“Whom the gods wish to destroy,” writes Cyril Connolly, “they first call promising.” First published in 1938 and long out of print, Enemies of Promise, an “inquiry into the problem of how to write a book that lasts ten years,” tests the boundaries of criticism, journalism, and autobiography with the blistering prose that became Connolly’s trademark. Connolly here confronts the evils of domesticity, politics, drink, and advertising as well as novelists such as Joyce, Proust, Hemingway, and Faulkner in essays that remain fresh and penetrating to this day.
