ochho a dit:
About the bubble experience article you linked to. Although I still find Micheal Hoffman's choice of wording very difficult to understand, I can see what he's talking about. It reminds me of something Alan Watts said that goes along the lines that we each live in our own universe that is created by our mind. And that while the color blue is "blue" to me, it might be "red" (under my definition of "red") to you, and there's no way of finding out. We just agree to refer to the color of banana as "yellow" and so on..
(Correct me if I'm wrong, but I think I remember something along these lines ;p)
That point by Watts is exactly the point Hoffman is making in the article, the whole universe is a subjective appearance being generated by YOUR brain. It is a deeper level of scepticism that just saying 'colours might appear differently to other people', it is saying that
even other people might not exist (ie solipsism might be true), there might not be any other people, since other people are all part of the subjective hallucination that you refer to as 'the world'
In philosophy it is often referred to as the 'brain in a vat' principle, the appearance of being a human with a body living a life might arise because you are a brain suspended in a chemical vat, your sensory experiences are being 'fed' to you by the vat, so everything you perceive as being 'real' is actually just a chemically-induced hallucination
