We often feel that our perceptual experience is richer than what we can express. For instance, when flashed with a large set of letters, we feel that we can see them all, while we can report only a few. However, the nature of this subjective impression remains highly debated: while many favour a dissociation between two forms of consciousness , others contend that the richness of phenomenal experience is a mere illusion. Here we addressed this question with a classical partial-report (...) paradigm now modified to include unexpected items in the unreported parts of the stimuli. We show that even in the presence of unexpected pseudo-letters, participants still felt that there were only letters. Additionally, we show that this feeling reflects an illusion whereby participants reconstruct letters using partial letter-like information. We propose that the feeling of seeing emerges from the interplay between partially accessible information and expectations. (shrink)

On identifie deux modèles du concept de règle présents dans l’œuvre de Wittgenstein, dès le Tractatus : les règles de projection (ou de traduction) et les règles opératoires (ou de calcul). Dans le cadre conceptuel de ce texte, gouverné par l’indépendance des propositions élémentaires, ces deux modèles sont équivalents. On interprète ensuite les difficultés de Wittengstein avec le concept de phénoménologie, au début des années trente, comme liées à la restriction du concept de règle aux règles de projection. Le dépassement (...) de ces difficultés se fait par la découverte de la possibilité d’un nouvel équilibre entre les deux modèles, équilibre dans lequel les règles opératoires jouent un rôle directeur.

Amidst the many brain events evoked by a visual stimulus, which are specifically associated with conscious perception, and which merely reflect non-conscious processing? Several recent neuroimaging studies have contrasted conscious and non-conscious visual processing, but their results appear inconsistent. Some support a correlation of conscious perception with early occipital events, others with late parieto-frontal activity. Here we attempt to make sense of those dissenting results. On the basis of a minimal neuro-computational model, the global neuronal workspace hypothesis, we propose a (...) taxonomy which distinguishes between vigilance and access to conscious report, as well as between subliminal, preconscious and conscious processing. We suggest that these distinctions map onto different neural mechanisms, and that conscious perception is systematically associated with a sudden surge of parieto-frontal activity causing top-down amplification.

Sackur joins several other recent French authors in writing penetrating analyses of Russell’s and Wittgenstein’s work. Forms and Factsz is an explication of the Tractatus, conducted by means of a contrast between Russell’s work and Wittgenstein’s. Sackur examines the interplay between Russell’s and Wittgenstein ’s versions of logical atomism, particularly, as Sackur puts it, between Russell’s original thought on the one hand, which provides the material for Wittgenstein’s position in the Tractatus, and Wittgenstein’s critique and development on the other, which, he says, provides a unity to Russell’s position (p. 12). While recognizing the inXuence of Russell on Wittgenstein’s project, Sackur in the end sees Wittgenstein as undermining and ultimately rejecting Russell’s logicism. He does not just repeat old claims about Wittgenstein, Russell and logical form. His analysis is very subtle and, perhaps unusually for a work on Wittgenstein which defends Wittgenstein over Russell, Formes et faitsz displays a surprisingly detailed knowledge of Russell’s work, before, during and after the period in question, 1913–19. Anyone who is interested in Russell’s and Wittgenstein ’s work during this period, and in particular Wittgenstein’s criticisms of Russell, will beneWt greatly from this book. There are detailed, well informed discussions of important points of disagreement, particularly Russell and Whitehead ’s account of succession and the ancestor relation, Wittgenstein’s remarks on operators, in particular the Nz operator, various remarks about the theory of types, and Wittgenstein’s now well known criticism of Russell’s theory of judgment. The subtitle of the work, “Analysis and the theory of knowledge in logical atomism”, reXects the points where Sackur sees the greatest disagreement between Russell and Wittgenstein. In the Wrst place, he sees them diTering in their attitude toward analysis, with Russell oTering translations of sentences into a September 27, 2008 (1:09 pm) G:\WPData\TYPE2801\russell 28,1 048RED.wpd 70 Reviews 1 For the Wrst point, see (among others) P.yM.yS.

Secondly, they diTer on the role that epistemology should play in logical atomism, with Wittgenstein criticizing the role of acquaintance in the development of logic. While both of these points have been made before,1 Sackur’s discussion is more thorough than previous studies and leads to some new interpretations of passages in the Tractatus. Sackur’s discussion of analysis is important to his argument. He is interested in a tension between what he sees as two aims of analysis in Wittgenstein’s work, one found in Tractatusz 3.2–3.3 and the other in Tractatusz 4.21–4.2211. He sees analysis in the Wrst group as revealing or elucidating the sense a proposition expresses, a sense understood and already there in the ordinary unanalyzed proposition, and analysis in the second group, driven by the theses of necessity and logical independence, as focusing on truth-functional analysis in terms of elementary propositions that consist of names referring to simple objects. He argues that these two aims don’t automatically go together and in fact appear to be at cross purposes. In the course of the Wrst chapter, the major distinction Sackur makes is between analysis...

First published in 1977, Emotion, Thought and Therapy is a study of Hume and Spinoza and the relationship of philosophical theories of the emotions to psychological theories of therapy. Jerome Neu argues that the Spinozists are closer to the truth; that is, that thoughts are of greater importance than feelings in the classification and discrimination of emotional states. He then contends that if the Spinozists are closer to the truth, we have the beginning of an argument to show that Freudian (...) or analytic therapies make philosophic sense. Throughout the book, careful attention is paid to modern discussions in philosophy of mind and psychology, and materials from anthropology and other relevant disciplines are considered. At the centre of the discussion is the notion of ‘thought-dependence’. Therapies for psychological disorders are placed along a spectrum in accordance with the role they assign to thoughts. The Spinozist view of the emotions can be seen as at the extreme thought end of a corresponding spectrum of theories of the emotions. The book suggests that this stream may help explain the spectrum of therapeutic theories and the possibilities that exist for psychological development and change. This book will be of interest to students of philosophy, psychology and counselling. (shrink)

Christopher Boorse’s biostatistical theory of medical disorder claims that biological part-dysfunction (i.e., failure of an internal mechanism to perform its biological function), a factual criterion, is both necessary and sufficient for disorder. Jerome Wakefield’s harmful dysfunction analysis of medical disorder agrees that part-dysfunction is necessary but rejects the sufficiency claim, maintaining that disorder also requires that the part-dysfunction causes harm to the individual, a value criterion. In this paper, I present two considerations against the sufficiency claim. First, I analyze Boorse’s (...) central argument for the sufficiency claim, the “pathologist argument,” which takes pathologists’ intuitions about pathology as determinative of medical disorder and conclude that it begs the question and fails to support the sufficiency claim. Second, I present four counterexamples from the medical literature in which salient part-dysfunctions are considered nondisorders, including healthy disease carriers, HIV-positive status, benign mutations, and situs inversus totalis, thus falsifying the sufficiency claim and supporting the harm criterion.

Much of our understanding of human thinking is based on probabilistic models. This innovative book by Jerome R. Busemeyer and Peter D. Bruza argues that, actually, the underlying mathematical structures from quantum theory provide a much better account of human thinking than traditional models. They introduce the foundations for modelling probabilistic-dynamic systems using two aspects of quantum theory. The first, 'contextuality', is a way to understand interference effects found with inferences and decisions under conditions of uncertainty. The second, 'quantum entanglement', (...) allows cognitive phenomena to be modeled in non-reductionist ways. Employing these principles drawn from quantum theory allows us to view human cognition and decision in a totally new light. Introducing the basic principles in an easy-to-follow way, this book does not assume a physics background or a quantum brain and comes complete with a tutorial and fully worked-out applications in important areas of cognition and decision.

This paper presents a general computational treatment of how mammals are able to deal with visual objects and environments. The model tries to cover the entire range from behavior and phenomenological experience to detailed neural encodings in crude but computationally plausible reductive steps. The problems addressed include perceptual constancies, eye movements and the stable visual world, object descriptions, perceptual generalizations, and the representation of extrapersonal space.The entire development is based on an action-oriented notion of perception. The observer is assumed to (...) be continuously sampling the ambient light for information of current value. The central problem of vision is taken to be categorizing and locating objects in the environment. The critical step in this process is the linking of visual information to symbolic object descriptions; this is calledindexing, from the analogy of identifying a book from index terms. The system must also identifysituationsand use this knowledge to guide movement and other actions in the environment. The treatment focuses on the different representations of information used in the visual system.The four representational frames capture information in the following forms: retinotopic, head-based, symbolic, and allocentric. The functional roles of the four frames, the communication among them, and their suggested neurophysiological realization constitute the core of the paper. The model is perforce crude, but appears to be consistent with all relevant findings. (shrink)

Wakefield’s harmful dysfunction analysis asserts that the concept of medical disorder includes a naturalistic component of dysfunction and a value component, both of which are required for disorder attributions. Muckler and Taylor, defending a purely naturalist, value-free understanding of disorder, argue that harm is not necessary for disorder. They provide three examples of dysfunctions that, they claim, are considered disorders but are entirely harmless: mild mononucleosis, cowpox that prevents smallpox, and minor perceptual deficits. They also reject the proposal that dysfunctions (...) need only be typically harmful to qualify as disorders. We argue that the proposed counterexamples are, in fact, considered harmful; thus, they fail to disconfirm the harm requirement: incapacity for exertion is inherently harmful, whether or not exertion occurs, cowpox is directly harmful irrespective of indirect benefits, and colorblindness and anosmia are considered harmful by those who consider them disorders. We also defend the typicality qualifier as viably addressing some apparently harmless disorders and argue that a dysfunction’s harmfulness is best understood in dispositional terms. (shrink)

In ‘Rethinking Disease’, Powell and Scarffe1 propose what in effect is a modification of Jerome Wakefield’s2 3 harmful dysfunction analysis of medical disorder. The HDA maintains that ‘disorder’ is a hybrid factual and value concept requiring that a biological dysfunction, understood as a failure of some feature to perform a naturally selected function, causes harm to the individual as evaluated by social values. Powell and Scarffe accept both the HDA’s evolutionary biological function component and its incorporation of a value component. (...) Their proposed ‘new twist’ is to revise the value component: ‘Our proposed definition of disease is as follows: a biomedical state is a disease only if it implicates a biological dysfunction that is, or would be, properly disvalued’. So, they propose that a disorder is a ‘properly disvalued dysfunction’ rather than a ‘harmful dysfunction’, an approach they term ‘thickly normative’ in contrast to the thin normative approach of the HDA. There has been a surge of interest recently in better understanding the ‘harm’ component of the HDA. Powell and Scarffe’s analysis is a helpful contribution to this discussion. We focus here exclusively on their proposal regarding the analysis of the concept of disorder and ignore many important related issues that the authors address, ranging from prioritising resource allocation between disorders and non-disorders to whether the concept of disorder should be replaced by a generic welfarist concept. The resolution of these additional issues depends on first understanding ‘disorder’. The authors’ proposed changes to the HDA also deserve evaluation because the HDA, which has been endorsed by leading nosologists,4 plays an influential role in nosological debate across categories of disorder ranging, for example, from sexual paraphilias5 to psychopathy.6 A basic problem is that Powell and Scarffe misinterpret ….

This remarkable book is the most comprehensive study ever written of the history of moral philosophy in the seventeenth and eighteenth centuries. Its aim is to set Kant's still influential ethics in its historical context by showing in detail what the central questions in moral philosophy were for him and how he arrived at his own distinctive ethical views. The book is organised into four main sections, each exploring moral philosophy by discussing the work of many influential philosophers of the (...) seventeenth and eighteenth centuries. In an epilogue the author discusses Kant's view of his own historicity, and of the aims of moral philosophy. In its range, in its analyses of many philosophers not discussed elsewhere, and in revealing the subtle interweaving of religious and political thought with moral philosophy, this is an unprecedented account of the evolution of Kant's ethics.

This, the third edition of Fundamentals of Experimental Design, has five added chapters - those on regression (Chapters 12, 14, and 15), multivariate analysis (Chapter 18), and the matrix algebra appropriate to the level of presentation of this material (Chapter 13). I have noted in the preface other additions in this third edition. The added material should enhance the value of the book as a textbook and a reference. Given these additions, however, alternative approaches in using the current edition as (...) a textbook may merit consideration. It may help to note that Chapters 16 and 17 (analysis of covariance, trend analysis) do not depend on the material in Chapters 12 through 15, although the student should know something about simple linear regression to be able to understand fully the material in Chapters 16 and 17. In any event, the instructor who wants to teach only the material in the first two editions can do so by dropping the added chapters - 12 through 15, and 18 - from the syllabus. (shrink)

The book introduces Ramsey's main doctrines and assesses their contemporary significance. In particular, Jérôme Dokic and Pascal Engel are interested in Ramsey's thoughts on truth and belief, and his pragmatic thesis that the truth of one's beliefs guarantees the success of one's actions. From this, it is a short step to what may be called "Ramsey's principle": the content of a belief is constituted by the success of one's actions. This principle finds its current expression in the work of (...) philosophers who offer evolutionary conceptions of mental states, according to which the success conditions of a belief are constituted by its biological functions.
