"Nobody these days holds the written word in such high esteem as police states do," Arkadian Porphyrich says. "What statistic allows one to identify the nations where literature enjoys true consideration better than the sums appropriated for controlling it and suppressing it? Where it is the object of such attentions, literature gains an extraordinary authority, inconceivable in countries where it is allowed to vegetate as an innocuous pastime, without risks. To be sure, repression must also allow an occasional breathing space, must close an eye every now and then, alternate indulgence with abuse, with a certain unpredictability in its caprices; otherwise, if nothing more remains to be repressed, the whole system rusts and wears down. Let's be frank: every regime, even the most authoritarian, survives in a situation of unstable equilibrium, whereby it needs to justify constantly the existence of its repressive apparatus, therefore of something to repress."
