Famous quotes containing the words surface, equipment, connected, diving and/or work:
“In Manhattan, every flat surface is a potential stage and every inattentive waiter an unemployed, possibly unemployable, actor.”
—Quentin Crisp (b. 1908)
“Why not draft executive and management brains to prepare and produce the equipment the $21-a-month draftee must use and forget this dollar-a-year tommyrot? Would we send an army into the field under a dollar-a-year General who had to be home Mondays, Wednesdays and Fridays?”
—Lyndon Baines Johnson (1908–1973)
“War and culture, those are the two poles of Europe, her heaven and hell, her glory and shame, and they cannot be separated from one another. When one comes to an end, the other will end also and one cannot end without the other. The fact that no war has broken out in Europe for fifty years is connected in some mysterious way with the fact that for fifty years no new Picasso has appeared either.”
—Milan Kundera (b. 1929)
“all the fine
Points of diving feet together toes pointed hands shaped right
To insert her into water like a needle”
—James Dickey (b. 1923)
“The true finish is the work of time, and the use to which a thing is put. The elements are still polishing the pyramids.”
—Henry David Thoreau (1817–1862)
