Famous quotes containing the word table:
“When I think of our lands I think of the house
And the table that holds a platter of pears,
Vermilion smeared over green, arranged for show.”
—Wallace Stevens (1879–1955)
“But hospitality must be for service, and not for show, or it pulls down the host. The brave soul rates itself too high to value itself by the splendor of its table and draperies. It gives what it hath, and all it hath, but its own majesty can lend a better grace to bannocks and fair water than belong to city feasts.”
—Ralph Waldo Emerson (1803–1882)
“The newspaper is a Bible which we read every morning and every afternoon, standing and sitting, riding and walking. It is a Bible which every man carries in his pocket, which lies on every table and counter, and which the mail, and thousands of missionaries, are continually dispersing. It is, in short, the only book which America has printed, and which America reads. So wide is its influence.”
—Henry David Thoreau (1817–1862)
