Imagine there is no "god." Imagine there is no afterlife...no reward for a life of virtue and no punishment for a life of evil. Imagine that you do not believe that humans are somehow "children of god" or intrinsically more "valuable" than animals and plants.
Now given this set of non-beliefs, would you care about thousands of people being killed on the other side of the world - people whom you do not know, and nobody you ever encounter would know? If so, why?
Would you care about the carnage that goes on in our inner cities every weekend?
Would you care about any tragedies that don't affect you or your posse? Why?
If you do care about these things, please explain.
You can abstract from a lot of things, but not from reality as a whole.
There is a Creator and that is purely from REASON. What you do with that is religion or it isn't.
Natural Religion , which is purely religion from reason, gives you 'equality of man" and 'unalienable rights of man"
The question then is not a good one. Whatever you think of what you are not part of, you still have your duties to your family, community, work, citizenship. Who fails at the things you list that doesn't first fail at what I list.
IT takes a perverted 'religion' to posit you being better than other people , in the first place'
Do unto others as you want done is maybe the simplest undeniable first principle of morality and hence of religion at any level.
Don't say the morality thing is religion. Then why does a thief complain when you steal from him? An adulterer when you commit adultery with his wife? A murderer when you murder a dear one of his?
As soon as you make the question of Creator/God an academic question you have been immoral.
When you die and tell God that you just didn't give a sht, you can't complain if HE doesn't give one either.
