3.2.1 - Issues for Kantian ethics

The Evaluation Problem

Kantian ethics is attractive because it promises a morality that does not depend on luck, social approval, personal preference or the amount of happiness an action happens to produce. The worry is that this strength may become a weakness. If morality is about duty and rational consistency, can it deal with messy cases where duties collide, outcomes are terrible, or loving motives seem morally important?

The key is to keep Kant's deontological vocabulary in view. A deontological theory judges morality primarily by duty, principles and the kind of will expressed in action, not by total consequences.

This means that Kant can separate three questions which everyday moral thinking often runs together:

1. Did the action produce good consequences?
2. Was the action right, meaning permitted or required by duty?
3. Did the action have moral worth, meaning was it done from duty?

The issues in this lesson press on those separations. The critic says Kant separates them too sharply. The defender says that without the separation, morality becomes hostage to luck, calculation or desire.

Kantian baseline reconstruction:

1. P1: Moral value must be grounded in something under the rational agent's control.
2. P2: Consequences are not fully under the agent's control.
3. P3: The maxim and motive of the will are under rational assessment.
4. Therefore, C: The core moral value of an action is grounded in whether the will acts from duty on a permissible maxim, not in the outcome alone.

Hidden assumption: morality should assess agents as rational choosers, not merely as producers of effects.
Inference type: conceptual and practical reasoning.
Main pressure point: whether consequences and non-duty motives can be sidelined without distorting moral life.

Clashing Duties

A clashing duty is an apparent case where two moral requirements pull in different directions. A familiar example is a duty not to lie and a duty to protect an innocent person. If telling the truth helps a violent person find the victim, ordinary moral judgement says the duty to protect may override the duty not to lie. Kantian ethics looks exposed if it treats duties as exceptionless.

The objection is not just that hard cases exist. It is that Kant's system seems to generate impossible demands: do not lie, but also protect persons; keep promises, but also prevent serious harm; respect one person's agency, but also respect another's.

Clashing duties objection:

1. P1: A usable moral theory must give coherent guidance when duties appear to conflict.
2. P2: Kantian ethics treats at least some duties as strict duties grounded in the categorical imperative.
3. P3: Real cases can appear to require violating one strict duty in order to fulfil another.
4. Therefore, C: Kantian ethics either gives impossible guidance or ignores morally relevant features of the case.

Hidden assumption: genuine moral duties can conflict in a way that requires one duty to override another.
Inference type: practical objection from cases.
Main pressure point: whether the conflict is genuine or only apparent.

A Kantian reply is to deny that there can be genuine conflicts between true duties. If moral law is rational, it cannot command both an action and its opposite in the same circumstances. What looks like a clash may be caused by a crude description of the duties. The defender can distinguish:

The reply has force because it protects Kant from the charge that his ethics is a pile of isolated rules. Duties are meant to be generated by one rational moral law. Still, a residual issue remains: in urgent cases, refusing to lie may look like a technical escape rather than a morally adequate response. The critic can argue that a theory which tells the agent to preserve moral purity while foreseeable harm occurs has lost grip on what right action requires.

Universalisability Worries

The test faces a two-sided worry:

The first worry is about false positives. For example, the maxim I will tie my left shoe before my right can be universalised, but it is not therefore morally admirable. More seriously, a carefully self-serving maxim might be made narrow enough to pass a test if the agent builds in unusual details.

The second worry is about false negatives. Suppose someone adopts the maxim I will try to win this race. Not everyone can win the race, but competitive sport is not therefore immoral. Or suppose someone chooses a rare career that not everyone could choose without society collapsing. The surface description cannot be universalised in a crude everyone does the same thing sense, but that does not show the person has acted wrongly.

Universalisability objection:

1. P1: A moral test should sort morally permissible from impermissible maxims.
2. P2: Some universalisable maxims are morally trivial or not distinctly moral.
3. P3: Some apparently non-universalisable maxims are not immoral.
4. Therefore, C: Universalisability is either too weak, too strong, or too dependent on how maxims are formulated.

Hidden assumption: the universalisation test should be able to classify maxims without needing extra moral judgement.
Inference type: conceptual objection using counterexamples.
Main pressure point: whether the examples attack Kant's actual test or only a simplified classroom version of it.

A Kantian reply starts by clarifying the test. Kant is not asking what would happen if everyone copied the same outward behaviour. He is asking whether the agent's principle of action could be willed as law by rational agents without contradiction in conception or contradiction in will. The maxim I will try to win by competing fairly need not imply everyone wins; it implies everyone may compete under fair rules. The maxim I will lie when convenient fails because it undermines the practice of truthful assurance that the maxim itself needs.

The reply also says that passing the universalisation test does not automatically make an action morally heroic. It may show that a maxim is permissible, not that it is a duty or that the action has moral worth. Tying one's shoe in a harmless order can be morally neutral.

The residual issue is maxim formulation. If the maxim is described too broadly, innocent actions fail. If it is described too narrowly, dubious actions may pass. Kantian ethics therefore needs disciplined judgement about what the agent's real principle is. That is not fatal, but it means the test is not a mechanical shortcut.

Consequences and Moral Value

The consequence objection says that Kant gets moral value in the wrong place. If an action predictably saves or ruins lives, surely that outcome matters to its moral value. The challenge is sharpest in cases where a truthful, promise-keeping or rule-respecting action leads to severe harm.

This objection can mean two different things:

Consequence-based objection:

1. P1: If foreseeable consequences are very good or very bad, they affect the moral value of the action.
2. P2: Kantian ethics does not make consequences the foundation of rightness or moral worth.
3. P3: Therefore, Kantian ethics can judge an action right or morally worthy even when it foreseeably produces disaster.
4. Therefore, C: Kantian ethics gives an implausible account of moral value.

Hidden assumption: moral value should track the actual or expected effects of action.
Inference type: practical and evaluative objection.
Main pressure point: whether moral value means rightness, moral worth, blameworthiness, or outcome-value.

Kant's strongest reply is not that consequences never matter. A Kantian agent must still understand the situation, choose effective means, and take the duty of beneficence seriously. If I have a duty to help, I must care whether my action really helps. Consequences matter in applying duties.

The Kantian denial is more specific: consequences do not determine the basic rightness of violating duty, and they do not create moral worth. A person who tries to save another from duty but fails through bad luck may still have acted with moral worth. A person who helps from selfish calculation and accidentally produces a good outcome has not thereby shown a good will.

The residual issue is that foreseeable harm seems morally different from mere bad luck. If an agent can easily predict that a duty-following action will cause serious harm, the critic will say the outcome is part of the moral description of the action, not an external accident. This is where Kantian ethics can look too clean for the world it is meant to guide.
