The Four Loves summarizes four kinds of human love--affection, friendship, erotic love, and the love of God. Masterful without being magisterial, this book's wise, gentle, candid reflections on the virtues and dangers of love draw on sources from Jane Austen to St. Augustine. The chapter on charity (love of God) may be the best thing Lewis ever wrote about Christianity.
The Four Loves by C. S. Lewis is a book everyone in their lifetime should read (once when you’re young and once when you’re old). Lewis explores the four different kinds of love, affection, friendship, eros, and charity. It is a Christian book so the talk of God does get a little overwhelming (for people who aren’t of that vicinity), but a fantastic read nonetheless.
