An excerpt from an interview
http://www.conjunctions.com/archives/c17-ca.htm with Chinua Achebe who gets Man International Booker award this year.
"My instinct is to talk about politics in my work and that is your instinct too. That is the sense in which Come Sunday, too, is a very powerful story. An effective, powerful and moving depiction of the modern world with its politics in all its various dimensions. One should not attempt to avoid that because of this superstition that politics somehow is inimical to art. There are some who cannot manage politics in their fiction, so let them not . But they must not insist that everybody else must avoid politics because of some superstition built up in recent times that defines art as only personal, introspective, away from the public arena. That's nonsense. Fiction in the West has suffered in recent times by that limitation. When I see a book like yours which is grappling with the big issues -- violence, injustice, victimization -- that also has the scope of the whole world, that goes from the center to the periphery and back, that's great. It's difficult to do, but difficulty is no reason not to do it."
"The emperor would prefer the poet to keep away from politics, the emperor's domain, so that he can manage things the way he likes. When the poet is pleased to do that, the emperor is happy and will pay him money to stay within his aesthetic domain. But you and I don't have to agree with the emperor. We have to say no. Our business involves the peace, happiness and harmony of not just people but the planet itself, the environment. How we live in the world is extremely important. How we see our relationship with the environment is important. If we see it in terms of conquest, if we go out and conquer Mount Everest, what are we doing? Even the language becomes significant. If somebody climbs a mountain, they conquer it"
