Mozart at play: the limitations of attributing the etiology of genius to tourette syndrome and mental illness.

There has been a persistent attempt to explain Mozart's talent as connected to physical and mental illness. While Mozart's musical compositions and performances were often acclaimed for their "taste," the composer's personal behavior sometimes astonished those who witnessed "blödeln" or wild horseplay, practical joking, and scatological humor. Most recently, Mozart's eccentric behavior has been attributed to Gilles de la Tourette syndrome. This chapter investigates the evidence for these retrospective diagnoses and reassesses this evidence by paying particular attention to the milieu in which Mozart lived. We argue that Mozart's putative pathological behavior was a manifestation of his resilience in face of multiple adversities and was deeply rooted in his sense of play. Our hypothesis is that play, rather than neuropsychiatric disease, was essential to the operation of his genius.
