The shrewd, calculating commercialism which tries all human relations by pecuniary standards, the acquisitiveness which cannot rest while there are competitors to be conquered or profits to be won, the love of social power and hunger for economic gain-these irrepressible appetites had evoked from time immemorial the warnings and denunciations of saints and sages. Plunged in the cleansing waters of later Puritanism, the qualities which less enlightened ages had denounced as social vices emerged as economic virtues. They emerged as moral virtues as well. For the world exists not to be enjoyed, but to be conquered. Only its conqueror deserves the name of Christian. For such a philosophy, the question, "What shall it profit a man?" carries no sting. In winning the world, he wins the salvation of his own soul as well.
