* From then on we enter the realm of inference. We proceed to the **assumption ***
that an unknown factor causes the pain and** in our minds** we construct a scheme of reality which we call “matter”.
Solipsism is an abstract concept but our subjective reality is the most basic reality of all. Do you reduce our pain to electrical impulses in the brain? Or does it exist in its own right?
I have no idea what “exist in its own right” means. Can you tell me what it means to “exist in its own right”? I can tell you what it means to have electrical impulses in your brain.
The evidence is our stream of consciousness: qualia which cannot be explained in physical terms.
Explained in terms of
what? Explained as to how they are
immaterial? I’m lost as to what criteria you are using for “exists”, and “explains” here. Materialism I think is clear on its semantics there. A perception of our mind as being “disembodied” does not mean our mind is disembodied, for example, and we can explain this as an artifact of cognition, a helpful bit of illusory abstraction that aids is thinking about the self.
But that notwithstanding, what kid of explanation are you looking for? Maybe an example from another area of knowledge would help me.
You are insisting on physical evidence of an immaterial mind as if our primary datum is physical reality, as if our starting point is matter.
Well, we can agree that matter exists, and in that sense, it
is a starting point. A flame on your bare flesh is as real to you as it is to me. That is a great, common starting point, and in that sense, the most mystical Catholic is an unshakable materialist.
So we start from the common affirmation of the reality of reality, of the “truth” of the flame burning our hand, forcing us to withdraw it. Now, we suppose some other mode of apprehension may be possible. You suggest “immaterial reality”. What is the “hand over lighter test” for “immaterial reality”?
Without some grounds for that, I don’t need to say physical reality is “primary” or “complete”, but rather it’s just the only framework that invests objective meaning in the term. That is, the flame is an equal opportunity burner; it burns my hand as badly as your hand. We share that common reality. It’s objective, not dependent on either of our wishes or desires. But what would establish your “immaterial reality” along the same lines? What distinguishes it from delusion?
But it is not! Our stream of consciousness is our primary datum. I could equally well ask you for mental evidence that matter exists. What answer would you give?
Give me your hand while I pull out my cigarette lighter.
How would we falsify the idea of a material object?
Keep your hand in the flame for a minute or so. Run out into high speed traffic. That would be a strong repudiation of the materiality of the extramental world.
All we know is that damage to the brain affects the function of the brain - which is a material object. You are assuming that the mind has a material basis and originates in the brain. How would you prove that is the case?
That’s what the evidence shows. You destroy the brain, the activity of the mind stops. You engage the mind, the electrical patterns dance, and in specific areas (language here, visual pattern matching there, etc.) You mess with a scalpel in the brain, and the mind has all sorts of funky things happen to it in real time. You damage your brain in certain parts and ways, your mind changes. This is how reasoning works about the real world.
“interactions” is the key word. Correlation does not entail causality. Physical events do not destroy intangible realities like truth and justice. So why should the intangible mind depend on physical events?
A very good question. I don’t see that ‘intangible’ adds anything but confusion or superfluity to the conversation at all. Justice is a distributed brain pattern, the ensemble of related brain states in all those who entertain the concept in their brains, and encoded in physical matter as symbols that can (re)construct those same concepts by the reader/interpreter. So what do we need “intangible” for, again?
By direct knowledge - as every single one of us does now. How do we know we exist? Not by observing our bodies!
Well, that’s not the only, but that’s a perfectly sufficient means of establishing that.
You cannot escape from your physicalist criteria which are deeply embedded in your interpretation of reality. It is ironic that truth itself is an intangible reality.
How so? It’s a concept, like “justice” above. Are you familiar with how materialists explain concepts, abstract or no?
Logical positivism was abandoned precisely because of the absurdity of the verification principle. The falsification principle is in precisely the same category…
Falsification is not verification. Falsifiability is a counter
to positivism, not a part of it. And falsifiability isn’t axiomatic epistemically, but methodological in separating out meaningful statements about the real world in a practical way from metaphysical propositions that are not.
But in any case, you didn’t answer my question. It’s fine to say “I can’t”, but how would you falsify (not verify, that’s a totally different enterprise!!!) the ideas you are advancing here about immaterial mind. If that idea was bogus, is there any way you would be able to know?
