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?
How can I really know that people are responding to this question and not only AI? I have absolutely no proof that this forum could be real. Look at ChatGPT.
I have so many questions.
You can’t, because in fact your brain really creates images.
Healthy person most commonly sees images based on the light their eyes receive, but based on the quality of information you may interpret it wrongly. Especially light captured by side sight – here brain draws a big part of picture itself.
People with schozophrenia can see and hear non-existing people like we see real people. It can take them a lot of reasoning to verify if person they are seeing in fact real.
