W. David Solomon sits at the very center of the revival of virtue ethics. Solomon's work extended what began with the publication of G. E. M. Anscombe's "Modern Moral Philosophy" (1958) by solidifying virtue ethics as a viable approach within contemporary moral philosophy. Beyond the Self: Virtue Ethics and the Problem of Culture comprises twelve chapters: eleven that employ Solomon's work and legacy, followed by a twelfth concluding chapter by Solomon himself. Each chapter deepens and (...) develops virtue ethics as a rich intellectual tradition rooted in Aristotle and Thomas Aquinas. Editor Raymond Hain divides the volume into three sections. The first addresses the historical contexts of happiness, justice, and mercy in the tradition of Aristotle and Thomas Aquinas. The second turns to recent themes in normative ethics, focusing on topics such as morality, virtue, and egoism. The third discusses broader ethical issues with significant cultural implications, such as human dignity, physician-assisted suicide, and secularization. Beyond the Self uncovers the shortcomings of contemporary moral philosophy and the depth and capacity of the Aristotelian and Thomistic traditions, reminding the reader that classical virtue ethics remains the most promising framework for understanding the moral life. Contributors include: Michael Beaty, Kevin L. Flannery, Raymond Hain, John Haldane, Thomas Hibbs, Irfan Khawaja, Alasdair MacIntyre, John O'Callaghan, Bryan C. Pilkington, W. David Solomon, Christopher Toner, and Candace Vogler. (shrink)

Peter Abelard (1079–1142 ce) was the most wide‐ranging philosopher of the twelfth century. He quickly established himself as a leading teacher of logic in and near Paris shortly after 1100. After his affair with Heloise, and his subsequent castration, Abelard became a monk, but he returned to teaching in the Paris schools until 1140, when his work was condemned by a Church Council at Sens. His logical writings were based around discussion of the “Old Logic”: Porphyry's Isagoge, aristotle'S Categories and (...) On Interpretation and boethius'S textbook on topical inference. They comprise a freestanding Dialectica (“Logic”; probably c.1116), a set of commentaries (known as the Logica [Ingredientibus], c. 1119) and a later (c. 1125) commentary on the Isagoge (Logica Nostrorum Petititoni Sociorum or Glossulae). In a work Abelard called his Theologia, issued in three main versions (between 1120 and c.1134), he attempted a logical analysis of trinitarian relations and explored the philosophical problems surrounding God's claims to omnipotence and omniscience. The Collationes (“Debates,” also known as “Dialogue between a Christian, a Philosopher and a Jew”; probably c.1130) present a rational investigation into the nature of the highest good, in which the Christian and the Philosopher (who seems to be modeled on a philosopher of pagan antiquity) are remarkably in agreement. The unfinished Scito teipsum (“Know thyself,” also known as the “Ethics”; c.1138) analyses moral action. (shrink)

It is well known that Tarski proved a result which can be stated roughly as: no sufficiently rich, consistent, classical language can contain its own truth definition. Tarski's way around this problem is to deal with two languages at a time, an object language for which we are defining truth and a metalanguage in which the definition occurs. An obvious question then is: under what conditions can we construct a definition of truth for a given object language. Tarski claims that (...) it is necessary and sufficient that the metalanguage be "essentially richer". Our contention, put bluntly, is that this claim deserves more scrutiny from philosophers than it usually gets and in fact is false unless "essentially richer" means nothing else than "sufficient to contain a truth definition for the object language.".

Michael Friedman has recently argued that Carnap'sLogical Syntax of Language is fundamentally flawed in a way that reveals the ultimate failure of logical positivism. Friedman's argument depends crucially on two claims: (1) that Carnap was committed to the view that there is a universal metalanguage and (2) that given what Carnap wanted from a metalanguage, in particular given that he wanted a definition of analytic for an object language, he was in fact committed to a hierarchy of stronger and stronger (...) metalanguages. We argue that neither of these claims need be accepted. We show that there is no textual evidence for (1) and that if metalanguages are to be used for merely descriptive and not also justificatory purposes, Carnap does not need to define analyticity sufficiently for proving consistency, and so could have given a definition that does not entail a hierarchy of metalanguages.

RésuméCet article discute diverses confusions, actueles ou potentielles, liées á la bivalence et au tiers exclu. Il s'agit, en particulier, 1) d'examiner divers cas illustrant les rapports entre la bivalence et le tiers exclu ; 2) de discuter la thése selon laquelle le tiers exclu et le schéma-T de Tarskipour la vérité entraînent la bivalence; 3) de proposer quelques remarques sur les rapports entre la bivalence, le tiers exclu et la preuve par l'absurde; 4) de scruter un argument répandu selon (...) lequel le tiers exclu vaut pour les termes «précis» et 5) de commenter l'histoire de la terminologie. L'objectif ici est d'attirer l'attention des philosophes sur une distinction importante qui ne reçoit pas souvent le traitement minutieux qu'elle mérite. (shrink)

Logical Options introduces the extensions and alternatives to classical logic which are most discussed in the philosophical literature: many-sorted logic, second-order logic, modal logics, intuitionistic logic, three-valued logic, fuzzy logic, and free logic. Each logic is introduced with a brief description of some aspect of its philosophical significance, and wherever possible semantic and proof methods are employed to facilitate comparison of the various systems. The book is designed to be useful for philosophy students and professional philosophers who have learned some (...) classical first-order logic and would like to learn about other logics important to their philosophical work.

Skinner has assigned the persistence of cognitive explanations to the literature of freedom and dignity. This view is challenged especially as it applies to behavioral scientists. It is argued that cognitive explanations persist because current behaviorism does not challenge cognitive epistomology; because behavior analysts have failed to provide research evidence at the level of human behavior, and finally because a science of behavior based solely on operant principles is necessarily incomplete. The implications of these problems for behavior analysis are addressed.

We discuss in this paper the question of the scope of the principle of tolerance about languages promoted in Carnap's The Logical Syntax of Language and the nature of the analogy between it and the rudimentary conventionalism purportedly exhibited in the work of Poincaré and Hilbert. We take it more or less for granted that Poincaré and Hilbert do argue for conventionalism. We begin by sketching Coffa's historical account, which suggests that tolerance be interpreted as a conventionalism that allows us (...) complete freedom to select whatever language we wish—an interpretation that generalizes the conventionalism promoted by Poincaré and Hilbert which allows us complete freedom to select whatever axiom system we wish for geometry. We argue that such an interpretation saddles Carnap with a theory of meaning that has unhappy consequences, a theory we believe he did not hold. We suggest that the principle of linguistic tolerance in fact has a more limited scope; but within that scope the analogy between tolerance and geometric conventionalism is quite tight. (shrink)

In the context of a discussion of time symmetry in the quantum mechanical measurement process, Aharonov et al. (1964) derived an expression concerning probabilities for the outcomes of measurements conducted on systems which have been pre- and postselected on the basis of both preceding and succeeding measurements. Recent literature has claimed that a resulting "time-symmetrized" interpretation of quantum mechanics has significant implications for some basic issues, such as contextuality and determinateness, in elementary, nonrelativistic quantum mechanics. Bub and Brown (1986) have (...) shown that under the standard interpretation of the aforementioned expression, these claims employ ensembles which are not well defined. It is argued here that under a counterfactual interpretation of the expression, these claims may be understood as employing well-defined ensembles; it is shown, however, that such an interpretation cannot be reconciled with the standard interpretation of quantum mechanics.

We analyze three applications of Ramsey’s Theorem for 4-tuples to infinite traceable graphs and finitely generated infinite lattices using the tools of reverse mathematics. The applications in graph theory are shown to be equivalent to Ramsey’s Theorem while the application in lattice theory is shown to be provable in the weaker system RCA0.

Airline pilots are attributed ultimate responsibility and final authority over their aircraft to ensure the safety and well-being of all its occupants. Yet, with the advent of automation technologies, a dissonance has emerged in that pilots have lost their actual decision-making authority as well as their ability to act in an adequate fashion towards meeting their responsibilities when unexpected circumstances or emergencies occur. Across the literature in human factor studies, we show how automated algorithmic technologies have wrestled control away from (...) airline pilots. The inter-related ethical and pragmatic consequences resulting from such a dissonance are presented. This includes pilots serving as ‘legal sponges’, being caught in ‘moral crumple zones’, as well as real impacts on safety and well-being of passengers and crew. One potential avenue presented in the literature involves a redistribution of responsibility towards all agential entities within the cockpit system. We discuss the possible pitfalls to this approach, including the reinforcement of pilot skills erosion as well as technology’s own limitations in adaptively dealing with unexpected circumstances. We justify our position by showing how algorithmic technology’s representational frames mask or severely limit the pilots’ natural reflex to ‘practically cope’ and gain an ‘optimal grip’ with a given context/situation at hand. Here, we present the concept of relevant or meaningful control, which pilots, when allowed to develop their natural brain-body reflexes, gain across gradual mastery of the aircraft. Finally, we propose a socio-technical design approach in which pilots can re-appropriate full human meaningful control of the aircraft, thus allowing them to meet their attributed responsibilities.

Activity anorexia illustrates selection of behavior at the biological, behavioral, and neural levels. Based on evolutionary history, food depletion increases the reinforcement value of physical activity that, in turn, decreases the reinforcement effectiveness of eating – resulting in activity anorexia. Neural opiates participate in the selection of physical activity during periods of food depletion.

Recent developments in quantum physics postulate the existence of some form of multiverse, often considered inimical to theism. We argue that a cosmology of many worlds is not novel either to philosophy or to theism. The multiverse is not a monolithic concept and we refer to and use the four levels of categorization proposed by Max Tegmark. We trace the idea of a multiverse back to the Milesians and Epicureans in order to initially demonstrate its use of a plenitude argument. (...) We then examine the argument for possible compatibility based on a theistic principle of plenitude in three specifically Christian theists: Origen, Thomas Aquinas, and G. W. Leibniz. We conclude that this argument is sustainable so that if any level of the multiverse actually exists then it is harmonious with theism, and we argue that its fit is most successful if a multiverse is considered as a single possible world. We call this view Thomistic modal realism. (shrink)

The following hypothetical case study was developed for bioengineering students and is concerned with choosing between two devices used for development of a pediatric tissue engineered heart valve (TEHV). This case is intended to elicit assessment of the devices, possible future outcomes, and ramifications of the decision making. It is framed in light of two predominant ethical theories: utilitarianism and rights of persons. After the case was presented to bioengineering graduate students, they voted on which device should be released. The (...) results revealed that these bioengineering students preferred the more reliable (and substantially more expensive) design, though this choice precludes the majority of the world from having access to this technology. This case is intended to examine and explore where the balance lies between design, cost, and adequate distribution of biomedical devices. (shrink)
