Famous quotes containing the words small and/or engines:
“The ancestral deed is thought and done,
And in a million Edens fall
A million Adams drowned in darkness,
For small is great and great is small,
And a blind seed all.”
—Edwin Muir (1887–1959)
“America is like one of those old-fashioned six-cylinder truck engines that can be missing two sparkplugs and have a broken flywheel and have a crankshaft that’s 5000 millimeters off fitting properly, and two bad ball-bearings, and still runs. We’re in that kind of situation. We can have substantial parts of the population committing suicide, and still run and look fairly good.”
—Thomas McGuane (b. 1939)
