What was the title of C.S. Lewis’s 1933 novel about a man’s spiritual journey?

C.S. Lewis’s 1933 novel about a man’s spiritual journey is The Pilgrim’s Regress. Its subtitle, An Allegorical Apology for Christianity, Reason and Romanticism, signals its allegorical design and intellectual concerns.

The central character, John, travels through a landscape representing competing philosophies, desires, and religious positions. The book was Lewis’s first published work after his return to Christianity, although its style and symbolism are more difficult than those of his later popular apologetic writing.

The title deliberately recalls John Bunyan’s The Pilgrim’s Progress, a classic Christian allegory. Lewis’s work is not a sequel to Bunyan’s book; it is a modern, highly personal response to the tradition of spiritual pilgrimage.

The novel is sometimes confused with Lewis’s later science-fiction trilogy because it also uses a journey structure. Its setting, however, is an allegorical landscape rather than the interplanetary worlds of Out of the Silent Planet and its successors.
