An algebraic semantics, based on factor algebras, for one-way and two-way implicative verbs is proposed. Implicative verbs denote elements of filters or of ideals generated by identity functions in factor algebras. This semantics explains in particular the problem of implicational equivalence raised by two-way implicative verbs, and shows that the negation necessary to establish the implicativity of these verbs is the negation which preserves the presuppositions of sentences with implicative verbs. In addition, it follows from the proposed semantics that any (...) two implicative verbs denoting in the same algebra but belonging to different categories, are semantically related. (shrink)

The article studies two related issues. First, it introduces the notion of the contraposition of quantifiers which is a “dual” notion of symmetry and has similar relations to co-intersectivity as symmetry has to intersectivity. Second, it shows how symmetry and contraposition can be generalised to higher order type quantifiers, while preserving their relations with other notions from generalized quantifiers theory.

A simple model accounting for semantic properties of propositional attitude operators in negative contexts with no reference to possible worlds is proposed. Verbs occurring in such operators denote relations between individuals and specific sets of sentences (of a given natural language) and their negation is defined as the complement within a specific set of cognitively determined sentences. This approach avoids in particular the problem of intensionality of propositional attitude operators and allows to use many tools from the generalised quantifier theory. (...) In that way the negation giving rise to factive presuppositions and to the neg-raising is defined in a natural way. (shrink)

The notion of anaphoric conservativity, that is a property of specific functions taking sets and binary relations as arguments is studied. Such functions are denotations of anaphoric determiners forming nominal anaphors. It is shown that anaphoric conservativity is strictly stronger that ordinary conservativity of this type of functions. In consequence some novel semantic descriptions of reflexive and reciprocal pronouns are provided and a semantic universal stating that reflexive and reciprocal non-possessive determiners denote anaphorically conservative functions is proposed.

We provide necessary and sufficient conditions determining how monotonicity of some classes of reducible quantifiers depends on the monotonicity of simpler quantifiers of iterations to which they are equivalent.

A type quantifier F is symmetric iff F ( X, X )( Y ) = F ( Y, Y )( X ). It is shown that quantifiers denoted by irreducible binary determiners in natural languages are both conservative and symmetric and not only conservative.

It is shown that the notion of the partition of a set can be used to describe in a uniform way the meaning of the expression the same, in its basic uses in transitive and ditransitive sentences. Some formal properties of the function denoted by the same, which follow from such a description are indicated. These properties indicate similarities and differences between functions denoted by the same and generalised quantifiers.

Quanti cateurs Q1 et Q2 du type <1> sont faiblement indépendants si et seulement si Q1Q2(R) = Q2Q1(R1) pour toute relation- produit R. On donne une condition suf sante et nécessaire pour que deux quanti cateurs soient faiblement indépendants.

If non-human animals experience wellbeing and suffering, such welfare consequences arguably should be included in a social welfare evaluation. Yet economic evaluations almost universally ignore non-human animals, in part because axiomatic social choice theory has failed to propose and characterize multi-species social welfare functions. Here we propose axioms and functional forms to fill this gap. We provide a range of alternative representations, characterizing a broad range of possibilities for multi-species social welfare. Among these, we identify a new characterization of additively-separable (...) generalized (multi-species) total utilitarianism. The multispecies setting permits a novel, weak species-level separability axiom with important consequences. We provide examples to illustrate that non-separability across species is implausible in a multi-species setting, in part because good lives for different species are at very different welfare levels. Finally, we explore the consequences for evaluating climate policy and understanding speciesism and non-climate environmental goals, such as biodiversity. (shrink)

Dans cet article sont examinés les différents sens du mot «probable» tel qu'il apparaît dans certains commentaires desTopiques d'Aristote, notamment ceux d'Alexandre d'Aphrodise, d'Averroès et surtout celui d'Agostino Nifo, ainsi que dans des traités qui s'en inspirent, notamment leDe dialogo de Carlo Sigonio et leDe inventione dialectica de Rudolph Agricola. On retrouve dans ces écrits les trois sens principaux de ce mot depuis Aristote et Cicéron: celui d'opinion communément admise, celui d'opinion qui correspond à «ce qui se passe la plupart (...) du temps» et celui d'opinion apte à produire la persuasion. À partir de cette polysémie du mot «probable», l'article met en évidence les différentes fonctions attribuées aux opinions probables dans ces divers écrits, plus particulièrement au XVIe siècle. L'association du mot «probable» avec la notion de vérité contingente conduit à mettre en valeur le lien entre hypothèse probable et conjecture. (shrink)

Software systems play an ever more important role in our lives and software engineers and their companies find themselves in a position where they are held responsible for ethical issues that may arise. In this paper, we try to disentangle ethical considerations that can be performed at the level of the software engineer from those that belong in the wider domain of business ethics. The handling of ethical problems that fall into the responsibility of the engineer has traditionally been addressed (...) by the publication of Codes of Ethics and Conduct. We argue that these Codes are barely able to provide normative orientation in software development. The main contribution of this paper is, thus, to analyze the normative features of Codes of Ethics in software engineering and to explicate how their value-based approach might prevent their usefulness from a normative perspective. Codes of Conduct cannot replace ethical deliberation because they do not and cannot offer guidance because of their underdetermined nature. This lack of orientation, we argue, triggers reactive behavior such as “cherry-picking,” “risk of indifference,” “ex-post orientation,” and the “desire to rely on gut feeling.” In the light of this, we propose to implement ethical deliberation within software development teams as a way out.

The Repugnant Conclusion served an important purpose in catalyzing and inspiring the pioneering stage of population ethics research. We believe, however, that the Repugnant Conclusion now receives too much focus. Avoiding the Repugnant Conclusion should no longer be the central goal driving population ethics research, despite its importance to the fundamental accomplishments of the existing literature.

Julian Nida-Rümelin’s philosophical approach to rationality is radical: It transcends the reductive narrowness of instrumental rationality without denying its practical impact. Actions exist which are carried out in accordance to utility maximizing or even self-interest maximizing. Yet not all actions are to be understood in these terms. Actions that are oriented around social roles, for example, cannot count as irrational just because no underlying maximizing heuristics are found. The concept of bounded rationality tries to embed instrumental rationality into a form (...) of life to highlight limits of our cognitive capabilities and selective perceptions. However, the agent is still situated within the realm of cost-benefit reasoning. The idea of social preferences (e.g. Rabin, Fehr and Schmidt) or meta-preferences (Sen) is insufficient to reflect the plurality of human actions. According to Nida-Rümelin, those concepts ignore the plurality of reasons which drive agency. Hence, they try to fit agency into a theory which undermines humanity. His theory of structural rationality acknowledges daily patterns of interaction and meaning. (shrink)

"Williams's masterful translation satisfies (at last!) a long-standing need. There are lots of good translations of Augustine's great work, but until now we have been forced to choose between those that strive to replicate in English something of the majesty and beauty of Augustine's Latin style and those that opt instead to convey the careful precision of his philosophical terminology and argumentation. Finally, Williams has succeeded in capturing both sides of Augustine's mind in a richly evocative, impeccably reliable, elegantly readable (...) presentation of one of the most impressive achievements in Western thought--Augustine's Confessions." --Scott MacDonald, Professor of Philosophy and Norma K.

While issues of efficacy and specificity are crucial for the future of neurofeedback training, there may be alternative designs and control analyses to circumvent the methodological and ethical problems associated with double-blind placebo studies. Surprisingly, most NF studies do not report the most immediate result of their NF training, i.e. whether or not children with ADHD gain control over their brain activity during the training sessions. For the investigation of specificity, however, it seems essential to analyze the learning and adaptation (...) processes that take place in the course of the training and to relate improvements in self-regulated brain activity across training sessions to behavioral, neuropsychological and electrophysiological outcomes. To this aim, a review of studies on neurofeedback training with ADHD patients, which include the analysis of learning across training sessions or relate training performance to outcome, is presented. Methods on how to evaluate and quantify learning of EEG regulation over time are discussed. “Non-learning” has been reported in a small number of ADHD-studies, but has not been a focus of general methodological discussion so far. For this reason, selected results from the brain-computer interface (BCI) research on the so-called “brain-computer illiteracy”, the inability to gain control over one’s brain activity, are also included. It is concluded that in the discussion on specificity, more attention should be devoted to the analysis of EEG regulation performance in the course of the training and its impact on clinical outcome. It is necessary to improve the knowledge on characteristic cross-session and within-session learning trajectories in ADHD and to provide the best conditions for learning. (shrink)

Research by academics, professional organizations, and businesses on ethics in the workplace often relies on surveys that ask employees to report how frequently they have observed others engaging in unethical behavior. But what do these frequencies in observer-reports say about the frequencies of committed unethical behavior? This paper is the first to address this question by empirically exploring the relationship between observer- and self-reports. Our survey research among the Swiss working population shows that for all 37 different forms of unethical (...) behavior investigated, observer-reports show higher frequencies than self-reports. Ratios of observer- to self-reports vary substantially among these forms, ranging from 1.46 for improperly gathering competitor’s confidential information to 6.4 for engaging in (sexual) harassment or creating a hostile work environment. The results indicate that researchers should not assume that the frequency in self-reports can generally be approximated by the frequency in observer-reports. Four possible explanations are presented for the differences in ratios, with recommendations for future research. (shrink)

The spread of unethical behavior in organizations has mainly been studied in terms of processes occurring in a general social context, rather than in terms of actors’ reactions in the context of their specific social relationships. This paper introduces a dynamic social network analysis framework in which this spread is conceptualized as the result of the reactions of perpetrators, victims, and observers to an initial act of unethical behavior. This theoretical framework shows that the social relationships of the actors involved (...) in an initial act impact in multiple ways the likelihood that unethical behavior spreads. It reveals furthermore that social relationships may change in the wake of unethical behavior, such that indirect negative consequences can arise for organizations. The proposed framework provides a basis for the development of a formal stochastic actor-oriented model of network dynamics which would enable simulations of the spread of unethical behavior.

In this exploratory paper, we investigate the extension of Haidt’s :814–834, 2001, The righteous mind: Why good people are divided by politics and religion, 2012) Moral foundations theory, operationalized as the MFQ30 questionnaire, from a sample of the general public across many countries to a sample of business students. MFT posits that people rely on five major concerns, or foundations, when making moral judgments. The five concerns are care/harm, fairness/cheating, loyalty/betrayal, respect/authority, and purity/degradation. In addition, Haidt suggests that intuition, rather (...) than reasoning, leads to moral judgment. We replicate Haidt’s measurement model and find that the measurement model based on our sample is consistent. This indicates support for MFT. Further, we find structural differences in the measurement model between the genders and between areas of study. Our findings suggest that all students in the sample focus substantially on the fairness foundation. Ethics education and research may seek to expand the number of moral foundations individuals consider when discerning whether something is right or wrong. (shrink)

Les femmes mises en images abondent dans les livres d'histoire, de sociologie ou d'esthétique.

The Moral Nexus develops and defends a new interpretation of morality—namely, as a set of requirements that connect agents normatively to other persons in a nexus of moral relations. According to this relational interpretation, moral demands are directed to other individuals, who have claims that the agent comply with these demands. Interpersonal morality, so conceived, is the domain of what we owe to each other, insofar as we are each persons with equal moral standing. The book offers an interpretative argument (...) for the relational approach. Specifically, it highlights neglected advantages of this way of understanding the moral domain; explores important theoretical and practical presuppositions of relational moral duties; and considers the normative implications of understanding morality in relational terms. The book features a novel defense of the relational approach to morality, which emphasizes the special significance that moral requirements have, both for agents who are deliberating about what to do and for those who stand to be affected by their actions. The book argues that relational moral requirements can be understood to link us to all individuals whose interests render them vulnerable to our agency, regardless of whether they stand in any prior relationship to us. It also offers fresh accounts of some of the moral phenomena that have seemed to resist treatment in relational terms, showing that the relational interpretation is a viable framework for understanding our specific moral obligations to other people.

L’histoire de la jeune Salomé charmant par sa danse le roi Hérode et obtenant de lui la tête de Jean Baptiste a été souvent représentée dans l’art italien de la Renaissance. La confrontation de quelques images des xive et xve siècles avec un texte de Francesco da Barberino au xive siècle veut éclairer l’évolution du regard jeté sur la danseuse et sur la danse en cette extrême fin du Moyen Âge, qui nuance les violentes condamnations cléricales des périodes précédentes.
