here) when Chunderban Desai exhaustively analyzes Terrestrial history. However:
"'...we don't have the knowledge to say how far [the historical pattern] may apply to nonhumans, if at all,' Desai admitted."
-Poul Anderson, Sir Dominic Flandry: The Last Knight Of Terra (New York, 2012), p. 390.
But he intends to find out. When Flandry questions whether the Merseians are also decadent, Desai asks:
"'...what is decadence to a nonhuman?'" (ibid.)
I think that the Merseian resolve begins to weaken shortly afterwards when the Magnusson Rebellion fails. Tachwyr's rationalization:
"'By adversity, the God tempers the steel of the Race. Let us get on with our quest.'"
-Poul Anderson, Flandry's Legacy (New York, 2012), p. 447 -
- rings hollow.
By contrast with Desai, the Vro-Hi in "Flight to Forever," having advised the First Galactic Empire of many intelligent species on a billion planets, has learned "...the great laws in the rise and fall of cultures..." -Past Times (New York, 1984), p. 262.
If transported to the History of Technic Civilization, the Vro-Hi would be able to assess Terra, Merseia, Ythri etc - unless "...the great laws..." differ between timelines? But I doubt it.
