Book excerpt: This is a study of the concept of hope in the work of Kierkegaard, a subject whose significance has not been given enough scholarly attention, and which should not be treated simply by reference to other philosophical ideas, or merely as the antithesis of despair. An essential role of faith is to secure the ground for hope, and in this way faith secures the ground for the self. In short, authentic hope is not merely a fringe element, but is essential to Kierkegaard's project of the self.
