A certain denomination regularly included comments in the preface to the bible that it should only be read in the presence of clergy, so that if a question arose, they would be able to tell the reader what they should think about it. God forbid the reader form an opinion of their own.
Come to think about it, this analogy applies to lawyers & politicians, writing laws in such a manner to befuddle those less fluent in legalese. We should have a constitutional amendment that requires all laws to be written in a manner that a fifth grader would understand, and that all laws pertaining to a particular issue (e.g. firearms) be located in one section of the code for easy reference. Sure, and that going to happen!
