here. However, I also think that Anderson presented more information on Tahirian planetary engineering so I hope to write a more detailed summary when I have reread Starfarers to that point.
It has been suggested here that Anderson's early story, "Genius," was a false start, disagreeing with the author's later expressed moral views. "Genius" is a paradox: on the one hand fairly crude early hard sf, with Magellanic barbarians threatening a Galactic Empire; on the other hand, serious discussion of the factors that facilitate social stability and/or progress. I will have to reread "Genius" to assess the judgment that it is a false start.
Then, after rereading some more of Poul Anderson, I will have to read for the first time some more works by SM Stirling.
