consent ethics

Works

A code written after atrocity, a report, and the philosophical spine.

• The Nuremberg Code (1947) states the first principle of research ethics: the voluntary consent of the human subject is absolutely essential — written in judgment of experiments conducted without it.
• The Belmont Report (1979) supplies the working framework of respect for persons, beneficence, and justice, and with it the practical machinery of informed consent in research.
• Kant's Groundwork (1785) supplies the philosophical ground: the formula of humanity, on which using a person merely as a means is the paradigm wrong.
• The affirmative-consent literature in sexual ethics develops the conditions — capacity, freedom from coercion, ongoing revocability — that distinguish agreement from acquiescence.

Central ideas

Four conditions and one structural claim.

• Capacity: agreement counts only from someone able to understand and decide, which makes capacity assessment part of the ethics rather than a preliminary to it.
• Information: consent is to something specific; material facts withheld make the agreement void even where the words were said.
• Voluntariness: a yes given where no was expensive is not free — coercion includes structural pressure, not only threat.
• Revocability: consent is continuous, not a signature; withdrawal must remain as available as granting was, or the original agreement was conditional on nothing changing.

Distinctive vocabulary

Five terms whose everyday senses are looser than the tradition's.

• Consent: informed, capacitated, voluntary, revocable agreement. Not permission, and not absence of objection.
• Autonomy: the standing to author one's own course. Not independence, and not doing as one pleases.
• Coercion: pressure that makes refusal costly. Not only threat of force.
• Capacity: the decision-specific ability to understand and choose. Not general competence, and not a diagnosis.
• Assent: agreement from someone without full decisional capacity. Not consent, and the difference is doing real work.

Debates and disagreements

The tradition's quarrels are about how much consent can carry.

• Whether consent is sufficient: critics from feminist and materialist ethics argue that agreements made under structural constraint are formally valid and substantively unfree, so consent legitimates arrangements it cannot examine.
• Whether autonomy is the right centre: care ethics, documented separately in this record, holds that the self doing the consenting is constituted by relationships, which the independent chooser model misses — this is the tradition's most serious internal challenge.
• How much information is enough: full disclosure is impossible and the threshold is contested, especially where a professional's judgment about relevance shapes what the other person can even ask about.
• Whether the model transfers out of the clinic: the machinery was built for discrete interventions, and applying it to continuous relationships — where nothing is signed and everything is ongoing — is a genuine extension rather than a straightforward application.

Intellectual relationships

In this record it works alongside two traditions that press it hard.

• Care ethics is its nearest rival: both are documented here, and their disagreement — the independent chooser against the constituted, dependent self — is stated from both sides rather than harmonized.
• Non-coercive politics, documented separately, shares the anti-coercion commitment but works at the scale of arrangements and institutions rather than of the agreeing pair.
• The economic-class lens supplies the structural objection with force: an agreement made from need is an agreement, and the tradition's own vocabulary strains to say what is wrong with it.
• Discourse ethics, documented here, supplies the procedural cousin — legitimacy from conditions of unforced agreement among all affected, rather than from a bilateral yes.

How it changes this reading

Nine placements, all at the scale of the encounter rather than the contract.

• The tradition's contribution across the presence, agency, and boundary claims is the offer/imposition distinction — availability that keeps refusal costless is the relational form of voluntariness.
• In the through-lines about endings and receiving, it supplies revocability: an exit that costs nothing to take and a gift that creates no debt are what keep an arrangement voluntary in retrospect.
• In the claims about owned needs and chosen attention, it supplies the precondition and the extension: agreement requires a party who can say what they want, and attention is a resource the classical formulations never treated as consentable.
• The guard: this tradition describes conditions for legitimate action toward another, not a scoring system for relationships — and the corpus cites it for structure, never to certify any interaction as consented.

Useful comparisons

Against its neighbours.

• Against virtue ethics: consent asks what conditions make an action permissible, not what a good person would do — the two can diverge, and the tradition is deliberately thinner.
• Against consequentialism: an outcome-improving intervention without consent is exactly what the Nuremberg Code was written to forbid, which makes this tradition a constraint on beneficence rather than a species of it.
• Against care ethics: an ethic of the free chooser against an ethic of the dependent and related self — the disagreement is real and this record keeps both.

Where the ideas meet

What every formulation keeps.

• The person acted upon has standing: their agreement is not a formality to be obtained but the thing that makes the action permissible.
• Silence is not agreement: every serious version of the tradition rejects the inference from absence of refusal to presence of consent.
• Conditions matter more than words: capacity, information, and voluntariness determine whether a yes was a yes.

Where they part

Where versions part.

• On sufficiency: whether valid consent settles permissibility, or whether some things cannot be consented to.
• On what counts as coercion: threat only, or structural constraint and need — a difference that decides whether most economic agreements are free.
• On continuity: a signed moment against an ongoing state, which is where the clinical and relational versions genuinely diverge.

Limits

What the tradition cannot do.

• It cannot make an arrangement good: consent establishes permissibility, and a fully consented arrangement can still be unkind, unwise, or exploitative in every sense but the one this tradition measures.
• It cannot verify itself from outside: whether a yes was informed and voluntary is largely known to the parties, which is why third-party judgments about consent are so often wrong in both directions.
• It cannot handle constitutive dependence: infants, the seriously ill, and the deeply entangled are exactly the cases its machinery handles worst, which is care ethics' opening.
• It cannot substitute for structure: where refusal is expensive because of arrangements rather than persons, the tradition can name the defect and not repair it.

Criticisms

Standing objections, at strength.

• That consent launders coercion: agreements made under material necessity satisfy the criteria and reproduce the domination the criteria were meant to prevent.
• That informed consent has become paperwork: in practice the doctrine often functions as institutional liability management rather than as respect for the person signing.
• That the autonomous chooser is a fiction: the self who consents is formed by the relationships and conditions the model treats as external.
• That it individualizes: framing every question as bilateral agreement obscures the collective arrangements that set what the parties can agree about.

Common misreadings

Four.

• Consent as a shield: obtaining agreement in order to transfer responsibility, which inverts a doctrine designed to protect the agreeing party.
• One-time consent: treating an earlier yes as standing, when revocability is one of the tradition's four conditions.
• Consent talk in the wrong register: applying transactional vocabulary to intimate life so thoroughly that the relationship becomes a series of authorizations — the risk care ethics names.
• Third-party certification: declaring from outside that someone consented or did not, which the tradition's own epistemics do not license.

What remains outside this idea

The boundary.

• That an agreement was free: voluntariness is a condition the tradition specifies and cannot observe from outside.
• That a consented act was good: permissibility and value are different questions, and only the first is in scope.
• That anyone in this record consented to anything: the tradition is cited here for the structure of conduct claims, and no reading of documented conduct establishes what passed between people.
