Song to Myself, Whitman

   This poem is simply about a thirty seven year old man, celebrating himself. He notes that he is from the soil, as well as everyone else. He came from his parents, who came from their parents, and so on. When the narrator does say that he is from the soil, he states that his tongue, and every atom of his blood came from the soil and air.
   The fact that the narrator said that his tongue came from the soil is important. He does not say his heart, skin, eyes, or any other organ. He only says his tongue and his blood. Blood is one of the most basic necessities of all living creatures. Every single animal has blood. Many animals also do have tongues, however, it seems that when he says his tongue is from the soil, he means his ability to speak. This incredible phenomenon called talking is a very advanced form of communication, however no matter how advanced something is, it still came from nature, and it will never escape the fact that it is from nature. The brain, and the power to think logically is also from nature, even though it is arguably the most advanced quality we have.
   Is this why the author mentioned only his tongue and his blood were made by the soil?
