What if I were wounded and made crazy, what would happen if I were sent back to the front?" By separating himself from the characters he created, Hemingway strengthens the drama. The means of achieving a strong drama is to minimize, or omit, the feelings that produced the fiction he wrote. Hemingway's iceberg theory highlights the symbolic implications of art. He makes use of physical action to provide an interpretation of the nature of man's existence. It can be convincingly proved that, "while representing human life through fictional forms, he has consistently set man against the background of his world and universe to examine the human situation from various points of view." Wendolyn Tetlow believes that Hemingway's early fiction such as "Indian Camp" shows his lack of concern for character development by simply placing the character in his or her surroundings. However, in "Indian Camp" the use of descriptive detail such as a screaming woman, men smoking tobacco, and an infected wound build a sense of veracity. In other words, a story can communicate by subtext; for instance, Hemingway's "Hills Like White Elephants" does not mention the word "abortion", although in the story the male character seems to be attempting to convince his girlfriend to have an abortion. "Big Two-Hearted River", Hemingway explains, "is about a boy ... coming home from the war ... So the war, all mention of the war, anything about the war, is omitted." Hemingway intentionally left out something in "Indian Camp" and "Big Two-Hearted River"—two stories he considered to be good. Baker explains that Hemingway's stories about sports are often about the athletes themselves and that the sport is incidental to the story. Moreover, the story "A Clean Well Lighted Place" which on the surface is about nothing more than men drinking in a cafe late at night, is in fact about that which brings the men to the cafe to drink, and the reasons they seek light in the night—none of which is available in the surface of the plot, but lurks in the iceberg below. Hemingway's story "Big Two-Hearted River" is ostensibly about nothing, as is "A Clean Well Lighted Place", but within nothing lies the crux of the story. Hemingway scholar Jackson Benson further believes that the omission Hemingway applies functions as a sort of buffer between himself as the creator of a character and the character. He explains that as an author creates a "distance" between himself and the character he "becomes more practiced, it would seem."
