Famous quotes containing the word table:
“Comes the time when its later
and onto your table the headwaiter
puts the bill,”
—Robert Creeley (b. 1926)
“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 webecause we dont 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 (18861968)
