Book excerpt: A valuable resource for anthropologists, ethnohistorians, and western historians who wish to better understand ritual life in the Plains region. —Western Historical Quarterly "Harrod's discussion of kinship and reciprocity in Northwest Plains cosmology contains valuable insight into Native American worldview, and his emphasis on the moral dimension of ritual process is a major addition to the too-often ignored subject of Native American moral life." —Journal of Religion "Includes the major works on Blackfoot, Crow, Cheyennes, and Arapaho religion, the works to which anyone who wishes to understand the religious life of these tribes must continue to turn." —Choice "Plains people, Harrod suggests, refracted nature and conceived an environmental ethic through a metaphor of kinship. He is particularly skillful in characterizing the ambiguity Plains people expressed at the necessity of killing and eating their animal kin. Renewing the World also contributes to another new and uncultivated science we might call 'ecology of mind'." —Great Plains Quarterly
