French sociologist Rene Girard said that all human conflicts are built around something called “mimetic desire.” Here’s how it works. Suppose two brothers are happily playing in their front yard. The older one grabs a toy soldier from their pile of toys and begins playing with it. The younger one immediately wants it—not because of its inherent worth, but simply because his brother has it. This makes the older brother want it even more, and before very long the two are engaged in a huge fist fight.
Luckily, though, the neighborhood whipping boy, Jerry, happens to walk by at that moment. Jerry wears glasses and is chubby. The two boys forget all about their argument and run off together to torment Jerry.
