Social Contract Theory
Social Contract theory holds that the legitimacy of political authority — and of the moral rules enforced by it — derives from the consent, actual or hypothetical, of those subject to it. Thomas Hobbes's 'Leviathan' (1651) argued that rational individuals in a pre-political state of nature, where life is 'solitary, poor, nasty, brutish, and short', would alienate their natural right of self-defence to an absolute sovereign in exchange for security. John Locke's 'Second Treatise of Government' (1689) recast the contract as a limited trust: persons retain inalienable rights to life, liberty, and property, and government that violates these rights forfeits its legitimacy. Jean-Jacques Rousseau's 'Du Contrat Social' (1762) reconceived the contract as the constitution of a collective general will (volonté générale) in which freedom and law coincide. After a long eclipse the tradition was decisively revived by John Rawls's 'A Theory of Justice' (1971), whose thought experiment of the original position behind a veil of ignorance generates principles of justice all parties could rationally accept. David Gauthier's 'Morals by Agreement' (1986) developed a Hobbesian variant grounding morality in mutually advantageous bargaining; T.M. Scanlon's 'What We Owe to Each Other' (1998) provides a contractualist account of interpersonal morality.
Worldview
The contractarian inhabits a world in which legitimate authority must be earned, not inherited or imposed, and in which every coercive institution stands under a permanent demand for justification to those who live under it. The fundamental orientation is one of reflective self-government: political order is what free and equal persons would agree to if they reasoned carefully about how to live together. The contractarian is therefore congenitally suspicious of appeals to tradition, divine right, or natural hierarchy as sources of authority that bypass consent. The framework classifies this as None: the social-contract tradition is in the main a secular and rationalist programme that locates the source of political legitimacy in human reason and agreement rather than in any cosmic-ordering principle or personal deity, although Locke famously appealed to a Christian theology of natural rights and Kant retained a residual providentialism. The framework reads this as Constructed moral authority: political and moral norms are products of agreement (actual or hypothetical) among rational persons, justified by what reasonable parties could accept rather than by scripture, tradition, or pure reason in isolation. The contractarian thus combines a strong universalism about the form of justification with a constructivist humility about the content of the principles that emerge from it.
Moral Implications
Contractarian ethics generates strong duties of non-coercion, fair cooperation, and respect for the rights necessary to participate in the cooperative scheme. It is congenial to liberal-democratic constitutionalism, the rule of law, and the protection of individual rights against majoritarian encroachment. Rawls's difference principle — that inequalities are just only if they benefit the worst-off — supplies the tradition's most influential distributive criterion. Contractarianism has been criticised from feminist, communitarian, and post-colonial perspectives for assuming an abstract, free-standing rational chooser and for excluding from the contracting circle those (children, the severely disabled, non-human animals, future generations) who cannot reciprocate; contemporary work has attempted to extend the framework to address these cases.
Practical Implications
Contract theory has shaped constitutional design from the U.S. Bill of Rights to the European human-rights regime; it underwrites the standard practice of justifying coercive policy by appeal to the consent or reasonable acceptability of those affected. In bioethics, contractualist reasoning shapes principles of informed consent and the just allocation of scarce medical resources. In contemporary politics it provides the theoretical backbone of public-reason liberalism — the demand that fundamental political decisions be justifiable to all reasonable citizens — and of constitutional theories of judicial review. The tradition's practical limits are most visible at the boundaries of the contracting community: refugees, future generations, and the global poor remain test cases.
I. Time
Time is substantival, one-dimensional, linear, continuous, and non-deterministic. The contract itself is largely hypothetical and a-historical — it is a heuristic device for justification rather than a dated historical event — but the political orders it justifies unfold in ordinary historical time. Locke and Rousseau differ from Hobbes in seeing a real developmental sequence from pre-political condition to civil society, but the binding force of the contract does not depend on its actual historical occurrence.
Attributes
II. Space
Space is substantival, finite, flat, and local — the ordinary territorial space within which political authority is exercised. The contract presupposes a bounded jurisdiction within which the sovereign's writ runs and outside which it does not, which is why contractarian theory has historically been uncomfortable with questions of international justice (a discomfort that Rawls's 'The Law of Peoples' [1999] sought to address).
Attributes
III. Matter
Matter is substantival, finite, three-dimensional, conserved, and local in the standard modern sense. The contractarian tradition takes for granted the material world of bodies, resources, and territories and is concerned chiefly with the rules under which these are to be held, exchanged, and protected. Locke's labour theory of property and Rawls's principles for the distribution of social primary goods both presuppose a finite material world that must be allocated under conditions of moderate scarcity.
Attributes
IV. Observer
The contractarian observer is a rational individual capable of representing her own interests and recognising the rational interests of others. In the canonical thought experiments she is stripped to her bare rational capacities — Rawls puts her behind a veil that conceals her social position, talents, and conception of the good — in order to expose the principles that anyone in her position would have reason to accept. Agency is active: the legitimacy of political order depends on the (actual or hypothetical) reasoned assent of each subject. Observers are plural and formally equal in the contracting situation, even where they differ widely in actual capacities. Knowledge is mediated and partial in the lived world but is artificially equalised in the device of the contract.
Attributes
V. Energy
Energy is substantival, finite, conserved, and irreversibly dispersible in the standard physical sense. The contractarian tradition has no distinctive metaphysics of energy; its concern with material resources extends naturally to energetic ones, and contemporary contractarian work on intergenerational justice (notably the just-savings principle in Rawls) addresses the equitable distribution of the planet's finite energetic inheritance.
Attributes
VI. Information
Information is emergent and conserved in the social sense: the rules of justice, once established, are recorded in constitutions, statutes, and the working understandings of institutions. The contractarian tradition is unusually attentive to informational conditions — Rawls's veil of ignorance is precisely a stipulation about what information may enter political reasoning, and Gauthier's bargaining theory assumes specific informational symmetries between contracting parties. Personal informational conservation is denied: the tradition is generally secular in temperament, with no doctrine of personal survival, though Locke combined his contract theory with a Christian eschatology.
