The Last Conformist
Irresistibly Attractive
No, this isn't about the Kama Sutra, you gutterminded freak. 
Suppose, for the sake of the argument that I claim
(p) Murder is wrong
and that (p) is true.
Now, consider a hypothetical world were living creatures cannot kill or be killed. Is (p) still true in this world? Presumably, a moral absolutist has to say that, yes, it still is, but I have a hard time seeing how that makes any sense. How is it meaningful to say that it's wrong to do what can't be done?
It seems to me that the truth of (p), if true it be, is contingent on us being creatures capable of killing or being killed. But if we admit that the truth of a moral claim is contingent on the kind of being saying it, we've accepted moral relativism.
I suppose there is a standard answer to this, but I've not heard it. Enlighten me.
