The aim of this volume is twofold. First, it chronicles the most significant moments in this concept's long and remarkable evolutionary life, ranging from ancient Hebrew and Greek and Christian conceptions of love to those advanced by thinkers from Kierkegaard and Nietzsche and Levinas. Second, in addition to profiling these discrete historical moments, this volume also aims to tell an interconnected story, such that those who read it cover-to-cover might be able to walk away with a sense of the larger arc of its historical evolution, and specifically the ways in which love's horizons shifted from the transcendent to the immanent over the course of its history. Like other volumes in the series, the book is interspersed with short reflection chapters that touch on an array of people and subjects including Martin Luther King, Jr., Gian Lorenzo Bernini, and Platonic love poetry, which supplement the work's philosophical discussions.
