Structurally the novel is over right here. Joseph has received the final perception that acquittal is impossible; his guilt is established, and he is not yet to receive grace. His quest is ended. The final element of the tragic rhythm, the perception that ends the passion, has been reached.
We know that Kafka planned further chapters showing the progress of Joseph’s trial through various later stages, ending in his execution. Kafka’s biographer Max Brod says the book could have been prolonged infinitely. This is true, of course; it is inherent in the nature of Joseph K.’s guilt that he could never get to the highest Court, just as the other K could wander for all time without ever reaching the Castle. But structurally the novel ends in the Cathedral; the rest of what Kafka intended would not have added anything essential to Joseph’s self-knowledge. The Cathedral scene shows us what we have known since page one: that there is no acquittal. The action concludes with that perception.
The Castle, a much longer and more loosely constructed book, lacks the power of The Trial. It rambles. The passion of K is much less clearly defined, and K is a less consistent character, not as interesting psychologically as he is in The Trial. Whereas in the earlier book he takes active charge of his case as soon as he realizes his danger, in The Castle he quickly becomes the victim of the bureaucracy. The transit of character in The Trial is from early passivity to activity back to passive resignation after the epiphany in the Cathedral. In The Castle K undergoes no such clearcut changes; he is an active character as the novel opens, but soon is lost in the nightmare maze of the village below the Castle, and sinks deeper and deeper into degradation. Joseph K. is almost an heroic character, while K of The Castle is merely a pathetic one.
The two books represent varying attempts at telling the same story, that of the existentially disengaged man who is suddenly involved in a situation from which there is no escape, and who, after making attempts to achieve the grace that will release him from his predicament, succumbs. As they exist today, The Trial is unquestionably the greater artistic success, firmly constructed and at all times under the author’s technical control. The Castle, or rather the fragment of it we have, is potentially the greater novel, however. Everything that was in The Trial would have been in The Castle, and a great deal more. But, one feels, Kafka abandoned work on The Castle because he saw he lacked the resources to carry it through. He could not handle the world of the Castle, with its sweeping background of Brueghelesque country life, with the same assurance as he did the urban world of The Trial. And there is a lack of urgency in The Castle; we are never too concerned over K’s doom because it is inevitable; Joseph K., though, is fighting more tangible forces, and until the end we have the illusion that victory is possible for him. The Castle, also, is too ponderous. Like a Mahler symphony, it collapses of its own weight. One wonders if Kafka had in mind some structure enabling him to end The Castle. Perhaps he never intended to close the novel at all, but meant to have K wander in ever-widening circles, never arriving at the tragic perception that he can never reach the Castle. Perhaps this is the reason for the comparative formlessness of the later work: Kafka’s discovery that the true tragedy of K, his archetypical hero-as-victim figure, lies not in his final perception of the impossibility of attaining grace, but in the fact that he will never reach even as much as that final perception. Here we have the tragic rhythm, a structure found throughout literature, truncated to depict more pointedly the contemporary human condition — a condition so abhorrent to Kafka. Joseph K., who actually reaches a form of grace, thereby attains true tragic stature; K, who simply sinks lower and lower, might symbolize for Kafka the contemporary individual, so crushed by the general tragedy of the times that he is incapable of any tragedy on an individual level. K is a pathetic figure, Joseph K. a tragic one. Joseph K. is a more interesting character, but perhaps it was K whom Kafka understood more deeply. And for K’s story no ending is possible, perhaps, save the pointless one of death.
