Atheism, Morality, and Divine Nature Theories vs. Ideal Observer Theories

This another item I found while organizing material on my hard drive. I think I am the author, but I am not certain of that. What is the advantage of divine nature theories over ideal observer theories?  Consider, for example, a divine nature theory of moral value.  On such a view, God’s nature, not God, Atheism, Morality, and Divine Nature Theories vs. Ideal Observer Theories

J.L. Mackie’s Argument from Queerness against Objective Values

In his highly significant book, Ethics: Inventing Right and Wrong, the late Oxford philosopher J.L.

Does Evolution “Explain” Objective Morality? A Reply to Jerry Coyne

Evolutionary biologist Jerry Coyne recently wrote about Leah Libresco’s conversion from atheism to Catholicism based on a moral argument for God’s existence.

Amoral Atheism Part 2

Physics cannot justify why anything is morally right or wrong. No one says that is a defect of physics because that’s not what physics is about. Like physics, atheism is also not about morality. So why should it be a defect of atheism that it cannot justify why anything is morally right or wrong?
