"Not knowing", or changing one's mind.

[nickpelling]

I should perhaps add that I personally spend a lot of time trying to come up with ideas and hypotheses about the Voynich Manuscript that can (and hopefully in the future will) be tested. So I can confirm that this part of the research equation is at least possible.

However, I only wish that (a) it was more than just me trying to do this, and that (b) there had been any noticeable appetite for testing hypotheses.
