Guerrilla ontology is a practice inspired by guerrilla warfare, described by Robert Anton Wilson as an ontological method of dealing with people with extremely fixed worldviews.
In The Illuminati Papers, Wilson defines guerrilla ontology as: "The basic technique of all my books. Ontology is the study of being; the guerrilla approach is to so mix the elements of each book that the reader must decide on each page 'How much of this is real and how much is a put-on?'" The use of guerrilla ontology is to present through mainstream media conflicting worldviews to dissuade the populace from ascertaining underlying realities.
