Is their any scientifically sound reason to believe in an afterlife? Because the more I look into it, the more convinced I am that consciousness is created by the physical brain and once the brain dies, our consciousness also dies. This makes things like the mind-body problem very easy to solve.
And yet people, even educated ones, keep acting like this is still up for debate. What am I missing? Are the educated believers in an afterlife just grifting? I'm not afraid of an eternal dreamless sleep, but if there is a valid reason to believe that there is something beyond this existence that I can take part in, I would love to know.

Well, even though it’s likely, you’ll have to definitively prove that the brain is the sole engine for consciousness alone. Until then, the minuscule chance of qualia being generated by an outside force remains open

You can't explain why my subjective experience is tethered to THIS brain in particular. For an afterlife to not exist, this tethering would have to persist even after my brain has been destroyed. Otherwise, there would be nothing preventing my identity from just entering a different brain.

consciousness is electricity and since energy only changes forms and cant really cease to exist it would sound like it makes sense that the afterlife is the electrical energy freed from your body since brain isnt working anymore but i think the energy that becomes electricity in our brain stops being transferred when we die and theres nothing after

Because -this- brain -is- your subjective experience, there is no outside force creating your consciousness, it's just the manifestation of physical interactions, it's like asking why the electron has a charge, it's just a basic law of reality which dictates its behaviour, there is no components to further divide to, same applies to the conscious experience, just matter reacting. In essence "you" do not exist and are whatever physical components decided to come together and start interacting, more simply put the universe experiencing itself, a bacteria, a bug, a rabbit, a human, doesn't matter, all manifestations of the same thing, just at an increasing rate of complexity and thus capability to collect and process more information and make deductions based on the millions of inputs you are receiving every second, it's all an endless cycle with no escape.

parapsychology is science. It's not a very respected kind of science and often isn't carried out very well, but it is science none the less. A number of universities fund their research and sometimes other kinds of academics will do research into the paranormal/supernatural. Like this research into Near Death Experiences by a medical professor, which was of course inconclusive
https://psi-encyclopedia.spr.ac.uk/articles/aware-nde-study

But this site is probably the most scientific research you'll find on this kind of stuff. And while they do use scientific methods they tend to not really try to outright prove/disprove something, they often do all their analysis with statistics which results in probabilities of things occurring and this ends up not really resolving anything in terms of whether something is a real phenomenon or not

Probably not. But maybe. Quantum entanglement is probably the best example, where particles communicate with no apparent mechanism able to be detected. This is extremely strange and means either every particle can be connected across infinite distance, or that they actually are communicating via some kind of unknown mechanism that allows communication that is instantaneous. And that alone opens up a lot of possibilities. Obviously it's not really appropriate to start assuming every idea could use this mechanism in some way, but I think it does mean that ideas like dualism can't exactly be ruled out with what we currently know

If you believe that consciousness is an emergent property of a physical living brain, you don't need to explain the mechanism by which it is tethered to the brain, anymore than you need to explain how a wave is tethered to a body of water, or how the color of an apple is tethered to the apple. These are merely properties, and the existence of properties are dependent upon the existence of the things to which they belong. If the existence of a property is reliant upon energy, that energy will continue to exist, but I don't think you would argue that energy and consciousness are the same thing. I'm not saying that dualism is impossible, but physicalism requires fewer unjustified assumptions based on our current scientific knowledge. Also, the more we understand about the brain, the fewer unknowns we have to attribute to a non-physical soul. It's kind of like the god of the gaps, but in this case, it's the soul of the gaps, and it just keeps getting smaller.

One interpretation of how dualism could exist due to quantum mechanics is that it is related to wave-particle duality. Mental states are to waves what physical states are to particles.

>After: The behavior of the ant colony is the outcome of the interactions of many individual ants.
>Even better: A colony is made of ants. We can successfully predict some aspects of colony behavior using models that include only individual ants, without any global colony variables, showing that we understand how those colony behaviors arise from ant behaviors.

>2. Working on AI safety

>3. Thinking of ways of reducing the probability

>Suicide, depending on your theory on personal identity, may make the probability 0. If you believe that there is no difference between copies of you then there may be a possibility of being resurrected in the future however. As we aren't certain about what happens to the observer after death, it is unknown whether death will make worse than death scenarios impossible. I believe there are many ways in which it could reduce the probability, but the key question is: could it increase the probability? An argument against suicide is that it is more likely that people who commit suicide will go to "hell" than those who don't. This is because an entity who creates hell has values which accept suffering, making life a positive concept which should not be discarded. On the other hand, an entity with values related to efilism/antinatalism (philosophies in which suicide is generally accepted) would not create a hell at all. Of course, this is all based on a lot of speculation.

>There is a risk that the suicide attempt will fail and leave you in a disabled state. This could make you more vulnerable when considering indefinite worse than death scenarios. However, I would argue against this disadvantage because the only potential way to evade an entity powerful enough to cause these scenarios would be suicide, which always has a risk of failing.

Not arguing for physicalism but quantum entanglement doesnt involve any communication.
I dont think hidden variables are true but quantum entanglement makes it seem more plausible.
To explain quantum entanglement: imagine having two identical envelopee. In one you put a Red card and in one a blue card. Now seal them and mix them up. Theyre now in superposition and quantum entangled.
Go travel to the moon but leave one envelope behind. Now open the envelope. If you have the red card in it, you know that on earth they have the blue card.
Its pretty much that simple.

>> No.15857900

>>15857763
yeah i understand that. What i was saying that was entanglement is particles reacting to eachother over some distance without any form of traditional communication occurring. If you know the spin of one particle then you'll know the spin of the other without having to look at the other. But knowing the spin destroys the entanglement. But you can send one of those entangled particles through a polarizer to change its spin and the spin of the other will instantaneously change to reflect that, but again you won't know the result until you measure it, but that doesn't mean things aren't changing internally. That is the "communication" part. They're not communicating via electromagnetic waves though, obviously. It's happening as a function of the quantum field. But just the fact that is possible means that there might be other phenomena like that, where the state of one particle is determined by something else non-locally. The main point i'm making is that non-locality exists
