    The brain is our thinking device, but ultimately it’s “just” a clever piece of meat. But consciousness is something that exists outside the dimensions of space and time, yet is able to influence those dimensions. A higher-order dimension, if you will. That’s maybe a bit of a spiritually elusive way to frame it, but that’s because science cannot explain it either.

    Science knows there are other dimensions. Quantum physics proves this with entanglement and the particle-wave duality. Within quantum physics there is also the “magical” notion of the observer, where nobody knows exactly how to define what an observer. It seems linked to consciousness, but some people get very angry if you suggest that, because we cannot prove it and it breaks their illusion that physical reality is all there is.

    Anyway, if you are in the camp that thinks there is nothing beyond physical, then sure, it’s the brain. But if you’re a bit more open minded, then it’s also more than just the brain.

      consciousness is something that exists outside the dimensions of space and time

      That’s absolutely, demonstrably incorrect. It, like all the other processes, is something that exists in observable space-time dimensions that we can observe. It’s a state of matter observable over time. There is no way and no reason to add some more shit on top of that.

      there is also the “magical” notion of the observer

      It’s only magic if you don’t know what probability is. If we have two marbles, black and white, and blindly take one each and go on our merry ways, and then you need to do the full math about it for some reason, it’s very useful to you to describe a marble in my hand as a 50% black/ 50% white marble. Then later if you look at the one you have, and discover that it’s a white one, the one I have magically, instantly, inexplicably becomes 100% black marble. That’s what, simplifying a lot, a quantum effect is (this specific one is quantum entanglement). And if you forget that nothing actually changed, and it’s just you scribbling some math on a paper, you can start thinking about it in terms of reality bending multidimensional paradoxes. But it’s not, it’s just humans being unable to easily comprehend insanely complex mathematical abstractions.

        Do you have some source for that? Would love to see how you measure that?

        […] That’s what, simplifying a lot, a quantum effect is

        You’re also entirely ignoring the part where matter stops behaving as matter and starts interacting with itself as if you had the white and black marble in your hands at the same time, despite you only having one. This is the “magical” part, because it depends on the presence of the observer whether this effect happens or not.

          Do you have some source for that? Would love to see how you measure that?

          That’s the thing. You are the one adding an additional entity on top the reality, so you should be the one providing sources for it. We know what a brain is, we roughly know how it operates, we know that if we measure electrical activity we have perfectly working predicting theory, we can stick a person into an FMRA machine, prod a specific part of the brain and make them see purple, flail hands, or hear voices. Now, if you want to reintroduce old discarded theory of a soul into all that, it’s your job to find where it fits and find any way that it will work.
          My sources for it is the last century or so of the brain science.

          You’re also entirely ignoring the part

          Because this part doesn’t exist. It’s hard to overstate how much all of this is just math.
          The whole observer effect stems from the fact that we can’t measure quantum particles directly on account of it being too small, so we don’t have a way to know anything about them until we or something else interacts with them, usually in quite destructive ways. So in order for our math to exist, we abstract it away and talk about shit like 0.5 spin like it’s something that can make any sense in real life, just because nobody needs to explain every time that we’re talking about probability of an abstract particle in specific conditions. Because, again, we can only measure its, for example, speed by the fact that it smashed into something else with a specific force, and as you can imagine, its speed after that is quite different.
          If we return to the marble example, if my only way to tell a colour of it was to smash it to bits, we can say that the marble is in the state of black-white, but when I measure it, it changes the state to was-black-now-smashed-into-bits, thus demonstrating the observer effect. We can say that because we did a bunch of math and now we need a special black-white state of matter to make our probabilistic equations make sense. But without that, we stop at the black-white state and don’t go any further, because it’s not a thing that actually real.

            Regarding the quantum physics part, I was referring to the double slit experiment: https://en.wikipedia.org/wiki/Double-slit_experiment

            Matter can interfere with itself in wave patterns that behave as if the matter no longer exists in a single position, but in all possible positions at once. This shows the matter doesn’t even exist in its physical form anymore while it is part of the wave function. “Quantum particles” are not even a thing, because this effect can be reproduced with large molecules too, and there is no apparent upper limit to this: https://science-atlas.com/strange-news/largest-molecules-yet-become-waves-in-quantum-double-slit-experiment/

            This effect is real, and waving it away because it’s supposedly “too small” isn’t making it less so. It’s not too small to measure. The article mentions these molecules were fitting slits that were 50nm in size.

            As for the brain waves, it seems we’re talking about different things. Of course we can mess with the brain and alter sensory experiences. But experience and awareness are a bigger thing than merely input/output. That’s something I know to be true about myself, but I suppose you can reason that away. I merely pity those who do.

        But do you have an alternative explanation? Because without one, I have no alternative but to admit there must be something more, regardless of whether you wish to call it a dimension or something else.

        What we do know however, is that entanglement is not constrained to the dimensions of time and space. So the existence of additional dimensions seems a rather logical leap, even if indeed technically speculation, because we don’t know how they work.

            Sorry, but simply saying no doesn’t make it so. Entanglement directly contradicts the laws of general relativity when it comes to time and space, so either general relativity (and with that, everything we know about time and space) goes out the window, or there is more than just time and space. You can’t have it both ways.

              Those aren’t the only choices, and those are made up by people. The world doesnt change just because humans have obscure thoughts or fantastical explanations for things. Nothing is new now compared to a thousand years ago, and people didnt have souls back then either.

                Of course choices are made up by people. Science is made up by people. But if you use science to convince yourself that we have no soul, you better make sure there are no gaps in your reasoning. So long as science’s own experiments contradict each other with regards to the nature of our reality, I’m not going along with such denialism.

                  It’s weird that you don’t extend this formula to your position, and very outwardly advocating for an existance of inobservable substance solely on reasoning of “it’s dimensions or quantum or whatever”

                    Well, yeah, I’m not the one claiming to have all the answers. I merely am a witness of my consciousness, so I know that’s a real thing. I describe that whole of consciousness and awareness and “me-ness” as my soul, but I have no hard definition for it, I merely know there’s something there.

                    Science however is a man-made construct and can only operate on the observable and the independently verifiable. I’m not saying that to diminish its worth, because science is mighty cool, but I simply refuse to take it to the extreme position that anything that cannot be scientifically proven should be assumed not to exist.

                    I’ve experienced enough weird shit in my life that makes no scientific sense. They still happened though. So rather than denying these things, the sane thing to do is to shrug them off as “it’s dimensions or quantum or whatever” :)
