Brian Josephson, PhD, is Professor of Physics at Cambridge University and winner of the 1973 Nobel Prize for physics for his work on discovering the Josephson tunnelling effect in superconductivity. He is currently director of the Mind-Matter Unification Project of the Theory of Condensed Matter Group at the Cavendish Laboratory, Cambridge, a project concerned primarily with the attempt to understand from the viewpoint of the theoretical physicist what may loosely be characterized as intelligent processes in nature associated with brain function or with some other natural process. "From the viewpoint of the theoretical physicist" means that there is a particular concern with general principles and the way these may help to reshape one's perspective on a problem.

He says that one of his guiding principles is "the scientist's motto 'Take nobody's word for it' (nullius in verba), a corollary of which is that if scientists as a whole denounce an idea this should not necessarily be taken as proof that the said idea is absurd: rather, one should examine carefully the alleged grounds for such opinions and judge how well these stand up to detailed scrutiny."
