Living in a country or voting in its elections raises a question: what have we authorized? An explanation of political consent, its conditions, and its scope.

Imagine someone who stays in their country because they care for their parents there, have a job, and speak the language. They obey the law while disagreeing with the government. Is it reasonable to say that, by staying, they have authorized those who govern?

Political consent can be understood as a person's authorization for another person or institution to exercise a particular kind of political power over them. This definition places individual choice at the center of the problem: who agrees, what they agree to, and how they express it. It reflects the voluntarist approach, which seeks to ground authority in a decision made by those subject to it.

The difficulty emerges when we apply that principle to everyday life. Obeying, staying, and voting are observable actions; establishing what authorization they convey requires a further argument.

What a person would have to agree to

Before looking for signs of consent, we need to specify its object. Joining a political community, accepting a decision-making rule, and choosing a representative are different acts. None necessarily means approving every subsequent measure.

Locke separates two stages: individuals agreeing to form a community, and that community acting through the majority. Initial consent establishes a body capable of making decisions without requiring unanimity for each one. He sets this out in §§95–99 of the Second Treatise of Government.

This distinction explains how authorization and disagreement can coexist. Someone who accepts a procedure may lose a vote and still recognize that procedure. But we must still establish that the person accepted it: the existence of a majority does not, by itself, prove that every individual gave authorization.

It also helps to distinguish related concepts. Consensus is agreement in opinion; approval expresses a favorable judgment. Consent gives authorization. Someone may consider a policy sound without recognizing its proponent's right to impose it, or recognize an authority while judging its decision mistaken.

Key idea: Attributing consent requires specifying which power was authorized. Support for one decision does not establish acceptance of any future exercise of power.

How to recognize authorization

We can organize the inquiry around four questions: what conduct expresses acceptance, whether the person understands that meaning, whether they act voluntarily, and whether they can refuse what is proposed. These are questions used here to examine the problem, not a universal legal test or a checklist accepted by every theory.

The first question concerns a clear expression of acceptance. A direct statement provides stronger evidence than ambiguous conduct. If silence is to count as acceptance, we need to explain why it carries that meaning in the particular context. The mere absence of protest leaves other explanations open.

The second concerns information. Here, understanding means knowing what one's action is being taken to authorize, not foreseeing all its future consequences. If someone believes they are choosing between candidates, it would take a further argument to show why that act also commits them to obeying entire institutions.

Voluntariness and the possibility of refusal complete the inquiry. An alternative may formally exist yet be impracticable because of its costs. This does not mean that any difficulty invalidates every choice, but it does require examining the actual options available to the person said to be consenting.

These questions draw on problems raised by Locke, when he asks what constitutes a sufficient declaration of consent (§119), and by Hume, when he discusses awareness of choosing and the difficulties of emigration (Of the Original Contract, paragraphs 23–24). The disagreement turns precisely on which actions suffice, and under what conditions.

Express, tacit, and hypothetical consent: what each establishes

Express consent is communicated directly. A declaration of membership offers a conceptual example: it makes explicit the intention to join a community. Its clarity does not remove questions about coercion, understanding, or scope.

Tacit consent is inferred from conduct whose meaning, in the circumstances, would be acceptance. In §119, Locke connects the enjoyment of possessions or any part of a government's territory with an obligation to obey for the duration of that enjoyment. The controversy is whether such conduct actually expresses a sufficient choice.

Hypothetical consent answers a different question: what people would accept under specified imagined conditions, such as conditions of impartiality. It can support a defense of the justice of certain rules. Describing what someone would accept, however, does not establish that they have accepted it. The Stanford Encyclopedia of Philosophy entry “Political Obligation,” §1.3 explains this distinction within the debate about political obligation.

The decisive distinction is between actual authorization and hypothetical justification. Both an express declaration and tacit conduct purport to show that acceptance has occurred. An imagined choice needs a separate argument to establish its justificatory force.

Key idea: Saying someone would accept a rule under fair conditions may support an argument about its justice. It does not establish that the person has actually authorized it.

Staying and voting: two cases that need context

Staying when leaving costs too much

Return to the person who lives where they have family and work. Their decision to stay has several possible explanations: personal ties, lack of resources, satisfaction with their life, or acceptance of the political order. Simply observing that they remain does not allow us to distinguish among them.

Hume raises this objection to the automatic inference of consent: someone without the means to emigrate, or who does not know other languages, can hardly be said to have the choice that the argument attributes to them. His criticism appears in paragraphs 23–24 of Of the Original Contract (OC 23–24 in the linked edition). This is a philosophical argument about choice, not an assessment of present-day opportunities to migrate.

One might object that this person receives protection and other shared benefits. That opens an argument from reciprocity: perhaps they should help sustain a cooperative arrangement from which they benefit. But receiving something does not, by itself, establish that it was voluntarily accepted. The fair-play theories examined in “Political Obligation,” §4.2 seek to justify duties on that basis and face objections of their own.

Choosing a representative and rejecting one of their policies

Now consider a voter who chooses a candidate and later protests a decision made by that candidate's government. There is no necessary contradiction: selecting a representative and approving every policy they pursue are different things.

Voting can serve an authorizing function. The question is how much it authorizes and under what conditions. It can also be understood as a choice among available options intended to influence the outcome, without settling the voter's entire relationship with the state.

The discussion in “Political Obligation,” §4.1 presents competing interpretations of voting. It would therefore be as hasty to claim that voting never implies consent as to attribute unlimited authorization to it. We need to distinguish choosing a representative, accepting the procedure, and approving particular policies.

Dissent and those who never joined the agreement

A founding agreement raises a further problem: what happens to those born afterward? In §116 of the Second Treatise, Locke holds that a father's commitment does not, by itself, make his child a member bound by that same commitment. One generation's authorization does not establish the personal choice of later generations.

This is a serious difficulty for consent theories. A community needs collective decisions even when its members disagree. Requiring fresh unanimous acceptance of every measure would prevent many issues from being resolved; attributing acceptance to everyone simply because they belong to society would leave the supposed choice unexamined.

Here we should distinguish political legitimacy, which concerns the justification of the right to govern, from individual political obligation: the moral duty to obey the laws of one's own state. These questions are related, but they are not interchangeable.

The absence of consent does not establish that no law gives rise to moral duties. There may be reasons to comply with a particular rule, such as avoiding harm to others, as well as theories grounded in fair play, association, or natural duties. These alternatives are examined in “Political Obligation,” §§2 and 4. Nor should this moral debate be confused with the existence of a legal obligation.

Key idea: Showing that someone has not consented challenges one particular justification for their obedience. Whether other reasons support requiring it remains an open question.

How long authorization lasts and where it ends

Duration deserves as much attention as the initial act. Does authorization last as long as someone enjoys a benefit, for a term of office, or for as long as they belong to the community? What would allow it to end?

Locke draws a distinction with strict consequences for membership. In §121, the obligation arising from tacit consent lasts as long as the relevant enjoyment continues. By contrast, he treats those who join through express consent as durably bound, except in cases of governmental dissolution or separation by a public act. In §122, he adds that the submission arising from such enjoyment does not amount to full membership.

This position rules out presenting his theory as one in which authorization can be revoked immediately at will. Moreover, disagreeing with a policy, replacing a government, and leaving a political community raise different problems.

From a classical liberal perspective, defending individual autonomy requires careful examination of how much power is attributed to a personal decision. This is a normative judgment: the broader the claimed authorization, the more explanation its scope requires. The institutional safeguards governing this relationship are explored in government by consent.

When faced with the claim that “the citizens have consented,” the useful question is what evidence supports it: who gave authorization, through which act, with what alternative, and for how long? If the only evidence offered is residence, silence, or an election result, the step from that conduct to the power being justified still needs explaining.
