Evidently you can interpret it as 'yes' or 'no' because people do, as I showed. Arbitrarily announcing that it doesn't does not make you right. The brain activity is physical proof that a conscience thought has been made by the user. It may just be the areas of the brain that they are using to complete the task that light up, but it still provides physical evidence of the physical thought in the first place. And the fact that humans can sometimes make a thought with their subconscious  does not make any difference to an argument concerning the measurement of a conscience thought.

No its not .. It just shows the person thinking. Its an evidence for the existance and activity of a human thought and brain activity itself. Not an actual evidence that shows a human thought. And btw, a human soul has no physical evidence whatsoever but it doesnt mean it doesnt exist.


I'm certain that there is no such thing as a soul, it's just a label we've applied to our conscience. But that's another argument for another day.

The MRI really is showing you that a conscience thought has occurred, that's the thing. You can measure that a thought has occurred by analysing the way the brain is acting. It's perfectly reasonable to say that something exists by the way it affects other things.

It's like trying to detect a sub atomic particle. A sub atomic particle isn't big enough to pick up and hold in your hand, you can't really feel it there. So what we often do is measure the interactions it has.

An easy to relate to example I can think of is the microwave. The microwave is basically a machine for firing high energy photons at your food, and, in the strictest sense, your food is essentially the photon detector. You can't see the photons, you can't feel the photons, but the fact that your food is now cooked is proof that they exist.

I don't really see how measuring brain activity to show thought is any different. I think seeing specific areas of the brain light up when expected as a result of a conscience thought is sufficient proof that a thought has been made. Otherwise you would also have to deny that sub atomic particles have ever been detected (with a few key exceptions of course).
