translation, which appeared twenty or more years ago) Degeneration; in a chapter devoted to Nietzsche it was stated that his works had been written between periods of residence in a madhouse. The legend dies hard and lingers on faintly in the latest writers who have not made any real study of the case. The fact is, that the insanity came, as just indicated, suddenly, almost without warning, for his latest writings are some of his most lucid—and that nothing was produced by him afterward, save a few incoherent notes and letters, written or scrawled in the first days of his dementia. That there are any anticipations of the catastrophe (i.e., signs of incipient dementia) in his books is at best a subjective opinion—indeed it is a view which tends to be abandoned more and more.f Highly wrought Nietzsche often was, particularly in his latest writings; he said extravagant things and uttered violent judgments. So did Carlyle; so have many earnest, lonely men, struggling unequally with their time; but insanity is another matter.
The causes of his collapse were probably manifold. A few circumstances may be mentioned which may have co-operated to produce the result. Nietzsche himself mentions a decadent inheritance which he had from his father, though he thought it counterbalanced by a robust one from his mother.[1] While serving his time in the Prussian artillery, he suffered a grave rupture of muscles of the chest in mounting a restive horse, and for a time his life was in danger. During the Franco-Prussian war, the illnesses already mentioned were aggravated by strong medicines that seem to have permanently deranged his digestion; in any case, sick-headaches of an intense and often prolonged character became frequent. He had serious eye-troubles (he was always nearsighted), and became almost blind late in life. Strain of this and every kind produced insomnia—and this in turn led to the use of drugs, and of stronger and stronger ones. All the time he was leading the intensest intellectual life. Whether such a combination of causes was sufficient to produce the result, medical experts must judge. Nietzsche himself once remarked, "We all die too young from a thousand mistakes and ignorances as to how to act."[2]
