Saul Bellow, who was awarded the Nobel Prize for Literature in 1976, is one of the American Jewish novelists whose idea comes from the Bible. He regards a writer's role as "a cure of soul" and affirms the "savior faculty" of the art. The most important idea in Bellow's works is the affirmation of human values and the salvation of "the real soul" . The purpose of this paper is to investigate "the real soul" and "the pretender soul" in this work. Bellow emphasizes that human beings have a lot of souls, but there are two main souls; the real soul and the pretender soul. From the biblical view, the real soul means the truth, the image of God, while the pretender soul means the evil spirit, Satan, who betrays God. Tommy Wilhelm recovers the real soul through the death of his pretender soul and find brotherhood by throwing away the death-in-life in which God is Mammon. In conclusion, human beings can recover the real soul only through love, and then, human beings can love not only their neighbors as themselves but also all mankind. Bellow's idea that love is the only way of curing "the pretender soul" is embodied well in this novel.
