Really? I can't empathize with that. Every answer raises more questions. Mr. Kreider makes an interesting point about information before the internet, but I don't think the internet has killed mystery, and definitely not obscurity. This essay seems a bit of a nostalgic reflex to me. He needn't worry about kids. I'm sure if he asked some, they'd overwhelm him with obscure stuff he had never heard about. The quote: "Learning how to transform mere ignorance into mystery, simple not knowing into wonder, is a useful skill". bothers me a bit. We have plenty of ignorance. We are swimming in our own ignorance. I know nothing compared to what could be known. IMHO ignorance is not 'mere' or endangered. -It's most of what we've got.
I agree that every answer raises more questions and the "blah, blah blah" -REALLY bothered me but I am nostalgic for the days when my grandfather would reach for the dictionary/encyclopedias that he kept at arms reach to find out clues to the questions that came up at supper. Now, one of us just pulls out a smartphone. Having to piece together information was part of the pleasure. You are right, ignorance is not endangered but perhaps "wonder" is?
