Famous quotes containing the words list of, list, impossible and/or puzzles:
“A man’s interest in a single bluebird is worth more than a complete but dry list of the fauna and flora of a town.”
—Henry David Thoreau (1817–1862)
“Shea—they call him Scholar Jack—
Went down the list of the dead.
Officers, seamen, gunners, marines,
The crews of the gig and yawl,
The bearded man and the lad in his teens,
Carpenters, coal-passers—all.”
—Joseph I. C. Clarke (1846–1925)
“It is impossible to give a clear account of the world, but art can teach us to reproduce it—just as the world reproduces itself in the course of its eternal gyrations. The primordial sea indefatigably repeats the same words and casts up the same astonished beings on the same sea-shore.”
—Albert Camus (1913–1960)
“Woman and fool are two hard things to hit,
For true no-meaning puzzles more than wit.”
—Alexander Pope (1688–1744)
