Is there an internal relationship between consciousness and intentionality? Can mental content be described in such a way so as to avoid dualism? What is the influence of social context upon consciousness, conceptions of self and mental content? This book considers questions such as these and argues for a conception of consciousness, mental content and intentionality that is anti-Cartesian in its major tenets. Focusing upon the rule governed nature of concepts and the grounding of the rules for concept use in the practical world, intentional consciousness emerges as a phenomena that depends upon social context. Given that dependence, the authors consider and set aside attempts to reduce human consciousness and intentionality to phenomena explicable at biological or neuroscientific levels. (Series A)
