Ninety-one right brain-damaged patients with left neglect and 43 right brain-damaged patients without neglect were asked to extend horizontal segments, either left- or rightward, starting from their right or left endpoints, respectively. Earlier experiments based on similar tasks had shown, in left neglect patients, a tendency to overextend segments toward the left side. This seemingly paradoxical phenomenon was held to undermine current explanations of unilateral neglect. The results of the present extensive research demonstrate that contralesional overextension is also evident in (...) most right brain-damaged patients without contralesional neglect. Furthermore, they show that in a minority of left neglect patients, the opposite behavior, i.e., right overextension can be found. The paper also reports the results of correlational analyses comprising the parameters of line-extension, line-bisection, and cancellation tasks, as well as the parameters relative to the Milner Landmark Task, by which a distinction is drawn between perceptual and response biases in unilateral neglect. A working hypothesis is then advanced about the brain dysfunction underlying neglect and an attempt is made at finding an explanation of neglect and the links between the mechanisms of space representation and consciousness through the study of the changes induced by unilateral brain lesions in the characteristics of space-coding neurons.

The significance of consciousness in modern science is discussed by leading authorities from a variety of disciplines. Presenting a wide-ranging survey of current thinking on this important topic, the contributors address such issues as the status of different aspects of consciousness; the criteria for using the concept of consciousness and identifying instances of it; the basis of consciousness in functional brain organization; the relationship between different levels of theoretical discourse; and the functions of consciousness.

When left-neglect patients are required to extend horizontal segments to double their original length, relative left overextension is frequently observed. Less frequently, relative left underextension may also be found. It was hypothesized that this contrast could depend on the degree of horizontal anisometry of the medium for the representation of spatial properties. The present paper reports an experiment conducted in order to test that hypothesis, on the basis of which left overextension should be larger with shorter than with longer segments (...) and with segments lying in the right rather than in the left hemispace. Although supportive, the results unveiled unexpected complications: the expected effect of line length was found only in neglect patients with frontal damage, while the expected effect of side of presentation was found only in neglect patients without frontal damage.

Durkheim écrit ce livre avec un but double : d'abord il voulait expliquer ce qui crée une société, ce qui la tient ensemble ; ensuite il voulait éclaircir l'influence qu'a la société sur la pensée logique. Pour Durkheim, la religion est la clé utilisée pour déverrouiller ces deux problématiques.Dans ce livre, Durkheim argumente que les représentations religieuses sont en fait des représentations collectives : l'essence du religieux ne peut être que le sacré. Il est une caractéristique qui se trouve universellement (...) dans toutes les religions. Le sacré, être collectif et impersonnel, représente ainsi la société elle-même. Ensuite il argumente que la société a un impact majeur dans la genèse de la pensée logique. C'est la société qui fournit à l'individu les catégories (le temps, l'espace, le nombre etc.) et les concepts nécessaires pour la pensée logique. (shrink)

When we perceive an object, we perceive the object from a perspective. As a consequence of the perspectival nature of perception, when we perceive, say, a circular coin from different angles, there is a respect in which the coin looks circular throughout, but also a respect in which the coin's appearance changes. More generally, perception of shape and size properties has both a constant aspect—an aspect that remains stable across changes in perspective—and a perspectival aspect—an aspect that changes depending on (...) one's perspective on the object. How should we account for the perspectival aspect of spatial perception? We present a framework within which to discuss the perspectival aspect of perception and put forward three desiderata that any account of the perspectival aspect of perception should satisfy. We discuss views on which the perspectival aspect of perception is analyzed in terms of constitutively mind-dependent appearance properties as well as views on which the perspectival aspect of perception is analyzed in terms of representations of mind-independent perspectival properties.

With special emphasis on Foucault's many recently published lecture series this book provides an updated, comprehensive presentation of his most important diagnoses, his many ground-breaking analytical concepts as well as a systematic account of his unique conception of philosophy.

We argue that the trend toward providing users with feasible and actionable explanations of AI decisions—known as recourse explanations—comes with ethical downsides. Specifically, we argue that recourse explanations face several conceptual pitfalls and can lead to problematic explanation hacking, which undermines their ethical status. As an alternative, we advocate that explanations of AI decisions should aim at understanding.

A dialogue between a foreign philosopher and a powerful statesman outline Plato's reflections on the family, the status of women, property rights, and criminal law.

The Anthropocene is heralded as a new epoch distinguishing itself from all foregoing eons in the history of the Earth. It is characterized by the overarching importance of the human species in a number of respects, but also by the recognition of human dependence and precariousness. A critical human turn affecting the human condition is still in the process of arriving in the wake of an initial Copernican Revolution and Kant's ensuing second Copernican Counter-revolution. Within this landscape, issues concerning the (...) human - its finitude, responsiveness, responsibility, maturity, auto-affection and relationship to itself - appear rephrased and re-accentuated as decisive probing questions. In this book Sverre Raffnsøe explores how the change has ramifications for the kinds of knowledge that can be acquired concerning human beings and for the human sciences as a study of human existential beings in the world.

Criticism on Bhagavadgītā, Hindu sacred work.

What makes us human is our special motivation to share with others how we feel, what we believe, and what we want to happen in the future. We want to share with others what is real about the world. Shared reality is crucial to what we believe--sharing is believing. It is central to our sense of self, what we strive for and how we strive. It is basic to how we get along with others. It brings us together in fellowship (...) and companionship, but it also tears us apart by creating in-group "bubbles" that conflict with one another. Our shared realities are the best of us, and the worst of us. (shrink)

Etienne Gilson Reason and Revelation in the Middle Ages, first delivered as the Richard Lectures in 1937, was published in 1938 and became an immediate success. Not only does it contribute to a major question of debate in Christian, Jewish, and Islamic philosophy and religion in the medieval period but it also insists on the validity of truth obtainable through reason as well as revelation, on rational argument alongside religious faith. This message is as important in the twenty-first century as (...) it was in the fourth century of the young Augustine, the thirteenth of St Thomas Aquinas, and the twentieth of the mature Gilson.

A collection of Essays over the last 20 years, exploring different dimensions of the philosophical debate on "subjecthood" and "subjectivity" in Modernity, as it was framed by the "Controversy on the subject" from the 1960's, and showing how it is now continued in a "controversy on the Universal.".

This article critically reflects on the research portfolio by the ecological economist Clive Spash who has helped pinpoint specific and systemic blindspots in a political-economic system that prioritises myopic development trajectories divorced from ecological reality. Drawing on his published work and collaborations it seeks to make sense of the slow, or absent, progress in averting global warming and ecological destruction. Three strands of key concern and influence are identified and discussed with reference to their orientation and explicit expression regarding Ontology, (...) Epistemology and Axiology. Some complementary points about indeterminacy and holism are presented to further strengthen the arguments for a transition towards a social-ecological economic system that puts values and principles back into focus. While Clive Spash's work has made a strong case within the economic community and appealing to ecology professionals, the value-myopia or value-vacuum has to be tackled across all disciplines, politics and society for a meaningful and urgently required transformation in decision making. Hence, the article finishes with some suggestions for the (higher) education system, and highlights the importance of simplicity and sufficiency, as well as strong sustainability-driven citizen and community action as necessary catalysts of change in this social-ecological transformation.
