John Rawls wrote the famous book on social justice named "A Theory of Justice". John Rawls was an American philosopher who believed in the liberation tradition. In his book, Rawls provided the theory of social justice based on two principles. He stated that each person in the society is free and must be respected. The social opportunities and the economic opportunities must be equally available to all. Thus he believes that the inequalities in the society should not unfairly burden any segment of the society.
