 One of the challenges of naturalism is that it does seem to many people that there is such a thing as objective good and objective evil, Elie Wiesel in his book, Night. He describes in Auschwitz witnessing a young boy being hanged. Many people, they consider that and they say that is objectively evil. And so what that gives is a challenge for the naturalists. Do I bite the bullet and say, contrary to those moral intuitions, no, there just is no moral evil that's objective. There are things in the Bible that appear to be commanded or commended by God, which appear to be objectively evil. So the only way that we can determine whether it's objectively evil is it becomes not a matter of opinion, but rather criteria. And the strange thing is, when all these people tell me that I have no objective moral standard, the believers don't. Even if it was the deity speaking itself, it would still be a subjective opinion, because they're not giving a reason. It's because God said so. Even as children, we understand because I said so is not an explanation.
