Still Not Getting It.
[On evil not existing on naturalism:]
Actually, it does. Just like it does for you. Evil is simply a word you use to describe an action or outcome, such as large amounts of suffering. Just like a theist, we can recognize this suffering and label it.
[On morality as an evolutionary bi-product:]
I don’t understand why theists are so scared of this prospect – the idea that we are responsible for our own behavior and as a society or civilization or species, we decide what is ethical and unethical. If you looked around, you’d see this is already the case, since each country varies somewhat or in some cases, wildly in what they deem lawful.
Religious people subjectively pick and choose what they find to be evil or not in their respective holy books. One Christian might point to Leviticus and say gays are abominations, while another points out that Jesus said to Love your neighbor.
It’s okay, you can think for yourself. I know it seems easier to wish it was all written down in a book, but even that book is written by other human beings who are also writing what they found to be distasteful. They just happened to tell you that their societal or personal rules were backed by an almighty God and you bought it.
On the one hand soda fizzes, on the other, innocent people are killed. You might call the latter “evil”, but on naturalism, there is no ontological difference between the two, they are two ontologically indistinct events that merely have, as you say, different labels.
You might personally find one of those confluence of atoms distasteful. Someone else might not. If naturalism were true, the both of you might as well be arguing about which between chocolate or vanilla is tastier. Because, in the end, it’s merely your opinion that one particular atomical arrangement is better than the other. So the difference between you and someone else who prefers the other arrangement of atoms reduces to merely one of taste. Making every single one of your moral claims extend no farther than yourself.
Which invariably means that you objectively have no business telling others what they should or should not do. Or you could, if you want to, but with the qualification that anyone else’s opinion on the matter is as valid as yours.
And this is why it’s a bit amusing you think your “we decide what’s ethical and unethical” bit is an adequate and clever response. Since with this, you merely rebut your own argument in a manner you did not anticipate: Because if that is the case, then what the hell are you complaining about?
All those immoral things Christians do of which you speak are merely what they’ve decided was ethical. Why is their ethical decisions any less valid than yours when you admit all moral claims are merely what we “pick and choose” and “what we decide”? And if it’s just a matter of us “deciding what’s ethical and unethical”, then morality is simply a case of might makes right, in which case who are we to say someone like Chairman Mao, say, was doing it wrong? After all, he has simply “decided what’s ethical and unethical”.
