Dear Mr. EvD,
As promised, since you did not answer, or even address, the point I asked of you, I cannot bring myself to continue the discussion any longer.
You make statements about history (such as that the medieval Christians thought the world flat — Dante included?) that betray an ignorance of the subject matter.
I asked you for specifics, to name the Papal Bull showing the hostility of the Church to the progress in the Dark Ages, and listed the inventions: you declined to answer.
I asked you if you were familiar with the writings of the founders of science, whom I listed by name, all medieval Christians. You declined to answer.
