A Theory of JusticeA Theory of Justice is a 1971 work of political philosophy and ethics by the philosopher John Rawls (1921–2002) in which the author attempts to provide a moral theory alternative to utilitarianism and that addresses the problem of distributive justice (the socially just distribution of goods in a society). The theory uses an updated form of Kantian philosophy and a variant form of conventional social contract theory. Rawls's theory of justice is fully a political theory of justice as opposed to other forms of justice discussed in other disciplines and contexts.
State of natureIn Ethics and political philosophy, in social contract theory, religion, and international law, the term state of nature describes the hypothetical way of life that existed before people organised themselves into societies. Philosophers of the state of nature theory propose that there was a historical period before societies existed, and seek answers to the questions: What was life like before civil society?, How did government emerge from such a primitive start?, and What are the hypothetical reasons for entering a state of society by establishing a nation-state? In some versions of social contract theory, there are freedoms, but no rights in the state of nature; and, by way of the social contract, people create societal rights and obligations.
Social contractIn moral and political philosophy, the social contract is a theory or model that originated during the Age of Enlightenment and usually, although not always, concerns the legitimacy of the authority of the state over the individual. Social contract arguments typically are that individuals have consented, either explicitly or tacitly, to surrender some of their freedoms and submit to the authority (of the ruler, or to the decision of a majority) in exchange for protection of their remaining rights or maintenance of the social order.
UtilitarianismIn ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for all affected individuals. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described utility as: That property in any object, whereby it tends to produce benefit, advantage, pleasure, good, or happiness .
Political philosophyPolitical philosophy or political theory is the philosophical study of government, addressing questions about the nature, scope, and legitimacy of public agents and institutions and the relationships between them. Its topics include politics, liberty, justice, property, rights, law, and the enforcement of laws by authority: what they are, if they are needed, what makes a government legitimate, what rights and freedoms it should protect, what form it should take, what the law is, and what duties citizens owe to a legitimate government, if any, and when it may be legitimately overthrown, if ever.
