029-The physical world as qualia
Why do we have physical experiences and non-physical experiences? How, and why do we distinguish between unicorns and horses?
the reason we have physical experiences and non-physical experiences is because of representation. There is a body of representations that consistently go together, and this group of representations we call physical experience.
what do we mean by consistent in this context. We mean that there are a group of representations which co-occur.
the power of hallucinations is that the bulk of representations that are experienced that indicate physical experience co-occur with some representations that are atypical of physical experience. Psychedelic experience is when non-physical experiences co-occur with physical experience.
When the qualia we call physical experience co-occurs with the qualia of non-physical experience. Ordinarily this does not happen, because the co-occurance features of physical representations simply do not happen with the non-physical representations. The separation between the physical and non-physical is not a separation of fact, it is a separation of representation.
From an evolutionary point of view, it seems like it is a bad idea to mix up the two experiences regularly. But it's not a bad idea to mix them up sometimes. The fact that psychedelics work at all is a testament to the feature and advantages of hallucinatory and psychedelic experience. That is, hallucinations serve a survival advantage.
