@IMST: Uhm, i probably expressed myself to cryptical. My argument is precisely that you can *only* rely on your senses (or rather your observation, because there arguably may be observation that do not come through what we classically know as senses).
And how is does that necessarily lead to solipsism? As I said, it might that more than one person share the same fundamental consciousness and this is knowable, even if we right now can not be totally sure that others have subjective experience.
If it was in principle unknowable if other people have subjective experience I think this would lead indeed to solipsism. If we could never directly know whether other people have subjective experience, in effect "other people have subjective experience" and "other people do not have subjective experience" would be indistinguishable and thus assuming one or the other would be an empty belief. We could then only make (useful) theories about the *behaviour* of persons.
@Lowpro: No, I'm sincere. I can understand why one would hold such a belief (sometimes empty beliefs sound "good" to your mind) - actually I myself believed in materialism for quite a long time - but I can not understand what the meaning of this belief actually is.
What does it mean *for me* to make a statement that is "true" independent of me? I can only ever know truth in the context of myself. Do you feel that is different for you? If yes, please give me an example.
The rest of your post are mainly assertions that I can not follow so I really can't answer to them, sorry. I don't get how arrive at your odds or why biochemistry does not allow for consciousness to be fundamental.
Personally I think it's likely that subjective experience corresponds to computations, that is, it is not substrate dependent. For all I know my personality might not be dependent on biochemistry (e.g. minduploading might be possible) and this applies even more for consciousness (because it is more general than personality - personality is a form of consciousness).
@Ichneumonwasp: I agree we can only guess about what really exists apart from what we can know. But I would formulate it more strongly: All statements about what really exists apart from what we can know are empty. I have yet to discover something suggesting the contrary.
For *me* what I know is what "really" exists *for me*. I have no way of making coherent statements that are outside of this. So, I don't think there is a gap between ontology and epistemology. What we can directly know is all what surely is for us.
And no, time and energy are not the basis of materialism. We can threat time and energy as things we can measure, without jumping to (in my mind incoherent) conlusions about what this means *really* exists.
This seems like a really common confusion. It's like saying morality sounds like the basis of christian religion, therefore it is likely to be true. It just doesn't follow.
Seems to be the nature of philosophy-- More an exercise in the precise use of language than a means by which we can achieve knowledge-- Language can certainly be very moving.
Yes, this is why I don't like philosophy as commonly practiced. But I hope maybe it is possible to have a conversation that does not end in endless discussion about what is the right way to phrase abstract ideas most precisely. I don't think we can phrase most fundamental issues precisely, because they are simply beyond language.
Maybe I'm deluding myself into thinking it is possible to have fruitful conversations about philosophical issues without falling into this trap and it is, when it comes down to it, an hopeless endavour.
Something that feels right in your gut-- Very few will argue with your gut, as long as you're up front about it. Just don't expect folks to believe that what you're saying is true based on nothing other than the strength of you personal conviction.
Right, but this is not my point. I want people to know for themselves what is true and asking questions or explaining what it is that leads me to this conclusion might help. I did not stating they should follow my belief just because I believe.
Actually I despise this kind of thinking, it leads to very disastrous consequences and we all are susceptible to it. Myself included.
Even when I thought I was thinking oh so freely I was dead wrong and in fact just adopted other people's beliefs (e.g. regarding materialism or even worse politics - it seems hard to belief for me that I once believed in the goodness / necessity of the state or even, to some extent, state socialism).
"Something independent of me" means something that exists regardless of whether I exist.
Exactly!
Again, it's axiomatic. A mind-independent, consistent, probabilistically predictable universe seems to exist. There is no reason to assume that it doesn't.
Well, in my humble opinion the belief into mind-independence is simply a belief you copied, but is actually empty (and thus probably just serves to confuse you).
It is very understandably to belief this. We want to make statements that are independent on our *particular state* of mind, so to assume they are independent of our generalized mind (=consciousness="I am"-ness) seems like a small step. But it is not.
So my question to you is, what is the reason that makes you believe that the universe is mind-independent when you actually always use your mind (in a general sense) by observing it?
I can not prove it to you and I can not give you a reason to assume it isn't mind independent, because an empty belief can logically believed, without this being demonstrably wrong (just like you could write 1+1=0+0+0+0+0+0+0+2), but I think it is important psychologically to not hold empty beliefs that we take to be meaningful.
Of course I can believe that there are living invisible pink unicorns on the moon, and arguably no one can show me that I'm strictly wrong about it. But making it the centre of your worldview will most probably confuse you.
For instance? (bold mine--)
"The universe exists independently of me". Very clearly we cannot observe this directly. And to infer it indirectly seems to be totally arbitrary to me. What is it that justifies this step?
This sounds like a bid for immortality, though I may be misreading you. I don't like the idea that I will someday cease to exist either. You speak of merging identities to the point of a total personality change. Were that to happen, how would the result be "you" in any meaningful way? Which is neither here nor there, other than as an exercise in rhetoric. Once your brain dies, you (the personality) are gone. The universe, however, will keep clicking right along.
I indeed believe in immortality.
I clearly will never find my consciousness gone (retrospectively there might be a meaning to this, but of course if we die in a final way there will be no retrospection). Therefore I must always find it to be there. And this translates into: "I am immortal". I just don't see any alternative.
I reckon that if I "add" something to my personality (for example another personality) it is preserved from my point of view, even if somebody else would assert I changed beyond recognition.
We only know that if the brain dies, the presonality dies relative to the people around you (some would argue this is not universally true and some people can have contact with dead ones; there seems to be some evidence of this, but I'm not going to argue it is extremely convincing).
What really happens to your personality is an open problem.
But I believe my personality can be more adequately described as an informational pattern than as a physical state of my brain (after all my brain changes dramatically during my life, and according to quantum mechanics it's questionable if there really is something solid that is my brain). I reckon informational pattern can't vanish, so they can only be relatively forgotten. Some day someone might recover the informational pattern that corresponds to your personality and you feel being resurrected.
In your OP you said:
"We also could conclude that we don’t (or cannot) know what the basis of reality is."
Again, I could be misreading you, but I get the feeling that you actually adhere to an ontological position that could be summed up as "The basis of reality is mind."
Yep, my conlusion is that the basis of my reality can be known to be consciousness (I like this term better than mind, because I think it's more precise).
But if someone can't follow (or doesn't share) my reasoning of course saying "I don't know" is fine, too, , that's why I included it. It's alot better than believing something empty, but taking it to be something profound.
All well and good-- Just don't expect folks to believe it just because you really, really, think it's true.
I don't. I only want encourage deep introspection instead of just pushing words around or searching for some unfindable (in regard to this topic) objective truth, that's why I am appealing to subjective truth (but yours not mine!).
I don't know if I succeed with that, though.
