Which Tolkien essay argues that fairy-stories can offer recovery, escape, and consolation?

The Tolkien essay that discusses recovery, escape, and consolation is On Fairy-Stories.

Tolkien developed the essay from a lecture delivered at the University of St Andrews in 1938. It was published in expanded form in 1947. The work examines what fairy-stories are, where they come from, and what they can do for readers.

Tolkien identifies recovery as a renewed view of familiar things, escape as a movement away from the limitations of ordinary life, and consolation as the emotional power of a happy ending. He also discusses the “eucatastrophe,” his term for a sudden turn toward joy.

On Fairy-Stories is often connected with Tolkien’s fiction, but it is a work of literary criticism rather than a Middle-earth narrative. The essay is especially important for understanding his theory of fantasy and his defense of imaginative literature.
