Book excerpt: This distinctive and contemporary departure from hackneyed discussions of political theory introduces readers to a contemporary personalism rooted in the work of Bartolome de Las Casas and emerging again in the contributions of Dorothy Day, Peter Maurin as well as the liberation theology of Gustavo Guiterrez and Jon Sobrino. Thomas R. Rourke and Rosita A. Chazarreta Rourke introduce readers to new sources of personalism by investigating and revising the intellectual history of this theory and its development.
