Television medical dramas frequently depict the practice of medicine and bioethical issues in a strikingly realistic but sometimes inaccurate fashion. Because these shows depict medicine so vividly and are so relevant to the career interests of medical and nursing students, they may affect these students' beliefs, attitudes, and perceptions regarding the practice of medicine and bioethical issues. We conducted a web-based survey of medical and nursing students to determine the medical drama viewing habits and impressions of bioethical issues depicted in (...) them. More than 80% of medical and nursing students watch television medical dramas. Students with more clinical experience tended to have impressions that were more negative than those of students without clinical experience. Furthermore, viewing of television medical dramas is a social event and many students discuss the bioethical issues they observe with friends and family. Television medical dramas may stimulate students to think about and discuss bioethical issues. (shrink)

This paper sets out a philosophical interpretation of the model theory of Mares and Goldblatt (The Journal of Symbolic Logic 71, 2006). This interpretation distinguishes between truth conditions and information conditions. Whereas the usual Tarskian truth condition holds for universally quantified statements, their information condition is quite different. The information condition utilizes general propositions . The present paper gives a philosophical explanation of general propositions and argues that these are needed to give an adequate theory of general information.

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.

This paper presents a theory of belief revision that allows people to come tobelieve in contradictions. The AGM theory of belief revision takes revision,in part, to be consistency maintenance. The present theory replacesconsistency with a weaker property called coherence. In addition to herbelief set, we take a set of statements that she rejects. These two sets arecoherent if they do not overlap. On this theory, belief revision maintains coherence.

It may be nearly impossible to use standard principles to make a decision about a complex ethical case. The best decision, say virtue ethicists in the Aristotelian tradition, is often one that is made by a person of good character who knows the salient facts of the case and can frame the situation appropriately. In this respect ethical decisions and strategic decisions are similar. Rationality plays a role in good ethical decision-making, but virtue ethicists emphasize the importance of intuitions and (...) emotions as well.Virtue ethics suggests a reconciliation of the factual and the normative. Virtues may explain as well as justify actions. The same is true of other psychological states and events. That psychological terms have normative implications does not render them useless in explanation. As Aristotle does not distinguish cleanly between the normative and empirical, so many moral philosophers today reject the is-ought dichotomy. They are prepared to learn from economists, psychologists, and other empirical scientists who offer information about the nature of the good life and of values. Social psychologists who study community or corporate culture suggest a close relationship between organizational and ethical features, much as Aristotle saw a close relationship between politics and ethics. We should infer from all this that in business ethics there is good reason for philosophers and organization scholars to work closely together. (shrink)

This paper extends the theory of situated inference from Mares to treat two weak relevant logics, B and DJ. These logics are interesting because they can be used as bases for consistent naïve theories, such as naïve set theory. The concepts of a situation and of information that are employed by the theory of situated inference are used to justify various aspects of these logics and to give an interpretation of the notion of set that is represented in the naïve (...) set theories that are based on them.

The purpose of this paper is to show that semantics for relevance logic, based on the Routley-Meyer semantics, can be given without using the Routley star operator to treat negation. In the resulting semantics, negation is treated implicationally. It is shown that, by the use of restrictions on the ternary accessibility relation, simplified by the use of some definitions, a semantics can be stipulated over which R is complete.

Many authors have posited an “object file” system, which underlies perceptual selection and tracking of objects. Several have proposed that this system internalizes principles specifying what counts as an object and relies on them during tracking. Here I consider a popular view on which the object file system is tuned to entities that satisfy principles of three-dimensionality, cohesion, and boundedness. I argue that the evidence gathered in support of this view is consistent with a more permissive view on which object (...) files select and track according to well-known perceptual organization criteria. Further evidence supplies positive support for the permissive view. (shrink)

The logic CE (for "Classical E") results from adding Boolean negation to Anderson and Belnap's logic E. This paper shows that CE is not a conservative extension of E.

This paper sets out two semantics for the relevant logic R based on Dunn's four-valued semantics for first-degree entailments. Unlike Routley's semantics for weak relevant logics, they do not use two ternary accessibility relations. Unlike Restall's semantics, they capture all of R. But there is a catch. Both of the present semantics are neighbourhood semantics, that is, they include sets of propositions in the specification of their frames.

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)

Behaviorism is consistent with the assumptions of perfect competition, with the homo economicus model, and with a form of ethics that enshrines market-based notions of utility, justice, and rights and encourages rational maximizing. Economics and business courses foster this deficient form of ethics, assuming an overriding desire for money, which, according to MacIntyre and Aristotle, crowds out the associative virtues. These beliefs, often associated with Taylor and Friedman, lead to such practices as incentive compensation, which would be effective only if (...) employees were homines economici and thus rational in the sense of knowing how to satisfy whatever desires they have. Against Davidson’s view that psychology cannot be a natural science, Aristotle believes that there can be a teleological, if not exact, science of behavior. Aristotle believes that emotions and objectives may be rational or irrational. But rationality—phronesis, practical wisdom—is not a matter of applying algorithms. Doris questions whether character generates the first premises of an agent’s practical syllogisms, while Haidt has argued that we often act on emotions rather than on the basis of the reasons that we claim motivate us. Aristotle agrees that many people are not virtuous and that weakness of the will is a common occurrence, and he agrees that emotion drives actions. But if you are virtuous, your emotions and desires support your rationality. Aristotle gives us reason to reject the notion that people are homines economici and to treat them as rational deliberators, in part by creating an appropriate culture. The claim that it is in the nature of human beings to deliberate rationally is in part aspirational, but also in part scientific—in Aristotle’s modest sense. (shrink)

In recent years many influential philosophers have advocated that philosophy is an a priori science. Yet very few epistemology textbooks discuss a priori knowledge at any length, focusing instead on empirical knowledge and empirical justification. As a priori knowledge has moved centre stage, the literature remains either too technical or too out of date to make up a reasonable component of an undergraduate course. Edwin Mares book aims to rectify this. This book seeks to make accessible to students the (...) standard topics and current debates within a priori knowledge, including necessity and certainty, rationalism, empiricism and analyticity, Quine's attack on the a priori, Kantianism, Aristotelianism, mathematical knowledge, moral knowledge, logical knowledge and philosophical knowledge.

In this paper, I set out a semantics for identity in relevant logic that is based on an analogy between the biconditional and identity. This analogy supports the semantics that Priest has set out for identity in basic relevant logic and it motivates a version of the Routley–Meyer semantics in which identities can be viewed as constraints on the ternary relation that is used to treat implication.

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 begins with a discussion of C. I. Lewis’s theory of meaning in his book, An Analysis of Knowledge and Valuation (1946) and his pragmatic theory of analyticity and necessity. I bring this theories together with some remarks that he makes in an appendix to the second edition of Symbolic Logic to construct an algebraic semantics for his logics S2 and S3. These logics and their semantics are compared and evaluated with regard to how well they implement Lewis’s theories (...) of meaning and analyticity. (shrink)

The fregean theory of meaning says how the meaningful parts of a meaningful expression contribute to that expression's sense and reference. But frege overlooks the fact that logical expressions play dual roles. The contributions of sentential connectives, For example, Are well described for contexts in which they connect sentences, But not for larger quantificational contexts. An obvious modification of the theory which might fill the abyss is considered, And it is maintained that it produces two difficulties: a replication of frege's (...) concept 'horse' troubles and an infinite proliferation of logical vocabulary. The seriousness of these difficulties is briefly discussed. (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)

The context and caption of a photograph often suggest that the content described is real. When this happens an assertion is made?at least implicitly. Newspapers provide such a context, and viewers naturally understand news photographs assertively. If in such a context, the content described is not real, then the viewer is likely to be deceived. Willful viewer deception is practiced by photographers in a variety of common situations in which it is unjustifiable.

We typically test norms with reference to their usefulness in dealing with social problems and issues, though sometimes we use hypernorms to evaluate them. The hypernorms that we find most acceptable do not guide action in the way local norms do. They do, however, raise challenging questions that we should ask in evaluating any practice and its associated norms. In this respect, they differ from the principles associated with traditional, as opposed to modern, morality. As societies become more alike, in (...) part as a result of globalization, they will face increasingly similar problems. Then their local norms will be more similar, and they will be more likely to share hypernorms. Insofar as we can agree to try to justify our hypernorms, we are likely to converge on the hypernorms characteristic of modern rather than traditional morality. But people are often attached to their old norms and so are not very good at seeing how hypernorms raise questions that challenge the old norms. Here moral imagination should aid in the adjustment process. A system of democratic capitalism is hospitable to a good kind of moral convergence. (shrink)

En este texto se exponen algunas ideas que surgen de una primera aproximación al pensamiento del lingüista neerlandés Teun Van Dijk, uno de los fundadores del análisis crítico del discurso. La intención en este trabajo es mostrar algunos elementos que nos permitan comprender cómo es que el poder se reproduce por medio del discurso. Para llegar a este objetivo primero tendremos que entender qué son las representaciones sociales y advertir la manera en que éstas se relacionan con el discurso. Se (...) advertirá que ocurre una doble relación, pues, veremos que, por un lado, las representaciones sociales constituyen el aspecto cognitivo que permite la expresión e interpretación de los discursos; y, por otro, las representaciones sociales se reproducen por medio del discurso. Finalmente, se mostrará que el poder se reproduce por medio del discurso implantando, con una determinada estrategia, representaciones sociales en la mente de las personas. Entré más se divulguen y perpetúen ciertas representaciones sociales, más efectivo será el discurso. (shrink)

Professor Fort (1999) imagines a dispute over the moral importance of certain facts, with David Messick and himself on one side and Donna Wood and me on the other. He has identified an important issue—ethical naturalism—but that issue is not a point of disagreement between Messick and me.Fort has some interesting ideas about how Messick’s views might help in creating organizations that are moral communities. Beyond noting that those ideas constitute the most important part of his essay and merit consideration, (...) I shall not comment on them.Moral philosophers who are naturalists—I am one—hold that there is no bright line between ought-statements and is-statements and that empirical facts have implications for moral facts. So, for example, that a certain practice helps a community survive is a strong sort of reason for claiming that it is a morally good practice, other things being equal. But most naturalists do not claim that any practice that has arisen by virtue of evolution isipso factoa morally good practice even if it does serve some purpose. Nor does ethical naturalism have a characteristic view of the extent to which our evolutionary history, as opposed to our rational deliberation, determines what we do. (shrink)
