Success in the formal scientific investigation of phenomena has always required that man learn to speak formally about the phenomena under investigation. Psychic phenomena are considered in terms of the unresolved problem of the relation between mind and matter, with paraphysics being defined as the physics of paranormal processes. This essay, chapter 19 of Psychic Exploration, explores why modern science has been unable to deal with highly complex systems and has therefore been able to address only certain kinds of problems. The full volume of Psychic Exploration can be purchased as an ebook or paperback version from all major online retailers and at cosimobooks.com.
