Why does Stanley seek truth in a streetcar named desire?

In "A Streetcar Named Desire," Stanley Kowalski seeks truth as a way to assert his dominance and maintain control over his household and relationships. He represents raw, unfiltered reality, contrasting with Blanche DuBois's fragile illusions and fantasies. By uncovering Blanche's past and exposing her lies, Stanley aims to dismantle her delusions, ultimately reinforcing his own position of power within the chaotic dynamics of their lives. This quest for truth reflects broader themes of reality versus illusion and the struggle for authenticity in a post-war society.
