Famous quotes containing the word table:
“the moderate Aristotelian city
Of darning and the Eight-Fifteen, where Euclid’s geometry
And Newton’s mechanics would account for our experience,
And the kitchen table exists because I scrub it.”
—W.H. (Wystan Hugh)
“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)
“Life is a thin narrowness of taken-for-granted, a plank over a canyon in a fog. There is something under our feet, the taken-for-granted. A table is a table, food is food, we are we—because we don’t question these things. And science is the enemy because it is the questioner. Faith saves our souls alive by giving us a universe of the taken-for-granted.”
—Rose Wilder Lane (1886–1968)
