Sorry. I meant to answer your question, but never got back to it. The less personal and short version of why atheists can act morally is because we still feel certain biological emotions, empathy, shame, guilt, etc. We still act in ways to make our self feel good, just in respect to other people. You can argue that this is still psychological egoism (it's impossible to act in a way that's not self-interested), but a self-interested action is different from a selfish action since a selfish action is at the expense of others.I'd like to ask a question too that I've never really got a satisfactory answer to. Supposing that there is no God, no heaven, hell or afterlife at all. When we die, we cease to exist. What incentive is there for a person who believes that to live a moral life? Because you're making the world better for future generations? Why bother? You'll be dead, what do you care? Because you're making other people more comfortable in their lives? Why do you care, they're not you, so except for the people in your own social circle, there's no reason to help others. Because it's the right thing to do? Who determines what's right? Isn't what's right just whatever you need to do to make your own self as comfortable as you can for the present moment? I have trouble understanding the motivations of atheists to be moral. As for my own self, I would do whatever I could get away with if I thought there were no consequences for my actions, and I sure wouldn't expend any effort to help anyone other than my own friends and family, and even then only when it would somehow benefit me, directly or indirectly.
That's my answer, but I feel most religious people don't buy this, but remember that this point can also be flipped around on religion, "You are only acting good out of selfishness to get into heaven." Anyway, I think no matter what you are, you can agree there is more to human morality than just hedonism (Unless of course you're a hedonist of course lol).
