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.
I don’t think this is an appropriate community to post a self-post philosophical question… This community is specifically for posting science articles.
My genuine advice to you is to take an entry level philosophy course at a local community college.
If that’s not affordable/feasible, buy/pirate entry level philosophy textbooks. Or at least look up Descartes and epistemic self-doubt.
