The reality that justice and security are both counted as high virtues for different societies, makes it difficult to answer the question that if they contradict each other which one has to be preferred or what is the relation between these two virtues? In this article, the author defining these concepts and clarifying the positions of contradiction between “justice” and “security” theoretically and practically, will categorize the existing views including security-centered and justice-centered approaches. Afterwards criticizing these two approaches, he presents an alternative standpoint based on interaction. According to this new approach, there should be a distinction between the two main aspects of justice and security (function and foundation). Only then it appears that justice and security do not contradict in linear conditions (security function with justice function and/or security foundation with justice foundation) and such contradiction may only occur in crisscross conditions (security function with justice foundation and/or security foundation with justice function). In such situations also functions will naturally have priority over foundations.
