More than sixty year ago C. S. Lewis wrote a book called The Four Loves. Ever since, his framework has proven a reliable and popular paradigm for thinking about different aspects or modes of love. The terms he uses are storge, eros, philia, and agape; we might loosely translate these as kinship, romance, friendship, and self-giving to and for the other. They denote the love that obtains between members of a family, between spouses in a marriage, between close friends, and between humans and God.
