With interest in Karl Barth running at unprecedented levels in the English-speaking world, this is a new edition of his survey-volume of formative eighteenth and nineteenth-century thinkers. With a comprehensive and extensive new introduction, in which the volume is re-contextualized and re-introduced for a fresh generation, this work can be used as a set text for courses in the history of Christian thought and doctrine as well as supplementary reading for students of continental intellectual history. All the most significant figures are here, in addition to several lesser-know thinkers. The translations of Barth's major essay "On the Task of a History of Modern Protestant Theology" and his original German preface of 1946 are also included.
