Malamud's short-story "The Magic Barrel", collected in the National-Book-Award-winning collection of the same title, potrays the quest for love of Leo Finkle, a Jewish American studying to become a rabbi. He has immersed himself so much in his studies that he suddenly discovers his life to be empty and passionless. In addition, he also becomes aware that his search for God and his religious calling were not dictated by his love for God and fellow human beings, but by his indifference to them. Indeed, his love for Stella is defined as "his own redemption", that is a way to start a new and more positive life. This possibility of redemption seems to be in tune with Malamud's artistic credo that
