Theory: I am God alone and I am hallucinating everything
I can't disprove solipsism at all. In fact, it seems like I'm able to consistently prove it. Solipsism can apply to a multiplicity meaning nothing exists outside of us too though. It can apply to the singular and a plurality.
"B-But bro you're low IQ!!!"
How? Being conscious, self aware, sentient. Being aware of the present moment necessitates me being a kind of fudamental essence. This is just plainly true. Words give that a label, but the fact that I am here seems to be evidence. Can I prove others are real? No. I can believe they are...
Maybe there is a we. Am I Brahman? The singular self? Probably.
I consider all possibilities. Maybe there are Brahmans, Singular selves, Gods. Plurality. But I don't know. Maybe I'm pretending I don't know. It feels like I know.
