In what sense is Descartes's dualism wrong?

Is the mind the same as the body? What is consciousness? Can machines have it?

The kind of possibility I care about is tractability.
The kind of impossibility I are about are metaphysical.

If something is not metaphysically impossible, then it's not impossible.

Sure. It's called a quantum Boltzmann Brain.
Gary Childress wrote: Sun Feb 02, 2020 1:24 am Suppose universes are infinite in number, or whatever physicist believe these days, and that in just one of those infinite universes, I am duplicated.

However, I've heard talk of using quantum entanglement to "teleport" people to distant planets. Apparently, some physicists believe they can perfectly physically replicate a person using quantum entanglement, somehow.
You aren't really addressing my point.

There's still the conceptual issue of whether teleportation is copying you to location B, or moving you from A to B.

If we copy you from A to B, and we don't delete you at . We have effectively cloned you. The world-line of B still has a discontinuity.

"you" and "me" are just a labels. They refer to different things depending on who's using them.

You seem to be struggling with drawing lines in the space-time continuum, and all of your questions are loaded with the pre-supposition that mind and body are separate.

They aren't - they are part of the whole. It we, humans who separate/individuate things (draw the lines) in language. It is we, humans who reduce the whole into parts.

Are an apple and an orange not separate things. We use language to distinguish between them. Are you now saying you don't understand what the terms "you" and "me" refer to? You can't just eliminate something by refusing to refer to it anymore. You can stop talking about it but the thing and the differences are still going to be there.

You don't know what right and wrongs are. You don't know what consciousness is. Do you know what a cat and dog are? All I can conclude is that, unlike me, you're not conscious.

If you copy me from A to B and do delete me then I'm dead, right? My clone would continue life but "I" wouldn't, correct? There was something there that was "me" and it's no longer there when you destroy my physical entity. I would no longer feel anything or experience anything. "I" would be gone. Correct?

My question is, what was that "I" that was there and now it's not? It was something distinct from "you". Yes, it seems to be dependent on the brain for its existence but it's not something that can be seen, touched or experienced by anyone else. And yet it was either there or it wasn't.

You could view them as separate - you could view them as a system.

Your choice.

If we copy you from A to B and delete you at A, then there will be a copy of you at B.

If you want to label A as "dead" and B as "alive" - go ahead and do that. Your choice.

Have you heard of Newton's Flaming Laser sword? Great article in Philosophy Now magazine - you should read it: https://philosophynow.org/issues/46/New ... aser_Sword

What measurements or observations would, in your view, settle the matter?

It's a word. I use to refer to myself. It's self-reference. It's recursion. It's the foundation of computation.

That is all we know about it. If you don't like that answre, you will have to come up with a better one all by yourself.

OK. So you're not conscious. You don't feel pain or see the redness of an apple. I place my hand on a hot stove and I draw it away quickly before cellular damage occurs because it hurts like hell. You place your hand on a hot stove and draw it away quickly because neurons in your brain received signals from your hand which caused muscles to contract, etc, and your arm lifted. Is that correct?

Robots and computers can do the exact same thing: https://en.wikipedia.org/wiki/Interrupt_handler

It's only natural to program your robots with some self-preservation logic - they are expensive, you know?

Temperature sensors triggers alarm.
Invokes interrupt handler for "Protect-from-burny-fire" routine.
Robot removes hand until temperature sensor acknowledges recovery.

In control theory this is called a closed feedback loop.

If you choose to label it as "dead" then it would be "dead".
If you choose not to label it as "dead" then it wouldn't be "dead"

If you choose to draw a distinction between "you" and "your clone" then yes.
If you choose not to draw a distinction between "you" and "your clone" then no.

Your choice.

You are struggling with this "freedom of choice" thing, aren't you? The possibilities are limitless!

Perhaps you want a simpler life? Where all the answers are pre-packaged and gift-wrapped for you?

Perhaps you need an introduction into the Metaphysics of Identity? https://en.wikipedia.org/wiki/Ship_of_Theseus

No kidding? That's what I've been saying. If you feel pain, then you are conscious. You have conscious experience. And, yes. it is true. I can't determine if you are conscious anymore than you can me. There's no way to perform a physical test for consciousness.

I'm finished here as far as I'm concerned.

What a way to miss the point. YOU can't determine if YOU are conscious or not! Because "consciousness" is just a meaningless word!

If I put a lighter to your hand something happens in your head. You move your hand back.

So you've reduced all of what happened in your brain down to the sentence: I felt pain.

Bullshit. How do you know that it was "pain" that you are sensing? How do you know that you didn't sense a "temperature interrupt" routine?
Gary Childress wrote: Sun Feb 02, 2020 3:26 pm There's no way to perform a physical test for consciousness.
Which is precisely why you can't answer the epistemic question "HOW do you know that you are conscious?".

You have no method for determination.
