"higher ignorance (a learned understanding that no matter how many truths we may accumulate, our knowledge falls infinitely short of the truth"

What's interesting to me is that so many of the people here discussing this tacitly seem one way or another to accept that there is some kind of ultimate 'truth' to be had (an idea I'd concur with). Of course, if there were no truth then all quests of knowledge and learning would be somewhat pointless. It would also be contradictory, since the absence of truth is falsehood. If everything were falsehood, then nothing we learn or know would be of any practical value. I'll have to think about that, myself. ;-)
