Duties and rights: what you owe regardless of outcome
Duty-based theories examine moral obligations and limits on how people may be treated. Compare Kant's strict duties with Ross's account of competing duties, including respect for people's choices.
What a learner can do afterwards
- State the duty-based claim and apply it to the same case used for consequences
- Explain what it means to treat someone only as a means, with an example
- Give a case where duties conflict and explain how Ross weighs them, noting that duty-based theories differ

Deontology judges actions by moral duties, not solely by results. A duty can limit what you may do to gain a benefit. Duty-based theories differ about exceptions and conflicts. Kant treats moral duties as binding despite a tempting payoff. He also gives unconditional worth to a good will: acting from duty has worth that does not depend on success.
Kant says to treat people as ends in themselves, never merely as means. Honest cooperation can help your goals while respecting another person's choices. Taking someone's wallet for charity instead takes their property without agreement. Deception can block informed choice. Consent matters because people should have a say in their involvement. Agreement alone does not cancel every other moral duty.
Kant's universal-law test asks whether you could consistently will everyone to follow your rule for acting. Suppose you borrow a charger by promising to return it while planning to keep it. This rule relies on trust in promises. If everyone made such false promises, that trust would be undermined. Kant argues that the rule defeats the practice it relies on. Asking whether most people approve is a different test.
The consequences lesson considers framing an innocent person to stop a riot and save twenty lives. Put this choice in your own words, even if you have not read that lesson. A results-only argument points to the lives saved. A duty-based objection asks whether framing the person violates a moral limit. Kant's strict approach rejects using that person merely to secure the benefit.
Ross treats several duties as genuine moral reasons that can compete. A promise to call a friend may conflict with helping an injured stranger. He uses the facts to judge which duty is weightiest in that situation. Urgent help can outweigh keeping the appointment. The promise still mattered, so explaining the delay and apologizing may remain appropriate. Duties need not all be exceptionless.
Duty conflicts challenge a theory to explain what to do. Ross offers judgment about the circumstances rather than a fixed ranking for every case. People may still disagree about the relevant facts or which duty is weightiest. This is a limitation to assess, not proof that duty-based theories have no answer. Nor does every duty-based theory ignore consequences.
Duties can limit the pursuit of better results. Kant stresses strict moral limits; Ross weighs competing duties using the circumstances.

Comparing moral reasons
Compare moral theories using the same stated facts. Otherwise, an apparent disagreement might come from changing the example.
Consider a proposal to frame an innocent person to stop a riot. Identify the expected benefit and the action proposed to obtain it. A results-only argument assesses what follows. A duty-based objection asks whether falsely blaming the person is a permitted way to seek that benefit.
Explaining the objection does not require assuming that every duty-based theory answers every difficult case alike. Some defend strict limits. Others recognize competing duties whose weight depends on the circumstances.
When assessing an answer, ask what reasons support it and how those reasons apply to this case. A clear verdict still needs an explanation. Disagreement can concern either the facts or the moral reasons.
A duty can matter without deciding the case
A promise gives you a reason to do what you said. It does not follow that every duty-based philosopher treats every promise as exceptionless.
Ross recognizes several duties that may pull toward different actions. If keeping a promise conflicts with urgent help, the circumstances matter to deciding which duty takes priority. Helping can be required without making the promise worthless.
That distinction explains why an apology can still be appropriate. You can acknowledge the missed commitment while maintaining that the emergency justified your decision. The apology does not mean that you should have ignored the emergency.
Ross's approach differs from treating each duty as an absolute command. It also leaves room for disagreement: people may assess the facts differently or disagree about which duty carries greater weight.
Trust and informed choice
A false promise can work because another person believes you intend to keep it. Kant asks what happens to the rule for acting when you consider it as a rule for everyone. He argues that universal false promising undermines the trust on which the action depends.
This test concerns consistency. It is not a vote on whether a rule is popular, nor a count of how many people might benefit.
Kant's account also directs attention to the person receiving the promise. Deception can withhold information needed for an informed choice. Honest cooperation can help your purposes without reducing another person to a tool.
Consent therefore matters to how people are involved. It does not follow that agreement settles every other moral concern. A plan can respect someone's choice and still require assessment against other duties.
