Chapter 28
When Duty Should Rule Your Heart
In what cases the sense of duty ought to be the sole principle of our conduct; and in what cases it ought to concur with other motives. Religion affords such strong motives to the practice of virtue, and guards us by such powerful restraints from the temptations of vice, that many have been led to suppose, that religious principles were the sole laudable motives of action.

"The general rules of almost all the virtues, the general rules which determine what are the offices of prudence, of charity, of generosity, of gratitude, of friendship, are in many respects loose and inaccurate, admit of many exceptions, and require so many modifications, that it is scarce possible to regulate our 229conduct entirely by a regard to them."
Context: Middle section where sympathy and propriety are tested.

Discussion Questions
This is not a test. Five prompts guide you through the chapter, from how it opens to how it closes, so you notice context and rhythm rather than facts to memorize. Sit with each question in your own words. When you see "One way to read it," treat it as a starting point, not the only answer.
- 1
How does Smith's opening discussion of sympathy frame the argument in 'When Duty Should Rule Your Heart'?
analysis • surfaceOne way to read it
One reading is that he sets the spectator's imagination as the test of propriety. The opening line about 'A benefactor thinks himself but ill requited, if the person upon whom' signals that moral approval begins in shared feeling, not in detached rules.
- 2
What middle development turns on the claim that 'The general rules of almost all the virtues, the general rules which determine what'?
analysis • mediumOne way to read it
Smith is tracing how spectators move from observation to judgment. The middle section shows that we approve passions when we can keep time with them and condemn them when imaginative substitution fails.
- 3
When have you seen a group misjudge someone's emotions because they could not simulate that person's situation?
application • mediumOne way to read it
Personal answer. The chapter suggests many 'overreactions' are proportion judgments made with incomplete imagination. Managers, clinicians, and family members often err by measuring others on their own emotional scale.
- 4
Near the close Smith stresses that 'As a person may act wrong by following a wrong sense of duty, so'. What social cost follows when spectators refuse that insight?
application • deepOne way to read it
Relationships fracture when people feel unseen in their passions. Smith warns that moral communities depend on shareable feeling; when sympathy fails, isolation and resentment replace trust even if no formal rule was broken.
- 5
After 'When Duty Should Rule Your Heart', what habit would you change in how quickly you call another person's feeling unreasonable?
reflection • deepOne way to read it
A strong takeaway is to separate 'I would not feel that' from 'they should not feel that.' Smith pushes readers to treat failed sympathy as an imagination problem first, which can slow harsh judgment without excusing harm.
Critical Thinking Exercise
Map Your Feeling vs. Duty Moments
Think about three recent situations where you had to choose between acting from genuine feeling or strict duty. For each situation, identify whether it involved positive or negative emotions, and whether the outcome required flexibility or rigid rules. Then evaluate whether you chose the right approach and what happened as a result.
Consider:
- •Notice whether you tend to default to duty when feeling would serve better, or vice versa
- •Pay attention to situations where someone else demanded the wrong approach from you
- •Consider how your choice affected the other person's trust and the relationship dynamic
Journaling Prompt
Write about a time when someone treated you with cold duty when you needed genuine warmth, or hot emotion when you needed principled fairness. How did it feel, and what did you learn about what you want to offer others?
