Sloman suggests that although many try to model consciousness as a unitary and abstract entity, the project is an incoherent one. This claim will be supported, but it will also be argued that current movements in consciousness research are broadly consistent with Sloman's "alternative" suggestions of how best to make progress in this area.

Block [Block, N. . Two neural correlates of consciousness. Trends in Cognitive Science, 9, 46–52] and Snodgrass claim that a signal detection theory analysis of qualitative difference paradigms, in particular the exclusion failure paradigm, reveals cases of phenomenal consciousness without access consciousness. This claim is unwarranted on several grounds. First, partial cognitive access rather than a total lack of cognitive access can account for exclusion failure results. Second, Snodgrass’s Objective Threshold/Strategic model of perception relies on a problematic ‘enable’ approach to (...) perception that denies the possibility of intentional control of unconscious perception and any effect of following different task instructions on the presence/absence of phenomenal consciousness. Many of Block’s purported examples of phenomenal consciousness without cognitive access also rely on this problematic approach. Third, qualitative difference paradigms may index only a subset of access consciousness. Thus, qualitative difference paradigms like exclusion failure cannot be used to isolate phenomenal consciousness, any attempt to do so still faces serious methodological problems. (shrink)

The source of endless speculation and public curiosity, our scientific quest for the origins of human consciousness has expanded along with the technical capabilities of science itself and remains one of the key topics able to fire public as much as academic interest. Yet many problematic issues, identified in this important new book, remain unresolved. Focusing on a series of methodological difficulties swirling around consciousness research, the contributors to this volume suggest that ‘consciousness’ is, in fact, not a wholly viable (...) scientific concept. Supporting this ‘eliminativist‘ stance are assessments of the current theories and methods of consciousness science in their own terms, as well as applications of good scientific practice criteria from the philosophy of science. For example, the work identifies the central problem of the misuse of qualitative difference and dissociation paradigms, often deployed to identify measures of consciousness. It also examines the difficulties that attend the wide range of experimental protocols used to operationalise consciousness—and the implications this has on the findings of integrative approaches across behavioural and neurophysiological research. The work also explores the significant mismatch between the common intuitions about the content of consciousness, that motivate much of the current science, and the actual properties of the neural processes underlying sensory and cognitive phenomena. Even as it makes the negative eliminativist case, the strong empirical grounding in this volume also allows positive characterisations to be made about the products of the current science of consciousness, facilitating a re-identification of target phenomena and valid research questions for the mind sciences.​.

Introspective and phenomenological methods are once again being used to support the use of subjective reports, rather than objective behavioural measures, to investigate and measure consciousness. Objective measures are often seen as useful ways of investigating the range of capacities subjects have in responding to phenomena, but are fraught with the interpretive problems of how to link behavioural capacities with consciousness. Instead, gathering subjective reports is seen as a more direct way of assessing the contents of consciousness. This article explores (...) three different ways of gathering subjective reports that have been discussed in recent literature on consciousness, including immediate retrospection (Schwitzgebel [2007]) and two types of introspective training (Overgaard et al. [2004]; Schwitzgebel [2008]). Although not an exhaustive survey of the range of introspective methods now used, the discussion below highlights a range of general methodological problems with introspective methods, many identified up to a century ago. It is argued that none of the methodological problems established in earlier criticisms of the use of subjective reports have been dealt with, yet are still valid criticisms. Given that this is not the first time proponents of introspective, subjective measures of conscious have failed to answer these criticisms, this raises the question of whether the goal of providing a measure of consciousness is a methodological muddle worth pursuing.

This paper argues for a position of ‘dark pessimism’ towards introspective reports playing a strong justificatory role in consciousness science, based on the application of frameworks and concepts of measurement. I first show that treating introspective reports as measurements fits well within current discussions of the reliability of introspection, and argue that introspective reports must satisfy at least a minimal definition of measurement in order to play a justificatory role in consciousness science. I then show how treating introspective reports as (...) measurements makes it possible to identify the foundational methodological problems that underlie much of the current philosophical and scientific debate about the status of introspective evidence in studying consciousness. I argue that these problems prevent introspective reports from playing a strong justificatory role and resolving long-standing debates in consciousness science, both in contemporary work and in the future.

Snodgrass et al.’s commentary makes explicit one of the major problems in consciousness research; that there seem to be just as many definitions of basic terms are there are people in the field. Although Snodgrass et al.’s position appears at odds with the views expressed in Irvine , many of their arguments are actually consistent with the proposed views, or else fail to engage with them as a consequence of the shifting goal posts of what basic terms mean.

Consciousness is now a hot topic in both philosophy and the cognitive sciences, yet there is much controversy over how to measure it. First, it is not clear whether biased subjective reports should be taken as adequate for measuring consciousness, or if more objective measures are required. Ways to benefit from the advantages of both these measures in the form of ‘Type 2’ metacognitive measures are under development, but face criticism. Research into neurophysiological measures of consciousness is potentially very valuable, (...) but often hindered by its dependence on behavioural measures that are themselves controversial. Newer informational measures are theoretically interesting, but as yet not easily applicable, while other measures of consciousness are designed for application in clinical cases . Although much optimism accompanies research into measures of consciousness, the controversies and methodological problems reviewed here suggest that making progress in this area may be more difficult than is often acknowledged.

Studies on American poetry by ten contributors. Notes at the end of each chapter.

The Hard Problem is surrounded by a vast literature, to which it is increasingly hard to contribute to in any meaningful way. Accordingly, the strategy here is not to offer any new metaphysical or ‘in principle’ arguments in favour of the success of materialism, but to assume a Type Q(uinian) approach and look to contemporary consciousness science to see how the concept of consciousness fares there, and what kind of explanations we can hope to offer of it. It is suggested (...) that while they will be materialist explanations, they will not be of the form that many scientists and philosophers would have us believe, but instead prompt a very different set of expectations and research projects.

This paper is aimed at identifying how a model’s explanatory power is constructed and identified, particularly in the practice of template-based modeling (Humphreys, Philos Sci 69:1–11, 2002; Extending ourselves: computational science, empiricism, and scientific method, 2004), and what kinds of explanations models constructed in this way can provide. In particular, this paper offers an account of non-causal structural explanation that forms an alternative to causal–mechanical accounts of model explanation that are currently popular in philosophy of biology and cognitive science. Clearly, (...) defences of non-causal explanation are far from new (e.g. Batterman, Br J Philos Sci 53:21–38, 2002a; The devil in the details: asymptotic reasoning in explanation, reduction, and emergence, 2002b; Pincock, Noûs 41:253–275, 2007; Mathematics and scientific representation 2012; Rice, Noûs. doi:10.1111/nous.12042, 2013; Biol Philos 27:685–703, 2012), so the targets here are focused on a particular type of robust phenomenon and how strong invariance to interventions can block a range of causal explanations. By focusing on a common form of model construction, the paper also ties functional or computational style explanations found in cognitive science and biology more firmly with explanatory practices across model-based science in general.

Identifying which nonhuman animal species are capable of feeling pain is important both for understanding pain mechanisms more generally and for informing animal welfare regulations, particularly in genera that are not yet widely protected. A common way to try to provide evidence of pain experiences is through behavioral indicators. In this paper I use a very simple interventionist approach to experimentation, and the contrast case provided by C. elegans, to argue that behavioral indicators commonly used for identifying pain in nonhuman (...) animals are much less robust than typically presented. Indeed, I argue that many behavioral indicators of pain are invalid as they are currently described. More positively, this analysis makes it possible to identify what valid criteria might look like, and where relevant, to identify existing evidence related to them. Based on this I propose that the best way to make progress on questions around animal pain is to clearly ally them with questions about animal consciousness more generally, and to productively use conceptual and empirical work in both areas to develop more theoretically defensible behavioral indicators.

Weisberg (2006) and Godfrey-Smith (2006, 2009) distinguish between two forms of theorising: data-driven ‘abstract direct representation’ and modeling. The key difference is that when using a data-driven approach, theories are intended to represent specific phenomena, so directly represent them, while models may not be intended to represent anything, so represent targets indirectly, if at all. The aim here is to compare and analyse these practices, in order to outline an account of model-based theorising that involves direct representational relationships. This is (...) based on the way that computational templates Humphreys (2002, 2004) are now used in cognitive neuroscience, and draws on the dynamic and tentative process of any kind of theory construction, and the idea of partial, purpose-relative representation.

The aim of this article is to mount a challenge to gesture-first hypotheses about the evolution of language by identifying constraints on the emergence of symbol use. Current debates focus on a range of pre-conditions for the emergence of language, including co-operation and related mentalising capacities, imitation and tool use, episodic memory, and vocal physiology, but little specifically on the ability to learn and understand symbols. It is argued here that such a focus raises new questions about the plausibility of (...) gesture-first hypotheses, and so about the evolution of language in general. After a brief review of the methodology used in the article, it is argued that existing uses of gesture in hominid communities may have prohibited the emergence of symbol use, rather than ‘bootstrapped’ symbolic capacities as is usually assumed, and that the vocal channel offers other advantages in both learning and using language. In this case, the vocal channel offers a more promising platform for the evolution of language than is often assumed. (shrink)

The target paper (building on Ginsburg and Jablonka in JTB 381:55–60, 2015, The evolution of the sensitive soul: Learning and the origins of consciousness, MIT Press, USA, 2019) makes a significant and novel claim: that positive cases of non-human consciousness can be identified via the capacity of unlimited associative learning (UAL). In turn, this claim is generated by a novel methodology, which is that of identifying an evolutionary ‘transition marker’, which is claimed to have theoretical and empirical advantages over other (...) approaches. In this commentary I argue that UAL does not function as a successful transition marker (as defined by the authors), and has internal problems of its own. However, I conclude that it is still a very productive anchor for new research on the evolution of consciousness. (shrink)

One of the possible ways to explain the experience of visual richness is to posit a level of nonconceptual or phenomenal experience. The contents of this level of experience have recently been equated with the contents of sensory memory. It will be argued that sensory memory cannot provide these contents along two broad points. First, the conception of sensory memory relied on by these authors conflates the phenomena of visible and informational persistence, and makes use of an outdated “iconic” model (...) of visual short-term memory. Second, the way in which subjects’ reports are used to show that specific unreported contents are nevertheless experienced on a phenomenal level is questioned, using evidence on gist and high-level categorical perceptual processing. It is concluded that sensory memory, properly understood, cannot provide the kind of visual content required to support a level of richly detailed phenomenal experience, or a pictorial account of perception. Finally, alternative ways of explaining visual richness are suggested. (shrink)

While the search for scientific measures, models and explanations of consciousness is currently a growing area of research, this thesis identifies a series of methodological problems with the field that suggest that ‘consciousness’ is not in fact a viable scientific concept. This eliminativist stance is supported by assessing the current theories and methods of consciousness science on their own grounds, and by applying frameworks and criteria for ‘good’ scientific practice from philosophy of science. A central problem consists in the way (...) that qualitative difference and dissociation paradigms are misused in order to identify measures of consciousness. Another problem concerns the wide range of experimental protocols used to operationalise consciousness and the implications this has on the findings of integrative approaches across behavioural and neurophysiological research. Following from this the way that mechanisms of consciousness have been inadequately demarcated, and how this affects whether ‘consciousness’ refers to any scientific kinds, is discussed. A final problem is the significant mismatch that exists between the common intuitions and phenomenological claims about the content of consciousness that motivate much current consciousness science, and the properties of neural processes that underlie sensory and cognitive phenomena.It is argued that the failure of these methods to be appropriately applied to the concept of consciousness, both in particular cases, and in the way that these methods fail to fulfil their crucial heuristic role in the practise of science, suggests that the concept of ‘consciousness’ should be eliminated from scientific discourse. Aside from the purely negative claim found in eliminativist accounts, the strong empirical grounding of this eliminativist claim also allows positive characterisations to be made about the products of the current science of consciousness, to (re-)identify real target phenomena and valid research questions for the mind sciences, and to suggest how the intuitions that ground the confused research program on consciousness result from real features of our cognitive architecture.

The Many Faces of Patriotism debate the consequences of the 21st century's patriotic resurgence, examining it both in theoretical and comparative terms that draw on examples of patriotism from ancient Greece to post-apartheid South Africa.

Insults are part of the fabric of daily life. But why do we insult each other? Why do insults cause us such pain? Can we do anything to prevent or lessen this pain? Most importantly, how can we overcome our inclination to insult others? In A Slap in the Face, William Irvine undertakes a wide-ranging investigation of insults, their history, the role they play in social relationships, and the science behind them. He examines not just memorable zingers, such as (...) Elizabeth Bowen's description of Aldous Huxley as "The stupid person's idea of a clever person," but subtle insults as well, such as when someone insults us by reporting the insulting things others have said about us: "I never read bad reviews about myself," wrote entertainer Oscar Levant, "because my best friends invariably tell me about them." Irvine also considers the role insults play in our society: they can be used to cement relations, as when a woman playfully teases her husband, or to enforce a social hierarchy, as when a boss publicly berates an employee. He goes on to investigate the many ways society has tried to deal with insults-by adopting codes of politeness, for example, and outlawing hate speech-but concludes that the best way to deal with insults is to immunize ourselves against them: We need to transform ourselves in the manner recommended by Stoic philosophers. We should, more precisely, become insult pacifists, trying hard not to insult others and laughing off their attempts to insult us.A rousing follow-up to A Guide to the Good Life, A Slap in the Face will interest anyone who's ever delivered an insult or felt the sting of one--in other words, everyone.

More than forty years have passed since Congress, in response to the Civil Rights Movement, enacted sweeping antidiscrimination laws in the Civil Rights Act of 1964, the Voting Rights Act of 1965, and the Fair Housing Act of 1968. As a signal achievement of that legacy, in 2008, Americans elected their first African American president. Some would argue that we have finally arrived at a postracial America, butThe Imperative of Integration indicates otherwise. Elizabeth Anderson demonstrates that, despite progress toward (...) racial equality, African Americans remain disadvantaged on virtually all measures of well-being. Segregation remains a key cause of these problems, and Anderson skillfully shows why racial integration is needed to address these issues. Weaving together extensive social science findings--in economics, sociology, and psychology--with political theory, this book provides a compelling argument for reviving the ideal of racial integration to overcome injustice and inequality, and to build a better democracy. -/- Considering the effects of segregation and integration across multiple social arenas, Anderson exposes the deficiencies of racial views on both the right and the left. She reveals the limitations of conservative explanations for black disadvantage in terms of cultural pathology within the black community and explains why color blindness is morally misguided. Multicultural celebrations of group differences are also not enough to solve our racial problems. Anderson provides a distinctive rationale for affirmative action as a tool for promoting integration, and explores how integration can be practiced beyond affirmative action. -/- Offering an expansive model for practicing political philosophy in close collaboration with the social sciences, this book is a trenchant examination of how racial integration can lead to a more robust and responsive democracy.

The theory of visual perception that Irvin Rock develops and supports in this book with numerous original experiments, views perception as the outcome of a process of unconscious inference, problem solving, and the building of structural descriptions of the external world.

A practical, refreshingly optimistic guide that uses centuries-old wisdom to help us better cope with the stresses of modern living. Some people bounce back in response to setbacks; others break. We often think that these responses are hardwired, but fortunately this is not the case. Stoicism offers us an alternative approach. Plumbing the wisdom of one of the most popular and successful schools of thought from ancient Rome, philosopher William B. Irvine teaches us to turn any challenge on its (...) head. The Stoic Challenge, then, is the ultimate guide to improving your quality of life through tactics developed by ancient Stoics, from Marcus Aurelius and Seneca to Epictetus. This book uniquely combines ancient Stoic insights with techniques discovered by contemporary psychological research, such as anchoring and framing. The result is a surprisingly simple strategy for dealing with life’s unpleasant and unexpected challenges—from minor setbacks like being caught in a traffic jam or having a flight cancelled to major setbacks like those experienced by physicist Stephen Hawking, who slowly lost the ability to move, and writer Jean-Dominique Bauby, who suffered from locked-in syndrome. The Stoics discovered that thinking of challenges as tests of character can dramatically alter our emotional response to them. Irvine’s updated “Stoic test strategy” teaches us how to transform life’s stumbling blocks into opportunities for becoming calmer, tougher, and more resilient. Not only can we overcome everyday obstacles—we can benefit from them, too. (shrink)

Feminist epistemology and philosophy of science studies the ways in which gender does and ought to influence our conceptions of knowledge, the knowing subject, and practices of inquiry and justification. It identifies ways in which dominant conceptions and practices of knowledge attribution, acquisition, and justification systematically disadvantage women and other subordinated groups, and strives to reform these conceptions and practices so that they serve the interests of these groups. Various practitioners of feminist epistemology and philosophy of science argue that dominant (...) knowledge practices disadvantage women by (1) excluding them from inquiry, (2) denying them epistemic authority, (3) denigrating their “feminine” cognitive styles and modes of knowledge, (4) producing theories of women that represent them as inferior, deviant, or significant only in the ways they serve male interests, (5) producing theories of social phenomena that render women's activities and interests, or gendered power relations, invisible, and (6) producing knowledge (science and technology) that is not useful for people in subordinate positions, or that reinforces gender and other social hierarchies. Feminist epistemologists trace these failures to flawed conceptions of knowledge, knowers, objectivity, and scientific methodology. They offer diverse accounts of how to overcome these failures. They also aim to (1) explain why the entry of women and feminist scholars into different academic disciplines, especially in biology and the social sciences, has generated new questions, theories, and methods, (2) show how gender has played a..

Irvine looks at various Stoic techniques for attaining tranquility and shows how to put these techniques to work in our own life.

We citizens of the 21st century live in a world where division of epistemic labour rules. Most of what we know we learned from the spoken or written word of others, and we depend in endless practical ways on the technological fruits of the dispersed knowledge of others—of which we often know almost nothing—in virtually every moment of our lives. Interest has been growing in recent years amongst philosophers, in the issues in epistemology raised by this fact. One issue concerns (...) the depth and extent of our epistemic dependence on testimony, as we may label this broad epistemic source: Do we have any knowledge at all that is free of epistemic dependence on what we have learned from others? A related question is whether our entitlement to believe what we have learned from others can be explained without invoking any epistemic principles special to testimony. These questions concern, as it were, the macro-epistemology of testimony. In the present discussion I shall focus instead on the micro foundations. Testimony, in our broad sense, can occur through an extensive range of types of spoken and written means of purportedly factual communication, including telephone calls, e-mails and personal letters, lectures and radio broadcasts, newspapers, textbooks and encyclopaedias, personal diaries, and public records of all kinds. But the central paradigm—what started the whole communication thing off—is surely that of face-to-face spoken encounter, when one person tells something to another, thereby intending and hoping to share her knowledge with her audience. I begin by describing the speech act of telling, identifying what takes place in a felicitous act of telling. From the nature of the speech act of telling, we see precisely how it is that knowledge is, when all goes as it should, acquired from teller by trusting hearer, in such an act, and in acts of testimony more broadly.

What attitude should philosophers take toward their favorite philosophical theories? I argue that the answer is belief and middling to low credence. I begin by discussing why disagreement has motivated the view that we cannot rationally believe our philosophical theories. Then, I show why considerations from disagreement actually better support my view. I provide two additional arguments for my view: the first concerns roles for belief and credence and the second explains why believing one’s philosophical theories is superior to accepting (...) them. I close by addressing objections, including implications my view has for the Lockean thesis, the view that there is a normative connection between belief and high credence. (shrink)

Traditional theistic arguments conclude that God exists. Pragmatic theistic arguments, by contrast, conclude that you ought to believe in God. The two most famous pragmatic theistic arguments are put forth by Blaise Pascal (1662) and William James (1896). Pragmatic arguments for theism can be summarized as follows: believing in God has significant benefits, and these benefits aren’t available for the unbeliever. Thus, you should believe in, or ‘wager on’, God. This article distinguishes between various kinds of theistic wagers, including finite (...) vs. infinite wagers, premortem vs. postmortem wagers, and doxastic vs. acceptance wagers. Then, we’ll turn to the epistemic-pragmatic distinction, and discusses the nuances of James’ argument, and how views like epistemic permissivism and epistemic consequentialism provide unique “hybrid” wagers. Finally, we’ll cover outstanding objections and responses. (shrink)

Recent defenses of same-sex marriage and polygamy have invoked the liberal doctrines of neutrality and public reason. Such reasoning is generally sound but does not go far enough. This paper traces the full implications of political liberalism for marriage. I argue that the constraints of public reason, applied to marriage law, entail ‘minimal marriage’, the most extensive set of state-determined restrictions on marriage compatible with political liberalism. Minimal marriage sets no principled restrictions on the sex or number of spouses and (...) the nature and purpose of their caring relationships, nor on which marital rights are exchanged, and whether they are exchanged reciprocally or asymmetrically. Minimal marriage supports adult care networks, urban tribes, friendships, and other forms of relationships as well as ‘traditional’ marriages. I provide a publically justifiable rationale for a legal framework supporting non-dependent caring relationships between adults. The argument is that caring relationships are primary goods, and that liberal justice accordingly requires legal frameworks supporting caring relationships. Minimal marriage is one such framework.

History was a continuous cycle driven by the gods. Societies began by being small, impoverished, and insignificant, then became great, then proud and decadent, and finally were overthrown by a different small, impoverished people, with the cycle beginning anew.

Herbert's themes about human action, fatalism versus free will, and the repetition of religious motifs across vast distances of space and time. Greek mythology and tragedy appear on (...) the very first page of Dune with the use of a single word: Atreides. Much like in the Dune series, History emerged in the ancient Greek world by combining mythology, epic narrative, and tragedy.

Many of us are tempted by the thought that the future is open, whereas the past is not. The future might unfold one way, or it might unfold another; but the past, having occurred, is now settled.

A new resolution of the mind-body problem that reconciles materialism and idealism.

On a rainy day in May 1988, a lowland gorilla named Willie B. stepped outdoors for the first time in twenty-seven years, into a new landscape immersion exhibit. Born in Africa, Willie B. had been captured by an animal collector and sold to a zoo. During the decades he spent in a cage, zoos stopped collecting animals from the wild and Americans changed the ways they wished to view animals in the zoo. Zoos developed new displays to simulate landscapes like (...) the Amazon River basin and African forests. Exhibits similar to animals' natural habitats began to replace old-fashioned animal houses. But such displays are only the most recent effort of zoos to present their audiences with an authentic experience of nature. Since the first zoological park opened in the United States in Philadelphia in 1874, zoos have promised their visitors a journey into the natural world. And for more than a century they have been popular places for education and recreation: every year more than 130 million Americans go to zoos to look at the animals and enjoy a day outdoors. The first book-length history of American zoos, Animal Attractions examines the meaning of nature in the city by looking at the ways zoos have assembled and displayed their animal collections. Situated literally and culturally in the American middle landscape, zoos are concrete expressions of longstanding tensions between wildness and civilization, science and popular culture, education and entertainment. In their efforts to promote nature appreciation, they reveal much about how our culture envisions the natural world and the human place in it and how these ideas have changed. (shrink)

Artificial intelligence (AI) will drastically change the healthcare system. Radiology is one speciality that is most affected as AI algorithms are increasingly used in diagnostic imaging. AI‐enhanced health technologies will, inter alia, increase workflow efficiency, improve diagnostic accuracy, reduce healthcare‐related costs, and help alleviate medical personnel shortages in under‐resourced settings. However, the development of AI‐enhanced technologies in healthcare is fraught with legal, ethical, and human rights concerns. Currently, the use of AI in South African healthcare is not governed by sui (...) generis legislation or ethical guidance focused exclusively and specifically on AI, although various provisions and principles from law and ethics find application. This article outlines these normative principles and explains their relationship with the extant legal obligations and regulatory framework as applied to the use of AI in radiology services in South Africa. The article concludes with three key recommendations for radiology practitioners using AI in South Africa. These are the need for: vigilant monitoring of AI use in practice, reforms to the liability framework, and appropriate guidance from local regulators and the Health Professions Council of South Africa on the ethical use of AI.

On the phenomenal view of evidence, seemings are evidence. More precisely, if it seems to S that p, S has evidence for p. Here, I raise a worry for this view of evidence; namely, that it has the counterintuitive consequence that two people who disagree would rarely, if ever, share evidence. This is because almost all differences in beliefs would involve differences in seemings. However, many literatures in epistemology, including the disagreement literature and the permissivism literature, presuppose that people who (...) disagree often do share evidence.
