Which rule did Gulliver agree to that he found dishonorable?

Gulliver's sense of honor is evident throughout his adventures in Lilliput, particularly regarding his interactions with the society he finds himself in. The rule concerning helping the workmen is seen as dishonorable by Gulliver because it contradicts the values of his integrity and personal autonomy. He values hard work and honesty, and by agreeing to assist in a task that he feels should be undertaken by the Lilliputians themselves, he feels he is being exploited rather than engaged as a worthy ally. This situation illustrates his struggle between adhering to Lilliputian customs and maintaining his sense of dignity and moral code, ultimately leading him to feel that this requirement diminishes his honor.

In contrast, the rules about not moving freely, reporting to a commander, and speaking only Lilliputian, while restrictive, do not carry the same immediate conflict with Gulliver's personal values. Rather, they reflect the limitations imposed on him as a visitor in a foreign land and highlight the dynamics of power rather than the integrity of his character. Thus, the expectation to assist the workmen strikes Gulliver as particularly unjust and dishonorable, emphasizing the tension between his outsider perspective and the local customs.
