The Pilgrim's Regress is a book of allegorical fiction by C. S. Lewis. This 1933 novel was Lewis's first published work of prose fiction, and his third piece of work to be published and first after he converted to Christianity. It charts the progress of a fictional character named John through a philosophical landscape in search of the Island of his desire. Lewis described the novel to his publisher as "a kind of Bunyan up to date," in reference to John Bunyan's 1678 novel The Pilgrim's Progress, recast with the politics, ideologies, philosophy, and aesthetic principles of the early 20th century. As such, the character struggles with the modern phoniness, hypocrisy, and intellectual vacancy of the Christian church, Communism, Fascism, and various philosophical and artistic movements.
