I do not believe that the tendency is to make men and women brave and glorious when you tell them that there are certain ideas upon certain subjects that they must never express; that they must go through life with a pretence as a shield; that their neighbors will think much more of them if they will only keep still; and that above all is a God who despises one who honestly expresses what he believes. For my part, I believe men will be nearer honest in business, in politics, grander in art — in everything that is good and grand and beautiful, if they are taught from the cradle to the coffin to tell their honest opinion.
