Serendipities: Language and Lunacy is a 1998 collection of essays by Umberto Eco. Dealing with the history of linguistics and Early Modern concepts of a perfect language, the material in the book overlaps with La ricerca della lingua perfetta. An iconoclastic, dazzlingly erudite and witty demonstration, by one of the world's most brilliant thinkers, of how myths and lunacies can produce historical developments of no small significance.
