Can you prove solipsism true?
Something that crossed my mind, though my reasoning says no. I checked this link that said it did but it was bad logic that didn't really follow and made a bunch of assumptions it couldn't prove. You wanted to confirm if that's the case or if I'm wrong.

Second one doesn't really add anything but I figure I'd add it.
https://qr.ae/prbTtt
I'm asking because years ago I thought I saw a post on quora that proved solipsism to be true and I suffered since then. But I don't remember what it said or even if it was right (I'm pretty bad at philosophy) and I can't find the post. So I've lived thinking it's true this whole time and there isn't a reason to connect with people because they aren't real. But if solipsism is unproveable then he's wrong and I can move on.
I thought that it's unproveable like the simulation hypothesis because there's no way to get outside of it to know for sure.

Who are you asking?
This assumes that there is only my view of how things are.
At least you are consistent.
So Im wondering what kind of proof its supposed to be
I think you're right. Solipsism is like the simulation hypothesis. If you are correct that they are unprovable, and I think you are, then they're metaphysics, not science. You're fairly new here. I don't know if you've heard my metaphysics spiel, which is similar to that described by R.G. Collingwood in his "Essay on Metaphysics." Metaphysical statements are not true or false. They have no truth value. They are the underlying assumptions, Collingwood called them "absolute presuppositions," that underlie our understanding of the nature of reality. They are the foundations of science.
Generally proofs of this sort are muddled improvisations in the rationalist or scholastic style.
Arguments for idealism and solipsism take it as granted that statements are beliefs, that "The kettle is boiling" is the same as "I believe that the kettle is boiling". They make the error of thinking that the game of truth and falsity is the same as the game of belief. But one can believe things that are wrong, believe that the kettle is boiling when it isn't.
That we are sometimes wrong, that we learn new things, that the world contains surprises, that we feel embarrassment, pride, shame... these things display the error in solipsism.
I am not familiar with it. There are many approaches to metaphysics. Given my strong attachment to the views of Collingwood, what does Watkins have to offer.
I had rather than you in mind, sorry. It's an approach after Popper, so based on received notions of scientific method, and in a more concise and readily available form. It also, from what I've read of Collingwood, it appears to take a more logically formal approach.
But both swings and roundabouts take us back to where we started.
I started a thread a few months ago about my belief that others exist for sure, but not me à la Cotard's delusion (the mirror image of Descartes' cogito).
You do realise that that's not what solipsism says, Smith? Not I exist, but I alone exist.
:ok: I didn't know, but can you review Cartesian skepticism and get back to me if you find anything interesting.
A Deuteronomy of Kant-Friesian Metaphysics
When the Neo-Kantians, or Hegel, eliminated things in themselves, the result was directly, starkly, and unambiguously solipsism. Hegel avoided that only by making consciousness collective and universal, an "Over Mind," the "Absolute Idea," in which individual existence dissolves like sugar in coffee.
The sticking point is the conclusion that Kant's theory forces upon us, that the "real things" of the world are both external objects and the internal contents of consciousness.
1. Only things that we're 100% certain exists exist.
2. The only thing I'm 100% certain exists is me (re cogito).
Ergo,
3. I alone exist.
QED
:lol:
P. S. I suffer from Cotard's delusion (I don't exist).
That being in a solipsistic state causes the other intersubjectives to 'come get you /poison you' does not disprove solipsism, just perhaps that you are not god/ originator of all law. That intersubjectives are anti-solipsistic does not prove they are expressing god's will, but is perhaps the fundamental lesson of this experience which all philosophy seems to be about.
1.The 3 marks of existence are anicca (impermanence), anatta (no-self), and dukkha (suffering).
2. I alone bear these 3 marks[sup]A[/sup]
Ergo,
3. I alone exist
QED
A: Some are anicca but neither anatta nor dukkha; others are anatta but neither anicca nor dukkha; still others are dukkha but neither anicca nor anatta. In no person/thing in our universe do the 3 marks of existence instantiate simultaneously except in me. :grin:

[quote=William of Occam]Pluralitas non est ponenda sine necessitate[/quote]
Ergo,
Ego solus est.
I think that quora post I read years ago is mistake or I was. I mean I you cant prove solipsism, how can you prove youre the only mind in existence if you cant even measure minds, let alone know of somewhere in the universe there is another. Or how do you know youre not just someones dream or simulation. It seems like any attempt to prove it would involve so many assumptions that you cant back it.
Then there is also that wrinkle about posting it on a public forum for people to read.
And it also assumes that you exist and are thinking and a bunch of other things it cant prove.
I was going to ask: prove to whom? What would be the point of trying to prove it to yourself?
Though I dont really regard solipsism as highly as in the years past because a lot of the explanations for people who prove it are straight nonsense like this:
Solipsism is about knowledge (epistemology) and not ontology (metaphysics). The only proof that's for sale is what can be known to exist (with certainty). The project won't fly mon ami.
It's why you can never prove solipsism, though I'm slowing getting over it and seeing how it's not really logical (consistent sure but not something to be taken seriously or at all since it says nothing and advances nothing).
But as I quoted above, those who try to prove it just end up making a whole bunch of assumptions they can't prove, like events only happen if you're looking at it which is nonsense, otherwise car crashes wouldnt happen.
Sure, and some of these are certain. So to be reading this text, you have to take a range of things as granted: that I am writing this in English, in response to your post, addressing your concerns, which you recall and can also check by looking at your previous posts... and so on. That you continue to read this post puts the lie to doubt.
We make a big thing of having reasons for being certain. Somethings, including those listed, we take as granted, unless we see reason for doubt. We've learned a bias towards needing proof, failing to notice that some things are indubitable. What reason have you for doubting that this sentence is in English? How could such a doubt be reasonable?
Which is why I'm heavily doubting not just my memory about what I read those years ago but if they actually did. But all I have is a very strong emotion that he certainly did but no memory of what was said, which means nothing.
I don't think we have a learned bias towards needing proof, quite the opposite actually. In fact we fail to notice how much we take for GRANTED in our lives. Like that we exist, we just take it as a given never questioning it, yet when asked to prove it you can't without something self referential or just flat assertions.
The arguments I offered rely on either principles (novacula Occami) or definitions (3 marks of existence & epistemically-limited ontology). You may indeed question their legitimacy.
What I find intriguing is that as @Banno so insightfully inquired as to who the proof is meant for, a person X,
attempting to prove solipsism implies
1. X exists (as the target of the proof) [re cogito ergo sum]. Proof serves the same function as thought/doubt.
And
X succeeding to prove solipsism implies
2. Others don't exist.
I don't think metaphysics is transcendence of the physical. It isn't confined to the physical though. Also I did argue from an epistemo-ontological view (re Idealism).
1) Metaphysical (M)
2) Epistemological (E)
3) Psychological (P)
Initially, it seems that your post concerns E solipsism, in asking "How can one know whether or not one's mind is all that exists?". Thus buried in this question are a concept and a presupposition, namely that one is using a closed a-priori definition as to what one means by one's mind, relative to which one is asking whether there exists a type of evidence, that if observable to ones mind, settles the question as to whether one's mind is all that exists.
M solipsism on other other hand, isn't a presupposition, but a refusal to grant intelligibility to the idea that there exists anything outside of one's mind. This entails that one's mind isn't meant as a closed and static concept that is a priori definable, but as an open and adaptive concept that is rationally and empirically exhaustive of one's concepts and potential experiences to the point of closing off the domain of philosophical and epistemological inquiry.
Philosophies that are sympathetic towards M solipsism are phenomenalism and empiricism. We might recall Berkeley, who rejected the conceivability of an unobserved and unimagined tree, Wittgenstein who questioned the intelligibility of the distinction of idealism and realism, and Charles Sanders Pierce who considered the external world to be congealed mind. These philosophers weren't speculating that mind is an exhaustive substance, as when an E solipsist and his naive-realist opponent considers mentality to be an object for propositional analysis. Rather, those philosophers treated mentality as a meta-linguistic activity that is the very basis of any act of rational and empirical enquiry.
As such, it doesn't make sense to argue for or against M-solipsism, as an M-solipsist will always interpret the arguments of any purported opponent or critic M-solipsistically. Indeed an M-solipsist might even identify as a realist for all epistemological purposes.
P solipsism is a ruminative psychological condition experienced by amateur philosophers and isolated individuals such as astronauts, who mistake their narrow a priori self-concept for the world. Anyone who self-identifies as an M-solipsist runs the risk of experiencing this condition as a result of misunderstanding the meaning of M-solipsism.
Taking solipsism as knowledge of anything outside one's own mind is impossible
I want to prove the proposition P that solipsism is false.
Start by assuming that Solipsism is true.
Assertion one: I have knowledge of the novel Don Quixote, but as knowledge of anything outside my mind is impossible, only my own mind could have created Don Quixote, and therefore I am a great writer.
Assertion two: this post fails to convince me that this is the best argument to prove that solipsism is false, therefore I am not a great writer.
As assertions one and two are contradictory, by the law of noncontradiction, proposition P is in fact true, ie, solipsism is false.
Il est facile de voir que ... I don't exist!
So how does something that I know about but am not conscious of become something that I am conscious of.
If solipsism is true, only I could have decided to be conscious of something that I was previously not conscious of. But if I was not previously conscious of something, how could I know to become conscious of it. The solipsist needs to explain how I can become conscious of something that I was not previously conscious of.
Pure solipsism is not a challenging philosophical exercise. You don't have to have any JTB about any of the things that you mention, they are merely objects of your creation that mean whatever you want them to. Everything that is, is possibly interpretable by an 'idea of reference' that relates to you. About you or against you. You immediately understand everything as if it orbits around you like a planet around the sun. Better yet, geocentric is more solipsistic than heliocentric.
Obviously some manifestations of solipsism can be deemed false/untrue/dysfunctional, but ultimately it has a power whether you call it will-to-power or something else, that is opposed to group-think, consensus, democracy, fascism, normativity, herd mentality, objectivity, collectivism, state-philosophy, psychiatry, etc.
The title of the thread is "Can you prove solipsism true?"
Yes, an argument that refutes an absolutist metaphysical solipsism also leads to a refutation of sceptical epistemological solipsism. Indirect Realism is not a form of solipsism.
It does, and it has. It may not be true by modern philosophical ideals, but it is a true force of nature.
Quoting RussellA
I didn't say that it was. However, indirect realism is the underlying phenomenon.
Not true at all. It's not true just because it resides in all of us. And it definitely isn't a verifiable act of psychology (which suggests the opposite).
Not to mention not of your logic follows or makes any sense.
Still wrong, again.
Berkley can argue against and unobserved and unimagined tree all he wants it doesn't make it any less real. It's also why idealism died out I guess and why we follow science. The "if I don't see it it didn't happen or isn't real" is one of the easiest things to disprove.
Everything else you said is irrelevant to the topic.
Its just another unprovable and untestable claim just like simulation
I thought I proved ... something. I quite like me proofs. :smile:
Like people said about my first post with that proof, it's nonsense.
Quoting unenlightened
...and then the need for a proof seems moot.
I intelligo.
I take up your challenge. :smile:
The argument is:
1) Only things that we're 100% certain exists exist.
2) The only thing I'm 100% certain exists is me (re cogito).
3) Ergo, I alone exist.
There are two parts to statement 1). The first part is "Only things that we're 100% certain exists". Name this first part X. The second part is "X exist".
The problem is what exactly is "exist" referring to.
As regards the first part of statement 1), as the only things that I'm 100% certain exist are my thoughts, such as my thought about apples, therefore, exists must be referring to what exists in my mind.
As regards the second part of statement 1), X exist, what is exist referring to, what is in my mind or what is outside my mind, apples existing as thoughts in my mind or apples existing in the world independently of my mind.
If exist is referring to what is in my mind, then 1) is tautological, in that thoughts about apples that exist in my mind exist in my mind as thoughts about apples. If exist is referring to what is outside my mind, then 1) is saying that the things that I am thinking about, such as apples, exist outside my mind. But this is an unjustified statement.
Therefore, statement 1) is the problem, in that it is either tautological or unjustified.
That's a very un-Pyrrhonist thing to say, you sound very certain about it.
I'm not certain and hence I'm a Pyrrhonist.
Are you certain that you're a Pyrrhomist ?
Yes.
Hopefully, the following argument uses no assumptions anyone would disagree with.
An argument for Solipsism
Everything I perceive in the world outside my mind happened in the past, whether the position of the moon or a leaf falling from a tree.
On the one hand, as I am always perceiving something that happened in the past, I am perceiving something that no longer exists, and to perceive something that no longer exists could be said to be perceiving an illusion.
On the other hand, I can imagine that what I am perceiving in the past continues to exist into the present. But what I am imagining is not the actual thing but a fictional account of it, and to imagine something that may or may not exist could be said to be perceiving a fiction.
Either way, everything I perceive existing in the world is either an illusion from the past or a fiction about the future.
Solipsism holds that only one's own mind is sure to exist. If my only knowledge about what exists in the world is either an illusion or a fiction, how can I be sure about any existence outside my mind, and isn't this what solipsism is saying.
You appear to have false preconceptions regarding Berkeley's position. I'd recommend studying the SEP article before continuing discussion.
Also everything you are perceiving is in the now. Not the past. Even a memory of the past is still in the now. You arent imagining a fictional account either but the real thing.
Without any reality as a comparison the word illusion is meaningless. Solipsism ASSUMES ones own mind is sure to exist. While in the process using words, concepts, etc that originate outside of the mind. Solipsism fails to prove the existence is a mind that it assumes to know for sure exists.
None of your points follow either and they assume too much, much like my original post guy did in his link.
Like I said before all arguments for it boil to nonsense since you have to deny solipsism to prove it and rely on things outside of it.
Plus unless you can show a clear difference between a simulation and the real thing then theyre the same and the point is null.
Solipsism isnt a mental disorder either. Again you are inventing things to make it other than it is.
As for denying any simulation hypothesis from the soul to mind to computer does not cause someone to doubt what is real, compared to direct realism then perhaps Plato and Decartes are not as adept as you.
There's no reason to take it seriously. Unless they can demonstrate said alternate reality it's junk. Even then it wouldn't make this less real. You'd just have two realities. I mean alternate realities are a common trope in media today, even cartoons do it, so I don't see why it would make you question anything. Seems interesting rather than scary.
Quoting introbert
You're getting off track...again. It's far from my original post.
This is the problem of negative singular existence statements, where in order to deny the existence of a given individual, one must assume the existence of that very individual.
Quoting Darkneos
Where is the faulty premise ?
My premise was "Everything I perceive in the world outside my mind happened in the past, whether the position of the moon or a leaf falling from a tree."
It takes time for light to travel from an object to my eyes, whether the 2.54 million years from the Andromeda Galaxy, the 8min 20sec from the Sun, the 1.3 sec from the Moon, as well as the leaf falling from the tree.
The time taken for light to travel from a falling leaf to my eyes may well be small, but it is finite. Pragmatically, it may make no difference to my daily life, but philosophically it does.
Philosophically, it means that it is impossible for me to have any knowledge of what exists in the present outside my mind. I may strongly infer what exists, but it is still an inference, and as only an inference, I can never be sure beyond doubt. I can only ever be sure of what exists in my mind in the present .
As I can only exist in the present, the past no longer exists. Therefore, the only other thing that can exist is the present outside my mind. But as I can only know the present outside my mind by inference, and as an inference is something that I may be wrong about, then is something that I cannot be sure about.
Therefore, the only thing that I can be sure about is the existence of my own mind, which is an argument for Epistemological Solipsism.
Why?
The existence of god, being as rational as possible, is in the hands of the skeptic downgraded to may exist. Yet, atheists immediately take the extreme step to god doesn't exist.
Likewise, we've been able to demote other non-self things to may exist (per solipsism) and il est de voir que ... the other does not exist. Solipsism is then just being an atheist with regard to non-self. :cool:
There is no may be.
:up: On a more serious note, solipsism seems connected to Chalmers' hard problem of consciousness.
Like I said, pro solipsism arguments are nonsense.
But again as stated you cant be sure of your mind in the present let alone you. The fact youre using leaned language that you got outside you is enough to blow that claim away. Try making any argument without language let alone the concepts to argue for solipsism, you cant.
The past does exist, just not in the way you think. The present is also not an inference either. It exists apart from you. The only way for your argument to make any sense is to axiomatically claim that your mind and you dont need a cause, and at that point youve already lost as that would violate Occams razor. Why assume you and your mind are cause less when its more logical to go with realism or the default view.
There really is no logic that can reasonably jump to solipsism. Just because we cant be sure (and to be frank we cant be sure of anything so thats not a metric to use) doesnt mean its all in your head or youre the only conscious thing. Thats not what explains our observations so it doesnt logically follow.
Like I said, faulty premises that assume too many things they cant prove.
To repeat, arguments for solipsism eventually boil down to nonsense. And its why its pure faith, nothing more.
Makes a mental note of that. :up:Quoting Darkneos
Not so mon ami. Solipsism is skepticism's piéce de résistance, but skeptics can do a lot better if you catch me drift.
Again solipsism fails Occams Razor.
They dont even know if theyre thinking or if they exist, both of which are unfounded:
https://youtu.be/SRwMFjCoOUc
:chin: and :smile: Précisément.
SO while it appears to be skepticism it's really just fantasy it's doing.
:up: I'll watch the video later. Danke.
I skimmed through the quora answer; didn't find anything noteworthy.
Solpisism is epistemological and not ontological in nature. It's about what we can know about reality rather than what reality is. Your question is moot.
Epistemological solipsism is the philosophical idea that one can only be sure about the existence of one's own mind. The existence of an external world is not necessarily rejected but one can not be sure of its existence.
You write that "and to be frank we can't be sure of anything", but that is exactly the metric to make the jump to epistemological solipsism.
Your position that "we can't be sure of anything" is the point of epistemological solipsism.
Wrong again bud. Cant be sure of anything just leaves you stuck then. You cant be sure you exist or your mind, you dont jump to solipsism from there. YOU CANT. At least not without leaps of faith like any other philosophy.
The position of not be sure of anything isnt the point of epistemological solipsism (which lets face it is just splitting hairs from metaphysical solipsism). Solipsists are at lest sure they and their mind exist, and yet have no basis for thinking so. They just assume that to be the case.
So still not correct there.
Is it your understanding from the above that assumptions_presuppositions cannot be refuted?
Theres a set of assumptions you have to make about the world, without which you cant do any thing. Even solipsism assumes the subject or mind exists, well that and a lot of other things like assuming the area around them isnt real, that other people dont have minds. It assumes too much that it breaks Occams razor
Quoting Darkneos
Okay. Metaphysics calls for a special type of assumption: an assumption that resembles an axiom.
Everyday assumptions are refutable: We had been working on the assumption that the murder took place after midnight. When the detectives proved it happened before midnight, our defense of the suspect collapsed.
It's moot because ex mea (humble) sententia, it conflates epistemology with metaphysics (ontology).
I don't see it though unless you mean it in a Schopenhaurean Will sense.
But the more you think about it the more of a nothingburger it is. I mean you can't test it, you can't even know, or feel the difference if there even is one, and if there was you'd never know since all you have is your perception so you can't validate it. You'd have to be able to get outside of your perception to do so but that would be invalidating solipsism as soon as you do. So.........................................................
I don't know. I just thinking about it I have to wonder why even think about it?
Well, I dunno about you, but I am confused. Perhaps you need to look at the matter from a different angle, oui?
I see. Good point.
As observers we will still have to struggle in order to survive, seek well being , avoid suffering and many of us will eventually fail.
Like any pseudo philosophical idea (an idea that doesn't succeed in expanding our understanding and wisdom) discussions on Solipsism place should be in a bar with a glass of beer on hand, not in a philosophical forum.
The idea of "simulation hypothesis" was an official attempt to justify the place of soliphism in Philosophy and science but after it was proven wrong (back in the 2017)by science its was dismissed for good.
I'm replying to you because you started this discussion. I hope I'm not being too disruptive by intervening at this late stage. I have read the discussion so far. I hope I can bring something new to it.
The core of the solipsism seems to be I alone exist (call this P). From my point of view, this is clearly empirically false. I can recognize other people and interact with them; my training for this began within minutes of being born, before I could speak or think.
But a solipsist is clearly a person, living in the same world as me. But I an equivalent belief - that other people exist. Certainly refutation or proof of the normal kinds are not available. So this must be a proposition of a different kind hinge, conceptual, grammatical. That does not mean it is trivial. However, I can only decide how serious or trivial it is when I understand it.
It may be that solipsism is based on the observation that I am the subject of my experienes, make my various judgements, have various desires and values and perform various actions. No-one else can do those things. Indeed, some people think that this is what constitutes my self, and similar observations underpin various other ideas in philosophy.
For me, I designates the same thing as my name, namely me. That does not mean a special part of me, but rather the whole of me (although that whole, like other things with parts, can undergo various changes as time goes by.)
So the difference is a difference in the idea of the self, person, human being.
How to understand and evaluate this? Assuming that everything that can be said in one language can also be said in the other, it will come down to different attitudes and ways of interacting with other people. And it will likely be a pragmatic decision.
Other forms say you can only be sure that you exist and everythign else is uncertain but this is the same thing and just splitting hairs.
I don't understand. Do you mean that solipsism consists of just that statement "I alone exist", in two versions, "I exist and nothing else exists" and "I exist and no other person exists".
No reasons, no explanation of what "exists" means or "I" means?
No response to the question what that assertion means if there is no-one to hear it?
Or is it just that each solipsist has their own meaning and reasons?
I have to look again at the links you gave in the beginning.
That seems to be a box with a label but no content.
That is a possibility. I'll think about that.
Well, I can't understand solipsism from a solipsist's point of view, because I have a different hinge (axiom?). Even if I didn't, I still couldn't understand solipsism from any point of view but my own.
Nonetheless, in my reading, both those arguments (I'm not sure if that's the right word for Anonymous' piece, but it certainly is for Barmadosa's) turn on: - Quoting Ludwig V. Or so it seems to me.
You started this discussion because, as you say: - Quoting Darkneos
So we are agreed that solipsism is unproveable.
It might help, though, to think that there doesn't need to be a reason to connect with people. Like all the best things in life, it is something worth doing for it's own sake, and it might reduce your suffering. Elimination of suffering is too much to ask, I'm afraid. That's my experience, at least.
You might be less pleased if I point out that the fact that solipsism is unproveable means that it's undisprovable, as well. But that only means that each solipsist and non-solipsist has to decide for themselves where they stand. I guess solipsists can live with that. (Anonymous, at least, seems to have taken that on board.)
So you are concerned that solipsism might be unprovable but nonetheless true. Historical speculations fall into that class. There could be evidence, but we'll never get it. For example, so we'll never know what Julius Caesar said to Brutus, as he and his friends stabbed him to death. The claim that he said "Even you, my child" is unprovable but might be true.
I was treating solipsism as a hinge proposition or an axiom. It is not like a historical speculation. No evidence will ever be relevant to its status. That's why hinge propositions and axioms are not proved or disproved, but chosen or adopted. One can choose a different hinge, a different axiom. So if solipsism causes you suffering, it is open to you to adopt a different hinge/axiom.
Solipsism could be something as hard to change as a bad habit, and I'm well aware that pressing suggestions on someone who wants to change a habit is not only useless, but offensive. So I wouldn't dream of pressing any suggestion about what to do about solipsism on you.
I can't see how this can be discussed. Do we agree on that?
Well, there's nothing to say, then. Thanks for enlightening me.
