Who is Walt Whitman from Writings, 1902-1910 and what is their importance?

All natural objects seem to have a charm for Walt Whitman. His favorite occupation appears to be strolling or sauntering about outdoors looking at the wildlife. These things seem to give him pleasure far beyond what they give to ordinary people. He likea all the men, women and children he sees. He never argues and does not speak of money. Whitman takes pleasure in the opposition of enemies and justifies their position. He doesn't experience fretfulness or antipathy, complaint and never complains.
