Which C.S. Lewis book collects his 1958 reflections on love?

The Four Loves collects C.S. Lewis’s reflections on love first published as a book in 1960.

The work grew out of a 1958 BBC radio series and examines four forms of love using Greek terms: affection, friendship, erotic love, and charity. Lewis discusses how these kinds of love can overlap while still having different characteristics and risks.

The Four Loves is not a novel or a simple list of romantic advice. It is a work of Christian apologetics and moral reflection, asking how human loves relate to self-giving love and to religious belief. Lewis’s treatment also draws on literary examples and observations about ordinary relationships.

Readers sometimes confuse this book with The Allegory of Love, his scholarly study of medieval literature, or with Till We Have Faces, a myth-inspired novel. The Four Loves belongs to Lewis’s nonfiction writing and is one of his clearest studies of human relationships.
