In the excerpt from "Notes of a Native Son," James Baldwin expresses the connection between the historical context of racial prejudice and its physical effects on his father by highlighting the tension in his father's body. This tension reflects the broader societal tension between oppressors (white people) and the oppressed (Black Americans) in early 20th-century America. Baldwin reveals how his father's posture, proudly pursed lips, and rigid carriage symbolize the weight of white people in the world, signifying the oppressive nature of racial prejudice.
By emphasizing the physical manifestation of stress and bitterness in his father, Baldwin illustrates how the historical context of racial prejudice directly impacts individuals on a personal and physical level. The tension in his father's body serves as a metaphor for the larger systemic issues of racism and discrimination faced by Black Americans during that time. This tension not only affected his father but also had the potential to harm Baldwin himself, as seen in the statement, "the bitterness which had helped to kill my father could also kill me."
Therefore, the connection Baldwin makes between historical racial prejudice and its physical effects on his father lies in the representation of the tension, stress, and weight of white oppression manifested in his father's physical demeanor, symbolizing the broader societal struggles faced by Black Americans during that period.
