Which C.S. Lewis work presents four kinds of love, including affection and friendship?

The Four Loves presents four kinds of love, including affection and friendship.

C.S. Lewis developed The Four Loves from a BBC radio series broadcast in 1958. The resulting book, published in 1960, examines four Greek terms used to describe different forms of love: storge, philia, eros, and agape. Lewis discusses family affection, friendship, romantic or sexual love, and charitable or self-giving love.

The work is both philosophical and theological. Lewis does not simply rank the four categories as unrelated emotions; he considers how human love can be distorted and how divine love relates to them. His examples draw on literature, ordinary relationships, and Christian thought.

The Four Loves is distinct from Mere Christianity, which grew from wartime broadcasts about Christian belief. It is also different from Lewis’s memoir Surprised by Joy, which focuses on his intellectual and spiritual development.
