Now, it seems that an era from "self" to "self" has arrived, and poetry has assumed this important task. The once beautiful and idealistic poetic style has suddenly entered a new era of materialism, enthusiasm, freedom and openness. Therefore, Whitman is also a pioneer of poetic style. "My own Song" highly affirmed the significance of "I" in life and the world, and loudly announced the arrival of democracy and freedom. This is of great significance at any moment, because he gave the most powerful praise and propaganda to the noblest life and freedom in the world, and the whole poem's interpretation of friendship, equality, optimism and survival is almost perfect. After reading the complete poem, I can't help but feel that my soul has been sublimated and I feel that I am living in a new era.
