Logical Fail Here: "Earlier you said that it is justifiable to base one's beliefs about the external world on a firm, inner conviction, regardless of the external evidence, or lack of it, for the truth or falsity of this conviction. But now you do not accept that the rapist Peter Sutcliffe was justified in doing just that. The example of the rapist has exposed that you do not in fact agree that any belief is justified just because one is convinced of its truth. So you need to revise your opinion here. The intellectual sniper has scored a bull's-eye!"
