In the article I dismiss the realist interpretation, because of Occam’s razor and because the weird sense of the experience’s obviousness and of its hyperreality fades away as you come down from the high, leaving you with ambivalence. The letdown seems similar to how mystical experience subsides as the mystic returns to the profane world and to her physical senses. The mystic is left to pick up the pieces with religious doctrines and metaphors that rarely do justice to the peak state of awareness.
The question might be whether the information we receive while in that higher state should be taken literally, or whether literal truth itself is only a profane, naturalistic conception. If we take the psychedelic state literally, we may be trivializing it by objectifying it.
