Jonathan Swift's Gulliver's Travels is a political and social satire published in 1726 consisting of four voyages undertaken by the protagonist Gulliver. Through these voyages, Swift satirizes various human failings such as pride, irrationality, and lack of reason through comparisons to societies that represent ideal versions of human behavior and abilities. The work criticizes aspects of English society and human nature more broadly, portraying humans as petty, gross, and driven by emotion over reason. It challenges readers to improve upon these failings in themselves and their societies.
