"The impersonality of the communist state is not easy to understand. The huge dangers with which its subjects are daily confronted seem to come from nowhere, while threatening everyone who accepts responsibility for his own existence and so dares to be a man. Franz Kafka described the workings of this machine in a prophetic book, the moral of which many of our statesmen, including Mr Powell, have yet to learn. When they have learnt it, they will also know why The Castle, along with every other work by Prague's greatest writer, is now banned in the country of his birth."
