Justice is a fundamental concept in political philosophy, ethics, and social theory that investigates principles concerning fairness, equity, rights, and the proper ordering of social relations and institutions. As an academic concept and field of inquiry, it examines criteria for the just distribution of resources, opportunities, and burdens, the rectification of wrongs, the legitimate exercise of power, and the moral responsibilities individuals and societies have towards one another, serving as a critical framework for evaluating legal systems, political structures, and moral conduct.
