You are performing a reducio ad absurdum, taking solipsism to it's extreme conclusion to refute it. Indirect realism can be reduced to the absurd by taking it to solipsism. However, solipsism is like indirect reality, it is not completely of the mind, but it is a function of the body.
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. — introbert
This is a key topic in the prevailing ethos of anti-schizophrenia. The first issue is that, of course, solipsism is a phenomenon of indirect realism. Indirect realism is not disproven by the solipsistic extreme that the mind originates all reality, neither is Idealism disproven by the existence of the physical realm. Solipsism is a verifiable fact of 'psychology'. Practical knowledge has been developed through the objectification of solipsism, such as 'theory of mind', therefore, through it's existence what is considered normal psychology has not been taken for granted, and some understanding has been developed of epistemology etc. Arguing solipsism is not true, is like arguing idealism is not true, but the difference is that idealism has developed in the modern by the rejection of manifest irrationalities that occur in nature. Solipsism is true because it resides in all of us, it is part of our bodily power, it can help us and it can hurt us. That it is most noticeable, made an object, through its problematic manifestation, and not really noticed when it is functional, arguing against it is an absurd and ironic rational idealism. Ironic, because one is using solipsism in making solipsism purely an idea your mind can deny, without acknowledging that there is a material basis for it outside your mind that is undeniable. This is like a transcendental idealism, but by trying to transcend solipsism, one confines idealism to rational (normative, deindividuating) thought. Ultimately a disempowering belief. This disempowerment, rejection of solipsist negation of other minds, turns one into a mindless extrovert. A mindless extrovert is a fascist, a mindless introvert (solipsist) is a homeless schizo. The Deleuzian concept can be interpreted that the schizo is an oppressed introvert (lone thinker) in a socius of extroversion (collective doers), is about a broader philosophical project that makes the anti-solipsist into a useful marionette, and the solipsist into a tangled mess of strings that only the most powerful can unravel. — introbert
Solipsism is not a choice, human beings or a human being is even in strict scientific terms a subjective entity, a subject, everything that happens to me is in my own subjective bubble. But, this is not where i see where the problem is at. The problem comes when, if you even come to the realization that solipsism is true, and that no event can exist without you consciously being subjectively aware of it, why would a solipsist or any person, put himself inside a simulated reality that basically restricts him in his wishes, fantasies, and absolute freedom. If you are infact first and foremost, outside of the simulated reality and have absolute freedom to do with yourself whatever you want, restricting yourself to a simulation even if it is self imposed, inside one’s own mind is really hard to understand. Because you would basically go into a span of about 80 years, experiencing even suffering, physical or psychological, being restricted in what you can do, example, no absolute control or freedom over matter, or the mind-matter relationship, i agree that it is hard to understand subjectivity and its logic that way. But, still, that does not negate solipsism. Because you also get to experience amazing beautiful things and extend your freedom further to the point of physical liberation or end which results in death, but you only end your own mind simulation. The whole process of solipsism is that every minute, date, month, year and second is a carefully planned event that must ultimately lead to absolute freedom, that is the end point of solipsism, to be able to do whatever you want, and without your subjectivity in that state ever ending.
How does he know other people exist? — Agent Smith
Who said anything about less than? I keep bringing up energy because it exists at the same level you are trying to dismiss as ‘less than’. You can try to ‘dismiss’ a nightmare, but it still exists as part of your experiences. What you’d be doing is trying to exclude, isolate or ignore the experience by devaluing the information it offers. — Possibility
When we read about a character, we treat them as MORE than the description we have. When we interact with a fictional character, we flesh out the limited information we have AS IF they were a living, thinking, feeling human being. — Possibility
The way I see it, ‘not real’ doesn’t mean ‘less than’. Real is a quality of existence, but not necessarily a value judgement. Treating the information we have about other people as ‘not necessarily real as such’, in this world of online forums, social media and AI, is arguably more accurate than being dismissive of any interaction unconfirmed as ‘real’. You can’t be certain that anything you read or observe here about me is ‘real’. I am a ‘useful fiction’ to you, whether you recognise that or not, as you are to me. For me, that means I treat you as MORE than the information I have about you, not less. — Possibility
I’m not arguing against the implication that ‘other people’ aren’t ‘real’ as such, because I don’t think it’s as important as you might think. I’m arguing that what IS ‘real’ with regard to the notion of ‘other people’ is merely evidence or measurements of their existence in potentiality: ‘other people’ exist and are useful (different to convenient) in this non-real, non-verifiable, conceptual or fictional structure in terms of how we interact with the world.
Real does not necessarily determine existence. This is outdated thinking. Energy and other people are far more complex than mere measurement/observation would suggest. Recognising this enables us to manage our uncertainty and prediction error. — Possibility
Nor am I saying that you presume solipsism, but that it is a consequence of the presumed primacy of experience. — Banno
When you take first-person phenomena - observation - as your starting point, including others becomes problematic, as it seems you have found.
But instead, if one starts with the world as a collaborative construction from its contents, that there are other folk is not problematic.
So i'm suggesting that a reliance on phenomenology leads to solipsism. — Banno
Yes. We are all in this story together. — T Clark
To say that other people is a useful fiction is not to say others or the self (since we are all in that fictive sense other people) are not real, and is no different than saying the self or any identity is a useful fiction; so what's the problem? — Janus
