Examination of the fundamental nature of light in mankind's history, world, and life.

Dans le but de d�fendre la th�se de la correspondance entre le comportement moral et le bonheur, j�analyse dans cet article le cas probl�matique des psychopathes. Les psychopathes sont des individus qui ne reculent devant aucun interdit moral pour satisfaire leurs d�sirs, et qui ne ressentent aucun remord ou scrupule face � leurs agissements. En ce sens, ils paraissent obtenir un ��ticket gratuit�� dans le domaine de la moralit�. Comment un d�fenseur de la th�se de la correspondance entre moralit� et (...) bonheur peut-il rendre compte du cas du psychopathe? Le psychopathe vient-il r�futer cette th�se, ou repr�sente-t-il plut�t une exception l�gitime? Je d�fendrai ici une solution alternative �; apr�s avoir propos� une version plausible de la th�se de la correspondance, je tenterai de d�montrer que les psychopathes ne sont pas heureux, et ce en vertu de caract�ristiques essentielles de la psychopathie. Leur statut de ��criminel en puissance�� et leur faible capacit� de contentement sont les deux �l�ments centraux qui m�am�neront � conclure que les psychopathes ne sont pas heureux. Loin de r�futer ou d��chapper � la th�se de la correspondance, le cas des psychopathes vient donc en r�alit� renforcer cette th�se. -/- My goal in this paper is to defend the idea of a general correspondence between happiness and morality, and I do so by analyzing the problematic case of psychopaths. Psychopaths are individuals who are not bothered by moral restrictions when it comes to satisfying their desires. They feel no remorse and have no scruples, and as such they appear to be �free-riders� in the realm of morality. The unusual case of psychopaths will therefore pose a problem to someone who argues that there is a correspondence between happiness and morality: should psychopaths be seen as refuting the correspondence rule, or are they merely a legitimate exception to that rule? I will propose an alternative explanation; after having presented a plausible version of the correspondence thesis, I will try to show that psychopaths, for reasons constitutive of their nature, really are not happy. Psychopaths� quasi-inevitable criminal behaviours as well as their low capacity for contentment are two central elements that lead me to argue that they are not happy. I therefore conclude that psychopaths, far from refuting the correspondence thesis, actually reinforce that thesis. (shrink)

Given the recent interest in the subjective or phenomenal dimension of consciousness it is no wonder that many authors have once more started to speak of the need for pheno- menological considerations. Often however the term ‘phenomenology’ is being used simply as a synonym for ‘folk psychology', and in our article we argue that it would be far more fruitful to turn to the argumentation to be found within the continental tradition inaugurated by Husserl. In order to exemplify this claim, (...) we criticize Rosenthal's higher-order thought theory as well as Strawson's recent contribution in this journal, and argue that a phenomenological analysis of the nature of self-awareness can provide us with a more sophisticated and accurate model for understanding both phenomenal consciousness and the notion of self.

This is a book about how we see: the environment around us (its surfaces, their layout, and their colors and textures); where we are in the environment; whether or not we are moving and, if we are, where we are going; what things are good for; how to do things (to thread a needle or drive an automobile); or why things look as they do.The basic assumption is that vision depends on the eye which is connected to the brain. The (...) author suggests that natural vision depends on the eyes in the head on a body supported by the ground, the brain being only the central organ of a complete visual system. When no constraints are put on the visual system, people look around, walk up to something interesting and move around it so as to see it from all sides, and go from one vista to another. That is natural vision—and what this book is about. (shrink)

Existential phenomenologists hold that the two most basic forms of intelligent behavior, learning, and skillful action, can be described and explained without recourse to mind or brain representations. This claim is expressed in two central notions in Merleau-Ponty's Phenomenology of Perception: the intentional arc and the tendency to achieve a maximal grip. The intentional arc names the tight connection between body and world, such that, as the active body acquires skills, those skills are “stored”, not as representations in the mind, (...) but as dispositions to respond to the solicitations of situations in the world. A phenomenology of skill acquisition confirms that, as one acquires expertise, the acquired know-how is experienced as finer and finer discriminations of situations paired with the appropriate response to each. Maximal grip names the body's tendency to refine its responses so as to bring the current situation closer to an optimal gestalt. Thus, successful learning and action do not require propositional mental representations. They do not require semantically interpretable brain representations either.Simulated neural networks exhibit crucial structural features of the intentional arc, and Walter Freeman's account of the brain dynamics underlying perception and action is structurally isomorphic with Merleau-Ponty's account of the way a skilled agent is led by the situation to move towards obtaining a maximal grip.

Recent studies in developmental psychology have found evidence to suggest that there exists an innate system that accounts for the possibilities of early infant imitation and the existence of phantom limbs in cases of congenital absence of limbs. These results challenge traditional assumptions about the status and development of the body schema and body image, and about the nature of the translation process between perceptual experience and motor ability.

Chris Frith has argued that a loss of the sense of agency is central to schizophrenia. This suggests a connection between hallucinations and delusions on the one hand, and the misidentification of the subject’s imaginings as perceptions and beliefs on the other. In particular, understanding the mechanisms that underlie imagination may help us to explain the puzzling phenomena of thought insertion and withdrawal. Frith sometimes states his argument in terms of a loss of metarepresentational capacity in schizophrenia. I argue that (...) this formulation is unhelpful. (shrink)
