So, let me clarify. You're going with: "'X is self evident because it begs the question' does not beg the question if I cannot justify X"?Not if there is no other way to justify it. — Samuel Lacrampe
(1) is a red herring; not being evidenced in no way suggests self-evident. (2) is an appeal to popularity.A claim is self-evident if (1) it cannot be evidenced (i.e. justified) by anything else, and (2) if everyone believes it to be true by default — Samuel Lacrampe
Me? Absolutely! It would go something like this. QM is well evidenced. A popular theory that grants indeterminism, on analysis, really only becomes indeterministic per application of the BR. But said application is strange. When Schrodinger has his cat in a box, per this story, we're supposed to use a particular rule to describe the box contents... the cat is in superposition. But when Schrodinger opens the box, we use a different rule... the box's wavefunction collapsed. That seems wrong... introduce Everett. Let's say we put Schrodinger and his cat-box in a bigger box now, shut the lid, and have Everett describe this system. How is he supposed to describe it? According to the rules he should describe it the same way Schrodinger describes the cat in the box contents... Schrodinger is in superposition. But Schrodinger, inside this box, describes the same thing differently... well, sort of. There's a portion of the wavefunction where Schrodinger describes seeing the live cat, and another where he describes seeing the dead cat, and these two are in superposition. But each of these reports a collapse of the wavefunction. So is something really collapsing? BR seems redundant and unreal; it introduced bigger issues. So let's just toss it out; instead of thinking that us "Everett's" are part of "the world", imagine we're just parts of a bigger universal wavefunction. Now SE is all that really happens; the rest is just what that wave function looks like to Schrodinger, and to Everett. Given that only the SE is real, since there's no indeterminism in the SE, the universe must be deterministic. Maybe there's a deeper principle like this, where everything happens for a reason.Now can you think of a way to justify the PoSR without begging the question? — Samuel Lacrampe
You're responding to the so what.So what? — Samuel Lacrampe
What use would that have? By contrast, embracing LNC and denying PoSR would have the use:Why should we not believe in the PoE or that 2=5, if not because it violates the law of non-contradiction? — Samuel Lacrampe
...of modeling the randomness possibility. I've asked this as a question, now I'll rephrase this. You should be interested in all of the possible ways you can be wrong. It is suspicious for you to propose to be interested in truth but not be interested in such things.(1) There are only 3 possible explanations for all events: determinism, free will, and randomness, as so: — Samuel Lacrampe
That's not a problem but it doesn't help you. A floor that can support 20kg ipso facto can support 10kg; these two things are not alternates, they are counterfactuals. Note that both can be true for the same floor at the same time, regardless of whether there's a 20kg weight on it, a 10kg weight on it, or neither. But a man who poaches an egg cannot scramble that egg and vice versa. So if this man does poach an egg, but "could have" scrambled it, it's not true that the egg was scrambled. Those are alternates. If that man's free will does lead to poaching the egg, but could have led to scrambling it, then we can't say the man's free will is sufficient to poach the egg. (Unless you want free will possibilities that are counterfactual; but such being consistent with determinism, that implies compatibilist free will, which stops dead steps before your soul conclusoin).This is not how I interpret sufficiency. E.g. Observing that a floor can support a 10 kg weight is sufficient to conclude that it can support 10 kg or less; but it could also support more. But maybe you can give me an example of what you mean by [sufficiency?]? — Samuel Lacrampe
I don't understand your statement; can you rephrase it another way? Otherwise if it helps, begging the question to defend a claim does not entail that the claim is false. It actually means the claim is not a self-contradiction, which is a good thing.So, let me clarify. You're going with: "'X is self evident because it begs the question' does not beg the question if I cannot justify X"? — InPitzotl
(1) The term "self-evident" literally means "evidenced by itself". You don't see it? Similar to how the term "Triangle" has the words "tri" (three) and "angle" in it.(1) is a red herring; not being evidenced in no way suggests self-evident. (2) is an appeal to popularity. — InPitzotl
Your lengthy paragraph seems to be an attempt at giving an adequate reason to justify the PoSR. Now if that reason is inadequate, then it fails to justify the claim; and if it is adequate (or in other words sufficient), then it presupposes the PoSR, that is, it begs the question.Me? Absolutely! [...] — InPitzotl
To claim that the alternative to the LNC has no use that you see, does not prove the LNC to be true.What use would that have? — InPitzotl
I am. You just haven't shown how I was wrong yet, since we are still arguing about the PoSR. Of course, I trust your comment applies to you too.You should be interested in all of the possible ways you can be wrong. — InPitzotl
Sure; but so what? Free will means that before the choice is made, there are numerous possibilities, like poaching and scrambling. As you wrote, before choosing to poach an egg, the man "could have" scrambled it.So if this man does poach an egg, but "could have" scrambled it, it's not true that the egg was scrambled. — InPitzotl
Follow the quotes back.I don't understand your statement; can you rephrase it another way? — Samuel Lacrampe
Self evident means something that does not need to be demonstrated.The term "self-evident" literally means "evidenced by itself". — Samuel Lacrampe
I see a perfectly rational way to deny PoSR.You don't see it? — Samuel Lacrampe
While I can appreciate the meta-ness of argumentum ad populum defenses of argumentum ad populum, it does nothing for me. The popular opinion was wrong in the past... there's no reason to believe it has any unique access to truth. "If a million people believe a foolish thing, it is still a foolish thing." Ambrose Bierce.When a claim cannot be evidenced any other way, then the appeal to popularity is sufficient to tip the scale in its favour. — Samuel Lacrampe
Who said anything about adequate, except for you just now?Your lengthy paragraph seems to be an attempt at giving an adequate reason to justify the PoSR. — Samuel Lacrampe
I'm perfectly okay with that. So it's inadequate. But it's a justification.Now if that reason is inadequate, then it fails to justify the claim
But you're the one bringing up proving that LNC is true, not me. For me, it's enough that it's useful. Paraconsistent logics may also be useful. A system with PoE isn't "bad" because it lacks LNC; it's "bad" because everything is both true and false, which suggests that truth and falsity have no meaning. That's good enough for me; if it's not good enough for you, fine. Demonstrate a (non-vacuous) use for a system with PoE in play.To claim that the alternative to the LNC has no use that you see, does not prove the LNC to be true. — Samuel Lacrampe
But you're not. You just changed "possibly wrong" to "shown how I was wrong". Those are entirely different things.I am. You just haven't shown how I was wrong yet, — Samuel Lacrampe
Ways you have established that I can be wrong, so far:Of course, I trust your comment applies to you too. — Samuel Lacrampe
Free will being a sufficient reason for any of those possibilities means that's the only possibility. Go back to randomness... if a collapsing wave function (CWF) causes the photon to go left, as a result of Born Rule application which specifies a 50% probability of doing so, it still factually goes left. I might incorrectly say, if it goes left, then the CWF was a sufficient reason for it to go left; but if it goes right, then the CWF was a sufficient reason for it to go right. That would be incorrect because it would be a redefinition of sufficiency to the degree that it becomes meaningless. But under such redefinitions, randomness would follow PoSR. See how that works?Free will means that before the choice is made, there are numerous possibilities — Samuel Lacrampe
But everything needs to be demonstrated ... as per that one principle called PoSR :joke:.Self evident means something that does not need to be demonstrated. — InPitzotl
A justification is defined as "showing a claim to be right" (source). So it cannot be inadequate.So it's inadequate. But it's a justification. — InPitzotl
True, but I see no better way to pick one first principle (or axiom) vs its opposite. E.g. some people may not believe in the LNC, and be very consistent in their beliefs (ie they contradict themselves), and I see no way to refute them other than to show it's a very unpopular belief."If a million people believe a foolish thing, it is still a foolish thing." Ambrose Bierce. — InPitzotl
I have provided a justification for the PoSR, namely, that it is a self-evident principle.I have no particular opinions on PoSR, except that you're flat wrong about it not needing justification. — InPitzotl
Recall that you denied that "the LNC is self-evident because it cannot be evidenced by anything else", by attempting to justify it in another way. Since this has not been accomplished, my position on the matter stands, namely that the LNC is self-evident, in a similar manner as it is for the PoSR.But you're the one bringing up proving that LNC is true, not me. For me, it's enough that it's useful. — InPitzotl
You may give it a try. Just remember that "The principle of sufficient reason states that everything must have a reason or a cause", and to justify is to give a good reason.(d) one need not appeal to PoSR to justify it. — InPitzotl
What is this random mechanics, and what's your justification to claim it exists?IOW, all of your claims of PoSR being self evident are trivially refuted by the mere possibility of considering random mechanics. — InPitzotl
As per underlined, why is that the case? I suspect you have a wrong grasp of the term "sufficiency". Just because A is sufficient to cause B, it does not follow that A will necessarily cause B every time.Again, it's really, really simple. It boils down to a single question... how many things can your free will decision possibly result in? If you say one, it's a sufficient reason for that thing, but you can't prove we have a soul. If you say more than one, it's not a sufficient reason for whatever happens, and you can't say it follows PoSR. — InPitzotl
No, that was a correction, not a claim. I responded to your definition of self-evident, which was based on armchair lexicography (some misguided "definition-by-literal" theory you invented), with the accepted definition. By the way, atom literally means indivisible; awful literally means full of awe; pompous literally means having magnificence.But if you are serious with that claim — Samuel Lacrampe
At least you're using a dictionary now, but you're over-interpreting "show". Also a dictionary isn't a great source for this (dictionaries document how words are commonly used; we're discussing terms in philosophy, which isn't a lay subject... though I could defend my definition this way anyway). What you need is a philosophy based reference that discusses this particular usage, like IEP:A justification is defined as "showing a claim to be right" (source). So it cannot be inadequate. — Samuel Lacrampe
Further still, true belief may not even be necessary for justification. If I understand Newtonian physics, and if Newton’s arguments seem right to me, and if all contemporary physicists testify that Newtonian physics is true, it is plausible to think that my belief that it is true is justified, even if Einstein will eventually show that Newton and I are wrong. We can imagine this was the situation of many physicists in the late 1700s. — Internet Encyclopedia of Philosophy
No method is better than a bad one.True, but I see no better way to pick one first principle (or axiom) vs its opposite. — Samuel Lacrampe
Might I suggest it more rational to give up your view that winning debates is a metric of truth than it is to embrace logical fallacies as a method of winning debates?E.g. some people may not believe in the LNC, and be very consistent in their beliefs (ie they contradict themselves), and I see no way to refute them other than to show it's a very unpopular belief. — Samuel Lacrampe
I don't recall that because it never happened. First off, begging the question isn't wrong on the condition that I provide an alternative ("by attempting"...); it's wrong on the face of it. To say "LNC is self evident because it cannot be evidenced by anything else" is to say "X is self evident when X cannot be evidenced by anything else", and if that were true for X=LNC, it would have to be true for X=an invisible massless cow is eating invisible massless grass in the middle of the sun. Second, I didn't justify the LNC being "true"; in fact, I explicitly pointed out a case where it wasn't "true" (paraconsistent logic). Third, it's not my rule that I should be able to prove things are self-evident; it's your rule. My rule is simply that things aren't self evident just because you wish them up to be by committing logical fallacies out of desperation to win arguments against hypothetical deniers. But I do have an applicable rule; one I've mentioned before. Any referential claim (by which I mean something about the properties of or behaviors of an object to which you refer) requires justification (i.e., the don't-tell-God-what-to-do principle). PoSR falls into this camp.Recall that you denied that "the LNC is self-evident because it cannot be evidenced by anything else", by attempting to justify it in another way. — Samuel Lacrampe
By that criteria, both LNC and PoSR are not self-evident, because you commit three logical fallacies when debating a hypothetical denier of both. Your logical fallacies are invalid defenses of these things being self-evident, since they are, well, logical fallacies. So since you failed to refute the denier's position, the denier's position stands...namely, that neither LNC nor PoSR are self-evident. Not quite a checkmate, but definitely a stalemate. I mentioned this before, too; debates cannot be criteria for truth because I can easily construct conflicting irrefutable arguments. Only here, you actually provided the conflicting irrefutable argument (well, mostly; I just tweaked it slightly).Since this has not been accomplished, my position on the matter stands, namely that the LNC is self-evident, in a similar manner as it is for the PoSR. — Samuel Lacrampe
That's the wrong question, with the wrong burden. Random mechanics involves a process whereby an event happens as a stochastic selection among a set of possibilities, such as by application of the Born Rule. Your claim is that PoSR is logically self-evident. Logic implies necessity. If random mechanics were possible, that would suffice to refute necessity. Random mechanics is possible. Therefore PoSR isn't necessarily true. O/c, this is insufficient to disprove PoSR; PoSR still could be true. It's just that, if it is true, it's contingently true.What is this random mechanics, and what's your justification to claim it exists? — Samuel Lacrampe
By definition of sufficiency.As per underlined, why is that the case? — Samuel Lacrampe
Then you're wasting your words... "proof by suspicion" is not valid.I suspect you have a wrong grasp of the term "sufficiency". — Samuel Lacrampe
If A can cause B, but B doesn't always happen, then in those cases where B does in fact happen, A is (maybe) a reason for B. For example, if a car swerves into my path while I'm driving, and as a result we have an accident, then the car swerving into my path is a reason for the accident. But cars swerving into my path don't necessarily cause accidents every time; I may see the car swerving and swerve to avoid it. But because it doesn't necessarily cause accidents every time, that reason is not sufficient to cause an accident. That's what you have here... A that causes B, but only sometimes. Such, given B, can be a reason for B, but cannot be a sufficient reason, because B doesn't always follow.Just because A is sufficient to cause B, it does not follow that A will necessarily cause B every time. — Samuel Lacrampe
You are using the common use definition as opposed to the philosophical definition. Better reference is here. But this doesn't matter. Let's use the term "First Principle" or "Axiom" if it makes things clearer.definition of self-evident — InPitzotl
This does not invalidate my point that justification means "showing a claim to be right". Before Einstein, that belief was justified because Newton's demonstrations were believed to be right. Once Newton's demonstrations were no longer believed to be right after Einstein, then we would no longer have a justification for them. To loop back, you cannot have an "inadequate justification".true belief may not even be necessary for justification. If I understand Newtonian physics, and if Newton’s arguments seem right to me, and if all contemporary physicists testify that Newtonian physics is true, it is plausible to think that my belief that it is true is justified, even if Einstein will eventually show that Newton and I are wrong. We can imagine this was the situation of many physicists in the late 1700s. — Internet Encyclopedia of Philosophy
The method is not "bad" but "weak-yet-valid". In a situation where we cannot remain agnostic, then it is more reasonable to side with the popular belief than against it. So a weak-yet-valid method is better than no method.No method is better than a bad one. — InPitzotl
I give you an equally non-rational and rhetorical response: I suspect you deny the PoSR, and the effectiveness of debates, and the criteria for first principles because believing in the soul is an inconvenience. :halo:Might I suggest it more rational to give up your view that winning debates is a metric of truth than it is to embrace logical fallacies as a method of winning debates? — InPitzotl
You forget that "self-evidence" (or first principle if you will) has 2 criteria. (1) cannot be evidenced by anything else, and (2) is the popular belief, or its opposite is absurd. You are missing criteria (2).it would have to be true for X=an invisible massless cow is eating invisible massless grass in the middle of the sun. — InPitzotl
Your argument is valid IF paraconsistent logic is true, that is, we observe that some objects behave in a way that does not follow classical logic but paraconsistent logic. Otherwise, this paraconsistent logic is merely a thought experiment.Second, I didn't justify the LNC being "true"; in fact, I explicitly pointed out a case where it wasn't "true" (paraconsistent logic). — InPitzotl
It is indeed my position, that I have defended with an argument, and it stands until the argument is refuted.Third, it's not my rule that I should be able to prove things are self-evident; it's your rule. — InPitzotl
Is this different from the PoSR?Any referential claim (by which I mean something about the properties of or behaviors of an object to which you refer) requires justification — InPitzotl
What three logical fallacies?By that criteria, both LNC and PoSR are not self-evident, because you commit three logical fallacies when debating a hypothetical denier of both. [...] — InPitzotl
Why do you claim random mechanics is possible?If random mechanics were possible, that would suffice to refute necessity. Random mechanics is possible. Therefore PoSR isn't necessarily true. — InPitzotl
Do you not see yourself appealing to the PoSR every time we enquire about what is true?that would suffice to refute necessity [...] O/c, this is insufficient to disprove PoSR — InPitzotl
Are you perhaps conflating the terms "sufficient" with "necessary"? Otherwise, what is the difference between the two terms for you?But because it doesn't necessarily cause accidents every time, that reason is not sufficient to cause an accident. — InPitzotl
Nice try, but the definition I use aligns well with the definition given by your source, and poorly with your linked to "common" definition. And your definition-by-literal definition doesn't seem to fit at all.You are using — Samuel Lacrampe
Not much of a difference; axioms (in philosophy) are statements presumed to be self-evident.Let's use the term "First Principle" or "Axiom" if it makes things clearer. — Samuel Lacrampe
It invalidates this point:This does not invalidate my point that justification means "showing a claim to be right". — Samuel Lacrampe
justified" means you have sound argument for why it is true — Samuel Lacrampe
But Newton's equations weren't "true"; they were just close. So Newtonian physics wasn't "sound", it was just justified. But the beliefs weren't justified because the demonstrations were believed (this isn't a chicken-and-egg game); they were believed because they were justified by being demonstrated.Before Einstein, that belief was justified because Newton's demonstrations were believed to be right. — Samuel Lacrampe
Einstein predicted the location of a star in the famous 1919 eclipse. Once the eclipse happened the star was observed to be in the predicted spot. That justified belief in relativity.Once Newton's demonstrations were no longer believed to be right after Einstein, then we would no longer have a justification for them. — Samuel Lacrampe
But that's superfluous, since all "adequate" means is enough to convince you. That one star observation was enough to convince a lot of people. Some people wanted more. To this day there's doubt that relativity is "true", since QM and GR haven't been melded together yet (and since in addition there are singularities).To loop back, you cannot have an "inadequate justification". — Samuel Lacrampe
To me that looks like an argument from ridicule with a tu quoque fallacy thrown in for good measure. That's quite a great distraction from, you know, actually defending the point in question... which, here, is, how is committing three fallacies to argue that a thing is self-evident going to help in your goal to convince the LNC denier that he shouldn't deny the LNC?I give you an — Samuel Lacrampe
Begging the question, appeal to personal incredulity ("I see no better way to..."), appeal to popularity.What three logical fallacies? — Samuel Lacrampe
Can you point to, or write, a philosophical paper that adequately justifies the belief that wavefunction collapse is unreal?Is this different from the PoSR? — Samuel Lacrampe
No, just dealing with question begging separately. The appeal to popularity doesn't help; miasma theory, phlogiston, vitalism, spontaneous generation, all were popularly believed. We know people spread urban legends, because we have inventories of them. Cult personalities and propaganda run rampant; group think is a thing, Milgram is a thing, Dunning-Kruger is a thing, cultural differences is a thing. The only situations where popular opinion is trustworthy are those in which you have some other justification (at a minimal, the specific situations in which you have good reason to believe the populace itself is justified); in such cases, you have a valid justification other than "everybody else thinks its true". Two wrongs just make two wrongs.You forget that "self-evidence" (or first principle if you will) has 2 criteria. — Samuel Lacrampe
In this "productive" debate, that tiny little phrase is actually rational. Begging the question, appeal to personal incredulity, and appeal to popularity are just as garbage as they ever were, and will always be as garbage as they always were. But reductio ad absurdum? That can actually be a valid argumentation technique. This is a glimmer of actual rationality that I welcome. Do you think you can attempt a reductio on PoSR (without meaninglessly just "opining" the absurdity)?or its opposite is absurd — Samuel Lacrampe
All humans are capable of reasoning about conflicting information without concluding that 2=5.Your argument is valid IF paraconsistent logic is true, that is, we observe that some objects — Samuel Lacrampe
If it's your position that you can prove self evident things, and it's your position that PoSR is self evident, then why all the fuss? Just prove PoSR, like I asked you to several posts before.It is indeed my position — Samuel Lacrampe
Because there's no inconsistency in a model including it. And since this is about reality, the most accurate authority of what reality is like is... reality itself. Instead of telling God what to do, you should just ask him what he's doing. So far, in the randomness camp, the ball could land either way... maybe it's MWI-like, maybe it's CI-with-BR-like.Why do you claim random mechanics is possible? — Samuel Lacrampe
If inquiring about what is true is equivalent to appealing to the PoSR, then you should be able to drop the PoSR postulate and replace it with a simple inquiry about what is true. So, if you're serious, do that... and derive that wavefunction collapse is unreal.Do you not see yourself appealing to the PoSR every time we enquire about what is true? — Samuel Lacrampe
No; and you would know that if you knew what necessary and sufficient means (i.e., you're bluffing again). But, okay, let's do this. A is sufficient for B means that if you have A, you definitely have B. A is necessary for B means that in order to have B, you have to have A. These are related but not the same; you can have mere reasons, necessary reasons, sufficient reasons, and necessary and sufficient reasons. The car swerving was a reason for the crash (but not necessary; I could have a crash by running into a telephone pole... and not sufficient; I could swerve to avoid such a car). For Pat to be a bride, it is necessary that Pat is female (but not sufficient; simply being a female doesn't make you a bride). If you ate a bowl of cereal this morning, that's sufficient to say that you had breakfast this morning (but not necessary; eating pancakes this morning would also be having breakfast this morning). For a computer to be Turing Complete, it is both necessary and sufficient that it be capable of simulating a Turing machine (a computer that cannot simulate a Turing machine is never Turing Complete; a computer that can is always Turing Complete).Are you perhaps conflating the terms "sufficient" with "necessary"? Otherwise, what is the difference between the two terms for you? — Samuel Lacrampe
From the same link: "In informal speech, self-evident often merely means obvious, but the epistemological definition is more strict." And also "A logical argument for a self-evident conclusion would demonstrate only an ignorance of the purpose of persuasively arguing for the conclusion based on one or more premises that differ from it (see [...] begging the question)."Nice try, but the definition I use aligns well with the definition given by your source, and poorly with your linked to "common" definition. And your definition-by-literal definition doesn't seem to fit at all. — InPitzotl
It does not. We believe a claim was justified because we believe the argument was sound. One cannot say that a claim was justified even though the argument was not sound. Hopefully that helps with your Newton objection too.It invalidates this point: [...] — InPitzotl
Inadequate in this context means "no rational error"; that is, the argument cannot be refuted given the currently available set of evidence. Note that it could be refuted at a later date, once further evidence is available. This is what happened with Newton and Einstein. Note also that a flawless argument can still fail to convince some people; but that doesn't make the justification itself "inadequate".But that's superfluous, since all "adequate" means is enough to convince you. — InPitzotl
We are definitely not on the same page; because my point is that not being able to prove the LNC is part of what makes the LNC self-evident.how is committing three fallacies to argue that a thing is self-evident going to help in your goal to convince the LNC denier that he shouldn't deny the LNC? — InPitzotl
Begging the question: Showing that one cannot avoid begging the question to demonstrate self-evidence is not a fallacy.Begging the question, appeal to personal incredulity ("I see no better way to..."), appeal to popularity. — InPitzotl
That's the problem. Your counter-examples fail to deal with criteria (1) and (2) at the same time. Dealing with criteria (1) or (2) separately is ... insufficient. :wink:No, just dealing with question begging separately. The appeal to popularity doesn't help; miasma theory, phlogiston, vitalism, spontaneous generation, all were popularly believed. — InPitzotl
You seem to fail to realize that a reductio ad absurdum is effective only when most of the population believes the alternative claim is absurd. In other words, reductio ad absurdum and appeal to popularity are both sides of the same coin.But reductio ad absurdum? That can actually be a valid argumentation technique. — InPitzotl
Sure thing; although note that it is not much different than my first attempt.Do you think you can attempt a reductio on PoSR (without meaninglessly just "opining" the absurdity)? — InPitzotl
If that's all you mean by paraconsistent logic, then it does not conflict with classical logic, and so we are done with this topic I suppose.All humans are capable of reasoning about conflicting information without concluding that 2=5. — InPitzotl
Correction: I can prove claims to be self-evident, not self-evident claims to be true. By definition, self-evident claims cannot be proven.you can prove self evident things — InPitzotl
What kind of model do you speak of? A computer model? But generating truly random numbers from computers is not possible. A model in your mind? But none of your thoughts are random or uncaused. There is a difference between the perception of randomness (ie we lack information to predict an effect) and real randomness.Because there's no inconsistency in a model including it. — InPitzotl
Can you point to, or write, a philosophical paper that adequately justifies the belief that wavefunction collapse is unreal? — InPitzotl
Are you saying that the wavefunction thing and the PoSR are incompatible? If so, I would just say that the wavefunction may be real, but that it has a cause, even if that cause may not be observable.So, if you're serious, do that... and derive that wavefunction collapse is unreal. — InPitzotl
I agree with you on the definitions of sufficient and necessary in logic. But I see 2 errors. First, as per the original link you sent, "This article is about the formal terminology in logic. For causal meanings of the terms, see Causality." and free will is about causality, not identity (logic). Second, if we must stretch the example to speak about cause and effect, then what causes you to eat cereals is the intent to have breakfast. So "intending to have breakfast" is the cause, and "eating cereals" is the effect. And like you said, the cause can also have the effect of "eating pancakes". So the PoSR does not remove the possibility of many options.If you ate a bowl of cereal this morning, that's sufficient to say that you had breakfast this morning (but not necessary; eating pancakes this morning would also be having breakfast this morning) — InPitzotl
Sure, that's the "common" one... "it's obvious". But also, in the common one, it simply says the epistemological definition is more strict. So my definition was: "Self evident means something that does not need to be demonstrated.". And the "philosophical" one, from the link: "a self-evident proposition is a proposition that is known to be true by understanding its meaning without proof". And your definition-from-literal:From the same link: — Samuel Lacrampe
You're quibbling over some interpreted "strictness" of my definition, but mine still aligns with the philosophical one, and yours is still nowhere close.The term "self-evident" literally means "evidenced by itself". You don't see it? — Samuel Lacrampe
...okay, but that doesn't quite fit, because far from being ignorant of begging the question, you're literally embracing it. Your source seems to treat it as a bad thing. Also, you have this theory that debates lead to truth; so there must be something you can debate me with that would convince me.And also — Samuel Lacrampe
No, because we believe Newtonian mechanics was justified pre-Einstein, yet we don't believe it's sound. And belief that an argument is sound is not the same thing as an argument being sound.We believe a claim was justified because we believe the argument was sound — Samuel Lacrampe
IEP did.One cannot say that a claim was justified even though the argument was not sound.
Okay, let's go with that one then. In the current knowledge base of physics, best I understand, randomness cannot be refuted given the currently available set of evidence, nor can determinism be refuted given the currently available set of evidence. So neither conclusion is a rational error.Inadequate in this context means "no rational error"; that is, the argument cannot be refuted given the currently available set of evidence. — Samuel Lacrampe
And that's ridiculous. Not being able to prove massless cows are eating massless grass in the center of the sun doesn't make it self evident. You can't prove something is self evident by begging the question. And you can't prove it by begging the question and appealing to popularity.We are definitely not on the same page; because my point is that not being able to prove the LNC is part of what makes the LNC self-evident. — Samuel Lacrampe
I agree. But using the fact that something begs the question to "prove" that something is self evident is a fallacy.Begging the question: Showing that one cannot avoid begging the question to demonstrate self-evidence is not a fallacy. — Samuel Lacrampe
No, that's not the problem. The problem is that you're using logical fallacies to justify that claims are self evident, not that I'm not using enough of them.That's the problem. — Samuel Lacrampe
The problem isn't that I "fail to realize" this; the problem is that it's flat out wrong and you're just making it up. Since when did reductio have to do with popular opinion? Wiki gives this example of a reductio:You seem to fail to realize that a reductio ad absurdum is effective only when — Samuel Lacrampe
...how is this even related to people's beliefs in smallest positive rationals?There is no smallest positive rational number because, if there were, then it could be divided by two to get a smaller one.
As for (1), you're confusing justification with proof; I don't hold PoSR to be self evident; and you're trying to prove PoSR anyway. As for (2), nonsense; denial of PoSR does not require invalidating the demand to justify all claims. In fact, Quantum Indeterminism itself is even a thing because it can be justified. Real experiments show QM works. Born Inequalities provide a way to show the difference between application of BR according to QM and hidden variables. Real experiments bear BI out. Add some aesthetics, such as presumptions like that classical physics is real (by presuming that QM is just a calculation trick for example), and you get justified randomness.(1) it cannot be evidenced by anything else ... (2) Its contradictory (ie "not everything must have a reason or a cause") is absurd, because it invalidates the demand to justify any claims ever. E.g. the soul exists. Much shorter OP. — Samuel Lacrampe
A conceptual model; a Copenhagen Interpretation of QM with WFC realism. It's conceivably possible WFC is real.What kind of model do you speak of? — Samuel Lacrampe
How do you know? They could be. But even if they aren't, that's irrelevant. None of my thoughts grow leaves either, but I can think of trees. And even if my thoughts are all caused and non-random, I can think of the word "random". There are thoughts like Bell Inequalities, and thoughts like "let's find out"; as agents we can interact with the world and, say, perform experiments confirming Bell's Theorem. Ask God what he's doing.But none of your thoughts are random or uncaused. — Samuel Lacrampe
And?There is a difference between the perception of randomness (ie we lack information to predict an effect) and real randomness. — Samuel Lacrampe
Yes; "real" WFC and PoSR are incompatible ("real" meaning a WFC theory that treats it as real rather than merely MWI or QD or something).Are you saying that the wavefunction thing and the PoSR are incompatible? — Samuel Lacrampe
Ironic... you're right on both fronts, but in being right you demonstrate you have no idea what you're talking about. Lucky you for being right. Wavefunction realism is what MWI posits. The wavefunction evolves according to the Schrodinger Equation, and that's completely deterministic. It's also, coincidentally, not observable. But that's not where quantum indeterminism comes in. Quantum indeterminism comes in when the Born Rule applies; the Born Rule is entirely stochastic in nature. The Born Rule results in a wave function collapse (WFC). Wave function collapses take the quantum wavefunction and bring them into a classical result, when it's observed. WFC realism would posit that the collapse is real... that pieces of the wavefunction actually disappear into classical measurements. That implies quantum indeterminacy, and that is incompatible with PoSR.If so, I would just say that the wavefunction may be real, but that it has a cause, even if that cause may not be observable. — Samuel Lacrampe
Funny, because you didn't show any error in what you typed. You just had two comments:But I see 2 errors. — Samuel Lacrampe
...so go to that link."This article is about the formal terminology in logic. For causal meanings of the terms, see Causality." — Samuel Lacrampe
...well, that link phrased it thusly:Just because A is sufficient to cause B, it does not follow that A will necessarily cause B every time. — Samuel Lacrampe
If x is a sufficient cause of y, then the presence of x necessarily implies the subsequent occurrence of y. — Causality
Doesn't matter. PoSR states that everything has a sufficient reason. That includes "eating breakfast", but it also includes "eating cereal for breakfast". Ignoring the latter is simply cherry picking; the rule, if it applies, applies to everything (because that's what the rule says it applies to). Besides, if we can just clump alternatives and ignore the specifics and that "counts", then PoSR doesn't rule out randomness, because Banno's photon went through "a slit".if we must stretch the example to speak about cause and effect, then what causes you to eat cereals is the intent to have breakfast. — Samuel Lacrampe
But we're playing the debate game... isn't that what you wanted? After all, isn't that how truth is demonstrated... by spinning wheels trying to convince people your points don't need justified because by committing the right two fallacies you prove it's self evident?We'll call it a draw on the topics we drop haha. — Samuel Lacrampe
Maybe there's a deeper principle like this, where everything happens for a reason. — InPitzotl
But if a claim does not need to but can be demonstrated, then it means it could be demonstrated without begging the question, which the statement in the wiki disallows. Or leaving the wiki aside, we agreed we could also call a self-evident claim a "first principle". But we demonstrate a claim by appealing to a principle prior to that claim, which cannot exist for first principles, by definition.my definition was: "Self evident means something that does not need to be demonstrated." — InPitzotl
?? My point is the same as that of the wiki, namely that any attempt to demonstrate a self-evident claim to be true would be committing the fallacy of begging the question.that doesn't quite fit, because far from being ignorant of begging the question, you're literally embracing it. — InPitzotl
It was justified. It no longer is. Similarly, we believed it was sound, we no longer do.No, because we believe Newtonian mechanics was justified pre-Einstein, yet we don't believe it's sound. And belief that an argument is sound is not the same thing as an argument being sound. — InPitzotl
But randomness and determinism are contradictory, aren't they? If so, then how can the currently available set of data lead to two contradictory conclusions?In the current knowledge base of physics, best I understand, randomness cannot be refuted given the currently available set of evidence, nor can determinism be refuted given the currently available set of evidence. So neither conclusion is a rational error. — InPitzotl
Why do you say the "massless cows" claim cannot be demonstrated true or false without begging the question? And why do you say the claim is popularly believed?Not being able to prove massless cows are eating massless grass in the center of the sun doesn't make it self evident. You can't prove something is self evident by begging the question. And you can't prove it by begging the question and appealing to popularity. — InPitzotl
Why is that a fallacy? Also I suspect you do not understand the statement in the Wiki link, because it supports my claim.But using the fact that something begs the question to "prove" that something is self evident is a fallacy. — InPitzotl
The Wiki states the reductio ad absurdum "attempts to establish a claim by showing that the opposite scenario would lead to absurdity or contradiction." Your example is an example of contradiction, not absurdity. Admittedly, I did not know we would also call it "reductio as absurdum" in that case. Anyways, back to the self-evident criteria, I mean it to say "absurd", not "contradiction". And "absurd" means "away from common sense".There is no smallest positive rational number because, if there were, then it could be divided by two to get a smaller one.
A proof is a justification that gives certainty. And I honestly don't understand the rest of your claim.(1), you're confusing justification with proof; I don't hold PoSR to be self evident; and you're trying to prove PoSR anyway. — InPitzotl
You seem to appeal to the PoSR to support these theories, and then conclude that the PoSR is false. Is this not like sawing off the branch you are sitting on? I offer a better explanation that preserves the PoSR all the way through: these theories don't exclude the possibility of a non-physical cause.Quantum Indeterminism itself is even a thing because it can be justified. — InPitzotl
We can imagine the literal word "random" made of letters, we cannot imagine randomness; because we have never perceived randomness, and we cannot imagine something we have not perceived, inasmuch as a blind man born blind cannot imagine a colour. At best, we can imagine "unpredictability". Similarly, it is useful to talk about "infinity" in math, but we cannot imagine it.I can think of the word "random" — InPitzotl
Interesting. I did not know that was what "sufficient cause" means. Alright.If x is a sufficient cause of y, then the presence of x necessarily implies the subsequent occurrence of y. — Causality
You keep treating demonstrate/justify and logical proof as the same thing. All three are different things. You demonstrate something by just doing a thing and showing that a principle is working, for that one event. You justify something by giving a good reason to believe it. You prove something logically by applying logical axioms and/or theorems.But if a claim does not need to but can be demonstrated, then it means it could be demonstrated without begging the question, which the statement in the wiki disallows. — Samuel Lacrampe
We're not agreeing on what is self evident. But you're trying to prove something is self evident, and at the same time, trying to say that you cannot prove it.Or leaving the wiki aside, we agreed we could also call a self-evident claim a "first principle". But we demonstrate a claim by appealing to a principle prior to that claim, which cannot exist for first principles, by definition. — Samuel Lacrampe
No it's not; you've confused yourself into thinking it's the same. The wiki says exactly this:My point is the same as that of the wiki — Samuel Lacrampe
...what you're not grasping is that this is a direct criticism of your attempts to logically argue for a self evident conclusion. This wiki is saying that you by doing so are demonstrating an ignorance of the purpose of persuasively arguing for the conclusion... that you're begging the question. That's supposed to be a bad thing, but you're doing it.A logical argument for a self-evident conclusion would demonstrate only an ignorance of the purpose of persuasively arguing for the conclusion based on one or more premises that differ from it (see ignoratio elenchi and begging the question).
It was justified but it was never sound. Relativity didn't become true when Einstein proposed it; to the degree that it's "truer" than Newton, it was "truer" dating back to the Big Bang singularity.It was justified. It no longer is. — Samuel Lacrampe
No, you suspect I don't understand the Wiki link because you do not understand it. See the quote above? Who is offering a logical argument that PoSR is self evident? That's not me, that's you. So who is being demonstrated ignorant of the purpose of persuasively arguing that position? If anyone that would be you, not me; I'm the attempted persuadee, you're the persuader. I'm the one doubting the PoSR is self evident. And who is begging the question by proposing that logical argument? Not me; that's you. I'm unconvinced PoSR is self evident, so I'm asking, not for a logical argument, but for a justification. Because... whose opinion is it that debates lead to truth? Not mine; that's yours.Why is that a fallacy? Also I suspect you do not understand the statement in the Wiki link, because it supports my claim. — Samuel Lacrampe
...according to Einstein (apocryphally but believably), common sense is the set of prejudices learned by the age of 18.And "absurd" means "away from common sense". — Samuel Lacrampe
How?You seem to appeal to the PoSR to support these theories, — Samuel Lacrampe
Wrong; I conclude PoSR isn't necessarily true. It's just a simple modal logic exercise. Maybe instead of bluffing you should read up on modal logic.and then conclude that the PoSR is false.
It's trivially false that I cannot imagine something I don't perceive. I can imagine that there's a kidney underneath my skin somewhere; I can imagine the pipe running to my property delivering water. I can imagine uncomputable numbers, incompressible numbers, Godel numbers, and TM's that UTM's cannot decide are halting or not. I can imagine dependence and independence. You're fishing.We can imagine the literal word "random" made of letters, — Samuel Lacrampe
Unless you're prepared to argue that there are a finite number of counting numbers because PoSR, I don't think you want to go there.Similarly, it is useful to talk about "infinity" in math, but we cannot imagine it. — Samuel Lacrampe
Sufficient has meant that since before you started your post. And I've been telling you what it means. I linked to an article even; you obviously didn't read it. Not until I spoon fed it did you agree. So what made you think you were qualified to lecture me on what sufficient means if you had no idea?Interesting. I did not know that was what "sufficient cause" means. Alright. — Samuel Lacrampe
Not in the context of the PoSR; which is what matters for this post. To confirm, in the statement about the PoSR "For every event E, if E occurs, then there is a sufficient explanation for why E occurs", "sufficient" means that the effect cannot be greater than its causes. And it is in that sense that I use the term "sufficient" for this post.Sufficient has meant that since before you started your post. — InPitzotl
I'll try one more time, but I'm running out of ways to explain the same thing. To demonstrate that a claim is self-evident is not the same as to demonstrate that a self-evident claim is true. The latter is a fallacy; the former is not. My aim is to show that the PoSR is self-evident, not that it is necessarily true.I'm the one doubing the PoSR is self evident. — InPitzotl
Sounds like we are in agreement here. Let's close this topic.It was justified but it was never sound.[...] — InPitzotl
By saying that "Quantum Indeterminism itself is even a thing because it can be justified", it is appealing to the PoSR in the form of "For every proposition P, if P is true, then there is a sufficient explanation for why P is true." So QI theory is believed to be true because there is a sufficient explanation in support of it. Likewise, if there was not a sufficient explanation in support of it, then QI would not be believed to be true.How [am I appealing to the PoSR]? — InPitzotl
That's not quite what I meant, but that's okay because I have changed my mind on this. We can after all imagine an event without imagining a cause for that event. That's fine; it just means that the PoSR is not derived from logical necessity (which is what we'd expect from a self-evident principle).It's trivially false that I cannot imagine something I don't perceive. — InPitzotl
It is indeed not "necessarily true" in the sense that it is not derived from logical necessity, as per above, but I clam it is nevertheless true for all cases, similar to how logic cannot itself be derived from logical necessity, and yet is believed to be true for all cases.Wrong; I conclude PoSR isn't necessarily true. [...] — InPitzotl
Thomas Aquinas was already talking about this back then (but I cannot find the source of this anymore). — Samuel Lacrampe
That sounds like special pleading to me. But, okay.Not in the context of the PoSR — Samuel Lacrampe
And what does greater mean? Surely snowflakes can cause avalanches, and hurricanes can result from a butterfly flapping its wings. Is a rock greater than a stick? Is elasticity greater than magnetism? Are you just saying that if something requires x amount of energy then you need at least x amount of energy? Greater has to actually mean something you can use if you're going to define PoSR this way, and if it does, I'd like to know what that meaning is."sufficient" means that the effect cannot be greater than its causes. — Samuel Lacrampe
Okay, I'll attack this differently too... let's start here. Do you mean that PoSR is "obvious" (the common definition)? Because it's not so obvious to me. Or do you mean that PoSR "is known to be true without justification"? Because that would entail that I know it to be true, and I can find reasonable doubt of it being true (WFC realism). Because I can reasonably doubt it, you have to justify it to me. That's what this stuff really means. And what you're really trying to do is futile on top of futile... you're trying to prove to me that you don't have to justify PoSR to me.My aim is to show that the PoSR is self-evident, not that it is necessarily true. — Samuel Lacrampe
It's not even related to the that claim; it's appealing only to the fact that a belief is justified if there's justification for it, which is kind of tautological. In fact, "For every proposition P, if P is true, then there is a sufficient explanation for why P is true" is not even true! If your version of PoSR entails that it is, then I straight out disbelieve it; Godel's First Incompleteness Theorem's much better justified.By saying that "Quantum Indeterminism itself is even a thing because it can be justified", it is appealing to the PoSR in the form of "For every proposition P, if P is true, then there is a sufficient explanation for why P is true." — Samuel Lacrampe
Greater in terms of "causal power" or "ability". This is still quite generic, so I'll give examples.And what does greater mean? Surely snowflakes can cause avalanches, and hurricanes can result from a butterfly flapping its wings. Is a rock greater than a stick? Is elasticity greater than magnetism? Are you just saying that if something requires x amount of energy then you need at least x amount of energy? — InPitzotl
I assume "randomness" here means that sometimes we observe event A and sometimes event B, with no apparent causes to explain that change. So if every change requires a sufficient cause, this type of randomness indeed cannot exist.that has to be the thing you use to rule out Born Rule application of wave function collapse, because that's precisely what you're ruling out when you rule out the randomness Banno was talking about. — InPitzotl
If the possible worlds only retain logic, then indeed randomness is possible in other worlds; but if they retain both logic and causality, then randomness is not possible. I'd say both should be retained because possible worlds are thought experiments, and both LNC and PoSR are laws of thought (as further explained below).even if you ruled this out, the theory Banno described would do perfectly well as a physical theory... it just wouldn't apply to our world — InPitzotl
This one. The PoSR cannot be founded on anything else because nothing is below a first principle; but we can explain how it came about: The purpose of reason is to find truth, and we observe that when we reason about a topic, we always demand an explanation that is sufficient to defend the claim, and we reject the claim when the explanation is found to be insufficient (ie failing to fulfill the burden of proof). Thus inductively, the PoSR is the generalization of this observation. I'm pretty sure the LNC came about in a similar way, for it cannot be demonstrated either. Leibniz says the LNC and the PoSR are the two pillars of our reasoning about reality, where the former is for identity, and the latter for causality.do you mean that PoSR "is known to be true without justification"? — InPitzotl
The scientific method is based on reason, which uses both the LNC and the PoSR. E.g. "Assume a claim is false until given a sufficient reason to be true", or Occam's Razor which is "pick the simplest hypothesis that explains all the data", etc. So a scientific claim which refutes either the LNC or the PoSR would be sawing off the branch it is sitting on. That said, the WFC may be compatible with the PoSR if we posit non-observable causes. I just don't know enough about that theory.Well, what about my reasonable doubt... the possibility that WFC is real? — InPitzotl
I'm not sure what your point is in this last paragraph.It's not even related to the that claim [...] — InPitzotl
Within the domain of math, per your definition, I read "sufficient reason" as being equivalent to proof.I'm not sure what your point is in this last paragraph. — Samuel Lacrampe
That doesn't sound generic to me, though it sounds a bit trivial. If we agree that A causes B, we could say that A has "resulting in B" as its causal power, which I see as simply a fancy way of saying that A can cause B. I don't get where "greater" comes in though. Wavefunction collapse causes the photon to go left. Okay, and?Greater in terms of "causal power" or "ability". — Samuel Lacrampe
That implies that the total amount of energy in the universe can remain the same, or decrease, but cannot increase. But that conflicts with the fact that the total amount of energy in the universe is increasing (due to dark energy). So, what gives?Indeed if talking about energy events, then the energy from the effect cannot be greater than the energy from the causes — Samuel Lacrampe
No, I mean that state Φ sometimes evolves into state A and sometimes evolves into state B, and we can demonstrate that there exists no hidden variable that can explain the evolution of state A from state Φ as opposed to state B from state Φ. Being able to demonstrate that there are no HVT's is strikingly different than merely not seeing an apparent sufficient cause. Quantum indeterminacy is not based on pattern matching events; it's based on an evidence supported no-go theorem (Bell's Theorem).I assume "randomness" here means that sometimes we observe event A and sometimes event B, with no apparent causes to explain that change. — Samuel Lacrampe
That does not imply∀P, P ⇒∃O:O⊢P; all it implies is that we don't commit to P until we find an O such that O⊢P (with a much weaker sense of ⊢... an outright falsifiable sense... since we're dealing with induction most of the time).The purpose of reason is to find truth, and we observe that when we reason about a topic, we always demand an explanation that is sufficient to defend the claim, and we reject the claim when the explanation is found to be insufficient (ie failing to fulfill the burden of proof). — Samuel Lacrampe
Reason doesn't rely on PoSR. You're making that up. There is no "∀P, P ⇒∃O:O⊢P" in "O⊢P".The scientific method is based on reason, which uses both the LNC and the PoSR. — Samuel Lacrampe
First, bear with me when using symbolic logic, because I am not familiar with these.In terms of math, when you say "X can be justified" appeals to your phrasing of the PoSR, given "proof"=sufficient reason, then you're literally saying that "O⊢P" appeals to "∀P, P ⇒∃O:O⊢P", which is ridiculous on the face of it. — InPitzotl
"Greater" may not always apply, as per your example. But it does in some cases: If a shelf can support a 10 kg weight but can also support more, then the being that is the cause has greater power (supporting power) than the effect (the supporting of the 10 kg weight).I don't get where "greater" comes in though. Wavefunction collapse causes the photon to go left. Okay, and? — InPitzotl
Dark Energy... sounds ominous. I don't know what that is, but doesn't it conflict with the first law of thermodynamics, that the total energy of an isolated system is constant; energy can be transformed from one form to another but can be neither created nor destroyed?But that conflicts with the fact that the total amount of energy in the universe is increasing (due to dark energy). — InPitzotl
The domain of the empirical sciences (what we refer to as science for short) is limited to the empirical. But reality is not necessarily limited to the empirical. So while science may demonstrate there are no additional empirical causes, it cannot make claims about possible non-empirical causes.Being able to demonstrate that there are no HVT's is strikingly different than merely not seeing an apparent sufficient cause. — InPitzotl
But we don't commit to P, precisely because there is an insufficient explanation to claim that P is true.That does not imply∀P, P ⇒∃O:O⊢P; all it implies is that we don't commit to P until we find an O such that O⊢P (with a much weaker sense of ⊢... an outright falsifiable sense... since we're dealing with induction most of the time). — InPitzotl
It sure does. The three types of reasoning are deductive, inductive, and abductive. Abductive is "inference to the best explanation"; and this implies a sufficient explanation.Reason doesn't rely on PoSR. — InPitzotl
Not in the realm of mathematics; proof is generally the level we're looking for. What weaker sufficient reason would you apply to mathematics?Now the term "proof" is too strict — Samuel Lacrampe
Could you explain that a bit more?Of course, first principles cannot be proven to be true, by definition, but sufficient reasons nevertheless are given to make them reasonable, such as induction. — Samuel Lacrampe
But this is your burden... to show randomness is impossible. Quantum Indeterminacy comes from application of Born Rule, which is the rule that you apply when you get classical states from the wavefunction collapsing. If greater doesn't apply here, then there's no argument against randomness in this."Greater" may not always apply, as per your example. — Samuel Lacrampe
Yes. This is an analog to Newton's Laws we were discussing earlier. Conservation of energy is a really great law, and it's "almost" true; it is, in fact, so close to being true that we may as well just say that it is. But we can derive conservation of energy from more fundamental laws; in accordance with Noether's Theorem, conservation of energy is a result of time translation symmetry. Dark energy introduces a time translation asymmetry, and dominates the universe at cosmic scales.doesn't it conflict with the first law of thermodynamics, that the total energy of an isolated system is constant — Samuel Lacrampe
This paragraph is meaningless to me. Based on my understanding of what the word "empirical" means, it's a bunch of babble, and straight out false... it's tantamount to saying that there's no such thing as a no-go theorem in science, which is quite silly given Bell's Theorem is such a thing. But based on what I understand the word "empirical" to mean, some of these phrases are outright nonsense; for example, what is this supposed to mean?: "may demonstrate there are no additional empirical causes"The domain of the empirical sciences (what we refer to as science for short) is limited to the empirical. But reality is not necessarily limited to the empirical. So while science may demonstrate there are no additional empirical causes, it cannot make claims about possible non-empirical causes. — Samuel Lacrampe
What are you talking about? P=an english speaker is engaging me in a conversation. O=this thread. O⊢P. Are you failing to abstract? You're talking about a principle that supposedly applies to all true things.But we don't commit to P, precisely because there is an insufficient explanation to claim that P is true. — Samuel Lacrampe
Probability. Reasonableness is equivalent to probability in mathematics without being quantitative. Note however, that the PoSR applies first and foremost to causality, and secondarily to knowledge, as an extension.Not in the realm of mathematics; proof is generally the level we're looking for. What weaker sufficient reason would you apply to mathematics? — InPitzotl
Take the LNC as a first principle for example. It cannot be proven to be true, for a logical proof presupposes the LNC. But through induction, by observing that there exist no contradictory facts, and that we cannot even imagine contradictory images, then it is reasonable to believe the LNC to be true, both as an epistemic and a metaphysical principle.Could you explain that a bit more? — InPitzotl
There is a misunderstanding somewhere here. I thought you were just asking if along with being greater, the cause can sometimes just be equal, and I meant to say that it can; that it just cannot be less. If that's not what you meant, then what was your original objection?But this is your burden... to show randomness is impossible. Quantum Indeterminacy comes from application of Born Rule, which is the rule that you apply when you get classical states from the wavefunction collapsing. If greater doesn't apply here, then there's no argument against randomness in this. — InPitzotl
I wish laws would stop being broken. :shade:Dark energy introduces a time translation asymmetry, and dominates the universe at cosmic scales. — InPitzotl
That science may be able to show in some cases that it has accounted for all the causes that science can account for: observable, detectable causes. E.g. there may exist things which are typically judged to be non-physical such as the soul, free will, and objective values. As non-physical things, they might fall outside the realm of empirical sciences, and are part of the realm of philosophy (which nowadays means "non-empirical or rational sciences"). As possibly real things, they would be part of the causal chain of events alongside with physical things.what is this supposed to mean?: "may demonstrate there are no additional empirical causes" — InPitzotl
So this translates to "this thread is a proof that an engligh speaker is engaging me in a conversation". So far so good; no conflict with the PoSR that I see. But then what is your point?P=an english speaker is engaging me in a conversation. O=this thread. O⊢P. — InPitzotl
You seem to be losing the ability to understand what you're quoting. Mathematical conjectures are not judged based on the probability that they are true; they are judged based on whether they can be proven or disproven.Probability. Reasonableness is equivalent to probability in mathematics without being quantitative. Note however, that the PoSR applies first and foremost to causality, and secondarily to knowledge, as an extension. — Samuel Lacrampe
But if you're appealing to induction, then induction is in play; in that case, we can appeal to quantum indeterminacy as a reason to doubt PoSR.But through induction, by observing that there exist no contradictory facts, and that we cannot even imagine contradictory images, then it is reasonable to believe the LNC to be true, both as an epistemic and a metaphysical principle. — Samuel Lacrampe
Indeed there is. You said this, here:There is a misunderstanding somewhere here. — Samuel Lacrampe
...and I got two concrete examples from you; one was support-ability of a beam by weight... the other was conservation of energy. The weight thing sounds fine, but hardly universal; I can think of several other principles where "lesser" amounts of some total are required for some thing, but PoSR must apply to all things not just certain classes of things, else there's no such rule. The conservation of energy thing plain fails, but:To confirm, in the statement about the PoSR "For every event E, if E occurs, then there is a sufficient explanation for why E occurs", "sufficient" means that the effect cannot be greater than its causes. — Samuel Lacrampe
...and that seems to be a curious exception. You gave this as an example of PoSR applying; turns out it flunks. But now you're backtracking. I'll allow this, but, there's a cost. So maybe PoSR is fine with energy increasing after all; you can pin that on time translation asymmetry. But if you can be wrong about this because energy can indeed increase due to time translation asymmetry, then how can we be sure you cannot be wrong about quantum indeterminacy because events can indeed be stochastic due to wavefunction collapse, in the same manner in which you allow indeterministic free will because events can be caused by original causes who are free agents?This should still be okay with the PoSR. — Samuel Lacrampe
The word "empirical" refers to something you actually observe though; so phrases like ruling out empirical causes literally mean that you're ruling out causes that you observe, which is kind of nonsensical. In like fashion your previous rant about empirical science being science and what not is a bunch of meaningless babble that should just be ignored. As for the above statement, that's a bit more meaningful, but it shows lack of imagination and a complete ignorance of what a no-go theorem is. Bell's Theorem does not require the causes be observable or detectable; it merely requires that there be some sort of fact of the matter of the classical system that leads to the result.That science may be able to show in some cases that it has accounted for all the causes that science can account for: observable, detectable causes. — Samuel Lacrampe
And now we're full circle? The photon goes left because it has a soul, free will, and objective values?E.g. there may exist things which are typically judged to be non-physical such as the soul, free will, and objective values. — Samuel Lacrampe
You have a talent for not following the discussion. You posited that by using a justification for a belief (O⊢P) that I'm appealing to PoSR (∀P, P ⇒∃O:O⊢P). I'm saying that just using a justification for a belief (O⊢P) does not require an appeal to PoSR (∀P, P ⇒∃O:O⊢P). Think of ⊢ mathematically as meaning proof; outside of math, as simply being a metaphor for justifies. But you're still trying to cargo cult some sort of ridiculous foundational dependency of (O⊢P) to (∀P, P ⇒∃O:O⊢P).So this translates to "this thread is a proof that an engligh speaker is engaging me in a conversation". So far so good; no conflict with the PoSR that I see. But then what is your point? — Samuel Lacrampe
Pure mathematics is in the domain of identity, not causality. E.g. 2+2=4 means that 2+2 is identical to 4, not that 2+2 causes 4. PoSR is in the domain of causality. Regardless, why bring up maths?Mathematical conjectures are not judged based on the probability that they are true; they are judged based on whether they can be proven or disproven. — InPitzotl
But if you're appealing to induction, then induction is in play; in that case, we can appeal to quantum indeterminacy as a reason to doubt PoSR. — InPitzotl
As previously stated, the PoSR is part of reasoning (at least abductive) which is part of the scientific method which is used for that QI theory. You cannot remove the PoSR from scientific topics. It would be like showing through science that some facts about reality are contradictory, thereby concluding that the LNC sometimes fails, and this would be acceptable because the LNC was also obtained through induction. We judge scientific theories based on their agreement with principles of reason, and not the opposite way around.So, come on, give me something meaningful enough to do the job you want to do; something that doesn't sound like special pleading. — InPitzotl
You misunderstand. My position is in defence of the PoSR, not the laws of thermodynamics. So this time-translation-asymmetry thing is what explains an exception in the law of thermodynamics. Great. It's a blow for the laws of thermo, but it perfectly agrees with the PoSR. Your example would only go against the PoSR if it wasn't explained by something like the time-translation-asymmetry.The conservation of energy thing plain fails — InPitzotl
No. PoSR states that all changes have a sufficient cause. Randomness means that nothing causes the change between scenarios 1 and 2, where in scenario 1, Cause A results in Effect B, and in scenario 2, Cause A results in Effect C. Randomness fails the PoSR.PoSR by this theory is meaningless, and lacks the ability to rule out randomness. — InPitzotl
Let's get one thing out of the way. The whole objection about those quantum theories doesn't actually harm the original argument in the OP. All I need to do is to revamp it a bit as per below. This is to clarify that my position on the PoSR is not driven by my position on the soul.the whole point of PoSR was to rule out randomness so you could use this proof of souls. — InPitzotl
It means that science cannot rule out non-empirical causes.The word "empirical" refers to something you actually observe though; so phrases like ruling out empirical causes literally mean that you're ruling out causes that you observe, which is kind of nonsensical. — InPitzotl
I would say another non-physical cause; but yes. But now are you claiming that you know for a fact that non-physical things don't exist? Because it seems this would be needed to invalidate the PoSR.And now we're full circle? The photon goes left because it has a soul, free will, and objective values? — InPitzotl
Can you find an example of a claim that is widely accepted as true and also has no justification for it? If not, then it is an indication of the universal appeal to the PoSR.I'm saying that just using a justification for a belief (O⊢P) does not require an appeal to PoSR (∀P, P ⇒∃O:O⊢P). — InPitzotl
Mathematics includes many fields, not just equations with equals signs on them. But provability is not just an analog of justification, but an example of it. And it was justification that you claimed appeals to PoSR.Pure mathematics is in the domain of identity, not causality. — Samuel Lacrampe
Who is this "we"? The scientific community has no consensus on whether quantum indeterminacy is a thing or not. So if there's a PoSR that science relies on that does rule this out, somebody forgot to inform scientists about it.We judge scientific theories based on their agreement with principles of reason, and not the opposite way around. — Samuel Lacrampe
Quantum indeterminism is explained by something like wavefunction collapse, backed by the Born Rule. Let me label this so you can follow:Your example would only go against the PoSR if it wasn't explained by something like the time-translation-asymmetry. — Samuel Lacrampe
(a) Can you find an example of a claim that is widely accepted as true and also has no justification for it? — Samuel Lacrampe
(b) first off is more nonsense. Randomness has nothing to do with changing a scenario to a different one. Quantum mechanics (per ordinary CI) involves a state A (namely, the state of a wavefunction) sometimes leading to Effect B (a particular classical state) and sometimes to Effect C (a distinct classical state). Quantum indeterminacy treats this collapse of quantum states to classical ones as real. Bell's Theorem rules out that there's a classical fact of the matter that leads to Effect B as opposed to Effect C in conditions where the former happens, by demonstrating that if there were, you would wind up with constraints in probability distinct from the Born Rule probabilities, and showing by experiment that you actually get the BR ones. So QI in this sense is justified by induction and reasoning (which is not the condition of a, but still conflicts with b). You're trying to rule out that reasoning, by saying that by reasoning we appeal to some foundational principle of reason that rules it out. But there is no such thing in the reasoning that leads to QI. The entire argument is nothing but sophistry. If there were any meat to it, and any actual scientific consensus (such as the one you pretend to appeal to), then the scientific community would rule out quantum indeterminacy based on such principles.(b) Randomness means that nothing causes the change between scenarios 1 and 2, where in scenario 1, Cause A results in Effect B, and in scenario 2, Cause A results in Effect C. Randomness fails the PoSR. — Samuel Lacrampe
Again, that's nonsensical. I drop a rubber ball in a dark room. I hear it bounce off of the floor, then bounce again, and again. The time distance between each bounce is faster. I can infer that the ball is falling, bouncing, and going back up; each time, it's losing energy to heat and sound, causing it not to return to the original height, causing it to fall back down faster. I don't have a thermometer, and I don't see the ball. The ball bouncing in this case is theoretical, as is the explanation of what I hear; it's not empirical because it's not observed. The causes I attribute are theoretical and not empirical. There is a non-empirical cause inferred by the evidence supported theory, and that is an application of science. We can rule out the non-empirical cause of the sounds we hear that energy is just being lost, based on appeal to the scientific theory. This is proper use of the term "empirical". Your usage is kind of an abuse.It means that science cannot rule out non-empirical causes. — Samuel Lacrampe
You're lost again (and just flirting with the fallacy fallacy). Bell's Theorem is a no-go theorem that rules out HVT's. You replied to this by some nonsense about how science cannot rule out "non-empirical causes" like it actually does in the simple example above. In your response you give "examples" of "non-empirical causes" like souls, free will, an objective values. So naturally, in context (were you not lost), you would be proposing that Bell's Theorem fails to rule out HVT's involving souls, free will, and objective values. But of course, you are indeed lost. Your fault, not mine; follow the threads back.But now are you claiming that you know for a fact that non-physical things don't exist? — Samuel Lacrampe
But that's the entire basis of my objection. If you stop trying to wring blood out of this stone, I have the right to revise my entire stance, up to and including having no particular objections. However, this particular rephrasing of your premises is a bit weak. You seem to be saying now that everything deterministic is physical, unless it's at quantum scales, in which case it gets to be physical and not be deterministic. That... seems a bit fuzzy. It's a strange, contextual sense of physical, which doesn't quite seem like that's enough to save your argument. Pardon me, but out of curiosity, why exactly do you need the soul to be non-physical in the first place? What's wrong with a physical soul?The whole objection about those quantum theories doesn't actually harm the original argument in the OP. — Samuel Lacrampe
Sure, provability is an example of justification; but not the only one. And one field of mathematics that is relevant to causality is statistics, which uses probability as a justification. In fact, most scientific hypotheses are validated with a probability (such as rejecting the null hypothesis), not a certainty.Mathematics includes many fields, not just equations with equals signs on them. But provability is not just an analog of justification, but an example of it. And it was justification that you claimed appeals to PoSR. — InPitzotl
The scientific community has no consensus on whether quantum indeterminacy is a thing or not. So if there's a PoSR that science relies on that does rule this out, somebody forgot to inform scientists about it. — InPitzotl
My understanding is that the reason why the QI theory is not universally accepted, and deemed incomplete by some, is precisely because the theory fails to satisfy our demand for a sufficient explanation. E.g. "God does not play dice", etc.If there were any meat to it, and any actual scientific consensus (such as the one you pretend to appeal to), then the scientific community would rule out quantum indeterminacy based on such principles. — InPitzotl
A requirement for empirical science is that the hypothesis brought forth must be empirically verifiable. Your hypothesis falls under this science because we can empirically verify it by turning on the light, or by using a night-vision camera, etc. On the other hand, if the hypothesis was not empirically verifiable, e.g. illusion caused by brain-in-a-vat, then it would not be considered scientific, but philosophical.I drop a rubber ball in a dark room. [...] — InPitzotl
Let's examine this line of reasoning some more. You are here making an inference to the best explanation, aka abduction, which brings forth the simplest hypothesis that sufficiently explains all the data. This is correct scientific reasoning founded on the PoSR. If on the other hand, we dropped the PoSR and allowed the possibility that nothing causes the phenomenon observed, then this "no cause" hypothesis would be the simplest and thus most reasonable one to begin with; which would be absurd.I can infer that the ball is falling, bouncing, and going back up; each time, it's losing energy to heat and sound, causing it not to return to the original height, causing it to fall back down faster. — InPitzotl
To clarify, I am not claiming we should believe that non-physical things exist until given a reason to believe otherwise. But likewise, we shouldn't believe they don't exist as default. And if we remain agnostic on non-physical things but allow the possibility for their existence, then the absence of a physical cause in an event is not an effective argument against the PoSR.and just flirting with the fallacy fallacy — InPitzotl
Based on what I've read, the HVT is in reference to local hidden variables, which implies entities with a location property. And all entities that have a location property are physical, because physical properties such as location don't apply to non-physical entities.Bell's Theorem is a no-go theorem that rules out HVT's. — InPitzotl
Traditionally, what is referred to as the "soul" is that non-physical entity that survives the body after death. It is immortal because the passage of death is a physical event. If one were to prove the existence of a new physical thing and call it a soul, it would not match with what is traditionally referred to as the soul.Pardon me, but out of curiosity, why exactly do you need the soul to be non-physical in the first place? What's wrong with a physical soul? — InPitzotl
