Gulliver's Travels by Jonathan Swift follows Lemuel Gulliver, a ship's surgeon who embarks on a series of fantastical journeys. After a shipwreck, he finds himself in Lilliput, where he is a giant among tiny people. He later visits Brobdingnag, where he is a tiny man among giants. Gulliver also explores the floating island of Laputa and the land of the Houyhnhnms, intelligent horses who live by reason. Through these adventures, Swift critiques human nature, politics, and society, exposing the absurdities of his time.
