Psychoactives don't just filter your senses, they change reality (your own subjective reality, of course.)
Maybe there is a demon in my head giving me the illusion of reality being perceived as a projection on the cerebral cortex, and it's reliable malleability under caffeine, MDMA, LSD, cannabis and so on. If so, I find this model of better utility than going with vibes and prayer and belief in eternity and so on that comes with the descendants of christian dualism in liberalism, 'panpsychism', analytic philosophy, &c.
Edit: Kierkegaard wrote quite interesting texts about the structures of consciousness, I'd recommend The Sickness unto Death as a start. It has some of his best jokes.
Science moves very slowly and very fast in this area, slowly with regards to psychoactives due to stuff like politicians, fast in neuroscience where new technology has allowed leaps for decades, since the eighties or so.
Me too! And yeah and if it weren't for that guy I could be a perfectly adequate automaton instead of dealing with this 'consciousness' nonsense. :P
