What are the three principle of …

The three principles of justice outlined in the chapter are discussed below:
(i)First, one of the principle in the principle of treating equals equally. It is considered that all individuals share certain characteristics as human beings. Therefore they deserve equal rights and equal treatment. Some of the important rights which are granted to most liberal democracies today include civil rights such as the rights of life, liberty and property, political rights like the right to vote, which enable people to participate in political processes and certain social rights which would include the right to enjoy equal opportunities with other members of the society.
(ii)Second, apart from the equal rights, the principle of treating equals equally would require that people should not be discriminated against on grounds of class, caste, race or gender. They should be judged on the basis of their work and actions and not on the basis of group to which they belong.

Therefore, if two persons from different castes participate in the same type of work, whether it be breaking stores or delivering pizzas they should receive the same type of reward.
