Michael Dummett has claimed that analytic philosophy is distinguished from other schools in its belief that a comprehensive philosophical account of thought can only be attained by developing a philosophical account of language. Dummett himself argues persuasively for the priority-of-Ianguage thesis. This, in effect, metaphilosophical position is of special importance for his more straightforwardly philosophical views, for he holds that philosophical investigations of the concepts of objectivity and reality grow directly out of the philosophy of thought. But I argue that (...) some of what Dummett says about the priority of language over thought is problematic, that there may yet be a serious role for concepts within the theory of meaning, and that Dummett’s failure to acknowledge this role both hobbles his account of linguistic understanding and has deleterious consequences for his discussions of metaphysical realism-robbing him of the resources with which he might have avoided some of his anti-realist conclusions.

Michael Dummett begins The Logical Basis of Metaphysics by noting that most of the work done in analytic philosophy seems disconcertingly remote from any concern with the “deep questions of great import for an understanding of the world” that the non-professional expects it to answer. In part, he says, this is because modern analytic philosophy is founded upon a more penetrating analysis of the general structure of our thoughts than was available to past ages, namely, the apparatus of modern logic, (...) beginning with Frege’s Begriffsschrift in 1879. Analytic philosophers take for granted the principles of semantic analysis embodied in the notation of modern logic. Even if they do not make use of a technical vocabulary, having taken these principles for granted is itself often enough to render their approach opaque to the layperson. Appearances aside, he claims, analytic philosophy is still concerned with the “deep questions.” And, to his credit, Dummett keeps an eye focused on some of the central questions of philosophy, those concerning metaphysical realism, throughout the book.

Cet article soutient que les voitures autonomes sont des robots sociaux qui doivent agir comme des tenants-lieux de leurs propriétaires humains. Pour ne pas esquiver les choix moraux incombant aux utilisateurs humains de ces technologies, on pourrait programmer les véhicules de façon à ce qu’ils puissent se comporter selon différentes théories morales, en permettant aux propriétaires de choisir celle qui a leur préférence. L’article envisage également les implications éthiques d’autres problèmes pratiques liés à la technologie des voitures autonomes.

A three-valued propositional logic is presented, within which the three values are read as ?true?, ?false? and ?nonsense?. A three-valued extended functional calculus, unrestricted by the theory of types, is then developed. Within the latter system, Bochvar analyzes the Russell paradox and the Grelling-Weyl paradox, formally demonstrating the meaninglessness of both.

Bainbridge’s well known “Ironies of Automation” Analysis, design and evaluation of man–machine systems. Elsevier, Amsterdam, pp 129–135, 1983. https://doi.org/10.1016/B978-0-08-029348-6.50026-9) laid out a set of fundamental criticisms surrounding the promises of automation that, even 30 years later, remain both relevant and, in many cases, intractable. Similarly, a set of ironies in technologies for sensor driven self-quantification is laid out here, spanning from instrumental problems in human factors design to much broader social problems. As with automation, these ironies stand in the way (...) of many of the promised benefits of these wearable technologies. It is argued here that without addressing these ironies now, the promises of wearables may not come to fruition, and instead users may experience outcomes that are opposite to those which the designers seek to afford, or, at the very least, those which consumers believe they are being offered. This paper describes four key ironies of sensor driven self-quantification: know more, know better versus no more, no better; greater self-control versus greater social control; well-being versus never being well enough; more choice versus erosion of choice.

Objectives: To discover the current state of opinion and practice among doctors in Victoria, Australia, regarding end-of-life decisions and the legalisation of voluntary euthanasia. Longitudinal comparison with similar 1987 and 1993 studies.Design and participants: Cross-sectional postal survey of doctors in Victoria.Results: 53% of doctors in Victoria support the legalisation of voluntary euthanasia. Of doctors who have experienced requests from patients to hasten death, 35% have administered drugs with the intention of hastening death. There is substantial disagreement among doctors concerning the (...) definition of euthanasia.Conclusions: Disagreement among doctors concerning the meaning of the term euthanasia may contribute to misunderstanding in the debate over voluntary euthanasia. Among doctors in Victoria, support for the legalisation of voluntary euthanasia appears to have weakened slightly over the past 17 years. Opinion on this issue is sharply polarised. (shrink)

Primordial emotions are the subjective element of the instincts which are the genetically programmed behaviour patterns which contrive homeostasis. They include thirst, hunger for air, hunger for food, pain and hunger for specific minerals etc.There are two constituents of a primordial emotion—the specific sensation which when severe may be imperious, and the compelling intention for gratification by a consummatory act. They may dominate the stream of consciousness, and can have plenipotentiary power over behaviour.It is hypothesized that early in animal evolution (...) complex reflex mechanisms in the basal brain subserving homeostatic responses, in concert with elements of the reticular activating system subserving arousal, melded functionally with regions embodied in the progressive rostral development of the telencephalon. This included the emergent limbic and paralimbic areas, and the insula. This phylogenetically ancient organization subserved the origin of consciousness as the primordial emotion, which signalled that the organisms existence was immediately threatened. Neuroimaging confirms major activations in regions of the basal brain during primordial emotions in humans. The behaviour of decorticate humans and animals is discussed in relation to the possible existence of primitive awareness.Neuroimaging of the primordial emotions reveals that rapid gratification of intention by a consummatory act such as ingestion causes precipitate decline of both the initiating sensation and the intention. There is contemporaneous rapid disappearance of particular regions of brain activation which suggests they may be part of the jointly sufficient and severally necessary activations and deactivations which correlate with consciousness [Crick, F. & Koch, C. . A framework for consciousness. NatureNeuroscience,6, 119–126]. (shrink)

Lexical Semantics is about the meaning of words. Although obviously a central concern of linguistics, the semantic behaviour of words has been unduly neglected in the current literature, which has tended to emphasize sentential semantics and its relation to formal systems of logic. In this textbook D. A. Cruse establishes in a principled and disciplined way the descriptive and generalizable facts about lexical relations that any formal theory of semantics will have to encompass. Among the topics covered in depth are (...) idiomaticity, lexical ambiguity, synonymy, hierarchical relations such as hyponymy and meronymy, and various types of oppositeness. Syntagmatic relations are also treated in some detail. The discussions are richly illustrated by examples drawn almost entirely from English. Although a familiarity with traditional grammar is assumed, readers with no technical linguistic background will find the exposition always accessible. All readers with an interest in semantics will find in this original text not only essential background but a stimulating new perspective on the field. (shrink)

In a published exchange, Richard Robinson and Roy A. Sorenson debate the matter of whether begging the question is a fallacy; Robinson thinks it is not, but Sorenson argues that it is. Norman Ten attempts to resolve this debate by making a distinction between begging the question and fallaciously begging the question. While Teng is right to note that Robinson and Sorenson are talking past each other, he incorrectly diagnoses the source of this miscommunication. In this paper, then, I offer (...) what I take to be a more illuminating distinction 3; viz. that between logical and rhetorical fallacies 3; and employ that distinction to resolve the debate.

Recently, commentators close to and within the UK government have claimed that patient choice can increase equity in the context of the National Health Service. This article critically examines the basis for this claim through analysis of recent speeches and publications authored by secretaries of state for health and their policy advisers. It is concluded that this claim has not developed prospectively from an analysis of the causes of healthcare inequity, or even with a consistent normative definition of equity. The (...) limited justification that is “framed in causal explanations” of inequity has suffered from an apparent disregard of the available evidence. (shrink)

Traditional explanations of multistable visual phenomena (e.g. ambiguous figures, perceptual rivalry) suggest that the basis for spontaneous reversals in perception lies in antagonistic connectivity within the visual system. In this review, we suggest an alternative, albeit speculative. explanation for visual multistability - that spontaneous alternations reflect responses to active, programmed events initiated by brain areas that integrate sensory and non-sensory information to coordinate a diversity of behaviors. Much evidence suggests that perceptual reversals are themselves more closely related to the expression (...) of a behavior than to passive sensory responses: (1) they are initiated spontaneously, often voluntarily, and are influenced by subjective variables such as attention and mood; (2) the alternation process is greatly facilitated with practice and compromised by lesions in non- visual cortical areas; (3) the alternation process has temporal dynamics similar to those of spontaneously initiated behaviors; (4) functional imaging reveals that brain areas associated with a variety of cognitive behaviors are specifically activated when vision becomes unstable. In this scheme, reorganizations of activity throughout the visual cortex, concurrent with perceptual reversals, are initiated by higher, largely non- sensory brain centers. Such direct intervention In the processing of the sensory input by brain structures associated with planning and motor programming might serve an important role in perceptual organization, particularly in aspects related to selective attention.

Objections to the use of assistive technologies in elite sports are generally raised when the technology in question is perceived to afford the user a potentially “unfair advantage,” when it is perceived as a threat to the purity of the sport, and/or when it is perceived as a precursor to a slippery slope toward undesirable changes in the sport. These objections rely on being able to quantify standards of “normal” within a sport so that changes attributed to the use of (...) assistive technology can be judged as causing a significant deviation from some baseline standard. This holds athletes using assistive technologies accountable to standards that restrict their opportunities to achieve greatness, while athletes who do not use assistive technologies are able to push beyond the boundaries of these standards without moral scrutiny. This paper explores how constructions of fairness and “normality” impact athletes who use assistive technology to compete in a sporting venue traditionally populated with “able-bodied” competitors. It argues that the dynamic and obfuscated construction of “normal” standards in elite sports should move away from using body performance as the measuring stick of “normal,” toward alternate forms of constructing norms such as defining, quantifying, and regulating the mechanical actions that constitute the critical components of a sport. Though framed within the context of elite sports, this paper can be interpreted more broadly to consider problems with defining “normal” bodies in a society in which technologies are constantly changing our abilities and expectations of what normal means.

Revisiting African philosophy’s classic questions, D. A. Masolo advances understandings of what it means to be human—whether of African or other origin. Masolo reframes indigenous knowledge as diversity: How are we to understand the place and structure of consciousness? How does the everyday color the world we know? Where are the boundaries between self and other, universal and particular, and individual and community? From here, he takes a dramatic turn toward Africa’s current political situation and considers why individual rights and (...) freedoms have not been recognized, respected, demanded, or enforced. Masolo offers solutions for containing socially destructive conduct and antisocial tendencies by engaging community. His unique thinking about community and the role of the individual extends African philosophy in new, global directions. (shrink)
