dear alex,

u are interested in the unknown unknowns. and u r an internet addict. this is an absolute discrepancy!

let my try to explain this: it is true, that we find in net sometimes things, we want to know (known unknowns). And sure we mainly find things, we don't know, that we want to know them. This is great, but these things are not real unknown unknowns. I am total complete with you up to this point.

I am wondering, why you waste most of your time in the inet, there are no real unknown unknowns. I know your reply: “why r u still smoking?”… (please stop this boring topic.).

And u r so wrong with your sentence: “And each year we discover a few more…”. It is just opposite: each year we forgot a few more of those unknown unknowns, kids knows much more about them than u and me.

my university professor of philosophy told me, that is the reason, why socrates said “ Ich weiss, dass ich nichts weiss”, when he was old. But he (the prof.) was wrong, too.

i am sure, socrates just wanted to calm down his wife Xanthippe.
