Living and learning...............

"One mark of genuine learning is a person's ability to live comfortably and intelligently with the fact that he can't possible know everything.  He feels no shame about the fact that he may be uninformed about a given subject, for he has substantial access to an answer if he really needs it, and he can evaluate the answer.  He won't lose himself in unfamiliar terrain where he may grab a the first intelligible answer and not necessarily the most competent one.  He knows what a blind alley looks like, and he doesn't clutter himself with facts beyond his needs."
-Norman Cousins, Human Options
