No, that was not my intent. What I am playing with how would "internal theater" differ from objective reality.
Which is a futile point when we haven´t yet agreed what it is that we experience. You can at best compare what you feel is „objective reality“ (or how you think it should be) to that which you feel „dream theater“ would be like.
If I – as the devil´s advoctate – say that all we experience is „dream theater“, then I can´t compare „dream theater“ to anything, and certainly not „objective reality“ which doesn´t even exist.
Once again you are putting the cart before the horse, as would a „dream theater“ advocate.
If that internal theater presents things which cannot be altered, then that internal theater would operate as if it were an objective reality, even if totally of my mind.
The definition of „objective reality“ as that which can not be altered appears to be spontaneously made up, based on that which you feel you experience as „objective reality“.
Again: since either „external reality“ and „dream theater“ would be the way our experiences are explained (depending on which premise one works from), under the premise of dream theater there is no such thing as „external reality“ that one could possibly compare it to.
I'm simply considering the fact that I haven’t met anyone who believes they can completely or even predominately control phenomena, no matter where it is found . . .
Whether I can or can not control all or most phenomena would be an interesting discussion of its own. For the time being I will submit that even if I can´t control all phenomena in my dream theater this is not sufficient evidence that it is not dream theater. It would just be dream theater in which not everything is in control of my arbitrary will.
I have noticed that your argument originally was about „the ability to alter reality“, now you have shifted the goalposts towards „the ability to control reality“.
If you have experiences differently, feel free to give me experience and anecdote.
That would be an unparsimonous approach. My reality changes from second to second, and if assuming that it´s my dream theater, this is my product. So I could name billions of things that change in my reality.
The simpler would be for you to give an example of something that doesn´t change in my reality.
And there lies the problem: Since – under the assumption of dream theater – everything I experience (including all changes, developments and alterings) would be product of my mind by virtue of the premise, „dream theater“ is unfalsifiable. Just as the premise „external reality that our mind connects to“ is unfalsifiable.
1. the discovery of one's preconceptions is extremely valuable.
Yes, I have emphasized this a couple of times myself already.
2. I'm not saying I've provided an argument against believing all perception is an internal process, I'm just letting you know that I don't agree that perception is all internal.
That has been clear since your OP.
I have asked you multiple times now, whether you want me to accept that premise for purposes of this discussion, and for whatever reason you haven´t yet given me a clear answer.
Instead you keep arguing against „internal theater“, so I am assuming this is what you want to discuss.
I ask you again and urgently: What do you want to discuss with me at this point?
My approach depends on the answer of this question.
If you want a discussion based on the premise that „external reality“ exists, fine with me.
3. Although you don't believe in truth (in the sense of correspondence theory) but something more based on coherence and consistency, (I haven’t misrepresented you here, correct?)
I´m not sure – bear with me, but I am very cautious when someone paraphrases my views with words and expressions I wouldn´t use.
I don´t believe that we could possibly distinguish „external reality to which our ideas correspond“ from „internal theater without external reality“.
you have introduced an epistemological term that has gained ground in contemporary epistemology . . . warrant. What, for you, defines a warranted belief?
Please keep in mind that I am not a native speaker. It´s easily possible that I have used this term wrongly. From what I know about it it is not a term that is used only in epistemology.
Whatever – let me (in order to avoid a semantics discussion) replace it with the term that I have used previously for the same idea: „I want to use as few preassumptions as possible.“
Yes, I agree that this might be a true . . . I've already started giving it some thought. I understand that objective reality is something you'd rather not assume (in keeping to a more parsimonious approach) and that you also think it cannot be proven. However, you are willing to speculate within the confines of granting this assumption. Is that correct?
Yes, this is correct.

I am just waiting for you to tell me whether this is what you want me (or us) to do.
Once we have agreed that we base this premise upon this assumption, we can discuss the next question: How can we possibly discern, detect or acknowledge „objective external reality“ if all we have is our inner reflection of it, anyways? And, other than in the question („external objective reality vs. dream theater“

I do have an opinion here: We can´t.
If we can't critically think, our presupposition come from our society, i.e. parents, school, etc. this seems pretty obvious, most children believe what they are taught by authority as long as it is somewhat consistent and the critical thinking function comes later. How does this statement about the way children form belief relate to your experiences?
Just for clarification: At this point you are already not only assuming that an external reality exists, but also that we can detect and discern it (else you couldn´t speak of things like parents or society, presuming they exist as you feel they exist).
I haven´t included this into my concession that there is an external reality.
Anyways, in my experience there is a correlation between beliefs of society and beliefs of children. Causality would be hard to determine, though. And even if we could show that a lot of beliefs are conditioned into children societally this would still not allow your conclusion that this is the only way beliefs are acquired by children. In context of this question children like Kaspar Hauser would be an interesting subject to research: Do children who do not grow up in a society acquire beliefs nonetheless? If so (which I am actually convinced of without having studies to support it), your point would be refuted.
Remember, I'm playing with concepts, I feel like you are looking at this like its a syllogistic argument. Take each one on its own and tell me you opposition or approval. The question I am considering is whether these statements are reliable.
I have understood this (and I am assuming that you want to establish these as points to work from). If I am asked to consider those points, I actually don´t see a better way than looking at these points, trying to understand what you mean (which often poses the first problem), and then giving you my opinion to each of them. I don´t seem to understand what else you would expect me to do.
I am more than willing to hear what you are willing to assume . . . for me, because I believe in objective reality, am asking truth statements, but I am also trying to consider them from other perspectives, which from your I am guessing will be whether they are useful . . . right?
When it comes to my reality the question „is this assumption useful“ is indeed the predominant question. However, when it comes to discussion like these, all I can do is
- tell you which of your preassumptions I agree with
- investigate whether your conclusions follow from your preassumptions (regardless whether I agree with them are not)
However, one of my most basic objections (even under the assumption that an „objective external reality exists) is your idea that a subjectively experiencing being like me has access to this objective reality. This is a contradiction in terms. All I perceive, experience is by definition subjective, as soon as I perceive it it becomes my idea of it, and that´s that.
Under the premise of an „external reality“ I think it is reasonable to postulate that we interprete it in the way that is meaningful, useful to us. IOW: every statement about something in this external reality beyond „It is what it is“ is not a statement about how this reality objective is, but about what I want or need it to be. This external reality becomes more than just being „what it is“ by virtue of me giving it meaning.
This was my point earlier in the thread . . . logic can test for consistency, but cannot judge between noetic structures except to expose the inconstancy between basic beliefs (i.e. if a noetic structure has beliefs that lead to an inevitable contradiction)
Seems like this is something we agree upon. Partytime.
Well, when I was reading this, I thought the definition of foundational beliefs as those beliefs believed without deductive or inductive justification.
Agreed. (In which we would have to keep in mind that even those beliefs that can be deduced or induced from them have as little justification as those basic beliefs.)
For a Cartesian, I would, without putting too much thought into it, think a foundational belief would be logic and cognition?
You would have to ask a Cartesian what a Cartesiona thinks.
I personally don´t even seem to understand what „belief in logic and cognition“ means.
I do believe that certain conclusions follow logically from certain premises, and others don´t.
Could you please give me your definition of „cognition“? I can´t seem to find a definition in reference to which the wording „belief in cognition“ makes any sense.
Anyway, you yourself mentioned using as few assumptions as possible . . . I would think an assumption, if it is an assumption you consistently use, could be considered a foundational belief
Would you mind spelling out this assumption you are speaking of in a complete sentence?
„Belief in logic and cognition“ doesn´t seem to tell me what exactly you think I believe about them.
Well, that's one of the things I'm trying to discern. Is there a way to judge between noetic structures. You seem to think that there isn't, which would make sense if we are all locked in our own realties. I'm not sure that lock is there . . . In fact, I entertaining the idea that the belief in that lock is an unaffirmable belief.
I don´t see how it is necessary to assume we are „locked in our own realties“ in order to come to the conclusion that we can´t judge between noetic structures.
I think that e.g. your own submission that all our beliefs are either foundational beliefs (without deductive or inductive justification) or beliefs that we are taught by society or beliefs that are deduced or induced from these two leads necessarily to the conclusion that we can not judge between noetic structures. For that we would have to discuss the justification of foundational beliefs, and this is – by virtue of the very way you have defined them – impossible.
n epistemology, a statement (claim, assertion, proposition) is epistemologically objective if its truth value can be determined intersubjectively by generally-agreed methods or procedures. To say a statement is epistemologically objective is not to say the statement is true; it's just to say we could figure out a public method for determining whether or not the statement is true.
Mm, ok. „Objective“ comes with a lot of different meanings, and the way it is defined here is completely different from your initial idea of an „objective external reality“. „Objective“ and „true“ defined as basically synonyms for „intersubjective“ or „generally agreed upon“ are fine with me. I still would prefer the terms „intersubjective“ and „agreed upon“ over „true“, simply for the purpose of avoiding misunderstandings and conflations with other meanings of „true“.
I myself have proposed „intersubjectivity“ and „agreement“ for useful approaches early and several times in this thread. Searle seems to hold a similar notion.
The word „objective“ has always been used in that definition in science.
I don´t think that in traditional terminology „true“ and „publicly believed to be accurate“ are considered the same, but, oh well, if he insists on that redefinition, no skin off my nose. Language evolves. Words mean what the person using them means by them.
