What was the title of C.S. Lewis’s 1960 book about types of love?

C.S. Lewis’s 1960 book about types of love is The Four Loves.

The Four Loves developed from a BBC radio talk series and was published as a book in 1960. Lewis examines four Greek terms often used to distinguish kinds of affection: storge, philia, eros, and agape. He discusses natural affection, friendship, romantic love, and self-giving love.

Lewis does not present the four categories as isolated compartments. His discussion considers how human loves can be generous, vulnerable, limited, or distorted when treated as ultimate. He argues that affection and friendship are valuable forms of love, while also emphasizing the Christian concept of divine love.

The book is sometimes confused with The Great Divorce or Mere Christianity because all three address Christian ideas for a broad audience. The Four Loves is specifically organized around the classification and moral examination of love, making its title a direct summary of its central structure.
