The Right of a Superior Species: Averted by responsible Superior Species, who understand why it’s not a good idea to go around granting yourself an Omniscient Morality License. (Even if the traditional tactless way to put it is along the lines of “The corollary of being a Superior Species is the responsibility to behave in a manner befitting a [morally] Superior Species.”)
Trope-a-Day: Superior Species
Superior Species: We pretty much covered this territory under Can’t Argue With Elves too, didn’t we?
Well, to expand in general, rather than pick a specific example, especially since they started building their own future generations with transsophont technology, there are very few successful species that don’t maintain their general superiority at some level, at least to themselves, except those who are part of polyspecific civilizations and maintain their species-group’s superiority, instead. Of course, since they’re all using culturally-defined measuring rods of different lengths and configurations, many of them – the non-deluded ones – are right in their own terms, even if no-one else would agree to them generalizing their standard across everyone else. Which more or less explains the problem with the whole notion of generalized “superiority”, now doesn’t it?
