Atheism and Ethics

[Lucian]

I'm a moral realist because there are facts about which actions are most and least harmful.

I am still not because I can’t see an obvious link between harm and some mind-independent non-institutional categorical imperative existing as a property of the universe. I agree it is as plausible a candidate as any if such a standard does exist - but I can’t show it does and most attempts I have seen appeal to intuition and I am just not comfortable with that as a standard by which to make these kind of judgements. 
I guess you could define immorality easily using your standard, and if you defined morality as having to do with harm, then sure morality exists in the sense that harm exists. In that sense you would be a kind of naturalistic moral realist I think, but I still don’t see the standard itself can be shown to exist as something objective. But basing morality on what causes the least harm seems to ignore moral actions that don’t have to do with harm. As an example, going out of your way to do something nice for someone who doesn’t deserve it. Do you have thoughts on that side of it?

As mentioned in previous posts, this is probably my tediously boring standard move from Christianity to doubting other things, but I am not so sure. 

Mentally tired, so sorry if the above was a rant. In the process of moving house and finding it painful! Definitely immoral - I am swung
