What is the title of C.S. Lewis’s 1960 book examining four kinds of love?

C.S. Lewis’s 1960 book examining four kinds of love is The Four Loves.

The book developed from a series of BBC radio talks and discusses four Greek terms used to distinguish forms of affection: storge, philia, eros, and agape. Lewis examines family affection, friendship, romantic love, and charitable or self-giving love.

Lewis does not present the four categories as isolated boxes. He explores how human loves can be transformed, distorted, or deepened, and he places them within a Christian account of divine love.

The Four Loves is sometimes confused with Lewis’s earlier work The Allegory of Love, which is a scholarly study of medieval literature rather than a modern discussion of personal relationships. The titles sound similar but address very different subjects.
