Abstract: Justice has been a disputable subject since ancient times.The author thinks that there is two one-sided tendencies in the research of justice.One is abstract. The other is individual.Actually,justice is both a concept and a social reality. We should make researches in justice in three levels-concept,system and daily life-and the three levels are related and influence  each other.Therefore,it is difficult to break away from the dilemma when we view justice in only one of the three levels.

Key words: justice;problem of , justice;conceptual level;institutional level;daily life level
