Yes! And this is the point. When I say “two” and you say “two” there is no reason to assume that the same neurons fire in our different brains. Moreover, when I say “two” and a German says “zwei”, we definitely have different neurons firing. It does not matter, as long as we agree that we refer to the same abstract concept. But that does not eliminate the fact that in both cases there are physical neurons firing.The unclearness may have come from the fact that you used the equality of two mathematically identical objects to make a point about two numerically distinct physical objects that do not share all of each other’s features.
Let’s examine a human-robot exchange. In the robot’s brain there are electronic circuits, not neurons. There is a difference between the physical methods of processing the information. But the same kind of “agreement” holds here, too. Words, propositions have no “intrinsic meanings”. We assign them mutually agreeable meanings in a communication channel. If we want to, we can create a “private” language, just you and I. We can agree that in our private conversation when we say the word “two”, we actually mean “three”, and vice versa. So the very same neuron firings will carry one specific meaning when we talk to each other, and a different meaning when we talk to others. But that does not invalidate that those pesky neurons keep firing.
Just like the German and you saying “zwei” and “two”. There is no mental difference, only different physical representations of it. Just like (1 = .999999…)I think you are missing the point of the thought experiment. I am a human; I have intentional and qualitative thoughts. The argument is that there could be a zombie with physical states identical to mine without intentional and qualitative thoughts. Obviously they cannot be told apart - that’s the point. The point is that if there were a mental difference, the physical facts wouldn’t tell you about it.
Certainly. And it has nothing to do with the “infrastructure”.You seem to be reifying the problem of other minds. But so long as other humans are of the same kind that I am, it seems reasonable to suppose that they have minds.
Those “other considerations” account for nothing. You still refuse to consider that the physical infrastructure is inseparable from its activity. And those – together – account for the mind. Just like you can have the same source code, compile it onto two very different computer architectures, run them on two different computers and get the same result. The “hardware” is different, just like a human and an android or a robot, the “software” (the object code or executable) is different, but the source code and the result are the same.But since other considerations inform me that the physical facts alone can’t account for their minds, I am unjustified in thinking that a purely physical object that I create - an android, say - likewise has a mind.
You said it right here:From which part of “whether or not we can tell the difference” did you get “now we can tell the difference”?
And I asked: “on what grounds do you call one of them a “con man”? Why do you “care” if there is nothing to “care about”?Of course we care, whether or not we can tell the difference. It’s quite useful to know whether you’re talking to a conman or an honest salesman. Maybe the conman’s a good enough actor that we can’t tell. So much the worse for us, because regardless of the functional equivalence, the conman and the honest salesman have very different mental lives!
No, there is not. Just like you cannot tell if one of salesmen is a con man.There is a way to tell which was the original.
