This paper provides a philosophical analysis and a new edition of an anonymous Epitome of John Dumbleton’s solution to the semantic paradoxes. The first part of this paper briefly presents Dumbleton’s cassationist solution to the semantic paradoxes, which the English philosopher proposes in his Summa Logicae, written in the 1330s–40s. The second part investigates the solution to various types of insolubles proposed by the anonymous author of the Epitome. The third part provides a new critical edition of the Latin text (...) – a first edition was edited by Bottin in 1978 – and an English translation. (shrink)

By a comparison between Maxwell's electrodynamics classically interpreted (MT) and relativistic electrodynamics (RED), this paper discusses whether the “asymmetries” in MT mentioned by A. Einstein in his 1905 relativity paper are only of a conceptual nature or rather involve specific empirical claims. It is shown that in fact MT predicts strongly asymmetric behaviour for very simple interactions, and an analysis is made of the extent of the “symmetry” achieved by means of relativistic postulates. A “low” velocity experiment is suggested which (...) could provide another test of the accuracy of RED with respect to MT. (shrink)

Paolo Beni da Gubbio (1553-1625) has been studied almost exclusively for his literary and rhetorical production. However, he finds an important place among the scholars of the Renaissance who developed a novel reading of Plato as an alternative to the predominant exegesis of Ficino and his followers. His writings represent a prime example of the interplay between exegetical discussions (both of literary and philosophical texts) and the emerging sciences. In the unpublished part of his commentary on Plato’s "Timaeus", Beni discusses (...) Platonic natural philosophy – cosmology in particular – in the light of the interpretations of other authors as well as the new scientific theories, mostly in relation to the Paduan scientific circles. From Galileo’s correspondence with Giovan Battista Manso, we know that Beni weas well-informed about Galileo’s astronomical observations and discoveries at the beginning of 1610, which were soon published thereafter in the "Sidereus Nuncius". Further, we have information concerning Beni’s active role in the circulation of these observations. We wish to cast new light on the reception of these novelties by an advocate of the classical tradition such as Beni. Beni’s praise of the new discoveries is testified by his unedited commentary to the Ciceronian "Dream of Scipio" (1610-15), in which he criticizes the Aristiotelian cosmological model, referring to the newly invented telescope and referring to Galileo’s astronomical observations. Echoes of new scientific and cosmological theories appear also in Beni’s commentaries on Tasso’s "Delivered Jerusalem". (shrink)

The Aristotelian commentaries by Petrus de Rivo, still unedited, represent a valuable instrument for our understanding of the major trends in the teaching of Aristotle at the fifteenth-century Faculty of Arts at Louvain. We published a preliminary survey of the manuscript material in last year’s issue of this journal, together with an account of the status quaestionis concerning Peter’s biography, works and the historical context of his thought. In the present article, we consider more closely a selection of his commentaries (...) on logic and natural philosophy. First, we offer an overview of Peter’s division of the sciences as expressed in his tractatus prohemiales, particularly those introducing his commentaries on Porphyry’s Isagoge and Aristotle’s Physics. Next, we considers Peter’s explanation of De interpretatione chapter 9, and his exposition of specific parts of Aristotle’s Physics and De anima. (shrink)

Recent years have yielded many discussions on how to endow autonomous agents with the ability to make ethical decisions, and the need for explicit ethical reasoning and transparency is a persistent theme in this literature. We present a modular and transparent approach to equip autonomous agents with the ability to comply with ethical prescriptions, while still enacting pre-learned optimal behaviour. Our approach relies on a normative supervisor module, that integrates a theorem prover for defeasible deontic logic within the control loop (...) of a reinforcement learning agent. The supervisor operates as both an event recorder and an on-the-fly compliance checker w.r.t. an external norm base. We successfully evaluated our approach with several tests using variations of the game Pac-Man, subject to a variety of “ethical” constraints. (shrink)

This volume focuses on the interactions between mathematics, physics, biology and neuroscience by exploring new geometrical and topological modeling in these fields. Among the highlights are the central roles played by multilevel and scale-change approaches in these disciplines. The integration of mathematics with physics, molecular and cell biology, and the neurosciences, will constitute the new frontier and challenge for 21st century science, where breakthroughs are more likely to span across traditional disciplines.

Paul of Venice joined the Austin Friars at an early age and was sent by them from Padua to study at Oxford in 1390. When he returned, full of ideas and laden with books, he began his prodigious writing career with several books on logic, including the Logica Magna, which runs to some half a million words. The current volume contains the final treatise, on insolubles - that is, logical paradoxes. After surveying fifteen previous solutions, Paul develops his own, based (...) on the idea that such propositions falsify themselves. Besides a critical edition of the Latin text, the volume also contains an English translation, a detailed commentary, excerpts from two other logical works of Paul, and a substantial introduction. The introduction describes the fourteenth-century background to Paul's treatise; it also gives a detailed rebuttal of a recent claim that the Logica Magna is not by Paul because its content clashes with genuine works of his. All in all, the volume greatly enhances our understanding of the development of logic, in particular of the semantics of propositions, during a crucial century in its history. (shrink)

This volume contains the first publication in book form of an English translation of Thomas Aquinas's controversial disputed question De unione Verbi incarnati. This disputed question is a remarkable portal into the Angelic Doctor's theology of the hypostatic union, which is recognized as an area in which Aquinas forged some of his most original and penetrating articulations of the Christian faith. In the De unione Verbi incarnati Aquinas presents in five articles material that occupies more than eighteen questions in the (...) third part of the Summa theologiae. The attribution of an esse secundarium to Christ, in the fourth article of the De unione, has been the object of intense debate, for it seems to contradict the account of the Summa. In addition to Professor Nutt's English translation, the volume includes the critical Latin text published by Barbara Bartocci, Klaus Obenauer, and Walter Senner, as well as a substantial introduction. Professor Nutt's introduction carefully unfolds the historical background, technical concepts, sources, and speculative claims needed for understanding the breadth of the biblical and metaphysical contemplation represented in this work; it also includes a detailed exploration of the debate over the fourth article.
