It is part of our American folk-lore that sooner or later a criminal will return to the scene of his crime. And perhaps it is a bad conscience which brings me to this topic. Nonetheless, if indeed this paper be an exercise in the amendment of life, I take comfort in the fact that a confession of sin is hardly a profession of achievement. Consequently, if at the close of this paper I leave this topic no better than I found it, the effort will yet have been a phase in my amendment of life. I do not think that any of us will come easily or quickly to an adequate understanding of how greatly we all must change our ways. Nor will the change itself be accomplished by mere good intentions.
