Strange that in his list of possible ways the text could have been created he doesn't mention either the artificial language hypothesis or the exotic natural language hypothesis, although he does mention "codebook" and "unknown script".
He also says that Rugg's proposed method "is consistent with 15th century knowledge", even though the Cardan grille wasn't invented until the 16th century (as far as we know).
Then he says "If Gordon (or somebody else) can name a set of tables and grilles (and maybe some additional instructions) that produce exactly a paragraph from the Voynich manuscript, the debate can be finished." But of course this is not true, since it's trivial to construct such a table and grille for any text. An example can be found here: You are not allowed to view links. Register or Login to view.
