This paper shows that non-normal modal logics can be simulated by certain polymodal normal logics and that polymodal normal logics can be simulated by monomodal (normal) logics. Many properties of logics are shown to be reflected and preserved by such simulations. As a consequence many old and new results in modal logic can be derived in a straightforward way, sheding new light on the power of normal monomodal logic.

This paper investigates (modal) extensions of Heyting-Brouwer logic, i.e., the logic which results when the dual of implication (alias coimplication) is added to the language of intuitionistic logic. We first develop matrix as well as Kripke style semantics for those logics. Then, by extending the Gö;del-embedding of intuitionistic logic into S4, it is shown that all (modal) extensions of Heyting-Brouwer logic can be embedded into tense logics (with additional modal operators). An extension of the Blok-Esakia-Theorem is proved for this embedding.

La nomination des phénomènes sociaux par les spécialistes cherche à les débarrasser des contenus moraux ou idéologiques que véhiculent les termes courants et vise leur objectivation. L’exercice est difficile, car, bien souvent, les nouveaux termes proposés peuvent générer des interprétations qui trahissent les intentions de leurs auteurs. Les glissements sont encore plus importants lorsque ces termes sont repris et légitimés par les institutions. L’auteur prend pour exemple deux termes, celui de familles monoparentales et celui d’hébergement alterné. Il analyse les connotations (...) et les dénégations symboliques dont ces deux termes sont porteurs et montre l’importance du pouvoir des mots. (shrink)

Scientific breakthroughs rarely yield the potential to engage a foundational ethical question. Recent studies on direct reprogramming of human skin cells reported by the Yamanaka lab in Japan and the Thomson lab in Wisconsin suggest that scientists may have crossed both a scientific and an ethical threshold. The fascinating science of direct nuclear reprogramming highlights empirical data that may clarify the ontological status of cellular activity in the early stages of what could become a human fetus and justify ethical options (...) for research in this controversial field. The ontological and ethical implications that accrue here are connected with the biological or natural potentiality of these cells. (shrink)

Demonstrative noun phrases (e.g., that guy , this ) are of interest to philosophers of language and semanticists because they are sensitive to demonstrations or speaker intentions. The interpretation of a demonstrative therefore sheds light on the role of the context in natural language semantics. This survey reviews two types of approaches to demonstratives: Kaplan's direct reference treatment of demonstratives and other indexicals, and recent challenges to Kaplan's approach that focus on less obviously context-sensitive uses of demonstratives. The survey then (...) covers selected research on demonstratives in linguistics. This research offers new empirical puzzles and contrasting theoretical approaches to demonstratives. (shrink)

Sometimes, it is difficult to know what someone means. Sometimes, it merely appears to be difficult. Consider this masterpiece of philosophical hermeneutics from a P. G. Wodehouse short story: “Jeeves,” I said. “A rummy communication has arrived. From Mr. Glossop.” “Indeed, sir?” “I will read it to you. Handed in at Upper Bleaching. Message runs as follows: ‘When you come tomorrow, bring my football boots. Also, if humanly possible, Irish water-spaniel. Urgent. Regards. Tuppy.’.

In “Rothbard as a philosopher” Edward Feser harshly criticises the philosophical abilities of Murray Rothbard. According to Feser, Rothbard seems unable to produce arguments that don’t commit obvious fallacies or produces arguments that fail to address certain obvious objections. His criticism centres on what he regards as Rothbard’s principal argument for the thesis of self-ownership. In this paper, I attempt to show that Feser’s criticism fails of its purpose and that Rothbard is very far from being the epitome of philosophical (...) ineptitude that Feser takes him to be.

Written by one of the most important founding figures of Western philosophy, Aristotle’s _Nicomachean Ethics_ represents a critical point in the study of ethics which has influenced the direction of modern philosophy. The _Routledge Guidebook to Aristotle’s Nicomachean Ethics_ introduces the major themes in Aristotle’s great book and acts as a companion for reading this key work, examining: The context of Aristotle’s work and the background to his writing Each separate part of the text in relation to its goals, meanings (...) and impact The reception the book received when first seen by the world The relevance of Aristotle’s work to modern philosophy, its legacy and influence. With further reading included throughout, this text is essential reading for all students of philosophy, and all those wishing to get to grips with this classic work. (shrink)

It is known that even seemingly small fragments of the first-order temporal logic over the natural numbers are not recursively enumerable. In this paper we show that the monodic fragment is an exception by constructing its finite Hilbert-style axiomatization. We also show that the monodic fragment with equality is not recursively axiomatizable.

This article assumes that the key element in Relativism is the denial of any comparability between different moral codes. Each system of morality is, according to the relativist, defined internally to any given culture, as parallels with examples in sport might illustrate, and as two key examples from recent moral disputes amply show. While classical writers such as Hume and Bentham, each in his way a kind of utilitarian, certainly intended to be absolutist, it might nevertheless be argued that they (...) left the way open to relativism despite their intentions. The absolutist needs to establish a common moral standard of some kind which can be used as a standard of comparison between apparently different moral codes. Hume's assumption that we share the disposition to sympathy with others seems far too optimistic; and Bentham's attempt to be scientific presupposes a shared view both of values and of the canons of moral reasoning; but there is arguably no such shared view. Might some version of Aristotelianism be a more promising approach? The article ends with an ariswer to this question. /// O presente artigo parte do pressuposto de que o elemento-chave do Relativismo é a negação de toda e qualquer comparabilidade entre diferentes códigos morais. Cada sistema de moralidade é, de acordo com o relativista, deftnido internamente nos termos de cada cultura determinada, tal como se pode ilustrar com exemplos do mundo do desporto, e dois exemplos tirados da discussão moral mais recente amplamente demonstram. Enquanto que escritores clássicos tais como David Hume e Jeremy Bentham, cada um deles utilitarista à sua maneira, pretendiam certamente ser absolutistas, a verdade é que, argumenta o autor do artigo, ambos deixaram, apesar das suas intenções, o caminho aberto ao relativismo. O absolutista necessita de alguma forma de estabelecer um padrão moral comum que possa ser usado como termo de comparação entre códigos morais aparentemente diferenciados. O pressuposto de Hume de que nós partilhamos uma inclinação para a simpatia em relação a outros seres humanos parece demasiado optimista; por seu lado, a tentativa de Bentham de corresponder às expectativas da ciência pressupõem, por seu lado, uma visdo comum dos valores e dos cânones do raciocínio moral. O problema, porém, é que se pode demonstrar não existir uma tal visão comum. Assim, pergunta o autor do artigo, não será de considerar uma certa versão do Aristotelismo como uma abordagem mais promissora? A resposta a esta questão constitui a parte final do artigo. (shrink)

Selon la façon dont on l’envisage et l’origine du regard qui se pose sur elle, l’autorité ne paraît pas représenter la même chose. Pour certains elle est l’expression d’un principe abstrait, atemporel, relatif au jeu des places qu’organisent les rapports sociaux, en l’occurrence les places spécifiques qu’occupent les parents par rapport à l’enfant. Pourtant, pour d’autres approches, notamment les approches psychanalytiques, l’autorité n’est pas un principe neutre, elle a un sexe, de préférence masculin. Que peut-on dire d’une telle affirmation à (...) notre époque de reconfiguration des relations non seulement entre les sexes mais aussi entre les générations, et plus globalement de l’ensemble des relations privées, si ce n’est des rapports entre le public et le privé? Je m’essaie ici à une analyse sociologique, alimentée de références psychologiques et historiques, de la signification de cette question et des réponses qu’il est possible de lui apporter. (shrink)

Tense logics formulated in the bimodal propositional language are investigated with respect to Kripke-completeness (completeness) and decidability. It is proved that all minimal tense extensions of modal logics of finite width (in the sense of K. Kine) as well as all minimal tense extensions of cofinal subframe logics (in the sense of M. Zakharyaschev) are complete. The decidability of all finitely axiomatizable minimal tense extensions of cofinal subframe logics is shown. A number of variations and extensions of these results are (...) also presented. (shrink)

This article offers a new theory about how using lotteries to distribute scarce benefits satisfies beneficiaries' claims. In the first section of the article I criticize John Broome's view and on the basis of these criticisms set out four desiderata for a philosophically adequate account of claim satisfaction by lottery. In section II I propose and defend a new view called the dual structure view, so called because it posits that claimants have two types of claims in the relevant scarce (...) benefit distribution cases under discussion. This view meets all the desiderata set out in section I. Section III draws out the practical implications of my view for a variety of temporally extended cases, including the distribution of corneas to patients who have suffered corneal degeneration.

Based on the results of [11] this paper delivers uniform algorithms for deciding whether a finitely axiomatizable tense logic has the finite model property, is complete with respect to Kripke semantics, is strongly complete with respect to Kripke semantics, is d-persistent, is r-persistent.It is also proved that a tense logic is strongly complete iff the corresponding variety of bimodal algebras is complex, and that a tense logic is d-persistent iff it is complete and its Kripke frames form a first order (...) definable class. From this we obtain many natural non-d-persistent tense logics whose corresponding varieties of bimodal algebras are complex. (shrink)

The relationship between the ethical standards for the governance of clinical trials and market forces can be complex and problematic. This article uses India as a case study to explore this nexus. From the mid-2000s, India became a popular destination for foreign-sponsored clinical trials. The Indian government had sought to both attract clinical trials and ensure these would be run in line with internationally accepted ethical norms. Reports of controversial medical research, however, triggered debate about the robustness and suitability of (...) India's regulatory system. In response to civil society pressure and interventions by the Supreme Court, the Indian government proposed additional measures aimed at strengthening protections for clinical trial participants. Whilst the reforms can be seen as a victory for human rights activists, they have also been criticised as being overly burdensome for sponsors. Indeed, their announcement prompted an exodus of clinical trials from India. Fearful of losing business to ‘rival’ countries, the Indian government is revisiting some of its proposals. The Indian example suggests that research ethics frameworks and national policies for economic development are increasingly intertwined. Host countries are in theory free to improve the lot of research participants, but doing so may make them appear less attractive to foreign sponsors, who can simply shift their activities to more industry-friendly jurisdictions. Although these economic pressures are unlikely to lead to a regulatory ‘race to the bottom’, they may limit host countries' ability to enact socially desirable reforms. (shrink)

I begin with an anecdote. While a senior at a small liberal arts college, I participated in a year-long senior seminar on evolution. The central questions were how we come to be human and, more basically, what it means to be human. Units were taught from the perspectives of biology, various traditions of philosophy, theology, education, history, and world literature. Faculty were drawn from across the curriculum, each taking units and assigning readings from their discipline that addressed our central questions (...) from an evolutionary perspective. Importantly, the faculty leading seminar discussions also attended each session, so that every meeting possessed the possibility of full-scale intellectual battle not only... (shrink)

Certains ont proclamé la " fin de l'Histoire ". Ne serait-ce pas plutôt celle de la philosophie politique moderne qu'il conviendrait de guetter? Depuis cinq siècles, en effet, l'action politique a eu pour objet l'institution et la consolidation de la souveraineté, tandis que la philosophie politique structurait ses principes de gouvernement à partir de ce concept : penser la politique c'était penser la souveraineté. Or la souveraineté, née en Europe, forgée à travers les guerres qui donnèrent aux peuples le sentiment (...) de leur particularité, s'y achève sous nos yeux, en une Union des peuples fondée désormais sur la paix, à la suite d'un génocide suicidaire. Pour penser l'achèvement, la philosophie politique ne saurait plus se contenter de répéter ses affirmations communes sur la volonté du peuple, l'indivisibilité de la république, la dictature du prolétariat et les droits de l'homme. Aucune n'a pu fonder l'existence libre de la multitude : elles ont soit révélé dans l'histoire leur absolue contradiction en allant, parfois, jusqu'au crime, soit permis d'ouvrir le chemin de la vie libre sans être capables, cependant, de le tracer jusqu'au bout. Ces catégories ressortissent à un monde et à sa fable que les temps présents abandonnent au passé. Le problème constitutif de la philosophie politique - les conditions de la vie libre - n'a pas disparu pour autant, mais la solution nouvelle est à inventer. Une double tâche s'impose désormais : montrer en quoi la souveraineté est achevée et ce que cela signifie, jusque dans les chemins divergents qu'empruntent l'Europe et les Etats-Unis ; formuler des propositions sérieuses capables d'orienter le débat politique de notre temps quelle moralité nouvelle, autre que la souveraineté, inventer pour des peuples européens qui, faute de pouvoir encore se faire la guerre, se sont du coup, sans autre projet, abandonnés au marché?
