Who are we attracted to? Who do we love? And why? And who loves us? And why? Attraction and love are a mystery, but Wendy Paris’s article “The Laws of Attraction” is an excellent review. I would like to follow up and discuss the two most common theories of attraction. They are, as we might expect, contradictory. These are the “Opposites Attract” theory (a complementary theory), and they often do; and the “Birds of a Feather Flock Together” theory (a mirror or clone theory), and they often do.
