From the first line of the novel, The Sound and the Fury provides a conflicted perspective on boundaries (physical, metaphorical, linguistic, and otherwise). Benjy, a character defined by his inability to communicate, simultaneously operates as a witness to events, represented in his own relationship to the physical geography of the house. Benjy “cant get out” from the fence (Faulkner 52). He is bound by and connected to it, not only physically, but perhaps even metaphorically and temporally. For example, when a group of people passes along the fence, he “tried to say, but they went on, and I went along the fence, trying to say […] I held to the fence, looking after them and trying to say” (52). The fence marks the bounds of Benjy’s ability to connect with others, but he navigates it as much he can, first by following along the line of the boundary before finally clinging to it in his failed attempt to connect. It also represents a particular site of remembrance for him in that it is the place where Caddy has previously left and appeared. As T.P. tells, “He think if he down to the gate, Miss Caddy come back” (51). Limited though he is in this respect, the first line of the novel reveals his means of working around the limitation. It is “through the fence, between the curling flower spaces” that he is able to observe (3, emphasis mine). Much like his role within the family saga, Benjy, constrained by his own limitations of language and understanding, is still able to watch and witness, and even to relate events to the reader, in his own way.
Unlike Benjy, Quentin is resolute in his respect of boundaries, and seems to be defined by them. His attendance at Harvard hinges upon the fragmentation and sale of family land. His relationship to time is marked by a desire to recognize each passing moment, to the point where unity is wholly disintegrated. He witnesses its passage not only in “the shadow” sunlight casts or in hearing time pass, but also in his own thoughts, “counting to sixty and folding down one finger and thinking of the other fourteen fingers waiting to be folded down” (88). This isn’t limited to time, but rather, informs of Quentin’s overall view and experience of the world. For example, in his perception of the races, he views “a nigger […] [as] a sort of obverse reflection of the white people he lives among” (86). His view of them is not just of their inferiority, but rather of their imperfect opposition—lesser reflections of something higher. Notably, in a conversational fragment, Quentin associates Caddy with them, asking her, “Why must you do like nigger women do in the pasture the ditches the dark woods hot hidden furious in the dark woods” (92). There is an implication of racial muddying in his accusation, one associated with the transversal of a boundary, moving from the safe site of the house to the “dark woods,” from white to its “obverse reflection.” Perhaps he views Caddy’s soiling not just in terms of the impurity of sexuality and womanhood, but also, in some way, as a loss of racial purity as well (maybe due to her large number of sexual partners, and her inability to positively identify her child’s father?).
Unlike her brothers, it is Caddy who straddles and crosses boundaries (in both directions). It is not just that she unilaterally moves from one domain to the other, but that she continually loops back and forth, unable to be pinned down or contained. Caroline laments that “there is no halfway ground […] a woman is either a lady or not,” and yet, Caddy seems to represent that halfway ground. She represents a site of “lady”hood in that she has necessarily lost it. Further, her wedding is a key event in all of their lives, which does not seem to really take place, and her position in the text is defined by the bombast of her presence and the severity of her absence. Throughout the novel, she is frequently represented hovering in physical interstitial spaces—doorways, windows, gates, even mirrors. She uncatches Benjy from the fence; Quentin views her “in the mirror […] running” and then, “running out of the mirror”; and she often appears in the specific narrow space of doorways rather than inside rooms (4, 44, 81, 89, 124). She moves between and among, directions along which Benjy “sees” that constitute spaces (or breaks) Quentin seems apprehensive to recognize as a legitimate position.
