An evolutionary defense of solipsism

Clearbury

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?

Clearbury

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

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

↪Paine

I am not sure I follow your point.

Clearbury

↪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

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.

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.

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').

Why does the mind have a start, but not an end? Shouldn't it be infinite in both directions, past and future?

Clearbury

↪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.

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.
