You can't seem to grasp that an "ought" statement can be objective whether or not the goal is objective. It can be, because the "ought" statement references the goal; it is a conditional --- "If you wish to do X, you must (or should) do Y." Propositions of that form can be true and objective.
Let's be precise: a goal Y is never objective, so that isn't the issue. And wanting goal Y is always subjective. The claim that action X leads to goal Y may be true and objective. But that doesn't establish the objectivity of a moral assertion, such as 'slavery is wrong' . . ."
"Slavery is wrong," as a stand-alone proposition, may be subjective, because it means no more than, "I don't approve of slavery." If the utterer intends it to mean anything more than that, if he believes it has some "objective" truth value --- a truth value independent of his personal opinion --- then he will be assuming some criterion of "rightness" and "wrongness."
When people pronounce some act morally wrong they usually believe they are saying something more defensible, and more objective, than merely uttering a personal preference. They have some underlying moral principle --- some moral axiom --- in mind. If you ask someone who declares, "Slavery is wrong," WHY it is wrong, he'll try to give some answer:
"It is against God's will."
"It is illegal."
"It conflicts with the principle that all men are created equal."
"It causes suffering, and one should not make others suffer."
Etc. What he is not likely to answer is, "Because I don't like it."
People believe their moral judgments are grounded in some larger truth. When that is the case, then the proposition is actually a conditional, "If X is the case, or if you believe X, then slavery is wrong."
Just like "should" and "ought," moral rightness and wrongness are
instrumental. To call any action "wrong" is to say it conflicts with, is inconsistent with, some standard, some rule accepted as valid or sound, or with the attainment of some adopted goal. Enslaving someone is wrong for the same reason that driving on the left side of the road (in the US) is wrong, or connecting the black wire to the neutral bus in an electrical panel is wrong --- they are all acts which conflict with some accepted standard, are inconsistent with some accepted principle, or will not advance one toward some chosen goal. Whether they are or are not compatible or consistent with that standard or goal is usually objective.
Upshot: if you declare some act to be morally wrong, and you mean something more substantive than that you don't like it, then you will have some broader goal or principle in mind, and you are declaring the act in question to be inconsistent with it. Whether the act in question is or is not consistent with that goal or principle is usually objective. Whether the larger principle is sound, or the goal worth pursuing, is a separate question. The reasons for adopting any principle or goal are always pragmatic, including the moral "Fundamental Principle" I gave earlier.
"Objective" doesn't mean, "Agreed to by everyone," or, "true of 'external reality'," or, "From God's point of view," or anything with any metaphysical/ontological implications.
I agree that consensus and divine perspective have nothing to do with objectivity. But what does your definition of an objective assertion - 'with public truth conditions' - mean, if it isn't something to do with 'external reality'? (I may have misunderstood your point here.)
It means that the state of affairs asserted in the proposition can be confirmed or disconfirmed by any suitably situated observer. "It is raining outside" is objective. That means that anyone in that area can confirm it by looking out the window or stepping outside. That criterion, BTW, makes no assumptions about any "external reality." The speaker and observers may all be solipsists, but they'll still be able to confirm or disconfirm that proposition. If they experience the percepts the proposition predicts, it is objective, even if they all consider it (and each other) parts of a hallucination.
The real issue here is, "What is the aim, goal, of moral theories, moral codes, moral rules?" If you profess to interested in "morality" you have to answer that question somehow.
No, that's not the issue here at all. We're discussing what could make morality objective. That moral theories, codes and rules have one aim or goal is a matter of opinion - as is the claim that we should have such an aim or goal at all, let alone a particular aim or goal. And none of these confers objectivity on moral aims, goals, codes or rules.
As I said above, if you make any sort of declaration that doing X is wrong, you will
probably have some goal or broader principle in mind, and you will
probably be claiming that X is incompatible with that goal or principle. Whether it is or not is (usually) objective. If you don't, then you will merely be declaring that you don't like X --- a fact that will interest no one, and certainly not persuade anyone to change their own opinion of X. If we want moral discussions, arguments, to be meaningful and persuasive we need to set forth, and justify, those proffered goals or principles.
I am interested in morality, which is why I'm concerned to demolish the delusion and expose the lie that morality - more precisely moral assertions - are or can be objective. That lie has encouraged and justified a great deal of human wickedness.
It is not the claim that a moral judgment or rule is objective that results in the wickedness. It is the fact that the underlying goal of that rule or judgment is wicked.
