Book excerpt: An examination of the philosophical notion of sacrifice from Kant to Nietzsche. In this book, Paolo Diego Bubbio offers an alternative to standard philosophical accounts of the notion of sacrifice, which generally begin with the hermeneutic and postmodern traditions of the twentieth century, starting instead with the post-Kantian tradition of the nineteenth century. He restructures the historical development of the concept of sacrifice through a study of Kant, Solger, Hegel, Kierkegaard, and Nietzsche, and shows how each is indebted to Kant and has more in common with him than is generally acknowledged. Bubbio argues that although Kant sought to free philosophical thought from religious foundations, he did not thereby render the role of religious claims philosophically useless. This makes it possible to consider sacrifice as a regulative and symbolic notion, and leads to an unorthodox idea of sacrifice: not the destruction of something for the sake of something else, but rather a kenotic emptying, conceived as a withdrawal or a “making room” for others.
