I am uncomfortable with the notion that there is an absolute measure of whether (or to what degree) a particular entity is morally significant. It seems to touch on Eliezer's discarded idea of Absolute Morality. Is it an intrinsic property of reality whether a given entity has moral significance? If so, what other moral questions can be resolved Absolutely?

Isn't it possible, or even likely, that there is no Absolute measure of moral significance? If we accept that other moral questions do not have Absolute answers, why should this question be different?
