Famous quotes containing the words output, high and/or light:
“Lizzie Borden took an axe
And gave her mother forty whacks;
When she saw what she had done,
She gave her father forty-one.”
—Anonymous. Late 19th century ballad.
The quatrain refers to the famous case of Lizzie Borden, tried for the murder of her father and stepmother on Aug. 4, 1892, in Fall River, Massachusetts. Though she was found innocent, there were many who contested the verdict, occasioning a prodigious output of articles and books, including, most recently, Frank Spierings Lizzie (1985)
“What generous beliefs console
The brave whom Fate denies the goal!
If others reach it, is content:
To Heavens high will his will is bent.
Firm on his heart relied,
What lot soeer betide,
Work of his hand
He nor repents nor grieves,
Pleads for itself the fact,
As unrepenting Nature leaves
Her every act.”
—Ralph Waldo Emerson (18031882)
“When the spirit brings light into our minds, it dispels darkness. We see it, as we do that of the sun at noon, and need not the twilight of reason to show it us. This light from heaven is strong, clear, and pure carries its own demonstration with it; and we may as naturally take a glow-worm to assist us to discover the sun, as to examine the celestial ray by our dim candle, reason.”
—John Locke (16321704)
