Any theory or practice that encourages members of a society to behave more justly toward each other. The "social justice” concept of fair and just relations between the individual and society is characterized and measured by the distribution of wealth, natural resources, goods and services, opportunities for personal activity, social privileges and other values related to habitat and well-being.
In many human cultures, the concept of social justice often has entailed processes of ensuring that individuals fulfill their societal roles and receive their due from society. The current global grassroots movements for social justice emphasize breaking barriers to social mobility, maintain safety nets and economic equity. For example, a social justice policy may seek to alleviate the consequences of racism, patriarchy, colonization or other form of unequal treatment and/or improve relations between classes. In economics, social justice is associated with policies seeking to help the poor, especially but not necessarily at the punitive expense of the wealthy. While generally critical of capitalism, social justice is not necessarily a socialist ideology, and is often opposed to experiments in socialism due to human rights concerns or similar grounds.
Social justice assigns rights and duties to the institutions of society, which enables people to share equitably the basic benefits and burdens of cooperation. The relevant institutions often include those responsible for taxation, social insurance, public health, public school, public services, public hygiene and sanitation, environmental goods and natural resources (land, water, etc.), labor law and regulation of markets, to ensure fair distribution of habitat, wealth and equal opportunity, and the attainment and maintenance of well-being.
Interpretations that relate justice to a person’s reciprocal relationship to society are mediated by differences in cultural traditions, some of which emphasize the individual responsibility toward society and others the equilibrium between access to power and its responsible use. Hence, social justice is invoked today while reinterpreting historical figures such as Bartolomé de las Casas, in philosophical debates about differences among human beings, in efforts for gender, ethnic, and social equality, for advocating justice for migrants, prisoners, the environment, and the physically and developmentally disabled.
While the concept of social justice can be traced through the theology of Augustine of Hippo and the philosophy of Thomas Paine, the term “social justice” became used explicitly in the 1780s. The Jesuit priest Prospero (Luigi) Taparelli d’Azeglio (1793–1862) is typically credited with coining the term, and it spread during the revolutions of 1848 with the work of Antonio Francesco Davide Ambrogio Rosmini-Serbati (1797–1855). However, more-recent research has shown that the expression "social justice” is even older (before the 19th Century, for example, in Anglo-America, the term appears in The Federalist Papers.
