Symbols are objects, characters, figures, and colors used to represent abstract ideas or concepts.
As the source of the book’s title, this symbol merits close inspection. It first appears in Chapter 16, when a kid Holden admires for walking in the street rather than on the sidewalk is singing the Robert Burns song “Comin’ Thro’ the Rye.” In Chapter 22, when Phoebe asks Holden what he wants to do with his life, he replies with his image, from the song, of a “catcher in the rye.” Holden imagines a field of rye perched high on a cliff, full of children romping and playing. He says he would like to protect the children from falling off the edge of the cliff by “catching” them if they were on the verge of tumbling over. As Phoebe points out, Holden has misheard the lyric. He thinks the line is “If a body catch a body comin’ through the rye,” but the actual lyric is “If a body meet a body, coming through the rye.”
The song “Comin’ Thro’ the Rye” asks if it is wrong for two people to have a romantic encounter out in the fields, away from the public eye, even if they don’t plan to have a commitment to one another. It is highly ironic that the word “meet” refers to an encounter that leads to recreational sex, because the word that Holden substitutes—“catch”—takes on the exact opposite meaning in his mind. Holden wants to catch children before they fall out of innocence into knowledge of the adult world, including knowledge of sex.
The red hunting hat is one of the most recognizable symbols from twentieth-century American literature. It is inseparable from our image of Holden, with good reason: it is a symbol of his uniqueness and individuality. The hat is outlandish, and it shows that Holden desires to be different from everyone around him. At the same time, he is very self-conscious about the hat—he always mentions when he is wearing it, and he often doesn’t wear it if he is going to be around people he knows. The presence of the hat, therefore, mirrors the central conflict in the book: Holden’s need for isolation versus his need for companionship.
It is worth noting that the hat’s color, red, is the same as that of Allie’s and Phoebe’s hair. Perhaps Holden associates it with the innocence and purity he believes these characters represent and wears it as a way to connect to them. He never explicitly comments on the hat’s significance other than to mention its unusual appearance.
Holden tells us the symbolic meaning of the museum’s displays: they appeal to him because they are frozen and unchanging. He also mentions that he is troubled by the fact that he has changed every time he returns to them. The museum represents the world Holden wishes he could live in: it’s the world of his “catcher in the rye” fantasy, a world where nothing ever changes, where everything is simple, understandable, and infinite. Holden is terrified by the unpredictable challenges of the world—he hates conflict, he is confused by Allie’s senseless death, and he fears interaction with other people.
Holden’s curiosity about where the ducks go during the winter reveals a genuine, more youthful side to his character. For most of the book, he sounds like a grumpy old man who is angry at the world, but his search for the ducks represents the curiosity of youth and a joyful willingness to encounter the mysteries of the world. It is a memorable moment, because Holden clearly lacks such willingness in other aspects of his life.
