Atheists who announce "I'm good without god"

[polymath257]

 Hmm....I haven't been attempting to do so. What specific question do you think I am avoiding? I have given the reasons why we have the moral feelings we have. I have expressed why those moral feelings lead to a man beating his wife to be wrong. I have described why such moral feelings in no way imply the existence of a deity. And I have pointed out that this all is consistent with materialism.
What else are you wanting me to address?

1.)   How you came to the conclusion that morals are the result of evolution?
2.)   Do you think that there is really something wrong with a man beating his wife, or is it just a social convention, that could have evolved otherwise? 

And I'll  some more (related)
3.)    Can something be morally wrong, in spite of social convention or popular endorsement?   Can one society or individual be judged as being more moral than another?

1. Because other animals have the basics of a feeling of fairness and of compassion. They also tend to be social species. And, the basics of sociality require the types of rules that *are* morality.

2. It could have evolved otherwise, but then we would be a very different species. To be *human*, with our social sensibilities and our evolutionary history, implies we respond negatively to this type of behavior.

3. Yes, one society can be regarded as being less moral than another. it all depends on what encourages human happiness and well-being. Same for individuals.

You are just pushing the issue back to causing harm, and saying causing harm is wrong.   The question is if it is really wrong, or just a matter of individual opinion or social convention.  This doesn't get you out of the problem of objective morality.   And if you say that it is subjective, then you can't really criticize others for being immoral, other than just expressing your feelings (or whatever).

Think of it as a matter of *species* convention. Morality isn't objective in the sense that it is determined by something outside of humans. But it is also something that is part of being human.
