Sue Prideaux’s biography tells a familiar story. Born into a religious family, Friedrich Nietzsche is a brilliant young student of philology, not philosophy, and soon becomes a professor in Basel, bewitched by Schopenhauer’s philosophy and by Wagner’s music, personality and wife. He breaks with Wagner to commence a nomadic life, especially in the Mediterranean and the Alps, funded by a generous pension (this is one of the few stories you are likely to read in which the most humane, generous and open-minded character is the university administration). Nietzsche is a gentle, troubled genius, unlucky in love, plagued by miserable health, whose mild personality contrasts dramatically with his bombastic prose. He goes mad in 1889 and dies in 1900, at which point the evil sister, Elisabeth, seizes control of his literary estate and aids in his disastrous misappropriation by the Nazis. The apolitical, individualistic and cautious philosophy of a man who hated anti-Semites and German nationalists is converted, tragically, into frothing, war-hungry, racist brutality – an error the storyteller seeks to correct. Prideaux’s biography ends in the gardens of the Weimar villa in which Nietzsche died, from where the modern visitor can gaze down to the chimney of Buchenwald concentration camp. The message is clear: Elisabeth invites the Nazis round to dance on Nietzsche’s grave, while he meekly turns within it.
