Homonym: Catch 22 (Paradox)
"Catch-22" is a satirical novel written by Joseph Heller, published in 1961. The story is set during World War II and follows the experiences of Captain John Yossarian, a U.S. Army Air Forces B-25 bombardier. The term "Catch-22" refers to a paradoxical rule that prevents soldiers from escaping dangerous situations, as they must be deemed insane to avoid flying combat missions, but if they request to be grounded, it proves their sanity.
The novel explores themes of bureaucracy, the absurdity of war, and the struggle for individual autonomy. It highlights the illogical nature of military regulations and the often futile attempts of characters to navigate a system that seems designed to trap them. "Catch-22" has become a cultural reference for any no-win situation or contradictory rule.
