In my paper "The Book of Mormon as Literary Alchemy: Joseph’s Magnum Opus and the Philosopher’s Stone," I suggested that the "gold plates" that Joseph Smith had in his possession were not actually made of gold, and did not actually contain ancient historical records like Mormons traditionally think. But that doesn't mean that there were not "gold plates" which were a kind of "hidden treasure" that Joseph really did discover within himself, which was the source of real divine wisdom, "ancient wisdom," and which he taught could be found within all people as well.
