It was contended in the first chapter of this book that social morality is developed through sentiment and action. In this particular age we can live the truth which has been apprehended by our contemporaries, that truth which is especially our own, only by establishing nobler and wiser social relations and by discovering social bonds better fitted to our requirements. Warfare in the past has done much to bring men together. A sense of common danger and the stirring appeal to action for a common purpose, easily open the channels of sympathy through which we partake of the life about us. But there are certainly other methods of opening those channels. A social life to be healthy must be consciously and fully adjusted to the march of social needs, and as we may easily make a mistake by forgetting that enlarged opportunities are ever demanding an enlarged morality, so we will fail in the task of substitution if we do not demand social sympathy in a larger measure and of a quality better adapted to the contemporaneous situation. Perhaps the one point at which this undertaking is most needed is in regard to our conception of patriotism, which, although as genuine as ever before, is too much dressed in the trappings of the past and continually carries us back to its beginnings in military prowess and defence. To have been able to trace the origin and development of patriotism and then to rest content with that, and to fail to insist that it shall respond to the stimulus of a larger and more varied environment with which we are now confronted, is a confession of weakness; it exhibits lack of moral enterprise and of national vigor.
