A discussion arose in our office which brought about remembrance of an old term used by William F. Buckley, Jr. — from his old National Review days — in his "Word of the Day." We can't find the term on the Interwebs, so we come to SE:ELU in hopes of enlightenment.
The definition, as we recall is:
"Being ignorant of something of which you have neither reason nor expectation to have any knowledge."
I'd really like a reference to Buckley's WotD if possible since it will be used frequently in my geek- and academic-heavy office!
