Famous quotes containing the word action:
“A dramatist is one who believes that the pure event, an action involving human beings, is more arresting than any comment that can be made upon it.”
—Thornton Wilder (1897–1975)

“We have seen the city; it is the gibbous
Mirrored eye of an insect. All things happen
On its balcony and are resumed within,
But the action is the cold, syrupy flow
Of a pageant.”
—John Ashbery (b. 1927)
