On the one hand you have a discourse of experts - critics, competition juries etc - who have the authority to decide what is eccentric and what is not. In a way like a doctor has the power to decide what is mad and what is sane.
And on the other hand you have the public, who have some sort of memory of a time when eccentricity was allied to genius, like when mad people were thought to be blessed with divine grace.
This is a really interesting tension. We don’t know whether to listen to Pogorelich, to take him seriously, or not.
