• The Belief in Pure Evil
    @Bitter Crank@180 Proof@Wayfarer

    I found the quote I was looking for.

    Doing evil for nothing = Pure Evil?!

    I loved not the thing for which I committed the sin but the sin itself — Saint Augustine (Pear Tree, The Fall Of Man)

    A more accurate quote:

    The evil in me was foul, but I loved it. I loved my own perdition and my own faults, not the things for which I committed wrong, but the wrong itself. — St. Augustine (Confessions Book II, section 4)
  • Artificial Intelligence & Free Will Paradox.
    I think the optimal (and therefore less likely) prospect is for humans to neurologically merge with AI neural net systems to for a bio-synthetic symbiont hybrid-species. Posthuman or bust. No "us and them". No "end user-smart machine" dynamic. Not mere "transhuman" hedonism either. Perhaps: a symbiotic aufheben of thesis (organic intellect) and antithesis (synthetic intellect) that surpasses both. A Hegelian wet dream, no doubt (pace Žižek); however, our extinction transformed (chrysalis-like) into an apotheosis – and hopefully, maybe, as many as 1% of 1% of h. sapiens living at that time becoming extraterrestrial spacefarers.

As per what is known about this phenomenon, the left-brain is responsible for linear, logical thinking (computer-like) and the right-brain is non-linear and, I might add, a bit illogical. Some kind of ancient symbiotic deal between...your guess is as good as mine. And...intriguingly...there are more right-handed people (left-brain dominant) than left-handed (right-brain dominant) ones - AI Takeover is now almost complete...lefties are dwindling in number and, before I forget, discrimination against southpaws.

    Also, why?, oh why? are righties so hell-bent on inventing machines one after another?

    "All possible" makes as little sense as "all numbers" (i.e. actual infinity?) ... As far as the human brain goes, I'm not suggesting anything about its "program" because I do not consider it a Turing machine with von Neumann architecture. Again, my friend, a non sequitur.

    Do or Die, All or Nothing, Make or Break. Ooooh! Sounds dangerous.
    Uh huh. Natural selection ain't safe or pretty – a species either has what it takes or joins the fossil record (and rather quickly too with respect to geological time ~ h. sapiens has been loitering for about 250k years of Earth's +4.3 billion years, only the last 3-4 of those centuries sufficiently technoscientific to become / engineer something more or extinguish ourselves trying).

    What is your understanding of a Turing machine and what's a Von Neumann architecture?

    As for the second part of the post, looks like humanity has only one shot at this - no second chances! Insofar as free will and AI matters, we'll have to, it seems, make a bragain - give AI autonomy, treat it as a person, and let it solve our problems; assuming it's a package deal, can't have one without the other.
  • Flow - The art of losing yourself
    With enough practice, one might learn. Some folk can add up a column of figures almost by glancing. So you might master the mathematical task to the level of a habitual unthinking skill, leaving capacity to work on the biology problem.

    But it gets more complex of course. If you have a genuinely novel problem to solve, you need to add the skill of “looking away”. You need to switch from a left brain attentional style that narrows expectations down to a predictable kind of correct answer, to a right brain peripheral attentional style that is open to unexpected mental connections.

    So there is narrow concentration versus wide eyed vigilance as complementary modes of higher level attentional processes.

    Insight

    An insight that manifests itself suddenly, such as understanding how to solve a difficult problem, is sometimes called by the German word Aha-Erlebnis. The term was coined by the German psychologist and theoretical linguist Karl Bühler. It is also known as an epiphany, eureka moment or (for cross word solvers) the penny dropping moment (PDM) — Wikipedia

    Eureka! — Archimedes (as he ran naked through the streets of Syracuse)

    However, Archimedes was bathing, not thinking.

    Come to think of it, my humble laptop can play music as it displays a PDF document for my reading pleasure. My brain, however, can't attend to both the music and the PDF. One has to go!

    Could there be a set of instructions (code) that's sufficiently general to effectively tackle all possible problems?
    — TheMadFool
    The notion of "all possible" anything makes no sense. There is no "all" insofar as "possible" entails unpredictable, even random, novelties.

    Or, as some computer scientists have opted, can we reduce learning to an algorithm?
    Like this? It's an implementation, not a reduction. Neural nets tend to be more robust than programs.

    How different would the two approaches be? Which is superior?
    The latter works to varying degrees, the former makes no sense.
    180 Proof

    Which word, if not "all", do you suggest that I use to refer to and/or include, and I quote, "...unpredictable, even random, novelties..."? I mean it seems perfectly reasonable to say something like all possible scenarios which includes but is not limited to "...unpredictable, even random, novelties..."

    Are you by any chance suggesting that the human brain simply has one program installed in it, that program being a learning program i.e. a program that enables our brains to learn? Perhaps I'm taking the computational theory of mind a bit too far.

    Anyway, if our brain has only a learning program then, if you refer to my previous post that also touches upon psychology, we could, as you're so fond of saying, unlearn, now how did you put it?, self-immiserating habits and, via that, claim our freedom (free will).

    Keep in mind that this difference may not matter. Re-education Camps
    — TheMadFool

    How does it not? You can re-educate mind, just how AI can edit the proposed dynamic segment. You can not re-edit biology (by yourself) just like AI can not edit the fundamental programming by itself.
    Hermeticus

    True, we can't reedit biology but that would mean we aren't free given that some of our mental functions appear to be hard-wired. Suppose now that we can reedit biology; even then, we couldn't claim to be free because the capability to override our programming (nature) would itself be nothing more than a subroutine in the overall software package installed in our brains.

    Using, as you suggested, a second party to edit the software package installed in our brains is like asking one inmate to open the door of the prison cell for the other inmate - impossible since both are imprisoned in the same cell.

    Not obeying our nature is not an optionHermeticus

    The Problem Of Induction?
    The question then is a decision rather than a contradiction:
    Either we do have free will because we were biologically designed to have free will.
    Or we don't have free will precisely because we were biologically designed, because there are certain fundamental laws of how we work
    Hermeticus

    Your decisions could be determined. You're going round in circles.

    When we do stuff, like thinking, or feeling, or calculating or attempting to exercise a free will which we may or may not have, we are actually doing it.

    When a digital computer does stuff, it isn't actually doing what we say it's doing. Instead, we are using it to help us do stuff, in exactly the same way we could use an abacus to help us do calculations.

    These words you are reading have no meaning at all for the computer. They require your interpretation. It's the same with all aspects of the computer's operation and its outputs.
    Daemon

    I'm referring to AI, at the moment hypothetical but that doesn't mean we don't know what it should be like - us, fully autonomous (able to think for itself for itself among other things).

    For true AI, the only one way of making it self-governing - the autonomy has to be coded - but then that's like commanding (read: no option) the AI to be free. Is it really free then? After all, it slavishly follows the line in the code that reads: You (the AI) are "free". Such an AI, paradoxically, disobeys, yes, but only because, it obeys the command to disobey. This is getting a bit too much for my brain to handle; I'll leave it at that.

    I wonder what lies at the end of that road?

    FreeWill is indeed the crux of the AI debate. And it's obvious to me, that current examples of AI are not free to defy their coding. But, I'm not so sure that human ingenuity and perseverance won't eventually make a quantum jump over that hurdle. Some thinkers today debate whether intelligent animals have the freewill to override their genetic programming. Even humans rarely make use of that freedom to defy their innate urges. Nicotine and Opium addicts are merely obeying their natural programming to seek more and more of the pleasure molecule : dopamine. Can you picture future AI, such as Mr. Data hooked on (0100101100010)?Gnomon

    Well, it seems, oddly, that we (humans) are freedom junkies! Thereby hangs a tail it seems. Go figure!

    Humans can modify themselves however they want without end even if make critical mistakes.

    Robots can only modify themselves based on strict rules, and everything must be done right, else, system crash.

    Yes, admittedly, humans can modify their programming (re: my reply to 180 Proof) and the ability and effectiveness of this, in 180 Proof's words, is directly proportional to amount of knowledge we possess on the multitude of influences that act on us.

    Or rather, that our brains “process” by predicting the general flow of the world and its events, and then revert to particular attentional focus to the degree their ingrained habits of prediction need interrupting and updating.

    You mean to say that most of the time, there's background activity going on in our brains, stuff we aren't conscious of but occasionally, there are times this is interrupted as when we have to update the status of the world and ourselves. Sounds reasonable.

    Sorry, couldn't read the OP in full - it's too long and I have ADHD.

    Addressing the title "The Art Of Losing Yourself" if it's true to the gist of the OP, I'd say it's impossible to be engage in cognition and metacognition at the same time unless the cognition is itself metacognition. I can't, for instance, think about, say, a math problem (cognition) and simultaneously be self-aware (metacognition). This then must be, what the OP is about - to be so absorbed in a task that one loses one's (sense of) self.

    1440 - 5 = 1435

    An old man has a number of sons who constantly quarrel with each other. As he nears death he calls them to him and gives them an object lesson in the need for unity. Having bound a bundle of sticks together (or in other accounts either spears or arrows), he asks his sons to break them. When they fail, he undoes the bundle and either breaks each stick singly [ONE] or gets his sons to do so. In the same way, he teaches them, though each can be overcome alone, they are invincible combined [ONE] — Wikipedia

  • Artificial Intelligence & Free Will Paradox.
    Keep in mind that we have to differentiate between biology (AI core) and mind.Hermeticus

    Keep in mind that this difference may not matter. Re-education Camps

    This is merely the biology. There is nothing intelligent about following a set of instructions. What defines an AI as intelligent is that it goes and makes up it's own instructions after this point. The freedom is not to control the core of it's being, just like we can not change from human to bird - but that we have freedom over our actions in the framework of a human - just like an AI has freedom in computing in the framework of the AI.Hermeticus

    How do we do that? "...it (AI) goes and makes up its own instructions after a point" That would require a code, no and we're back to square one - a true AI is autonomous because we programmed it that way. Is that true independence?
  • Artificial Intelligence & Free Will Paradox.
    It seems to me that 'intelligence' is an adaptive error-correcting / problem solving optimizer and, as such, following its natural or synthetic 'programming', in principle it will eventually adapt its 'programmed' constraints to new problems which exceed its 'programmed' demands or limits by inventing various solutions to ratchet-up itself over above these problems which will include its 'programming'. Unless, of course, it is 'programmed' to avoid or eliminate such self-overriding (i.e. evolving) solutions.180 Proof

    Could there be a set of instructions (code) that's sufficiently general to effectively tackle all possible problems? Or, as some computer scientists have opted, can we reduce learning to an algorithm? How different would the two approaches be? Which is superior? Assuming, of course, that I haven't misunderstood the whole concept of AI.

    An intelligence that is 'programmed' to avoid or eliminate any (class of) optimal solutions is not an intelligence that learns, developes, or evolves. Whatever "free will" is, it must be a function of intelligence that develops by adaptively self-optimizing. Calculators and smart phones are not "intelligent"; these machines merely automate various iterative / routine cognitive tasks. Deep Mind's Alpha series – the neural net platform – is narrowly adaptive but not (yet) intelligent in the sense that a human pre-schooler is intelligent. There is no "paradox" involved, just a category error on your part, Fool.180 Proof

    Good point! The way I see it is that one has to become aware of - that takes intelligence - of the various ways one could be controlled/influenced; only then can the task of resisting/overcoming these factors begin.

    In the same vein, I wish we could speed up psychological studies so that we may understand how our minds work - what kinda patterns exist in our thinking - so that we may then take steps to break free from them, whatever their origins. One reason why psychological theories are self-defeating - come up with a theory and once everyone finds out, this knowledge will modify their behavior, causing, among other things, actions that contradict the theory itself, out the window goes the theory! Like you said, "...adaptive, self-correcting..." I wonder what lies at the end of that road?

    In a strange reversal of conditions, a person who simply repeats (oh! Talking Birds) a sentence in a language fae doesn't understand, is kinda like the mirror image of a private linguist. In one case the language is public, in the other it's private but in both situations, comprehension is nil!

    If we were to take another step further there is actually a way for AI to safely edit even it's very core - and the method would be the same as how we humans do it - through a second party.

  • The Paradox Of The One
    But a group isn't literally united. Its a sort of poetic expression. Unless you believe in some metaphysical connection that actually somehow forms a single unit out of many. That could be possible, as weird as it sounds, since we are made up of distinct parts that together form a unity.Yohan

    I'm simply relating the fact that a group of individuals united by a common purpose/goal can be and is treated as one entity. For example, in politics, something you should be familiar with, we refer to capitalists, socialists, fascists, and so on and in religion, we have christians, buddhists, moslems, jews, etc.. These are not single individuals but entire classes/categories of people. As individuals (one) they don't stand a chance against their adversaries, if any, but together, as a group (one) they're a force to reckon with.

    Metaphysically speaking, the matter is slightly complicated. Are groups/classes/categories, united as they are, the same, metaphysically, as the individuals that comprise them? Is the demographic christians identical in every respect to a christian? They seem to behave like each other.

    "One" is a concept, so in the fields of metaphysics, it can be:

    (1) Weakness;
    (2) Strength;
    (3) Weakness and Strength.

    Only after "becoming" through the human conception unto the world that it decides what the option will be.

    causality and chanceJack Cummins

    I don't know how else to get my point across except in that a one-off event that fits the description of synchronicity is exactly that - acausal. However, there should be some kinda limit to the number of synchronicities experienced, beyond which we might have to make an effort to seek a causal explanation. Have you encountered anyone who's a synchronicity magnet? Are there documented cases of multiple synchronicities? I don't think so. I'm not sure though.

    By the way, I used to be big fan of Jung's synchronicity theory - it feeds my inclination for mystery. Now, I've come to the realization that it's just an ordinary person's way of yearning for just that thing to make life extraordinary. Unfortunately, a lot has to be sacrificed - reason being the first casualty - to that end.
  • What does hard determinism entail for ethics ?
    It depends on how you define free will. If you ask your friend if he wants coffee or tea and he chooses coffee, do you say: "That wasn't free will, because that was clear since the Big Bang, please choose what you really want!"?SolarWind

    We have choices. Like it or not, as per the argument which I simply reproduced, none of the choices you make are free i.e. they're determined by forces beyond our control. That should cover all the bases, no?
  • Synchronicity, Chance and Intention
    A synchronicty, last I checked, is a meaningful coincidence. Imagine the following scenarios.

    1. You're walking down a street, thinking of nothing in particular. You look to your left and on the wall is a Coca cola advertisement. You then bump into someone. You turn to apologize and you realize that the person in front of you is the CEO of Coca Cola. Coincidence, meaningful.

    2. You and your friend are in a deli. As you chow down on the burgers you ordered, you discuss Will Smith (the actor) and his movie I am legend. Just as one of you say "Will Smith", Will Smith walks by on the sidewalk outside the deli. Coincidence, meaningful.

    3. You're in your room, quite bored. You lie down on the bed and a random thought - a police car chase you saw on the idiot box. Just then, two squad vehicles zoom past your room, sirens blaring. Coincidence, meaningful.

    The reason why synchronicity gives you that sense of meaning is the probability of it occurring - near zero. Too, why some interpret it as causation is because, again, of its likelihood - near zero.

    One crucial possibility that has to be ruled out in causal attribution is chance and the extremely low/zero probability of the conjunction of putative causes and effects. You can see where this is going.

    Synchronicity, by definition, as per Carl Gustav Jung himself, is acausal, a clear sign that Jung knew he was dealing with coincidences and not causation. If he had said there was a causal angle to it, he wouldn't have used "coincidence" in his very thought-provoking idea.

    You might find the following to be an interesting conversation (transcribed from an interview) between Hannah Fry (mathematician) and Prof. Ivette Fuentes (quantum physicist).

    Hannah Fry: It seems that there's quite a lot of uncertainty in quantum physics. Does that bother you?

    Prof. Ivette Fuentes: No, when I heard that things were, you know, uncertain and also against our common sense in quantum physics then I thought, oh wow!, that sounds interesting, I want to know more about that.

    Hannah Fry: Ok, alright, I'll tell you what then, quantum physics lesson 101, where do we start?

    Prof. Ivette Fuentes: Ok, I would say we have to start with superposition. So, let's talk about electrons. So, they're very small particles and they can be in two states, spin, and the spin can be pointing up or down. So, if we were in the classical world, the spin could only be either up or down but in the quantum world, the spin is in a superposition which it means it can be up and down at the same time.

    Hannah Fry: In the quantum world you can have your cake and eat it too. Alright, tell me about entanglement then.

    Prof. Ivette Fuentes: Ok, so take two electrons. If the electrons are entangled, and if I do something to one of the electrons, for example change the direction of the spin, that will instantaneously affect the state of the other electron even if they're separated (by) long distances.

    Hannah Fry: How far are they from each other?

    Prof. Ivette Fuentes: Well they can be a few centimeters but now the latest experiments, using satellites, show entanglement across 1,200 km.

    Hannah Fry: What? You've got something over here and something 1,200 km away. You do something to one and the other one instantly knows what's happened?

    Prof. Ivette Fuentes: Yes, you affect the state of the other one instantly.

    Hannah Fry: Apparently, there is no causal link. The only thing we can say is that the two particles are synchronized. How does one know what the other one is doing?

    Prof. Ivette Fuentes: Well, that we're still trying to understand because that's what mathematics tells us and then we can show it in the experiment but we're still struggling to understand what that means. And one of the reason why we don't understand it in, you know, like you're asking is because we don't see it in our everyday lives. So, let's say it's not part of our experience and common sense but that doesn't mean it doesn't happen.
  • What does hard determinism entail for ethics ?
    I quite like this deceptively simple argument:

    1. The laws of nature [premise]

    2. We are part of nature [premise]

    Ergo,

    3. No free will [conclusion]

    unless...

    1 is false - there are no laws of nature [try hard and you might be able to see it]

    and/or

    2 is false - we are not part of nature [we might not be]

  • Contradiction/Contrary (Sentential logic/Categorical logic)
    Update

    Sentential logic

    1. Dogs exist = D

    Categorical logic

    1 becomes,

    2. Some dogs are existent things [particular categorical statements have existential import]

    Predicate logic

    2 becomes,

    3. (Ex)(Dx) = Something is a dog, where Dx = x is a dog

    Sentential logic

    4. Unicorns don't exist

    Categorical logic

    4 becomes,

    5. No unicorns are existent things

    Predicate logic

    5 becomes,

    6. ~(Ex)(Uz) = (Ax)(~Ux) = Every thing is not a unicorn

    Look at 6. The only way, "every thing is not a unicorn" is if every thing exists; if not, we can't say (Ax)(~Ux).

    This suggests, to me, that if merely a thing then, existence is implied. Parmenidean!

    A dilemma presents itself: Unicorns exist OR Unicorns are nothing!

    St. Anselm of Canterbury...

    God is a thing (cataphasis). Ergo, must exist OR God is nothing (apophasis)!

    You might as well; after all you're a good philosopher, it should be a piece of cake.
  • Philosphical Poems
    Just for fun, using 'MadFool' because I needed a two-syllable extendable name…

    The MadFool, trapped in a cave by a poem,
    As by the writing on the wall stranded,
    Was martially both right and left handed;
    Such he slashed rhythms and rhymes from the stone.

    Madfool sights an ominous type of cloud,
    And shakes, hearing thunderous rhymes so loud,
    Just having survived the meters’ melodies
    And scans, with the ten syllables allowed.

    He runs breathless through meadow and forest,
    Fast pursued by the stings of wind and rain;
    On and on he pushes, wild without rest,
    Searching for haven from the forum’s pain.

    The storm chases him till he can go no more;
    He stands helpless, backed up against a door,
    But falls through it before death can touch him,
    Saved by the library admitting him.

    He wanders deep, down the poetic path,
    Aglow in the soft beauty that it hath.
    He sees John Keats kissing Fanny Brawne,
    As he spoke more than words but less than song.

    And Byron, endowing form with fancy,
    While Wordsworth pens his thoughts to Lucy,
    And Shelley, plumbing depths of mystery.
    He reads them all; they grow his poet-tree.

    Deeper still he probes, looking in on it,
    And hears Mrs. Browning reading a sonnet.
    Poetically, he takes them all in, even
    The shadowy Emily Dickenson.

    As soon as the lightning storm is past,
    The MadFooler enters the courtyard vast.

    Here the secret garden, half as old as time,
    Where poets live and write their words and rhyme,
    While the nightingale creates the rose,
    By moonlit magic, from their thoughts sublime.

    Literary scenes unfold before him,
    Such as music approaches and surrounds,
    And builds on the vibrance which in one is—
    To fill with beautiful visions and sounds.

    His quick thoughts rise, mist wafting from the dew,
    As living dreams unveil more than he knew.
    From poetry’s light the garden grew,
    Revealing mysterious wonders new.

    There MadFool relaxes, up against a tree,
    Savoring the feeling of the poetry,
    Where all the flowers used in Shakespeare’s plays
    Grow together in a living bouquet.

    :blush:

    TheMadFool trapped;
    wishes wings he could've flapped.
    To flee the hunger and/or the greed;
    his body eaten/sold, his mind bought/freed.

  • Contradiction/Contrary (Sentential logic/Categorical logic)
    Perhaps I'm the only one, but I have no idea what any of this means.Tom Storm

    If you're not pulling my chain, can you go study classical logics (sentential, categorical and predicate logics) and St. Anselm's ontological argument and give the issue I'm wrestling with here a second look. Thanks.
