Whatever information the Voynich Manuscript contains, we know it was written by a human being in the not too distant past. So the author had the same sensory inputs as the rest of us; a cultural background that is recognizable, if not identical to our own; human emotions that drove him (or her) in exactly the same way they drive us. And yet he (or she) wrote a book we can’t decipher. If such a situation can occur with a member of our own species, what chance do we have of understanding a message from an ETC?
