Convicts represent those wrong-doers who have taken to a particular form of wrong-doing punishable by law. Of the larger army of bad men they represent a minority, who have been found out in a peculiarly unsatisfactory kind of misconduct. There are many men, some lying, unscrupulous, dishonest, others cruel, selfish, vicious, who go through life without ever doing anything that brings them within the scope of the criminal code, for whose offences the laws of society provide no punishment. And so it is with some of those heroes of history who have been made the theme of fine writing by gifted historians.
