Abstract

The correspondence between the phenomenologist Ludwig Klages (1872–1956) and the Jewish neurologist and psychoanalyst Friedrich S. Rothschild (1899–1995) spanned the Weimar Republic, the Nazi era and the 1950s and relates to a field in which the natural sciences, neurology and the humanities overlap. It is novel because no correspondence by Klages has been published before and because it reaches back to places of the production of knowledge that were not known or had been forgotten, to innovations that philosophically and probably neurologically may still be relevant. In their context, the letters reveal the not inconsiderable extent to which Klages' anti-Semitism had an impact on his work as a whole.
