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.
In addition to traditional answers (Plato, Solipsism, Descartes, …) this question is also the next-to-last step of coming of age: the realization that other people have minds, feelings, reasons, memories, and existences as complex, varied, and real as your own.
Though, rather excitingly, this does not reduce the questions.
