Famous quotes containing the word table:
“They were not on the table with their elbows.
They were not sleeping in the shelves of bunks.
I saw no men there and no bones of men there.”
—Robert Frost (18741963)
“For who is greater, the one who is at the table or the one who serves? Is it not the one at the table? But I am among you as one who serves.”
—Bible: New Testament, Luke 22:27.
“How to attain sufficient clarity of thought to meet the terrifying issues now facing us, before it is too late, is ... important. Of one thing I feel reasonably sure: we cant stop to discuss whether the table has or hasnt legs when the house is burning down over our heads. Nor do the classics per se seem to furnish the kind of education which fits people to cope with a fast-changing civilization.”
—Mary Barnett Gilson (1877?)
