Yeah, the sticky point I've always found in the man is just a higher evolved animal position is the arbitrariness of cooperation. That is to say, any expectation one human has of another seems arbitrary to me without a base set of rules set forth by a higher authority.

The writings of C.S. Lewis crystallized a lot of this in my mind.

I'm really disturbed by that mindset. Surely, you are not saying that without belief in some sort of God, you personally would cease cooperation and rape and murder and steal?

I'm an atheist, but I certainly have no desire or intention or plan to cease cooperation. Just the opposite, I think it's extremely important, and it is also extremely important that we cherish and enforce and cultivate it.

As just a little example, for me some sort of communal health insurance covering everyone is a matter of course, as for most citizens of developed nations. (I'm aghast at the fact that many people oppose it in the USA, and I note in passing that it appears to be mostly religious people.)

Next, I have the same expectation of basically everyone I encounter (except some sociopaths, against one has to guard appropriately).

Finally, I think there are many good reasons for it, and the position that man is ("just") a higher evolved animal is not at all incompatible with it.

No I'm not saying a belief in God is necessary for what we would agree upon as moral behavior. However, I could easily see the case being made by individuals who might think that what we agree on as morally correct behavior being nothing more than our arbitrary beliefs. And that, from their perspective, rape or pedophilia makes them feel good in the way eating red meat makes them feel good.

So on a spectrum with complete moral bliss on the far left and complete degeneracy on the far right, I think we live somewhere on the left side. Furthermore I think a big reason we live there and not right of center is the wide spread belief in a higher authority/authorities.

Why? From where is your sense of "Fair Play" derived? Does it all boil down to the non-aggression principle and if so, from where is that derived?

> what we agree on as morally correct behavior being nothing more than our arbitrary beliefs

Interesting. I am also concerned by moral arbitrariness and relativism, but fear it comes from somewhere else:

I fear that religion opens up the door to moral relativism, because you can go and say "don't eat shrimp" (Leviticus 11:10), or "don't eat pork", or "don't eat cows", or what have you, claiming "it says so right here, in this holy book full of true revelations".

That's a trivial example, but the same applies for more serious issues: morality based on (religious) revelation is hard to verify and discuss, and somewhat arbitrary.

But if we empirically agree on one real world, empiricism and evidence, we have at least a common basis and need very few, very basic moral principles (it really boils down to the golden rule, or somewhat more sophisticated versions of that, like the "veil of ignorance" in John Rawl's Theory of Justice.)

So, in purely practical terms, I think this notion of some psychopath running around claiming "there's no God, thus I can do what I want" is a non-issue.

If you furthermore seek a philosophical "Letztbegründung" (i.e. ultimate reason, where "the buck stops"), there are attempts e.g. in discourse ethics ("if we are talking, we are already implicitly subscribing to certain axioms, otherwise we would not need to talk"). But I don't think it'a a big problem.

The problem lies less in the foundation and more in certain topics, I think (think of abortion, contraception, war).

You can explain a lot without a higher authority. For instance humans gossip so if you screw someone over, word spreads and can have adverse consequences. That can help do gooders and help pro do good genes to spread in the gene pool for example.

Interesting article. Note that it only talks about improving cooperation "within" the circle, i.e. among "co-religionists", as the article puts it.

I think you'd find increased cooperation within many other types of groups. What we should aim for, of course, is to expand this circle of concern ever further, beyond religion.

So, just want to clarify that this might have been an benefit of religion in earlier days, but is by no means an argument for them today.
