A person can reason flawlessly about ethical cases — correctly identifying duties, calculating consequences, and explaining moral rules. Yet they feel nothing when witnessing cruelty or injustice. According to the sentimentalist tradition, this person:
AHas complete moral knowledge and simply lacks the motivation to act on it
BLacks full moral understanding, because emotional response is constitutive of grasping moral salience — not separate from it
CIs a model rational moral agent, unaffected by the biases that distort emotional reasoners
DWould make better moral decisions than emotionally responsive people, since reason alone guides them
Hume's sentimentalist tradition holds that reason alone cannot produce motivation — only sentiment can move an agent. Someone who reasons correctly about ethics but feels nothing when confronted with cruelty doesn't merely lack a motivational add-on; they are missing the felt recognition that something *matters*, which is part of what moral understanding means. The 'sociopathic calculator' is not a successful moral reasoner — they represent a failure of moral cognition.
Question 2 Multiple Choice
Someone argues: 'Emotions should be excluded from ethical reasoning because they cause bias and cloud judgment.' What is the strongest response to this view?
AThe view is correct — pure reason is sufficient for ethics and emotions only introduce error
BWhile emotions can distort (in-group bias, vivid-case sensitivity), they also direct attention to morally relevant features and motivate action; eliminating them would leave moral salience invisible
CEmotions are always reliable moral guides and should always override rational analysis
DEmotions only matter within virtue ethics; deontology and consequentialism can proceed without them
The insight is that emotions are not merely interference — they perform essential cognitive work, highlighting what matters morally and providing the motivational force behind moral behavior. Research on people with emotion-processing damage shows they can reason about cases but systematically fail to make normal moral decisions. The goal is not to eliminate emotion but to cultivate accurate, well-calibrated moral emotions through critical reflection.
Question 3 True / False
According to the sentimentalist tradition, someone who reasons about ethics correctly but feels no guilt, indignation, or compassion is missing something essential to full moral understanding.
TTrue
FFalse
Answer: True
This is the core sentimentalist claim: moral emotions are not mere accompaniments to moral reasoning but part of what constitutes moral understanding. Understanding that cruelty is wrong, in the morally significant sense, involves being *moved* by cruelty — not merely representing it correctly as a proposition. The emotionless calculator understands ethics the way a colorblind person understands wavelength tables: technically accurate but missing the thing itself.
Question 4 True / False
Because moral emotions like compassion and indignation can be biased (flowing more toward in-group members, triggered by vivid cases), they should be eliminated from moral reasoning mostly.
TTrue
FFalse
Answer: False
The appropriate response to emotional bias is not elimination but cultivation and correction. A mature moral psychology requires both the emotional responsiveness that makes morality motivationally alive *and* the critical reflection that corrects distortions. Eliminating emotion would remove the very faculty that makes moral salience visible, leaving only calculation with no felt sense of what matters.
Question 5 Short Answer
Why, according to the sentimentalist view, is a person who reasons flawlessly about ethics but feels nothing morally different from someone with full moral understanding?
Think about your answer, then reveal below.
Model answer: Because moral emotions are not just motivational add-ons to reasoning — they constitute part of the moral cognition itself. They direct attention to morally salient features, encode moral judgments (guilt tracks one's own failure, indignation tracks others' wrongdoing), and provide the motivation that reason alone cannot supply. Without appropriate emotional responses, the person lacks the felt recognition that something matters, which is what makes moral understanding genuinely moral.
Hume's point is that reason can determine what is true and what follows from what, but it cannot by itself generate care or motivation. Moral emotions do the work of making things matter — they are the difference between knowing abstractly that cruelty causes harm and actually being troubled by cruelty. The emotionless person has moral information but not full moral understanding.
