Famous quotes containing the words counter, machine and/or models:
“The technological landscape of the present day has enfranchised its own electorates—the inhabitants of marketing zones in the consumer goods society, television audiences and news magazine readerships... vote with money at the cash counter rather than with the ballot paper at the polling booth.”
—J.G. (James Graham)
“Much that is natural, to the will must yield.
Men manufacture both machine and soul,
And use what they imperfectly control
To dare a future from the taken routes.”
—Thom Gunn (b. 1929)
“Grandparents can be role models about areas that may not be significant to young children directly but that can teach them about patience and courage when we are ill, or handicapped by problems of aging. Our attitudes toward retirement, marriage, recreation, even our feelings about death and dying may make much more of an impression than we realize.”
—Eda Le Shan (20th century)
