Core Idea

Consent theory grounds legitimacy in agreement: government authority is justified only when citizens have consented to it. Consent can be actual (explicit agreement), tacit (continued residence implies acceptance), or hypothetical (rational people would agree under specified conditions). The puzzle is that most people never explicitly consent and are born into existing states. Theorists resolve this through various mechanisms: express consent for those who explicitly commit, presumed consent for residents, or hypothetical-consent devices like Rawls's original position.

Explainer

From social contract theory you know that Hobbes, Locke, and Rousseau all grounded political authority in some form of agreement among individuals. The core intuition is straightforward: authority over a person is presumptively illegitimate unless that person has in some sense authorized it. This is the same principle operating in everyday contexts — a surgeon may not operate without informed consent, an employer may not impose new conditions without agreement. Consent theory applies this same logic to the state: the authority of governments to make laws, collect taxes, and coerce compliance requires a justification, and consent is the most intuitive candidate.

The trouble begins immediately with actual consent. Locke thought that residing in a country and using its roads and protections constitutes tacit consent — you implicitly agree to the authority of the state by choosing to remain. But critics, most prominently Hume, pointed out that this is not real consent at all. Most people have no realistic option to leave — they are born into the state, speak its language, have all their ties there, and emigration is costly or impossible. Saying "you consent by staying" when leaving is not a genuine option is like saying a prisoner consents to imprisonment by not escaping through the locked door. For consent to be morally binding, it must be freely given with real alternatives available.

The more sophisticated response is hypothetical consent: we ask not whether people did consent but whether they *would* consent under certain idealized conditions. Rawls's original position is the canonical example — rational individuals, ignorant of their social position, would agree to certain principles of justice. This sidesteps the problem of actual consent by grounding legitimacy in what rational agents would choose if fully informed and impartially situated. But critics reply that hypothetical consent is not real consent at all. If I would consent to your taking my car if I were fully rational and well-informed, that does not mean you may take my car without asking me. What justifies authority is actual agreement, not a counterfactual about idealized agents.

A further distinction separates the content of what is consented to from the fact of consent. Even if someone explicitly consents to a government's authority, it is unclear how far that consent extends. Did signing a constitution commit me to every law subsequently passed? Did my ancestors' consent bind me? Most theorists now treat consent not as the sole foundation of legitimacy but as one element within a broader theory that also includes fair procedures, protection of rights, and just outcomes. The practical legacy of consent theory is less a complete answer than a set of structural requirements: legitimate governments must create genuine channels for exit and voice, must not coerce acquiescence by eliminating alternatives, and must remain accountable to the ongoing agreement of those they govern.
