Famous quotes containing the word wheel:
“Helpless, unknown, and unremembered, most human beings, however sensitive, idealistic, intelligent, go through life as passengers rather than chauffeurs. Although we may pretend that it is the chauffeur who is the social inferior ... most of us, like Toad of Toad Hall, would not mind a turn at the wheel ourselves.”
—Ralph Harper (b. 1915)
“Of the wheel as it rolls unrelentingly over
A cow plodding through car-traffic on a street in Iasi,
And over the haunts of Robert Pinsky’s mother and father
And wife and children and his sweet self”
—Robert Pinsky (b. 1940)
“You do me wrong to take me out o’ th’ grave:
Thou art a soul in bliss, but I am bound
Upon a wheel of fire, that mine own tears
Do scald like molten lead.”
—William Shakespeare (1564–1616)
