>>290People come to that conclusion without psychosis or drugs. Don't take this as me dismissing the idea of consciousness as fundamental and prior to what we label 'physical' reality instead of emergent from it, it's an interesting idea, one I think I support, but that fact that many people come to support that position isn't any weirder than the numerous convergence conclusions people reach on other ontological matters.
I do have to say that video from this artist comes across as pure cope from a person dealing with what sounds like a very serious case of schizophrenia. It's clear his belief in the philosophical ideas he brings up help him deal with the effect schizophrenia has on his life and the unfair abuse and criticism he receives for it.
