Famous quotes containing the word industrial:
“Coal is a portable climate. It carries the heat of the tropics to Labrador and the polar circle; and it is the means of transporting itself whithersoever it is wanted. Watt and Stephenson whispered in the ear of mankind their secret, that a half-ounce of coal will draw two tons a mile, and coal carries coal, by rail and by boat, to make Canada as warm as Calcutta, and with its comfort brings its industrial power.”
—Ralph Waldo Emerson (1803–1882)
“If you do not regard feminism with an uplifting sense of the gloriousness of woman’s industrial destiny, or in the way, in short, that it is prescribed, by the rules of the political publicist, that you should, that will be interpreted by your opponents as an attack on woman.”
—Wyndham Lewis (1882–1957)
