This long-awaited book replaces Hughes and Cresswell's two classic studies of modal logic: _An Introduction to Modal Logic_ and _A Companion to Modal Logic_. _A New Introduction to Modal Logic_ is an entirely new work, completely re-written by the authors. They have incorporated all the new developments that have taken place since 1968 in both modal propositional logic and modal predicate logic, without sacrificing tha clarity of exposition and approachability that were essential features of their earlier works. The book (...) takes readers from the most basic systems of modal propositional logic right up to systems of modal predicate with identity. It covers both technical developments such as completeness and incompleteness, and finite and infinite models, and their philosophical applications, especially in the area of modal predicate logic.

It is necessary that, if the world is divided into nations, conflicts should arise in which there is no strong argument against terrorism or repression. By a strong argument I mean one that would sway all minds not blindly partisan, without moral commitments that are unusual or outlandish in the modern world and with as much aversion to violence as most people have. So I do not here consider, because it is unusual, heroic and absolute pacifism, much as I respect (...) it; on the other hand I do mention Christian moral objections applying specially to terrorism because it seems somewhat outlandish even now to ignore the Christian element in our tradition.

Moshe Tati, a sanitation worker in Jerusalem, was among the first of more than a thousand mortally sick Israelis who signed up for illicit and clandestine ‘transplant tour’ packages that included: travel to an undisclosed foreign and exotic setting; five-star hotel accommodation; surgery in a private hospital unit; a ‘fresh’ kidney purchased from a perfect stranger trafficked from a third country. Although Tati’s holiday turned into a nightmare and he had to be emergency air-lifted from a rented transplant unit in (...) a private hospital in Adana, Turkey back to Israel, Moshe became a poster-boy of transplant tourism for the next decade. João Cavalcanti was among the first of 38 residents of the slums of Recife recruited by retired military Captain Ivan da Silva and his sidekick Captain Gadddy Tauber to travel to Durban, South Africa to provide a spare kidney to an Israeli transplant tourist in Durban. This article examines the logics and practices through which kidney buyers and kidney sellers, organs brokers, surgeons and their accessories convince themselves that they are engaged in an illegal but still mutually beneficial ‘medical-recreational’ adventure, an ‘extreme medical sport’ of sorts. While life, health and survival motivate ‘transplant tourism’, a euphemism for human trafficking in spare body parts, the freedom to roam, mobility, is an essential feature of transplant tours for kidney buyers and kidney sellers.

Terminological debates are often circular and unproductive, so it is a pleasure to investigate the terminology of LeRon Shults, who argues with clarity, defines his terms, and offers reasons for preferring one term over another. I would not, however, waste the readers' time if my aim were merely to challenge some of Shults's nomenclature. When one sets out, as does Shults, to intervene in the process of theogonic reproduction, terminological and metaphorical choices matter a great deal insofar as the semiotic (...) tools one deploys carry emotional and affective baggage that can deeply influence the efficacy of the hoped-for intervention. As I argue below, there is much to commend... (shrink)

The Neglected Argument for the Reality of God is something of a Rorschach test for scholars of Peirce.1 Some see a creative presentation of his mature philosophy of inquiry, while others find evidence that Peirce was unable to free himself of his conservative religious milieu. As the editors of The Essential Peirce collection noted: “Whether this paper is an elaboration of or an offense against pragmatism is an unsettled question.”2 The primary import of the essay, I contend, is not to (...) defend God’s reality but rather to highlight continuities between religion and science. In doing so, Peirce aims to show theologians how they might better do their jobs. My aim in this paper is to take Peirce’s advice seriously and.. (shrink)

Conservatism is part of the legacy of the pragmatic tradition’s deep respect for the continuity of inquiry. Despite his commitment to open and fallible inquiry, Charles Sanders Peirce remained his entire life a kind of religious conservative, arguing for a community that would be, in Douglas Anderson’s words “conservative in its practice and liberal in its theory.”1 The following argument is largely about Peirce’s career-long struggle to reconcile conservative practice and liberal theory, especially as they impact his philosophy of inquiry. (...) He offers hints at a solution, what I am calling his “hopeful monster,” but remains ambivalent about this strategy, as should we, his contemporary readers. As described below, a... (shrink)

LeRon Shults and Palgrave MacMillan are happy to announce the arrival of Postpartum Theology!Shults has changed his guiding metaphors during the short interval between the publication of Iconoclastic Theology: Gilles Deleuze and the Secretion of Atheism and Theology After the Birth of God. While Iconoclastic Theology emphasized the iconoclastic potential of theology with the help of Deleuze’s well-struck hammer blows, Theology After the Birth of God adopts natal imagery. The gods, Shults argues, were conceived in the human mind, born into (...) the world as a result of human cognitive errors, and continue to be borne in diverse cultures. Prophets who have announced the death of God have little impacted our continued... (shrink)

While scholars of religion have explored Peirce's philosophy of religion and extensively mined his groundbreaking work in semiotics, other aspects of Peirce's religious and theological thought have been largely ignored within religious studies. In particular, Peirce's theory of inquiry offers several potentially important insights that scholars of religion would do well to consider more fully. These insights are best realized through conceiving of religious participation as a form of inquiry, continuous with but importantly different from other forms of human inquiry. (...) By focusing on the dynamics of belief, doubt, and inquiry that pervade all human endeavors, religious participation can be conceptualized as a... (shrink)

I initiate the concept of ‘making-remote’ to capture various strategies for representing the human in late Palaeolithic cave art. Drawing out the role of remoteness within phenomenological accounts of perception (Husserl and Merleau-Ponty), as well as offering an analysis of a wide range of archaeological evidence, I argue that realism does not capture the specificity of these human representations. In contrast to naturalistic animal representations, humans are consistently represented with a high degree of abstraction e.g., schematisation and abbreviation. I also (...) argue for a site-specific distinction between deep caves and rock-shelters. Following Bourdier (2010) and Pinçon (2012), art at sites such as Roc-aux-Sorciers is best understood as stylised ‘public art’. Meanwhile, the highly expressive and realist art of La Marche is domestic in contrast to the exclusively symbolic art of deep caves. In conclusion I argue that ‘making-remote’ in cave art’s human representations exhibits complex relations to self and others. (shrink)

A general account of modeling in physics is proposed. Modeling is shown to involve three components: denotation, demonstration, and interpretation. Elements of the physical world are denoted by elements of the model; the model possesses an internal dynamic that allows us to demonstrate theoretical conclusions; these in turn need to be interpreted if we are to make predictions. The DDI account can be readily extended in ways that correspond to different aspects of scientific practice.

The mental health crisis and loneliness epidemic have sparked a growing interest in leveraging artificial intelligence (AI) and chatbots as a potential solution. This report examines the benefits and risks of incorporating chatbots in mental health treatment. AI is used for mental health diagnosis and treatment decision-making and to train therapists on virtual patients. Chatbots are employed as always-available intermediaries with therapists, flagging symptoms for human intervention. But chatbots are also sold as stand-alone virtual therapists or as friends and lovers. (...) There is evidence that these uses of AI and chatbots can provide better quality service, improve accessibility, and lower costs. The systems can reduce the stigma and shame of sharing their problems and leverage a mass of biometric and behavioral data to supplement self-reports. As the systems' intelligence rapidly improves, they will need to be rigorously tested for the accuracy and precision of their diagnoses and the quality of their interactions with patients. As chatbots become indistinguishable from humans and leverage their superhuman capacity to detect affect and draw on knowledge of a patient’s life, patients will be drawn to attribute personality to and relationship with the chatbot. Consequently, it will be essential to study what the “therapeutic alliance” with an actual human counselor provides and the risks of patients attributing such a relationship to a one-sided or “parasocial” relationship.

Proprioception is a crucial sensory modality involved in the control and regulation of coordinated movements and in motor learning. However, the extent to which proprioceptive acuity is influenced by local muscle fatigue is obscured by methodological differences in proprioceptive and fatiguing protocols. In this study, we used high resolution kinematic measurements provided by a robotic device, as well as both frequency and time domain analysis of signals captured via surface electromyography (sEMG) to examine the effects of local muscle fatigue on (...) wrist proprioceptive acuity in 16 physically and neurologically healthy young adults. To this end, participants performed a flexion/extension ipsilateral joint position matching test (JPM), after which a high-resistive robotic task was used to induce muscle fatigue of the flexor carpi radialis (FCR) muscle. The JPM test was then repeated in order to analyze potential changes in proprioceptive acuity. Results indicated that the fatigue protocol had a significant effect on movements performed in flexion direction, with participants exhibiting a tendency to undershoot the target before the fatigue protocol (-1.218°), but overshooting after the fatigue protocol (0.587°). In contrast, in the extension direction error bias values were similar before and after the fatigue protocol as expected (pre = -1.852°, post = -1.237°) and reflected a tendency to undershoot the target. Moreover, statistical analysis indicated that movement variability was not influenced by the fatigue protocol or movement direction. In sum, results of the present study demonstrate that an individual’s estimation of wrist joint displacement (i.e., error bias), but not precision (i.e., variability), is affected by muscular fatigue in a sample of neurologically and physically healthy adults.

Sandia National Laboratories, located in Albuquerque, New Mexico, was originally a part of Los Alamos Laboratory. In 1949, AT&T agreed to manage Sandia, which they did for the next 44 years. During those Cold War years, Sandia was the prime weapons engineering laboratory for Los Alamos and Lawrence Livermore. As such, it bore prime responsibility for designing and adapting nuclear weapons for the military services' delivery systems, and ensuring the safety and reliability of the stockpile. The Labs' history has been (...) unevenly documented, hindered by the secret nature of its work and the desire of management to maintain a low public profile. There have been three history programs at Sandia: a restricted history published internally in 1963; another history program in the early 1980s that resulted in a history of the Labs' first decade; and the current history program dating from the mid-1990s, which has published a general history and several monographs. This article discusses the challenges and problems inherent in documenting the history of a national weapons laboratory during the last 50 years. (shrink)

William Hughes's Critical Thinking, revised and updated by Jonathan Lavery, is a comprehensive and accessible introduction to the essential skills required to make strong arguments. Hughes and Lavery give a thorough treatment of such traditional topics as deductive and inductive reasoning, logical fallacies, the importance of inference, how to recognize and avoid ambiguity, and how to assess what is or is not relevant to an argument. The authors also cover less traditional topics such as special concerns to keep (...) in mind when reasoning about ethical matters, and how the nature of a language can affect the structure of an argument. In addition to covering basic concepts for analyzing and assessing arguments, the text also has two chapters that are designed to help students write argumentative essays. Last but not least, Critical Thinking includes a selection of logical paradoxes and puzzles that are as entertaining as they are enlightening. For the fifth edition particular attention has been paid to the needs of Canadian students and instructors. (shrink)

BackgroundDecision-making in end-stage dementia is a complex process involving medical, social, legal and ethical issues. In ESD, the person suffers from severe cognitive problems leading to a loss of capacity to decide matters regarding health and end-of-life issues. The decisional responsibility is usually passed to clinicians and relatives who can face significant difficulty in making moral decisions, particularly in the presence of life-threatening swallowing problems.AimThis study aimed to understand the decision-making processes of clinical teams and relatives in addressing life-threatening swallowing (...) difficulties in ESD in long-term care in Malta.MethodThe study followed a qualitative approach where six case studies, involving six different teams and relatives of six different patients, were interviewed retrospectively to understand their decision-making in connection with the management of swallowing difficulties in ESD. Data were collected through semistructured interviews with each stakeholder. All data were transcribed and subjected to thematic analysis.ResultsFour themes were identified: the vulnerability of patients in dementia decision-making; the difficult role of relatives in decision-making; the decisional conflict between aggressive care through tube feeding versus oral comfort feeding; a consensus-building decision-making process as ideal to facilitate agreement and respect for patient’s dignity.ConclusionDecision-making to manage swallowing difficulties in ESD is a challenging process, which involves an interpretation of personal values, beliefs, patient preferences, care needs and clinical practice. Better communication between clinicians and relatives in dementia helps promote agreement between stakeholders leading to a care plan that respects the dignity of patients at their end of life.

6 and 14 recently proposed taxonomies that distinguish between four processing states, based on bottom-up stimulus strength and top-down attentional amplification. The aim of the present study was to empirically test these processing states using the priming paradigm. Our results showed that attention and stimulus strength significantly modulated priming effects: either receiving top-down attention or possessing sufficient bottom-up strength was a prerequisite for a stimulus to elicit priming. When both top-down attention and sufficient bottom-up strength were present, the priming effect (...) was boosted. The origins of the observed priming effects also varied between different processing states. We can conclude that our empirical study using the priming paradigm confirmed the presence of four processing states, which displayed a differential pattern of response priming effects and differential origins of the response priming effects.

Focusing on a discussion by Ruddich and Stassen of the ?Remarks on Frazer's Golden Bough?, this paper shows that some of the usual criticisms made by sociologists of Wittgenstein are misplaced. He does not reject causal explanations of beliefs and actions and replace them with some other form of explanation, but dismisses the idea that any explanation is called for here. His argument that the origin of the desire to explain beliefs is to be found in a misconceived parallel between (...) science and magic is explained and discussed. (shrink)

Drawing on resources from both the Analytical and Continental traditions, Form and World argues that a comprehension of Kant's aesthetics is necessary for grasping the scope and force of his epistemology. Fiona Hughes draws on phenomenological and aesthetic resources to bring out the continuing relevance of Kant's project. One of the difficulties faced in reading the Critique of Pure Reason is finding a way of reading the text as one continuous discussion. This book offers a reading at each stage (...) of Kant's epistemological argument, showing how various elements of Kant's argument, often thought of as extraneous or indefensible, can be integrated. This incisive study, arguing for the centrality of aesthetics in philosophy, and within experience in general, challenges a blind spot in the Anglo-American tradition of philosophy and will contribute to a growing interest in the general significance of aesthetic culture.

Hyman (1999, 2006) argues that knowledge is best conceived as a kind of ability: S knows that p iff S can φ for the reason that p. Hyman motivates this thesis by appealing to Gettier cases. I argue that it is counterexampled by a certain kind of Gettier case where the fact that p is a cause of the subject’s belief that p. One can φ for the reason that p even if one does not know that p. So knowledge (...) is not best conceived as an ability of this kind. (shrink)

Recently it has been increasingly popular to argue that knowledge is the norm of belief. I present an argument against this view. The argument trades on the epistemic situation of the subject in the bad case. Notably, unlike with other superficially similar arguments against knowledge norms, knowledge normers preferred strategy of appealing to the distinction between permissibility and excusability cannot help them to rebut this argument.
