PurposeWe conducted a driving simulator study to investigate the effects of monitoring intersection cross traffic on gaze behaviors and responses to pedestrians by drivers with hemianopic field loss.MethodsSixteen HFL and sixteen normal vision participants completed two drives in an urban environment. At 30 intersections, a pedestrian ran across the road when the participant entered the intersection, requiring a braking response to avoid a collision. Intersections with these pedestrian events had either no cross traffic, one approaching car from the side opposite (...) the pedestrian location, or two approaching cars, one from each side at the same time.ResultsOverall, HFL drivers made more of cross-traffic on both the blind and seeing sides. They made more numerous and larger gaze scans when they fixated cars on both sides and had lower rates of unsafe responses to blind- but not seeing-side pedestrians. They were more likely to demonstrate compensatory blind-side fixation behaviors when there was no car on the seeing side. Fixation behaviors and unsafe response rates were most similar to those of NV drivers when cars were fixated on both sides.ConclusionFor HFL participants, making more scans, larger scans and safer responses to pedestrians crossing from the blind side were associated with looking at cross traffic from both directions. Thus, cross traffic might serve as a reminder to scan and provide a reference point to guide blind-side scanning of drivers with HFL. Proactively checking for cross-traffic cars from both sides could be an important safety practice for drivers with HFL. (shrink)

It is widely believed that Hume often wrote carelessly and contradicted himself, and that no unified, sound philosophy emerges from his writings. Don Garrett demonstrates that such criticisms of Hume are without basis. Offering fresh and trenchant solutions to longstanding problems in Hume studies, Garrett's penetrating analysis also makes clear the continuing relevance of Hume's philosophy.

If the quasi-realist wants to earn the right to talk like a moral realist, he needs to be able to make sense of moral error. A special form of error—fundamental moral error—is often thought to be u...

This paper extends an ongoing discussion about establishing a sharper way to conduct ethical investigations into managerial virtue. It does so by relying on Alasdair MacIntyre's moral philosophy in place of those more dominant approaches taken by scholars who make up the field of positive social science. A connection is drawn herein between a MacIntyrean “narrative approach” to investigating managerial virtue and the idea of “work as a calling.” Specifically, it will be argued that the MacIntyrean‐influenced idea of “work as (...) a calling” provides a substantive moral vision that supports an understanding of how virtuous managers ought to narrate their primary workplace motivations. Ultimately, virtuous managers fulfill a “political calling” to support and sustain (a) good work, (b) the good of individual lives, and (c) the common good of communities that their organization reaches. To do this, they must rely on the “shepherd virtue” of practical wisdom (phronesis). Practical wisdom aids virtuous managers’ thinking about achieving the ends of their “calling” as well as any necessary course‐corrections that ought to be made toward the better achievement of those good and worthy ends.

Given that there is a forceful case for thinking that the affluent are morally required to devote a substantial proportion of what they have to helping the poor, Garrett Cullity examines, refines and defends an argument of this form. He then identifies its limits.

We present a self-organizing approach to sentence processing that sheds new light on notional plurality effects in agreement attraction, using pseudopartitive subject noun phrases. We first show that notional plurality ratings predict verb agreement choices in pseudopartitives, in line with the “Marking” component of the Marking and Morphing theory of agreement processing. However, no account to date has derived notional plurality values from independently needed principles of language processing. We argue on the basis of new experimental evidence and a dynamical (...) systems model that the theoretical black box of notional plurality can be unpacked into objectively measurable semantic features. With these semantic features driving structure formation, our model reproduces the human verb production patterns as a byproduct of normal processing. Finally, we discuss how the self-organizing approach might be extended to other agreement attraction phenomena. (shrink)

This research examines the practice of cryonics and provides empirical evidence for an improved understanding of the motivations and attitudes of participants. Cryonics is the freezing of a person who has died of a disease in hopes of restoring life at some future time when a cure may be available. So far, about 300 people have been cryopreserved, and an additional 1200 have enrolled in such programs. The current work has three vectors. First, the results of a worldwide cryonics survey (...) carried out as part of this research are discussed. Second, a theoretical model is developed from the survey results to propose a Theory of Cryonic Life Extension which explains an individual’s decision to select cryopreservation. Third, the most distinctive survey result, a conceptualization of personal identity malleability, is extended with a philosophical formulation. Personal identity is found to be emergent, not fundamental, and thus may continue to evolve in concept and application, particularly in the longer time frames implicated by cryonics. The potential consequences of this work are that the conceptual norms materializing in the cryonics community could be forerunners of wider societal trends of how humans understand themselves as subjects in an era increasingly configured by science and technology.

Weak particularism about reasons is the view that the normative valency of some descriptive considerations varies, while others have an invariant normative valency. A defence of this view needs to respond to arguments that a consideration cannot count in favour of any action unless it counts in favour of every action. But it cannot resort to a global holism about reasons, if it claims that there are some examples of invariant valency. This paper argues for weak particularism, and presents a (...) framework for understanding the relationships between practical reasons. A central part of this framework is the idea that there is an important kind of reason-a 'presumptive reason'-which need not be conclusive, but which is neither pro tanto nor prima facie. /// [Richard Holton] Should particularists about ethics claim that moral principles are never true? Or should they rather claim that any finite set of principles will not be sufficient to capture ethics? This paper explores and defends the possibility of embracing the second of these claims whilst rejecting the first, a position termed 'principled particularism'. The main argument that particularists present for their position-the argument that holds that any moral conclusion can be superseded by further considerations-is quite compatible with principled particularism; indeed, it is compatible with the idea that every true moral conclusion can be shown to follow deductively from a finite set of premises. Whilst it is true that these premises must contain implicit ceteris paribus clauses, this does not render the arguments trivial. On the contrary, they can do important work in justifying moral conclusions. Finally the approach is briefly applied to the related field of jurisprudence. (shrink)

This book explores the contemporary crisis of biblical interpretation by examining modern and postmodern forms of the 'hermeneutics of suspicion'. Garrett Green looks at several thinkers who played key roles in creating a radically suspicious reading of the Bible. After Kant, Hamann and Feuerbach comes Nietzsche, who marked the turn from modern to postmodern suspicion. Green argues that similarities between Derrida's deconstruction and Barth's theology of signs show that postmodern suspicion ought not to be viewed simply as a threat (...) to theology but as a secular counterpart to its own hermeneutical insights. When theology attends to its proper task of describing the grammar of scriptural imagination, it discovers a source of suspicion more radical than the secular, the hermeneutical expression of God's gracious judgement. Green concludes that Christians are committed to the hermeneutical imperative, the never-ending struggle for the meaning of scripture in the hopeful insecurity of the faithful imagination. (shrink)

Among theories of human language comprehension, cue‐based memory retrieval has proven to be a useful framework for understanding when and how processing difficulty arises in the resolution of long‐distance dependencies. Most previous work in this area has assumed that very general retrieval cues like [+subject] or [+singular] do the work of identifying (and sometimes misidentifying) a retrieval target in order to establish a dependency between words. However, recent work suggests that general, handpicked retrieval cues like these may not be enough (...) to explain illusions of plausibility (Cunnings & Sturt, 2018), which can arise in sentences like The letter next to the porcelain plate shattered. Capturing such retrieval interference effects requires lexically specific features and retrieval cues, but handpicking the features is hard to do in a principled way and greatly increases modeler degrees of freedom. To remedy this, we use well‐established word embedding methods for creating distributed lexical feature representations that encode information relevant for retrieval using distributed retrieval cue vectors. We show that the similarity between the feature and cue vectors (a measure of plausibility) predicts total reading times in Cunnings and Sturt’s eye‐tracking data. The features can easily be plugged into existing parsing models (including cue‐based retrieval and self‐organized parsing), putting very different models on more equal footing and facilitating future quantitative comparisons.

We’ve seen a significant increase in the attention AI research is receiving this past decade, in large part due to some of the impressive feats of machine learning, particularly deep learning. This has resulted in something of a hype in the ability of AI’s in tackling various issues. The aim of the current essay is to examine the speculative questions “what would it mean for systems to transition from merely intelligently executing a task to knowledgably executing a task?” and “what (...) is the relation between consciousness and intelligence, such that specific evaluations about conscious AI might be made?” We offer what we hope is a roadmap for how to navigate asking these questions and a route forward in understanding how AI goes from intelligence to knowledge and potentially to some types of consciousness.

As a first step in involving user emotion in human‐computer interaction, a memory‐based expert system (JANUS; Kearney, 1991) was designed to interpret facial expression in terms of the signaled emotion. Anticipating that a VDU‐mounted camera will eventually supply face parameters automatically, JANUS now accepts manually made measurements on a digitized full‐face photograph and returns emotion labels used by college students. An intermediate representation in terms of face actions (e.g., mouth open) is also used. Production rules convert the geometry into these. (...) A dynamic memory (Kolodner, 1984; Schank, 1982) interprets the face actions in terms of emotion labels. The memory is dynamic in the sense that new emotion labels can be learned with experience. A prototype system has been implemented on a Sun 2/120 system using POPLOG. Validation studies on the prototype suggest that the interpretations achieved are generally consistent with those of college students without formal instruction in emotion signals. (shrink)

Beginning with an overview of Hume's life and work, Don Garrett introduces in clear and accessible style the central aspects of Hume's thought. These include Hume's lifelong exploration of the human mind; his theories of inductive inference and causation; skepticism and personal identity; moral and political philosophy; aesthetics; and philosophy of religion. The final chapter considers the influence and legacy of Hume's thought today. Throughout, Garrett draws on and explains many of Hume's central works, including his Treatise of (...) Human Nature , Enquiries Concerning Human Understanding , and Dialogues Concerning Natural Religion . Hume is essential reading not only for students of philosophy, but anyone in the humanities and social sciences and beyond seeking an introduction to Hume's thought. (shrink)

At the end of a thoughtful article on the future of nuclear war, Wiesner and York concluded that: "Both sides in the arms race are... confronted by the dilemma of steadily increasing military power and steadily decreasing national security. It is our considered professional judgment that this dilemma has no technical solution. If the great powers continue to look for solutions in the area of science and technology only, the result will be to worsen the situation.".

Three things often recognized as central to morality are concern for others’ welfare, respect for their self-expression, and cooperation in worthwhile collective activity. When philosophers have proposed theories of the substance of morality, they have typically looked to one of these three sources to provide a single, fundamental principle of morality – or they have tried to formulate a master-principle for morality that combines these three ideas in some way. This book views them instead as three independently important foundations of (...) morality. It sets out a plural-foundation moral theory with affinities to that of W.D. Ross. There are major differences: the account of the foundations of morality differs from Ross’s, and there is a more elaborate explanation of how the rest of morality derives from them. However, the overall aim is similar. This is to illuminate the structure of morality by showing how its complex content is generated from a relatively simple set of underlying elements – with the complexity resulting from the various ways in which one part of morality can derive from another, and the various ways in which they can interact. Plural-foundation moral theories are sometimes criticized for having nothing helpful to say about cases in which their fundamental norms conflict. Responding to this, the book concludes with three detailed applications of the theory: to the questions surrounding paternalism, the use of others as means, and our moral responsibilities as consumers.

The past six decades have seen rising interest in the philosophy of time, driven in large measure by the metaphysical implications of the physical theories of relativity and quantum mechanics. Philosophical theology has only recently begun serious interaction with contemporary metaphysics of time. In particular, the issue of God's temporal mode of being has come under investigation In Part 1, I begin with the metaphysics of time, explicating and defending a causal account of dynamic time. I then consider objections that (...) can be brought against this account from the standpoint of the Special and General Theories of Relativity and Quantum Mechanics, and conclude that one of the objections are compelling. In Part II, I consider the evidence from Scripture relative to God's temporal mode of being, and find that it is neutral between a temporal and an atemporal conception. The arguments upholding the medieval consensus in philosophical theology of divine timelessness are evaluated, along with contemporary arguments for atemporality. Openness to divine temporality is discernible in some medieval philosophers; their arguments, along with contemporary arguments for temporality, are investigated. I then offer an analysis of the concept of omnitemporality which I take to be the form of temporality most appropriate to expressing God's temporal mode of being. Finally I argue that objections to omnitemporality are not forceful, and that the concept has in its favor greater explanatory power for a range of issues in philosophical theology. (shrink)

Considering the mutual benefits of blockchain and transhumanism, this essay proposes crypto cloudminds as a safe mechanism by which the human mind might transcend its unitary limitations by permissioning partial resources to join a multi-party mind in a cloud-based environment. Cloudminds could have diverse purposes including problem solving, learning, experience, exploration, innovation, artistic expression, and other personal development activities. Crypto cloudminds could be multicurrency, operating with payment remuneration, security, and ideas as the denominations of measure. For thriving in the future, (...) mind node peers could enter “Yes-and” Payment Channels with one another for collaborative idea development. For surviving in the future, good-player behavior could be game-theoretically enforced with the simultaneous privacy-transparency property of blockchains, together with the immutable peer-confirmed consensus algorithm and audit-log checks and balances system. Overall, blockchains might serve as an institutional technology that is the basis for treaties and progress in a multi-species society of human, algorithm, and machine, guiding the way to positive transhuman futures.

How should we think of the relationship between the climate harms that people will suffer in the future and our current emissions activity? Who does the harming, and what are the moral implications? One way to address these questions appeals to facts about the expected harm associated with one’s own individual energy-consuming activity, and argues that it is morally wrong not to offset one’s own personal carbon emissions. The first half of the article questions the strength of this argument. The (...) second half maintains that a different kind of argument for the same conclusion is stronger. This focuses on the harms that are attributable to carbon emitters considered collectively. (shrink)

This paper presents a moral philosophical account of free riding, specifying the conditions under which failing to pay for nonrival goods is unfair. These conditions do not include the voluntary acceptance of the goods: this controversial claim is supported on the strength of a characterization of the kind of unfairness displayed in paradigm cases of free riding. Thus a "Principle of Fairness" can potentially serve as a foundation for political obligations. The paper also discusses the relation between its moral philosophical (...) account of free riding, and a game theoretic or economic account. (shrink)

The strong continuity thesis postulates that the properties of mind are an enriched version of the properties of life, and thus that life and mind differ in degree and not kind. A philosophical problem for this view is the ostensive discontinuity between humans and other animals in virtue of our use of symbols—particularly the presumption that the symbolic nature of human cognition bears no relation to the basic properties of life. In this paper, we make the case that a genuine (...) account of strong continuity requires the identification of some sort of correlate of symbol-use in basic life properties. Our strategy is three-fold: 1) we argue that examples of proto-symbolism in simple living systems would be consistent with an evolutionary trajectory that ultimately produced symbolic cognition in humans; 2) we introduce Gordon Tomkins’ biological notion of ‘symbol’ as something that represents to the organism a feature of its environment that is significant to its survival; and 3) we employ this biological understanding of symbol-use to suggest that the symbolic nature of human cognition can be understood as an enriched version of the basic symbolic properties of life, thus preserving life-mind continuity in this context.

In this paper we address the interrelated questions of why and how certain features of an organism’s environment become meaningful to it. We make the case that knowing the biology is essential to understanding the foundation of meaning-making in organisms. We employ Miguel Nicolelis et al’s seminal research on the mammalian somatosensory system to enrich our own concept of brain-objects as the neurobiological intermediary between the environment and the consequent organismic behavior. In the final section, we explain how brain-objects advance (...) the ongoing discussion of what constitutes a biosemiotic system. In general, this paper acknowledges Marcello Barbieri’s call for biology to make room for meaning, and makes a contribution to that end. (shrink)

And many of us find it hard to see how the remoteness of needy people, either physical, social or psychological, should make a difference to this. Maybe it makes a difference to how wrong it is not to help, but it is hard to see how it can make a difference to whether not helping is (...) wrong. (shrink)

The purpose of this article is to respond to Jacques Derrida’s reading of Immanuel Kant’s laws of hospitality and to offer a deeper exploration into Kant’s separation of a cosmopolitan right to visit ( Besuchsrecht) and the idea of a universal right to reside ( Gastrecht). Through this discussion, the various laws of hospitality will be examined, extrapolated and outlined, particularly in response to the tensions articulated by Derrida. By doing so, this article will offer a reinterpretation of the laws (...) of hospitality, arguing that hospitality is not meant to capture all the conditions necessary for cosmopolitan citizenship or for a thoroughgoing condition of cosmopolitan justice as Derrida assumes. This is because hospitality could be understood as the basic normative requirement necessary to establish an ethical condition for intersubjective communication at the global level, where discursive communication regarding the substance of a future condition of cosmopolitan justice is to be subjected to global public reason.

The pandemic creates unprecedented challenges to society and to health care systems around the world. Like all crises, these provide a unique opportunity to rethink the fundamental limiting assumptions and institutional inertia of our established systems. These inertial assumptions have obscured deeply rooted problems in health care and deflected attempts to address them. As hospitals begin to welcome all patients back, they should resist the temptation to go back to business as usual. Instead, they should retain the more deliberative, explicit, (...) and transparent ways of thinking that have informed the development of crisis standards of care. The key lesson to be learned from those exercises in rational deliberation is that justice must be the ethical foundation of all standards of care. Justice demands that hospitals take a safety‐net approach to providing services that prioritizes the most vulnerable segments of society, continue to expand telemedicine in ways that improve access without exacerbating disparities, invest in community‐based care, and fully staff hospitals and clinics on nights and weekends.

This paper argues that it is morally wrong for the affluent not to contribute money or time to famine relief. It begins by endorsing an important methodological line of objection against the most prominent philosophical advocate of this claim, Peter Singer. This objection attacks his strategy of invoking a principle the acceptability of which is apparently based upon its conformity with "intuitive" moral judgements in order to defend a strongly counterintuitive conclusion. However, what follows is an argument for that counterintuitive (...) conclusion which claims to circumvent the methodological objection, and moreover without having to resort to a justificational ethical theory. How can this be done? Merely by appealing, it is maintained, to the simple practical considerations which are characteristic of the virtues of kindness and justice. Accordingly, an account of those virtues, outlining the structure of the practical reasoning of their possessors, occupies a central place in the argument. The paper displays the resources for normative argument of a "virtue ethics;" but it claims also that its conclusion cannot be escaped by the adherents of any plausible moral outlook. And this yields a further conclusion. All moral outlooks, and not only those which equate the moral point of view with the impartial point of view, face a "problem of demandingness" - for it seems to be a corollary of the argument that if one is to be living a life which is not immoral, one is precluded from pursuing practically any source of personal satisfaction.

This article introduces the symposium “Toward a Philosophy of Blockchain,” which provides a philosophical contemplation of blockchain technology, the digital ledger software underlying cryptocurrencies such as bitcoin, for the secure transfer of money, assets, and information via the Internet without needing a third-party intermediary. The symposium offers philosophical scholarship on a new topic, blockchain technology, from a variety of perspectives. The philosophical themes discussed include mathematical models of reality, signification, and the sociopolitical institutions that structure human life and interaction. The (...) symposium also investigates the metaphilosophical theme of how to create a philosophy of anything, specifically a new topic such as blockchain technology. Repeated themes are identified, in all areas of philosophical inquiry, and conceptual resources are elaborated to contribute to a philosophical understanding of blockchain technology. Thus, philosophy as a metaphilosophical approach is shown to be able to provide an understanding of the conceptual, theoretical, and foundational dimensions of novelty and emergence in the world, with a particular focus on blockchain technology.

We have an argument for rejecting an iterative but not an aggregative approach to the life-saving analogy. This means that, while Chs 7–9 show that certain forms of personal spending are morally defensible, the life-saving analogy still supplies us with grounds for thinking that other forms of personal spending are not. Some of the main practical implications of the resulting view are spelled out. The resulting view is not puritanical, but is still demanding in the constraints it places on living (...) a morally good life. (shrink)
