It is not only such obvious means of intimidation as machine guns and concentration camps that count; such a petty product of the printing press as an identity card, by making it easy for the authorities to keep constant watch on everybody's movements, represents in the long run a more effective curb on liberty. In Tibet, for instance, the introduction of such a system by the Chinese Communists, following the abortive rising of 1959,and its application to food rationing has been one of the principal means of keeping the whole population in subjection and compelling them to do the work decreed by their foreign overlords.
