Volume 26 presents three versions of the "Doctrine of Faith" lectures that Troeltsch held every two years as the Heidelberg Ordinarius for systematic theology. Alongside the lecture of 1911 (edited by Gertrud von le Fort in 1925), the volume also includes dictation notes for a lecture held in winter semester 1908/09 (transmitted in a transcript by Karl Barth). A lecture transcript from winter 1906/07 and summer 1908 is by an unknown student.
