Making The Case That Voynich Is A Hoax

DeadVulcan writes "The Voynich Manuscript, a mysterious book of uncertain age, is widely believed to be written either in an unknown language or a long-lost encryption scheme. Nature reports that computer scientist Gordon Rugg has demonstrated that it's possible to generate a text like the Voynich manuscript -- containing language-like regularities, despite being potentially meaningless -- using cryptographic techniques of the time. This lends some support to those who claim that the book is a hoax."

    ...but it's another thing to prove it.

    Anyone can say anything is a hoax but it takes scientific evidence - actual empirical data - to prove such a claim.

    For example, people once believed that the Earth was flat (some people still do) but the circumnavigation of the globe by explorers such as Magellan, lunar exclipses, etc provide evidence to the contrary.

    Saying that just because something could be a hoax then it is a hoax is just plain stupid. Like Fermat's Last Theorem, it may be many years before Voynich is proved to be geniune or accurate, but the absence of proof of the former doesn't provide proof of the latter. Remember, even though TLF has been proved, we still don't have the "simple proof" that Fermat himself discovered.

    Saying that the manuscript is more likely to be a hoax than not just because computer scientists have theorised that it could have been faked in the 16th century is like a 25th century scholar saying that the Wright Brothers flight, the atomic bomb and the Apollo missions are more likely to be hoaxes than not just because they could have been faked with 20th century technology.

      That's because he almost certainly didn't discover one.

      Fermat was known for making some pretty bone-headed mistakes. Also, in his future writings he posed challenges to prove FLT for the case of n=3 or n=4, but never for general n>2. If he had found a truly elegant proof of the general case, and believed it was true, why not pose the general challenge?

      I think what you're trying to get at is the inherent difficulty of "proving a negative". It's always much easier to prove an affirmative (which inherently contradicts the position to be disproved). Hence, sailing around the world to proves that it's round, and therefore not flat.

      However, the article offers speculation, not claims of proof/disproof.

      I don't see anything unreasonable in the claim that the manuscript might be a hoax; reasonable observers will note that this is not actual proof.

      In the meantime, speculation (within the realm of reason) that something could be hoax may suggest to these/other researchers paths of approaching the manuscript which eventually lead to its proof/disproof.

      This is how the scentific method is supposed to work -exploration of multiple paths moving progressing (hopefully) towards deeper insight.

    The 'true' examples of lost written languages/cyphers (do a google search) are mysteries because there exist few examples of brief length usually bereft of context (of grammar, history, linguistic evolution etc.).

    The sheer volume of the Voynich manuscript, plus its origin in relatively modern Europe is what makes it so interesting to amateur cryptographers.

      I doubt it. How many possible mappings are there between strings of characters and meanings? And even with plausible interpretations of the pictures (e.g., a herbarium), the number of things that might be said in that context is for all purposes unbounded:

      xyz =?= "this soothes the throbbing toe"
      xyz =?= "this is very poisonous"
      xyz =?= "this grows only in Ys"
      xyz =?= "I learned this from my grandmother" ...
      Surely it will never be deciphered if it is in an unknown language.

      > Champolion cracked the Rosetta stone with much much less.

      Actually, he had the benefit of a parallel text.

      In the absence of a parallel text, this will only be decyphered the way Linear B was: after a rigorous analysis of the patterns in the text, and a much tighter context (essentially lists of <picture,name,number> tuples), it was noticed that some very obvious translations ("man" and "woman", or such) fit the inflectional pattern of a language historically spoken in the region where the texts were found, and that simple mapping could be extended to other obvious <picture,name> pairs without introducing inconsistencies.

      I suppose it's possible that something similar could be done with the manuscript, but IMO only if there are some clearly labeled images that give tight enough a context to guess the specific word being used. And then some luck, because somebody has to recognize some language-specific patterns (such as the Greek masculine/feminine inflectional suffixes). And of course, more luck in what language it happens to be: Linear B might never have been deciphered if Greek didn't use gender-based patterns in its noun declensions.

      If it happens to be written in some unknown language, IMO it will never be deciphered.

      I think that this is an interesting curiosity but possibly a sad one for our age. It's hard to find people with heavy skills in dead languages nowadays.

      On a more discouraging note, once you throw encryption into the picture and add it to an unknown(?) inflected language, you see that the problem will require the assembly of rare intellectual resources to even adequately define the problem. Talking about human sense is one thing, finding humans capable of applying the sense could well be problematic.

    No actually "evidence" THIS broad lends no weight whatsoever. I saw this wholeheartedly as someone who has never even heard of the particular manuscript in question.

    Here is what I know, partly assuming what you've said is accurate. Nobody knows when the manuscript was produced, the only evidence that indicates it's existance at a particular point may be suspect (although this is the case with much of the dates we've fixed for events in history and even the basis for several things we believe happened to the degree we call and teach them as facts). Yet this discovery claims at the time the manuscript was produced it was possible to produce fake meaningless gibberish that appears to have meaning.

    Am I the only one who finds a problem with that in itself? How can you claim something was possible at the creation date when you don't know the creation date?

    Next, giving that magically the date looked into did happen to coincide with the creation date that nobody knows. How exactly does a process being theoretically possible at a date get considered as evidence that is what was done in a particular instance?

    Example, my house catches fire. Firefighters are unable to determine the source. The insurance company denies my claim on the grounds that the technology existed to rub two sticks together to generate heat and produce fire.

    I wouldn't even call that circumstantial evidence. That isn't EVIDENCE at all. Hell if there were two sticks in the lawn right under the tree, then it would become the most ridiculous circumstantial evidence that should obviously be tossed aside. But it would be the sticks that are the evidence there, not the fact that it's possible to create fire by rubbing two sticks together and the technology existed at the time. However there isn't even that much here.

Furthermore the person selling it to the first known possessor was a forger. Yes not all feature are repdroduced. But this is a step forward.

    The point of a hoax, in my opinion, would most likely have been financial gain.

    The manuscript was produced in a time when alchemy was the only science in town. Knowledge of herbal cures would've been a goldmine during that period, and studies to discover how to turn base metals into gold were the arms race of its day. Given that alchemist commonly encrypted their notes, this manuscript would've made a tempting purchase.

    One overlooked thought is the amount of effort that went into encryption and decryption at the time. It's possible the manuscript was designed to intrigue the political masters who would then throw all of their decryption resources at the manuscript, at the expense of apparantly more mundane, though more important, documents and cryptographic research being ignored.

Do you have some alternative code that stands up better to scrutiny?

    Also, at the time the books in the bible were written, accurate transcription wasn't considered nearly as important as it is today. The stories were part of an oral tradition anyway, and would have evolved in the telling before ever being committed to paper. Early scribes were aware of this and would not have thought twice about "correcting" parts of the story that didn't, to them, seem to be right.
