Voynichese is a numeric cipher?

Sorry, Stolfi, that I'm writing this.

The degree of conviction increases the more one engages with a theory—that’s a typically human phenomenon.

The biggest problem with people is that they’re all so incredibly convinced of their convictions.

What’s weird, though, is that so many others are anything but convinced. Are they all stupid?

One thing’s for sure: you haven’t managed to convince the masses yet, and that would make me suspicious.

My main problem is that the SPS = SBJ but the rest of the words can't be mapped? Just a few cribs, as I understand it. Isn't that a problem?
