I don't know about complete imagination, because our imaginations are tied to that which we could possible know, that which we've been fed to think already. So we have to take from that which came previously to some extent. But on this point, if I read his point correctly, I'd say it's the exact opposite. Considering the story of Jesus its far more likely, after an evaluation, to say Jesus was a made up, thus mythical, haracter rather than a historical person.I think you can reasonably conclude there was a preacher named Jesus. Otherwise you have to assume the more improbable hypothesis that the Jesus character came out of complete imagination.
The below is mostly taken from On the Historicity of Jesus, ch. 5, pgs 229-234 with of my own comments (Carrier's words in the quote boxes):
From ancient stories there is a trend developed for defining a 'divine king' hero. Carrier calls this the Rank-Raglan hero-type. It is defined by these elements:
1. The hero's mother is a virgin.
2. His father is a king or the heir of a king.
3. The circumstances of his conception are unusual.
4. He is reputed to be the son of a god.
5. An attempt is made to kill him when he is a baby.
6. To escape which he is spirited away from those trying Old Testament kill him.
7. He is reared in a foreign country by one or more foster parents.
8. We are told nothing of his childhood.
9. On reaching manhood he returns to his future kingdom.
10. He is crowned, hailed or becomes king.
11. He reigns uneventfully (i.e., without wars or national catastrophe)
12. He prescribes laws.
13. He then loses favor with the gods or his subjects.
14. He is driven from the throne or city.
15. He meets with a mysterious death.
16. He dies atop a hill or high place.
17. His children, if any, do not succeed him.
18. His body turns up missing.
19. Yet he still has one or more holy sepulchres (in fact or fiction)
20. Before taking a throne or a wife, he battles and defeats a great adversary (such as a king, giant, dragon, or wild beast)
21. His parents are related to each other.
22. He marries a queen or princess related to his predecessor.
These are the top 15 on the list (scores in parentheses):
1. Oedipus (21)
2. Moses (20)
3. Jesus (20)
4. Theseus (19)
5. Dionysus (19)
6. Romulus (18)
7. Perseus (17)
8. Hercules (17)
9. Zeus (15)
10. Bellerophon (14)
11. Jason (14)
12. Osiris (14)
13. Pelops (13)
14. Asclepius (12)
15. Joseph [i,e., the son of Jacob](12)
To further note, it may be possible to score Jesus a 22 and thus make him the highest scoring figure on the list. But the last two elements would be too unknown, not mentioned in the gospels (even if later or previously believed). Thus, it could be, and likely is, Jesus was created to fit the motif of divine kings. It is, but one piece of data and details how it is far more likely that Jesus was a mythical person rather than a historical one.No known historical persons are on the list. Only mythical people ever got fitted to this hero-type. Yet every single one of them was regarded as a historical person and placed in history in narratives written about them.
Thanks, plenty more to get to...all comments are appreciated.
