Robert Anton Wilson 1932 - present. Author of the Schroedinger's cat Trilogy, a complex spoof of conspiracy theory and possibly intermingled with truth. Also co-author (with Robert Shea) of the Illuminatus! trilogy. He also holds a Ph.D in Psychology and was once a writer for Playboy magazine.
Other books by Wilson include Quantum psychology and Reality is what you can get away with.
Some believe him to be one of the last surviving futurist thinkers.
