This paper considers whether theism is compatible with moral error theory. This issue is neglected, perhaps because it is widely assumed that these views are incompatible. I argue that this is mistaken. In so doing, I articulate the best argument for thinking that theism and moral error theory are incompatible. According to it, these views are incompatible because theism entails that God is morally good, and moral error theory entails that God is not. I reject this argument. Since it is (...) the best argument for thinking that theism and moral error theory are incompatible, I conclude that these views are compatible: one can coherently accept both views. (shrink)
