Which C.S. Lewis work examines four forms of love in its title?

The Four Loves examines four forms of love in C.S. Lewis’s book of that title. Published in 1960, it develops ideas first presented in a BBC radio series and discusses affection, friendship, erotic love, and charity.

Lewis uses Greek terms to distinguish the kinds of love: storge for affection, philia for friendship, eros for romantic or sexual love, and agape for charity or self-giving love. His discussion compares their strengths and dangers rather than treating them as isolated emotions. The book is both a work of Christian reflection and an accessible examination of human relationships.

The title can be confused with Lewis’s fictional works. Till We Have Faces is a myth-based novel, while The Great Divorce is a theological fantasy. The Four Loves is nonfiction and focuses directly on the classification and meaning of love.
