This is the the twenty-fifth post in my Theories of Knowledge and Reality series. Follow the link for more on the series and for links to other entries as they appear. In the last post, I looked at why some people think theism serves as the best non-naturalistic foundation for ethics. This post now looks at an objection to seeing God as the basis of morality.
In Plato's dialogue Euthyphro, he has the character of Socrates raise an objection to the idea that morality has something to do with the gods. If something is good just because the gods view it as good, the gods could command anything, and it would automatically be right. You don't have to be a polytheist for that consequence. How could God's mere choice be the basis of morality? Are good things good because God says they're good, or does God just declare them good based on seeing their goodness? If they are already good, then doesn't that mean God's choice didn't make them good?
