What has weakened the moral fibre of our modern society so much that at times one wonders if we are living in the Christian era? If the home is now so often desecrated by theories of free love and trial marriages, if the cradles are empty, if the very sense of shame is a thing of the past, if the most elementary principles of morality are questioned, is it not because the public conscience is being warped, chloroformed, deadened by a frenzied propaganda of a corrupted Public Opinion? Has not the politician and the legislator the ear to the wind, the eye on the running tides and cross currents of thought, to know and sound Public Opinion? Like the skilful and watchful pilot, he counts with the set of the tide and catches it at its crest. He knows the exact height of the rising tide that will float him and his cargo over the bar . . . of a coming election--. This tide of public feeling has carried some to the high seas of success but left many stranded on the desert shores. Many public men indeed have set out on its angry waters to brave its fury . . . and have never returned. "In our times of Democracy when the "competitive" principle has replaced the "hereditary," not the kings, princes and nobles, but bankers, merchants, railroad magnates, capitalists, politicians, editors, educators, writers and artists occupy the high seats, hold the baton and beat the time for the great social orchestra." (Ross-Social Psychology.) "Power and influence," said Morley, "no longer reside in the Crown but in the strong, subtle forces called Public Opinion: and that Public Opinion is apt to involve fatal contentment with simple answers to complex questions." In the great international life of nations Public Opinion also holds the reins. This power manifests itself particularly at the great turning points of History, such as we are now witnessing. There is always then resistance between conflicting forces; and resistance, we know, strengthens the current. What power was at work for the last fifty years and marshalled, on that fatal August day of 1914, the formidable army that swept over Belgium, France and Russia? Public Opinion created by the military caste in Germany! What secret and growing force made of the Allies' contemptible army of yesterday the crushing victorious army of to-day?--The invincible power of Public Opinion!--It leaped from the very depths of the wounded heart and outraged conscience of nations, and created in a few months that unconquerable army of inexhaustible reserves upon which the Allies relied until their final triumph. It fired the morale of our armies and smashed the way to victory. For those who could not go to the battle-field, it kept the homefires burning and fringed with the silver lining of radiant hope the dark clouds that hung over our horizon for four long, dragging, weary years. 3. _How Public Opinion is Formed_.
