How can one determine whether anything has intrinsic or innate value? Would we not, in all cases, be forced to concede that a person could theoretically say that they hold the object in question to have no value at all?
I don't work on this sort of thing, so I won't comment upon the question how one might actually decide whether something has intrinsic value. But I will comment on the overall orientation of the question. It seems to be assumed that, if someone could deny that the object has any value, then that would someone call into question whether it had intrinsic value. But why? People can be wrong about all kinds of things. The fact that something is of intrinsic value does not imply that any particular person will recognize that value. It does not even imply that anyone at all will recognize that value. We might all be completely ignorant of it. So let me ask a question back: What's the significance of the restriction to "intrinsic or innate" value here? Does this worry seem more pressing when those words are included than if they are not? If so, why?
