Book excerpt: Love, Reason, and Will: Kierkegaard After Frankfurt introduces and investigates themes common to Harry G. Frankfurt and Søren Kierkegaard, focusing particularly on their understanding of love. Several distinguished contributors argue that Kierkegaard's insights about love, volition, and identity can help us to evaluate aspects of Frankfurt's well-known arguments about love and caring; similarly, Frankfurt's analyses of the higher-order will, valuing, and self-love help clarify themes in Kierkegaard's Works of Love and other books. By bringing these two key thinkers into conversation with each other, we may glean a new understanding of the structure of love, reasons for love or deriving from loving, and more broadly, the central ethical questions of "how to live" and to develop an authentic identity and meaningful life. Love, Reason, and Will will appeal to readers interested in the philosophy of action and emotions, continental thought (especially in the existential tradition), the study of character in psychology, and theological work on neighbor-love and virtues.
