Suppose X is a moral nonrealist (but not a nihilist: he does have moral values, he just doesn’t think they’re built into the structure of the universe somehow), and he’s doing something that actually isn’t compatible with his moral values but he hasn’t noticed. Crudely simple toy example for clarity: he’s torturing kittens because he’s a utilitarian and enjoys torturing kittens, but he somehow hasn’t considered the kittens’ suffering at all in his moral reckoning. Y (who, let’s suppose, is also a moral nonrealist, though it doesn’t particularly matter) points out that the kittens are suffering terribly. X thinks about it for a while and agrees that indeed his values say he shouldn’t torture kittens, and reluctantly stops doing it.
Yes, the subjective argument works in the special case where someone ’s behaviour doesn’t jibe with their actions, and, no it still doesn’t have the potential work as well as objective arguments in any other case.
This seems to me a perfectly satisfactory way for things to go, and in particular it is no less satisfactory than if X is a moral realist who believes that hedonistic utilitarianism is an objective truth and stops torturing kittens because Y convinces him that the objective truth of hedonistic utilitarianism implies the objective truth that one shouldn’t torture kittens, rather than “merely” that his own acceptance of hedonistic utilitarianism implies that he shouldn’t torture kittens.
“Oh, but instead of being convinced X could just say: meh, maybe you’re right but who cares? And then Y will have no good arguments.” Sure. But that’s an argument not against moral nonrealism but against moral nihilism: against not actually having any moral values of any sort at all.
It’s not perfect because it only works in edge cases. Objective morality is better even if it still isn’t perfect, because objective facts and principles have normative.force...they are not just Bob stating his personal preferences to Alice who is entitled to stick to her own.
Realistic arguments get their normative from rational norms. People are more likely to agree on rational norms than object level ethics.
“Oh, sure, X may be convinced, but that doesn’t count because it wasn’t a realist argument. Only realist arguments count.”
I don’t say that. I said they more likely to work.
Well, then your argument is perfectly circular: nonrealism is bad because nonrealists can’t make realist arguments. And, sure, I will gladly concede that if you take it as axiomatic that nonrealism is bad then you can conclude that nonrealism is bad, but so what?
No, my real objection is not that there are no good realist arguments.
That’s doesn’t address the previous point, the hypothetical that if there were such a thing as a realist argument, it would be better. If you want to say there or not actually any satisfactory realist arguments, you don’t need to fight the hypothetical.
I’m not sure quite what you mean by that phrase, though. If you mean arguments that start from only nonmoral premises and deduce moral truths then as it happens I don’t believe there are any; if there are then indeed moral realism is correct; but, also, if there are then they should have as much force for an intelligent and openminded nonrealist (who will, on understanding the arguments, stop being a nonrealist) as for a realist.
There are of course multiple types of realist argument that work in different ways.
And to say that you have disproved all of them is a pretty claim since it implies you know what they all are.
ou say “any realist argument” but it seems to me that that’s obviously wrong for the reason I’ve already given above: “you shouldn’t torture kittens because hedonistic utilitarianism is objectively right and torturing kittens produces net excess suffering” is a realist argument, but it is exactly paralleled by “you shouldn’t torture kittens because you are a hedonistic utilitarian, and torturing kittens produces net excess suffering” which is a perfectly respectable argument to make to a nonrealist hedonistic utilitarian.
It’s not clear that utilitarianism isn’t realism.
Of course I agree that I can’t be completely sure that there are no good realist arguments (whatever exactly you mean by that), or indeed of anything else. If a genuinely strong argument for moral realism comes along, I hope I’ll see its merits and be convinced. I’m not sure what I’ve said to make you think otherwise.
It seems to me that your last paragraph amounts to a wholehearted embrace of moral nonrealism. If moral realism versus nonrealism is something we are constructing, something we could choose to be one way or the other according to what gives the better outcomes—why, then, in fact moral realism is false. (Because if it is true, then we don’t have the freedom to choose to believe something else in pursuit of better outcomes, at least not if we first and foremost want our beliefs to be true rather than false.)
If we can construct something like MR, then MR cannot be dismissed entirely.
Since subjectivsm, emotivism, and nihilism have various problems that moral.p realism would not have , so long as it can be made to work. If MR does not exist, it would be necessary to.invent it
Minimally Moral realism is the idea that moral claims have truth values. Maximally, it is the idea that it requires it’s own domain of non natural entities … A an idea driven by the correspondence theory of truth, and the is-ought gap. The
The apparent requirement for supernatural entities is a common reason to reject MR, but many naturalist theories of realism are available. Eg evolutionary ethics, contractarianism, Kantian ethics and game theoretical ethics. Maybe utilitarianism as well.
.
Naturalistic ethics can still be objected to on grounds of the is-ought gap. --.but I will argue that there is no such thing.
How a thing should done is well. It is possible to gather bodies of theoretical and practical information on how to do something—build a bridge, or play chess—well. Such methodological knowledge is conditional: if you want to achieve X, you should do Y. So if we want to apply it to ethics, we need to figure out what ethics is for, what it’s purpose is.
This we can do. Ethics is social. If you are all alone in a desert island , there is nobody to steal from or kill. Ethics fulfils a role in society, and originated as a mutually beneficial way of regulating individual actions to minimise conflict, conserve resources, and solve coordination problems.
This implies there is no universally correct system of ethics, since different societies operate under different constraints.
This does not imply that any defacto moral system is ideal. Therefore, it is possible to judge how well adapted a particular ethical system is. Therefore , a pragmatic twist on moral realism is available, and a problem of typical relativism, that “anything goes” so long as it’s done by a group—is avoided.
(Your blockquotes have the wrong number of levels of quoting in various places, which is kinda confusing. My apologies if anything below is nonsense because I’ve got mixed up about whether you’re quoting me or stating your own opinions.)
Objective morality is better even if it still isn’t perfect, because objective facts and principles have normative force
I agree that if in fact moral realism is correct then arguments based on the actually-correct moral facts have normative force. That would no doubt be very nice, if in fact we knew that realism is correct and knew what the actually-correct moral facts are. But if we all knew those things there’d be no need for the arguments in the first place.
I agree that if everyone concerned is a moral realist then this may make them more willing to be influenced by moral arguments. But I say “may” rather than “will” deliberately. Actual moral realists are almost always some specific kind of moral realist, after all. A utilitarian moral realist will not be particularly moved by a divine-command-theory moral realist’s argument “you shouldn’t torture kittens because God says not to”.
In practice, as I’ve said upthread, what actually happens is that people are somewhat susceptible to moral arguments based on premises they share—which can happen whether or not they’re moral realists—and that’s what matters rather than whether either party involved believes that the premises in question are part of the fabric of the universe.
There are of course multiple types of realist argument that work in different ways.
And to say that you have disproved all of them is a pretty claim since it implies you know what they all are.
It would indeed be a pretty big claim, but it isn’t a claim I ever made and I’m not sure what makes you think I did. What I said is that “as it happens I don’t believe that there are any” (sc. arguments that start from only nonmoral premises and deduce moral truths); that’s not at all the same thing as claiming to have seen and refuted all possible arguments of that type, which of course I haven’t done any more than you have seen and refuted all possible arguments against moral realism.
It’s not clear that utilitarianism isn’t realism.
As I’m using the terms here: utilitarianism is an ethical position (“such-and-such things are morally good, such-and-such other things are morally bad”) and realism is a metaethical position (“moral goodness and badness are objective realities”). You can be a utilitarian but not a realist, if your own moral judgements are utilitarian ones but you don’t think that when you make them you are making objectively true statements about objective reality. (Just as when you say that X is delicious, Y is boring, Z is sexy, etc., you really mean those things but probably don’t claim that they are objective facts.)
If we can construct something like MR, then MR cannot be dismissed entirely.
I don’t really know what that means. In any case, I don’t dismiss moral realism, I just think it’s probably wrong. But, as I said before and you don’t seem to have offered any counterexamples to: if you’re constructing some moral theory then I think by definition it’s not actually a realist theory.
its own domain of non-natural entities [...] many naturalist theories of realism are available.
I have the impression that you think I am arguing “moral realism implies that naturalism is false, and therefore moral realism is wrong”. I am not making that argument. For that matter, I am not making any argument that moral realism is wrong in this thread. (I happen to think it is, but nothing I am saying depends on the wrongness of moral realism.)
This implies that there is no universally correct system of ethics
So you are, in fact, not a moral realist. Given which, I don’t understand why you have been arguing so insistently that moral realism is better.
Therefore, a pragmatic twist on moral realism is available
Your pragmatic twist on moral realism is not in any useful sense (so it seems to me, at least) a form of moral realism. Which is (as far as I’m concerned) absolutely fine, and something along the lines of “human flourishing, in such-and-such a sense, will be best achieved if we all adopt such-and-such an ethical system” may well be true. It’s just not moral realism.
(And if it has any particular advantage when it comes to persuading people to change their behaviour, I don’t see why.)
I agree that if in fact moral realism is correct then arguments based on the actually-correct moral facts have normative force
I am not talking about some particular set of object level moral facts. I am taking it that logical (etc) claims have normative force anyway, and MR being based on that, so that MR leverages existing rational norms.
I agree that if everyone concerned is a moral realist then this may make them more willing to be influenced by moral arguments
But I am saying that people only need to be rational to be swayed by arguments from, eg. consistency.
Actual moral realists are almost always some specific kind of moral realist, after all. A utilitarian moral realist will not be particularly moved by a divine-command-theory moral realist’s argument “you shouldn’t torture kittens because God says not to”.
Arguments that actually work are the kind that are based on widely accepted principles.
As I’m using the terms here: utilitarianism is an ethical position (“such-and-such things are morally good, such-and-such other things are morally bad”) and realism is a metaethical position (“moral goodness and badness are objective realities”). You can be a utilitarian but not a realist, if your own moral judgements are utilitarian ones but you don’t think that when you make them you are making objectively true statements about objective reality. (Just as when you say that X is delicious, Y is boring, Z is sexy, etc., you really mean those things but probably don’t claim that they are objective facts.)
You can be a utilitarian and a realist, as well. You can regard facts about pleasure and suffering to be both objective facts and (intrinsically , stance independently) normative fact. (Sam Harris’s ethical theory works that way).
I don’t really know what that means. In any case, I don’t dismiss moral realism, I just think it’s probably wrong.
There’s very little difference in that distinction.
if you’re constructing some moral theory then I think by definition it’s not actually a realist theory.
There can be truths about human constructs, e.g. Engineering, Economics.
I have the impression that you think I am arguing “moral realism implies that naturalism is false, and therefore moral realism is wrong”. I am not making that argument. For that matter, I am not making any argument that moral realism is wrong in this thread
I noticed. In the absence of your arguments, I have addressed some of the standard arguments against MR.
This implies that there is no universally correct system of ethics
So you are, in fact, not a moral realist.
Lack of universalism does not imply lack of realism. MR requires moral claims to have mind independent truth values …but their truth values can be dependent on nonmental things. Objective truths can be local, indexed to time, and space.
Your pragmatic twist on moral realism is not in any useful sense (so it seems to me, at least) a form of moral realism. Which is (as far as I’m concerned) absolutely fine, and something along the lines of “human flourishing, in such-and-such a sense, will be best achieved if we all adopt such-and-such an ethical system” may well be true. It’s just not moral realism.
It not nihilism, or anything-goes subjectivism either. The point is to recover as much realism as possible.
You don’t need to be a moral realist to be swayed by arguments from logical consistency. If I say “I regard animals as moral patients and therefore won’t eat them, but I do eat fish and chicken” then pointing out my inconsistency has much the same force whether I’m a moral realist who thinks “animals have moral importance” is a fact about the universe or a moral nonrealist for whom it’s a fact about my values.
Arguments that actually work are the kind that are based on widely accepted principles.
What matters isn’t whether a principle is widely accepted, it’s whether it’s accepted by the person you’re arguing with. And, again, what matters is whether you can find such principles to base your argument on, not whether the person you’re arguing with thinks those principles are matters of objective fact.
(“You shouldn’t eat that because it’s got lots of beetroot in it and you hate beetroot” is a strong argument even if the person you’re making it at isn’t a gastronomic realist. Similarly, “You shouldn’t do that because it would mean X and you regard X as morally bad” is a strong argument even if the person you’re making it at isn’t a moral realist.)
You can be a utilitarian and a realist, as well.
Of course! I thought that was obvious and I wasn’t in the least intending to suggest otherwise.
There’s very little difference in that distinction [sc. between dismissing something and disagreeing with it].
I completely disagree. Dismissing something is justified much less often than disagreeing with it; it’s often true to say “you can’t just dismiss X” but false to say “you can’t disagree with X”.
There can be truths about human constructs, e.g. Engineering, Economics.
Perhaps I misunderstood you, before. I thought you were talking about constructing an ethical system. The equivalent of that in engineering would be constructing a set of physical laws, but that’s not what anyone does when determining truths about human constructs in the realm of engineering; when an engineer says “if you build the bridge that way then it will fall down”, they mean it will fall down because that’s how the universe actually works, not only that we have invented a system of physical laws according to which the bridge will fall down.
Lack of universalism does not imply lack of realism.
Fair enough. But what you wrote does seem to me flagrantly non-realist, not merely non-universal.
It is not nihilism, or anything-goes subjectivism either.
Indeed it isn’t. But I thought you were making a claim stronger than “nihilism is bad”, and saying specifically that moral realism is necessary in order for there to be any point in engaging in moral arguments. Maybe you weren’t. You’ve talked about “relativism” and “subjectivism” and (non)”realism” and not been terribly clear about what distinctions, if any, you make between those terms; perhaps all along you were saying only “nihilism is bad” and this whole argument has been a waste of time.
If you think there is an actual disagreement here, then I beg you to do the thing I asked you to three years ago upthread: describe an actual concrete situation in which some moral argument should move a moral realist but there’s no closely-equivalent argument that should have the same effect on someone who has the same moral values but isn’t realist about them.
I think that if a moral argument moves someone it’s by appealing to specific moral values they have, and that this will work equally well whether they are realist about those values or not.
You don’t need to be a moral realist to be swayed by arguments from logical consistency. If I say “I regard animals as moral patients and therefore won’t eat them, but I do eat fish and chicken” then pointing out my inconsistency has much the same force whether I’m a moral realist who thinks “animals have moral importance” is a fact about the universe or a moral nonrealist for whom it’s a fact about my value
Such arguments could be realist arguments, even if the person hearing them doesn’t label themselves a realist.
What matters isn’t whether a principle is widely accepted, it’s whether it’s accepted by the person you’re arguing with
What matters for the purpose of this argument is what works better in general, because the point is that MR needs to be constructed if it doesn’t pre exist.
. I thought you were talking about constructing an ethical system. The equivalent of that in engineering would be constructing a set of physical laws
No, engineers get physical laws from phsyiscists. Engineering principles are tied to an end in a way that physics isn’t …you don’t engineer a sportscar the same as a haulage truck.
when an engineer says “if you build the bridge that way then it will fall down”, they mean it will fall down because that’s how the universe actually works, not only that we have invented a system of physical laws according to which the bridge will fall down.
It will fall.down because it is not following the right engineering principles, which are based on, but not wholly derivable from , the laws of physics. They are not wholly derivable because you need to know what you are aiming at it.
But what you wrote does seem to me flagrantly non-realist, not merely non-universal.
Does it seem relativist or subjectivist?
But I thought you were making a claim stronger than “nihilism is bad”, and saying specifically that moral realism is necessary in order for there to be any point in engaging in moral arguments
Constructivism, as I have outlined it, can give a point as well. I am not claiming full strength realism.
Maybe you weren’t. You’ve talked about “relativism” and “subjectivism” and (non)”realism” and not been terribly clear about what distinctions, if any, you make between those terms
There are a lot of possible positions, no way I can explain all of them from scratch, and no need to, since reference material is available. Read

Realism of the kind I.stalking about isn’t some weird thing that’s different from everything else. Logic, maths and game theory are objective. So someone who already accepts logical principles like “inconsistent things are wrong” and game theoretic principles such as “people are more likely to co operate with me if I cooperate with them”—and many people do—is already in a position where they can accept the kind of realist , or quasi realist, arguments I am stalking about. And many real-world examples.of mass persuasion—where a whole society has shifted—work that way.
Subjectivism can’t account for convergence , or global shifts, since any successful attempt by A to convince B can be cancelled out by some C convincing some D in the opposite direction.
Kinds of moral realism that depend on weird metaphysics aren’t going to successful in mass persuasion either. So that’s not what I.am.talking about.
Yes, the subjective argument works in the special case where someone ’s behaviour doesn’t jibe with their actions, and, no it still doesn’t have the potential work as well as objective arguments in any other case.
