Prove it…Does the brain exist? Lay out your proof.

I’d have a MRI or catscan made of my head and mail you the photos if you’d accept that as proof?

No. I would accept that as evidence, not as proof. The reason you cannot prove it is that you cannot prove your senses are providing you with correct information. And even if they are, there can be no proof you are interpreting the information correctly. We ususally verify physical facts by consensus. If I say I see a red ball and you say you see a red ball, then we will likely agree that the red ball exists, but the doesn’t mean it does. It just means we agree it does. Now what I understand as a ball may be different then what you understand a ball is, and if you hopped into my brain, the red I am seeing you may describe as blue, who knows. In this respect, it doesn’t matter if we’re right, it only matters if we agree.
It could all be in a “mind” and you only have a delusion of having a body or a physical presence. It’s a study in epistemology, i.e. what can be known, not thought or inferred. See DesCartes, he started it…

Hell, and if some of the more recent quantum theories are right, physical matter is an illusion as it is basically, empty space and energy, nothing ‘physical’ about it.[/quote]
Semantics. In a court of law you’d seek evidence to prove a crime was committed.
An MRI, or opening up my skull is sufficient evidence to prove that my brain exists.
It does not matter if matter is condensed energy. It does not matter if perception is a mirage of the brain in order to be able to function.
Within our sphere of existence, perception is all there is.

In this realm, the semantics are an important distinction. This is not a court of law where your proof has to be reasonable. In this court, it has to be absolute. It is reasonable to based on your evidence, that your brain is a real entity…But it’s a correlational inference. Not a deductive truth.
Your last sentence is the most important, yes it’s all we have to know the physical world. Perception is malleable, perception can be wrong and often is… [/quote]
That i have a brain is not a deductive truth? How about mindaltering drugs? A lobotomy that changes a person? A braintumor that renders a person mute, or changes short-term memory?
How can you even claim the existence of a brain can not be proven deductively without a brain?
Have you read the link i posted a page back? Do you think those scientists believe the brain is not a proven entity?
Perception is often wrong or incomplete, that is true. That does not mean that the simple fact that without the brain we wouldn’t have any kind of perception is therefore unproveable, or that the existence of the brain can’t be proven.
You are nothing without your brain. Literally.
