Whatever “it” is, C.S. Lewis had it. I keep coming to his books assuming at some point that I will be let down. So far, that has not happened. “The Four Loves” is an superb examination of how various types of love should work or be lived out. But he also shows those loves in all their twisted ugliness when they become perverted. This is one of the greatest assets of the book. He doesn’t just extol affection, friendship, eros, and charity, he shows how dangerous those loves can be. His second chapter where he discussed good and bad patriotism was invaluable.
