The Four Loves was published in 1960.
The Four Loves developed from a 1958 BBC radio series and was published as a book in 1960. Lewis examines four Greek terms commonly used to distinguish kinds of love: storge for affection, philia for friendship, eros for romantic love, and agape for self-giving charity.
Lewis does not treat the categories as sealed compartments. He explores how ordinary human loves can be generous and valuable while also becoming possessive or distorted. The book’s argument places human love in relation to divine love, which Lewis describes using the Christian concept of agape.
A Grief Observed is Lewis’s 1961 reflection on bereavement after Joy Davidman’s death. Till We Have Faces is a 1956 myth-based novel, and The Weight of Glory is a collection of essays and sermons.
