This paper deals with the axiomatizability problem for the matrix-based logics RMQ − and RMQ *. We present a Hilbert-style axiom system for RMQ −, and a quasi-axiomatization based on it for RMQ *. We further compare these logics to different well-known modal logics, and assess its status as relevance logics.

We introduce a new understanding of deontic modals that we callobligations as weakest permissions. We argue for its philosophical plausibility, study its expressive power in neighborhood models, provide a complete Hilbert-style axiom system for it and show that it can be extended and applied to practical norms in decision and game theory.

In Meyer’s promising account [7] deontic logic is reduced to a dynamic logic. Meyer claims that with his account “we get rid of most (if not all) of the nasty paradoxes that have plagued traditional deontic logic.” But as was shown by van der Meyden in [4], Meyer’s logic also contains a paradoxical formula. In this paper we will show that another paradox can be proven, one which also effects Meyer’s “solution” to contrary to duty obligations and his logic in (...) general. (shrink)

We develop an exact truthmaker semantics for permission and obligation. The idea is that with every singular act, we associate a sphere of permissions and a sphere of requirements: the acts that are rendered permissible and the acts that are rendered required by the act. We propose the following clauses for permissions and obligations: -/- - a singular act is an exact truthmaker of Pφ iff every exact truthmaker of φ is in the sphere of permissibility of the act, and (...) -/- - a singular act is an exact truthmaker of Oφ iff some exact truthmaker of φ is in the sphere of requirements of the act. -/- We show that this semantics is hyperintensional, and that it can deal with some of the so-called paradoxes of deontic logic in a natural way. Finally, we give a sound and complete axiomatization of the semantics. (shrink)

In this contribution the socalled Meno-Problem will be discussed. With respect to theories the problem is the following question: Why is it epistemologically more valuable to know a true theory than to simply believe it? A classical answer in reabilist accounts to this problem refers to the value of the operation which is used for gathering knowledge. But there is a gap in the argumentation as far as one is not allowed to derive from this assumption the conclusion that also (...) the result of the operation is valuable. We are going to show a difference between true theories which are just believed and theories which are also known to be true. This difference seems to allow one to close the mentioned gap. (shrink)

The SOPhiA conferences are intended to give young predoctoral philosophers the possibility to actively attend a professional conference, to tackle current, as well as classical, philosophical problems, and to discuss their own approaches with promising students from many dierent countries as well as with wellestablished experts. We are firmly convinced that this is a natural and necessary step for promoting the next generation of analytic philosophers and thus, strengthening analytic philosophy in general. Because we believe that the methods of analytic (...) philosophy can be fruitfully applied to all areas of philosophy, the SOPhiA conferences do not have a thematic focus; this is also reflected by the fact that the talks given at SOPhiA 2011 covered all areas of philosophy.

© by Journal of the History of Ideas. Federico Commandino can be considered the personification of the renaissance of mathematics in sixteenth-century Italy. Previous scholars have generally reduced the philosophy of mathematics developed by Commandino in the preface to his translation of Euclid’s Elements to a superficial synthesis of Neoplatonic and Aristotelian elements. Until now, no attention has been paid to Commandino’s use of the sixth-century commentary on Aristotle’s De Anima by John Philoponus. In his article I will argue that, (...) in depicting imagination as a mental drawing board for geometrical figures, Commandino directly relies on Philoponus’s concept of mathematical imagination.

This book addresses the theme of global sustainable development across two dimensions.First it introduces its progress and prospects in both rich and poor countries. It then outlines the major trends that will in practice influence the direction of sustainable development into the next century. It encompasses an understanding of sustainable development as both a theoretical framework for thinking about how to deal with human needs and environmental limits on the one hand, and a more material understanding of it as a (...) set of practices, on the other.The book is written by a group of internationally-recognised experts in the field, and is distinctive in offering a variety of philosophical and ethical reflections on sustainable development. Core issues covered include economic growth, poverty reduction, future generations, technology, population and diversity, making it an ideal text for students.Key Features: The only available text to introduce the philosophical and ethical issues surrounding sustainable developmentContributors are internationally-renowned experts in the field and include activists and policy makers, as well as academicsCore areas include global equality, technology, women and populationAn ideal course textbook for Politics, Philosophy and International Relations student.

The ethical challenges of caring for the chronically ill are of increasing concern to nurses as they attempt to create humanitarian environments for long-term care. This article suggests two ethical perspectives to guide the agenda of the nursing profession to achieve social change in the care of the chronically ill and aging. First, a reemphasis on the public duties of the professions is recommended which extends beyond serving the interests of the nursing profession to recognizing the need to serve the (...) common good. Second, the limitations of the autonomy paradigm are explored and the foundation for the development of a new moral paradigm is analyzed in terms of its' potential usefulness in addressing ethical problems of chronic illness. Several initiatives that nursing must undertake to facilitate the emergence of this paradigm are proposed. (shrink)

Filosofische ponering van de subjectiviteit van elke interpretatie.

Recent developments such as the 'new wars' or the growing privatisation of warfare, and the ever more sophisticated military technology, present the military with difficult ethical challenges. This book offers a selection of the best scholarly articles on military ethics published in recent decades. It gives a hearing to all the main ethical approaches to war: just war theory, consequentialism, and pacifism. Part I includes essays on justice of war (jus ad bellum), focussing on defence against aggression and humanitarian armed (...) intervention, but also addressing topics such as conscientious objection and the relation of patriotism to war. Articles in Part II deal with the central problems of justice in war (jus in bello): civilian immunity and 'collateral damage' to civilian life and property. Essays in Part III look into the moral issues facing the military as a profession, such as the civil - military relations, the responsibilities of officers to their soldiers and to their military superiors, and the status and responsibilities of prisoners of war.

'Uncertainty and chance' is a subject with a broad span, in that there is no academic discipline or walk of life that is not beset by uncertainty and chance. In this book a range of approaches is represented by authors from varied disciplines: natural sciences, mathematics, social sciences and medical sciences. At one extreme, this volume is concerned with the foundations of probability. At the other extreme, we have scholars who acknowledge the concept of chance and uncertainty but do not (...) cope with it by means of systematic measurement or quantative analysis. (shrink)
