Olaf Stapledon, I have found:
"Another Stapledon," which explains why I think that Poul Anderson is a modern Olaf Stapledon;
Cosmic Histories, which lists and describes Stapledon's works, then summarizes the cosmic history of Anderson's "Pride" and Tau Zero;
Stapledon To Stirling, which locates Anderson at a stage intermediate between the classic Stapledon and the contemporary Stirling.
That third item also links to its immediately preceding post which discusses the bases of humanity and morality.
The blog could become endlessly self-referential although not vacuously circular like a cartoon that was circulated at work: woman seated at PC, man standing behind PC, both speaking into mobile phones. Man asks, "Did you receive my email?" Woman asks, "Would that have been the one about your text message?" In that case, the message has got lost among all the media whereas, in the case of the blog, I refer to very substantial works by Anderson, his predecessors and one current successor.
