If, for instance, they have heard something from the postman, they attribute it to a semi-official statement; if they have fallen into conversation with a stranger at a bar, they can conscientiously describe him as a source that has hitherto proved unimpeachable. It is only when the journalist is reporting a whim of his own, and one to which he attaches minor importance, that he defines it as the opinion of well-informed circles.
As records of courts and justice are admissible, it can easily be proved that powerful and malevolent magicians once existed and were a scourge to mankind. The evidence (including confession) upon which certain women were convicted of witchcraft and executed was without a flaw; it is still unimpeachable. The judges' decisions based on it were sound in logic and in law. Nothing in any existing court was ever more thoroughly proved than the charges of witchcraft and sorcery for which so many suffered death. If there were no witches, human testimony and human reason are alike destitute of value.
