Solitude: Thoreau reflects on the feeling of solitude. He explains how loneliness can occur even amid companions if one's heart is not open to them. Thoreau meditates on the pleasures of escaping society and the petty things that society entails (gossip, fights, etc.). He also reflects on his new companion, an old settler who arrives nearby and an old woman with great memory ("memory runs back farther than mythology"). Thoreau repeatedly reflects on the benefits of nature and of his deep communion with it and states that the only "medicine he needs is a draught of morning air".
