What is 'objective' value?

[Neo-Scholastic]

Unless of course intentionality is already an inherent part of reality.

And what would that mean, for intention to be an inherent part of reality?  Even if God values human life, that's just one more agent's project.  No, this doesn't get around the problem.

Only if you consider God just another kind of particular being among other particular beings, a common assumption by skeptics. In the case of the God of Classical theism, or "The Good", it serves as the objective standard of that which is most to be desired. In Aristotle, this is called Happiness. In Western theology, this is called Blessedness. In other words, the value of human life lies in its potential to strive for and manifest the greatest good of which it is capable in comparison to the greatest possible Good.
