In this paper, we make the case that a person who is considering or has already made a decision that appears seriously harmful to that person should in some cases be judged incapable of making that...

Neil Tennant presents an original logical system with unusual philosophical, proof-theoretic, metalogical, computational, and revision-theoretic virtues. Core Logic is the first system that ensures both relevance and adequacy for the formalization of all mathematical and scientific reasoning.

If a person is competent to consent to a treatment, is that person necessarily competent to refuse the very same treatment? Risk relativists answer no to this question. If the refusal of a treatment is risky, we may demand a higher level of decision-making capacity to choose this option. The position is known as asymmetry. Risk relativity rests on the possibility of setting variable levels of competence by reference to variable levels of risk. In an excellent 2016 article inJournal of (...) Medical Ethics(JME), Rob Lawlor defends asymmetry of this kind by defending risk relativity, using and developing arguments and approaches found in earlier work such as that of Wilks. He offers what we call the two-scale approach: a scale of risk is to be used to set a standard of competence on a scale of decision-making difficulty. However, can this be done in any rational way? We argue it cannot, and in this sense, and to this extent, risk relativity is a nonsense. (shrink)

Noam Chomsky is one of the leading intellectual figures of modern times. He has had a major influence on linguistics, psychology and philosophy, and a significant effect on many other disciplines, from anthropology to mathematics, education to literary criticism. In this rigorous yet accessible account of Chomsky's work and influence, Neil Smith analyses Chomsky's key contributions to the study of language and the study of mind. He gives a detailed exposition of Chomsky's linguistic theorizing, discusses the psychological and philosophical (...) implications of Chomsky's work, and argues that he has fundamentally changed the way we think of ourselves, gaining a position in the history of ideas on a par with that of Darwin or Descartes. This second edition has been thoroughly updated to account for Chomsky's most recent work, including his continued contributions to linguistics, his further discussion on evolution, and his extensive work on the events of September 11th, 2001.

This paper explores connections between theories of morality and theories of properties. It argues that (1) moral realism is in tension with predicate, class and mereological nominalism; (2) moral non-naturalism is incompatible with standard versions of resemblance nominalism, immanent realism and trope theory; and (3) the standard semantic arguments for property realism do not support moral realism. I also raise doubts about trope-theoretic explanations of moral supervenience and argue against one version of the principle that we should accept theories that (...) maintain neutrality. (shrink)

Heidegger's ontological theories, his observations about liberalism and fascism, and his evaluation of Being are three premises of an argument for fascism. The ontological premise is that integrated wholes and instruments or objects of will are ontologically superior, as Being and Time suggests in discussing Being‐a‐whole and using tools. The social premise is that fascist societies are wholes integrated by dictatorial will, while liberal societies are looser aggregates of free individuals, as Heidegger describes in his 1930s seminars. The evaluative premise, (...) shared with the medieval tradition and expressed in his notebook remarks about war, is that ontological superiority makes things better. The conclusion that fascism is better than liberalism should be rejected along with the evaluative premise. (shrink)

In part one, I identify the core logical structure of the precautionary principle and distinguish it from the various key concepts that appear in the many different formulations of the principle. I survey these concepts and suggest a program of further conceptual analysis. In part two, I examine a particular version of the precautionary principle dubbed “the catastrophe principle” and criticize it in light of its similarities to the principle at work in Pascal’s Wager. I conclude with some suggestions for (...) advocates of the precautionary principle who wish their formulation to avoid the pitfalls confronting the catastrophe principle. (shrink)

Visual narratives like comics involve a range of complex cognitive operations in order to be understood. The Parallel Interfacing Narrative‐Semantics (PINS) Model integrates an emerging literature showing that comprehension of wordless image sequences balances two representational levels of semantic and narrative structure. The neurocognitive mechanisms that guide these processes are argued to overlap with other domains, such as language and music.

In this paper I argue that the explanationist argument in favour of moral realism fails. According to this argument, the ability of putative moral properties to feature in good explanations provides strong evidence for, or entails, the metaphysical claims of moral realism. Some have rejected this argument by denying that moral explanations are ever good explanations. My criticism is different. I argue that even if we accept that moral explanations are (sometimes) good explanations the metaphysical claims of realism do not (...) follow. (shrink)

The motivation for Core Logic is explained. Its system of proof is set out. It is then shown that, although the system has no Cut rule, its relation of deducibility obeys Cut with epistemic gain.

Presentists standardly conform to the eternalist’s paradigm of treating all cases of property-exemplification as involving a single relation of instantiation. This, we argue, results in a much less parsimonious and philosophically explanatory picture than is possible if other alternatives are considered. We argue that by committing to primitive past and future tensed instantiation ties, presentists can make gains in both economy and explanatory power. We show how this metaphysical picture plays out in cases where an individual exists to partake in (...) facts about its past and future, and also in cases where that individual no longer exists, and proxies (or surrogates) for that thing must be found.

Tacit knowledge is the form of implicit knowledge that we rely on for learning. It is invoked in a wide range of intellectual inquiries, from traditional academic subjects to more pragmatically orientated investigations into the nature and transmission of skills and expertise. Notwithstanding its apparent pervasiveness, the notion of tacit knowledge is a complex and puzzling one. What is its status as knowledge? What is its relation to explicit knowledge? What does it mean to say that knowledge is tacit? Can (...) it be measured? Recent years have seen a growing interest from philosophers in understanding the nature of tacit knowledge. Philosophers of science have discussed its role in scientific problem-solving; philosophers of language have been concerned with the speaker's relation to grammatical theories; and phenomenologists have attempted to describe the relation of explicit theoretical knowledge to a background understanding of matters that are taken for granted. This book seeks to bring a unity to these diverse philosophical discussions by clarifying their conceptual underpinnings. In addition the book advances a specific account of tacit knowledge that elucidates the importance of the concept for understanding the character of human cognition, and demonstrates the relevance of the recommended account to those concerned with the communication of expertise. The book will be of interest to philosophers of language, epistemologists, cognitive psychologists and students of theoretical linguistics. (shrink)

This book asks whether there any limits to the sorts of religious considerations that can be raised in public debates, and if there are, by whom they are to be identified. Its starting point is the work of Richard Rorty, whose pragmatic pluralism leads him to argue for a politically motivated anticlericalism rather than an epistemologically driven atheism. Rather than defend Rorty’s position directly, Gascoigne argues for an epistemological stance he calls ‘Pragmatist Fideism’. The starting point for this exercise in (...) what Rorty calls ‘Cultural Politics’ is an acknowledgement that one must appeal to both secularists and those with religious commitments. In recent years ‘reformed’ epistemologists have aimed to establish a parity of epistemic esteem between religious and perceptual beliefs by exploiting an analogy in respect of their mutual vulnerability to sceptical challenges. Through an examination of this analogy, and in light of Wittgenstein’s On Certainty, this book argues that understood correctly the ‘parity’ argument in fact lends epistemological support to the argument that religious considerations should not be raised in public debate. The political price paid—paying the price of politics—is worth it: the religious thinker is provided with a good reason for maintaining that their practices and beliefs are not undermined by other forms of religious life.

We begin with a brief explanation of our proof-theoretic criterion of paradoxicality—its motivation, its methods, and its results so far. It is a proof-theoretic account of paradoxicality that can be given in addition to, or alongside, the more familiar semantic account of Kripke. It is a question for further research whether the two accounts agree in general on what is to count as a paradox. It is also a question for further research whether and, if so, how the so-called Ekman (...) problem bears on the investigations here of the intensional paradoxes. Possible exceptions to the proof-theoretic criterion are Prior’s Theorem and Russell’s Paradox of Propositions—the two best-known ‘intensional’ paradoxes. We have not yet addressed them. We do so here. The results are encouraging. §1 studies Prior’s Theorem. In the literature on the paradoxes of intensionality, it does not enjoy rigorous formal proof of a Gentzenian kind—the kind that lends itself to proof-theoretic analysis of recondite features that might escape the attention of logicians using non-Gentzenian systems of logic. We make good that lack, both to render the criterion applicable to the formal proof, and to see whether the criterion gets it right. Prior’s Theorem is a theorem in an unfree, classical, quantified propositional logic. But if one were to insist that the logic employed be free, then Prior’s Theorem would not be a theorem at all. Its proof would have an undischarged assumption—the ‘existential presupposition’ that the proposition $$\forall p(Qp\!\rightarrow \!\lnot p)$$ ∀ p ( Q p → ¬ p ) exists. Call this proposition $$\vartheta$$ ϑ. §2 focuses on $$\vartheta$$ ϑ. We analyse a Priorean reductio of $$\vartheta$$ ϑ along with the possibilitate $$\Diamond \forall q(Qq\!\leftrightarrow \!(\vartheta \!\leftrightarrow \! q))$$ ◊ ∀ q ( Q q ↔ ( ϑ ↔ q ) ). The attempted reductio of this premise-pair, which is constructive, cannot be brought into normal form. The criterion says we have not straightforward inconsistency, but rather genuine paradoxicality. §3 turns to problems engendered by the proposition $$\exists p(Qp\wedge \lnot p)$$ ∃ p ( Q p ∧ ¬ p ) (call it $$\eta$$ η ) for the similar possibilitate $$\Diamond \forall q(Qq\!\leftrightarrow \!(\eta \!\leftrightarrow \! q))$$ ◊ ∀ q ( Q q ↔ ( η ↔ q ) ). The attempted disproof of this premise-pair—again, a constructive one—cannot succeed. It cannot be brought into normal form. The criterion says the premise-pair is a genuine paradox. In §4 we show how Russell’s Paradox of Propositions, like the Priorean intensional paradoxes, is to be classified as a genuine paradox by the proof-theoretic criterion of paradoxicality. (shrink)

Narratives are an integral part of human expression. In the graphic form, they range from cave paintings to Egyptian hieroglyphics, from the Bayeux Tapestry to modern day comic books (Kunzle, 1973; McCloud, 1993). Yet not much research has addressed the structure and comprehension of narrative images, for example, how do people create meaning out of sequential images? This piece helps fill the gap by presenting a theory of Narrative Grammar. We describe the basic narrative categories and their relationship to a (...) canonical narrative arc, followed by a discussion of complex structures that extend beyond the canonical schema. This demands that the canonical arc be reconsidered as a generative schema whereby any narrative category can be expanded into a node in a tree structure. Narrative “pacing” is interpreted as a reflection of various patterns of this embedding: conjunction, left-branching trees, center-embedded constituencies, and others. Following this, diagnostic methods are proposed for testing narrative categories and constituency. Finally, we outline the applicability of this theory beyond sequential images, such as to film and verbal discourse, and compare this theory with previous approaches to narrative and discourse.

In a series of articles, Terry Horgan and Mark Timmons have argued that Richard Boyd’s defence of moral realism, utilizing a causal theory of reference, fails. Horgan and Timmons construct a twin Earth-style thought experiment which, they claim, generates intuitions inconsistent with the realist account. In their thought experiment, the use of (allegedly) moral terms at a world is causally regulated by some property distinct from that regulating their use here on Earth; nevertheless, Horgan and Timmons claim, it is intuitive (...) that the inhabitants of this world disagree with us in their moral claims. Since any disagreement would be merely verbal were the alleged moral facts identical to or constituted by different natural facts, the identity or constitution claim must be false. I argue that their argument fails. Horgan and Timmons’ thought experiment is underdescribed; when we fill out the details, I claim, we shall see that the challenge to moral realism fades away. I sketch two possible interpretations of the (apparently) moral claims of the inhabitants of moral Twin Earth. On one interpretation, they fail to disagree with us because they actually agree with us; on the other, they fail to disagree with us because they are not moralizers at all. Which interpretation is true, I argue, will depend on the facts that explain the differences between us and the inhabitants of moral twin Earth. (shrink)

Environmental philosophers often conflate the concepts of intrinsic value and moral standing. As a result, individualists needlessly deny intrinsic value to species, while holists falsely attribute moral standing to species. Conceived either as classes or as historical individuals, at least some species possess intrinsic value. Nevertheless, even if a species has interests or a good of its own, it cannot have moral standing because species lack sentience. Although there is a basis for duties toward some species (in terms of their (...) intrinsic value), it is not the one that the holists claim. (shrink)

In a recent article in this journal, Storrs McCall and E.J. Lowe sketch an account of indeterminist free will designed to avoid the luck objection that has been wielded to such effect against event‐causal libertarianism. They argue that if decision‐making is an indeterministic process and not an event or series of events, the luck objection will fail. I argue that they are wrong: the luck objection is equally successful against their account as against existing event‐causal libertarianisms. Like the event‐causal libertarianism (...) their account is meant to supplant, the process view cannot offer a reasons explanation of the agent’s choice itself; that choice is explained by nothing except chance. The agent therefore fails to exercise freedom‐level control over it. (shrink)

The continuing spread and development of electronic data interchange in health care settings is fuelling a significant global debate about the practicality, ethics, and legality of such a practice. The uncertainties implicit in this debate are particularly acute in the context of disease or population groups for whom multidisciplinary, multipleagency teamworking has become acknowledged as the “best practice” for providing effective and timely care or support. The greying of the population is a demographic phenomenon that will have a profound impact (...) on the health care system, social care agencies, and caregivers, and will require a greater degree of service coordination in order to meet the complex care needs of both care-receiver and caregiver.

People report believing weird things: that the Earth is flat, that senior Democrats are subjecting kidnapped children to abuse, and so on. How can people possibly believe things like this? Some philosophers have recently argued for a surprising answer: people don’t believe these things at all. Rather, they mistake their imaginings for beliefs. They are shmelievers, not believers. In this paper, I consider the prospects for this kind of explanation. I argue that some belief reports are simply insincere, and that (...) much of the evidence for shmeliefs can be explained by the content of the beliefs reported, rather than by the attitude people take to them. But some reported beliefs are good candidates for being shmeliefs. I consider how shmeliefs are acquired and sustained, and why they might be harmful despite not being seriously believed. (shrink)

Robert Kane’s libertarian theory is often attacked on the grounds that undetermined self-forming actions are not amenable to contrastive explanation. I propose that we should understand contrastive explanations in terms of an appeal to structuring causes. Doing so reveals that Kane’s claim that there can be no contrastive explanation for self-forming actions is not an unwanted implication of his appeal to indeterminism, but is actually an implication of the fact that the agent’s will is not yet appropriately structured. I then (...) explain how this can assist Kane with the luck objection. (shrink)

Drawn sequences of images, like those in comics and picture stories, are a pervasive and fundamental way that humans have communicated for millennia. Yet, the study of visual narratives has only recently gained traction in Cognitive Science. Here we explore what has held back the study of the cognition of visual narratives, and why researchers should join in scholarship of this ubiquitous aspect of expression.

Cohn's (2013) theory of “Visual Narrative Grammar” argues that sequential images take on categorical roles in a narrative structure, which organizes them into hierarchic constituents analogous to the organization of syntactic categories in sentences. This theory proposes that narrative categories, like syntactic categories, can be identified through diagnostic tests that reveal tendencies for their distribution throughout a sequence. This paper describes four experiments testing these diagnostics to provide support for the validity of these narrative categories. In Experiment 1, participants reconstructed (...) unordered panels of a comic strip into an order that makes sense. Experiment 2 measured viewing times to panels in sequences where the order of panels was reversed. In Experiment 3, participants again reconstructed strips but also deleted a panel from the sequence. Finally, in Experiment 4 participants identified where a panel had been deleted from a comic strip and rated that strip's coherence. Overall, categories had consistent distributional tendencies within experiments and complementary tendencies across experiments. These results point toward an interaction between categorical roles and a global narrative structure. (shrink)

Autonomous vehicles (AVs) hold considerable promise for maintaining aging adults’ mobility as they develop impairments in driving skill. Nonetheless, attitudes can be a significant barrier to adoption as has been shown for other technologies. We investigated how different introductions to AV, video with a driver in the front seat, the rear seat, and a written description, affected attitudes, as well as how individual difference variables such as age, gender, prior knowledge, and personality traits predict attitudes within a middle-aged (Median age (...) = 34, IQR = 20, n = 441) Amazon Mechanical Turk sample. The 16-item attitude survey uncovered three factors: Concern with AV, Eagerness to Adopt AV technology, and Willingness to Relinquish Driving Control. ANOVAs showed that only age (younger less concerned) and gender, (females more concerned) were significant factors in Concern with AV. Only gender affected Willingness to Relinquish Driving Control, with males more willing. Multiple regressions that included previous knowledge level and personality traits showed a different pattern. Female gender and greater conscientiousness were associated with greater Concern about AV. Prior knowledge of AV was associated with less concern. Emotional stability and openness to experience were positive predictors of Eagerness to Adopt AV, whereas conscientiousness was a negative predictor. Prior knowledge and openness to experience, positively, and extraversion, negatively, were associated wi... (shrink)

In “The Evolutionary Debunking of Quasi-Realism,” Neil Sinclair and James Chamberlain present a novel answer that quasi-realists can pro-vide to a version of the reliability challenge in ethics—which asks for an explanation of why our moral beliefs are generally true—and in so doing, they examine whether evolutionary arguments can debunk quasi-realism. Although reliability challenges differ from EDAs in several respects, there may well be a connection between them. For the explanatory premise of an EDA may state that a particular (...) theory of beliefs of a certain kind does not, or cannot, provide a plausible account of why those beliefs might be generally true, and its epistemic premise may state that, if that is the case, then the beliefs in question have a negative epistemic status or the theory is false inasmuch as, if it were true, it would lead to those beliefs having such a negative epistemic status. The quasi-realist can answer the reli-ability challenge by claiming that, when we form our moral beliefs through a process of well-informed impartial reflection, we form them in response to the non-moral features of things on which depend the moral features they have. Hence, when we form beliefs by means of such a process, we are most likely forming true moral beliefs. (shrink)

RÉSUMÉ: Jaegwon Kim a montré de façon convaincante que les versions habituelles de la survenance décrivent en fait de simples relations de covariance et laissent échapper l’idée de dépendance. Mais puisque la dépendance du mental à l’endroit du physique est requise même par la version la plus faible du physicalisme, il semblerait bien que les notions actuelles de survenance n’accomplissent pas ce qu’on attendait d’elles. Je soutiens qu’en concevant la survenance dans une optique davidsonienne, comme une relation entre prédicats plutôt (...) qu’entre propriétés, on évite les inconvénients des versions plus familières, et que l’on donne prise, de la sorte, à un usage physicaliste de la survenance.

In their recent article “A Gentle Ethical Defence of Homeopathy,” Levy, Gadd, Kerridge, and Komesaroff use the claim that “lack of evidence is not equivalent to evidence of lack” as a component of their ethical defence of homeopathy. In response, this article argues that they cannot use this claim to shore up their ethical arguments. This is because it is false.

This unique textbook surveys the politics of the environment, providing a comprehensive and comparative introduction to ideas, activism and policy. Part One explores environmental philosophy and green political thought, assessing the relationship between 'green ideas' and other political doctrines. Part Two considers parties and movements, including the development of green parties from protest parties, the response of established political parties (...) to the environmental challenge, and the evolution of the environmental movement. Part Three analyses public policy-making and environmental issues at the international, national and local levels. As well as considering a wide variety of examples from around the world, this important new textbook includes glossary, lists of key issues, chapter summaries and guides to further study. (shrink)

Yujin Nagasawa has recently defended Frank Jackson’s knowledge argument from the “inconsistency objection.” The objection claims that the premises of the knowledge argument are inconsistent with qualia epiphenomenalism. Nagasawa defends Jackson by showing that the objection mistakenly assumes a causal theory of phenomenal knowledge. I argue that although this defense might succeed against two versions of the inconsistency objection, mine is unaffected by Nagasawa’s argument, in which case the inconsistency in the knowledge argument remains.

The aim of the paper is to give an ontologically informed account of disease that can aid in the construction of disease ontologies. The paper begins by distinguishing cases of diseases from what are purely structural abnormalities, referred to as ‘disorders’. The paper then presents a causal model apt for the understanding of disease that distinguishes diseases from both their causes and their potential effects. The analysis of disease defended treats disease in terms of distortions of standard cellular network processes, (...) where those distortions are incapable of self remedy and produce biologically disadvantageous symptoms.
