In this poem, Walt Whitman has beautifully brought out the contrast between animals and human beings. Animals are generally simple in nature whereas human beings are generally greedy, selfish and very complicated. He is very happy with the easy going nature of animals and he wants to follow them.
The poet Walt Whitman is desirous to live among the animals as he thinks that they are self contented and serene. They are wise and this is the reason why they never bewail of their lot and condition. They do not weep for their sins and they have no care to worship even God. They are always satisfied and do not need to possess things. They respect none including their ancestors and they remain indifferent in their pleasure and pain. For this reason, the poet wishes to learn from animals. They do not have any kind of falsehood. They are free from all types of trivial anxieties, so they are still living their natural life.
