The poet Walt Whitman compares man and animals in this poem. He finds that animals possess virtues that men lack - they are placid, self-contained, and do not sweat, whine, or weep about their condition. They are not dissatisfied or driven mad by the desire to possess things. The poet wishes to live with animals rather than human beings, who are selfish, false, and always dissatisfied. Animals provide tokens of the poet's own nature by their peaceful possession of kindness and sympathy for all.
