According to Beard the average life of 500 men of genius is 54, and that of 100 modern men of genius is 70. The average duration of life of 35 men of musical genius was 63 years, and 8 months.[147] But this fact does not exclude degeneration when, as among persons with moral insanity, it is united with an apathy which renders temperaments otherwise mobile, insensible to the strongest griefs, and I have shown in another book[148] that instinctive criminals, living out of prison, enjoy great longevity. It should be added that longevity is not always found in genius; many great men of genius, such as Raphael, Pascal, Burns, Keats, Byron, Mozart, Felix Mendelssohn, Bellini, Bichat, Pico de la Mirandola died before the age of forty. CHAPTER IV. GENIUS AND INSANITY. Resemblance between genius and insanity--Men and women of genius who have been insane--Montanus--Harrington--Haller--Schumann--Gérard de Nerval--Baudelaire--Concato--Mainländer--Comte--Codazzi--Bolyai--Cardan--Tasso--Swift--Newton--Rousseau--Lenau--Széchényi--Hoffmann--Foderà--Schopenhauer--Gogol. The resemblance between insanity and genius, although it does not show that these two should be confounded, proves at all events that one does not exclude the other in the same subject. In fact, without speaking of the numerous men of genius who at some period of their lives were subject to hallucinations or insanity, or of those who, like Vico, terminated a great career in dementia, how many great thinkers have shown themselves all their lives subject to monomania or hallucinations!
