Justice and equality
The concepts of equality and justice have evolved throughout history. In antiquity Aristotle faced justice with the same result. And Aristólica equality manifests itself in three ways giving rise to three concepts of justice: distributive, commutative and legal. Distributive justice is based on the principles of proportional and fair equality, intending to establish a just social order, but some consider unfair to give everyone the same treatment as in the case of a criminal. The commutative justice manifests itself in personal relationships between individuals, regulating coexistence among people who are obliged to respect the basis of principles of equality. Legal justice is based on the rule of law, defending the adjustment of the law to particular concrete cases and then speaking in equity as a way to provide a better solution to these cases. The design of Aristotle justice remained unchanged until the appearance of the Renaissance that imposes another concept of equality. It is in this context that the Rawles theory. Rawle says that all men are equal before the law and all have equal rights, but the knowledge of equality does not stop there knowing the difference. Rawle advocates a just society resting on two assumptions: the equality of all men and the respect of equality of all of them, developing around two principles: equality in relation to a set of fundamental freedoms such as freedom policy , expression and conscience, according to the view that the common good is superior to the individual good; and the difference principle that guarantees civil protection and defends an original agreement between people in order to ignore their position to be a fair distribution of goods in order to favor those most in need.
