Ditto for Aristotle.
The Church also finished the rest of Homer's works too.
Going by your “expertise” of how literary works were derived from antiquity; Herodotus, Polybius, Thucydides (LOL), Hippocrates, Isaeus, Sextus Empiricus, etc... literary undertakings were all created from Church manuscripts, thus all forgeries in your view.
Do you have any idea how all these manuscripts are created and then put under historic review?
If you have proof Tacitus was a forgery, then you would be the toast of academia. Never heard of anyone proving this though.
In the end, it doesn’t matter if Plato wrote “The Republic”. It doesn’t matter if it was written by one person or re-written by several people. If we found out tomorrow that Shakespeare never existed, and that all those plays were written by Francis Bacon or Christopher Marlowe it wouldn’t change the importance of “MacBeth”. What matters is that we have the works and that they are brilliant commentaries on the human condition. The difference between the historical existence of Plato or Shakespeare and Jesus is that neither Plato nor Shakespeare ever make any claim to divinity. Their works don’t perpetuate centuries of violence, war and bloodshed. And, nobody ever committed genocide because some other group didn’t want to sit through “A Midsummer Night’s Dream”.
