Context: Therefore, we should devote ourselves as a preparative to preparedness, alike in peace and war, to secure the three elemental things: one, a common language, the English language; two, the increase in our social loyalty citizenship absolutely undivided, a citizenship which acknowledges no flag except the flag of the United States and which emphatically repudiates all duality of intention or national loyalty; and third, an intelligent and resolute effort for the removal of industrial and social unrest, an effort which shall aim equally at securing every man his rights and to make every man understand that unless he in good faith performs his duties he is not entitled to any rights at all.

Context: We will not build a peaceful world by following a negative path. It is not enough to say "We must not wage war." It is necessary to love peace and sacrifice for it. We must concentrate not merely on the negative expulsion of war, but on the positive affirmation of peace. There is a fascinating little story that is preserved for us in Greek literature about Ulysses and the Sirens. The Sirens had the ability to sing so sweetly that sailors could not resist steering toward their island. Many ships were lured upon the rocks, and men forgot home, duty, and honor as they flung themselves into the sea to be embraced by arms that drew them down to death. Ulysses, determined not to be lured by the Sirens, first decided to tie himself tightly to the mast of his boat, and his crew stuffed their ears with wax. But finally he and his crew learned a better way to save themselves: they took on board the beautiful singer Orpheus whose melodies were sweeter than the music of the Sirens. When Orpheus sang, who bothered to listen to the Sirens? So we must fix our vision not merely on the negative expulsion of war, but upon the positive affirmation of peace. We must see that peace represents a sweeter music, a cosmic melody that is far superior to the discords of war.
