René Girard in Wanting:

“Humans don’t desire anything independently. Human desire is mimetic – we imitate what other people want. This affects the way we choose partners, friends, careers, clothes, and vacation destinations. Mimetic desire is responsible for the formation of our very identities. It explains the enduring relevancy of Shakespeare’s plays, why Peter Thiel decided to be the first investor in Facebook, and why our world is growing more divided as it becomes more connected.”
