Excerpts from Books and Wikipedia
"With the standards of the peoples plunging thro’ the thunder-storm; Till the war-drum throbb’d no longer, and the battle-flags were furl’d
In the Parliament of man, the Federation of the world.
There the common sense of most shall hold a fretful realm in awe,
And the kindly earth shall slumber, lapt in universal law."
“Locksley Hall” had a profound effect upon Truman, and for years he kept a clipping of the lines . . . When puzzled senators and staffers asked Truman about his commitment to international organization, at the 1945 San Francisco conference and later, he was happy to reach into his wallet and read that passage from “Locksley Hall.” Most times, his listeners got the point. Mankind was going to destroy itself unless it invented some form of international organization to avoid conflict and advance the common humanity." [Kennedy: Parliament of Man, Kindle, Location 40-50]
