This is an exploration and reassessment of the philosophical notion of relation. In contrast to the scholastic, ontological conception of relationas a thing of diminished being, this book views relation as the minimal and elemental theme and structure of philosophy. Drawing radical conclusions from the classical understanding of relation as a being-toward-another, it argues that rethinking relation engages the very possibility and limits of philosophical discourse. In the author s studies of Nietzsche and Benjamin, Husserl and Heidegger, Derrida and Blanchot, relation is shown to be central to their thought and to undergo elaborations that escape the ontological, categorial, and formalist ways in which the concept has traditionally been interpreted. Comprehending relation in terms of determination, foundation, mediatization, translation, or communication, these authors are shown to draw out and refine a host of structural implications of the notion that unseat its formalist and categorial conception.
