Thanks for taking the time to reply. I have been looking for the essay but am having no luck… if you know the title, or something else that would help me locate it please let me know You might be interested in this: It also deals with the relativity of knowledge, but from a vary different perspective.

I’d love to help but you must help an old woman out here as I am so embeded in cyberspace that I get lost.  Could you remind me of the essay in question?  I write blogs 5 days a week and juggle twitter, facebook and tumblir and write books.  Will look up the Harpers article but be kind and refresh my memory a little.  Helping and sharing is what I love to do!
