An evolutionary defense of solipsism

I am simply 'testing' this argument.

But I take it that simplicity is an epistemic virtue and that other things being equal, we have reason to think the simplest theory about reality that explains all the data is the correct one.

To suppose that there exists a mind and its own mental states is a very simple thesis, for not only is one kind of thing - a mind - supposed to exist, but only one of it is supposed to exist too.

I will suppose, then, that this is the sum total of what exists and see if, by making such assumptions, the job of explaining everything else can be done.

Assume that at first the mind is in random mental states - random sensations and thoughts occur in it. Over enough time a desire to look for patterns will arise and over enough time the thought that 'that which exhibits a pattern is default real' will arise too and will arise at the same time as the desire to look for patterns. And over enough time those two mental states will arise at the same time as two or more sensations - quite by luck - seem to exhibit a pattern. Yes, the odds will be vanishingly tiny - but that doesn't matter. It'll happen eventually. I take myself currently to be 'in reality' for about 16-18 hours at a go, but the first 'glimpse' would have been for a fraction of a second. It would have built, though....like a crystal.

At this point the mind in question will take those sensations to be of a reality and all others to be a dream it is having (which is what we mean by a dream - sensational experiences that we do not consider to be of reality but wholly a product of our own mind). When another sensation arises within the bubbling soup of sensations that seems to cohere with the sensations that the mind took to be of reality, that sensation will also be taken to be of reality and not part of the dreamscape.

Over enough time, the mind will sift those experiences that seem to exhibit a pattern and to cohere with previous experiences and call that set 'reality' (and it will just build indefinitely), and the others will be considered 'dream'.

So, is that possibly the situation we - I - am in? Those sensational experiences that are adaptive - that fit with the pattern I am looking for - will get selected for by my mind as parts of 'reality', whereas those that do not will be deemed dream.

I now take myself to have been in reality - in and out - for about 50 years. This will go on and on as, with enough time, more and more experiences arise that are adaptive - that is, that fit with the evolving narrative (all others continuing to be considered 'dream').

Interesting implication: we (I) will never die. We (I) will just get the impression we have been in reality for longer and longer and longer. You will experience death-like events. But those will be folded into the dreamscape and not considered part of reality. You will only consider those experiences taht continue the story to be reality. And so the story is going to be neverending.

And when we - I - sleep, it may be for trillions of years....eventually a sequence of experiences and thoughts will arise that replicate sufficiently those I had that I considered reality and that continue it....and that will be taken to be the point I awake. And on and on it goes.

it can be noted as well that once the crystal starts to form, it may affect the random flow of thoughts and other sensations, aiding its own building. that is, thoughts and sensations that tend to cause sensations and thoughts that cohere with them will be selected for (where 'selected for' just means 'considered part of reality').

What I have described is just evolution by natural selection, except that it is applied at the level of a mind's sensations, and 'not being selected for' is just a matter of something being considered dream rather than reality. Does the job, does it not?

And this thesis is simpler than supposing that there exists a mind-external physical reality in which evolution by natural selection is occurring.

Is "mind" disembodied?

Yes, I think simplicity demands it must be a mind without a physical body, as a physical body would be less simple than a mind that had no body.

You stand outside the problems of solipsism when you compare them to other conditions.
Banno November 28, 2024 at 03:56 #950497
At the very least you have assumed that there is both mind and time. Time passes when you are asleep.

In what does this process of thinking take place?

And if seconds, days, years pass, then there must also be a clock or some other device external to mind, the periodicity of which can be contrasted with the series of mental events.

And to whom are you addressing this post?

Clearbury November 28, 2024 at 07:08 #950505
Reply to Banno I have certainly assumed a mind. And perhaps time too - though I am not sure it was essential that I do so, as I think time too can probably be given the same kind of analysis (not yet sure about it).

But it wouldn't matter if I was assuming time, for that wouldn't make the thesis more complicated than its non-solipsistic alternative. That is, I think that any theory about how things have come to be how they are, would probably need to assume time. And so that I have assumed time does not - not in itself - make the theory unnecessarily complicated.
Clearbury December 01, 2024 at 00:39 #950995
Upon further reflection, I think this evolutionary vindication of solipsism can be simplified further.

All that needs to be supposed in order to be able to account for all else, is a mind that is having (initially) random experiences and a disposition in that mind for it to recall an experience - and thereby to have that experience again - when that experience seems to resemble sufficiently another.

Here's what I mean. Let's say the mind has experience A, and then experience B - and experience B seems closely to resemble experience A. Now the mind becomes disposed to experience B again if it ever experiences A again. Then later - and this will eventually happen, of course - the mind will have the experience of B and it will be followed by C, an experience that seems to resemble B. So now the mind has become disposed to experience B if it ever experiences A again (and it will, of course), and then to experience C (for this is what it is disposed to experience if it ever experiences B again, which it will). And thus when the mind next experiences A, it will experience A-B-C. And this sequence of experiences will closely resemble one another.

Over time the mind will develop a disposition to experience B, then C, then D, then E and so on, when it experiences A again. And that's what is going on - this sequence of experiences is just a very long chain. And there we have it: everything that needs to be explained has been explained by just positing a mind, a disposition, and random experiences.  
Clearbury December 01, 2024 at 00:56 #951006
I think this has the same implication as before though: that this is going to turn out to be a neverending story, though one that will start over and over and over, getting longer and longer every time it restarts.

Why does the mind have a start, but not an end? Shouldn't it be infinite in both directions, past and future?
Clearbury December 01, 2024 at 01:15 #951013
Reply to RogueAI I don't think it does have a start. i admit that the idea of there being something that exists eternally is probably problematic. But I think the idea of there being something that came into existence is probably as, if not more, problematic (as that would involve the mind coming into being from nothing....which seems more problematic than the idea of something just existing forever).

As I see it, the account I am working on is not an attempt to explain everything. It is an attempt to explain as much as possible with as little as possible. So i posit a mind (which is unexplained) and a disposition to recall experiences that resemble one another sufficiently - which is also unexplained - and a process of the mind churning through random thoughts (a process that is also unexplained).

The account presupposes such things, rather than explaining them. And I don't deny that's a deficit as there's reason to want an explanation of those things too. But as i see it, the account nevertheless explains all else with those 3 posits, and so is simpler than competitors. Other things being equal, this is a simpler explanation of the nature of what's going on than, say, one that posits a physical world in which there is evolution by natural selection. There's more clutter with that explanation than there is with the solipsistic one, it seems to me, plus the physicalist explanation has us take our experiences to be 'of' a world outside, which is to make an assumption - one that introduces a lot of clutter - beyond what the solipsistic one does.
Clearbury December 01, 2024 at 01:42 #951022
Reply to RogueAI I should adjust my view a little, for if I am wrong and the idea of a mind coming into being is less problematic a starting assumption than the assumption of a mind that comes into being from nothing, or that somehow brings itself into being, then I will simply make those assumptions instead. I think that it still has the neverending story implication, though i admit that it would need to be framed as an 'other things being equal' implication - so, as long as the mind persists, this is what will happen. Having said this, that is probably the implication of the original thesis too, as even if the mind has always existed, that does not strictly entail that it always will. So I will modify the implication: other things being equal, this is a neverending story in that, so long as the mind whose experiences it is composed of persists, the story is fated to start over and over and get longer every time...potentially for an infinite amount of time.

I think that's not a bad assumption. Any theory competing with yours also has the problem of creation ex nihilo. I think mind is a better candidate for eternal existence or uncaused cause than a physical universe. Also, I wonder if this mind you're describing isn't going to eventually turn into a godly cosmic mind, as you shore up the theory.
Clearbury December 01, 2024 at 22:44 #951155
Reply to RogueAI I am not sure. As this is a solipsistic theory, then I am the mind in question and I do not seem to be a god. The theory would need to explain my apparent lack of power, not confer on me more power than I have.

In fact, on reflection this is an attempt to explain the appearance of order by appeal to random processes and a single disposition, and so like the more familiar evolutionary theories, it dispenses with the need for there to be a designer or any kind of guiding hand. Admittedly, there turns out to be a mind at the heart of it all, but the mind in question - my mind - seems as much a victim of its circumstances as it would be under a physicalist alternative. For my mind is just the venue in which random processes play out and become, due to the associative disposition, sufficiently similar to one another that they appear to me, the experiencer, to be describing a place.

Even the small amount of control that I seem to me to have over matters, will turn out to be illusory on this view. For my experience of, say, willing my arm (or 'arm', as there is no arm there in reality, just a certain sort of experience) to move, will not have caused the arm to move. As the only reason why I have the experience of the arm moving in accordance with my willing experience is that these two experiences have been had before and one seemed to be sufficiently similar to the previous one for my mind, having experienced one again, to recal the other and thereby to bring it to mind.

I turn out to be even more a victim of my circumstances on this analysis than I would be on a physicalist analysis, and so in a way even less godly, even though everything that exists apart from me myself, exists as states of my own mind. I am the venue for it all, but not the controller, for what's controlling matters is just that single associative disposition (which I have no control over having). It disposes me to recall similar experiences, but as I do not 'will' it to do so, I am powerless (though will appear, due to willings themselves being experiences and so capable of being similar to one another), though will appear to have some power.

And this thesis is simpler than supposing that there exists a mind-external physical reality in which evolution by natural selection is occurring.


The idea that only one mind exists is not simpler than the idea that only one substance exists. Any monism is simpler than the dualism assumed in a "mind-external physical reality".

But is mental monism simpler than physical or neutral monism? The latter two seem far more plausible, because of the genetic evolution required for background capacities to arise before anything resembling a mind could begin to identify objects and states of affairs.

I accept a case is needed for thinking that mind monism is simpler than physical monism, but I don't see that you've made a case there for thinking physical monism is simpler. Appealing to evolution is not going to do it, as I am appealing to that too. My account is an evolutionary one.

I will use the traditional terminology of materialist monism and immaterialist monism. The materialist monist posits one kind of substance: material substance. The immaterialist posits one kind of substance: immaterialist substance. So far, one is as simple as the other.

But in order to get the job done, the materialist monist needs to posit not just one kind of substance, but lots of particular instances of it. I am defending solipsist immaterialist monism, not just immaterialist monism. I am positing ONE mind. So, one instance of the kind of substance in question.

Perhaps this is what the materialist monist can do too, though it is hard to see how given that their whole story depends on material objects interacting with another. So it looks as if one needs at least two to get things going.

So immaterialist solipsist monism does seem to me to be simpler, and thus rationally to be preferred. It posits one instance of one kind of thing, not many instances of one kind of thing.

It can also be noted that what it posits - a mind, one's own - is a thing of a kind we know for certain to exist. By contrast, material objects are speculative. Yes, perhaps my own mind is such a thing, just one that has conscious states. I do not rule out the possibility. But that is all it is: a possibility (and disputed at that). Until the matter is settled, then positing that there is something more basic that my mind is made of is to go beyond the evidence.

I say this, because even if the two types of monism are in one sense no more or less complex than one another, the above consideration breaks ties.

It's speculative only for those who assume that they never see the world, only their own mental representations. Yet we don't usually doubt what we see. Under ordinary conditions of observation, I've never found a good reason to doubt the existence of what I see, nor the experience in my mind when seeing it.

We're talking about 'things'. Types of thing and number. You're either positing more kinds of thing than I am (if 'electromagnitism' is a thing - which it isn't, of course) or a greater number of one kind of thing. Either way, your theory is more complex than mine.

I am familiar with Searle's view. I don't think you've addressed my points. My theory posits a mind and a disposition in that mind to produce similar mental states to whatever mental state it starts out being in. That's incredibly simple. One kind of thing and just one of it. And one disposition. You're clearly assuming loads more. It seems - given that you think there are more than just two kinds of entity - that you're assuming (by your own view, not mine) numerous kinds of thing, and also very many instances of them. All of that is assumed 'before' the evolutionary processes are then invoked to explain all else. All I assume is one mind and one disposition.

You don't help your own cause by supposing that in addition to physical entities there is something called 'eletromagnitism' - that complicates matters and doesn't simplify at all.

Likewise, you have not simplified matters if you get minds out of matter, for we all have to start with something. I am starting with a mind. You're not. But it is no virtue to have been able to explain how minds arose by supposing a very complicated backstory involving the interaction two or more kinds of thing. That's a vice.

Reply to Janus That's a different point. My point is that my thesis is simpler than the alternative. That is what jkop is disputing.

Other things being equal, we have reason to suppose the simpler of two theses to be true. There is no claim there that this is a guarantee of truth. And we can wonder why the simpler would be more likely to be true. But that we have more reason to think the simpler of two theses is true is not what's in dispute here.

No, I posit a physical world in which things evolve (including minds). You posit a mental world (the mind of the solipsist) in which experiences and patterns evolve. Neither is more simple than the other. Just think about it, it would take billions of experiences to evolve a mental world in the solipsist's mind. Unlike my appeal to evolution, you just assume that a mind exists without reason.

That's a false dichotomy. A physical monism is not limited to descriptions of "extended" matter but also energy, time, space, information, processes, emergence, consciousness, intentionality, words etc. It makes little sense to categorize everything as either "extended" or "unextended". Do you understand this?

The most simple world is one that contains practically nothing. A solipsist with an empty mind is a very simple "world", I grant you that. But also the physical world in a maximum state of cosmic inflation is simple in the sense that nothing happens, until it bursts into yet another big bang.



jkop December 04, 2024 at 11:19 #951595
Reply to Clearbury

Speaking of cosmic inflation and the idea that things are either extended or unextended... Consider Roger Penrose's suggestion that the universe expands and eventually reaches a state in which all matter is dispersed so that there is practically no difference between things being extended hundreds of billions of light years away or unextended in the here and now. A sort of collapse of spacetime, which causes all of the universe's energy and forces to explode as yet another big bang, followed by yet another spacetime expansion etc.

On this account, physical monism may describe the existence of a state in which spacetime has no practical meaning, and the world is practically unextended and simple (in terms of "things", "types" and "number").

You are proposing various possible conditions for our experience. Solipsism imagines there is no way to verify other beings because they have to be produced by my activity.

Such a thought is not capable of comparison with other proposed conditions. Comparisons require standing outside of all the candidates in order to judge which is the case.

That 'standing outside' collapses the premise of solipsism.

That's a strawman. Solipsism is the view that only one mind exists. What I am arguing is that we can explain what needs to be explained more efficiently using that minimal posit than we can by supposing there to be something non-mental, such lots of extended objects (perhaps the mind is an extended object - but the same applies)

Reply to jkop But how can something unextended 'expand'?

On reflection, it doesn't even matter if we suppose only extended things to exist, for the solipsist thesis is still the simpler one. If the single mind I am positing is an extended thing (I see no reason to suppose it is, so this is just for the sake of argument), then nevertheless, by supposing that it has the disposition i described - the disposition for it to put itself in a mental state that closely resembles the one it starts out being in - then all the work can be done.

I don't think that can be true as that generates an infinite regress. So unless we say that every assumption is as reasonable as any and all others, then some assumptions have to be acknowledged to be self-evidently true. That is, our reason represents them directly to be true, rather than us having to infer their truth from other representations of reason.

For example, the claim that, other things being equal, we have reason to believe a simpler thesis is true, is itself a self-evident truth of reason (or 'apparent' one, as we shouldn't rule out the possiblity it may be false). So, the assumption that the simpler thesis is true is more reasonable than the assumption that the more complicated theory is default true.

But these issues take us too far afield, I think. All I am doing is testing whether the solipsist evolutionary theory really is the simpler one. What status the epistemic virtue of simplicity has, how it vies with other virtues, is another matter.

Reply to Paine It's what the term means. And that's how I am using it. Solipsism is the view that one mind - and one mind alone - exists.

it's not even a view about what minds are made of, as it is entirely compatible with physicalism about minds.

Monism is the view that one kind of stuff exists. The two are not equivalent, for there is no inconsistency in holding that only one mind exists but that the mind in question is made of two kinds of stuff.

Simplicity speaks against that and so it is implicit in my case that the mind that is being posited is a simple thing and not a complex thing.

The point, though, is that solipsism has a very long and well established meaning: it is the view that only one mind exists. But please do not drive this discussion into a discussion of the use and abuse of the term solipsism. That is a linguistic matter and not a philosophical one and it is the philosophical case for thinking that there is one mind and one mind alone that I am interested in testing the credibility of.

I think you have missed the point. Posits are not expalined, that's what makes them posits. Positing two things is more complicated than positing one, other things being equal. thus, I posit one thing - a mind - and I see how far I can go with it.

Whether the mind is a material or immaterial thing is actually beside the point. If you posit a material mind then you have not explained it, but posited it. If you posit an immaterial mind then you have not explained it but posited it. If you posit non-mental material things then you have posited them and not explained them. And so on.

That seems false and also not to provide us with a reason to think it solipsism false.

It is not psychologically impossible to believe that you are the only mind in existence. It may not be a very reasonable view - though that's what is at issue - but there is nothing impossible about it. If you are in any doubt about this, just imagine what you'd believe if you woke up as the sole survivor of a nuclear holocaust. You'd believe you're the only mind in existence. That's to believe solipsism is true. It's entirely psychologically possible to believe it, then.

But more importantly, being psychologically incapable of beileving something is not evidence that the proposition in question is false. I find myself psychologically incapable of believing I will die. But that is not evidence I am immortal.

But how can something unextended 'expand'?


When one instance of the extended universe collapses into an unextended nothingness, the following compression of all remaining energy and forces causes an explosion (big bang), and the explosion creates a new instance of extension. When it cools down, atoms begin to form, followed by the compounds of matter and things.

Clearbury December 05, 2024 at 04:43 #951797
Reply to jkop But only something that occupies some space can expand, as there needs to be the space it occupies and then expands into. So something that is not extended in space is not capable of 'expanding' except in some metaphorical sense.

I think this is all beside the main point though. The solipsist evolutionary theory posits one kind of a thing (a mind) and one disposition (the disposition to create a similar mental state to the one it is originally in) and gets everything out of that. I still do not see how an alternative that starts with something else is going to be able to explain as much with as little.

I think you have missed the point. Posits are not expalined, that's what makes them posits. Positing two things is more complicated than positing one, other things being equal. thus, I posit one thing - a mind - and I see how far I can go with it.


Your idea of mind seem to be coming from some sort of dualism. That's fine. But my idea of mind is based on the mind as a function of body. That means mind without body is impossible. As soon as body dies, mind dies also by necessity.

In this situation, the question naturally arises, and need to be explained i.e. how mind can exist and operate without body. This is a quite complicated process I would imagine.

If the mind without body arguments keeps going on without clearing the inevitable question first, then it would sound like a paranormal rants. We want to avoid that.

Unlike a balloon, the universe has no outside into which it can expand. It creates the space.

The problem is that you don't explain anything, you only say that you do, while dismissing and ignoring the objections. That's disingenuous.

Reply to Corvus The issue does not seem to be what kind of a thing the mind is. It does not matter for simplicity's sake whether minds are material or immaterial. What make the thesis simple is that only one kind of a thing is posited - whatever kind of a thing a mind is - and only one instance of that kind of thing is posited.

I can make no sense of that. You haven't explained how something non-physical can expand. Something cannot expand if there is no space for it to expand into. And space cannot expand unless there is space for it to expand into.

As I say, you are either using the word 'expand' in some metaphorical sense, or you mean it literally, but it you mean it literally then you are just talking about material entities and the space they occupy.

The issue here is simplicity. The thesis I have put forward is simple. To challenge that claim of mine, one would need to argue that there is an 'as' simple thesis that does just as good a job at explaining everything.

I don't think there is. Note what you have to do. You have to posit one thing. Just one. And you have to attribute to it one simple disposition. Just one. And you have to attribute to it one state. From those elements, you need to derive everything else. The solipsist evolutionary theory I have proposed does that. It explains how experiences of the kind I am currently having could have arisen given just those three elements: one thing, one state of that thing, and one disposition.

Another problem with disembodied mind is that, it is devoid of all the sensory perceptions, which is the source of thoughts, feelings and sensations on the external world. It has no linguistic apparatus either which is closely linked to logic and reasoning. All it could do is dreaming, but dreaming is only possible via brain. With no bodily organs available to the mind, we wonder how it could even dream, imagine or even have illusions and hallucination.

The OP title says it is "an evolutionary defense", hence some counter arguments is being presented against the OP's assumptions.

What's being posited is a mind that is in a mental state - so, whatever total mental mental state you are in now (including all experiential states), just assume the mind is in it.

There is no need to assume that the mind has a physical substratum. To think you do have to make that assumption is already to have assumed physicalism. And whether physicalism is true is the issue.

So, just assume a mind in a mental state. Now assume the mind has one disposition: to put itself in a mental state that closely resembles the one it is already in. So, its disposition is just to replicate the state it is in but it makes small changes every time it does this. That gets the job done. That's what this is (or could be).

So whence comes a theory of evolution worth considering in light of this posit?


Clearbury December 08, 2024 at 22:57 #952507
Reply to wonderer1 Admittedly, my theory has changed slightly as it is now simpler than the original.

But the original evolutionary story involves random mental state generation and a mind disposed to remember sequences of mental states that seem closely to resemble one another. It experiences A. Then later it experiences - by random (and with enough time this would happen, of course) - B, a state that seems very similar to A. This it remembers and is now disposed, should it ever experience A again, to experience B following it, as it has a disposition to recall what it has remembered.

Eventually B will be experienced being followed by C, a state that closely resembles it. And now the sequence A, B C is remembered and should the mind ever experience A again - which it will given enough time, it will experience A, B, C. And so on.

In this way a potentially infinite sequence of closely resembling states can evolve. And the idea is that this is what 'this' is.

But now I have simplified it further. The standard theory of evolution has physical things replicating themselves with random mutations. Ok, so i will simply posit a mind that is disposed to replicate its initial mental state but with random changes. And that is what this is. That's simpler still. Both theories are simpler than the standard evolutionary alternatives, but the latest is the simplest of all and it seems to get the job done by positing one mind, one initial state of that mind, and one disposition.

The biological theory of evolution is based on all sort of empirical evidence. Is empirical evidence for your theory of evolution even possible in principal?

All that quote from Russell does is reveal how illogical Mrs Christine Ladd-Franklin is. That is, it reveals that she's not very good at understanding the implications of a thesis - which is surprising in a logician. Russell is making fun of Ladd-Franklin, not making fun of solipsism.


Your definition of solipsism equates to eastern philosophies such as Brahmanism and mind only Buddhism and Western philosophies such as Neoplatonism. In their various ways they posit that there is only one mind and that the supposed existence of many minds is an illusion. On that view Ladd-Franklin is not being illogical at all. It is only in relation to the standard solipsism which says that only my mind exists and that all you others are mere projections of my mind that she is being illogical.
Clearbury December 08, 2024 at 23:54 #952519
Reply to wonderer1 It's based on simplicity. Both theories are explaining the same data - the empirical data. But the standard evolutionary theory posits lots and lots of replicating and randomly mutating entities, wheres my theory posits one mind replicating and randomly mutating its mental state.

She is being illogical as solipsism is the view that only one mind exists. So a person who thinks it is surprising that there are not other persons who are solipsists is being illogical, as by hypothesis there can only ever be one solipsist if solipsism is true.

No, you are still missing the point. If there is only one mind and that mind belongs to just one person (which in this case would be the woman in question) then on the face of it what you say might be true. But if there is only one mind and that mind is god or brahman or some kind of universal or collective mind and we are all illusory separate minds then, in that case, you could logically have many solipsists who would all be wrong if they though they were uniquely the one true mind.

Even positing ordinary solipsism, you can have as many solipsists as you like but only one can be the one true mind and thus be correct in their solipsism. All the others would be mistaken.

What is the purpose for doing this? What is the solipsism trying to prove?
Clearbury December 10, 2024 at 23:00 #952881
Reply to Janus No, for solipsism - as I keep saying - is the thesis that only one mind exists. That's certainly how Russell was understanding the term (else his joke makes no sense) and how he was assuming everyone else understood the term and how I am using the term.

Note: the idea that there is only one mind and that there are also lots of mind is straightforwardly contradictory. It does not answer to the meaning of the word 'solipsism' and it is not coherent. It's also clearly not what I am talking about or what Russell is talking about.

I don't think I can discuss this with you any longer. If you want to insist upon understanding the term solipsism incorrectly, that is entirely up to you. But I am not interested in discussing matters further with someone who insists upon using terms incorrectly as you're just going to keep strawmaning the view I am trying to defend, which is tedious.

My purpose is to try and figure out what's going on. And 'solipsism' isn't trying to prove anything. It's a thesis. I am the prover. And I'm not really trying to 'prove' it, just show that it is a simpler thesis than its nearest rival. Whether that proves it - that is, puts its truth beyond all reasonable doubt - is another matter, as simplicity is only one epistemic virtue not all of them.

Why not solipsism with the mind in a body, or mind and body? You keep emphasising on simplicity, but simplicity can degenerate into the vacuous assertions.

Clearbury December 11, 2024 at 01:39 #952909
Reply to Corvus Your question answers itself. It is simpler to suppose a mind to exist by itself than it is to suppose it exists in a body, for then you're not assuming a body too.
Corvus December 11, 2024 at 09:55 #952963
The question does not answer itself. It implies that mind without body is an unintelligible assumption, which generates the vacuous assertion. It asks if solipsism would make more sense if it assumed mind in body.

Reply to Corvus I do not follow you. I am positing one kind of thing - a mind - and one instance of it.

Now, it is clearly conceivable that minds can exist without any material entities existing. There is nothing incoherent in the idea.

But even if minds can't exist without a material entity existing, that doesn't affect my case, as I'm still only positing one kind of thing and one instance of it.

Whether minds can exist apart from material bodies or not is a red herring. The issue is whether, by just positing one mind in one kind of mental state and with one disposition, we can get the work done of explaining all else. That's the issue.

I am not trying to make you follow me.   I am just saying there are some questions rising from the OP, and further your assertions, which are getting more mysterious and even spooky.

You claim that you posited a single mind for a single instance.  But is mind something which can be posited?  Is it your own mind, or someone else's mind which you posited?  How did you do that, if that operation had been done?

Because from my understanding, one can only be conscious of one's own mind, and no one else's.
If it were your mind, then how does your body function without the mind, which is posited to the OP or to some other location or storage? 

As your staunch claim, if your body doesn't exist, because it is disembodied from the mind, then how were you able to read my posts without the sights, and replied to them with no hands and fingers to type up?

The mind I posit has a disposition to replicate its state with small changes. So it starts in a state and this starting state causes the mind to be in a subsequent state, a state which will be extremely similar to the previous one. And on and on it goes. Nothing is stored.
