#569 · Tom Nassis, about 2 months ago@nick-willmott, you objected to "a brain is a computer." Would you also object to "a mind (a person) is a program?" Why or why not?
Think we're going to get bogged down in unclear relationships to tackle this sorry...
If anything that processes information is a computer, do all computers have programs?
#567 · Tom Nassis, about 2 months agoNick, I think your criticisms are indirectly addressing my concerns. Would you say the framing of "The brain is a computer" does more to obscure and mislead than to illuminate?
We can invoke the word "computer" to say that the brain processes information.
But if that's all we're saying, then I'd say the word "computer" brings so much irrelevant baggage that it might be counterproductive.
Is this why you object to using the word "computer?"
I'm not objecting to the word computer per se, I just don't think a deflationary sense of the word is of any interest for comparision to the brain. The word could be of use to help illuminate what the brain is (and is not), but the comparison I sense would have to be with something more like a general purpose computer / universal computing device.
#558 · Dennis Hackethal, about 2 months agoYou may consider it banal but is it false?
An OR gate takes two bits of information and transforms them into a single bit of information by following a specific rule. It clearly processes information. And if that’s true for an OR gate, why not for the brain?
You're not understanding me. I'm not trying to argue such things don't process information.
I can't argue against "Is the brain a computer?" + "Anything that processes information is a computer" combination. If we're taking an essentialist definition of the word computer then we should ditch the term and the the title of the page should just be "Does the brain process information?" - which I have no interest in objecting against.
My original attempted criticism was against the statement that anything processing information is a computer. (Taking a deflationary concept of a computer is not what I presumed was meant in the title of the discussion).
Parking the word computer aside, based on the resultant thread, more interesting questions to me are:
1) What is the demarcation between something that processes information and something that does not?
2) What is the demarcation between something that processes information and the human brain?
#513 · Dennis Hackethal, about 2 months agoYes re OR gate.
Re light switches: as I understand it, they either inhibit or permit the flow of electricity. But there’s no information there, let alone processing of information. So the example is flawed, I think.
I'll have to tap out sorry. Possibly talking on different trajectories.
If an OR gate is conceived as a computer then the initial post about the brain being conceived as a computer is a banality / an uninteresting syllogism.
#498 · Dennis Hackethal, about 2 months agoIt is under that definition. Not the kind of computer people traditionally think of when they hear the term, like a laptop or desktop, but it’s a computer nonetheless.
Cool. Not sure I can criticise a syllogism. I can try push the definition ad absurdum...
- A light switch processes information. Therefore, a light switch is a computer.
- An OR gate processes information. Therefore, an OR gate is a computer.
#215 · Dennis Hackethal, 3 months agoAnything that processes information is a computer.
The brain processes information.
Therefore, the brain is a computer.
A ribosome processes information. A ribosome is not a computer.
