The"law issue"is an important theme in Kafka’s writings

which is closely related to his work on the Workers’Accident Insurance Institute. Kafka introduces and interprets the topics of risk and insurance in his daily office life into his literary creation. His novel Amerika explores the risk management in the"New World" of America

and the baffling arrest in The Trial implies problems of juridical fault and the assimilation of individual right into public right. The castle authority in The Castle is just like insurance in modern society as getting authority’s appointment means getting full assurance while being excluded from the society means the loss of security and economic guarantee. This is the very reason why Kafka appeals to extend the coverage of insurance.
