There was great political uncertainty in South Asia at the time of the Buddha. The older small tribal societies were cracking up and gave way to bigger states. There was much more trade and travel going on than before. To people in the cities the experience of living in a small place where you knew everyone and governed your affairs by consensual democracy had been lost.

So much of writing is fed by vanity and the feeling that what you are doing is the most important thing in the world and it has not been done before and only you can do it. Without these feelings, many writers would not be able to write anything at all.

In the end, of course, all novelists will be judged by their novels, but let's not forget that we will also need new ways of assessing the latter.

In the modern world, nationalism remains a very important force. We delude ourselves into thinking that globalization has made all of that redundant and that everyone just wants to be like America.

I don't think of myself as particularly earnest. I have long bouts of cynicism and skepticism. So much of my early life was full of uncertainties. It still is. My "Buddha book" expresses that. Perhaps that's what created this impression of earnestness.

A sustained engagement with the world, a sense of how it was and how it ought to be, and what has been lost, is imperative to good writing - I just don't know how you can be a serious writer without it.

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.
