Faith, Hope, Mercy, Envy, Ignorance, Guilt: These are not abstract concepts, but the names of vividly imagined, sharply drawn human characters encountered by Christian, the hero of The Pilgrims Progress. In John Bunyans seventeenth-century allegory of the souls search for salvation, each step along the way becomes a dramatic rendering of an inner state of the human psyche. As Christian journeys from the wilderness of this world to the glory of the Celestial City, he confronts a seemingly endless array of temptations, threats, and dangers, including the nearly irresistible allure of material splendor at Vanity Fair the crushing psychological burden of depression and despair in the Slough of Despond and the fear and uncertainty that eats away at faith in Doubting Castle.
