What is Gulliver's primary role in the societies he visits?

Gulliver's primary role in the societies he visits is that of a critic of human nature. Throughout his journeys, he encounters various civilizations that highlight different aspects of society and human behavior. His observations and experiences allow him to reflect on the vices and follies of humanity, often using satire to point out moral and social issues.

For instance, in Lilliput, he confronts the absurdities of political conflicts and power struggles, while in Brobdingnag, he is made to reflect on the limitations and flaws of his own society from the perspective of giants. Similarly, his encounters with the Houyhnbnms and Yahoos showcase the contrast between reason and barbarism, prompting critical thought about what it means to be human.

This role as a critic emphasizes Swift's satirical objectives, enabling readers to engage deeply with themes of morality, governance, and the human condition. By serving as a lens through which these critiques are delivered, Gulliver not only navigates through various cultures but also prompts readers to reflect on their own society.
