"For the Christian, every man is homo viator, whose sole purpose (and soul's purpose) is to travel through the adventure of life with the goal of getting to heaven, his ultimate and only true home, facing many perils and temptations along the way. The enemy of homo viator is homo superbus (proud man), who refuses the self-sacrifice that the adventure of life demands and seeks to build a home for himself within his "self." Such a man becomes addicted to the sins that bind him, shriveling and shrinking to the pathetic size of his gollumized self. The drama of life revolves around this battle within each of us, between the homo viator we are called to be, and the homo superbus we are tempted to become. This drama is mirrored in Middle-earth in the struggles between selflessness and selfishness within the hearts of hobbits and men."
