I've no particular view on its desirability, to be honest. It's empirically true within the socio-psychological context, though!
We have very different definitions of "true"
But thanks for humoring my questions; I've run into a fair number of no-objective-truth folks, but only rarely will they follow it through to the extent of accepting that "being human" (or some other descriptor of "behavior they prefer") is not an objectively-binding (or perhaps even objectively-
meaningful) standard, according to their own view.
Incidentally, I agree that scienctific inquiry requires a pre-existing context before it can begin proving or disproving things (within that context). I don't think scientific inquiry is the only means of acquiring information (including the information necessary for those contexts), nor that the underlying truth is purely subjective, but I can understand why it looks that way to you
Though Hearteater brings up a good point about definitions. If the desirability of being-human is "empirically true within the socio-psychological context", is it true whether or not you or anyone else believes it? Would that not make it "objectively" (independent of subject) true?
