In the nightmare world of The Trial and The Castle, only one thing is certain: that the central figure, significantly known by the initial K, is doomed to frustration. All else is dreamlike and unsure; courtrooms spring up in tenements, mysterious warders devour one’s breakfast, a man thought to be Sordini is actually Sortini. The central fact is certain, though: K will fail in his attempt to attain grace.
The two novels have the same theme and approximately the same basic structure. In both, K seeks for grace and is led to the final realization that it is to be withheld from him. (The Castle is unfinished, but its conclusion seems plain.) Kafka brings his heroes into involvement with their situations in opposite ways: in The Trial, Joseph K. is passive until he is jolted into the action of the book by the unexpected arrival of the two warders; in The Castle, K is first shown as an active character making efforts on his own behalf to reach the mysterious Castle. To be sure, though, he has originally been summoned by the Castle; the action did not originate in himself, and thus he began as as passive a character as Joseph K. The distinction is that The Trial opens at a point earlier in the time-stream of the action — at the earliest possible point, in fact. The Castle follows more closely the ancient rule of beginning in medias res, with K already summoned and trying to reach the Castle.
Both books get off to rapid starts. Joseph K. is arrested in the very first sentence of The Trial, and his counterpart K arrives at what he thinks is going to be the last stop before the Castle on the first page of that novel. From there, both K’s struggle futilely toward their goals (in The Castle, simply to get to the top of the hill; in The Trial, first to understand the nature of his guilt, and then, despairing of this, to achieve acquittal without understanding). Both actually get farther from their goals with each succeeding action. The Trial reaches its peak in the wonderful Cathedral scene, quite likely the most terrifying single sequence in any of Kafka’s work, in which K is given to realize that he is guilty and can never be acquitted; the chapter that follows, describing K’s execution, is little more than an anticlimactic appendage. The Castle, less complete than The Trial, lacks the counterpart of the Cathedral scene (perhaps Kafka was unable to devise one?) and thus is artistically less satisfying than the shorter, more intense, more tightly constructed Trial.
Despite their surface artlessness, both novels appear to be built on the fundamental threepart structure of the tragic rhythm, labeled by the critic Kenneth Burke as “purpose, passion, perception.” The Trial follows this scheme with greater success than does the incomplete Castle; the purpose, to achieve acquittal, is demonstrated through as harrowing a passion as any fictional hero has undergone. Finally, when Joseph K. has been reduced from his original defiant, self-confident attitude to a fearful, timid state of mind, and he is obviously ready to capitulate to the forces of the Court, the time is at hand for the final moment of perception.
The agent used to bring him to the scene of the climax is a classically Kafkaesque figure — the mysterious “Italian colleague who was on his first visit to the town and had influential connexions that made him important to the Bank.” The theme that runs through all of Kafka’s work, the impossibility of human communication, is repeated here: though Joseph has spent half the night studying Italian in preparation for the visit, and is half asleep in consequence, the stranger speaks an unknown southern dialect which Joseph cannot understand. Then — a crowning comic touch — the stranger shifts to French, but his French is just as difficult to follow, and his bushy mustache foils Joseph’s attempts at lip-reading.
Once he reaches the Cathedral, which he has been asked to show to the Italian (who, as we are not surprised to find, never keeps the date), the tension mounts. Joseph wanders through the building, which is empty, dark, cold, lit only by candles flickering far in the distance, while night inexplicably begins fast to fall outside. Then the priest calls to him, and relates the allegory of the Doorkeeper. It is only when the story is ended that we realize we did not at all understand it; far from being the simple tale it had originally seemed to be, it reveals itself as complex and difficult. Joseph and the priest discuss the story at great length, in the manner of a pair of rabbinical scholars disputing a point in the Talmud. Slowly its implications sink in, and we and Joseph see that the light streaming from the door to the Law will not be visible for him until it is too late.
