Ethical values attain significance for an individual only through a choice to embrace them. The seducer wins the heart of a young woman, inducing here to pursue him. When his seduction succeeds, he abandons her at once, having reached the highest point of pleasure. All that would have remained would be the tedium of marriage. In the second part of the book, Kierkegaard's character Judge Willhelm spins out lengthy sermons about the virtues of the mundane ethical life of faithful wedlock.
Ethical laws are universal, subject to no exception.
Yet faith could call upon the individual to violate them if it were the will of God. Such is the story of Abraham, who was willing to act against a most basic human moral norm, the protection of one's own offspring, because God asked him to kill his son.
