One of the important topics of practical philosophy, especially political philosophy, is the discussion on how to access the content of this category of disciplines and the statements related to the subjects of this part of disciplines. In epistemological knowledge, the question of realistic or unrealistic statements of sciences is examined. The theories in the field of political justice can be evaluated in this division and a judgment is made about whether they are right or wrong. This study tries to examine how to develop theories about justice based on a realistic and unrealistic view and the results which these theories produce and concludes that the theory of justice based on the realism accepted by Muslim scholars is not only capable of responding to individual and social needs and establishing the structure of a society, but it also has the capacity to lead man's social and political life and fabric towards true perfection and prosperity. Accordingly, in tyrannical governments, not matter how good they are – which are concerned with the administration of justice in society even on the supposition that in democratic governments there is a necessary and sufficient condition for administering in the society validity of justice is questioned because fulfillment of justice in society can only be valuable by public participation and consent. Therefore, a democratic Islamic government is the most favorable form of government in which the ground is prepared for achieving justice in Islamic society.
