A criminal is literally a person accused--accused, and in the modern sense of the word convicted, of being harmful to Society. But is he there in the dock, the patch-coated brawler or burglar, really harmful to Society? is he more harmful than the mild old gentleman in the wig who pronounces sentence upon him? That is the question. Certainly he has infringed the law: and the law is in a sense the consolidated public opinion of Society: but if no one were to break the law, public opinion would ossify, and Society would die. As a matter of fact Society keeps changing its opinion. How then are we to know when it is right and when it is wrong? The Outcast of one age is the Hero of another. In execration they nailed Roger Bacon's manuscripts out in the sun and rain, to rot crucified upon planks--his bones lie in an unknown and unhonoured grave--yet to-day he is regarded as a pioneer of human thought. The hated Christian holding his ill-famed love-feasts in the darkness of the catacombs has climbed up to the throne of S. Peter and the world. The Jew moneylender whom Front-de-Boeuf could torture with impunity is become a Rothschild--guest of princes and instigator of commercial wars; and Shylock is now a highly respectable Railway Bondholder. And the Accepted of one age is the Criminal of the next. All the glories of Alexander do not condone in our eyes for his cruelty in crucifying the brave defenders of Tyre by thousands along the sea-shore; and if Solomon with his thousand wives and concubines were to appear in London to-morrow, even our most frivolous circles would be shocked, and Brigham Young by contrast seem a domestic model. The judge pronounces sentence on the prisoner now, but Society in its turn and in the lapse of years pronounces sentence on the judge. It holds in its hand a new canon, a new code of morals, and consigns its former representative and the law which he administered to a limbo of contempt. It seems as if Society, as it progresses from point to point, forms ideals--just as the individual does. At any moment each person, consciously or unconsciously, has an ideal in his mind toward which he is working (hence the importance of literature). Similarly Society has an ideal in its mind. These ideals are tangents or vanishing points of the direction in which Society is moving at the time. It does not reach its ideal, but it goes in that direction--then, after a time, the direction of its movement changes, and it has a new ideal.
