For I dipt into the future, far as human eye could see

from "Locksley Hall" (1842) 
Lord Tennyson's

"For I dipt into the future, far as human eye could see, 
Saw the Vision of the world, and all the wonder that would be; 
Heard the heavens fill with shouting, and there rain'd a ghastly dew 
From the nations' airy navies grappling in the central blue; 

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."
