Could the Voynich Manuscript be a private educational system?

[Rafal]

Some interesting issues raised here.

What strikes me most is the contrast between the highly disciplined writing system and the relatively naive illustrations. The text appears systematic and internally consistent, while many drawings look almost childlike or non-professional.

I suppose we could all agree on that. Handwriting is much better than illustrations. But it doesn't mean that the artist was a child, only that he or she was inexperienced in drawing. You can for a laugh ask some your adult friends to draw a human or a horse and watch the results 

I also wonder whether the author could have been someone highly intelligent but outside formal academic structures, possibly even a woman with limited access to official education in the 15th century.

It is possible for me. This or just having only a brief contact with formal knowledge and education. I once suggested a link to goliards or clerici vagantes, "eternal students" who often got into some shady business and generally preffered a tavern to a library.

To me, the manuscript feels less like a hidden universal language and more like the internal operating system of a very unusual human mind.

Well, it's one of the perspectives. If you read these forums, you will discover another ones - pure hoax, Asian language, story told in pictures with unimportant text and so on.
