[Projoy] My rule of thumb is that when someone questions the possibility of knowing the truth of anything, there is some specific truth they are trying very hard to ignore.

[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.
