...The efficacy of psychedelics with regard to art has to do with their ability to render language weightless, as fluid and ephemeral as those famous "bubble letters" of the sixties. Psychedelics, I think, disconnect both the signifier and the signified from their purported referents in the phenomenal world - simultaneously bestowing upon us a visceral insight into the cultural mechanics of language, and a terrifying inference of the tumultuous nature that swirls beyond it. In my own experience, it always seemed as if language were a tablecloth positioned neatly upon the table until some celestial busboy suddenly shook it out, fluttering and floating it, and letting it fall back upon the world in not quite the same position as before - thereby giving me a vertiginous glimpse into the abyss that divides the world from our knowing of it. And it is into this abyss that the horror vacui of psychedelic art deploys itself like an incandescent bridge. Because it is one thing to believe, on theoretical evidence, that we live in a prison-house of language. It is quite another to know it, to actually peek into the slippery emptiness as the Bastille explodes around you. Yet psychedelic art takes this apparent occasion for despair and celebrates our escape from linguistic control by flowing out, filling that rippling void with meaningful light, laughter, and a gorgeous profusion.
