Book excerpt: In Quakers and Politics, Carl and Margery Post Abbott establish the theological roots of political activism among members of the Society of Friends. By profiling a number of representative individuals and describing the major institutions through which Quakers influence public policy, the Abbotts trace the history of Quaker activism and survey the political involvement of Quakers today. Quakers and Politics brings a special approach to political action that draws on 360 years of activism.
