A person diagnosed with psychopathy can clearly articulate why harming others is wrong and recite moral rules accurately, yet consistently acts immorally and without remorse. How does moral sentimentalism best explain this pattern?
AThe person lacks the correct moral beliefs; better moral education would fix the behavior
BMoral rules require frequent reinforcement to remain action-guiding, which the person has not received
CMoral action requires affective responses like guilt, compassion, and empathy to motivate behavior; without them, moral knowledge lacks the motivational grip needed to act
DThe person's reasoning is subtly flawed even though they appear to articulate rules correctly
The psychopathy case is one of sentimentalism's strongest empirical arguments. Psychopaths demonstrate that knowing moral rules and being motivated to follow them are separable. Sentimentalism explains the gap: Hume argued that reason alone cannot motivate action — what bridges the gap from 'this causes suffering' to 'I should not do it' is a felt response. Without guilt, compassion, or empathy, moral propositions remain inert facts rather than action-guiding imperatives. The other options attribute the failure to cognitive or informational deficits, missing the distinctively motivational role that sentimentalism assigns to emotion.
Question 2 Multiple Choice
What is Hume's foundational argument for why emotions, not reason, must be the basis of moral motivation?
AEmotions are more reliable than reason because they are harder to manipulate
BReason can only tell us facts about the world; it cannot by itself make us care about or act on those facts — only sentiment bridges fact and motivation
CReason is too slow to guide action in real situations, so we must rely on immediate emotional responses
DMoral emotions are innate and therefore more fundamental than learned rational principles
Hume's argument is precise: reason is 'the slave of the passions.' Reason can establish that an action will cause suffering, but the inference from 'will cause suffering' to 'I should not do it' requires caring about suffering — which is a sentiment, not a logical step. A perfectly rational being that felt nothing would have no motivation to act on any moral conclusion. This is the is/ought distinction applied to motivation: reason operates on facts, sentiment provides the evaluative grip. Options A, C, and D miss this specific argument about the structure of motivation.
Question 3 True / False
On a sentimentalist account, emotions like guilt and compassion are partly constitutive of moral recognition — not merely reactions that follow after a prior rational verdict of wrongdoing.
TTrue
FFalse
Answer: True
This is the strong sentimentalist thesis: feeling guilty is not a response to independently recognizing you did wrong — it is partly what recognizing wrongdoing consists in, at least at the level of practical moral life. Similarly, the felt pull of compassion is not added to a neutral recognition of suffering; it is part of how you access the moral significance of another's suffering at all. Moral education, on this view, is primarily emotional formation — cultivating the capacity to feel appropriately — not merely teaching propositional rules.
Question 4 True / False
Sentimentalism implies that any emotional response that feels genuine is a reliable guide to moral truth, making emotional calibration unnecessary.
TTrue
FFalse
Answer: False
This is the central challenge to sentimentalism and a common misconception. History is full of cases where people felt genuine, sincere moral indignation directed at innocent people, or compassion structured by in-group bias that excluded outsiders. Sentimentalists do not accept raw emotion as authoritative. They typically invoke the standard of a 'calibrated' or 'informed' sentiment — what an ideally situated observer with full information, no bias, and full imaginative engagement with all affected parties would feel. Moral progress, on this view, involves educating and refining our emotional responses, not abandoning scrutiny.
Question 5 Short Answer
How do sentimentalists respond to the objection that emotions can clearly go wrong — for example, historical cases of righteous indignation directed at entirely innocent people?
Think about your answer, then reveal below.
Model answer: Sentimentalists typically appeal to the notion of a calibrated or informed sentiment — the emotional response of an ideally situated observer who has full factual information, is free from distorting biases (in-group favoritism, fear, self-interest), and imaginatively engages with the perspectives of all affected parties. Raw emotion is not the standard; refined, reflective emotion is. On this view, moral progress consists in educating and correcting our emotional responses — not overriding them with pure reason, but cultivating them to track morally relevant features more accurately. The fact that emotions can go wrong does not show they are irrelevant to morality; it shows that emotional moral education is a genuine and ongoing task.
This response preserves the sentimentalist insight (emotions are foundational and motivationally necessary) while acknowledging that unreflective emotion is not authoritative. The key move is distinguishing actual emotional responses from idealized or calibrated ones, making emotional accuracy an achievable standard rather than assuming emotions are infallible.
