Born two centuries into the future, George Quixby is a most extraordinary man of remarkable skills. He is consistently at the top of his classes in high school, college, and the military academy, where he moves quickly through the ranks to become a colonel. Because of his special skills in mathematics, the sciences, languages, and every other discipline, he is called upon to direct many new private and public ventures, recording one success after another. Among those successes are a project providing all types of human parts to perpetuate life, a chemical-food division that eliminates the need for agricultural products, a transportation division that creates a personal flying machine making airlines a thing of the past, and several other divisions devoted to developments of the future. At his side throughout his career is Jean Marshall, his secretary and confidante. They are in agreement on all aspects of life but one: He does not believe in God or a hereafter, while she is a devout believer. The final adventure takes Quixby and Jean on a spaceship to another universe and a planet scientists say is a replica of earth. As they land, they are overwhelmed to witness a valley that is a duplicate of the Earthas Holy Land. The bookas denouement of faith is unequaled in American literature.
