How can I prove myself that my brain isn't just creating images so I can experience life? - Lemmy.World

How can I prove that everything I see really exists and isn’t just an illusion/ image created by my brain? How can I really know that once I look away from something that it is still there and doesn’t turn black? I thought about the mirror, but maybe the image in the mirror is also just created. The people I hear talking behind me could also be gone but I only hear the audio and once I turn around they appear visually. I thought about using a camera but the content that is saved on the camera could also be fake. Can someone tell me how to prove that others really exist?

Well, if other people and things don’t exist then it’s your brain creating your perception of reality. The physics of your world is consistent, You can test that. If reality is something your brain is making up, it would have to calculate the physics of everything you perceive instantly and constantly. It can’t do that.

If it could, how would YOU, the consciousness that is experiencing this made up reality, ever struggle with something like a math problem? It’s the same brain. The sheer scale of everything happening around you, how would your mind possibly calculate it as you experience it.

How would your mind know how something hot like a coffee should cool down depending on the temperature around it and the container it’s in and how that heat will affect things around it.

If this reality is real, it’s not being calculated, it’s happening, everywhere all the time. If it’s fake it has to be calculated or simulated for you. If your brain can’t simulate it, then it’d have to be something like a super computer quantum singularity thingamajig. If that’s doing it, then who created the computer?

If reality is real, then people are real. If reality is fake then people have to be real.

It can’t do that.

That’s not an argument. If you’re inside a virtual reality, what you perceive as true doesn’t have to be true at all. OPs brain can be capable of everything you said and more if you and I were just fragments of their imagination. What we know about the brain’s capabilities wouldn’t matter if this was a simulation.

The only real answer is that it doesn’t matter: if the whole world around you is made up by your brain, what does it matter if you can’t change it?
