Famous quotes containing the words terms, flight and/or planning:
“Books have their destinies like men. And their fates, as made by generations of readers, are very different from the destinies foreseen for them by their authors. Gulliver’s Travels, with a minimum of expurgation, has become a children’s book; a new illustrated edition is produced every Christmas. That’s what comes of saying profound things about humanity in terms of a fairy story.”
—Aldous Huxley (1894–1963)
“Its shrill scream seems yet to linger in its throat, and the roar of the sea in its wings. There is the tyranny of Jove in its claws, and his wrath in the erectile feathers of the head and neck. It reminds me of the Argonautic expedition, and would inspire the dullest to take flight over Parnassus.”
—Henry David Thoreau (1817–1862)
“My consciousness-raising group is still going on. Every Monday night it meets, somewhere in Greenwich Village, and it drinks a lot of red wine and eats a lot of cheese. A friend of mine who is in it tells me that at the last meeting, each of the women took her turn to explain, in considerable detail, what she was planning to stuff her Thanksgiving turkey with. I no longer go to the group.”
—Nora Ephron (b. 1941)
