This essay aims to study Sandel’s theory with its focus on the notion of intersubjective self and analyze Cather’s A Lost Lady from Sandel’s theoretical viewpoint. Rawls’s theory of justice is based on the assumption that self can pursue what is right when it is not affected by others. Sandel argues that Rawls defines self as integral prior to having any experience in society, and from this point of view individuals are indifferent to each other except when they share a common interest. Sandel’s notion of intersubjective self, therefore, does not draw clear boundaries. Rather the intersubjective self takes the boundaries of others and forms it on the collectivist foundations and through relationships. In A Lost Lady Captain Forrester is one of the pioneers who consider their mutual relationships brotherhood because they share spiritual interest as well as economic interest. Captain Forrester forms his self through his relationships with other pioneers and his wife, Marian. Marian has a suspicious past and disparate elements in disposition. But her self is changed and formed as a respectable hostess thanks to Captain Forrester’s steadfast love toward her.
