Un système cognitif sans neurones

John STEWART : Cognition without Neurones : Adaptation, Learning and Memory in the Immune System This paper proposes a definition of cognition as a system capable of both action and perception, in which the coupling of action and perception is such that the emergent behaviour of the system in its environment satisfies a meaningful constraint. The immune system of vertebrate animals reacts to nonself antigens by producing a specific immune response which triggers destruction of the antigen ; it reacts to self antigens by incorporating them into the regulatory dynamics of a self-organizing network. It is argued that this behaviour meets the requirements of the definition, and hence that the immune system is a cognitive entity capable of adaptation, learning and memory. Consequences of this perspective are that the molecules and cells of a multicellular organism are not, as such, "cognitive" ; that the full articulation of neurophysiology into cognitive science requires a study of emergent behaviour at the level of meaningful interactions between a system and its environment ; and that the objects of cognition, with or without neurones, are brought into existence by the coupled perceptions and actions of the cognitive system itself
