"If you're ethnocentric, does your culture include a folk dance acknowledging the limitations of your outlook? Is there a beeper that goes off when you get too technocentric? If you're iconocentric, where's the visual image that's going to tell you that you are?"
I'll tell you who's saying that and what he's talking about after you bandy the question around a while.
ADDED: The quote is from "Alphabet Juice," by Roy Blount Jr., and he's talking about the word "logocentric."
