Anything 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.

It 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.

Yes 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.

You 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?

1) What is the demarcation between something that processes information and something that does not?

See #513. Something that processes information must be given some information (at least one bit) and then follow some rule for what to do with it. Then, optionally, return the result. Like the OR gate, but unlike the light switch.

Or is there something I’m missing?
