The narration by black characters demonstrates the widespread existence of double consciousness. W.E.B DuBois, the early 20th century African-American scholar, coined the concept of double consciousness to express the way in which American blacks have an identity reserved for themselves and one reserved for whites. The public personas of old men in the novel long have silently agreed to their subjugation. When transformed into narrators however, their spirit and dreams of willful action become evident. The idea of dual identities also is suggested by the characters' names. Each of the characters has two names—his formal name and the name by which he is most commonly known. The formal name belongs to the world of documents and civil rights, the world to which the black men have always been denied entry. The informal name reflects their character and its style. The old black men always have lived with these two separate selves. With the events at the Marshall Plantation they are able to bring their separate names together. The spirited internal personas become evident as the characters narrate their tales. In the final trial, the characters also boldly refer to each other by their nicknames rather than their formal ones. At the novel's end, the old men still possess double consciousnesses once described by DuBois, yet the relationship of these two identities has grown closer together.
Gaines demonstrates social distinctions both between and within the races. The whites are strictly divided between the white landowners and the local Cajuns, with the landowners believing themselves superior. Likewise, the blacks use the issue of the lightness of skin tone as a sign of social status. The development of characters within this novel shows all these social hierarchies to be without basis. Bea and Jack Marshall, for example, believe themselves superior but are truly drunken idlers. Mathu believes himself superior for being pitch black, but by the end of the book, he realizes that the men's actions define their selves, not whether they have traces of white blood. With this analysis, Gaines exposes the social hierarchies of the South keenly and in doing so exposes the foolishness of their mere existence.
The tractor symbolizes the agricultural mechanization that has taken place with the growth of Cajun farming and this mechanization's effect. The arrival of the tractor with the Cajuns shifted the traditional means of local black life. Mechanization reduced the need for labor. The community of blacks who once cared for the land became suddenly unemployed, and most of them moved away. While the plantation once was carefully maintained by those who worked it, now only the old remain and the plantation's buildings are deteriorating. The image of the tractor is seen near Beau's dead body and later serves as a bastion for the Cajuns during the battle. Overall it is a negative symbol that suggests increased hardships for the local blacks. The tractor was the primary tool of the Cajuns that pushed the blacks off the land.
Like the tractor, the sugar cane suggests the way that the Cajuns have changed the local agriculture. The sugar cane represents the times when the blacks worked the land and their community thrived. The Cajun farmers have destroyed the cane fields with their farming, much in the way that they have destroyed the old men's previous way of life. The empty cane fields seen on the way to the Marshall Plantation evoke the image of old houses from which good friends have moved. The cane is gone and destroyed just as familiar days of the past have disappeared. Additionally, the sugar cane also grows wildly in some areas and may even soon overrun their local graveyard—a clear symbol of how the Cajuns has pushed them from their ancestral land. The symbol of sugar cane also contains a textual reference to Jean Toomer's classic book Cane, a book that examines the vibrancy of early 20th century black life by interweaving poetry and fiction. In Toomer's book, as in Ernest Gaines's, the sugar cane represents the beauty and pain that African-Americans experienced as they worked for many years close to the land.
