Pierre Keller examines Kant's theory of self-consciousness and argues that it succeeds in explaining how both subjective and objective experience are possible. He argues for a new understanding of Kant's conception of self-consciousness as the capacity to abstract not only from what one happens to be experiencing, but also from one's own personal identity. By developing this new interpretation he is able to argue that transcendental self-consciousness underwrites a general theory of objectivity and subjectivity at the same time.
