Two Keys to American Legitimacy

Thomas Jefferson built an entire theory of justice and political authority into these famous words: We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights… That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed… whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it.

The theory has two parts. On the one hand, Jefferson claims that governments exist to protect natural rights. On the other hand, the government derives its “just powers” from the consent of the governed, which the people can withdraw. A government is legitimate only when it secures natural rights as a matter of justice and operates through popular consent as its source of authority.

Contemporary political theory sees a contrast where Jefferson sees a unity. Modern political philosophy forces us to choose: either rights exist prior to politics, and government must respect them (natural law), or all political authority derives from agreement, and rights are what we contract for (contractarianism). Each tradition claims to explain both justice and legitimacy, making them appear as rival theories rather than complementary principles.

The Declaration operates a dual-key system where legitimacy requires both keys: rights-respect and contractarian agreement. More provocatively, the Declaration demonstrates this principle through its retrospective withdrawal of consent. This retrospective delegitimation — the formal revocation of an existing government’s authority due to systematic violations — demonstrates how a government loses legitimacy when it violates rights or fails to obtain the people’s consent. Put logically, they are individually necessary and jointly sufficient conditions for legitimate rule.

The justice key rests on natural rights — those rights humans possess by nature of their humanity. Government exists to secure life, liberty, and the pursuit of happiness. Because these rights are inalienable, government cannot legitimately violate them, even with consent. As Blackstone wrote, “no human laws are of any validity, if contrary to this.” Natural rights thus establish both what government must actively secure and what it cannot transgress, which places substantive restraints on government action.

The authority key establishes the right to rule, not merely just rule. It is one thing for the state to act justly, quite another why it, rather than some other organization, gets to protect our rights. The American government may rightfully enforce Americans’ natural rights, while the French government may not. Both might be equally just, but only the American government has legitimate authority over Americans. Authority, according to the Declaration, arises from the consent of the governed. The principle is that among natural equals, no one has inherent authority to rule. Political power, therefore, must arise from consent. As Locke wrote, “No one can be…subjected to the political power of another, without his own consent” (Second Treatise §95).

The two keys work together via a priority rule. Rights set the ends and boundaries of government, and consent authorizes government to act within those limits. To secure life, liberty, and the pursuit of happiness, governments thus need just powers, as the Declaration puts it. The powers must conform to natural law and so respect natural rights, which makes them just. But they are powers because the people consent to their exercise. Consent authorizes government action, but only within the boundaries set by rights. The two keys work together; they are not alternatives.

Why insist on both keys? To see why, imagine what happens when one is missing. Government can fail in two ways: 1. It is unjust despite being consented to, as in a majoritarian tyranny; 2. It is just in aims but lacks consent, as in a benevolent despotism. The Declaration condemns both failures. Hence, there is a need for the dual-key system.

Most historical narratives begin with Thomas Hobbes’s social contract theory. That is a mistake. Social contract thinking appears much earlier. Francisco Suárez developed a social contract view of political authority in his De Legibus (1612), decades before Hobbes. For Suárez, political authority originates in the community, not in the divine designation of rulers, because of our natural equality. This authority must serve the common good as specified by natural law, showing that consent theory emerges from within the natural law tradition.

We encounter the idea of the social contract even earlier in Richard Hooker’s Laws of Ecclesiastical Polity (1590s), which Locke cites liberally. Hooker bridges the Catholic scholastic tradition to the English Protestant context. For Hooker, human laws become “available by consent,” but they must accord with higher law. This idea reaches the Declaration through Locke.

Thomas Hobbes (1651) represents a divergence from this tradition. He embraced consent as a principle of authority, free from the constraints of traditional natural law. Hobbes is sometimes read as a natural-law theorist, and he writes in those terms, but his law of nature arguably reduces to rules of self-preservation. Crucially, his sovereign faces no moral limits once established. Americans deliberately rejected Hobbes’s model, holding contractarianism and natural law together.

John Locke (1690) provides the synthesis that Jefferson adopts in the Declaration. For Locke, consent creates government specifically to secure pre-political rights. Rights exist prior to government, following the natural law tradition. But government needs consent to have authority, following the contractarian tradition. Locke thus unites what Hobbes had separated. Government failure on either dimension triggers the right to “alter or abolish it” — language that appears verbatim in the Declaration.

America innovated by making Locke’s dual requirement operational in actual revolution. Theory became practice. The Declaration withdraws consent based on systematic rights violations. Philosophical theory thus guided revolutionary action. From Suárez through Locke, consent theory emerged within natural law, not against it. Americans proved both were necessary by withdrawing consent when government failed either test.

The Declaration opens by declaring “We hold these truths to be self-evident, that all men are created equal.” These truths are discovered by reason, not created by consent. Natural equality is the first truth Jefferson emphasizes, establishing that rights are “endowed by their Creator” and exist prior to government. These rights are “unalienable,” meaning they cannot be surrendered even through consent. Thus, these moral fixed points limit government power before government even exists.

Jefferson pivots from rights to consent in the same breath: “That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed.” Note the purpose clause: governments exist “to secure these rights.” Government derives not all powers from consent, but “just” powers. Consent authorizes government action but only within rights-respecting boundaries. Securing rights is the purpose; consent is the method.

The Declaration makes consent conditional on performance: “whenever any Form of Government becomes destructive of these ends.” Failure to secure rights voids governmental authority. When government becomes a threat to the very rights it exists to protect, the people acquire the right to alter or abolish it. This right activates only when governments fail their core purpose. Critically, the people themselves judge when this line has been crossed. Consent is no blank check.

The Declaration primarily theorizes withdrawal of consent, not its granting. It both describes and performs retrospective delegitimation. The document announces the withdrawal of consent from English rule, not the creation of a new constitution. Unlike social contract theories that focus on original consent, this is about ending a political relationship.

The grievances demonstrate that the justice condition and the authority condition were systematically violated. Some failures concern natural rights, such as quartering troops in homes, denying trial by jury, and cutting off trade. Other grievances concern violations of consent, such as taxation without representation and the dissolution of legislatures. Some grievances violate both conditions at once, such as imposing taxes without consent, which violates both natural property rights and procedural authorization. This dual–failure pattern confirms that the Declaration advances a dual rights–contract theory.

Natural rights alone cannot create society-wide enforcement. Rights do not specify their own interpretation, and biased people enforce them with disproportionate means. When individuals enforce their own rights, chaos results. This is Locke’s “inconvenience” in the state of nature: when people judge their own cases, bias and conflict follow. An impartial public authority must settle disputes, but such an authority requires consent. Rights specify what to protect, not who may protect them. Therefore, we must leave the state of nature through a social contract.

Consent alone is morally empty. Lacking natural law grounding, consent lacks moral significance. Natural law provides the moral standards that limit what people can consent to. Otherwise, people could sign away all their rights. But the Declaration declares certain rights are inalienable. Consent without moral content can justify anything. The Declaration prevents this by grounding consent in objective moral constraints.

When both keys fail, the people can rightly exercise a special power to create a new government. Here, we mean a power beyond elections and voting. This is constituent power, the power to re-create the political order itself. The Declaration both theorizes and exercises this power, constituting the colonists as “one people” separate from Britain. This revolutionary form of consent is not routine democratic consent. The people step outside and judge the existing system, withdrawing their authorization and preparing to establish it anew.

Emergency powers present a hard case for the Declaration’s dual-key theory because they suspend normal consent procedures during crises to protect rights. The tension is acute: emergencies demand swift, unilateral action, but such powers threaten both democratic consent (no time for legislative deliberation) and individual rights (expanded state authority restricts liberties). The dual-key theory suggests that legitimate exercises of emergency power must satisfy both keys, which requires two conditions: first, the people must have consented in advance to a constitutional structure that specifies emergency powers and their limits; second, those powers must operate to preserve our rights, rather than permanently expand the state power. The danger lies where “emergency” becomes a permanent excuse to govern without consent or respect for rights. COVID lockdowns and post-9/11 security measures illustrate how emergency powers can exceed their justification and outlast their purpose. The dual-key test provides clear criteria: Do the powers operate within pre-authorized constitutional limits? Do they genuinely aim to preserve the system of rights rather than expand state power? When either answer is no, emergency rule becomes tyranny.

Contemporary political theory presents natural rights and the social contract as rival approaches to politics. The Declaration exposes this as a false dichotomy, revealing that the two theories answer different questions. Natural rights theory tells us what governments must do to be just — what ends they must serve and what limits they must respect. Contractarianism tells us when governments have the authority to enforce justice, explaining why the American government can enforce rights for Americans. Once we recognize that justice and authority are distinct questions, the apparent conflict between the two traditions dissolves. The Declaration’s genius is to recognize both elements as individually necessary and jointly sufficient for legitimate government.

The American experiment’s unique contribution lies in combining natural rights and the social contract rather than seeing them as separate options. We understand that natural rights define what government can and cannot do. We also acknowledge that, among equals, political authority must be based on consent. The Declaration shows that legitimate government requires both: justice determines the purpose of government, and authority provides the justifiable means.

Contemporary political theory obscures this achievement by presenting us with a false choice between these traditions. To understand what the American founders accomplished, and what our constitutional system requires, we must recover the synthesis that the Declaration declared. The Declaration’s preamble offers more than a justification for independence; it articulates principles of political legitimacy that remain essential for a free society.
