Dynamic topological logic provides a context for studying the confluence of the topological semantics for S4, topological dynamics, and temporal logic. The topological semantics for S4 is based on topological spaces rather than Kripke frames. In this semantics, □ is interpreted as topological interior. Thus S4 can be understood as the logic of topological spaces, and □ can be understood as a topological modality. Topological dynamics studies the asymptotic properties of continuous maps on topological spaces. Let a dynamic topological system (...) be a topological space X together with a continuous function f. f can be thought of in temporal terms, moving the points of the topological space from one moment to the next. Dynamic topological logics are the logics of dynamic topological systems, just as S4 is the logic of topological spaces. Dynamic topological logics are defined for a trimodal language with an S4-ish topological modality □, and two temporal modalities, ○ and *, both interpreted using the continuous function f. In particular, ○ expresses f’s action on X from one moment to the next, and * expresses the asymptotic behaviour of f. (shrink)

Technological advances in veterinary medicine have produced considerable progress in the diagnosis and treatment of numerous diseases in animals. At the same time, veterinarians, veterinary technicians, and owners of animals face increasingly complex situations that raise questions about goals of care and correct or reasonable courses of action. These dilemmas are frequently controversial and can generate conflicts between clients and health care providers. In many ways they resemble the ethical challenges confronted by human medicine and that spawned the creation of (...) clinical ethics committees as a mechanism to analyze, discuss, and resolve disagreements. The staff of the North Carolina State University Veterinary Hospital, a specialty academic teaching institution, wanted to investigate whether similar success could be achieved in the tertiary care veterinary setting. We discuss the background and rationale for this method, as well as the approach that was taken to create a clinical ethics committee. (shrink)

David Lewis [1988; 1996] canvases an anti-Humean thesis about mental states: that the rational agent desires something to the extent that he or she believes it to be good. Lewis offers and refutes a decision-theoretic formulation of it, the 'Desire-as-Belief Thesis'. Other authors have since added further negative results in the spirit of Lewis's. We explore ways of being anti-Humean that evade all these negative results. We begin by providing background on evidential decision theory and on Lewis's negative results. We (...) then introduce what we call the indexicality loophole: if the goodness of a proposition is indexical, partly a function of an agent's mental state, then the negative results have no purchase. Thus we propose a variant of Desire-as-Belief that exploits this loophole. We argue that a number of meta-ethical positions are committed to just such indexicality. Indeed, we show that with one central sort of evaluative belief--the belief that an option is right--the indexicality loophole can be exploited in various interesting ways. Moreover, on some accounts, 'good' is indexical in the same way. Thus, it seems that the anti-Humean can dodge the negative results. (shrink)

This is an exploration of some problems of nonexistence, with special attention paid to Nathan Salmón’s account of merely possible and impossible objects (or entities or things). According to this account, we can refer to such objects and attribute properties to them. The terms ‘possible’ and ‘impossible’ should be understood in the familiar metaphysical sense, so that a merely possible object is one that does not exist at the actual world but exists at some metaphysically possible world (it could exist (...) even though it does not) and an impossible object is one that does not exist at any metaphysically possible world (it could not exist at all). Other nonexistents, such as objects that once existed at the actual world but no longer do, will also be discussed, but mainly by way of comparison to merely possible and impossible objects. Salmón subscribes to both the direct reference theory of names and the Millian theory of names. Section I is a preliminary discussion of these theories, contrasting them with the formerly orthodox views of Frege and Russell. Section II presents Salmón’s account of merely possible and impossible objects. Sections III and IV are an evaluation and defense of a modified version of the account. Among other things, it is argued that Salmón’s account does not slip into any problematic form of Meinongianism. However, section V questions why Salmón’s account of impossible objects would not extend to Meinong’s notorious round square. (shrink)

Explores the social ramifications of Kant's concept of radical evil.

Contemporary discussions of skepticism often frame the skeptic's argument around an instance of the closure principle. Roughly, the closure principle states that if a subject knows p, and knows that p entails q, then the subject knows q. The main contention of this paper is that the closure argument for skepticism is defective. We explore several possible classifications of the defect. The closure argument might plausibly be classified as begging the question, as exhibiting transmission failure, or as structurally inefficient. Interestingly, (...) perhaps, each of these has been proposed as the correct classification of Moore's proof of an external world. (shrink)

Bruineberg et al. provide compelling clarity on the roles Markov blankets could (and perhaps should) play in the study of life and mind. However, here we draw attention to a further role blankets might play: as a hypothesis about cognition itself. People and other animals may use blanket-like representations to model the boundary between themselves and their worlds.

The orthodox view in contemporary epistemology is that Edmund Gettier refuted the JTB analysis of knowledge, according to which knowledge is justified true belief. In a recent paper Moti Mizrahi questions the orthodox view. According to Mizrahi, the cases that Gettier advanced against the JTB analysis are misleading. In this paper I defend the orthodox view.

Russellianism is the view that the meaning of a proper name is the individual designated by the name. Together with other plausible assumptions, Russellianism entails the following: Sentences containing proper names express Russellian propositions, which involve the individual designated by the name as a direct constituent, and which can be represented as sets of individuals and properties. Moreover, as they occur in ordinary belief reports, ‘that’-clauses designate Russellian propositions. Such belief reports are true if and only if the subject of (...) the belief report bears the belief relation to the proposition designated by the ‘that’-clause. In defending this doctrine, some Russellians appeal to propositional guises, which, roughly speaking, are ways of grasping propositions. However, some Russellians don’t appeal to such entities. In this paper, I explain the varieties of Russellianism and then argue for Modest Russellianism: Believing a Russellian proposition is essentially mediated by guises, so that an agent can’t believe a Russellian proposition without standing in some appropriate relation to both the proposition and a guise. Nonetheless, guises don’t feature in the semantics of ordinary belief reports, so that an adequate account of the meaning of such belief reports needn’t invoke guises. (shrink)

Characterizing how activity in the central and autonomic nervous systems corresponds to distinct emotional states is one of the central goals of affective neuroscience. Despite the ease with which individuals label their own experiences, identifying specific autonomic and neural markers of emotions remains a challenge. Here we explore how multivariate pattern classification approaches offer an advantageous framework for identifying emotion-specific biomarkers and for testing predictions of theoretical models of emotion. Based on initial studies using multivariate pattern classification, we suggest that (...) central and autonomic nervous system activity can be reliably decoded into distinct emotional states. Finally, we consider future directions in applying pattern classification to understand the nature of emotion in the nervous system. (shrink)

John Dewey wished to place development of the ability to think at the core of school education. The kind of thinking that Dewey had in mind was based on his conception of scientific inquiry. Matthew Lipman was likewise committed to an education centred on thinking, but he claimed that we should turn to philosophy rather than to science in order to secure this end. In his view, philosophy has a stronger claim to this mantle than does science, or any other (...) subject, when it is appropriately reconstructed and taught. He developed various arguments to that effect, but the one considered here is that philosophical thinking has a generic character that especially suits it for the role. I examine this argument to see how compelling a case it makes for the inclusion of philosophy in the school curriculum. (shrink)

Ethicists generally agree that there are supererogatory acts, which are morally good, but not morally obligatory. It is sometimes claimed that, in addition to supererogatory acts, there are suberogatory acts, which are morally bad, but not morally impermissible. According to Julia Driver (1992), the distinction between impermissible acts and suberogatory acts is legitimate and unjustly neglected by ethicists. She argues that certain cases are best explained in terms of the suberogatory. Hallie Rose Liberto (2012) denies the suberogatory on the grounds (...) that Driver's cases can be explained without invoking it. In order to make good on this claim, Liberto suggests an account of moral impermissibility that purportedly eliminates the need to posit suberogatory acts. We defend the suberogatory. Our defense is twofold. First, we argue that Liberto's account of moral impermissibility is dubious. Second, we attempt to show that it is possible to construct an argument against the supererogatory that is exactly analogous to Liberto's argument against the suberogatory. The upshot is that if the suberogatory is denied for the reasons that Liberto suggests, then the supererogatory should be denied as well. Few ethicists, however, are willing to deny the supererogatory. (shrink)

The dominance of technological paradigms within psychiatry creates moral and ethical tensions over how to engage with the interpersonal narratives of those experiencing mental distress. This paper argues that such paradigms are poorly suited for fostering principled responses to human suffering, and proposes an alternative approach that considers a view of relationships based in feminist theories about the nature of caring. Four primary characteristics are presented which distinguish caring from technological paradigms: a concern with the particular nature of contexts, embodied (...) practice, the dialogical basis of caring and the existential basis of caring. From this we explore the role of the moral imagination and our ability, through narrative, to acknowledge, engage with and bear witness to the injustices that shape the lives of those who suffer. This, we argue, is at the heart of caring. Clinical implications are discussed, including an exposition of the importance of narrative in recovery from trauma and distress. Narrative Psychiatry, The Sanctuary Model of care, and Soteria, are outlined as examples of this type of practice. (shrink)

Conceptualisation and reasoning involve intellectual operations that can and should be taught. This paper identifies pairs of basic operations in reasoning and conceptualisation that are comparable to the basic operations of arithmetic and just as important. Examples are provided to illustrate how these operations may be introduced in the classroom.

Henriksen et al. use phenomenology as a tool to clarify the status of what they regard as the abnormal experiences of the condition called schizophrenia. This reveals phenomenology as a method of detailed scrutiny of these experiences to establish a theory about them in terms of the “dissolution of certain structures of self-consciousness” and “morbid objectification of inner speech”. Our commentary is in two parts. In the first, we set out a contrasting view of phenomenology, and its use in madness.1 (...) In the second, we exemplify this use of phenomenology and the meaningful nature of voices through evidence that links.. (shrink)

This article provides a biographical overview of the life of the Venerable Lokanatha (1897?1966), who was born in Italy as Salvatore Cioffi and raised in Brooklyn, New York. After converting to Buddhism in his late-twenties, Lokanatha travelled to Burma, took ordination as a monk, and began a remarkable 40 year career as a writer, lecturer, organizer, and Buddhist missionary throughout South Asia and the world. Beyond biography, Lokanatha and the various responses to him are contextualized within the different cultural spheres (...) in which he operated, from the anti-colonial Buddhist revival in Burma to the mocking indifference Lokanatha found in the United States. Scholarship on modern Buddhism, particularly recent work on U Dhammaloka, is used to situate Lokanatha's life and its facets of conservative reformer and transnational actor. Finally, an account of the source material used to reconstruct the life of Lokanatha is employed to offer practical methodological explanations for his absence from conventional narratives of modern Buddhism and what his inclusion along with other figures might mean in the future.

This paper shows that the non-Boolean logic of quantum measurements is more naturally represented by a relatively new 4-operation system of Boolean fractions—conditional events—than by the standard representation using Hilbert Space. After the requirements of quantum mechanics and the properties of conditional event algebra are introduced, the quantum concepts of orthogonality, completeness, simultaneous verifiability, logical operations, and deductions are expressed in terms of conditional events thereby demonstrating the adequacy and efficacy of this formulation. Since conditional event algebra is nearly Boolean (...) and consists merely of ordered pairs of standard events or propositions, quantum events and the so-called “superpositions” of states need not be mysterious, and are here fully explicated. Conditional event algebra nicely explains these non-standard “superpositions” of quantum states as conjunctions or disjunctions of conditional events, Boolean fractions, but does not address the so-called “entanglement phenomena” of quantum mechanics, which remain physically mysterious. Nevertheless, separating the latter phenomena from superposition issues adds clarity to the interpretation of quantum entanglement, the phenomenon of influence propagated at faster than light speeds. With such treacherous possibilities present in all quantum situations, an observer has every reason to be completely explicit about the environmental–instrumental configuration, the conditions present when attempting quantum measurements. Conditional event algebra allows such explication without the physical and algebraic remoteness of Hilbert space. (shrink)

Over forty years ago, the American philosopher and educationalist began work on what was to become a series of philosophical novels for children. As time went on, he also constructed accompanying teacher resources together with colleagues. The most popular of these works were designed for primary education and constitute what came to be known as the IAPC Curriculum for the younger years. The influence of Lipman has been immense. He taught us that philosophy is not beyond the reach of primary (...) school children when appropriately presented; that the questions of philosophy are germane to all primary school subjects; and that philosophy can be used to encourage thinking across the curriculum. Influential and instructive as these materials have been, however, they do not constitute a curriculum in the sense in which that is generally understood in school education. This paper explores both the strengths and limitations of Lipman’s pioneering effort from the viewpoint of curriculum construction in order to see what lessons can be leaned. (shrink)

In this volume philosophers from throughout the Asia-Pacific region discuss a wide range of topics related to the development of democratic values and ways of life. The papers explore ideas, values and practices related to democracy from the different perspectives of the great religious and philosophical traditions of Asia, as well as considering both philosophical issues and the place of philosophy in a democratic society. While the contributors represent different philosophical traditions, they are connected through a common concern with humanity, (...) a belief in the value of philosophical inquiry and scholarship and by a commitment to the value of philosophy education in building and sustaining democracy.

The norms associated with HP Grice’s cooperative principle focus on exchange of information and require considerable extension in order to capture the presiding features of discourse that attempts to inquire into a problem or an issue. These features are revealed by looking at the case of collaborative philosophical inquiry. Although it is a special case, the findings have widespread implications for education. When teachers venture beyond the kind of informative discourse that has traditionally monopolised verbal exchange in the classroom and (...) engage in collaborative inquiry-based teaching, they need to attend to the norms that govern such discourse.

At last, we have the scientific evidence that documents the manybiological gender differences that influence learning. Forinstance, girls talk sooner, develop better vocabularies, readbetter, and have better fine motor skills. Boys, on the other hand,have better auditory memory, are better at three-dimensionalreasoning, are more prone to explore, and achieve greater abstractdesign ability after puberty. In this profoundly significant book, author Michael Guriansynthesizes the current knowledge and clearly demonstrates how thisdistinction in hard-wiring and socialized gender differencesaffects how boys and girls learn. (...) Gurian presents a new way toeducate our children based on brain science, neurologicaldevelopment, and chemical and hormonal disparities. The innovationspresented in this book were applied in the classroom and provensuccessful, with dramatic improvements in test scores, during atwo-year study that Gurian and his colleagues conducted in sixMissouri school districts.
