Famous quotes containing the words dark and/or matter:
“A puff of wind, a puff faint and tepid and laden with strange odours of blossoms, of aromatic wood, comes out the still night—the first sigh of the East on my face. That I can never forget. It was impalpable and enslaving, like a charm, like a whispered promise of mysterious delight.... The mysterious East faced me, perfumed like a flower, silent like death, dark like a grave.”
—Joseph Conrad (1857–1924)
““Would you tell me, please, which way I ought to go from here?”
“That depends a good deal on where you want to get to,” said the Cat.
“I don’t much care where—” said Alice.
“Then it doesn’t matter which way you go,” said the Cat.
“Mas long as I get somewhere,” Alice added as an explanation.
“Oh, you’re sure to do that,” said the Cat, “if you only walk long enough.””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
