John Ridenour conducts a curious interview. First, his interviewee and he are of different species. Secondly, neither is a native of Freehold, the planet where the interview is conducted. The blond-haired, hatchet-faced interviewer is from Earth, here known by its Latin name, Terra, whereas the blue-feathered, sharp-snouted interviewee is from Aruli, which he calls "Eternal Aruli." -Poul Anderson, Captain Flandry: Defender Of The Terran Empire (New York, 2010), p. 12. Thirdly, neither speaks the other's language. However, both are fluent in the principle language of another space-traveling race, the Merseians, although the Arulian has difficulty with some Eriau phonemes.
To summarize, a Terrestrial interviews an Arulian in Eriau on Freehold. Thus, the Earthman interacts in different ways with three other planets. Might such colorful cultural combinations occur in our future? Yes, if, like Ridenour, we inhabit "...a universe that produces sophonts as casually as it produces snowflakes." (p. 7) But I doubt that. If it were true, then the extinction of a rational species, although tragic, would not be as great a tragedy as if that species were the only intelligent race in existence.
