Of the countless essays on the work of Friedrich Nietzsche, the complete overview by Karl Jaspers continues to stand out as a unique achievement. Nietzsche is presented as a 'great philosopher' in historical and systematically comprehensive terms. The expert opinion formulated by Jaspers, a psychiatrist, on Nietzsche's illness, which was based on all available medical data, remains of undiminished importance.
