeron al Martin Heidegger a introducir la metafísica suareciana en la configuración de su ontología existenciaria. Tomaremos como hilo conductor la historia del ser y más en concreto, la de su olvido en favor del ente y que Heidegger desarrolló en diferentes escritos como un momento negativo, fundamental y previo a la exposición de su concepción de la Metafísica. En este relato dejaremos anotado, la función capital que (...) para el proyecto heideggeriano de reinterpetación de la Metafísica desempeñó, la idea de la metafísica griega y en particular de la aristotélica alcanzada por el pensador alemán. Abordaremos este problema con cierta extensión pues sostenemos que el concepto de la metafísica suareciana manejado por Heidegger está determinado por su comprensión de la Metafísica de Aristóteles. Y que se resume en su conocida interpretación onto-teológica. En último término, el peso de la reflexión heideggeriana sobre la metafísica de Suárez, recae sobre el concepto de existencia y su modo de aprehensión que es comprendido como un antecedente moderno e imperfecto del Dasein como vía de acceso al Ser.

The paper presents seven basic features of Francisco Suárez’s metaphysics. They are as follows: “Univocalization” of the concept of being and transcendental properties, “reification” of the act-potency doctrine, “ontologization” of individuality, “conceptualization” of the Scotist perspective, “existential” character of the concept of being, “epistemologization” and “methodologization” of metaphysics. Whereas the first five are indicated as remaining in the preserve of the traditional scholastic philosophy, the last two are taken as portending the methodological priority of the subjective states of affairs of (...) early modern “main-stream” philosophy.

Tout parcours est "semé d'embûches" - chacun le sait, ou à tout le moins le sent. Ce livre en est à nouveau la preuve. Non pas qu'on nous tende des pièges, mais en cela que les courses de 'sauts d'obstacles' sont toujours les plus prestigieuses, mais aussi les plus périlleuses. En réponse à Une analytique du passage (Claude-Brunier Coulin, éd.), ce volume de la plume de l'auteur reprend ainsi point par point les 'interrogations et objections' soulevées lors du colloque de (...) Chevilly-Larue (5-7 Juillet 2014), tout en proposant un véritable 'itinéraire' retraçant sa propre trajectoire. La source franciscaine, l'humanité commune, le sens de la catholicité, la racine ignacienne, l'héritage péguyste, le rapport à la finitude, le problème du surnaturel, le statut de l'apologétique, la relation au corps, le sens de la voix, la traversée du chaos, la question de la limite, le statut de l'Ecriture, le sens du style..., sont autant de thèmes et de questions abordées dans le présent essai. Faisant de la lutte de Jacob avec l'ange la figure de proue de cette grande traversée - "Je ne te lâcherai pas que tu m'aies béni" (Gn 32, 27) -, cet ouvrage accomplit le 'cycle méthodologique' initié par Passer le Rubicon (Lessius, 2013), relayé par Le combat amoureux (Hermann, 2014), et achevé par le Parcours d'embûches (Editions franciscaines, 2016).
