 As Nietzsche continued his residence in Switzerland between 1872 and 1879, he often visited Wagner at his new (1872) home in Bayreuth, Germany. In 1873, he met Paul Rée (1849–1901), who, while living in close company with Nietzsche in Sorrento during the autumn of 1876, would write On the Origin of Moral Feelings (1877). During this time, Nietzsche completed a series of four studies on contemporary German culture—the Unfashionable Observations (1873–76)—which focus respectively upon (1) the historian of religion and culture critic, David Strauss, (2) issues concerning the social value of historiography, (3) Arthur Schopenhauer and (4) Richard Wagner, both as heroic inspirations for new cultural standards.
