So the question is how do we justify moral beliefs?
I subscribe to multiple forms of justification, I don't believe we have to just pick one. Some moral truths are self-evident in certain circumstances. Others are justified by their coherence with other beliefs - we form a web of support. And finally I think we can have intuitional justification. So I'll opt for a full house of justification theories!
There are a number of problems with moral scepticism:
- It is an intellectual dead-end
- It doesn't correspond with common-sense
- It is an immoral position to hold IMO
