"There is a parable of Kafka’s about a man living in a country where he doesn’t know the rules. Nobody will tell him what they are. He knows neither right nor wrong, but he observes that the rulers do not share his anxiety. From this he deduces that rules are for those who rule. What they do is the rule. That’s why all my knowledge doesn’t make me understand what Mozart did that I should also do in order to reach a state of artistic grace"
