Straw man. I didn't claim that only statements consistent with a (given) moral theory are moral statements. I only said that a statement that is consistent with one is a moral statement.
But this is false, because, as I pointed out...
You're right. A moral statement is any statement that asserts that something is morally right or wrong. However, any such statement asserted without reference to some moral theory is non-cognitive. The truth or falsity of such statements can only be determined via their consistency or inconsistency with some moral theory.
The second quoted statement doesn't contradict the first, Peter.
Your mistake is assuming that a moral assertion has a truth-value, which begs the question.
That is not an assumption, and it doesn't beg the question. It has a truth value if it follows from premises which have truth values. Which, if the premises are those of a sound moral theory, it does. But see below.
False. The whole point of a moral theory is that it has moral postulates, principles or premises - which are non-factual, and from which other moral assertions can be deduced.
The postulates of a moral theory are factual, although they are not all empirical (though some are). Not all facts are empirical facts.
False. A moral assertion has no truth-value. What's the truth-value of 'capital punishment is morally wrong' or 'eating animals is not morally wrong'? It's precisely your assumption that they do, and that therefore a moral theory must have postulates that are true, that begs the question.
Whether those propositions are true or false depends upon the moral theory against which they're tested.
A factual postulate can't entail a moral assertion, but only a factual assertion has a truth-value. Your 'sound moral theory' is dead in the water.
Methinks you don't understand how theories work. They all proceed from some postulates, axioms, which are taken to be self-evident, which are
assumed to be true without proof. This must be, lest you embark on an infinite regress.
Some of the postulates of a sound moral theory are empirical; they state readily verifiable facts about human nature and the social setting. The axiom codifies the aim, the goal, of the theory.
I take a "morality," a moral system, to be a set of principles and rules governing interactions between agents in a "moral field" (a social setting). I take the aim of those principles and rules to be enabling all agents in that field to maximize their welfare, to the extent that is facilitated or hampered by interactions between agents, as evidenced by the content of most moralities over the centuries. So we choose an axiom codifying that aim: Develop principles and rules governing interactions between moral agents in a social setting, with the aim of enabling all agents to maximize their welfare.
It is possible, of course, to conceive the aim of morality quite differently. Perhaps the most common alternative axiom would be, "Develop principles and rules for conforming human behavior more closely to the will of God." But since that one depends upon unverifiable and unfalsifiable supernatural assumptions it is hardly self-evident.
It is self-evident, on the other hand, that human actions are goal-directed; every action an agent takes aim at some end, some result he anticipates will fulfill some desire, deliver some sort of satisfaction --- that will improve his welfare. It is also self-evident that in a social setting the actions of one agent can enhance or reduce the ability of other agents to improve their own welfare, and hence that some rules of interaction are necessary if all are to be able to do so.
There is nothing mysterious, arcane, or even difficult, in principle, about devising a morality. It is similar to developing a set of traffic rules for a highway system. Their aim is to enable all drivers to get wherever they're going as quickly, conveniently, and safely as possible. It is a pragmatic endeavor. So is morality.
So a moral proposition is true or false depending upon whether it does or does not futher the aim set forth in that axiom (which is usually an empirical question). But if you don't take that as the aim of moral principles and rules then for you the term "moral" will have some entirely different meaning, and would require an entirely different theory.
