Walt Whitman, an American poet, essayist, and journalist, was one of the most significant writers of American literature, and he was widely recognized as such. The human spirit, individuality, democracy, and the beauty of daily life were some of the themes that Whitman treated in his verse, particularly in his famous collection Leaves of Grass. His poems were unconventional in that they used free verse and long lines, but at the same time, they were able to express the full range of human feelings, love, and the universal nature of man. Whitman’s art is still able to reach out to people across the globe and instill in them the ideas of self-expression, bravery, and the enjoyment of both the good and bad sides of life.
