Step-by-step explanation:
Walt Whitman's poem, Song of Myself, characterizes the relationship between God and humanity as one where God is present in every thing and every person, on par with humans. This is derived from Whitman's transcendentalist connections and his ethos of celebrating the commonalities of nature and humanity. Furthermore, in his poetry, Whitman employs a blend of natural elements and man-made or urban elements, showcasing his unique ability to bridge the gap between the natural world and the urban society he lived in. The voice of Whitman's poetry is often described as expansive, personal, and celebratory, with a soothing rhythm despite its lack of traditional rhyme and meter. Through poems like O Captain! My Captain!, Whitman engages with the Civil War, reflecting the nation's grief over President Lincoln's assassination and symbolizing the end of a tumultuous period in American history.
