Which C.S. Lewis book presents Christian moral teaching through four human loves?

The Four Loves presents C.S. Lewis’s Christian moral teaching through four human loves.

Published in 1960, The Four Loves develops ideas first presented in a series of BBC radio talks. Lewis discusses affection, friendship, erotic love, and charity, using the Greek terms storge, philia, eros, and agape to distinguish forms of attachment that English often groups under the single word love.

The book does not simply rank the loves as independent categories. Lewis examines how each can be generous and life-giving while also becoming possessive or distorted. He treats divine charity as the form of love that can transform the others rather than merely replacing them.

The work is distinct from Mere Christianity, which presents a broader case for Christian belief, and from The Allegory of Love, Lewis’s scholarly study of medieval literature. The Four Loves is both theological reflection and an accessible analysis of relationships.
