The “Law of Conservation of Information, which runs as follows: No process of logical reasoning—no mere act of mind or computer-programmable operation—can enlarge the information content of the axioms and premises or observation statements from which it proceeds… deduction merely makes explicit information that is already there. It is not a procedure by which new information can be brought into being…"

“The Law of Conservation of Information makes it clear that from observation statements or descriptive laws having only empirical furniture there is no process of reasoning by which we may derive theorems having to do with first and last things… I [personal comment by Medawar] do not believe that revelation is a source of information, though I acknowledge that it is widely believed to be so—and that Coleridge judged theology Queen of the Pure Sciences for that very reason.”
