"'In my race, messages are always intended as vectors on the world line of the percipient.'" (Starship, p. 229)
I don't understand that. Do you?
Do the Reardonites, Smokesmith's race, directly perceive world lines? It sounds as if he treats them as more than a theory or a mathematical abstraction.
Trevelyan and Smokesmith discover a supernova. Thus, Poul Anderson's "The Pirate" becomes a supernova story like:
"The Star" by Arthur C Clarke;
"Day of Burning" by Poul Anderson;
"Lodestar" by Poul Anderson.
In "The Pirate" and "The Star," a rational species has been destroyed. In "Day of Burning," such a species is saved. In "Lodestar," the explosion occurred long ago but had scientifically interesting, and industrially exploitable, consequences.
Trevelyan says that civilization is based on communication. Yes. He adds that life:
"'...depends on communication and feedback loops between organism and environment, and between parts of the same organism.'"
-Poul Anderson, The Peregrine (New York, 1979), Chapter IV, p. 28.
"...communication and feedback loops..." is redundant - unless "communication" implies conscious communication, in which case it is wrong.
Trevelyan argues that there are natural limits to the size of information-processing brains and computers and that the number of extrasolar planets contacted is growing beyond anyone's ability to coordinate them. Anderson's fiction primarily celebrates those who value and exercise freedom. His Psychotechnic History mainly focuses on successive guardians of social order. Trevelyan of the Coordination Service is about to come into contact/conflict with the Nomads. Asked why the Cordys dislike the Nomads, he replies:
"'They're the worst disruptive factor our civilization has...They go go everywhere and do anything, with no thought of the consequences. To Earth, the Nomads are romantic wanderers; to me, they're a pain.'" (p. 30)
Anderson always presents both (or all) sides of any argument.
