Irreducible Mind: Toward a Psychology for the 21st Century is a 2007 parapsychological book by Edward F. Kelly, Emily Williams Kelly, Adam Crabtree, Alan Gauld, Michael Grosso, and Bruce Greyson. It attempts to bridge contemporary cognitive psychology and mainstream neuroscience with the “rogue phenomena” studied in the field of parapsychology (mediumship, near-death experiences, mystical states, etc.)
