I don't think one can conclude Spalding's and Smith's were the same genre. Spalding was writing a historical account grounded in naturalism. Smith was writing a fantasy/religious account, in which in the storyline..angels and God intervene physically and according to Smith outside the storyline of the Book of Mormon they intervene physically in his life.
Naturalism and supernaturalism are larger sets, and therefore less meaningful, than the genre of Mound Builder history.
Smith did not need that discovery narrative, in fact it doesn't really mesh with the storyline capabilities of his characters. God helps him translate through miraculous means and the plates are not even necessary. Angels appear and physically take the plates away. If God and the angels have these powers there is absolutely no need to hide plates in the earth or to have Smith go dig them up. The plates were redundant to the storyline Smith presented to the world.
If you read the Book of Mormon, you would know that it ends with Moroni burying the plates, so an angel just handing the plates to Joseph Smith is not an option.
So when one critically evaluates what was claimed and the data ..it appears that Smith may have started out with a discovery narrative taken from Spalding but as time went on appreciated he had God, angels and magic on his side, so why bother with the plates ...what a nuisance they are, just say the angel took them away.
This makes no sense, mostly because it conflicts with Roger’s assertion that Joseph Smith didn’t have a discovery narrative that matched Spalding’s narrative until 1838. He’s arguing plagiarism. I’m arguing that the 1838 history is just a sanitized version of what he had been telling since 1823. He couldn’t keep the plates around because in either case they weren’t real.
The fact that there are very close similarities between Spalding's discovery narrative in MSCC and Smith's 1838 version.. does not in an of itself mean one was used for the other. But when you consider that fact in relation to other data, such as the fact that the Conneaut witnesses did not suggest the discovery narrative as a factor in why they thought Smith employed Spalding's MF and they likely were completely unaware of Smith's discovery narrative .. then the data that there are lots of similarities between Spalding's MSCC & Smith's discovery narrative gives added weight to the claim the witnesses made of recognizing Spalding's manuscript in the Book of Mormon. It increases the likelihood of their credibility because if Smith did use Spalding's MF..then that would explain where the idea for his discovery narrative came from. And when we consider as additional data that Smith did not need that discovery narrative given that he had God and angels involved with supernatural abilities to help him read off of a stone the ancient stories..that continues to build a picture that Smith likely was aware and used that discovery narrative from Spalding..before realizing it really wasn't necessary to his claims.
This also makes no sense. The witnesses’ testimonies are more credible because they didn’t mention the similarities between Spalding’s and Joseph Smith’s discovery narratives, even though according to you they didn’t know about Joseph Smith’s. This is strengthened further by Joseph Smith’s not needing a discovery narrative, but stupidly borrowed Spalding’s anyway, but then realized he didn’t need it so he dispensed with it. This is nonsense. He got rid of the plates long before writing his 1838 history. As I mentioned above, the discovery narrative was essential to his story. You are missing an important and obvious element of Joseph Smith’s method. It was to provide physical evidence for his claims—hence, the plates and witnesses. These plates were brought home from the hill in 1827, handed to Josiah Stowell, felt by the Smith family through a cloth covering, place in a box, then under hearth, later under the shed, then in a barrel of beans, taken to Harmony, moved by Emma while dusting, hidden in the woods, etc. The plates were important to Joseph Smith’s claims.
Spalding's MSCC would probably have not been the one Smith would have likely seen, he would have likely seen the one connected to MF. However MF being of the same genre and author would likely have had a similar discovery narrative.
The existence of such a MS is highly questionable, the contents even more so. As I have argued, the similarities in the discovery narratives are predictable given the limited choices. Joseph Smith didn’t need Spalding’s MS for his narrative, which he began giving in 1823.
