"If you think about your own vision, you can see millions of pixels constantly, you are aware of the full picture, but a computer can't do that, the cpu can only know about 32 or 64 pixels, eventually multiplied by number of kernels, but it see them as single bit's so in reality the can't be conscious of a full picture, not even of the full color at a single pixel.



He is making the same mistake Searle did regarding the Chinese room. He is conflating what the CPU can see at one time (analogous to rule follower in Chinese room) with what the program can know. Consider the program of a neural network: it can be processed by a sequentially operating CPU processing one connection at a time, but the simulated network itself can see any arbitrary number of inputs at once.

How do he propose OCR software can recognize letters if it can only see a single pixel at a time?

Who says OCR software can recognize letters? All that it needs to do is execute some algorithm sequentially and blindly against a table of expected values. There need not be any recognition of the character as a character at at all, let alone any "seeing". A program could convert a Word document into an input file for an OCR program without there ever being any optical activity - no camera, no screen caps, no monitor or printer at all. Completely in the dark, the bits of the Word file could be converted into the bits of an emulated optical scan, and presto, invisible optics.

Searle wasn't wrong. The whole point of the Chinese Room is to point out that computation is a disconnected, anesthetic function which is accomplished with no need for understanding of larger contexts.

Searle might be right on non-comp, but his argument has been shown invalid by many.

I'm surprised that you would try to pass that off as truth Bruno. You have so much tolerance for doubt and uncertainty, yet you claim that it "has been shown invalid". In whose opinion?

It is not an opinion, it is a fact that you can verify if patient enough. The refutation is already in Dennet and Hofstadter "Mind's I " book. Searle concludes that the man in the room is not understanding chinese, and that is right, but that can not refute comp, as the man in the room plays the role of a CPU, and not of the high level program on which the consciousness of the chinese guy supervene. It is a simple confusion of level.




This page http://plato.stanford.edu/entries/chinese-room/ is quite thorough, and lists the most well known Replies, yet it concludes:

"There continues to be significant disagreement about what processes create meaning, understanding, and consciousness, as well as what can be proven a priori by thought experiments."

Thought experience are like proofs in math. Some are valid, some are not valid, some are fatally not valid, some can be corrected or made more precise. The debate often focuse on the truth of comp and non- comp, and that involves sometimes opinion. I don't really play that game.




The replies listed are not at all impressive to me, and are all really variations on the same sophistry. Obviously there is a difference between understanding a conversation and simply copying a conversation in another language. There is a difference between painting a masterpiece and doing a paint by numbers or spraypainting through a stencil. This is what computers and machines are for - to free us from having to work and think ourselves. If the machine had to think and feel that it was working like a person does, then it would want servants also. Machines don't want servants though, because they don't know that they are working, and they function without having to think or exert effort.

And this is begging the question.
