Filling a gap in scholarship on 19th- and 20th-century religious thought, this book discusses the philosophy and theology of the influential Marburg School in Germany before 1914, focusing on the writings of Hermann Cohen, its leader, and on the Ritschlian theologian Wilhelm Herrmann, Karl Barth's teacher. In addition, Fisher examines Barth's earliest writings and clarifies the little-known liberal phase of Barth's theology.
