“"Ignorance has been our king. Since the death of empire, he sits unchallenged on the throne of Man. His dynasty is age-old. His right to rule is now considered legitimate. Past sages have affirmed it. They did nothing to unseat him.
"Tomorrow, a new prince shall rule. Men of understanding, men of science shall stand behind his throne, and the universe will come to know his might. His name is Truth. His empire shall encompass the Earth. And the mastery of Man ever the Earth shall be renewed. A century from now, men will fly through the air in mechanical birds. Metal carriages will race along roads of man-made stone. There will be buildings of thirty stories, ships that go under the sea, machines to perform all works.
"And how will this come to pass?" He paused and lowered his voice. "In the same way all change comes to pass, I fear. And I am sorry it is so. It will come to pass by violence and upheaval, by flame and by fury, for no change comes calmly over the world."”

Colombe's Birthday (1844)
Context: p>He gathers earth's whole good into his arms;
Standing, as man now, stately, strong and wise,
Marching to fortune, not surprised by her.
One great aim, like a guiding-star, above—
Which tasks strength, wisdom, stateliness, to lift
His manhood to the height that takes the prize;
A prize not near — lest overlooking earth
He rashly spring to seize it — nor remote,
So that he rest upon his path content:
But day by day, while shimmering grows shine,
And the faint circlet prophesies the orb,
He sees so much as, just evolving these,
The stateliness, the wisdom and the strength,
To due completion, will suffice this life,
And lead him at his grandest to the grave.
After this star, out of a night he springs;
A beggar's cradle for the throne of thrones
He quits; so, mounting, feels each step he mounts,
Nor, as from each to each exultingly
He passes, overleaps one grade of joy.
This, for his own good: — with the world, each gift
Of God and man, — reality, tradition,
Fancy and fact — so well environ him,
That as a mystic panoply they serve —
Of force, untenanted, to awe mankind,
And work his purpose out with half the world,
While he, their master, dexterously slipt
From such encumbrance, is meantime employed
With his own prowess on the other half.
Thus shall he prosper, every day's success
Adding, to what is he, a solid strength —
An aery might to what encircles him,
Till at the last, so life's routine lends help,
That as the Emperor only breathes and moves,
His shadow shall be watched, his step or stalk
Become a comfort or a portent, how
He trails his ermine take significance, —
Till even his power shall cease to be most power,
And men shall dread his weakness more, nor dare
Peril their earth its bravest, first and best,
Its typified invincibility.Thus shall he go on, greatening, till he ends—
The man of men, the spirit of all flesh,
The fiery centre of an earthly world!</p

1960s, The American Promise (1965)
Context: This was the first nation in the history of the world to be founded with a purpose. The great phrases of that purpose still sound in every American heart, North and South: "All men are created equal" — "government by consent of the governed" — "give me liberty or give me death." Well, those are not just clever words, or those are not just empty theories. In their name Americans have fought and died for two centuries, and tonight around the world they stand there as guardians of our liberty, risking their lives. Those words are a promise to every citizen that he shall share in the dignity of man. This dignity cannot be found in a man's possessions; it cannot be found in his power, or in his position. It really rests on his right to be treated as a man equal in opportunity to all others. It says that he shall share in freedom, he shall choose his leaders, educate his children, and provide for his family according to his ability and his merits as a human being.
