[Bm] What view are you moving away from, if I may ask?

[BM] I understand your argument now. A belief is a proposition which must be objectively true or false, whereas a moral value is based on something subjective... I do see where you're coming from, but I'm still not entirely comfortable with it. It seems almost a logical positivist approach to belief - that something can only be a belief if its accuracy can be objectively determined. So what of the question of whether there is a god? Is there a way of determining if there is a god or not? If not, then belief in a god can't be a belief. If you disagree with this, why is it less acceptable for "X is wrong" to be a proposition than "there is a god"? If you agree with it, then is religion in general a set moral values rather than a set of beliefs?

I meant "a set of moral values" rather than "a set moral values" of course.

Ooh, it's getting gritty now...
[Raak] I didn't really have a view to move away from, to be honest. This is partly because I always found ethics by far the dullest area of philosophy and never formally did it. I suppose the view I'm moving away from is the view that there is any sense in which "X is right/wrong" is objectively true or even objectively anything. It may be possible for it to be objectively something, but I'm not sure what, and if it's not truth then I'm not really interested.
[Darren] Oh no, I'm no logical positivist, a position I think is pretty silly (for the uninitiated, this is the view that something can be true only if it can be shown to be true). I don't say that we can't know the truth value of ethical propositions, therefore they can't be true. Rather, I say that they are not propositions at all. They are not stating facts (or falsehoods) of any kind. Thus they differ from the proposition you give of "There is a God," which I certainly think (a) cannot be shown to be either true or false, but (b) is either true or false. That's an unverifiable proposition, but "X is wrong" isn't really a proposition at all, even though it looks like one. Part of the reason I think this is that I cannot imagine how a world in which "X is wrong" is true differs from a world in which "X is wrong" is false other than that one difference. But I think that if a proposition is true it must express something about actual things actually in the world - that is, facts are, as it were, parasitic upon things. So for "There is a God" to be true there would have to be an actual God, whilst for it to be false there would have to be none. But I don't know what kind of "thing" would have to be different for "X is false" to be a fact or a falsehood. Thus it's not merely that we don't know whether it's true or not, I don't think it means anything at all to say that it is true - that is, it's not the sort of thing that can be true. If you follow me.

[Bm] (I assume that your last "X is false" was a misprint for "X is wrong"?) According to the view I am suggesting without necessarily being committed to, what would be different for "X is wrong" to be a fact or a falsehood would be that those with moral insight would agree that X was or was not wrong. That doesn't advance things much, but moves the question to "How does one acquire moral insight?" And also "How can people claiming different moral insights reach agreement on moral facts?"

I just want to correct "those with moral insight would agree" to "those with moral insight would see".

[Raak] Yes, the typesetters did me wrong. I think you're going to have to elaborate somewhat on your suggestion, though. If the sole difference between "X is wrong" being true and false is whether those with moral insight think it is, then that doesn't seem to me to be a very strong claim. Are you basically saying that things are right/wrong because most people (or most appropriate people) think so? But clearly this is quite different from normal propositions - for example, "Jupiter is the largest planet in the solar system" isn't true or false by majority opinion, and neither is "There is a God." Normally we think of propositions being things that people recognise the truth or falsity of, rather than things that they determine the truth or falsity of. Alternatively, if you think that those with moral insight are in fact not determining rightness/wrongness but recognising it, then that begs the question on what grounds these people see that X is right or wrong. Do they just "see" it with Enlightenment-style infallible conscience, with no further explanation? This is quite apart from the problem you suggest yourself, which is how to recognise those with authentic moral insight, and how to deal with the problem of disagreement over morality.
