The world is confronted with multiple intersecting crises including exploitation, inequality, political polarization and climate change. World-repairing work is vitally needed. But just at a time when humans most obviously require robust moral imaginaries on which to draw, it is no longer clear what kinds of beliefs, meanings, stories and encounters inspire them to act. We know that nonreligious identities are on the rise in numerous countries throughout the world. But with so much focus on the "non" part of nonreligion, what we don't know is what nonreligious imaginaries actually look, sound and feel like. What do nonreligious people believe in? What stories inspire them? In what moments do they find meaning? This book seeks to answer these questions through a series of short essays exploring the nonreligious imaginaries that emerge in a range of world-repairing practices, including ethical consumption, community organizing, eating habits, and environmental activism. In so doing, the book provides a crucial contribution to two areas of increasing social and political concern: First, the need to understand not only what nonreligious people are rejecting but also their sources of meaning and action. Second, the urgent need for cultural tools for mobilizing people towards more compassionate and sustainable practices.
