We group the existing variants of the familiar set-theoretical and truth-theoretical paradoxes into two classes: connective paradoxes, which can in principle be ascribed to the presence of a contracting connective of some sort, and structural paradoxes, where at most the faulty use of a structural inference rule can possibly be blamed. We impute the former to an equivocation over the meaning of logical constants, and the latter to an equivocation over the notion of consequence. Both equivocation sources are tightly related, (...) and can be cleared up by adopting a particular substructural logic in place of classical logic. We then argue that our perspective can be justified via an informational semantics of contraction-free substructural logics. (shrink)

This paper provides an interpretation of the Routley-Meyer semantics for a weak negation-free relevant logic using Israel and Perry's theory of information. In particular, Routley and Meyer's ternary accessibility relation is given an interpretation in information-theoretic terms.

Abstract:A complex organization is in effect a commons, which supervisory techniques cannot preserve from free riding. A corporate culture strong enough to create the requisite community-minded second-order desires and beliefs may be morally illegitimate. What morality requires is not local enforcement of foundational moral principles—a futile undertaking—but that the organization be a good community in that it permits the disaffected to exit, encourages reflective consideration of morality and the good life, and creates appropriate loyalty.

In this paper, I argue that Ubuntu can be construed as a strict form of cosmopolitan moral and political theory. The implication of this is that the duty or obligation that humans owe other humans arises in virtue of humanity or the notion of human-ness. That is, one is a person insofar as he or she forms humane relations and it is this particular way of beingness that makes every person both an object and subject of duty. On this cosmopolitan (...) interpretation of Ubuntu, I therefore, argue that Ubuntu would support the principle of natural resource redistribution according to which all humans fall within the scope of justice and the principles of distributive justice. If this is right, then Ubuntu’s cosmopolitanism has something to contribute generally to cosmopolitanism, as an account of global justice. (shrink)

In this paper we set out a semantics for relevant (counterfactual) conditionals. We combine the Routley-Meyer semantics for relevant logic with a semantics for conditionals based on selection functions. The resulting models characterize a family of conditional logics free from fallacies of relevance, in particular counternecessities and conditionals with necessary consequents receive a non-trivial treatment.

Abstract:Phillips and Margolis argue that moral philosophy is a poor basis for business ethics, but their narrow view of moral philosophy would exclude Aristotle, for one. They criticize me for assimilating states and organizations in using the Rawlsian device, but they put too much faith in Rawls’s distinction between states and voluntary organizations and pay too little attention to the continuities between them. Their plea for a conceptually autonomous ethics for organizations I interpret as reasonable and largely compatible with my (...) own stated opinion. (shrink)

Models are constructed for a variety of systems of quantified relevance logic with identity. Models are given for systems with different principles governing the transitivity of identity and substitution, and the relative merits of these principles are discussed. The models in this paper are all extensions of the semantics of Fine's Semantics for Quantified Relevance Logic (Journal of Philosophical Logic 17 (1988)).

In "Doing Well Enough: Toward a Logic for Common Sense Morality", Paul McNamara sets out a semantics for a deontic logic which contains the operator It is supererogatory that. As well as having a binary accessibility relation on worlds, that semantics contains a relative ordering relation, . For worlds u, v and w, we say that u w v when v is at least as good as u according to the standards of w. In this paper we axiomatize logics complete (...) over three versions of the semantics. We call the strongest of these logics DWE for Doing Well Enough. (shrink)

Abstract:We have reached a rough moral consensus in the field of business ethics. We believe in capitalism with a safety net and enough regulation to deal with serious market imperfections. We favor autonomy for individuals and democracy for governments, though not necessarily for organizations. We recognize the rights of citizens and the different rights of employees. We respect a variety of possible sets of values, and so countenance a distinction between public and private. In other words, we are capitalists, pluralists, (...) and liberals. But globalization will force us and businesspeople who share our views to deal with significant stakeholders who do not. The 21st century will see the accelerating pace of globalization. The great challenge for business ethics, for its philosophers and its scholars of business, will be to identify and advocate morality that takes adequate account of globalization, and that in so doing avoids untenable parochialism without falling into relativism.

This paper uses an atomistic ontology of universals, individuals, and facts to provide a semantics for ramified type theory. It is shown that with some natural constraints on the sort of universals and facts admitted into a model, the axiom of reducibility is made valid.

ABSTRACT Objectives: To investigate whether Chinese adolescents in Hong Kong share similar perceptions with their Western counterparts regarding their capacity for autonomous decision‐making, and secondarily whether Chinese parents underestimate their adolescent children's desire and capacity for autonomous decision‐making. Method:‘Healthy Adolescents’ and their parents were recruited from four local secondary schools, and ‘Sick Adolescents’ and their parents from the pediatric wards and outpatient clinics. Their perceptions of adolescents' understanding of illnesses and treatments, maturity in judgment, risk‐taking, openness to divergent opinions, pressure (...) from parents and doctors, submission to parental authority and preference for autonomy in medical decision‐making are surveyed by a 50‐item questionnaire on a five‐point Likert scale. Results: Findings indicate that Chinese adolescents aged 14–16 perceive themselves to possess the necessary cognitive abilities and maturity in judgment to be autonomous decision‐makers like their Western counterparts. Paradoxically, although they hesitate to assert their autonomy, they are also unwilling to surrender that autonomy to their parents even under coercion or intimidation. Parents tend to underestimate their adolescents' preferences for making autonomous decisions and overestimate the importance of parental authority in decision‐making. Conclusion:‘14‐and‐above’ Chinese adolescents in Hong Kong perceive themselves as capable of autonomous decision‐making in medically‐related matters, but hesitate to assert their autonomy, probably because of the Confucian values of parental authority and filial piety that are deeply embedded in the local culture.

Connecting people across the digital divide is as much a social effort as a technological one. We are developing a community-centred approach to learn how interaction techniques can compensate for poor communication across the digital divide. We have incorporated the lessons learned regarding social intelligence design in an abstraction and in a device called the SoftBridge. The SoftBridge allows communication to flow from endpoints through adapters, getting converted if necessary, and out to destination endpoints. Field trials are underway with two (...) communities in South Africa: disadvantaged Deaf users and an isolated rural community. Initial lessons learned show that we have to design user interfaces that allow users to understand and cope with delay. We also learned that social concerns are often more important than the technical issues in designing such systems. (shrink)

The present essay, reposing on phenomena of derivation and semantics, will attempt to establish a more objective basis for the syntax of the impersonals. As a matter of syntax, the subject is of vital interest for the living Germanic tongues, and with these the essay begins. It will continue with a discussion of the phenomena of the Latin impersonals, and seek, by the help of living English usage, to establish upon a correct psychological basis the definition and derivation of the (...) least elusive impersonals of emotion in Sanskrit and Latin.

My thesis is simple. The right of informational privacy, the great modern achievement often attributed to the classic Samuel Warren and Louis Brandeis article, “The Right to Privacy” , asserts an individual's right not to have private personal information circulated. Warren and Brandeis claimed that individual dignity in a modern society requires that people be able to keep their private lives to themselves and proposed that the common law should be understood to protect this dignity by making dissemination of private (...) information a tort. As broadly stated, this right not to have private information distributed directly conflicts with a broadly conceived freedom of speech and of the press. My claim is that, in cases of conflict, the law should reject the Warren and Brandeis innovation. Speech and press freedom should prevail; the privacy tort should be ignored. This conclusion requires a normative argument concerning the appropriate basis and status of speech freedom that this essay will not really provide but for which I have argued elsewhere. Here, instead, I will describe that theory of speech freedom, explore its implications for informational privacy, and finally suggest some reasons to think that rejection of the privacy tort should not be so troubling and is, in fact, pragmatically desirable.

In this study, we explain differences in support for interreligious lawful and violent protests against the religious outgroup. Combining religiosity and social identity approaches, we take three dimensions of religiosity (namely, practices, beliefs and salience) into consideration related to support for interreligious conflict, next to relevant control characteristics. The analysis is based on survey data ( N = 2026) collected among a random sample of Muslims ( n = 1451) and Christians ( n = 575) across the Indonesian archipelago. Our (...) findings show that members of the Muslim community are, on average, more inclined to support interreligious conflict, both lawful and violent protests. Participation in rites of passage is a crucial aspect of religious practices found to be positively related to both kinds of protest. Religious beliefs show great importance but vary in their influence: particularistic views and intratextual fundamentalism are related to support for lawful protest, whereas religiocentrism is related to support both for lawful and violent protests. In contrast, salience reduces support for violent protest. As such, the findings offer a differentiated way to understand present-day interreligious conflicts among the general population in Indonesia. (shrink)

This paper sets out a semantics for C.I. Lewis's logic S2 based on the ontology of his 1923 paper ‘Facts, Systems, and the Unity of the World’. In that article, worlds are taken to be maximal consistent systems. A system, moreover, is a collection of facts that is closed under logical entailment and conjunction. In this paper, instead of defining systems in terms of logical entailment, I use certain ideas in Lewis's epistemology and philosophy of logic to define a class (...) of models in which systems are taken to be primitive elements but bear certain relations to one another. I prove soundness and completeness for S2 over this class of models and argue that this semantics makes sense of at least a substantial fragment of Lewis's logical theory. (shrink)

Much theorizing about altruism has been undertaken within a naturalistic and deterministic sociobiological framework that has sought to explain altruistic action in terms of underlying genetic selfishness. Recently, however, social constructionist thinkers have developed an alternative to such theorizing which suggests that human action arises out of fundamentally open-ended and malleable social relationships. This paper intends to show, however, that a reductive egoism is nonetheless still at work in such accounts, typically taking the form of an underlying concern for matters (...) of personal status and social recognition. As a response, this paper will briefly outline the work of the French phenomenologists Maurice Merleau-Ponty and Emmanuel Levinas as an example of non-reductive and fundamentally Other-oriented alternatives to both sociobiological and social constructionist accounts of altruistic action.
