Conscious visual perception can fail in many circumstances. However, little is known about the causes and processes leading to failures of visual awareness. In this study, we introduce a new signal detection measure termed subjective discriminability of invisibility that allows one to distinguish between subjective blindness due to reduction of sensory signals or to lack of attentional access to sensory signals. The SDI is computed based upon subjective confidence in reporting the absence of a target . Using this new measure, (...) we found that target misses were subjectively indistinguishable from physical absence when contrast reduction, backward masking and flash suppression were used, whereas confidence was appropriately modulated when dual task, attentional blink and spatial uncertainty methods were employed. These results show that failure of visual perception can be identified as either a result of perceptual or attentional blindness depending on the circumstances under which visual awareness was impaired.

In their target article, Rips et al. have presented the view that there is no necessary dependency between natural numbers and internal magnitude. However, they do not give enough weight to neuroimaging and neuropsychological studies. We provide evidence demonstrating that the acquisition of natural numbers depends on magnitude representation and that natural numbers develop from a general magnitude mechanism in the parietal lobes.

The study of neuronal specialisation in different cognitive and perceptual domains is important for our understanding of the human brain, its typical and atypical development, and the evolutionary precursors of cognition. Central to this understanding is the issue of numerical representation, and the question of whether numbers are represented in an abstract fashion. Here we discuss and challenge the claim that numerical representation is abstract. We discuss the principles of cortical organisation with special reference to number and also discuss methodological (...) and theoretical limitations that apply to numerical cognition and also to the field of cognitive neuroscience in general. We argue that numerical representation is primarily non-abstract and is supported by different neuronal populations residing in the parietal cortex. (shrink)

In this commentary we make two rejoinders to Jung & Haier (J&H). First, we highlight the response selection component in tasks as a confounding variable that may explain the parieto-frontal involvement in studies of human intelligence. Second, we suggest that efficient response selection may be an integral part of the definition of intelligence.

Neuropsychological patients exhibiting category-selective visual agnosias provide unique insights into the cognitive functions of the human brain. Transcranial magnetic stimulation, in contrast, can be used to draw causal inferences, as one of the effects of the cortical disruption induced by magnetic stimulation is to act as a “virtual lesion” lasting from tens of milliseconds up to approximately one hour, depending on the type of stimulation. This specificity offers a unique advantage in psychological testing as TMS can be used to test (...) where and when cognitive computations are performed. This article briefly describes TMS, considers the small but growing number of studies that use TMS to disrupt face processing. It discusses how TMS can be used in the future to understand better how faces are cortically represented in the human brain. (shrink)

The commentators have raised many pertinent points that allow us to refine and clarify our view. We classify our response comments into seven sections: automaticity; developmental and educational questions; priming; multiple representations or multiple access(?); terminology; methodological advances; and simulated cognition and numerical cognition. We conclude that the default numerical representations are not abstract.

A key question in understanding visual awareness is whether any single cortical area is indispensable. In a transcranial magnetic stimulation experiment, we show that observers' awareness of activity in extrastriate area VS depends on the amount of activity in striate cortex (Vl). From the timing and pattern of effects, we infer that back-projections from extrastriate cortex influence information content in Vl, but it is Vl that determines whether that information reaches awareness.

We concur with Cohen Kadosh & Walsh (CK&W) that representation of numbers in the parietal cortex is format dependent. In addition, we suggest that all formats do not automatically, and equally, access analog magnitude representation in the intraparietal sulcus (IPS). Understanding how development, learning, and context lead to differential access of analog magnitude representation is a key question for future research.

Cohen Kadosh & Walsh (CK&W) neglect the solid empirical evidence for a convergence of notation-specific representations onto a shared representation of numerical magnitude. Subliminal priming reveals cross-notation and cross-modality effects, contrary to CK&W's prediction that automatic activation is modality and notation-specific. Notation effects may, however, emerge in the precision, speed, automaticity, and means by which the central magnitude representation is accessed.

This paper presents the main topics, arguments, and positions in the philosophy of AI at present (excluding ethics). Apart from the basic concepts of intelligence and computation, the main topics of ar-tificial cognition are perception, action, meaning, rational choice, free will, consciousness, and normativity. Through a better understanding of these topics, the philosophy of AI contributes to our understand-ing of the nature, prospects, and value of AI. Furthermore, these topics can be understood more deeply through the discussion of AI; so (...) we suggest that “AI Philosophy” provides a new method for philosophy. (shrink)

This paper argues for a Husserlian account of phenomenal intentionality. Experience is intentional insofar as it presents a mind-independent, objective world. Its doing so is a matter of the way it hangs together, its having a certain structure. But in order for the intentionality in question to be properly understood as phenomenal intentionality, this structure must inhere in experience as a phenomenal feature. Husserl’s concept of horizon designates this intentionality-bestowing experiential structure, while his concept of motivation designates the unique phenomenal (...) character of this structure as it is experientially lived through. The way experience hangs together is itself a phenomenal feature of experience. (shrink)

This chapter analyses the theology of Soren Kierkegaard. It explains that Kierkegaard was trained in the theology of the Evangelical Lutheran Church of Denmark and was well-versed in the subject, but did not consider himself as a theologian. The chapter suggests that his main theological project was the reintroduction of Christianity into Christendom or the ecclesiastical-sociopolitical established order. Kierkegaard believes that Christianity is not a doctrine but an ‘existence-communication’ and a subjective truth that is to be actualized in existence with (...) the object of existing in it through faith.

How do people understand questions about cause and prevent? Some theories propose that people affirm that A causes B if A's occurrence makes a difference to B's occurrence in one way or another. Other theories propose that A causes B if some quantity or symbol gets passed in some way from A to B. The aim of our studies is to compare these theories' ability to explain judgements of causation and prevention. We describe six experiments that compare judgements for causal (...) paths that involve a mechanism, i.e. a continuous process of transmission or exchange from cause to effect, against paths that involve no mechanism yet a change in the cause nevertheless brings about a change in the effect. Our results show that people prefer to attribute cause when a mechanism links cause to effect. In contrast, prevention is sensitive both to the presence of an interruption to a causal mechanism and to a change in the outcome in the absence of a mechanism. In this sense, ‘prevent’ means something different than ‘cause not'. We discuss the implications of our results for existing theories of causation. (shrink)

We present an analogue of Gödel’s second incompleteness theorem for systems of second-order arithmetic. Whereas Gödel showed that sufficiently strong theories that are $\Pi ^0_1$ -sound and $\Sigma ^0_1$ -definable do not prove their own $\Pi ^0_1$ -soundness, we prove that sufficiently strong theories that are $\Pi ^1_1$ -sound and $\Sigma ^1_1$ -definable do not prove their own $\Pi ^1_1$ -soundness. Our proof does not involve the construction of a self-referential sentence but rather relies on ordinal analysis.

While it is often said that robotics should aspire to reproducible and measurable results that allow benchmarking, I argue that a focus on benchmarking can be a hindrance for progress in robotics. The reason is what I call the ‘measure-target confusion’, the confusion between a measure of progress and the target of progress. Progress on a benchmark (the measure) is not identical to scientific or technological progress (the target). In the past, several academic disciplines have been led into pursuing only (...) reproducible and measurable ‘scientific’ results – robotics should be careful to follow that line because results that can be benchmarked must be specific and context-dependent, but robotics targets whole complex systems for a broad variety of contexts. While it is extremely valuable to improve benchmarks to reduce the distance be- tween measure and target, the general problem to measure progress towards more intelligent machines (the target) will not be solved by benchmarks alone; we need a balanced approach with sophisticated benchmarks, plus real-life testing, plus qualitative judgment.

There is, in some quarters, concern about high–level machine intelligence and superintelligent AI coming up in a few decades, bringing with it significant risks for humanity. In other quarters, these issues are ignored or considered science fiction. We wanted to clarify what the distribution of opinions actually is, what probability the best experts currently assign to high–level machine intelligence coming up within a particular time–frame, which risks they see with that development, and how fast they see these developing. We thus (...) designed a brief questionnaire and distributed it to four groups of experts in 2012/2013. The median estimate of respondents was for a one in two chance that high-level machine intelligence will be developed around 2040-2050, rising to a nine in ten chance by 2075. Experts expect that systems will move on to superintelligence in less than 30 years thereafter. They estimate the chance is about one in three that this development turns out to be ‘bad’ or ‘extremely bad’ for humanity. (shrink)

This book explores the emergence of the modern higher education sector in the independent Irish state. The author traces its origins from the traditional universities, technical schools and teacher training colleges at the start of the twentieth century, cataloguing its development into the complex, multi-layered and diverse system of the early twenty-first century. Focusing on the socio-political and cultural contexts which shaped the evolution of higher education, the author analyses the interplay between the state, academic institutions and other key institutional (...) actors - notably churches, cultural organizations, employers, trade unions and supranational bodies. This study explores policy, structural and institutional change in Irish higher education, suggesting that the emergence of the modern higher education system in Ireland was influenced by ideologies and trends which owed much to a wider European and international context. The book considers how the exercise of power at local, national and international level impinged on the mission, purpose and values of higher education and on the creation and expansion of a distinctive higher education system. The author also explores a transformation in public and political understandings of the role of higher education, charting the gradual evolution from traditionalist conceptions of the academy as a repository for cultural and religious value formation, to the re-positioning of higher education as a vital factor in the knowledge based economy. This comprehensive volume will appeal to students and scholars of the Irish education system, educators and practitioners in the field, and those interested in higher education in Ireland more generally.

Cognition is commonly taken to be computational manipulation of representations. These representations are assumed to be digital, but it is not usually specified what that means and what relevance it has for the theory. I propose a specification for being a digital state in a digital system, especially a digital computational system. The specification shows that identification of digital states requires functional directedness, either for someone or for the system of which it is a part. In the case or digital (...) representations, to be a token of a representational type, where the function of the type is to represent.

In The Priority of the Person, world-class philosopher David Walsh advances the argument set forth in his highly original philosophic meditation Politics of the Person as the Politics of Being (2015), that "person" is the central category of modern political thought and philosophy. This book is divided into three main parts. Beginning with the political discovery of the inexhaustibility of persons, it then explores the philosophic differentiation of the idea of the "person," and finally traces its historical emergence through (...) art, science, and faith. Walsh argues that, although the roots of the idea of "person" are found in the Greek concept of the mind and in the Christian conception of the soul, this notion is ultimately a distinctly modern achievement, because it is only the modern turn toward interiority that illuminated the unique nature of persons as each being a world unto him or herself. As Walsh shows, it is precisely this feature of persons that makes it possible for us to know and communicate with others, for we can only give and receive one another as persons. In this way alone can we became friends and, in friendship, build community. In showing how the person is modernity's central preoccupation, and in demonstrating how it is only as persons that we can truly give ourselves to others and thus develop real community, David Walsh's The Priority of the Person makes an important contribution to current discussions in both political theory and philosophy. It will also appeal to students and scholars of theology and literature, and any groups interested in the person and personalism. (shrink)

La religion ne serait-elle que déraison ?

Kierkegaard’s psychological thought has always been acknowledged as very rich—Reinhold Niebuhr hailed him as the greatest psychologist of the soul since Augustine—and has had a major influence on Heidegger, Sartre, and existential psychoanalysis. Nevertheless, his accomplishment has not always been fully appreciated, in part because it is so scattered across his works. As Vincent McCarthy demonstrates in Kierkegaard as Psychologist, Kierkegaard was pursuing “psychology” before there was a formally recognized academic field bearing that name, and a coherent thread runs (...) through the so-called pseudonymous works. McCarthy elucidates often-difficult texts, highlights the rich psychological dimension of Kierkegaard’s thought, and provides an introduction for the nonspecialist and a commentary on Kierkegaard’s psychology that will interest both specialists and nonspecialists, while engaging in rich comparisons with such figures as Freud and Heidegger.

Few issues cause academics to disagree more than gender and race, especially when topics are addressed in terms of biological differences. To conduct research in these areas or comment favorably on research can subject one to scorn. When these topics are addressed, they generally take the form of philosophical debates. Anthony Walsh focuses upon such debates and supporting research. He divides parties into biologists and social constructionists, arguing that biologists remain focused on laboratory work, while constructionists are acutely aware (...) of the impact of biologists in contested territories. "Science Wars" introduces the ideas motivating the parties and examines social constructionism and its issues with science. He explores arguments over conceptual tools scientists love and constructionists abhor, and he provides a solid discussion of the co-evolution of genes and culture. Walsh then focuses his attention on gender, how constructionists view it, and the neuroscience explanation of gender differences. Moving to race, Walsh looks at how some have tried to bury the concept of race, while others emphasize it. He considers definitions of race--essentialist, taxonomic, population, and lineage--as they have evolved from the time of the Enlightenment to the present. And finally, he attempts to bring the opposing sides together by pointing out what each can bring to a meaningful discussion. (shrink)

The philosophy of AI has seen some changes, in particular: 1) AI moves away from cognitive science, and 2) the long term risks of AI now appear to be a worthy concern. In this context, the classical central concerns – such as the relation of cognition and computation, embodiment, intelligence & rationality, and information – will regain urgency.

La 4e de couverture indique : "Michel Henry - bien que considéré comme un penseur de la "vie" et des "vivants" - n'a cessé de méditer le fameux memento mori, marque insigne de la destinée de la philosophie. Comme philosophe de la subjectivité, il a identifié la vie à "ce qui ne peut pas mourir", rompant ainsi avec ce qu'il y avait de moribond dans l'onto-thanatologie heideggérienne d'Être et Temps. Cet ouvrage élucide et interprète ces rapports entre la vie et (...) la mort, l'être et le temps. Mais il pose une question de fond : en pensant la vie comme auto-révélation et auto-affection, Michel Henry n'aurait-il pas, de façon idéaliste, esquivé le phénomène incontestable et brutal de la mort, voire barré, par principe, une humaine intelligibilité de ce dernier? En interrogeant l'élaboration henryenne des tensions conceptuelles entre une sotériologie rigoureusement philosophique et les paradoxes de l'eschatologie religieuse, le livre montre les enjeux mais aussi les faiblesses - ou les oublis - de la phénoménologie henryenne quand elle doit bien faire face à la mort.".
