For I dipt into the future, far as human eye could see,
 Saw the Vision of the world, and all the wonders that would be;
…
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.

Alfred, Lord Tennyson, “Locksley Hall” (1837)
