I've always liked Neal Stephenson's take, from "The Diamond Age": http://steveedney.wordpress.com/2006/11/08/hypocrisy-relativ...

(Note: that was just the first link I found, I'm not trying to start a debate about the rest of the blog post)

I like Stephenson's distinction as well, but have often found it difficult to get other people to understand it. Regardless, thanks for posting the link. It prompted me to buy a first edition of The Diamond Age to replace my exceedingly battered paperback. The Kindle edition would probably be more practical, but it's a book that belongs on a bookshelf!
