Existential gratitude-gratitude for one's very existence or life as a whole-is pervasive across the most influential human, cultural and religious traditions. Weaving together analytic and continental, as well as non-western and historical philosophical perspectives, this volume explores the nexus of gratitude, existence and God as an inter-subjective phenomenon for the first time. A team of leading scholars introduce existential gratitude as a perennially and characteristically human phenomenon, central to the distinctive life of our species. Attention is given to the conditions under which existence itself might be construed as having a gift-like or otherwise gratitude-inducing character. Drawing on a diversity of perspectives, chapters mark out new territory in philosophical inquiry, addressing whether and in what sense we ought to be grateful for our very existence. By analysing gratitude, this collection makes a novel contribution to the discourse on moral emotions, phenomenology, anti-natalism and theology. This rich collection of essays addresses an important and wide-spread phenomenon: existential gratitude. This phenomenon has not been sufficiently explored by philosophers, so this volume is timely. The contributors discuss existential gratitude by engaging with a wide array of philosophical traditions, periods, perspectives, and thinkers.
