Bill's argument is pretty simple, if there were no plates, then Joseph must have been a liar. If we can show Joseph wasn't a liar, then there must have been plates.William Hamblin wrote:
1. Joseph Smith claimed to have had possession of golden plates written by the Nephites, and to have been visited by Moroni, a resurrected Nephite.
2. If the Book of Mormon is not an ancient document, there were no Nephites.
3. If there were no Nephites, there were no golden plates written by Nephites; and there was no Nephite named Moroni.
4. If there was no Moroni and no golden plates, then Joseph did not tell the truth when he claimed to possess and translate these nonexistent plates, and to have been visited by a resurrected man.
5. Hence, Joseph was either lying (he knew there were no plates or angelic visitations, but was trying to convince others that there were), or he was insane or deluded (he believed there were golden plates and angelic visitations which in fact did not exist).
The case against the Inspired Fiction theory can be elucidated with this simple question, which proponents of the Inspired Fiction theory must answer: if the Book of Mormon isn’t historical, then was Joseph Smith a deliberate liar when he said he had golden plates, and was visited by an ancient Nephite prophet, or was he merely delusional? Or was he perhaps a sincere liar, in that he came to believe in his own delusions? To these interrogatories a follow-up question may be asked: why would God choose a liar or a lunatic to bring about the Restoration? As Hamblin remarks,
If [those who read the Book of Mormon as inspired fiction] wish to maintain that the Book of Mormon is not an ancient document, but that Joseph Smith was somehow still a prophet, they must present some cogent explanation for Joseph’s wild claims of possessing nonexistent golden plates and being visited by nonexistent angels.
Unfortunately, since 1994 when Bill published this argument, the Internet has brought to light all of the myriad lies Joseph Smith told throughout his life. Faithful Mormons like Bill are stuck having to answer to us, the skeptics, "why would God choose a liar to bring about the Restoration?"
Why would God choose a man who decided to have a mock sealing ceremony in front of Emma? If he would do that to his own wife, why wouldn't he lie to strangers when creating the Book of Mormon?
