There's no truth claims. The point is that under the influence of psychedelics, you realize you can't know the truth. I understand you're looking at it from a scientific point of view, but the discussion is not scientific. Consciousness is probably the hardest body of knowledge to integrate with science. Nobody knows where consciousness comes from. Nobody knows how to measure it. I can tell you: "I'm conscious and aware", but there's no way I can prove to you I'm not a philosophical zombie(someone that acts like it's conscious, but isn't). Currently, there's no way to measure consciousness. >By your own standards, I could ask how you know there's something called a brain, that it has something to do with perception, etc. Maybe you hallucinated the brain? Maybe it's just some weird belief you have? Maybe hallucinations aren't a thing? How do you know what other brains do or don't do differently? And why can't some of them be wrong? I think you nailed it. I don't know whether there's a brain, or if there is something else, and this something else is hallucinating this reality where there is a brain, or maybe something else entirely. Sure, we can make scientific claims about stuff when analyzing the reality within the bounds of our perception, but if you try to go beyondg that, you're own your own. |
You can't prove that to yourself either, because a zombie has the same thoughts as you. You can't differentiate even subjectively whether you're a zombie or not.
