If Richelieu had not on one single occasion been caught in an epileptic fit, who could ever have guessed it? If it had not been for the recent works of Berti and Mayor, who would have believed that Cavour twice attempted to kill himself? If Taine had not been one of those rare writers who understand what help psychiatry can give in the study of history, he would never have been able to surprise those characteristics which make Napoleon's moral insanity manifest to all. Carlyle's wife wrote the narration of her tortures; few wives do as much, and, to tell the truth, few husbands are anxious to publish such narratives. Many persons still regard as an angelic being the celebrated painter Aiwosowski, who succoured hundreds of poor persons and left his own wife and children to die of hunger.
It must be added that moral insanity and epilepsy which are so often found in association with genius arc among the forms of mental alienation which are most difficult to verify, so that they are often denied, even during life, although quite evident to the alienist. There are still many estimable persons who doubt the insanity of King Ludwig of Bavaria, and even openly deny it.[1]
There are, also, no individual cases in nature; all particular cases are the expression and effect of a law. And the fact, now unquestioned, that certain great men of genius have been insane, permits us to presume the existence of a lesser degree of psychosis in other men of genius.
But, adds Joly, genius is often precocious; as Raphael at fourteen years of age, Mozart at six, Michelangelo at sixteen; and sometimes it is tardy, with special characteristics, as in Alfieri. This is true; precocious originality is one of the characteristics of genius; but precisely because genius is a neurosis, an accidental circumstance may provoke it even at a comparatively late age, and like every neurosis which depends on irritation of the cerebral cortex it may take on different aspects, according to the spot attacked, while preserving the same nature.
