In both these short volumes, Ruth Lane assumes an optimis- tic stance, generally within the mainstream of political sci- ence, and attempts to synthesize past and present trends in an effort to show progress. She argues in The Art of Comparative Politics that, despite the disparate approaches, real advances have occurred within the field. Her interpretative essay focuses on the recent history of the field, with an assessment of the behavioral movement during the 1960s and subsequent emphases on development, state, grassroots and peasant politics, and the new institutionalism. In Political Science in Theory and Practice she affirms that a core consensus has appeared in the independent investigations of prominent political scientists. Thus, a coherent working model of polit- ical behavior guides political scientists to understand political realities. She argues that this concrete model coincides with scientific realism and the current understanding of a philos- ophy of science.
