“The “scientific method” didn’t bring “man out of the Dark Ages.”
Charlemagne did.”
Gee, I thought the Crusades started the process!
Without digressing on Petrarch's metaphor in philology and rhetoric on "dark ages" and related controversies, it's plausible only as the short period after the fall of the Roman Empire.
The development of scientific method is a very long, drawn-out process from Roger Bacon's experiments through the 17th century. The additional problem is that the triumph of scientism and moral relativism in the present day coincides with the Islamicization of Europe and the reappearance of nose rings and butt tattoos on women.
