Bertrand Russell wrote a stingingly sarcastic essay about the rise of self-centeredness.
Ignore fact and reason, live entirely in the world of your own
fantastic and myth-producing passions; do this whole-heartedly and with
conviction, and you will become one of the prophets of your age.
--From How to Become a Man of Genius
Russell's essay; are you self-centered? you can take a quiz to confirm.
