My 'system', as you call it, rests on the existence of features of reality that are or were the case, whose existence and nature are independent from anyone's opinion or description of them. In short, I'm a (at least methodological) realist. If you want to argue about ontology, we can certainly do so. But I assume that, if you think there's no way to distinguish between what we call facts and what we call opinions, you at least understand what the things we call facts and opinions are.
So you still haven't given any justification for your claim that facts are different from opinions. After asking you three times, the absence of an answer is disconcerting. Apparently you don't have any way to differentiate them.
Epistemology (theory of knowledge) is a complete - though, for some of us, entertaining - waste of time. What we call knowledge isn't a thing of some kind that exists somewhere, somehow, and that can therefore be described. That's an ancient metaphysical delusion. Knowledge and 'knowing things' are what we say they are. How could they be anything else?
I'm clear on your ontology. What's at issue here is epistemology. Your claim is that objective moral "oughts" are epistemically impossible. I say that your system has the exact same problems, and that your "facts" are epistemically impossible. Once enough opinions agree on one thing do we call it a fact? Because if that is so, then there are moral facts, too, for some moral opinions converge. Or is there some other way to differentiate an opinion from a fact? You seem to think we can't get to moral facts from moral opinions. I am wondering how we get to natural facts from natural opinions?
I make a sharp distinction between features of reality (facts) and what we believe and know about them. Do you think the chemical constitution of water is a matter of opinion? Do we think there can be rational disagreement about the fact that water is H2O? The impossibility of objective moral oughts has nothing to do with knowledge. It's a matter of their non-existence as features of reality.
Those constitute reasons justifying the factual assertion that water is H2O. But your idea that the assertion itself implies an obligation to agree with it is simply false. Nobody is obliged to agree with any assertion, factual or non-factual. You've made that up.Peter Holmes wrote: ↑August 1st, 2021, 4:24 amI didn't say a single word about an assertion. You say people have no obligation to believe that water is made up of H2O. I say they do. I say they ought to believe that water is made up of H2O.Leontiskos wrote: ↑July 30th, 2021, 1:38 pmYou don't think that other people ought to believe that water has two hydrogen atoms and one oxygen atom? When they claim that water has three hydrogen atoms they aren't doing anything wrong? That's a strange idea.What I think people ought to do in response to a factual assertion is irrelevant. The assertion itself has no intrinsic 'ought' component. You've made that up.
The reason the obligation arises could be several: investigation, arguments from authority, accepting the common opinion, etc.
Not so. I've given a clear argument for the functional difference between the falsifiable factual assertion 'this is a tangerine' and the unfalsifiable non-factual assertion (say) 'capital punishment is morally wrong'. And the evidence for the functional difference is that, given the way we use the words involved, 'this is a tangerine' is falsifiable - because, if it's an apple, the assertion is false. Whereas 'capital punishment is morally wrong' is unfalsifiable, which is why it's rationally possible to accept or reject that moral assertion. The moral rightness/wrongness of capital punishment is nothing like a tangerine. I wonder why this is so hard to grasp.My challenge stands: what is the difference between the presumptive "ought" and the conventional moral "ought"? As noted, you are begging the question. You are giving no argument for your assertion that they are different.So now you're admitting that it is an "ought," but claiming that it is a different kind of "ought." Yet to say that it is different because it is about a tangerine begs the question. My whole purpose in introducing the tangerine was to show that it is not different. They are both "oughts." And you deferred your opportunity to define what you mean by "ought," so my argument stands. You will have to give some reason or argument for your assertion that they are different.Read more carefully. You imagine an ought attaches to a falsifiable factual assertion - but it doesn't. My point is that the assertion 'you ought to believe this is the case' - which contextually has a use - is completely different from the assertion 'you ought/ought not to do that'. So you've invented an implied obligation in a factual assertion, and conflated it with the obligation stated by a conventional moral assertion.
This is just wrong. The conclusion of a valid and sound factual argument isn't an 'ought' in any way whatsoever. The claim that it ought to be accepted is entirely separate and unconnected.
If I did say that, I apologise. Do you have the quotation?{quote]The basic inference is as follows, in a few different forms:Your three premises are false, or not shown to be true. Each contains an 'ought', which, obviously, begs the question as to entailment from an 'is'.{quote]
Obviously the claim, "This is a tangerine," is purported to be true, and therefore ought to be believed by the sister (at least as far as the brother is concerned).
- If something is true, then it ought to be believed.
- If something is shown to be true, then it ought to be believed.
- If an argument is sound, then the conclusion ought to be believed (because it is true).
I want to focus on the third form, which is about argument and soundness. Above you claimed that truth and belief/acceptance are equivalent.
I think they come apart a bit, and this is seen in formal arguments (but even if they don't the obligation still attaches to the conclusion). Take any argument:
In an argument the conclusion is virtually but not formally contained in the premises. Or, the conclusion is implicitly but not explicitly contained in the premises. What an argument is actually doing is taking accepted premises and showing that they lead ineluctably to a previously unaccepted conclusion. A successful argument will make use of premises and inferential rules that are already accepted by the interlocutor (these are the "is" parts), and it will move to a conclusion that was previously rejected by the interlocutor, but that they will now be forced to accept due to the obligation placed upon them (the conclusion is the "ought" part).
- Premise 1
- Premise 2
- Conclusion
The conclusion of a sound argument ought to be believed in virtue of its truth. For someone to accept the soundness of an argument and reject its conclusion would be for them to abandon their obligation to truth and logical consistency.
This description of deductive inference is correct. Well done. Now, please produce an example of a valid and sound argument with a factual (is) premise, or factual (is) premises, and a morally judgemental (ought) conclusion. That's all you have to do. (Whether the rest of us ought to accept the argument is an irrelevant and completely separate issue.)No, whether "the rest of us ought to accept the argument" is precisely what is at stake, because if I give a concrete argument that need not be accepted you will immediately claim that it is not universally obligatory. This being the case, I already gave the argument, you're just uncomfortable with the level of abstraction. To repeat myself, "A successful argument will make use of premises and inferential rules that are already accepted by the interlocutor (these are the 'is' parts), and it will move to a conclusion that was previously rejected by the interlocutor, but that they will now be forced to accept due to the obligation placed upon them (the conclusion is the 'ought' part)."[/quote]
Nope, this analysis is wrong. And anyway, this supposed obligation to accept the conclusion of a valid and sound argument has nothing to do with a supposed moral obligation to do or not to do something.
QED. You're free to accept or reject my argument. There's no obligation. And this is all a red herring anyway.
Sound or obligatory arguments are always person-specific. If you are able to present an argument to your interlocutor that they believe to be sound, then they must accept the conclusion. That is, they are obliged to accept the conclusion. This is the relevance of the three conditionals I gave above. Each of them illustrate the nature of the obligatory inference. Again, the punch-line is that if you believe an argument is sound then you have an obligation to believe it.
So what's an example? What you are doing right now is an example. You are trying to convince me that morality is not objective. All you are trying to do is present an argument that I agree is sound. You are not trying to convince me that I must accept sound arguments. If we get to the end of this and I say, "Well, I accept that all of the premises of your argument are true, and I also accept that all of your inferential reasoning is valid, but I still reject your conclusion," what would you say? You certainly would not go on arguing. You might say that I am intellectually dishonest, or that I am engaging in bad faith, or that I am not a real philosopher, etc. At root I would be failing my obligation accept truth where it is found. To accept an argument as sound and to reject its conclusion is to fail one's obligation to truth, and the very fact that you are engaging with me presupposes this obligation. If you didn't think I had an obligation to accept sound arguments you would stop engaging immediately.
I may be confused - but I reject your earlier hypotheticals. And I don't see how they have anything to do with the claim of moral objectivity.
So we are at the hypothetical stage of my argument. I gave conditional inferences. If you admit that an argument is sound, then you are obliged to accept the conclusion. Obviously you think the hypothetical obligation is insufficient to prove my point, and hopefully you will tell us why, but are you at least willing to admit that this hypothetical obligation exists?
Oh, okay. 'Propositional truth'? Well, propositionas don't exist. They're misleading metaphysical fictions. So the expression 'propositional truth' is dead in the water, as is the expression 'propositional knowledge'. In this context, the only features of reality that have truth-value - can be true or false - are factual assertions, such as 'this is a tangerine' and 'water is H2O'. And those factual assertions have truth-value because they assert things about reality that may or may not be the case - which has nothing to do with language whatsoever.That's largely correct. Kantian moral objectivists believe that there are universally binding moral "oughts" that exist independent of desires and goals. GEM has argued that there are hypothetical instrumental "oughts" that are not universal and are dependent on desires and goals. I don't think he has claimed that there are "moral facts." Indeed, he even eschewed the adjective "moral."But there are two questions, and you keep shifting back and forth between them. The first question is whether there is an objective "ought." The second question is whether IOF is true. GEM was arguing against IOF, not in favor of objective obligation. Just because an "is" can be derived from an "ought" does not mean that there must be universally binding and knowable "oughts."As I see it, the question is: are there moral facts? (Because only the existence of moral facts could make morality objective.) GEM's answer is yes, there are moral facts, because moral oughts are nothing more than instrumental deductions from goals - which is not what moral objectivists claim.
As it happens, I think an ought can't entail an is, just as an is can't entail an ought. But that's a separate argument.Sorry, that was just a typo on my part.
Ours is about whether a moral assertion (an ought) makes a falsifiable factual claim about reality. You say it does, but that knowing the answer is just a lot harder that knowing whether a claim about a tangerine is true or false. And I think your moral cognitivism is incoherent. We can never know if abortion is or isn't morally wrong - and claiming that we can is absurd - in effect, a category error.Nothing in what you say here surprises me, but my conversations in this thread are separate. I am engaging you on exactly two points: 1) Whether your system can support scientific objectivity; and 2) Whether propositional truth involves obligation. I haven't raised the "moral" question with you at all. That is intentional given my reading of your exchanges with folks like CIN and GEM.
Er, again, I am talking about propositional truth. That's all I've ever been talking to you about. The question of propositional truth is converging with regard to universality and IOF. I haven't engaged your "moral" argument at all, which I think is largely confused. The two issues that I have been pursuing with you will lend clarity to the "moral" question, but I have no need to beat the dead horse that GEM and CIN helped kill. We don't have to repeat that.In our discussion the two questions happen to be converging, the the convergence isn't necessary.Okay, stick to the existence of moral facts. Please produce one, and show why it's a fact (a feature of reality) and not a moral opinion about a feature of reality. It really is that simple. You could win the argument for moral objectivism at a stroke. Stop dodging.
Nothing in reality can verify or falsify an 'ought' assertion, such as a moral one, because it expresses a judgement, belief or opinion that I/people/all of us make or hold. For example, we can explain why we think people ought to be kind, but we can never show it's a fact that people ought to be kind. End of.
