When looking at the name "Rinehart," the narrator establishes two different parts of the man: rind and heart. The rind is defined as the outer layer or skin of something, whereas the heart represents an inner existence. As the narrator refers to Rinehart as "both rind and heart" (498), he contemplates the ability of man to take on so many different identities on the outside while still remaining one true identity on the inside. He relates back to the words of the veteran when he notes that Rinehart regards his world as possibility, repeating word-for-word the veteran's advice to him that "the world is possibility if only [he'll] discover it" (156). In this case, the veteran is emphasizing the discovery of this world or possibility with the reliance on the self to discover it, encouraging the narrator to write his own history rather than have others write it for him.
Rinehart is a runner, a gambler, a briber, a lover, and a Reverend in the novel. Although his identities to others appear as a mask to them, hiding the others and displaying only one at a certain time, he still remains true to himself in that his life is one of multiple identities. He chooses to use these identities out of his own mind, whereas the narrator is forced to take on names pushed onto him out of his free will.
To the men at the Battle Royal, Norton, and Mary, he's to play the part of the "destiny of [his] people" (32). The attendees of the Battle Royal conclude that the narrator will some day "lead his people i the proper paths" (32), pushing onto him the responsibility for the whole race. According to Norton, he is dependent upon the narrator to "learn [his] fate" (45), which the narrator finds bewildering as the trustee doesn't even know the narrator's name. His disregard for the narrator's identity in place of the identity he places on him shows that the narrator is not in charge of his own being. Mary also extends this leadership role onto the narrator, telling him that he has to lead and fight "and move us all on up a little higher" (255), telling him this even before she learns his name.
For Bledsoe, Kimbro, and Brother Jack, the narrator's identity is unnecessary as his only role will be to be used as a resource of sorts. Bledsoe tells the narrator that he doesn't exist, that he's "nobody" (143). This insistence on the narrator's lack of identity is held when Kimbro instructs him to obey everything he says, leading the narrator to believe that he "wasn't supposed to think" (200). This loss of thinking for one's self displays a plunge out of history in that the narrator loses control of his own history, given more pressure when Brother Jack gives him his new identity. Brother Jack informs the narrator that he is "to answer to no other" (309), encouraging him to forcibly reject his old identity in place of this new one given to him by the Brotherhood.
Throughout the novel., the narrator is unable to discover himself; he states what he "would be no one except [himself]--whoever [he] was" (311). This inability of his to realize his true identity hinders him from reaching a true freedom, from being his own father, as the veteran had advised of him. Although he realizes that "[he'll] be free" (243) once he discovers who he is, his identity is only constructed by the individuals and groups he encounters.
