A German critic has reproached me for my ignorance of Nietzsche’s works. I have read several of them, but the mixture of genius and madness in them makes them difficult to use. In this connection Moebius’ volume, _Ueber das Pathologische bei Nietzsche_ (Wiesbaden, 1902), is of interest. [174] Quoted by Oldenberg, _Le Bouddha_, French translation, Paris, 1894, p. 214.
