The commentaries on the Ethica nova and the Ethica vetus written by some masters of the arts – presumably operating in the Paris faculty – in the first half of the thirteenth century expound in an original way the doctrine of the virtutes consuetudinales which Aristotle, at the end of the first book of his Ethica (I 13), distinguishes into the two main classes of the “moral virtues” and the “intellectual virtues”. The present paper aims at highlighting the particularly important (...) task which is assigned to the intellectual virtues in these early commentaries: joining man to God directly, through a contemplation which becomes love. The masters of the arts maintain that the moral virtues, in spite of the definition given by Aristotle (habitus a quo quis bonus est et opus eius bene reddit), are not sufficient alone to bring man to perfection, but that other more perfect virtues, namely the intellectual ones, are needed in order to make him know and love the supreme good. Having no knowledge of the sixth book of the Ethica, in which Aristotle deals in particular with the intellectual virtues, our masters know only their general description and are concerned with clarifying their relationships with the moral virtues, compared to which they appear to be sometimes really distinct and sometimes united to them in sharing the recta ratio, so much that they may constitute a double virtue. Although the masters of the arts seem to be well-informed about the teaching of the theologians – which they often cite without opposing to it, albeit stressing their own philosophical point of view –, it is significant that no reference whatsoever is made by them to the theological virtues and that they have recourse to the themes of Avicennian mysticism such as the doctrine of the two faces of the soul. Besides presenting the commentaries on the Ethica vetus from a general point of view, I will focus on the Paris commentary in Ethicam veterem (Paris BN lat. 3804A, ff. 152ra-159vb, 241ra-247vb; Paris BN lat. 3572, ff. 226ra-235ra), of which I am preparing a critical edition. The Paris commentary contains in fact a special and original discussion of the doctrine of the virtutes intellectuales. (shrink)

R.I.G Hughes offers the first detailed and accessible analysis of the Hilbert-space models used in quantum theory and explains why they are so successful.

Battin et al examined data on deaths from physician-assisted suicide in Oregon and on PAS and voluntary euthanasia in The Netherlands. This paper reviews the methodology used in their examination and questions the conclusions drawn from it—namely, that there is for the most part ‘no evidence of heightened risk’ to vulnerable people from the legalisation of PAS or VE. This critique focuses on the evidence about PAS in Oregon. It suggests that vulnerability to PAS cannot be categorised simply by reference (...) to race, gender or other socioeconomic status and that the impetus to seek PAS derives from factors, including emotional state, reactions to loss, personality type and situation and possibly to PAS contagion, all factors that apply across the social spectrum. It also argues, on the basis of official reports from the Oregon Health Department on the working of the Oregon Death with Dignity Act since 2008, that, contrary to the conclusions drawn by Battin et al, the highest resort to PAS in Oregon is among the elderly and, on the basis of research published since Battin et al reported, that there is reason to believe that some terminally ill patients in Oregon are taking their own lives with lethal drugs supplied by doctors despite having had depression at the time when they were assessed and cleared for PAS.

Posidonius was a major intellectual figure of the Hellenistic world whose interests and contribution spread over the whole intellectual field: philosophy, history, the sciences. His writings are of interest not only to philosophers and classicists, but also to historians and history of science. His work survives only in fragments. The text of these fragments, collected and edited by L. Edelstein and I. G. Kidd, was published in 1972, with a second edition in 1989. This collection, along with Vol. II The (...) Commentary by I.G. Kidd, has become established as the definitive modern edition. However, many of the fragments are extremely difficult to translate, and this volume of translations has been compiled to make this interesting material more easily accessible to scholars and students. The translations are accompanied by contextual introductions and explanatory notes where necessary. An Introduction summarises the importance of Posidonius and his work. (shrink)

The Stoics maintained that virtue was the only good; everything else, therefore, was not-good. On the other hand, regarded by itself, this huge class was not equally valueless. Vice, of course, was bad; but everything else was thought to be ‘indifferent’: wealth, health, for example; indifferent, that is, with regard to the summum bonum. Of these Intermediates, men, from human nature, had a leaning to some; these were , had value, were called , that is, preferred, and virtue itself lay (...) in choice exercised among them. (shrink)

A new constructivist approach to modeling in economics and theory of consciousness is proposed. The state of elementary object is defined as a set of its measurable consumer properties. A proprietor's refusal or consent for the offered transaction is considered as a result of elementary economic measurement. We were also able to obtain the classical interpretation of the quantum-mechanical law of addition of probabilities by introducing a number of new notions. The principle of “local equity” assumes the transaction completed (regardless (...) of the result) of the states of transaction partners are not changed in connection with the reception of new information on proposed offers or adopted decisions (consent or refusal of the transaction). However it has no relation to the paradoxes of quantum theory connected with non-local interaction of entangled states. In the economic systems the mechanism of entangling has a classical interpretation, while the quantum-mechanical formalism of the description of states appears as a result of idealization of the selection mechanism in the proprietor's consciousness.

R.I.G. Hughes presents a series of eight philosophical essays on the theoretical practices of physics. The first two essays examine these practices as they appear in physicists' treatises (e.g. Newton's Principia and Opticks ) and journal articles (by Einstein, Bohm and Pines, Aharonov and Bohm). By treating these publications as texts, Hughes casts the philosopher of science in the role of critic. This premise guides the following 6 essays which deal with various concerns of philosophy of physics such as laws, (...) disunities, models and representation, computer simulation, explanation, and the discourse of physics.

The modern state of the Pauli exclusion principle studies is discussed. The Pauli exclusion principle can be considered from two viewpoints. On the one hand, it asserts that particles with half-integer spin (fermions) are described by antisymmetric wave functions, and particles with integer spin (bosons) are described by symmetric wave functions. This is a so-called spin-statistics connection. The reasons why the spin-statistics connection exists are still unknown, see discussion in text. On the other hand, according to the Pauli exclusion principle, (...) the permutation symmetry of the total wave functions can be only of two types: symmetric or antisymmetric, all other types of permutation symmetry are forbidden; although the solutions of the Schrödinger equation may belong to any representation of the permutation group, including the multi-dimensional ones. It is demonstrated that the proofs of the Pauli exclusion principle in some textbooks on quantum mechanics are incorrect and, in general, the indistinguishability principle is insensitive to the permutation symmetry of the wave function and cannot be used as a criterion for the verification of the Pauli exclusion principle. Heuristic arguments are given in favor that the existence in nature only the one-dimensional permutation representations (symmetric and antisymmetric) are not accidental. As follows from the analysis of possible scenarios, the permission of multi-dimensional representations of the permutation group leads to contradictions with the concept of particle identity and their independence. Thus, the prohibition of the degenerate permutation states by the Pauli exclusion principle follows from the general physical assumptions underlying quantum theory. (shrink)
