If the objective morality that exists is "Existence should not be," it doesn't matter, that's what it is. I'm not debating that. Just like if the real morality is "Contradictions should be encouraged in life". If that's what it is, that's what it is.
What I'm noting is that if it is, according to itself, it shouldn't be.
For now? Morality is the analysis of what should or should not happen. Keeping to what should or should not be is moral, while going against the precepts is immoral.
The nature of objectivity is a rational deduction that persists despite differences in subjective experience.
The nature of subjectivity is a rational or irrational conclusion that relies on one specific subjective experience.
The guidance of objectivity is the understanding that there are certain conclusions which are apart from our desires or personal viewpoints. Meaning an objective conclusion has the potential to violate everything we wish and stand for.
The default child-like state is to believe that one's perspective is unalienably correct, and reflective of reality. Objectivity is meant to raise a person's thinking beyond this, while subjectivity is its contrast and reminder to be conscious of our own limitiations.
What is rational is to connect information together in such a way that is reflective of reality.
It is a judgement that accurately reflects reality.
Yes, but can you give an example of that 'something' that isn't a mind?
Contradicting a person's nature is not the law of non-contradiction.
Stating that something is self-evident doesn't demonstrate that its also not an equivocation though. If minds are not identical to ends-in-themselves, then we would need to see some difference between a mind and an end-in-itself. If you aren't seeing equivocation, could you note how they are not simply the same thing?
For me it is that I should value an end in itself beyond an opinion that I should do so. I see nothing concrete that binds me to it, or demonstrates a provable ethical decision
So then, its not an ontological necessity that if an objective morality exists, that it conclude 'Existence should be.' Its more that such a morality seems so at odds with itself and with our general sense, that it doesn't fit
4. For B to be true, it must not contradict itself B = B && B != !B
6. Because it is moral that 'nothing should exist' the reason should also not exist
7. But for 'Everything should not exist' we have a reason that does exist, that should not exist.
8. But if the reason should not exist, then it is immoral for the reason to exist. Thus B is false. !B
9. if the reason should not exist, then 'Existence should not exist' should not exist either. !B <-> !A
This is the part I'm not understanding. Can you clarify? What does must/should mean?
Correct, that's not the same as what point 2 is saying. Its an odd thing that I agree with practically everything you're stating yet I can't understand the overall point you're trying to make. :) We're almost there I feel though, so please keep trying.
3. If B is true, then B should not exist. B -> !B
Almost, but not quite. We're assuming if 'everything should not exist', [then] there must be a reason. Its not an identity.
“There must <...>” is the same statement as “There should <...>”: same issue. — Bob Ross
Now I'm confused. Didn't you just have an issue with me swapping 'should' and 'must' earlier? I agree you had that right. What should exist is not the same as what must exist.
Almost, but not quite. We're assuming if 'everything should not exist', there must be a reason. Its not an identity.
2. There must be a reason that everything should not exist
2. For there to be a reason that everything should not exist, some reasonshould[has to] exist [such that everything should not exist].
So if the truth of its own premise is that it shouldn't exist, but it must exist if it is to claim that it shouldn't exist, we're left with a contradiction
2. There must be a reason that everything should not exist
Reason's Greetings & Happy New Year, Bob! :sparkle:
If something is solely a means to an end, then it can’t be an end itself because it is just a means towards some other end. If it is also an end then it is not just a means towards an end. — Bob Ross
Repeating your definition doesn't make it more substantive than just a definition.
P2 notes that minds are ends in themselves, and this is because minds are the only beings with the nature such that they are their own end—i.e., they are an absolute end
Circular to the point of being tautological.
C: One should not treat a mind as solely a means towards an end, but always as (at least) simultaneously an end in themselves.
Again, this conclusion does not follow validly from your mere 'definitions' (& otherwise 'hidden premises' e.g. what is conceptually meant by "minds").
1. It is required to note that minds are ends in themselves because the identity of ‘an absolute end’ does not entail itself that those are only minds — Bob Ross
This is why I asked earlier if you could give an example of an end in itself that wasn't a mind.
Yes, this is my general problem with ethical theories and why I feel we have a lot more work to do on the matter.
Right, but that's the answer to any valid syllogism. If we accept the premises, then the conclusion must necessarily be so. Yes, proving that first is essential. But after its proven, the question becomes, "Can you prove that I should accept your premises?"
We can revisit this later. For now, I do not believe that one should be rational is a subjective moral judgement. But we have to get the base down first before we build to that. :)
2. For there to be a reason that everything should not exist, some reasonshould[has to] exist [such that everything should not exist].
7. if A should exist, then it claims that A should not exist.
…
9 But if A should not exist, then it cannot assert that it should exist.
A contradiction is clear if the assumption of X assumption leads to its own negation
If you still don't see it, can you point out why A does not negate itself?
According to your definition of subjective, everything is subjective Bob.
Please use the definition I've put forward for now. It doesn't mean I'm right, it just makes sure we're on the same page. We can discuss which definition should be used after we get through the meat of the argument first.
What do you mean by “rationally or logically countered”? If make a syllogism that is logically valid which contains a moral judgment, is that moral judgment thereby ‘objective’ under your view? — Bob Ross
If you can prove that it is so, then yes. Rationality and logic are the best reflective tools we have about reality. It is in my view, the only way we can meaningfully assess it. Meaning if you have an argument that is air tight rationally and logically, which means it cannot be contradicted by reality in any way, you have an objective moral judgement.
I'm wondering if the tie in of minds to things in themselves is this fallacy. My thinking was that if minds are the only things that are ends in themselves, you can just remove ends in themselves and just note that minds are simply the things on this planet which should be protected and encouraged. It just simplifies the argument.
As a simple solution its a nice thought, but I'm not seeing how we can develop any air tight means of measurement when tough moral choices come up. Its not anything you have to debate with me about, these are just musings to think about.
So if you accept that ‘one ought to be rational’ and that ‘minds are ends in themselves’ and that ‘sole means are not ends’, then it logically follows that one should not treat them as a mere means. — Bob Ross
I get that. The question is why anyone should care if a mind thinks its an end to itself
There's nothing requiring me in that argument to not solely treat them as an ends in themselves. All you've noted is that we cannot solely view them as a means.
Vice versa it also means we cannot solely view them as an ends.
Is it possible that you could demonstrate why using a person for one's own end is a contradiction?
I believe you need to include Kant's universizability principle for it work.
What if I also treat myself as a means to an end?
You are just subjectively stipulating that what one should do is what is rational, and then calling ‘objective’ whatever can be reached as a consensus by people committed to that subjective moral judgment. — Bob Ross
No, I'm just assuming you'll grant me rationality and logic are the best tools we have to measure reality. This is not an assumption I spelled out, but maybe I should have. If you want me to go into the question of whether we should or should not use logic, I can go into that as well. I leave that to you to decide if that is important at this stage or not.
Not a problem, I'll try again. If this is good, I'll likely edit the OP to make things clearer as well.
E. Assumption: There exists a reason that nothing should exist.
F. If that is the case, then according to the reason that nothing should exist, that reason should not exist. Thus a contradiction.
2. Rationality and logic are our best tools at identifying and reflecting reality as accurately as possible.
3. An objective morality would be a morality of what should happen that cannot be rationally or logically countered.
I see that as a problem considering that minds and their status are the fundamental lynch pin of your argument. Perhaps this could be answered if you define whether it is possible for something that is not a mind to be an end in itself.
I understand you don't want to use the word value, but almost anyone using the theory will. In the case of choosing what must be sacrificed for another species to live, there must be a rationale behind it. In your case if you want to avoid value, you may just want to say, "Whatever is stronger." So if an insect ate a human being, it would be merely due to capability and not that one is more valuable than the other.
I'm not seeing why that matters though. All this seems to imply is that minds are beings that are ends in themselves. It doesn't prove why anyone should value this, its just a claim.
…
Just why ends in themselves should matter beyond our desire or opinion that they should matter.
I appreciate the suggestion Bob, but I don't think I use any empirical claims. In fact, when we spoke about this last time I believe the point you noted was despite the logic of the claims, you were one of the only people who noted we lacked empirical fact to back it. I agreed with you then and still do today. The claim is not that it is empirically necessary that there be a first cause, but logically based off of the definition of a first cause vs an infinitely regressive cause.
The nature of morality is what 'should' happen. That's where we've started. As I examine proposals of what should be, I ask, "Why should that reason be?" until we chain all the way down to the basic question. "Should there, or should there not be existence?" That's really all there is to it at this point.
An objective moral judgement would be a moral judgement that can be logically concluded on no matter the difference in subjective viewpoint
…
This is something that cannot be rationally agreed upon by all people.
…
So, for a moral judgement to be objective, its 'should' must be rationally proven despite one's subjective viewpoint.
But if that existence should not exist, then 'nothing should exist' becomes 'nothing should not exist'.
This does not follow: why would this be the case? It is a non-sequitur, by my lights, to say ‘If the existence should not exist because nothing should exist, then nothing should not exist’. — Bob Ross
Because you're forgetting the first assumption:
1. There is an objective morality
Remember, we're not proving that an objective morality exists. We're stating, "If there is an objective morality, what must its foundation be?" And when we examine this down the chain of 'should's' we are left with the foundational question, "Should there, or should there not be existence?" This is a binary assuming that there is an objective morality. Meaning if one side is false, the other side is necessarily true. If both are false, then there is no objective morality. But that's not what we're looking for. We're saying, "IF, there is an objective morality, which way should the binary logically swing?" I hope that clears it up!
Please remove any vocabulary like state-of-affairs in your next reply so I can understand your point. As it is, I can request that as the OP. Feel free to keep any of your own vocabulary in your head, but translate it down to the language of what we're covering because you're not at where the argument is, you're somewhere else I don't understand.
Yeah Bob, I don't know what you're talking about. Please remove your own language and try to say what you want to say using the language I've put forward.
If something existed that noted 'nothing should exist' then that existence should not exist.
But if that existence should not exist, then 'nothing should exist' becomes 'nothing should not exist'.
ts very existence would be a contradiction
….basing metaethics on F.P.M.M, 1785, isn’t what that treatise is about. For ethical systems, you’d probably want Metaphysics of Ethics,1797, especially considering your sections on rights and virtue, each having a book of their own in that work as a whole
….the exchange of rational beings for minds either leaves out, or at least makes no account for the fundamental predicates of Kantian moral/ethical philosophy, re: will, autonomy and pure practical reason belonging necessarily to the former as a rational being, or person, but these need methodological justification in the latter as a simple mind;
….the conceptions means and ends, as they relate to moral/ethical philosophy, need to be determined before a FET with them as its ground, makes sense;
….you say, “FET, no matter how useful it is itself for ethics, cannot be enough for good moral discernment”, but I rather think the intent of it was precisely for moral discernment, of the pure subjectivist account.
….lastly, if one thinks ethics relates to a community of persons/minds, wouldn’t each mind need a moral disposition of his own? Otherwise, they become a hive rather than a community. And if that’s the case, shouldn’t there be some necessary condition similar to a categorical imperative somewhere in this current theory?
Anyway, I like the work that’s been done here, but it seems a little incomplete to me. I can’t help but think that upon more substance amended to the conditions, it may be found they don’t work as they are now.
The only potential problem I see is how to justify eating or using animals for materials or labor
Beyond animals, there's now also the question of insects. Do they have minds?
Where does a mind begin and end?
If we can't treat them as solely means, then do we have a right to eat them?
Why are animals and insects ends in themselves but clearly have less value compared to people?
The only issue is that P2: Person's are ends in themselves isn't proven, its more of a given assumption.
But it all hinges on the reader accepting that a mind is an end in itself and that ends in themselves matter. For a person who already agrees or does not want to question this, it can work.
I'm granting them as acceptably internally coherent.
Its not that I don't think minds are the greatest things that can be, its the 'end in themselves' argument that isn't enough for me. Why is it important to be a end in itself? What does that even mean? (I know you've answered this, just showing my thought process) Why is it that we have value and morality at all?
Is rationality different for me and for you? When you provide an argument you are assuming a common standard of rationality, and you are assuming that validity and soundness are the same for you and your interlocutor. Rational justification is similar.
The point here is, "Because I believe it," is not a rational justification (for you or for anyone else).
I have explained multiple times that I am contending the conclusion of your disjunctive syllogism.
For example, if you said, "I have reason to believe the car is not black, and I have reason to believe that the car is not not-black, therefore I have reason to believe that the car is neither," I would point to your conclusion and give arguments for why it is incoherent.
How does it contradict it Bob? I missed or misunderstood what you were saying then.
Why is it that the state of existence can never be a moral judgement grounded in the relevant state of affairs between existence and nothing existing?
The objective judgement would be the true decision between whether there should be existence or not right?
And we're talking about the arrangement in which there is at least one existence, or no existence
If morality is objective, then it is necessarily the case that “why should babies even exist?” is completely irrelevant to the truth that “one should not torture babies” as a moral fact. — Bob Ross
Why is it necessarily the case?
There's a very good reason I'm not using the term moral realism. It might not be true. At least, many of the tenants and contexts of it. When speaking about a foundation we should not be concerned where we are going. We're just concerned about noting the foundation first. If that is solid, we build from there. We might end up in moral realism, or not. We're starting super small first, so we assume nothing beyond it.
Lets take it in the reverse case. "if I grant morality is objective and reality has an objective moral judgment such that “something should exist”, then something should exist."
So far I've presented that its logically impossible for a reason to exist that existence should not exist. If you think this is wrong, then you must prove that there exists a reason that existence should not exist. If you can't, then we go by what we have remaining: logic.
Seems fine to me. Since this is based off of Kant, it might help to contrast your reasoning with why Kant chose rational minds. I explored Kant years ago and do not remember much at this point.
Also, an animal is not a person. So no need to go into any more detail for me.
So I think this is in a lot better place, I just noted two questions to consider.
1. Can you prove that any of us should care about people as ends in themselves?
2. Can you make a clear contrast with how Kant determines its rational beings to consider in the FET with your line of reasoning that it should be minds?
Other then that, I think its just Kant stuff, and I'm sure a Kantian will come along and be able to provide more feedback. Nicely done Bob!
Which just shows that because something is explicitly agreed to by citizens in a kind of "social contract" sense it doesn't follow that it is morally right.
That's fine, but I'm not seeing why that denies the foundational question of all 'should's' "Should there be existence or not?"
That's the definition of a foundation Bob. When there are no more questions and reasons to be given, you have a foundation. That must be proved.
Hypotheticals are a disengagement from the discussion that will go nowhere.
So I would simply ask, "Why is this proven objectively?" Then they would need to give me a foundational reason why
If I asked, "Why should babies even exist? If they don't exist, they can't be tortured." what would be the answer?
We're not talking about moral realism. We're talking about the logical conclusions one has to reach if an objective morality exists.
I don't understand what you mean by 'current reality'. There is either existence, or there is not. The question is should there be existence, or should there not. To say something should, is to have a reason why A is preferable to B.
This is a hypothetical again. No if. Is there, or is there not a state of affairs in which there should be nothing?
I understand from your point of view, but for the reader, its not relevant what your argument is here.
I could agree with you if you stated minds, which would include insects, animals, and potentially plants.
The only problem in the theory is proving why minds are invaluable. I happen to agree that minds are the highest values in existence, but for the theory to hold you'll need to prove why minds, even irrational ones, are priced right out of quantification.
1. Minds vs persons.
Can we justify killing an animal to eat it and survive if they are a means to us and an end to themself? If ends to themselves are invaluable, how do we justify killing and eating cows over killing and eating other humans?
The problem with removing value entirely is that questions of relative sacrifice no longer have any justification.
We have a room with 3 people. An unapologetic murderer, an unapologetic saint, and a regular person. They all must choose one of them to die for the other 2 to live. Currently, your theory has no means of stating that the murderer should be the one to die.
Anytime we run into a case that conflicts with what most people would innately feel is a simple moral choice and conclusion, the theory needs to clearly and persuasively explain why we should logically dismiss that conclusion.
How do we treat minds that believe the best end to itself, is to end other ends in themselves? Or believes it is rational that the worth of other minds can be quantified as less than its own mind?
Finally, after fully establishing how it minds and not persons that this theory applies to, I would study the general criticisms that people lobby against Kant and see if an how your theory answers or dodges those criticisms
If there is no objective morality, then there is no 'should' for anything
One can do anything. But should they?
I am noting that one could, which is what I thought your claim was: are you just saying that the word explodes into triviality if we do? Because I agree with that.
But this isn’t relevant to your claim: it was that all chains of reasoning biol down to “to be or not to be?”, which is clearly false if the chain of reasoning about “should I torture babies?” bottoms out at a platonic form. — Bob Ross
Can you prove that it is?
…
You're making an abstract thought experiment into a concrete proof.
If I can continue to ask why should Platonic forms exist, and that reason lies beyond Platonic forms, that is the continuation of the chain, not a new chain. A chain only ends when you arrive at a foundation.
This is the intention I'm trying to convey. If "One should help the sick, one should exist." "Well why should the sick be helped?" Because they should live. "Why should a person live?" And to answer that you must answer the question of, "Why should anything live?" And to answer that you must answer the question of "Why should anything exist?" You're looking up higher for the answers to the questions of why a castle should be built a certain way without first asking the question of why a castle should be built at all.
If it is the case that nothing should exist, then the reason, "Nothing should exist" should not exist. Thus the conclusion. It is a contradiction for there exist the reason, "Nothing should exist".
You may have forgotten the assumption that we're currently making. That is that an objective morality exists. This means that there is some foundation for 'should'.
"There is no fact that dictates God exists, but any sane person will agree to this judgement."
Claims like this beg challenges and can cause people to dismiss your claims outright. I'm not going to do that of course. I'm just noting that if you want to get to your point, you don't have to make claims like this. A simple "I'm not here to debate why one should choose the subjective start of, 'one ought to do what is rational.' I'm simply going to start with this and show a morality based on rationality." will work fine. So that's what I'm going to do. I'll assume that we take the prime assumption that we ought to act rationally and go from there.
P1: If something is solely a means towards an end, then it is not an end in itself.
P2: To value something entails it is solely a means towards an end.
C1: To value something entails it is not an end in itself. — Bob Ross
P1 is fine, but how do we get P2? Can I not value an end itself? If I valued world peace, would that not be the end of my means? Can you explain further what you mean by P2?
That is fine, but what if I don't value a mind? I'm assuming with the initial premise of "we ought to be rational" that "minds are rational, therefore they should be valued for they ought to be."
I'm a little confused by P5. Why are persons ends in themselves? Can't I use persons as means to my goals, even benevolently? If I send soldiers out to stop a terrorist, am I not using those soldiers, those people, as means to an end?
P1 merely highlights that if something is just a means towards some end (and just a means) then it cannot be an end itself—e.g., if mowing my lawn is a means towards making my house look presentable (and that being the only consideration), then mowing my lawn is solely means to an end and that end is making my house look presentable. P2 notes that persons (i.e., minds) are ends in themselves: persons are the only type of existence in reality which is capable of having ends and of being ultimately the final end for itself—e.g., although making my house look good may have been the end within the previous example’s context, it is likewise only a means toward another end (like making myself look respectable to my guests) but it will, without any consideration of other people as ends, ultimately bottom out at the final end of myself: I ultimately mow my lawn, in the case that I am not considering other people as ends, for myself—for my benefit. Persons are the only creators capable of setting out hypothetical imperatives (i.e., contextual ends) for the sake of themselves (as the final end) and are thusly ends in themselves. P3 simply notes that the stipulation of this ethical theory is that one ought to be rational which implies being logically consistent; and P4 demonstrates that treating a person as solely a means towards an end entails (at least implicitly) a contradiction and thusly should not be done (if one is rational): when one uses another person for solely their own end, they concede in action that the other person is not an end in themselves (because they are treating them as solely a means) but are equally conceding that they are an end in themselves (due to their nature as a person)—hence the contradiction.
That persons, and thus minds are means and not ends in themselves. This is because you haven't proven either of the statements, only asserted them. Still, lets continue and assume you can demonstrate C4 as true.
Again I'm going to assume minds have value because they are rational and therefore have innate value. So since we should not consider minds valueless, they have value. And since minds have value, people have value. But then doesn't this prove that people are not ends in themselves?
That we should consider that minds have value? Then why are we asserting that minds don't have value?
Are you stating that not valuing a mind with the representation of 0, is in fact a value? Because that just doesn't work Bob. The number zero is a representation of there not being a quantity. The number zero is not a quantity in itself. The number zero for value is a representation of there being no value, a numeric assignment of zero for value does not mean there exists a value. It means there is no underlying represented value.
Finally, the term 'invaluable' means that it has so much value, it cannot be quantified into one number. It doesn't mean it has no value at all.
I think you're trying to say something here, but its just not coming across correctly. It seems to me that when you speak about valuing something, you're talking about a quantative value. For example, lets say we valued a person's worth at 10,000 dollars. If of course we could value people quantitively, then we could use them as means to an end. For example, I could use a person worth 10,000 dollars to make myself 1 million dollars. However, if human value is so valuable as to be beyond quantification, an infinite value so to speak, then we could never use a human as a means to an end. We don't use infinite money to make infinite money, that's silly. We simply enjoy infinite money.
Is that what you were trying to say?
This seems to jive with your idea of your formula of ideal sovereignty. If all people are infinitely valuable, sacrificing one infinity for 99 infinities works in the moment of practical necessity, but one infinity is just as equivalent in value to 99 infinities, thus this sacrifice should be abated where possible.
namely that there is parity between the rational justification for an object's height, and the rational justification for a moral claim.
"True for me," or, "Rationally justified for me," is a nonsense assertion.
Again, if your moral claims do not even pretend to possess rational justification, then clearly your moral system is ridiculous. Your disjunctive syllogism has led you to an incoherent position.
Edit: The way out of this silliness is to recognize that there are certain universal and/or objective values, such as "suffering is bad" or "suffering should be avoided" (
↪Leontiskos
). Even Hume recognized this.
P1: If something is solely a means towards an end, then it is not an end in itself. — Bob Ross
This is a vacuous definition, not an ostensible claim.
P2: To value something entails it is solely a means towards an end.
Demonstrate this entailment.
…
C1: To value something entails it is not an end in itself.
Invalid inference from underdetermined "propositions". Ergo, "FET proof" (C6) fails.
P1: If something is solely a means towards an end, then it is not an end in itself.
P2: Persons are ends in themselves.
P3: One should abide by the law of non-contradiction.
P4: To treat a person as solely a means towards an end is to contradict their nature (i.e., to contradict P2).
C: One should not treat a person as solely a means towards an end, but always as (at least) simultaneously an end in themselves.
P1 merely highlights that if something is just a means towards some end (and just a means) then it cannot be an end itself—e.g., if mowing my lawn is a means towards making my house look presentable (and that being the only consideration), then mowing my lawn is solely means to an end and that end is making my house look presentable. P2 notes that persons (i.e., minds) are ends in themselves: persons are the only type of existence in reality which is capable of having ends and of being ultimately the final end for itself—e.g., although making my house look good may have been the end within the previous example’s context, it is likewise only a means toward another end (like making myself look respectable to my guests) but it will, without any consideration of other people as ends, ultimately bottom out at the final end of myself: I ultimately mow my lawn, in the case that I am not considering other people as ends, for myself—for my benefit.

Defending your society if invaded is a very different matter than conscription to fight in wars that are based on political alliances. The point really is that just because some ethos is entrenched in societal law, on what we might want to refer to as " the social contract", it certainly does not seem to follow that it is therefore somehow objectively, or even inter-subjectively, validated.
Not a problem! I greatly respect your work and try to give it its full due. I have noted in the past that it is something I greatly appreciate you having done with me in the past. It is the least I can do!
Ah, here it is Bob! I almost missed it. We've already discussed at length on the meta-ethical considerations, but I will dismiss them here.
The thing in itself is objective. Truth as forever unknown to us is a thing in itself. Truth as known to us is subjective, and is at best an approximation that can never be known in the objective sense. The best way to subjectively know truth is to make a judgement that is not contradicted by reality.
To me, I do not see a separation between the two with your definition of subjective. If everything we judge is mind dependent, then all moral judgements are subjective (in the fact we make them) and all moral judgements express something subjective (in the fact we make them). Since what is objective is mind independent, there is nothing we can say, do, or judge that is objective, as it is all subjective.
…
As you have defined subjective, if there is even an iota of mind dependency, its 100% subjective.
I really should have used another word, falsifiable. If you are making a claim that something is true, it must also be falsifiable to be considered seriously in application
So in what case is your falsifiable claim that moral decisions are true based on our psychology?
For something to be permissible, something else must be impermissible
A subjectively true moral judgement must at some objective level, correlate with reality. This is best known when reality does not actively contradict us.
Why even use the word 'should' at that point?"
So for example, "Platonism is True because of A. It should exist because it is necessary that Platonic forms exist, and there is no other possible option." If of course there are other options other than Platonic forms, then the chain continues. If you're not seriously demonstrating Platonic forms are the foundation of 'should', just understand we're using "Platonic forms" as an abstract X for a thought experiment about the foundation of 'should' to help you understand the chain.
But we're not talking about what one should do at this point. That's a few steps away. We're just talking about the foundation of good if morality is indeed objective.
I never claimed that there was a contradiction.
Do you actually believe that moral claims are true in virtue of beliefs? That is the question. I don't think you even believe yourself.
But, "No one should torture babies," is not self-referential. It is referring not just to oneself, but also to 8+ billion other people.
I have provided an argument: "Because I believe it to be so," is not a rationally justifying statement.
If this is so then your response is not a (rational) justification. It does not rationally justify. Beliefs do not rationally justify moral claims. You admit that more is needed.
