In the Wall Street Journal, Ian Buruma writes about Google vs. China and the history of information control in China:
Thought control, in terms of imposing an official orthodoxy, is a very old tradition. The official glue that has long been applied to hold Chinese society together is a kind of state dogma, loosely known as Confucianism, which is moral as well as political, stressing obedience to authority. This is what officials like to call Chinese culture.
One can take a more cynical view, of course, and see culture as a mere fig leaf meant to hide the machinations of political power. The latest Chinese salvo against the U.S., blaming the Americans for instigating rebellion in Iran through the Internet, reveals that the current spat has a hard (and opportunistic) political core. And the assumption that Google, as a Chinese editorial put it, is a “political pawn” of the U.S. government, is a clear case of projection.
In any case, instilling the belief that obedience to authority is not just a way to keep order, but an essential part of being Chinese, is highly convenient for those who wield authority, whether they be fathers of a family or rulers of the state. That is why in their efforts to promote democracy after World War I, Chinese intellectuals denounced Confucianism, with its rigid social hierarchy, as an outmoded orthodoxy which had to be eradicated.
