Medical scientists use the word `iatrogenic' to refer to disabilities that are the consequence of medical treatment. We believe that some such word might be coined to refer to philosophical difficulties for which philosophers themselves are responsible Sir Peter Medawar Arguing that quantum theory as it stands is perhaps the most comprehensive, well-verified, and successful theory in the history of science, the author clears away the impression that it is an incomplete, philosophically flawed, and self-contradictory theory. In simple terms accessible to anyone with a little prior knowledge of science, Wallace examines the numerous paradoxes and difficulties claimed for quantum mechanics, and shows that they are due to excesses of interpretation that have been imposed on the theory.1.
