Famous quotes containing the word earth:
“Our roots are in the dark; the earth is our country. Why did we look up for blessinginstead of around, and down? What hope we have lies there. Not in the sky full of orbiting spy-eyes and weaponry, but in the earth we have looked down upon. Not from above, but from below. Not in the light that blinds, but in the dark that nourishes, where human beings grow human souls.”
—Ursula K. Le Guin (b. 1929)
“Man hath still either toys or care:
But hath no root, nor to one place is tied,
But ever restless and irregular,
About this earth doth run and ride.
He knows he hath a home, but scarce knows where;
He says it is so far,
That he has quite forgot how to go there.”
—Henry Vaughan (16221695)
“Once the sin against God was the greatest sin, but God died, and so these sinners died as well. To sin against the earth is now the most terrible thing, and to esteem the entrails of the unknowable more highly than the meaning of the earth.”
—Friedrich Nietzsche (18441900)
