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 http://tetw.tumblr.com/ask. You might be interested in this: http://www.harpers.org/media/pdf/dfw/HarpersMagazine-2001-04-0070913.pdf 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!
