I Feel Therefore I Am: The Biology of Emotion
A New Paradigm for Consciousness
About the Lecture
A novel hypothesis on the nature of mind will be presented and evaluated in the light of current data from neurobiology, psychology, and cognitive science. Emotion is described as foundational for consciousness, desires, and beliefs. Cognition is simply the further elaboration of the expressions of those desires and beliefs. Unconscious mental states are defined in terms of accessibility to potential or actual conscious states. In this theory, subjectivity is always prior to objectivity, i.e., "view from nowhere" types of accounts cannot develop without the prior emotional substrate of subjective states. The neurobiological mechanism for such a system will be outlined. The asymmetry between spatial and temporal experience of consciousness and the role of society (other minds) in the structure of consciousness will be briefly discussed if time permits. Implications of this paradigm will be discussed with reference to normal and abnormal human behavior, as well as for the current attempts to model the mind in the fields of artificial intelligence, neural networks, computational neuroscience, and claims made for the future capacities of mobile robots.
