Argument from psychedelics

Further information: Philosophy of psychedelics

Human subjects in scientific studies have reported that psychedelic drugs such as LSD, mescaline, psilocybin mushrooms, and DMT provide perceptions of a transcendent reality, including encounters with God.^[92][93] Since prehistory, cultures around the world have used entheogens for the purpose of enabling mystical experiences. In The Doors of Perception, English philosopher and writer Aldous Huxley recounts his mystical experiences while he was under the influence of mescaline, arguing that the human brain normally filters reality, and that such drugs remove this filter, exposing humans to a broader spectrum of conscious awareness which he calls the "Mind at Large".
