What this dot point is asking
OCR Component 02 sets Kantian ethics as a deontological theory: morality is about duty and the rightness of acts, not their consequences. Immanuel Kant grounds it in reason, the good will and the categorical imperative. You study the good will and acting from duty, the three formulations of the categorical imperative, and the summum bonum with its postulates. The exam rewards explaining the system precisely and then evaluating whether duty-based, consequence-blind ethics is sound.
The answer
The good will and duty
Hypothetical and categorical imperatives
The three formulations
The summum bonum
Strengths and weaknesses
- Strengths: it secures human dignity and equality; it is consistent and rational; it does not let the majority sacrifice the individual.
- Weaknesses: it ignores consequences, giving the notorious result that one must tell the truth to a murderer asking where their victim is; duties conflict with no way to rank them; and it seems cold towards emotion, love and care, which many think central to morality.
Examples in context

Q1. "Kantian ethics is too rigid to be a useful guide to moral behaviour." Discuss. [40 marks]
- What the marker wants. An AO2 essay weighing the dignity and consistency of duty against the inquiring-murderer rigidity and conflicting duties, judging whether the theory is usable. AO1 out of 25, AO2 out of 15.
Q2. Assess whether Kant is right that morally good actions must be done from duty rather than inclination. [40 marks]
- Cue. Kant locates moral worth in acting from duty, not from feeling. Weigh this against the view that compassion and love are central to morality, and judge.

A 40-mark Component 02 essay on the six-level scheme (AO1 out of 25, AO2 out of 15). Explaining the theory earns AO1; the higher levels reward judging how good a guide it is.
Explain (AO1). For Kant the only unqualified good is a good will acting from duty, not inclination or consequences. The categorical imperative commands unconditionally: universalise your maxim; treat humanity as an end, never merely as a means; act as a legislator in a kingdom of ends. Morality is a priori and rational.
Evaluate (AO2). Strengths: it secures human dignity, equality and consistency, and grounds duty in reason. Weaknesses: it ignores consequences (the inquiring murderer at the door); duties can conflict with no way to rank them; it seems cold towards emotions and care.
Judge. A top answer decides whether the universalism that gives Kant its strength is also its fatal rigidity, and defends the verdict.
OCR H573/02 2020 (style)20 marksCritically assess Kant's claim that morality requires us to treat people as ends and never merely as means. (The full OCR tariff for this essay is 40 marks; the worked answer below is scaled to a 20-mark exemplar.)Show worked answer →
A levels-of-response essay testing AO1 understanding of the second formulation and AO2 evaluation of it.
Explain. Kant's formula of the end in itself forbids using a rational being merely as a tool for someone else's purpose; each person has intrinsic worth (dignity) as a rational, autonomous agent and must be treated accordingly. Slavery, deception and exploitation are wrong because they use people merely as means.
Evaluate. Strengths: it underwrites human rights and explains why exploitation is wrong without appeal to consequences. Weaknesses: ordinary life requires using people partly as means (paying a worker); "merely" is doing heavy work, and Kant gives little guidance when treating one person as an end harms another.
Judge. A high-level answer weighs whether the formula is a sound moral foundation or too abstract to resolve real conflicts, and reaches a justified conclusion.
