As I stated in my 2010 FAIR conference address:
Which is one of your favorite straw man arguments, while presenting it as if it is supposed to be a jewel of enlightenment.
Of course no one believes Joseph Smith engaged in an " academic" translation. Meaning, that he understood these languages and translated to English based on his knowledge of these languages. No one ever argued this. Ever.
What Will is trying to do however is argue that Joseph Smith never believed his English translations represented a literal translation of the ancient documents. All the evidence clearly points to the fact that he did believe this. He made it perfectly clear what he was doing and what he was translating. Relying on the translations of the JST and the Book of Mormon is just diversionary techniques that assume all translations are equal. They're not. Anyone remotely familiar with his method knows that he used the Gold Plates to translate the Book of Mormon. Yet, William has gone on record to say that the plates were not needed at all. The Nephites went through hell for 600 years to preserve and pass down a record that, in Will's view, was never really needed to begin with. This is how absurd his apologetic theory has become. He uses the JST as an example so he can say, "Look, this translation doesn't derive from any ancient Hebrew documents so maybe the Book of Abraham didn't either." Sure, but with the JST Joseph Smith never claimed to be translating biblical papyri either. He did claim to be able to translate Egyptian and reformed Egyptian from their source documents. "By revelation"? Yes, of course, but this doesn't change the fact that he took one character from language X and translated it to English.
It is a sad thing that after all these years, William is still pushing these easily refutable apologetic pieces. I just wish he'd commit them to publication for once.
