Famous quotes containing the words standard, pitch and/or circle:
“An indirect quotation we can usually expect to rate only as better or worse, more or less faithful, and we cannot even hope for a strict standard of more and less; what is involved is evaluation, relative to special purposes, of an essentially dramatic act.”
—Willard Van Orman Quine (b. 1908)
“Though I have locked my gate on them
I pity all the young,
I know what devil’s trade they learn
From those they live among,
Their drink, their pitch and toss by day,
Their robbery by night....”
—William Butler Yeats (1865–1939)
“Wise child, didst hastily return
And mad’st thy mother’s womb thine urn.
How summed a circle didst thou leave mankind
Of deepest lore, could we the center find!”
—Ben Jonson (1572–1637)
