“The great juggle for a festival organiser is not so much personal safety versus freedom of speech. It’s: What is your relationship with any government, because the act of writing is essentially dissident. That’s what distinguishes literature, and the public act of a literary festival, from buying a Guggenheim museum or a symphony orchestra: it’s not just something rich people do. It’s a place for extending the conversation, and you have to subscribe to the idea that people can contradict you.”
