I am going to copy and past my posts from another current thread, just to save time typing.
Morality and evolution are a chicken or the egg paradox. Atheism is a rejection(reconsideration?) of the social authority we construct to enforce our moral code of behavior.
The problem comes when this rejection of the authority is mistaken for a rejection of the code of behavior.
This is where it gets tiresome, because some asshole has to pop up and ask something like, "If there is no God or hell, why don't I kill or rape as many people as I want?"
The simple answer to this simple minded question is, "Apparently, you have." Sometimes people fail to recognise zero is a number. Humans are a lazy species. It maybe our weak behavioral instincts. Turn a wasp loose and it will begin to build a nest. A toad will hop back to the pond where it was spawned, to find a mate. If I wanted to hop back to Panama, I would have to consult a map, or maybe a GPS navigation device, but I'd probably decide to look for a woman someplace close by. A code of behavior makes life easier, and we've never been able resist the easy way.
We have a moral code of behavior because it makes life easier. An easy life gives us more time to do the fun stuff and that is a powerful evolutionary drive. Did our large brain bet bigger because life was easier in ways such as more and better food, lower infant mortality, longer childhood, etc,l or did the large brain make that stuff possible? We're back to the chicken or egg thing, again.
One thing is certain, without the egg, we wouldn't have the chicken.
This sounds reasonable, though I may expound on a few things later, time permitting.
I do want to point out, though: I believe I misinterpreted your "Apparently, you have," answer in the other thread. I took it to mean, "Apparently you
have raped and killed," - but I think what you meant was, "Apparently you
have raped and killed as many people as you want, which is none." IOW: "If you
wanted to rape and kill someone, you
would have."
Have I got it right?
