Final answer:
Walt Whitman's 'Song of Myself' explores the common human experience, with the phrase 'for every atom belonging to me as good belongs to you' underscoring the interconnectedness of all people.
Step-by-step explanation:
In Song of Myself, Walt Whitman introduces the idea of a common human experience by stating, "I celebrate myself, and sing myself, And what I assume you shall assume, For every atom belonging to me as good belongs to you." Whitman's poetry often presents a challenge to first-time readers due to its lack of rhyme and meter, appearing disjointed and meandering. However, many find comfort in the poem's simplicity and deep cadences. Whitman's work reflects the American spirit by connecting the individual to the collective experience, embracing both high and low culture, and celebrating ordinary life and the common people. With the publication of Leaves of Grass in 1855, Whitman established himself as an iconic voice in American literature, with Song of Myself playing a significant role in this reputation.
