1 If the assertion ‘a moral theory is objective’ is false, then the assertion ‘a sound moral theory is objective’ is also false. It’s the assertions made in setting out the theory that can be objective or subjective – and can have truth-value. You acknowledge that in your second paragraph. And it’s not just somewhat inaccurate to call a theory objective or subjective. It’s false.
True; theories
per se are neither objective nor subjective. Neither are they true or false. But to say, "Theory T is neither objective nor true," would often be misleading. E.g., "Quantum theory is neither true nor objective," would likely be interpreted to mean it is bad theory. Which it isn't.
If QM yields propositions which are empirically verifiable, and consistently generates predictions which observation confirms, then it is much less misleading to say it is a true, objective theory, though that is somewhat inaccurate ---only somewhat, because it generates propositions which
are true and objective. But it would be better just to say it's a good theory.
2 Soundness normally refers to an inference whose premises are or are taken to be true. So it’s unclear how a theory (which contains but is not an inference) can be sound. Perhaps you just mean 'acceptab'e' or 'plausible'.
A sound
argument is one whose premises are true and whose conclusion logically follows from them. A sound
theory is one whose axioms are true (or taken to be true) and whose theorems follow from them and generate confirmable predictions.
3 You say a theory is sound if its axioms are true. But a moral goal assertion – ‘our goal is Y’ has only trivial truth-value: it would not be true is our goal were not Y. And, if Y is a term, such as ‘human well-being’, it has no truth-value, and to call it objective or subjective is false, because only assertions can be either of those.
Not trivial at all. "Fundamental Principle" (Axiom): "The aim, or goal, of moral philosophy is to devise or discover principles and rules governing interactions between agents in a moral field which will allow the welfare of all agents to be maximized."
That axiom is
accepted as true. Some definitions and postulates follow the axiom, and theorems asserting principles and rules follow from them. Whether those principles and rules are consistent or conflict with the axiom is objective.
And of course you're right that if "Y is a term, it has no truth value." But the goal of a moral theory is not a term; it is a proposition.
Besides, as you say, an axiom has to be ‘accepted as true without proof’, so truth-value is irrelevant anyway.
What? If it is accepted as true, then it clearly has a truth value, and it is not irrrelevant.
4 It follows that, since the axiom of a moral theory can’t be objective, the objectivity of its theorums is irrelevant.
Irrelevant to what, or whom? Certainly not to those who share that goal, or to the attainment of that goal. "Relevance" always relates to something. If the theorems relate to the stated goal, then they are not "relevantly irrelevant." That they may be irrelevant to some other goal or interest is itself irrelevant.
Coherence, consistency and conformity to supposed (and always disputed) facts about human nature and society don’t in themselves confer objectivity on the theory.
I think we've already covered the "objectivity of the theory" issue. What lends objectivity to the theory is the objectivity of its theorems (though the theory
per se is not objective, strictly speaking). And I'm not sure what "always disputed facts about human nature" you have in mind.
But an ‘advisory’ assertion isn’t a rule – or rather, it’s somewhat inaccurate to say it is.
A statement asserting some regularity or advising some generally applicable strategy or methodology is well within the common meaning of "rule" ("As a rule, you should tell the truth").
As it happens, I think your assertion that ‘a goal not pursued is not a goal at all’ is false, and easily falsifiable.
I'd be happy to debate that, but it is tangential.
But even if it were true, the assertion ‘if your goal is Y, you ought to do X’ doesn’t mean ‘if your goal is Y, it is morally right to do X’. And that assertion – like all genuinely moral assertions - has no public truth conditions, so it isn’t objective. It’s a matter of moral judgement, belief or opinion.
It certainly does, if "Y" is a moral goal. And whether X advances or thwarts that goal is objective; it has public truth conditions. An action that supports a goal is the
right action, one that thwarts the goal is a
wrong action, by definition, relative to that goal (this is the instrumental sense of "right/wrong"). If the goal is a moral one then those instrumental rights and wrongs become moral rights and wrongs.
Whether an act is morally right or wrong is, to be sure, a matter of judgment, belief, opinion. But judgments, beliefs,and opinions are themselves right or wrong (factually correct/incorrect). An act is morally wrong if it conflicts with an adopted moral goal, which is objective. If someone who shares that goal judges it to be right his judgment is (factually) wrong.
What remains is your definition that an assertion about morality is a moral assertion. From that definition, you deduce that 'action X leads to goal Y' and 'if your goal is Y, you ought to do X', because they're 'about' morality (moral goal Y), are objective moral assertions.
But this is a definitional sleight-of-hand. (Perhaps 'sophistry' is unfair, for which I apologise. I'm sure you have no intention to deceive.) If an objective assertion refers to a moral assertion, which is not objective (because it expresses a moral value-judgement), that doesn't mean the moral assertion magically becomes objective.
Well, you're indulging in some sleight-of-hand of your own there. The theorems of a moral theory don't merely "refer to a moral assertion." They assert that various acts advance or thwart a given goal. Whether they do or not is objective. If that goal is a moral one (which the one in question is, also by definition), then those theorems are moral theorems; they assert moral principles and rules, just as a speed limit on a certain stretch of roadway, aimed at the goal of improving traffic effciency and safety, is a traffic rule.
Sound moral judgments are not subjective opinions expressing personal values.They express matters of fact.
