The correspondence between Luise Rinser and Hermann Hesse offers a unique insight into the thoughts of two outstanding writers of the 20th century. This collection includes not only the correspondence between the two authors, which spans from 1935 to 1951, but also two significant essays by Rinser about Hesse. The first essay, "Hermann Hesse," dates back to 1947 and sheds light on Hesse's literary work. The second, "Hermann Hesse and Eastern Philosophy," is an extensive lecture from 1978 that addresses Hesse's engagement with Eastern philosophical traditions. The correspondence is introduced by Rüdiger Haas, a recognized Hesse expert, who explains the context and significance of these letters. This publication is of interest not only to Hesse enthusiasts but also to anyone interested in the literary connections and exchanges between prominent figures in literary history.
