Abstract: This paper is an attempt to analyze the social mechanism of compensation. Firstly， applying the legal methods to the analysis of the story of Joel Feinberg’s Hikers has met difficulty. Secondly， Parfit’s， Jeske’s， and Montagues’s views on whether compensation holds morality are reviewed around the story’s dilemma when utilitarianism is involved. Such analysis gradually reveals the morality in compensation， which is followed by the final discussion on compensation accomplishment. In essence， it is a discussion of the feasibility of compensation accomplishment from a social theoretical perspective， that is， the social systems theory leading to the Societal Common.

Key words: compensatory mechanism, morality, the Societal Common
