This is the second volume of the series ""Makers of Modern Theology"" published under the general editorship of Jaroslav Pelikan. The subject of the present work is Albrecht Ritschl; yet, it is neither a work of biography nor a synthesis of Ritschl's contribution, but rather an essay in theological methodology which constitutes, in effect, a critical study of Ritschlian theology. The work may be divided into two basic parts; first, an analysis of Ritschl's methodology; second, a discussion of the issues that Ritschl's work raises concerning the interweavings of history and life, with an analysis of their implications and an indication of other factors that must be taken into account if such issues are to be dealt with adequately. From Dr. Hefner's approach and treatment, it is evident that he intends his work for a specialist audience; that audience, however, is not limited to the theologian, but should include the historian, the student of scientific methodology, and the discriminating general reader with an interest in the intellectual history of man. Within those limits, Faith and the Vitalities of History may be recommended as a work of extraordinary insight and synthetic power.
