On Theories of Social Justice

This paper attempts to establish two principles of social justice by analyzing various social justice theories,namely,distribution based on one's needs,on one's virtues,on one's abilities,on one's contributions,and distribution based on equality.The two principles are as follows:(1)The substantial principle:the real source that determines one's interests is the contribution that person makes.Distribution should be in line with the amount of contribution one makes and responsibility one fulfills.(2)The potential principle of social justice:one's virtues and abilities are the potential basis on which designation of his position rests.A person's position and interests,then,should be measured against his virtues and abilities.
