This book brings together leading sociologists to challenge common notions that spirituality is individualistic, privatized, and apolitical - and to make the definitive case for its social and political significance. Contributors examine the sweeping influence of spirituality on a variety of realms, including health care and therapeutic practice, popular culture, civic engagement, public protest, conspiracy culture, and progressive politics. Leveraging cutting-edge quantitative and qualitative data, this authoritative book makes clear that, far from being marginal and inconsequential, spirituality holds profound public importance today.
