Is Moral Nihilism a Morality?

[vulcanlogician]

Ironically, we don't disagree on the things that make moral nihilism in some sense unintelligible.  I'm only adding another to the list.  The embeddeding problem.  

You'll probably get a huge kick out of this, courtesy of S. Blackburn(1984) 

(a) H!(B!p --> B!q)

H! is the hooray operator.  B! for boo.  The relationship between p and q demonstrates attitudes or beliefs.  

Noncognitivist nihilism posits that moral operators aren't actually talking about what they're about, as opposed to cognitivist nihilism which asserts that they are - but get it wrong.  Above we can see that expressivism as a noncognitivist theory could, at least in principle, be a logical product - and thus we're back to wondering whether there is any valid distinction between logical and moral normatives.....even in a noncognitivist framework.

I did get a kick out of it. I had to refer to truth tables (my symbolic logic is a lil' rusty) and I still had a rather difficult time working through it. I actually didn't quite work through it. It's pretty complicated. But fascinating nonetheless.
