How does Du Bois refine a central idea in paragraph 5?

In paragraph 5, Du Bois refines the central idea of double consciousness by emphasizing the internal struggle faced by African Americans as they navigate their identities within a racially prejudiced society. He illustrates how this dual awareness creates a conflict between their self-perception and how they are viewed by the dominant culture. By highlighting this psychological tension, Du Bois deepens the understanding of the complexities of race and identity, showing that it leads to a sense of dislocation and alienation. This refinement underscores the broader implications of systemic racism on individual identity.
