There are some serious limitations in Mo Yan's situation as a writer in China today - just as there are for Jia Zhangke, one of the world's greatest film directors. He can only phrase his dissent obliquely, in his art. Writers in "free" societies labor under no such constraints. They can write more or less whatever they want in both their fiction and their commentary. Yet so many of them look oddly inhibited, even timid, and depressingly a couple of prominent figures actually positioned themselves to the right of their governments, intelligence agencies, and corporations.
I think a more complex idea of fiction - and the human self's relationship with the world - emerges when we abandon this philistine equation between literature and liberalism and human goodness, and pay some attention to the darker, ambiguous, and often muddled energies and motivations that shape a work of art. If we do this, we can appreciate a writer like CĂ©line or Gottfried Benn without worrying whether they conform to existing notions of political incorrectness.
Writers in the nineteenth century - people like George Eliot and Flaubert - were accustomed to addressing particular communities with which they shared not only linguistic meanings but also an experience and history. Those communities have progressively split in the twentieth century, and grown more heterogeneous, and writers emerging from minority communities have found themselves addressing audiences closer to their experience and history - a phenomenon derided by conservative white men as identity politics and multiculturalism in the arts.
The recent past is full of diverse examples of writers - Mahfouz in Egypt, Pamuk in Turkey, and more interestingly, Pasternak in the Soviet Union - who have conducted their arguments with their societies and its political arrangements through their art in subtle, oblique ways. They didn't always have the license to make bold pronouncements about freedom, democracy, Islam, and liberalism, but they exerted another kind of moral authority through their work.
