Atheism and morality

[Inigo]

you don't seem to have grasped my argument at all. Of course we can and do have concepts of things that do not exist.
We have a concept of morality. My point is that there would only be something answering to that concept if a god and an afterlife exists.

Your point fails. I don't really even see how you are getting there.

How do you know it fails then? You don't know how I got there, but you're sure my route was fallacious? How very odd. I wish I had the ability to know in advance that someone's point was false prior to even knowing what it was.
