The important observation to make about the narrative of Catch-22 is the centrality and tremendous gravity of trauma. A few ugly, awful, dehumanizing, bloody experiences dominate the narrative. They aren't always talked about directly, and in fact the novel spends a lot of time rather elaborately and obviously NOT talking about them, but it becomes obvious that these incidents are the dark stars around which those stories that do get explicitly told revolve.
Living ourselves in a slowly-emerging post-war era, we are more than a little familiar with stories of wartime trauma, how that kind of trauma can be excruciatingly hard to deal with, how often it results in dysfunction, abuse and suicide long after the incidents themselves have seemingly been put behind those that experienced them.
Catch-22 telling a story that both desperately wants to be told and desperately wants not to be recalled. Scenes like (especially) Snowden bleeding to death in the plane over Avignon and Kid Sampson being accidentally obliterated are for most of the book obliquely referred to touchstones, dark stars around which the explicit stories revolve.
In a way, Catch-22 is a wholly different response to Hemingway's "iceberg theory" and its inherent suspicion of words. Hemingway's suspicion of BIG words is, of course, almost definitional of his writing style and of his era. Many recall the famous passage in A Farewell to Arms to this effect:
I was always embarrassed by the words sacred, glorious, and sacrifice and the expression in vain. We had heard them, sometimes standing in the rain almost out of earshot, so that only the shouted words came through, and had read them, on proclamations, now for a long time, and I had seen nothing sacred, and the things that were glorious had no glory and the sacrifices were like the stockyards at Chicago if nothing was done with the meat except to bury it. There were many words that you could not stand to hear and finally only the names of places had dignity. Certain numbers were the same way and certain dates and these with the names of the places were all you could say and have them mean anything. Abstract words such as glory, honor,courage, or hallow were obscene beside the concrete names of villages, the numbers of roads, the names of rivers, the numbers of regiments and the dates.But it wasn't just big words that Hemingway and his protagonists distrusted. Hemingway cultivated a style that emphasized what it omitted:
If a writer of prose knows enough of what he is writing about he may omit things that he knows and the reader, if the writer is writing truly enough, will have a feeling of those things as strongly as though the writer had stated them. The dignity of movement of an ice-berg is due to only one-eighth of it being above water. (Source)That iceberg dignity is what Hemingway strove for. The central fact of Hemingway's life and times was the experience of World War I. That experience is also central for many of his protagonists. But many of his great war-related stories barely mention the war, and his protagonists seem to make it their business to drive thoughts of it out of their minds with mundane ritual.
It is easy to see Hemingway and his protagonists as suffering from what we'd call Post-Traumatic Stress Syndrome (PTSD). Hemingway's "Iceberg theory" can be seen as simply a rationalization of avoidance, the refusal to remember or be reminded of traumatic experiences, a classic PTSD symptom. But it is also a more philosophical expression of a mistrust of words, of explicitness, to express the truth about the seven-eighths beneath the surface. To attempt to bring those truths and traumatic experiences to the surface was, inevitably, to make them into lies.
As PTSD therapists often relate, words and narrative help veterans structure, normalize, and contextualize horrific experiences and allow them to move on with normal post-war lives. But for Hemingway PTSD might be said to represent a more appropriate, though highly impractical, response to horror.
Trying to talk directly about such experiences, while perhaps a practical necessity for those who have to remember them, is domesticating what can never be truly domesticated.
Hemingway's goals as a writer weren't to return to normalcy, it was to try to somehow speak truthfully of these experiences. Talking through these things meant going from avoidance to lying. That's the danger of words & stories: they can give a false sense of control and normality and acceptability to that which is not controlled, normal or acceptable.
But through implicitness, Hemingway thought he might be able to make the reader understand something true about the War. Heller, I'd argue, makes the same observation about the fundamental hostility between explicitness and the truth behind trauma, but responds to it with a radically different technique. Instead of the spare, economical prose from which the explicit has been merely excised, Heller chooses to give us vignette after vignette, in an order which is non-chronological and indirect but which allows us to gradually come nearer the truth until, finally, it is given to us.
Though he was quick to remark its apparent lack of form, Norman Mailer clearly recognized the technique behind Catch-22's structure. As Mailer read, he could perceive the narrative "building upon itself" and that the book eventually "becomes substantial." The result is that "Heller is carrying his reader on a more consistent voyage through Hell than any American writer before him . . ."(from "Some Children of the Goddess")
There is, of course, an oppressive air of manliness to Heller's and Hemingway's (and Mailer's) war stories, but war is NOT the only source of the "iceberg" kind of trauma. And war is not the only experience or institution which lends itself to this sort of agglomerative story-telling. Another is the family.
In fact, this sort of storytelling is common wherever we gravely doubt the ability of telling to convey an experience or situation, or where we doubt the reader/listener's ability to perceive or properly appreciate the experience behind the words. When children try to tease out family secrets or stories they are not yet old enough to hear, they are often merely told lies, or to shut up. But sometimes we are told true stories. Stories that give us a bit of what they "deserve to know." Stories that obliquely approach what they definitely aren't to know while, ultimately, avoiding them . . . and over time they may hear a lot of these. The sanitized story of why Uncle Paul was in prison. The story of how your grandmother went senile quite early. The story of how Uncle Paul was able to fix things when you were in a jam. The story of your aunts on the reservation in Oklahoma. The story of your bad brother. And so on . . . and over time a much broader picture emerges of a family with certain challengers and certain ways of responding, all of which you were to be shielded from as a child.
These family stories sometimes have some ultimate deep dark secret, some particular bit of forbidden knowledge, but more usually they are just stories of how hard, unjust life can be and how compromised it makes us. Truths most of us would like children to find out only in due time, after having heard and considered and absorbed and, yes, laughed at a host of tangential stories.
Heller mimics this sort of agglomerative storytelling. A storytelling that does not have a chronological order, but which does have important points of reference, only gradually and eventually revealed, which gives structure to the whole.
The narrative style is NOT merely arbitrary. And it is not just authorial whimsy (as, I fear, much of Middlesex is mere whimsy). Heller is taking a story-telling technique straight from the tellers of war stories, as he told one writer regarding the genesis of Catch-22:
"conversations with two friends . . . influenced me. Each of them had been wounded in the war, one of them very seriously. . . .The first one told some very funny stories about his war experiences, but the second one was unable to understand how any humor could be associated with the horror of war. They didn't know each other and I tried to explain the first one's point of vie to the second. He recognized that there had been lots of graveyard humor, but he could not reconcile it with what he had seen of war. It was after that discussion that the opening of Catch-22 and many incidents in it came to me."
(From Just One Catch: A Biography of Joseph Heller, by Tracy Dougherty, p 175)
Clearly Heller saw more to the war stories of the first man than "graveyard humor." He appreciates the gravity with which the second man considers his experience, but he saw humorous anecdotes as a legitimate way of approaching, slowly and indirectly, the experience of war. The motive in such storytelling is not so much to protect the reader from the truth, but to protect the truth for the reader.
This approach is not only commonplace in oral storytelling. Many, many mysteries, for instance, are built on the story of a young person's building a deeper, secret, usually familial story, one seemingly random anecdote or fact at a time. In the end the last piece of the puzzle, the centerpiece, reveals the significance of all.
There is a center to Catch-22, or perhaps "are centers" around which the oblique narratives are organized. The trauma of Snowden's slow death and Yossarian's helplessness before it is an obvious one. But the effect isn't one of "all is revealed." It's a lot more subtle, and far more true to life.
