What cultural aspects of Brobdingnag does Gulliver struggle to comprehend?

Gulliver's struggle to comprehend the cultural aspects of Brobdingnag mainly revolves around their social customs and views on morality. In Brobdingnag, the people live according to a set of ethical principles and values that differ significantly from those of Gulliver’s own society. This includes their understanding of virtue, justice, and the role of government, which he finds difficult to reconcile with the values he is accustomed to in England.

Throughout his interactions with the Brobdingnagians, Gulliver becomes acutely aware that their societal norms place a strong emphasis on the importance of honesty and integrity, leading him to reflect critically on the moral state of his own nation. This cultural encounter highlights the theme of perspective and the relative nature of morality, showcasing how Gulliver's bewilderment stems not just from the size of the Brobdingnagians, but also from their fundamentally different approach to ethics and social organization.

While the other aspects such as technological advancements or forms of entertainment could cause some confusion, it is primarily the profound difference in moral viewpoints that leaves a lasting impact on Gulliver and prompts much of his internal conflict during his stay in Brobdingnag.
