IL My understanding was that Terminal Values are not something you ever observe directly (nobody can simply list their Terminal Values). Moral arguments change what use as our approximation to the Moral Calculation. However, if moral arguments did make our actual moral calculations diverge (that is, if our actual moral calculation is not a state function with respect to moral arguments) then that does disprove Eliezer's meta-ethics (along with any hope for a useful notion of morality it seems to me).
