With "syntactic", do you mean symbolic? We can and do observe values, patterns, and their potentials.
Symbolic, yes. In the formal sense. There is an alphabet of symbols. The alphabet is taken to be at most countably infinite. When the machine encounters a particular symbol, it flips some bits and goes to the next symbol. Given a particular state of the computer and the particular symbol, it's entirely pre-determined what bits it will flip. It's defined by the computation's program.
I'm being picky like that because I can refer to this if you start to get poetic and fanciful about what algorithms are.
I wish to state that I am
not opposed to poetry. I like imagery and intuition. I just want to make sure that when we're talking about algorithms, we're clear on whether we mean that in the technical sense or the poetic. Because once you use words like "patterns and their potential" I get that old woo-woo vibe and I feel that you are leaving the realm of the science of algorithms and drifting into the poetry. And that may be leading you astray in your reasoning.
Your assertion that the brain does not use algorithms because it is sentient is based on what?
Because our minds understand
meaning. They have intensionality, "aboutness." When computers flip bits, that activity is meaningless. Humans impart meaning to the bits. These bits are a discussion forum, those bits are a cat video. That's what the
humans add. If you just looked at the circuitry of the computer you'd just see a long but finite string of bits 1010101010010001001001001... There is no meaning in that, nor in the manipulations of the bits by the program.
In case it's not obvious, this is basically Searle's argument in the Chinese room. So if you and I disagree on that subject, we can agree to disagree. Many people think the room is conscious or self-aware or understands Chinese. I happen to think that's absurd. So now you know my philosophical orientation to all this.
We know that computers (which are not sentient) must use algorithms, in order to execute the processing of information.
Yes.
Programmers write these algorithms, which at the least indicates an understanding of these mathematical functions.
Yes.
The humans impart meaning to the symbols. If I had to put my entire argument into a short sentence, that would be it.
If they work in non-sentient computers (pseudo intelligence), what rule prevents the sentient (intelligent) human brain from using these effective mathematical functions also?
Oh, nothing prevents humans from using effective mathematical functions. For example a long time ago I took a class in number theory. Early in the class they required us to execute the Euclidean algorithm by hand. In that moment my brain caused my body to execute an algorithm!
OF COURSE THAT HAPPENS. Of course PARTS of our brain may be algorithms. Reflexes, say. Doctor taps your knee in just the right post and your knee jumps. That's probably a little subroutine in the nerves that operate the muscles. I'm perfectly happy to stipulate that.
But not ALL brain and mind function can be explained as the execution of algorithms in the brain.
It's "some" versus "all." Are some brain functions algorithmic? Probably. Could we prove that it's at least possible? Sure, just execute the Euclidean algorithm in your head. 8 and 14 in, 2 out. Boom, I'm a digital computer that can execute a 2000 year old algorithm. Substrate independence. Euclid and I can execute the exact same algorithm in our respective brains.
But not ALL brain function is an algorithm. And the fact that algorithms are substrate independent does NOT prove that mind is. I saw Tegmark make that argument in an article recently. He's totally and completely and utterly wrong.
After all is said and done and all semantics aside, the human brain is a biological computer,
It's biological, agreed.
When you say biological computer, what do you mean by that? If by computer you mean a digital computer according to the abstract theory of Turing and the contemporary practice of hardware and software engineering, then
there is not a shred of evidence that the brain works this way. There is no cpu, there's no ram, there's no instruction set, there's no clock, there's no program. None of these things.
So I must ask you if you would be willing to clarify EXACTLY what you mean by that remark? Do you mean to say that a biological computer is different than a digital computer? If so then how about using a different word. Call it the
biological foozle and I will have not a single objection to write about. I'll have nothing to post. I'll be done here.
But if you call it a computer and you mean to invoke the science of modern digital computing, I simply must push back as strenuously as I can, because you are making an assumption utterly without evidence.
but it's function is at the same scale of a computer, i.e. at nano scale. And in the end it is just processing values just like a non- sentient computer.
The brain? Processing values? If by processing you mean computing then you have no evidence. It's the same problem as in your previous paragraph. You are using the word "processing" ambiguously. You want it to mean both "whatever it is the brain does," and also "what a digital computer does." It's a subtle switch in language. If you get very clear about what you mean by processing, your argument fails.
Again. The brain ultimately processes its gooey bits just like a non-sentient
foozle. If you'll just stop calling things computers when you have provided no evidence that they are computers, I'll stop objecting. And honestly I think I'm just being tiresome now. I've pretty much made all the points I can make and if we agree to disagree so be it. But I think you are confusing yourself by overloading words like computer and process and algorithm so that they have both poetic and allegorical meanings as well as technical meanings, and by that ambiguity you are making an argument that fails once the ambiguity is identified.
That's how I see it anyway!!
But, unlike computers, the brain also functions at the bio-chemical level, which I suspect is responsible for "emotions" such as pain, pleasure, desire. (i.e. opioidaddiction).
So those parts are NOT algorithmic. Well then we're in agreement. Is that correct? If only SOME parts of our minds are algorithmic, I have no objection to that thesis at all. As long as you acknowledge that there's also something else going on, something that's not algorithmic.
Ever seen an addicted computer?
Haha I've seen a computer addict! In the mirror I think.
That the bio-chemical difference. And perhaps this phenomenon is also produced by a form of chemical algorithm.
As Ronald Reagan said to Jimmy Carter during their 1980 debate:
There you go again.
https://en.wikipedia.org/wiki/There_you_go_again
Please, call it a chemical
foozle and I'll say, Yes, I agree with you! Parts of the mind are algorithms and parts are foozle. I agree with that!
But when you want to say that some kind of phenomenon that is clearly NOT computational, can still be called a computation or an algorithm,
you are making an invalid argument by using the same word in two different senses.
I am not saying that there is no difference between a brain and a computer. I am saying that fundamentally the calculating brain processes (best guesses) can be compared to what we call "algorithms" in computers.
Compared to. So after all this time you are not actually stating a claim. You're only making a metaphor? If you'd said that up front I'd have never raised a peep. You serious? You were only making a metaphor after all? Shall I compare thee to a summer's day? Thou art more lovely and more temperate.
You don't actually MEAN the brain operates via algorithm, but only that you are making a metaphor? Please clarify this point, you will save me a lot of typing going forward.
I am familiar with the term "foozle" and it has nothing to do with a bungling brain function,
You must know something I don't. I was using the word as a completely meaningless word that could stand for anything. If you know some specific meaning for it, that was not my intention. It's not bad, it is? Am I out of touch? Sorry about that.
Call it "woo-stuff," the mysterious whatever that minds do that man-made machines may or may not be able to do or may someday do. So whenever you want to talk about "emotional processing" in the brain that's sort of like some
biological woo-stuff, I'll reply only to express my enthusiastic agreement with your point!
but I do understand the concept of a variable (fuzzy) algorithm, depending on subtle differences of the input information..
Word salad. Fuzzy algorithms? Look, I can write a program that goes:
if today is tuesday take out the trash
else lay in bed.
That's a program that does something completely different depending on "subtle differences of the input information," like what day it is.
