The Four Loves collects C.S. Lewis’s reflections on friendship, romance, family, and divine love. It was published as a book in 1960 and developed from a BBC radio series broadcast in 1958.
Lewis discusses four Greek terms: storge for affection, philia for friendship, eros for romantic or sexual love, and agape for selfless or charitable love. The categories are explanatory rather than rigid boxes, and Lewis acknowledges that real relationships can involve more than one kind of love.
The book is sometimes confused with Lewis’s wartime broadcasts or with The Weight of Glory, which is a collection of sermons and essays. The Four Loves is specifically organized around different forms of human and divine love.
