Neural correlates of consciousnessThe neural correlates of consciousness (NCC) refer to the relationships between mental states and neural states and constitute the minimal set of neuronal events and mechanisms sufficient for a specific conscious percept. Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena; that is, neural changes which necessarily and regularly correlate with a specific experience.
Quel effet cela fait-il d'être une chauve-souris ?Quel effet cela fait-il d’être une chauve-souris ? (What is it like to be a bat?) est un article du philosophe Thomas Nagel écrit en et paru pour la première fois dans la revue américaine The Philosophical Review (, 4). Nagel y développe la thèse selon laquelle nous n’avons aucun moyen de savoir quelle expérience subjective du monde fait une chauve-souris. Le seul moyen d'y accéder serait en effet d’être soi-même une chauve-souris. Ainsi les qualia échappent-ils à l’analyse, et l’investigation scientifique de la conscience semble, par là même, impossible.
Subjective character of experienceThe subjective character of experience is a term in psychology and the philosophy of mind denoting that all subjective phenomena are associated with a single point of view ("ego"). The term was coined and illuminated by Thomas Nagel in his famous paper "What Is it Like to Be a Bat?" Nagel argues that, because bats are apparently conscious mammals with a way of perceiving their environment entirely different from that of human beings, it is impossible to speak of "what is it like to be a bat for the bat" or, while the example of the bat is particularly illustrative, any conscious species, as each organism has a unique point of view from which no other organism can gather experience.
Further factsIn philosophy, further facts are facts that do not follow logically from the physical facts of the world. Reductionists who argue that at bottom there is nothing more than the physical facts thus argue against the existence of further facts. The concept of further facts plays a key role in some of the major works in analytic philosophy of the late 20th century, including in Derek Parfit's Reasons and Persons, and David Chalmers's The Conscious Mind.
