Famous quotes containing the word table:
“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 can’t stop to discuss whether the table has or hasn’t 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–?)
“The salt person and blasted place
I furnish with the meat of a fable;
If the dead starve, their stomachs turn to tumble
An upright man in the antipodes
Or spray-based and rock-chested sea:
Over the past table I repeat this present grace.”
—Dylan Thomas (1914–1953)
“A child who is not rigorously instructed in the matter of table manners is a child whose future is being dealt with cavalierly. A person who makes an admiral’s hat out of linen napkins is not going to be in wild social demand.”
—Fran Lebowitz (20th century)
