Borderline consciousness, phenomenal consciousness, and artificial consciousness : a unified approachChin, Chuanfei January 2015 (has links)
Borderline conscious creatures are neither definitely conscious nor definitely not conscious. In this thesis, I explain what borderline consciousness is and why it poses a significant epistemological challenge to scientists who investigate phenomenal consciousness as a natural kind. When these scientists discover more than one overlapping kind in their samples of conscious creatures, how can they identify the kind to which all and only conscious creatures belong? After assessing three pessimistic responses, I argue that different groups of scientists can legitimately use the concept of phenomenal consciousness to refer to different kinds, in accord with their empirical interests. They can thereby resolve three related impasses on the status of borderline conscious creatures, the neural structure of phenomenal consciousness, and the possibility of artificial consciousness. The thesis has three parts: First, I analyse the concept of borderline consciousness. My analysis counters several arguments which conclude that borderline consciousness is inconceivable. Then I explain how borderline consciousness produces the multiple kinds problem in consciousness science. Second, I assess three recent philosophical responses to this problem. One response urges scientists to eliminate the concept of consciousness, while another judges them to be irremediably ignorant of the nature of consciousness. The final response concludes that scientific progress is limited by the concept's referential indeterminacy. I argue that these responses are too pessimistic, though they point to a more promising approach. Third, I propose that empirically constrained stipulation can solve the multiple kinds problem. Biologists face the same problem because of their longstanding controversy over what counts as a species. Building on new arguments for stipulating the reference of species concepts, I demonstrate that this use of stipulation in biology is neither epistemologically complacent nor metaphysically capricious; it also need not sow semantic confusion. Then I defend its use in consciousness science. My approach is shown to be consistent with our understanding of natural kinds, borderline cases, and phenomenal consciousness.

Invariance organisationnelle et conscience artificielleBrodeur, Julien 08 1900 (has links)
Ce mémoire se penche sur la possibilité de la conscience artificielle. Plus spécifiquement, je me demande s’il est possible qu’un robot, un ordinateur ou toute autre machine ait une conscience phénoménale, i.e. qu’il y ait un effet que cela fait que d’être ces systèmes. Après avoir brièvement caractérisé la conscience phénoménale, j’investiguerai quelques problèmes qui sont propres à la conscience, soit le problème difficile de la conscience ainsi que le problème des autres esprits, dans le but d’établir le cadre conceptuel qui nous permettra de réfléchir quant à la possibilité de la conscience artificielle. Dans le deuxième chapitre, je défendrai la thèse selon laquelle la conscience artificielle est possible en m’appuyant notamment sur le principe d’invariance organisationnelle défendu, entre autres, par David Chalmers, ainsi que sur la théorie computationnelle de l’esprit. Finalement, dans le troisième et dernier chapitre, j’évaluerai diverses objections contre la possibilité de la conscience artificielle que je tenterai tour à tour de réfuter dans le but maintenir ma thèse initiale aussi intacte que possible. / This thesis examines the possibility of artificial consciousness. More specifically, I consider the possibility for a robot, computer or any other machine to have phenomenal consciousness, i.e. that there is something it is like to be those systems. After having briefly characterized phenomenal consciousness, I will investigate some problems that are specific to consciousness, namely the hard problem of consciousness as well as the problem of other minds, in order to establish the conceptual framework that will allow us to reflect upon the possibility of artificial consciousness. In the second chapter, I will defend the thesis that artificial consciousness is possible by relying on the principle of organizational invariance which is defended by David Chalmers, among others, as well as on the computational theory of the mind. Finally, in the third and last chapter, I will assess various objections against the possibility of artificial consciousness which I will try to refute in turn in order to keep my initial thesis as intact as possible.
