'Representation' is a concept which occurs both in cognitive science and philosophy. It has common features in both settings in that it concerns the explanation of behaviour in terms of the way the subject categorizes and systematizes responses to its environment. The prevailing model sees representations as causally structured entities correlated on the one hand with elements in a natural language and on the other with clearly identifiable items in the world. This leads to an analysis of representation and cognition (...) in terms of formal symbols and their relations. But human perception and cognition use multiple informational constraints and deal with unsystematic and messy input in a way best explained by Parallel Distributed Processing models. This undermines the claim that a formal representational theory of mind is 'the only game in town.' In particular it suggests a radically different model of brain function and its relation to epistemology from that found in current representational theories. (shrink)

Abstract The phenomenology of Multiple Personality (MP) syndrome is used to derive an Aristotelian explanation of the failure to achieve rational integration of mental content. An MP subject is best understood as having failed to master the techniques of integrating conative and cognitive aspects of her mental life. This suggests that in irrationality the subject may lack similar skills basic to the proper articulation and use of mental content in belief formation and control of action. The view that emerges centres (...) mind on the activity of a subject rather than a structured causal nexus. (shrink)

The psychopathic personality disorder historically has been thought to include an insensitivity to morality. Some have thought that the psychopath's insensitivity indicates that he does not understand morality, but the relationship between the psychopath's defects and moral understanding has been unclear. We attempt to clarify this relationship, first by arguing that moral understanding is incomplete without concern for morality, and second, by showing that the psychopath demonstrates defects in frontal lobe activity which indicate impaired attention and adaptation to environmental conditions (...) which are relevant to the formation of complex intentions. We argue that these frontal lobe defects can help to explain both the psychopath's apparent insensitivity to morality and his characteristic imprudence. (shrink)
